government impartiality and sustained growth in sub saharan africa many studies suggest that one of the main reasons for africa s dismal growth performance over most of the 20th century is its degree of ethnic fragmentation yet there is still insufficient knowledge about whether ethnic diversity necessarily entails large economic costs or whether the implications of diversity depend inter alia on the government s approach toward the ethnic question we note that economic growth tends to increase average incomes but it also affects the income distribution then if growth is accompanied by growing economic inequality the perception of the impartiality of the government toward different ethnic groups is likely to be important for whether growth can be sustained or whether sparks of growth will evaporate because of rising political divisions and internal conflicts in this paper we study whether the degree of ethnic impartiality in the government s policies is related to the emergence of sustained growth in sub saharan africa irrespective of the actual content of the policies we measure perceptions about the impartiality of the government with survey data from the afrobarometer covering 20 countries starting in the late 1990 s our main definition of sustained growth is when there is a gdp per capita growth rate of at least 2 for at least five consecutive years our empirical results suggest that countries whose governments are perceived as impartial are more likely to experience sustained growth we conclude that in order to ensure economic development it is not only important to choose the right policies but also to implement these policies in a fair manner

ethnic inequality and poverty in malaysia since may 1969 part 1 inequality abstract the race riots that broke out in kuala lumpur in may 1969 triggered a national public effort to greatly reduce both malaysia s longstanding ethnic inequalities and its high incidence of poverty this paper studies how various measures of ethnic inequality evolved since 1969 two conceptual distinctions are emphasized that between income inequality and polarization on the one hand and that between relative and absolute inequality on the other over the last 50 years the poorest ethnic group the bumiputera have had the highest growth rate of household incomes which helped assure a substantial long term decline in relative between group inequality which in turn substantially reduced overall income inequality measures of ethnic polarization moved highly synchronously with between group inequality the differential growth rates by ethnicity were not enough to prevent rising absolute inequality given the extent of the initial ethnic disparities despite the progress against relative inequality malaysia s absolute disparities by ethnicity are now even larger than 50 years ago the second paper of this two part paper examines the contribution of lower relative ethnic inequality to the country s progress against poverty

on the dynamics of ethnic fractionalization does fractionalization change over short periods of time if so are there any substantial implications for economic performance to answer such questions we construct a new panel data set with measures of ethnic linguistic and religious fractionalization for 26 former communist countries covering the period from 1989 to 2002 our fractionalization measures show that transition economies became more ethnically homogeneous over such a short period of time although the same did not happen for linguistic and religious diversity in line with the most recent literature there seems to be no effect of exogenous diversity on macroeconomic performance that is on per capita gdp growth however we find that dynamic endogenous ethnic diversity is negatively related to growth although this is still not the case for linguistic and religious diversity these findings are robust to different specifications polarization measures and instrument sets as well as to a composite index of ethnic linguistic religious fractionalization

migration diversity and economic growth when migrants move from one country to another they carry a new range of skills and perspectives which nurture technological innovation and stimulate economic growth at the same time increased heterogeneity may undermine social cohesion create coordination and communication barriers and adversely affect economic development in this article we investigate the extent to which cultural diversity affects economic growth and whether this relation depends on the level of development of a country we use novel data on bilateral migration stocks that is the number of people living and working outside the countries of their birth over the period 1960 2010 and compute indices of fractionalization and polarization in so doing we explore the effect of immigration on development through its effect on the composition of the destination country we find that overall both indices have a distinct positive impact on real gdp per capita and that the effect of diversity seems to be more consistent in developing countries

religious adherence and county economic growth in the us abstract we estimate a barro type conditional convergence model using religious adherence data from the american religious data archive to analyze independent effects of church adherence rates on economic growth in the united states at the county level per capita income growth is modeled as a function of initial per capita income initial human capital stock and a set of control and related variables including religious adherence religious diversity and regional indicator variables we also investigate the independent effects of three main denominations namely catholics evangelical christians and mainline christians on county economic growth our results indicate that the religious adherence in general is significantly greater than zero and not beneficial for us county income growth we find mixed results for effects of various denominations

