Bush tax cuts and economic growth
In 2001 and 2003, former U.S president George W. Bush signed Economic Growth and Tax Relief Act (EGTRAA) and Jobs and Growth Tax Relief Reconciliation Act (JGTRAA). EGTRAA reduced personal income tax rates, increased child tax credit, decreased estate tax and introduced a various range of tax-favored retirement savings plans. In 2003 when EGTRAA was enacted, the Congress cut the top capital gains tax rate from 20 percent to 15 percent while the individual dividend tax rate was reduced from 35 percent to 15 percent.
Bush tax cuts are set to expire in 2011. Hence, a bold increase in marginal tax rates is expected. David Leonhardt recently asked whether the Bush tax cuts were good for economic growth amid the fact that under Bush administration, the U.S economic growth was the lowest since the World War II. Eight years of Bush administration were known for the largest expansion of federal government spending compared to the six preceding presidents. In eight years, President Bush increased discretionary federal outlays by 104 percent compared to 11 percent increase under President Clinton.
Under Bush tax cuts, the reduction in personal income tax rates was imposed across all income brackets. Tax Policy Center estimated that extending Bush tax cuts in 2011 would increase the after-tax income across all income quintiles but it differed substantially. For instance, the increase in after-tax income in the lowest quintile would represent 12.19 percent of the increase in after-tax income of the highest quintile. The average federal tax rate would decrease by 2.5 percentage points. The reduction in average federal tax rate would be the most significant for top 1 percent and 0.1 percent cash income percentile, -3.8 percentage points and -4.4 percentage points respectively. Assuming the extension of the Bush tax cuts, the average federal tax rate, which includes indvidual income tax rate, corporate income tax rate, social security, Medicare and estate tax, would be substantially lower compared to Obama Administration's FY2011 Budget Proposal. The increase in the average federal tax rate would be roughly proportional across the cash income distribution. The federal tax rate would increase by 1 percentage point for the lowest quintile and 3.1 percentage point for the top quintile. The federal tax rate would for earners in top 1 percent of cash income distribution would increase by 4.2 percentage point. The chart shows the distribution of average effective tax rates and current law and current policy of Bush tax cuts not assumed to expire in 2011. The current proposal would increase the effective tax rate across all income quintiles. The highest increase (3.3 percentage points) would hit the earners in top 20 percent of income distribution.

The expiration of the Bush tax cuts would substantially increase the effective tax burden across the cash income distribution. Recently, Center on Budget and Policy Priorities estimated that letting the Bush tax cuts expire would create a net gain of $22 billion in economic activity. Hence, allowing high-income tax cuts expire would, on impact, result in a net gain of $42 billion in economic activity which is about five times the economic stimulus from extending high-income tax cuts.
The years of the Bush administration were earmarked by the escalation of federal government spending both in absolute and relative terms. The growth in federal government spending was driven mostly by discretionary defense spending while non-discretionary federal outlays increased as well. Since 2001, the federal government spending in the Bush administration increased by 28.8 percent with a 35.7 percent growth in non-defense discretionary spending. The growth of the federal government under Bush administration was the highest since the presidency of Lyndon B. Johnson and Richard Nixon. The Independent Institute compared the growth of federal government spending from Lyndon B. Johnson onwards.
Letting the Bush tax cuts expire would probably not impose a negative effect on small businesses since less than 2 percent of tax returns in the top 2 income brackets are filed by taxpayers reporting small business. William Gale contends that the Bush tax cuts significantly raised the government debt. The economic consequences of the 9/11 and wars in Iraq and Afghanistan were detrimental. William Nordhaus estimated that the total cost of war in Iraq between 2003 and 2012 could exceed $1 trillion in 2002 dollars considering unfavorable and protracted cost scenario. To a large extent, the wars in Iraq and Afghanistan have added substantially to the increase in government spending. However, even after excluding defense outlays from the spending structure, the increase in non-defense discretionary spending exceeded the growth of the federal government spending by 5.6 percentage points. Between 2000 and 2008, the number of federal subsidy programs increased from 1,425 to 1,804 - a 26 percent increase compared to 21 percent increase during Clinton years.
The Bush tax cuts failed to result in a Laffer curve effect mostly because they were implemented alongside a bold and significant increase in federal government spending. Had a substantial reduction in government spending been enforced, the tax cuts would not place should an enormous weight in the growth of federal debt. Higher federal debt would inevitably ponder the structural fiscal imbalance. Since debt interest payments would increase, a combination of tax cuts and spending growth would stimulate investment demand, creating an upward pressure on interest rates, especially during the economic recovery when the difference between potential output and real output is expected to diminish.
Critics of the Bush tax cuts often claim that cuts amassed a growing fiscal deficit. However, in 2007, the fiscal deficit stood at 1.2 percent of the U.S GDP while in 2009, the deficit increased to 9.9 percent of the GDP as a result of $787 billion fiscal stimulus from Obama Administration. Since tax cuts were enacted in 2001 and 2003 respectively, something else is to blame for the deficit.

The main premise of the economic policy of the Bush administration had been a significant increase in federal government spending. Spending policies were mostly aimed at covering the growing cost of the Iraqi war. In addition, domestic non-defense outlays on social security and domestic priorities grew significantly, creating an upward pressue on federal debt. The growth of entitlments such as Social Security and Medicare poses a serious long-term risk regarding the sustainability of federal government spending. In the upper chart built a simple forecasting framework to estimate the long-run level of U.S federal government debt as a percent of the GDP. Surprisingly, time trend accounts for 85 percent of the variability of the share of federal debt in the GDP. A more robust framework would include the lagged dependent variable and several regressors in the set of explanatory variables to increase the share of variance explained by independent effects of regressors. The results indicate that by 2020, the federal debt could easily reach the 90 percent thresold.
The growing stock of entitlements such as Social Security and Medicare are central to understanding the looming pressure on federal budget to tackle the challenges of ageing population and demand for health care. The tax cuts imposed by the Bush administration reduced average federal tax rates across quintiles in cash income distribution. However, tax cuts were no supplemented by the reduction in federal government spending. Consequently, the growth of federal government spending increased future interest debt payments and failed to take into account the long-term pressure of Medicare and Social Security on federal budget set. Extending the Bush tax cuts would be superior to letting them expire. But lowering tax burden should nevertheless be comprehended by the reduction in federal government spending.

OPEC AND THE LOGIC OF CARTELS
Recently, the Organization of Petroleum Exporting Countries (OPEC) celebrated its 50th anniversary (link). The organization was founded in 1960 with the purpose of regulating world's oil prices and controlling the supplies of oil. Currently, OPEC controls 80 percent of world's proven oil reserves and its 12 member states oil production capacity accounts for 40 percent of world's total oil production.
Source: The Economist (link)
As a profit-maximizing monopolist, OPEC is faced with a downward sloping demand curve and upward sloping marginal cost curve which represents the market supply curve of the orgaization's 12 member states. As a profit-maximizing agent, OPEC countries equate marginal cost of production and marginal revenue from oil supplies and thus extract the entire consumer surplus from oil importing countries such as the United States, Japan and the European Union. There are several plausible explanation of OPEC's monopoly power in the world oil market. First, oil is a good with no close substitutes. Thus, the price elasticity of oil demand curve is significantly price inelastic. The average empirical estimate of the world price elasticity of demand for oil is -0.4, suggesting that a 10 percent increase in the price of oil would, on average, reduce the market demand for oil by 4 percent, ceteris paribus.
