the political economy of linguistic cleavages article i nfo this paper uses a linguistic tree describing the genealogical relationship between all 6912 world languages to compute measures of diversity at different levels of linguistic aggregation by doing so we let the data inform us on which linguistic cleavages are most relevant for a range of political economy outcomes rather than making ad hoc choices we find that deep cleavages originating thousands of years ago lead to better predictors of civil conflict and redistribution the opposite pattern emerges when it comes to the impact of linguistic diversity on growth and public goods provision where finer distinctions between languages matter 2011 elsevier b v all rights reserved

bounds on elasticities with optimization frictions a synthesis of micro and macro evidence on labor supply how can price elasticities be identified when agents face optimization frictions such as adjustment costs or inattention i derive bounds on structural price elasticities that are a function of the observed effect of a price change on demand the size of the price change and the degree of frictions the degree of frictions is measured by the utility losses agents tolerate to deviate from the frictionless optimum the bounds imply that frictions affect intensive margin elasticities much more than extensive margin elasticities i apply these bounds to the literature on labor supply the utility costs of ignoring the tax changes used to identify intensive margin labor supply elasticities are typically less than 1 of earnings as a result small frictions can explain the differences between micro and macro elasticities extensive and intensive margin elasticities and other disparate findings pooling estimates from existing studies i estimate a hicksian labor supply elasticity of 0 33 on the intensive margin and 0 25 on the extensive margin after accounting for frictions

global inequality of opportunity how much of our income is determined by where we live suppose that all people in the world are allocated only two characteristics over which they have almost no control country of residence and income distribution within that country assume further that there is no migration the authors show that more than one half of variability in income of world population classified according to their household per capita in one percent income groups by country is accounted for by these two characteristics the role of effort or luck cannot play a large role in explaining global distribution of income

optimal migration a world perspective we ask what level of migration would maximize world welfare welfare is assumed to be a weighted average of the utilities of the world s various citizens but the weights are also country specific using a calibrated one sector model we find that unless the weights are heavily biased toward the natives of rich countries the extent of migration that would be optimal far exceeds the levels observed today the claim remains true in a two sector extension of the model all versions of the model assume that migration is the only redistributive tool

the openness equality trade off in global redistribution the gulf cooperation council gcc countries accept massive numbers of migrants from poor countries and pay wages that dramatically improve over outside options but are meagre by the standards of natives as such they do dramatically more per capita to reduce global inequality than do the fortress welfare states of the organisation for economic cooperation and development oecd countries if oecd countries were to imitate the gcc it would reduce global inequality by more than full equalisation within the oecd would such examples suggest a philosophically disturbing trade off between openness to global inequality reducing migration and internal equality

aid effectiveness the role of the local elite we study the importance of the local elite as a determinant of the effectiveness of foreign aid in developing countries the local elite serves as an intermediary between aid donors and aid recipients through its control of the government and major firms the likelihood of misusing aid is large if the elite is characterized by extensive economic and political power and little concern for social groups besides itself to determine which countries have this type of elite we use a historically determined variable the percentage of european settlers in total population in colonial times we provide strong empirical evidence that the level of european settlement in colonial times is negatively related to the effectiveness of foreign aid as measured in a growth regression framework our results are robust to the inclusion of a wide set of alternative explanatory factors advanced in the aid effectiveness literature

the fiscal effects of immigration to the uk we investigate the fiscal impact of immigration on the uk economy with a focus on the period since 1995 our findings indicate that when considering the resident immigrant population in each year from 1995 to 2011 immigrants from the european economic area eea have made a positive fiscal contribution even during periods when the uk was running budget deficits while non eea immigrants not dissimilar to natives have made a negative contribution for immigrants that arrived since 2000 contributions have been positive throughout and particularly so for immigrants from eea countries notable is the strong positive contribution made by immigrants from countries that joined the eu in 2004

the limitations of decentralized world redistribution an optimal taxation approach abstract a centralized scheme of world redistribution that maximizes a border neutral social welfare function subject to the disincentive effects it would create generates a drastic reduction in world consumption inequality dropping the gini coefficient from 0 69 to 0 25 in contrast an optimal decentralized i e with no cross country transfers redistribution has a miniscule effect on world income inequality thus the traditional public finance concern about the excess burden of redistribution cannot explain why there is so little world redistribution actual foreign aid is vastly lower than the transfers under the simulated world income tax suggesting that voluntary world transfers subject to a free rider problem produces an outcome that is consistent with rich countries such as the united states either placing a much lower value on the welfare of foreigners or else expecting that a very significant fraction of cross border transfers is wasted the product of the welfare weight and one minus the share of transfers that are wasted constitutes the implicit weight that the united states assigns to foreigners we calculate that value to be as low as 1 2000 of the value put on the welfare of an american suggesting that u s policy is consistent with social preferences that place essentially no value on the welfare of the citizens of the poorest countries or that implicitly assumes that essentially all transfers are wasted