environmental performance in socially fragmented countries social fragmentation is often associated with reduced co operative behaviour which undermines public goods provision such as environmental protection the few studies linking social fragmentation and environmental performance have been confined to using ethnic fractionalisation as the only measure of social heterogeneity in this paper we contribute to the literature in a twofold manner first we bring into the analysis alternative measures of social fragmentation i e religious fractionalisation ethnic religious polarisation that have received considerable attention in development economics in recent years second this is the first study to our knowledge that makes use of a large panel dataset of several environmental indicators to explore links between ethnic religious diversity and the environment we find that all indices of social fragmentation are negatively linked to measures of environmental quality although for some of them the size of the effect is larger in the case of polarisation

religious polarization and economic development abstract this paper analyzes the effect of religious diversity on economic development we argue that the religious polarization index is more appropriate to measure the effect of potential conflict on economic development than the traditional fragmentation index the empirical exercises support this view

ethnic diversity and economic development abstract this paper analyzes the role that different indices and dimensions of ethnicity play in the process of economic development firstly we discuss the advantages and disadvantages of alternative data sources for the construction of indices of religious and ethnic heterogeneity secondly we compare the index of fractionalization and the index of polarization we argue that an index of the family of discrete polarization measures is the adequate indicator to measure potential conflict we find that ethnic religious polarization has a large and negative effect on economic development through the reduction of investment and the increase of government consumption and the probability of a civil conflict

can democracy help growth and ethnic divisions this paper presents further empirical evidence suggestive of democracy s positive role in ameliorating the negative growth effects of ethnic diversity in nations however it is shown that endogeneity problems and a direct negative growth effect of democracy place inherent limitations on the strength of policy implications which may be drawn from the evidence

the size and scope of government comparative politics with rational politicians we try to demonstrate how economists may engage in research on comparative politics relating the size and composition of government spending to the political system a downsian model of electoral competition and forward looking voting indicates that majoritarian as opposed to proportional elections increase competition between parties by focusing it into some key marginal districts this leads to less public goods less rents for politicians more redistribution and larger government a model of legislative bargaining and backward looking voting indicates that presidential as opposed to parliamentary regimes increase competition between both politicians and voters this leads to less public goods less rents for politicians less redistribution and smaller government we confront these predictions with cross country data from around 1990 controlling for economic and social determinants of government spending we nd strong and robust support for the prediction that the size of government is smaller under presidential regimes and weaker support for the prediction that majoritarian elections are associated with less public goods

ethnic diversity and social capital in indonesia this paper uses the variations of ethnic diversity between districts in indonesia to show that diversity leads to lower social capital outcomes i find that distinguishing between ethnic polarization and fractionalization matters for the results as polarization has a larger negative effect the results cannot entirely be attributed to selection on unobservables and at least part of the relationship should be interpreted as causal finally diversity seems to increase tolerance despite its negative effect on other social capital variables such as trust perceived safety and participation to community activities and voting in elections

religiosity and the cost of debt abstract in a cross country setting we document that stronger religiosity is associated with lower loan interest spread in addition we show that this negative association is more pronounced in countries with weaker creditor rights suggesting that religious values play a more significant role in constraining opportunistic behavior in a weaker legal environment our analysis reveals that stronger religiosity is also related to other favorable terms in loan contracting such as larger facility amount use of accounting based performance pricing and lower upfront fee corroborating our cross country findings we also show that in the u s setting firms in regions with stronger religiosity enjoy lower loan interest spread our study contributes to understanding the important role religiosity plays in debt financing

electoral systems and public spending we study the effects of electoral institutions on the size and composition of public expenditure in oecd and latin american countries we emphasize the distinction between purchases of goods and services which are easier to target geographically and transfers which are easier to target across social groups we present a theoretical model in which voters anticipating government policymaking under different electoral systems have an incentive to elect representatives more prone to transfer public good spending in proportional majoritarian systems the model also predicts higher total primary spending in proportional majoritarian systems when the share of transfer spending is high low after dee ning rigorous measures of proportionality to be used in the empirical investigation we e nd considerable support for our predictions