The relationship between the total revenue of the monopolist and the elasticity of demand suggests that the unit elasticity of demand is the revenue-maximizing point elasticity of demand for the monopoly firm such as OPEC. As the graph shows, OPEC's price spikes occured mostly during external shocks such as the 1973 oil shocks, Arab-Israeli war and the recent financial crisis. The spikes in the world price of oil reflected the pure logic of OPEC's cartel. By pushing the price upward, OPEC countries realized that, in the short run, the price elasticity of demand for oil is even more inelastic, thus reducing the consumer surplus of oil importing countries while expanding the producer surplus of OPEC member states.
The strategic behavior of OPEC mostly depends on the nature of external shocks affecting the production capacity and reserves of world's oil supplies. During political conflicts, the short-run demand for oil spiked and, therefore, the price elasticity of demand for oil decreased, increasing OPEC's short run producer surplus. Thereupon, OPEC member states set oil production quotas which exactly reflected the organization's intention to extract the entire consumer surplus from oil importing countries. Also, during the pre-2008 economic boom, the economic growth in emerging markets further inflated the world price of oil since the OPEC's short run production capacity outpaced the quotas set by the organization. But during the recent financial crisis, the short-run response of OPEC has been the reduction of per barrel oil price as an strategic step towards maintain the stability of market demand for oil. During the recent crisis, personal consumption and incomes have fallen substantially and therefore, assuming the positive income elasticity of demand for oil, the world demand for oil decreased considerably. The change in the aggregate consumption of oil has led to relatively more price elastic demand for oil. Partly, the increase in the price elasticity of oil is explained by the technological innovation and market access to long-run substitutes of oil such as fuel-efficient and electric vehicles and electric cars.
The technological development of fuel-efficient vehicles has decreased the monopoly power of OPEC by increasing the price elasticity of demand for oil due to the availibility of closer substitutes. In the follow-up of the financial crisis, the OPEC set the per barrel price of oil at $75. Given the downward sloping market demand curve, the short-run oil consumption increased and OPEC thus raised the relative price of oil's substitutes since it acknowledged the switching costs of changing the consumption of durable goods which complement the consumption of oil. What OPEC did is that it attempted to establish the short-run price elasticity of oil close to unity and, thereby, effectively increase the total revenue of the organization's member states. However, if in the long run, the market demand for oil was elastic, the net effect of increasing the price of oil, would incidentally fall on the burden of OPEC producers. Therefore, relatively price inelastic demand and price elastic oil supply is the main source of OPEC's monopoly power in the world oil market.
The rationale behind the cartelled market organization of oil supply is the stability of demand for oil across the world. Could OPEC's monopoly power, in effect, be broken if one country would set asymmetric prices on the global oil market. The desire of OPEC member states to fully collude in the cartel is the well-known phenomena from industrial organization known as the trigger strategy. According to trigger strategy, a member of the cartel is likely to divert from the cartel's strategy only if long-term gains outpace short-term losses of acting in accordance with the cartel's strategic behavior. In purely theoretical terms, if Nash equlibrium exists in the long-term benefits of cooperation, the diversion from cartel's strategic behavior, will not be feasible.
Even though some OPEC member states face asymmetric market demand curves in the short run, the stability of world oil demand embodied in the relatively price inelastic oil demand decrease the feasibility of defection from the cartel's strategic targets, discounted benefits from the collusion far outpace potential short-term losses.

The economic future of Ireland
Following the beginning of the 2008/2009 economic and financial crisis, Ireland was hit by an unprecedent economic slowdown. In 2008, the GDP declined by 3.0 percent on the annual basis. In 2009, the GDP further declined by 7.1 percent in real terms. The unemployment rate increased to almost 12 percent.
Prior to the outburst of the economic crisis, Ireland enjoyed stable and predictable levels of public debt. In 2007, the country was known for having stabilised the public debt at 25 percent of the GDP - the lowest level of any Western European country. In 2009, the debt-to-GDP ratio increased to 64 percent of the GDP. Once known as the sick man of Europe, Ireland's economic policymakers have implemented a set of fiscal policy measures aimed to boost the long-term economic growth and abolish the economic policy based on the state intervention, high tax rates on labor and capital and export-led growth.
Eversince the 1960, Ireland pursued a soft version of industrial policy targeted at the promotion of inward foreign direct investment and the education of highly skilled workers. In addition, Ireland reduced the corporate income tax rate to 12.5 percent and provided a thorough technical assistance and to multinational companies located in Ireland. Indeed, U.S. multinationals such as Microsoft, Dell and Intel were encouraged to locate in Ireland mainly because of its geographic proximity to key European markets, skilled English-speaking workforce, membership in the EU, relative low wage level and favorable corporate taxation.
In early 1990s, the results of a precise set of economic policies were spectacular. By the end of 2006, the unemployment rate dropped to 4.6 percent from 18 percent in early 1980s. Between 1992 and 2005, Irish GDP increased by an average of 6.9 percent while the investment grew by 8.6 percent on the annual basis. The largest contribution to GDP growth was domestic demand (5.3 percentage point). Hence, Ireland's public finance enjoyed a favorable outlook mainly due to the rapid decline of debt-to-GDP ratio from 1980s onwards, and from a relatively low demographic pressure on the budgetary entitlements.
During the Irish boom, Irish banking and financial sector were highly dependant on the wholesale funding. Due to largely positive macroeconomic outlook from 1990 onwards, Irish banking sector received high and consistent credit ratings from agencies such as Moody, S&P and Fitch. In turn, the reliance on fragile wholesale funding resulted in overleveraged balance sheets. After the failure of Lehman Brothers in September 2008, the short-term outlook on Irish banking sector signalled a significant rise in credit-default swaps which raised concerns over the ability of banks to provide the wholesale funding for a mountain of short-term debt liabilities. And since the overleveraged balance sheets downgraded the outlook on Irish banking sector, the institutional investors demanded higher risk premium to extend the funding channel to the Irish banks.
The Directorate Generale for Economic and Financial Affairs of the European Commission downgraded the macroeconomic forecast of Irish GDP growth. By the end of 2009, the economic activity plummeted by 7.1 percent. The housing market crash was largely a result of the asset price bubble channeled through the overinvestment in the construction sector which represented 12 percent of the GDP. Nothing could explain the deflationary pressures in the aftermath of the financial crisis than excessive housing prices during the pre-crisis Irish economic boom. After 2008, Ireland's household savings rate increased to the level above 10 percent which is a result of the adjustment in the household balance sheet. In fact, between 2001 and 2007, the share of household debt in the GDP nearly doubled.
Meanwhile, the mountain of liabilities in the Irish banking and financial sector raised the concern over its solvency. The Irish Government immediately facilitated a bailout plan for the troubled banking sector. Consequently, the large budget deficit resulted in excessive debt-to-GDP ratio which grew by 39 percentage points between 2007 and 2009. In the annual European Economic Forecast (Spring, 2010), the European Commission estimated that by the end of 2011, the debt-to-GDP ratio could reach as high as 87.3 percent. while the cyclically-adjusted government balance is estimated to increase up to -10.2 percent of the GDP. The contraction of domestic demand which, by all measures, is the main engine of Ireland's economic growth led to a rapid increase in the unemployment rate which increase from 6.3 percent in 2008 to 11.9 percent in 2009. By 2011, the European Commission forecast that the unemployment rate is expected to further increase by 1.5 percentage point compared to 2009. In World Economic Outlook, the IMF estimated that the unemployment rate in Ireland would increase by 1.1 percentage point by the end of 2011. In 2009, Ireland experienced net outward migration for the first time since 1960s in the wake of expected 13.8 percent unemployment rate in 2010.
The macroeconomic forecast for 2011 is favorable. The European Commission upgraded GDP growth estimate to 3 percent. Meanwhile, the investment is expected to increase for the first time since the 60 percent cumulative decline of the construction sector. The positive contribution of net exports to the gradual narrowing of the current account deficit could be an important measure to alleviate the rising pressure over debt-to-GDP ratio. On the other hand, Ireland's Department of Finance revised the macroeconomic forecasts and estimated that by the end of this year, the GDP would grow by 1 percent on the annual basis.
The essential measure of Irish economic recovery is the retrenchment of wage rates in the public sector and the adjustment of public sector wages to the cyclical dynamics of economic activity to prevent the possibility of excessive inflationary pressures in the course of economic recovery. Current measures of retrenching public sector wages successfully anchored the inflationary expectations. According to the IMF, the annual inflation rate is estimated to peak at nearly 2 percent by the end of 2015. The falling wage rates in the private sector could induce the reallocation of resources in the tradeable sector, further adding to the contribution of net external trade to the GDP growth.
The key measures to alleviate the consequences of economic and financial crisis in both real and financial sector are the immediate narrowing of Ireland's excessive budget deficit and public debt in the share of GDP. High public debt is mainly the result of government capital injection into Anglo-Irish Bank which represents about 2 percentage points of net deficit increase in 2010. The entire consolidation package represents 2.5 percent of the GDP.
Deutsche Bank recently published Public Debt in 2020 and estimated the levels of public debt by the end of that year for both advanced and emerging-market economies. The analysis by Deutsche Bank predicted the effect of a combined negative shock in real interest rate, primary government balance and real GDP growth. If the combined shock of all three variables were to change by about one-fourth standard deviation from the estimated growth rate, the public debt in 2020 would reach 154 percent of the GDP. If the combined shock of all three variables increased by one-half standard deviation from the baseline estimates, the public debt in 2020 would increase to 197 percent of the GDP. The difference in the estimated increase is due to higher intensity of the combined shock. In addition, to restore the debt-to-GDP ratio to pre-crisis level, Ireland would be required to increase the primary government balance to 6 percent of the GDP.
Given the enormous magnitude and burden of public debt and overleveraged corporate and financial sector, the immediate facilitation of measures to alleviate the public indebtedness is necessary. Ireland's economic future is constrained by the persistence of budget deficit which adds to the future burden of public debt. Prudent efforts to reduce the burden of both debt and deficit are of the essential importance. Nevertheless, Irish policymakers should not neglect the economic policies that created the Irish miracle as well as the policy errors that caused the deepest economic decline in Western Europe during the 2008/2009 economic crisis.
Eversince the 1960, Ireland pursued a soft version of industrial policy targeted at the promotion of inward foreign direct investment and the education of highly skilled workers. In addition, Ireland reduced the corporate income tax rate to 12.5 percent and provided a thorough technical assistance and to multinational companies located in Ireland. Indeed, U.S. multinationals such as Microsoft, Dell and Intel were encouraged to locate in Ireland mainly because of its geographic proximity to key European markets, skilled English-speaking workforce, membership in the EU, relative low wage level and favorable corporate taxation.
In early 1990s, the results of a precise set of economic policies were spectacular. By the end of 2006, the unemployment rate dropped to 4.6 percent from 18 percent in early 1980s. Between 1992 and 2005, Irish GDP increased by an average of 6.9 percent while the investment grew by 8.6 percent on the annual basis. The largest contribution to GDP growth was domestic demand (5.3 percentage point). Hence, Ireland's public finance enjoyed a favorable outlook mainly due to the rapid decline of debt-to-GDP ratio from 1980s onwards, and from a relatively low demographic pressure on the budgetary entitlements.
During the Irish boom, Irish banking and financial sector were highly dependant on the wholesale funding. Due to largely positive macroeconomic outlook from 1990 onwards, Irish banking sector received high and consistent credit ratings from agencies such as Moody, S&P and Fitch. In turn, the reliance on fragile wholesale funding resulted in overleveraged balance sheets. After the failure of Lehman Brothers in September 2008, the short-term outlook on Irish banking sector signalled a significant rise in credit-default swaps which raised concerns over the ability of banks to provide the wholesale funding for a mountain of short-term debt liabilities. And since the overleveraged balance sheets downgraded the outlook on Irish banking sector, the institutional investors demanded higher risk premium to extend the funding channel to the Irish banks.
The Directorate Generale for Economic and Financial Affairs of the European Commission downgraded the macroeconomic forecast of Irish GDP growth. By the end of 2009, the economic activity plummeted by 7.1 percent. The housing market crash was largely a result of the asset price bubble channeled through the overinvestment in the construction sector which represented 12 percent of the GDP. Nothing could explain the deflationary pressures in the aftermath of the financial crisis than excessive housing prices during the pre-crisis Irish economic boom. After 2008, Ireland's household savings rate increased to the level above 10 percent which is a result of the adjustment in the household balance sheet. In fact, between 2001 and 2007, the share of household debt in the GDP nearly doubled.
Meanwhile, the mountain of liabilities in the Irish banking and financial sector raised the concern over its solvency. The Irish Government immediately facilitated a bailout plan for the troubled banking sector. Consequently, the large budget deficit resulted in excessive debt-to-GDP ratio which grew by 39 percentage points between 2007 and 2009. In the annual European Economic Forecast (Spring, 2010), the European Commission estimated that by the end of 2011, the debt-to-GDP ratio could reach as high as 87.3 percent. while the cyclically-adjusted government balance is estimated to increase up to -10.2 percent of the GDP. The contraction of domestic demand which, by all measures, is the main engine of Ireland's economic growth led to a rapid increase in the unemployment rate which increase from 6.3 percent in 2008 to 11.9 percent in 2009. By 2011, the European Commission forecast that the unemployment rate is expected to further increase by 1.5 percentage point compared to 2009. In World Economic Outlook, the IMF estimated that the unemployment rate in Ireland would increase by 1.1 percentage point by the end of 2011. In 2009, Ireland experienced net outward migration for the first time since 1960s in the wake of expected 13.8 percent unemployment rate in 2010.
The macroeconomic forecast for 2011 is favorable. The European Commission upgraded GDP growth estimate to 3 percent. Meanwhile, the investment is expected to increase for the first time since the 60 percent cumulative decline of the construction sector. The positive contribution of net exports to the gradual narrowing of the current account deficit could be an important measure to alleviate the rising pressure over debt-to-GDP ratio. On the other hand, Ireland's Department of Finance revised the macroeconomic forecasts and estimated that by the end of this year, the GDP would grow by 1 percent on the annual basis.
The essential measure of Irish economic recovery is the retrenchment of wage rates in the public sector and the adjustment of public sector wages to the cyclical dynamics of economic activity to prevent the possibility of excessive inflationary pressures in the course of economic recovery. Current measures of retrenching public sector wages successfully anchored the inflationary expectations. According to the IMF, the annual inflation rate is estimated to peak at nearly 2 percent by the end of 2015. The falling wage rates in the private sector could induce the reallocation of resources in the tradeable sector, further adding to the contribution of net external trade to the GDP growth.