a note on optimal ordering policies in response to a discount offer abstract in this short note we are suggesting a marginal analysis approach over the approach used by sarker and al kindi 2006 optimal ordering policies in response to a discount offer international journal of production economics 100 2 195 211 for developing models for determining the optimal ordering policy for an item for which the supplies offer a price discount during a sale period

conflict and distribution abstract we develop a behavioral model that links the level and pattern of social conflict to the societywide distribution of individual characteristics the model can be applied to groups that differ in characteristics such as wealth ethnicity religion and political ideology we settle questions of existence and uniqueness of conflict equilibrium conflict is seen to be closely connected with the bimodality of the underlying distribution of characteristics however in general the conflict distribution relationship is nonlinear and surprisingly complex our results on conflict patterns also throw light on the phenomena of extremism and moderation journal of economic literature classification numbers d63 d72 d74

linking conflict to inequality and polarization in this paper we study a behavioral model of conflict that provides a basis for choosing certain indices of dispersion as indicators for conflict we show that a suitable monotone transform of the equilibrium level of conflict can be proxied by a linear function of the gini coefficient the herfindahl hirschman fractionalization index and a specific measure of polarization due to esteban and ray jel classification d74 d31

poverty and civil war revisiting the evidence abstract previous research has interpreted the correlation between per capita income and civil war as evidence that poverty is a main determinant of conflict in this paper we find that the relationship between poverty and civil war is spurious and is accounted for by historical phenomena that jointly determine income evolution and conflict in particular the statistical association between poverty and civil wars disappears once we include country fixed effects also using cross section data for 1960 to 2000 we find that once historical variables like european settler mortality rates and the population density in 1500 are included in civil war regressions poverty does not have an effect on civil wars these results are confirmed using longer time series from 1825 to 2000

the trade facilitation impact of the chinese diaspora using an enhanced data set on the population share of overseas chinese in 1970 and 1990 this paper analyses the impact of the chinese diaspora on facilitating china s bilateral trade during the period 1973 2013 our findings suggest substantial trade creation effects resulting from the presence of ethnic chinese in the trade partner population diaspora impacts on chinese bilateral imports are in general higher than those found for exports coethnic networks play a larger role as long as the partner country does not have an rta with china in place among export sectors effects found were strongest for food as well as for machinery and transport equipment in regard to imports coethnic networks matter mostly for raw materials machinery and transport equipment and chemicals

cultural diversity and economic growth evidence from the us during the age of mass migration we exploit the large inflow of immigrants to the us during the 1870 1920 period to examine the effects that within county changes in the cultural composition of the us population had on output growth we construct measures of fractionalization and polarization to distinguish between the different effects of cultural diversity our main finding is that increases in cultural fractionalization significantly increased output while increases in cultural polarization significantly decreased output we address the issue of identifying the causal effects of cultural diversity by using the supply push component of immigrant inflows as an instrumental variable

how democracy affects growth abstract this paper introduces a new methodology to examine the empirical relationship between democracy and economic growth democratic institutions are assumed to affect growth through a series of channels we specify and estimate a full system of equations determining growth and the channel variables results suggest that democracy fosters growth by improving the accumulation of human capital and less robustly by lowering income inequality on the other hand democracy hinders growth by reducing the rate of physical capital accumulation and less robustly by raising the ratio of government consumption to gdp once all of these indirect effects are accounted for the overall effect of democracy on economic growth is moderately negative our results indicate that democratic institutions are responsive to the demands of the poor by expanding access to education and lowering income inequality but do so at the expense of physical capital accumulation