The key measures to alleviate the consequences of economic and financial crisis in both real and financial sector are the immediate narrowing of Ireland's excessive budget deficit and public debt in the share of GDP. High public debt is mainly the result of government capital injection into Anglo-Irish Bank which represents about 2 percentage points of net deficit increase in 2010. The entire consolidation package represents 2.5 percent of the GDP.
Deutsche Bank recently published Public Debt in 2020 and estimated the levels of public debt by the end of that year for both advanced and emerging-market economies. The analysis by Deutsche Bank predicted the effect of a combined negative shock in real interest rate, primary government balance and real GDP growth. If the combined shock of all three variables were to change by about one-fourth standard deviation from the estimated growth rate, the public debt in 2020 would reach 154 percent of the GDP. If the combined shock of all three variables increased by one-half standard deviation from the baseline estimates, the public debt in 2020 would increase to 197 percent of the GDP. The difference in the estimated increase is due to higher intensity of the combined shock. In addition, to restore the debt-to-GDP ratio to pre-crisis level, Ireland would be required to increase the primary government balance to 6 percent of the GDP.
Given the enormous magnitude and burden of public debt and overleveraged corporate and financial sector, the immediate facilitation of measures to alleviate the public indebtedness is necessary. Ireland's economic future is constrained by the persistence of budget deficit which adds to the future burden of public debt. Prudent efforts to reduce the burden of both debt and deficit are of the essential importance. Nevertheless, Irish policymakers should not neglect the economic policies that created the Irish miracle as well as the policy errors that caused the deepest economic decline in Western Europe during the 2008/2009 economic crisis.

Artificial states
The question of the artificial states has recently been brought up by the referendum in Southern Sudan on whether the southern part of the country should declare political independence from the northern part of the country. An article in New York Times (link) succintly discussed few notable fact-checked evidence of the increasing ethnic, political and economic North-South division within the country. As a single country, Sudan performed terribly in development outcomes. According to CIA World Factbook (link), the country suffers from high rates of extreme poverty and illiteracy. For instance, the official share of population below poverty line is estimated at 40 percent - almost twice the average of North African states. In addition to poor development outcomes, the country is plagued by significant political and ethnic fragmentation into largely Muslim, Arab-speaking north and predominantly Christain, English-speaking south. The political independence of South Sudan is the only contemporary evidence of the re-establishment of land borders alongside the ethnic division.
In the recent paper entitled Artificial States, Alberto Alesina, William Easterly and Janina Matuszeski presented two formal measures of artificial states. Aside from the measure of ethnic division, the authors constructed the measure of straightness of border lines. The hypothesis suggests that squiggly geographic border lines separate the states alongside the ethnic division. On the contrary, straight border lines suggest increase the probability of the emergence of artificial states plagued by ethnic and linguistic fractioning. The authors presented the empirical evidence, suggesting that fractional land borders are highly correlated with the GDP per capita. In addition, the share of ethnically partitioned population within the country is systematically decreasing the GDP per capita in cross-country comparison. The intuitive ideas behind the empirical evidence suggest that at the end of colonial period, colonizers that set straight borderlines between the emerging countries incured significant economic cost to newly formed African countries in terms of lost GDP. The evidence from Alesina-Easterly-Matuszeski study suggest that a 1 percentage point increase in the fraction of country's population belonging to groups partitioned by the border would decrease the GDP per capita by 1.3 percent. On the other hand, countries with squiggly geographic borderlines enjoy significantly higher GDP per capita.
The post-colonial period in Sudan was characterized by two civil wars which outbroke in 1972 and 1983. In 1956, Sudan gained the political independence from Great Britain. Contemporary borderlines were predominantly determined by the colonial authorities in African states prior to the wave of independence of many African nations. The emergence of the artificial states is rather a consequence of poor colonial policies than of high bargaining cost of ethnic groups within the country in setting country borderlines. Hence, the economic effects of colonial legacy can persist over time. Consider the evidence from Cameroon. The country was originally colonized by Germany. During the World War I, Northern Cameroon was occupied by Germany while the rest of the country was colonized by the French. Between 1916 and 1960, the country was a unique experiment of how the establishment of the institutional setting of European countries affects domestic development outcomes. A recent study by Alexander Lee and Kenneth Schultz (link) suggests that in the areas formerly occupied by the British enjoy higher levels of wealth and improved access to clean water while the rest of the rural country, after having been colonized by the French, suffers from significantly hindered access to clean water and worse provision of public goods. Even though the colonial patterns do not apply to urban areas, lessons from Cameroon suggest that the impact of post-independence public policies and colonial legacy on the level of wealth is of the same importance even when linguistic and ethnic fragmentation persists over time.
In spite of considerable degree of inefficiency, the persistence of inefficient and ethnically fragmented states is continuously marked by poor economic and development outcomes, often accompanied by civil-war conflicts such as military violence and genocide by the Sudanese army in Darfur. An interesting theory has been recently put forth by Daron Acemoglu, Davide Ticchi and Andrea Vindigni (link) who suggest that rich political elites seize state capture and democratic politics by expanding the size of bureaucracy. Hence, to gain political support, the coalition of elites chooses an inefficient structure and organization of the state.
The phenomenon of artificial states is not abridged to least-developed countries and developing world. Even in the group of advanced countries, several countries emerged despite a considerable degree of linguistic, ethnic and cultural fractioning within country borders. The evidence from Switzerland suggests that a continuous transition to a peaceful and stable democracy is possible. Amid highly fragmented linguistic and cultural characteristics such as four official languages and the persistence of GDP per capita divergence between high-income German cantons and low-income French cantons, Switzerland is characterized by envious political stability and economic performance. The genuine feature of federal political system is a consistent fiscal decentralization such as jurisdictional competition between units within the federalized structure in various areas such as taxation, regulation, health care etc. Hence, a decentralized fiscal structure and division of powers require a limited federal government and a high degree of autonomy within the federation. Thus, despite a multilingual population, the Swiss model of federalism is marked by political stability, peace and prosperity.
The phenomenon of artificial states in advanced countries is not confined to Switzerland itself. What distinguishes the Swiss model of federalism from centralist political systems in its neighboring countries is a high degree of political autonomy in Swiss cantons. Competition between jurisdictions within the federation nonetheless generates different economic outcomes. However, the outcomes generated by jurisdictional competition preclude adverse effects caused by either state capture of democratic politics or redistributive taxation between jurisdictions. In Switzerland, cantons with favorable public policies such as low tax rates on labor and capital, sound regulation and competitive provision of health care, have enjoyed persistently higher levels of wealth compared to cantons in the rest of the country. Of course, the coexistence of diverse ethnic and lingual groups within the single state requires common values, integrated into formal institutions.
Contrary to common perception, the artificial state may not be characterized exclusively by ethnic and linguistic fragmentation. To a large extent, Germany and Belgium could be classifed as artificial states. In Belgium, Flemmish-speaking north of the country consistently outperformed French-speaking south on various indicators and outcomes, including income per capita, international test scores and employment-to-population ratio. The political and linguistic division of Belgium into high-income Flemmish part and less developed French part reflects the essential dilemma of artificial states - should a single country with fragmented and heterogenous population be abandonded and whether ethnicity borders should represent country borderlines. In fact, linguistic fragmentation of Belgium to the extent that Flemmish and French part of the country adopted different administrative and education systems, led to persistent inability of two majorities to form a government. In 2007, The Economist opined that Belgium should cease to exist. The unification of Germany (Wiedervereinigung) integrated two parts of the country with vastly different institutional setting into a single political unity. However, Eastern and Western Germany were known for completely different political and economic system. The unification has incured many adverse effects. A significant difference in wage and price levels between East Germany and West Germany caused continuous migration of East German labor into West Germany, thus decreasing the productivity growth in East Germany. Consequently, the unification of the country led to the adoption of West Germany level of prices and wages in Eastern part of the new country. The artificial increase in price-wage level increased the unemployment rate in Eastern Germany to double-digit level, not least triggered brain-drain and capital flight. Hence, the unification of Germany as an artificial state resulted in persistent income per capita divergence between high-income West Germany and low-income East Germany. The unification of Germany into a single country should indeed never happen. In fact, adverse effects of the unification on East German productivity and wages would not lead to continuous increase in unemployment rate. If East Germany maintained a high degree of political autonomy, the transition to market economy would not be restrained by the adoption of West German price-wage level that could not be sustained by low productivity level in East Germany. To avoid the pitfalls of the artificial states, West and East Germany would be better off, had the countries never been reunified.
Recent national referendum in South Sudan on whether the southern part of the country should declare political independence from Sudan again pondered over the persistence of artificial states. The empirical evidence on poor development outcomes in several African countries suggests that borderlines, disregarding the ethnic distribution of the population within the country, are highly correlated with low income per capita. The unique solution of the artificial states is the adoption of political federalism. Under fiscal decentralization and limited government, federalism enables peaceful and prosperous existence of fragmented ethnic and linguistic structure in a single state. For instance, former Yugoslavia, known for highly fragmented ethnic, linguistic and economic disparities, ceased to exist not because federalism would not be a genuine political system but, ultimately, because of severe economic mismanagement, powerful and centralized government that disdained the principles of political autonomy and market economy, causing severe hyperinflation and the collapse of the federation that eventually resulted in a decade of civil wars and military violence. The evidence from Yugoslavia suggests that between 1950 and 1990, drastic economic divergence occured. The lesson suggests that the essential condition for the efficiency of federalism as a political system is high political autonomy and fiscal decentralization, both of which enable the competition between public policies.
Amid linguistic fragmentation, the competition between jurisidictions rewards competitive public policies by higher income per capita which ultimately boost the inception of public policies in less developed parts of the federation. Hence, without jurisdictional competition and political autonomy, ethnic and linguistic fragmention of the country may ultimately result in political instability which, in addition, generates poor economic outcomes.

Student performance and economic growth
The 2009 PISA test study (link) of students' proficiency in reading, mathematics and science is a highly successful method of evaluating student performance across countries. In fact, the creation of human capital is the main endogenous feature of the long-run economic growth since the quality of schooling and education system are essential to the creation of human capital. The difference in GDP per capita across countries is both intuitive, theoretical and empirical challenge to search for the causes of the gap between the economic performance of nations.
PISA test scores are aimed mainly at the evaluation of student knowledge at primary and secondary level in the fields of reading, mathematics and science. The assessment of knowledge in a particular field is subdivided into six different proficiency levels, ranging from 1 to 6. For instance, students at the 1st reading proficiency level are characterized by innate recognition of simple ideas reinforced in the text while students at the 6th reading proficiency level are characterized by a full capability of making multiple inferences, comparisons and contrasts and integrating the ideas presented in the text into a coherent conceptual framework of abstract ideas, sound evaluation and reflection. While 98.6 percent of OECD students can perform reading tasks at level 1, only 1.1 percent of students across OECD countries can perform reading tasks at the highest proficiency level. In addition, 28.4 percent of students in OECD countries exceeded the 4th (mid-range) reading proficiency level.
The reading scale has been further divided in reading continuous and non-continuous texts. However, the evidence suggest no systematic difference in reading scores between the two fields. Countries with the highest performance, measured as mean score, in reading rank are Korea (89.8 percent), Finland (89.3 percent) and Canada (87.3 percent). Countries with the largest student populations such as United States, United Kingdom and France were ranked in the upper-middle range while percent, and Israel (79 percent), Luxembourg (78.6 percent) and Austria (78.3 percent) are the lowest-ranking high-income countries on the reading scale in the 2009 PISA assessment. In the field of mathematics, 8 percent of students in OECD countries perform below level 1, 31.4 percent of students can perform mathematical tasks at 4th (mid-range) proficiency level while 3.1 percent of students perform at the highest proficiency level. In the country distribution, the percentage of students in the 6th proficiency level is the highest in Korea and Switzerland (8 percent), Japan, Belgium and New Zealand (5 percent). In a regional distribution, more than 25 percent of students in Shanghai perform at the highest level of mathematical proficiency. The proportion of students in the 6th proficiency level is very high in Singapore, Chinese Taipei and Hong Kong - 15.6 percent, 11.3 percent and 10.8 percent respectively. In addition, performance disparity in mathematics varied significantly across countries. Less than 1 percent of students in Mexico, Chile, Greece and Ireland reached 6th proficiency level A brief overview of the main empirical findings suggests a rather rigorous disparities in country ranking and performance.
The assessment of student performance in science is similar to the distribution of mean scores in the field of mathematics. About 5 percent of students perform below 1st proficiency level. In addition, only 29.4 percent of the students in OECD countries is proficient at 4th (mid-range) proficiency level in science while an average 1.1 percent of students in OECD countries can perform at the highest level of scientific literacy. In addition, the percentage of students below the lowest level of scientific proficiency is highly negatively correlated with country ranking since the proportion of students below the 1st level is the lowest in Finland (8.3 percent), Korea (6.3 percent), Estonia (8.3 percent) and Canada (9.6). Higher country ranking would thus indicate a lower proportion of students below the 1st proficiency level. All of the aforementioned countries ranked in the highest 10 percent of the distribution. If Shanghai, Hong Kong, Macao and Taipei were independent countries, their respective ranking in the field of scientific literacy would be in the top 10 percent of the distribution.
The empirical data on the distribution of mean scores in reading, mathematics and science are highly relevant to the measurement of human capital since the impact of mean scores on economic growth would differ to the certain extent from other measures of human capital. Recent attempts to capture the effect of human capital on economic growth were aimed at the definition of human capital as total years of primary, secondary and tertiary schooling. For instance, Robert Barro and Jong Wha Lee have collected disaggregated data on the total years of schooling for 146 countries between 1950 and 2005 at five-year intervals (link). The empirical evidence from the country panel suggests a strong linkage between schooling and long-run economic growth and institutional country features (link). In addition, Barro and Lee estimated the implicit return from an additional year of schooling ranging from 5 percent to 12 percent.