openness and income the roles of trade and migration abstract this paper explores the relationship between openness to trade immigration and income per person across countries to address endogeneity concerns we extend the instrumental variables strategy introduced by frankel and romer 1999 we build predictors of openness to immigration and to trade for each country by using information on bilateral geographical and cultural distance while controlling for country size since geography may affect income through other channels we also control for climate disease environment natural resources and colonial origins most importantly we also account for the roles of institutions and early development our instrumental variables estimates provide evidence of a robust positive effect of openness to immigration on long run income per capita in contrast we are unable to establish an effect of trade openness on income we also show that the effect of migration operates through an increase in total factor productivity which appears to reflect increased diversity in productive skills and to some extent a higher rate of innovation

the role of ethnic diversity in sustainable environmental growth new evidence across different income regions we examine the relationship between ethnic diversity and environmental quality proxied by carbon dioxide formula presented emissions ethnic diversity is captured using indices of ethnic fractionalization adopting a supply demand framework which introduces a model for economic growth we find that ethnic fractionalization reduces formula presented emissions the negative effect of ethnic diversity on formula presented emissions is also consistent across middle and low income countries as well as high income countries however results suggest that ethnic diversity has a negative effect on growth in middle and low income countries but a positive effect on growth in high income countries our findings prove robust to alternative estimation methods

barriers to investment in polarized societies i present a tractable dynamic model of political economy where disagreements about the composition of public spending result in implementation of short sighted policies the relative price of investment to consumption is excessively large in equilibrium due to over taxation investment rates are too low which slows down growth along the transition in the long run this results in output consumption and welfare being inefficiently low the larger is the degree of polarization the greater is the inefficiency political stability mitigates the effects of polarization by making the incumbent internalize the dynamic inefficiencies introduced by the choice of growth retarding policies

respect responsibility and development abstract we develop a theory that explains how two core values respect for others and responsibility affect productivity the accumulation of capital and output per worker using data from the world values survey we empirically test the model using a panel dataset that includes 82 countries over six distinct years we find that these two core values are important to production and that their impact is substantial we also show that respect and responsibility reduce the influence of trust and mitigate the negative macroeconomic effects associated with fractionalized societies our results are robust to various treatments for endogeneity and under alternative samples

the multidimensional effects of religion on socioeconomic development a review of the empirical literature religion plays a fundamental role in most people s lives with profound implications for socioeconomic development this survey provides a comprehensive and systematic overview of the causal mechanisms between religion and development discussed and tested in the economics literature and reviews quantitative empirical evidence on the actual effects of religion on economic and social dimensions of development we start by disaggregating the concept of religion into four religious dimensions and propose a framework to conceptualize causal mechanisms numerous mechanisms are possible but only a few uncontested findings exist religion is ambivalent vis a vis development although religious ideas can foster certain forms of human capital acquisition and labor market participation scholars have found a negative relationship between religious dimensions and both income and gender equality as well as innovation activities religious identity is also a source of labor market discrimination and has ambivalent effects on economic growth and social cohesion methodological challenges refer to the availability of fine grained data especially for developing countries the use of concepts and definitions and the lack of causal inference

how ethnic diversity affects economic growth summary this paper investigates the empirical relationship between ethnic diversity polarization and economic growth ethnicity is assumed to affect economic growth through a number of possible transmission channels that are generally included in cross country growth regressions this paper provides an extensive empirical analysis shedding light on the various sources through which ethnic diversity and polarization affects economic growth indirectly it advances and empirically establishes the hypothesis that ethnic diversity has a strong direct negative impact on economic growth whereas ethnic polarization has non negligible indirect economic effects through the specified channel variables

commodity windfalls polarization and net foreign assets panel data evidence on the voracity effect this paper examines the effects that windfalls from international commodity price booms have on net foreign assets in a panel of 145 countries during the period 1970 2007 the main finding is that windfalls from international commodity price booms lead to a significant increase in net foreign assets but only in countries that are ethnically homogeneous in highly ethnically polarized countries net foreign assets significantly decreased to explain this asymmetry the paper shows that in ethnically polarized countries commodity windfalls lead to large increases in government consumption expenditures and political corruption the paper s findings are consistent with theoretical models of the current account that have a built in voracity effect