Gary Becker (link) and Richard Posner (link) recently discussed the 2009 PISA findings and the impact of cultural, genetic and demographic disparities on mean test scores in the United States. United States ranked in the middle of the mean score distribution. The rank of the United States (17th out of 79 countries) is above average in reading and average rank in mathematics (31st out of 79 countries) and science (23rd out of 79 countries). As Becker and Posner indicate, the relative performance of the United States should be evaluated with the consideration of cultural and demographic differences since the mean score of White and Asian students is significantly higher than the mean score of African American and Hispanic students. Disparities in mean scores between different demographic groups are typical in largely heterogenous populations. In Belgium, the regional disparity in mean scores between French and Flemish communities is even more striking. While the mean score in mathematics in 2006 in Flemish community had beenabove the OECD average, the mean score in mathematics of students in French community had been 18.56 points below the OECD average while the mean score of students in Flemish community had been 30 points above the OECD average. In 2009, such a relative difference would place French community in the rank of Italy, Portugal and Spain. On the other hand, student performance in Flemish-speaking community would reach the rank of Canada, Switzerland and Japan.
In the U.S, the demographic disparities in mean scores in reading, mathematics and science do not reflect the quality of the American education system. While the overall quality of the public and private American high school education system raised considerable concerns in previous performance of U.S. students in international mathematics and science ranking, the ranking of U.S. universities in science, mathematics and social sciences is the highest in the world. The output U.S. universities resulted in the highest number of Nobel laureates in physics, chemistry, medicine and economics as well as into cutting-edge accomplishments in R&D and technology. The emphasis on creativity and innovative thinking embodied in the American education system has enabled the United States to emerge as a world leader in technology, R&D, innovation and entrepreneurship.
The openness of the U.S. education system to international students, ideas and creative thinking could account for the remarkable achievements and academic quality of top American universities. On the other hand, poor teacher quality in American high school system is detrimental to the reading and quantitative literacy of American high school graduates, as a consequence of what Becker calls "teaching-to-the-test" syndrom where many public school teachers teach students topics not relevant to the command of knowledge but to the tests since test scores presumably determine teacher pay. Eric Hanushek of Hoover Institution recently found (link) that replacing bottom 5-8 percent of high school teachers with average teachers could near the United States on top of the international mathematics and science ranking. In addition, the measure is worth $100 trillion according to Hanushek (2010).
In the international perspective, student performance has been viewed as a significant determinant of the difference in cross-country economic performance. Recent paper by Atherton, Appleton and Bleaney (2010) found that higher mean test scores in mathematics, reading and science significantly improve per capita GDP. The authors showed that holding per capita income constant, average years of schooling is less important than mean test scores in predicting the economic growth. The 2009 PISA study highlighted the relationship between international test scores and economic growth. The evidence suggests almost non-existent correlation between reading performance and GDP per capita and cumulative education expenditure. The evidence simply suggests that socioeconomic variables matter more for reading performance than simple and often inconclusive aggregate indicators. In analysing the impact of various social and economic variables on reading performance, the results suggest a high correlation between parents' education and children's reading performance. For instance, 1 percentage point increase in the percentage of the population aged 35-44 with tertiary education returns 1.36 point increase in average reading performance where parents' education accounts for 44 percent of the variation in children's reading performance. The impact is shown in the following graph.
Source: OECD, PISA 2009.
A brief look also reveals another striking implication: cross-country reading performance is strongly affected by social and cultural status of the child's parents. A simple estimate of the relationship between reading performance and socio-economic status suggests that 1 percentage point increase in the share of students with very low social, cultural and economic status tends to decrease the average reading score by 1.13 points. Hence, social, economic and cultural status explains about 46 percent of the variation in student reading performance.
A considerable improvement of primary and secondary education system is vitally essential to the long-run economic growth. International test scores are an important method of evaluating international disparities in student performance and the subsequent impact on economic growth. Modern knowledge-driven economy requires not only intelligence, attentiveness but also comprehensive, integrated and developed social skills. Low reading, mathematics and science performance is generally attributed to student's low social, cultural and economic status. Genetic, cultural and socioeconomic variables, rather than education expenditure and GDP per capita, tend to play a major role in early childhood development as a basis of future student performance.
The economic and social future of countries requires considerable investment in children and student. Professor James Heckman of the University of Chicago brilliantly argued in Heckman equation (link) why the most gainful benefit of early childhood development is increased social productivity, greater motivation and developmental stimulation that every child needs. Our society should be not neglect an indisputable fact that early childhood development is a major determinant of student performance which sets the conditions for future advantage in school, college, career and life in general. Without these essential measures, student performance would suffer heavily from the spread of crime, teenage violence and high dropout rates.
The evidence from the 2009 PISA study suggests that higher quality of the education system is a necessary condition for higher test scores in reading, mathematics and science. As the evidence suggests, that the quality of human capital is strongly associated with higher standard of living. Without a prudent step towards improving developmental stimulation of students, considerably low student performance may seriously harm the prospects of future generations.
PISA test scores are aimed mainly at the evaluation of student knowledge at primary and secondary level in the fields of reading, mathematics and science. The assessment of knowledge in a particular field is subdivided into six different proficiency levels, ranging from 1 to 6. For instance, students at the 1st reading proficiency level are characterized by innate recognition of simple ideas reinforced in the text while students at the 6th reading proficiency level are characterized by a full capability of making multiple inferences, comparisons and contrasts and integrating the ideas presented in the text into a coherent conceptual framework of abstract ideas, sound evaluation and reflection. While 98.6 percent of OECD students can perform reading tasks at level 1, only 1.1 percent of students across OECD countries can perform reading tasks at the highest proficiency level. In addition, 28.4 percent of students in OECD countries exceeded the 4th (mid-range) reading proficiency level.
The reading scale has been further divided in reading continuous and non-continuous texts. However, the evidence suggest no systematic difference in reading scores between the two fields. Countries with the highest performance, measured as mean score, in reading rank are Korea (89.8 percent), Finland (89.3 percent) and Canada (87.3 percent). Countries with the largest student populations such as United States, United Kingdom and France were ranked in the upper-middle range while percent, and Israel (79 percent), Luxembourg (78.6 percent) and Austria (78.3 percent) are the lowest-ranking high-income countries on the reading scale in the 2009 PISA assessment. In the field of mathematics, 8 percent of students in OECD countries perform below level 1, 31.4 percent of students can perform mathematical tasks at 4th (mid-range) proficiency level while 3.1 percent of students perform at the highest proficiency level. In the country distribution, the percentage of students in the 6th proficiency level is the highest in Korea and Switzerland (8 percent), Japan, Belgium and New Zealand (5 percent). In a regional distribution, more than 25 percent of students in Shanghai perform at the highest level of mathematical proficiency. The proportion of students in the 6th proficiency level is very high in Singapore, Chinese Taipei and Hong Kong - 15.6 percent, 11.3 percent and 10.8 percent respectively. In addition, performance disparity in mathematics varied significantly across countries. Less than 1 percent of students in Mexico, Chile, Greece and Ireland reached 6th proficiency level A brief overview of the main empirical findings suggests a rather rigorous disparities in country ranking and performance.
The assessment of student performance in science is similar to the distribution of mean scores in the field of mathematics. About 5 percent of students perform below 1st proficiency level. In addition, only 29.4 percent of the students in OECD countries is proficient at 4th (mid-range) proficiency level in science while an average 1.1 percent of students in OECD countries can perform at the highest level of scientific literacy. In addition, the percentage of students below the lowest level of scientific proficiency is highly negatively correlated with country ranking since the proportion of students below the 1st level is the lowest in Finland (8.3 percent), Korea (6.3 percent), Estonia (8.3 percent) and Canada (9.6). Higher country ranking would thus indicate a lower proportion of students below the 1st proficiency level. All of the aforementioned countries ranked in the highest 10 percent of the distribution. If Shanghai, Hong Kong, Macao and Taipei were independent countries, their respective ranking in the field of scientific literacy would be in the top 10 percent of the distribution.
The empirical data on the distribution of mean scores in reading, mathematics and science are highly relevant to the measurement of human capital since the impact of mean scores on economic growth would differ to the certain extent from other measures of human capital. Recent attempts to capture the effect of human capital on economic growth were aimed at the definition of human capital as total years of primary, secondary and tertiary schooling. For instance, Robert Barro and Jong Wha Lee have collected disaggregated data on the total years of schooling for 146 countries between 1950 and 2005 at five-year intervals (link). The empirical evidence from the country panel suggests a strong linkage between schooling and long-run economic growth and institutional country features (link). In addition, Barro and Lee estimated the implicit return from an additional year of schooling ranging from 5 percent to 12 percent.
Gary Becker (link) and Richard Posner (link) recently discussed the 2009 PISA findings and the impact of cultural, genetic and demographic disparities on mean test scores in the United States. United States ranked in the middle of the mean score distribution. The rank of the United States (17th out of 79 countries) is above average in reading and average rank in mathematics (31st out of 79 countries) and science (23rd out of 79 countries). As Becker and Posner indicate, the relative performance of the United States should be evaluated with the consideration of cultural and demographic differences since the mean score of White and Asian students is significantly higher than the mean score of African American and Hispanic students. Disparities in mean scores between different demographic groups are typical in largely heterogenous populations. In Belgium, the regional disparity in mean scores between French and Flemish communities is even more striking. While the mean score in mathematics in 2006 in Flemish community had beenabove the OECD average, the mean score in mathematics of students in French community had been 18.56 points below the OECD average while the mean score of students in Flemish community had been 30 points above the OECD average. In 2009, such a relative difference would place French community in the rank of Italy, Portugal and Spain. On the other hand, student performance in Flemish-speaking community would reach the rank of Canada, Switzerland and Japan.
In the U.S, the demographic disparities in mean scores in reading, mathematics and science do not reflect the quality of the American education system. While the overall quality of the public and private American high school education system raised considerable concerns in previous performance of U.S. students in international mathematics and science ranking, the ranking of U.S. universities in science, mathematics and social sciences is the highest in the world. The output U.S. universities resulted in the highest number of Nobel laureates in physics, chemistry, medicine and economics as well as into cutting-edge accomplishments in R&D and technology. The emphasis on creativity and innovative thinking embodied in the American education system has enabled the United States to emerge as a world leader in technology, R&D, innovation and entrepreneurship.
The openness of the U.S. education system to international students, ideas and creative thinking could account for the remarkable achievements and academic quality of top American universities. On the other hand, poor teacher quality in American high school system is detrimental to the reading and quantitative literacy of American high school graduates, as a consequence of what Becker calls "teaching-to-the-test" syndrom where many public school teachers teach students topics not relevant to the command of knowledge but to the tests since test scores presumably determine teacher pay. Eric Hanushek of Hoover Institution recently found (link) that replacing bottom 5-8 percent of high school teachers with average teachers could near the United States on top of the international mathematics and science ranking. In addition, the measure is worth $100 trillion according to Hanushek (2010).
In the international perspective, student performance has been viewed as a significant determinant of the difference in cross-country economic performance. Recent paper by Atherton, Appleton and Bleaney (2010) found that higher mean test scores in mathematics, reading and science significantly improve per capita GDP. The authors showed that holding per capita income constant, average years of schooling is less important than mean test scores in predicting the economic growth. The 2009 PISA study highlighted the relationship between international test scores and economic growth. The evidence suggests almost non-existent correlation between reading performance and GDP per capita and cumulative education expenditure. The evidence simply suggests that socioeconomic variables matter more for reading performance than simple and often inconclusive aggregate indicators. In analysing the impact of various social and economic variables on reading performance, the results suggest a high correlation between parents' education and children's reading performance. For instance, 1 percentage point increase in the percentage of the population aged 35-44 with tertiary education returns 1.36 point increase in average reading performance where parents' education accounts for 44 percent of the variation in children's reading performance. The impact is shown in the following graph.
Parents' education and student reading performance

A brief look also reveals another striking implication: cross-country reading performance is strongly affected by social and cultural status of the child's parents. A simple estimate of the relationship between reading performance and socio-economic status suggests that 1 percentage point increase in the share of students with very low social, cultural and economic status tends to decrease the average reading score by 1.13 points. Hence, social, economic and cultural status explains about 46 percent of the variation in student reading performance.
A considerable improvement of primary and secondary education system is vitally essential to the long-run economic growth. International test scores are an important method of evaluating international disparities in student performance and the subsequent impact on economic growth. Modern knowledge-driven economy requires not only intelligence, attentiveness but also comprehensive, integrated and developed social skills. Low reading, mathematics and science performance is generally attributed to student's low social, cultural and economic status. Genetic, cultural and socioeconomic variables, rather than education expenditure and GDP per capita, tend to play a major role in early childhood development as a basis of future student performance.
The economic and social future of countries requires considerable investment in children and student. Professor James Heckman of the University of Chicago brilliantly argued in Heckman equation (link) why the most gainful benefit of early childhood development is increased social productivity, greater motivation and developmental stimulation that every child needs. Our society should be not neglect an indisputable fact that early childhood development is a major determinant of student performance which sets the conditions for future advantage in school, college, career and life in general. Without these essential measures, student performance would suffer heavily from the spread of crime, teenage violence and high dropout rates.
The evidence from the 2009 PISA study suggests that higher quality of the education system is a necessary condition for higher test scores in reading, mathematics and science. As the evidence suggests, that the quality of human capital is strongly associated with higher standard of living. Without a prudent step towards improving developmental stimulation of students, considerably low student performance may seriously harm the prospects of future generations.

Religion and economic growth
In the course of economic growth theory, the impact of religion on economic growth and GDP per capita has been largely neglected by the mainstream economic theory. Basically, there have been two major conceptual forces behind the demonstration of the effect of religiousness on economic growth. First, traditional theoretical approach to the analysis of economic growth embodied in the Solow approach emphasized the role of capital accumulation and technological progress in the growth of total factor productivity where the technological progress accounted for the unexplained and exogenous feature that drove the growth of total factor productivity.
Early analyses of economic growth and its main determinants heavily neglected the effect of institutional variables on economic growth. Second, the theoretical framework of economic growth usually follows the empirical evidence on the existence of postulated hypotheses related to the economic growth. Primarily, the effect of religion and other institutional features on economic growth has been displaced to the lack of empirical estimation techniques that could account and control for the effect of the institutional phenomena on the course of economic growth.
The best lucrative and empirically consistent analysis of economic growth and its determinants had been documented by Robert Barro and Xavier Sala-i-Martin. In 2004, Robert Barro published Economic Growth Across Countries. In the explanatory framework, the author included several institutional variables and examined its effect on 10-year economic growth interval in a cross section of 86 countries over 1965-1975, 1975-1985 and 1985-1995 time periods. For a given set of institutional control variables, the rule of law exerted a strong, positive and statistically significant effect on growth. The effect of democracy, the second institutional control variable, was estimated by a single coefficient and its squared term to account for a possible movement of the effect of the level of democracy.
The magnitude of both coefficients was statistically significant. The sign of the squared term was negative suggesting for a typical inverted-U effect of democracy on economic growth. In the meaning of the economic theory, the estimated coefficients suggested that the adoption of democratic institutions and policies in the initial stage of GDP per capita boosts economic growth, particularly by the institutions such as the rule of law, electoral representation, and multiparty political system as well as by the constitutional protection of civil liberties.
However, as countries depart from the initial level of GDP per capita, the political pressure from electoral representation tends to enforce egalitarian policies that negatively effect economic growth, particularly by the fiscal redistribution of income to mitigate income inequality. Consequently, the effect of democratic institutions tends to diminish and, as the curve bends, the predictive effect of constitutional democracy is negative, thereby exerting a negative effect on economic growth. However, the hypothetical relationship between democracy and economic growth is dubious, if not intriguing. In fact, neoclassical growth theories suggest that the rate of economic growth tends to diminish alongside the expansion of the capital stock and productive capacity of the national economy. The hypothesized theoretical assertion postulates that the non-linear, inverted-U effect of democratic institutions on economic growth is overestimated.
In 2003, Robert Barro and Rachel M. McCleary wrote a seminal contribution (link) to the theory and empirics of the relationship between religion and economic growth. Even though in The Protestant Ethics, Max Weber argued that the religious practices and beliefs have had important implications for economic development, the economists paid little or no attention to the role of religiousness as a cultural measure on economic growth. Arguably, the most difficult inferential problem in economic theory is to capture the direction of causality in non-experimental data which indistinguishably confuses the empirical inference from sample estimates. The theoretical relationship between the religion and economic growth is nonetheless a daunting task of the economic theory.
Across the world, there is a whole spectrum of religious diversity in the interplay between religion and economic development. Some countries, such as the United States have been largely influenced by the Enlightenment thought, penned in Thomas Jefferson’s 1779 The Virginia Act for Establishing Religious Freedom, on religious freedom as the principle of freedom from religious oppression. On the other hand, countries in Northern and some parts of the Continental Europe largely adopted Protestantism as the religious establishment while Southern and Central European countries experienced a strong and coercive influence of Roman Catholicism. Hence, the historical bond of nations in the Middle East and North Africa to the Islamic religion accounts for a significant share of the world population and a representative estimate of the effect of Islam on economic growth.
In addition, many political regimes, particularly in China, Soviet Union and Cuba, have attempted to suppress the religious freedom and, hence, establish a system that officially prohibited and punished the religious practice. Surprisingly, countries in Northern Europe such as Norway, Finland and Iceland have established an official religion that is effectively articled in the constitution. Given the vast difference in the distribution of GDP per capita across countries, the assessment of the relationship between the religion and economic growth is not a triviality per se.
Robert Barro and Rachel M. McCleary constructed a broad cross-country dataset which included national account variables and an array of other political, economic and institutional indicators in a cross section of over 100 countries since 1960. The predicted theoretical expectations postulate whether the religion fosters religious beliefs that influence individual cultural characteristics such as ethics, work and honesty. The authors estimated both the effect of different explanatory variables on religious outcomes such as monthly church attendance, the belief in heaven and the belief in hell.
The estimated coefficients suggest that monthly church attendance is strongly affected by urbanization rate and a set of dichotomous religious variables. In particular, a one percentage point increase in the urbanization rate decreases monthly church attendance rate by 1.49 percentage points, holding all other factors constant. In addition, a 1 percentage point increase in religious pluralism fosters the monthly church attendance rate by 1.35 percentage points, ceteris paribus, while the increase in the measure of the regulation of religion by 1 percentage point decreases the church attendance rate by 0.64 percentage point. Hence, the church attendance rate in countries with official state religion, on average, increases the religious participation by 0.87 percent more compared to countries with the absence of state religion, ceteris paribus. The belief in heaven and hell, on the other hand, is positively correlated with state religion and religious pluralism, Muslim religious faction and other religious factions. The belief in heaven and hell is significantly negatively correlated with urbanization rate, communist regimes, Orthodox religion, Hindu religion and Protestant religion. Barro and McCleary regressed growth rates of real GDP per capita on variables of monthly church attendance rate, belief in heaven, belief in hell and dichotomous (dummy) religious variables representing the share of religion in the countries observed. The table below reports dummy coefficients of each religion relative to the Roman Catholicism. The sign of the coefficient is negative suggesting the increase in the share of each religion (see table) decreases the growth rate of real GDP per capita by less than by the anticipated increase in the share of Roman Catholic religion.

The effect of religion on long-run economic growth

Source: R. Barro & R.M. McCleary: Religion and Economic Growth, 2003.The p-value for religion shares in the regression specification is about 0.001, suggesting that the hypothetical zero simultaneous effect of the explanatory dummy variables of religious share is easily rejected at 0.1 percent level of statistical significance. The estimate suggests that religious shares influence the growth rate of real GDP per capita. Interestingly, sample estimates of regression coefficients suggest that monthly church attendance is significantly negatively related to the GDP growth rate. The estimated coefficient suggests that higher church attendance will, on average, lead to significantly lower growth rate of real GDP per capita and, hence, a lower growth of the standard of living. On the other hand, the sample estimates of growth regression coefficients suggest that the extent of belief in heaven and hell is positively related to economic growth. Thus, the empirical evidence from the panel of over 100 countries since 1960 suggests that the belief in heaven and hell encourage ethical behavior and honesty and thereby simultaneously increases the growth rate of real GDP per capita. The reported p-value for church attendance and beliefs is 0.000, suggesting the rejection of null hypothesis on a simultaneous zero effect of church attendance and beliefs in hell and heaven on the growth rate of real GDP per capita, and a strong influence of religious factors on the distribution of economic growth across countries since 1960.
Regarding the true importance of religious freedom, not oppression, on the emergence of order alongside the abstract rules and the pursuit of individual liberty, Friedrich August von Hayek wrote in The Constitution of Liberty: “It should be remembered that, so far as men’s actions toward other persons are concerned, freedom can never mean more that they are restricted only by the general rules. Since there is no kind of action that may not interfere with another person’s protected sphere, neither speech, nor the press, nor the exercise of religion can be completely free. In all these fields … freedom does mean and can mean only that what we may do is not dependent on the approval of any person or authority and is limited only by the same abstract rules that apply equally to all.”
In the microeconomic perspective, religious market is highly oligopolistic, especially in Europe where government subsidies to large religious groups discourage the entry of competitive religions in the market. Therefore, in strongly Catholic countries, such as Italy and Spain, Roman Catholic church firmly resembles the behavioral pattern of a dominant firm, facing price inelastic demand and price elastic supply. Subsidies to churches do not quite differ from subsidies to corporations and enterprises - the net effect are lower marginal costs, increasing the total producer surplus of the church and increasing the deadweight loss to the consumers of religious services. A cautionary approach would require not only the precise modeling of the religious market upon the theoretical assumptions but also the contestable empirical evidence on the existence of the Catholic church as a dominant firm in highly oligopolistic religious market.
Incidentally, the empirical evidence suggests strongly negative effect of the share of Roman Catholic religion on the long-run growth rate of real GDP per capita. Nonetheless, religion is an important determinant of economic growth. However, the evidence from the second half of the last century suggests that the prosperity and wealth of nations is greater if people allocate fewer resources to the exercise of religious activities.