are left wing party strength and corporatism good for the environment evidence from panel analysis of air pollution in oecd countries abstract the effect of left wing party strength and corporatism on air pollution levels in up to 21 oecd countries over the period 1980 or 1990 1999 is tested with both fixed effects and random effects estimators controlling for scale composition technique as well as aggregate time effects robust evidence is found that parliamentary green left libertarian party strength is associated with lower pollution levels the rise of ecologically oriented parties has thus had a real impact on air pollution levels traditional left wing party strength is possibly also associated with lower pollution levels but the evidence is less consistent and robust combined left wing party strength in government is possibly associated with higher pollution levels but this result is also far from robust and is practically small no evidence is found for a consistent systematic impact of corporatism on pollution levels

aid dependence and the quality of governance cross country empirical tests aid dependence can potentially undermine the quality of governance and public sector institutions by weakening accountability encouraging rent seeking and corruption fomenting conflict over control of aid funds siphoning off scarce talent from the bureaucracy and alleviating pressures to reform inefficient policies and institutions analyses of cross country data in this paper provide evidence that higher aid levels erode the quality of governance as measured by indices of bureaucratic quality corruption and the rule of law these findings support the need for donors to develop less costly and less intrusive ways of disseminating state of the art knowledge on public sector reform in developing countries

the world distribution of income falling poverty and convergence period we estimate the world distribution of income by integrating individual income distributions for 138 countries between 1970 and 2000 country distributions are constructed by combining national accounts gdp per capita to anchor the mean with survey data to pin down the dispersion poverty rates and head counts are reported for four specific poverty lines rates in 2000 were between one third and one half of what they were in 1970 for all four lines there were between 250 and 500 million fewer poor in 2000 than in 1970 we estimate eight indexes of income inequality implied by our world distribution of income all of them show reductions in global inequality during the 1980s and 1990s

on the political economy of immigration and income redistribution in this article we analyze an economy in which agents vote over immigration policy and redistributive tax policy we show that natives preferences over immigration are influenced by the prospect that immigrants will be voting over future tax policy we also show that changes in the degree of international capital mobility the distribution of initial capital among natives the wealth or poverty of the immigrant pool and the future voting rights and entitlements of immigrants can have dramatic effects on equilibrium immigration and tax policies finally we provide some empirical support for the model s predictions

the limits of equality insights from the israeli kibbutz what limits the capacity of society to redistribute what determines the structure of compensation in organizations striving for income equality this paper addresses these questions by investigating the economic and sociological forces underlying the persistence of the israeli kibbutzim communities based on the principle of income equality to do this i exploit newly assembled data on kibbutzim and a financial crisis in the late 1980s that affected them differentially the main findings are that 1 productive individuals are the most likely to exit and a kibbutz s wealth serves as a lock in device that increases the value of staying 2 higher wealth reduces exit and supports a high degree of income equality and 3 ideology facilitates income equality using a simple model i show that these findings are consistent with a view of the kibbutz as providing optimal insurance when members have the option of leaving more generally these findings contribute to an understanding of how mobility limits redistribution and to an understanding of the determinants of the sharing rule in other types of organizations such as professional partnerships cooperatives and labor managed firms

the influence of south korean energy policy on opec oil exports abstract south korea is the fifth top oil importer worldwide with 64 of its oil coming from opec member countries over the last 30 years south korea accounted for a rapid increase in energy use this in turn led south korea to be totally dependent on oil imports due to this increase south korea has been experiencing drastic changes in its energy system which could potentially impact its dependence on opec oil import external and internal factors have forced south korea to change its energy strategy and targets these targets would be achieved by reducing its energy intensity and utilizing electricity and renewable energies in order to reduce its dependence on oil consumption low carbon green growth is one policy along with many other energy policies developed by south korea for reducing greenhouse gases thus this policy is receiving a remarkable attention today these national policies along with other international ones are needed to mitigate greenhouse gas emissions and promote other green initiatives this study puts emphasis on these policies as well as uses them to predict the future energy profile of south korea and how these policies will impact on oil imports from opec member countries

do concerns about labor market competition shape attitudes toward immigration new evidence abstract are concerns about labor market competition a powerful source of anti immigrant sentiment several prominent studies have examined survey data on voters and concluded that fears about the negative effects of immigration on wages and employment play a major role generating anti immigrant attitudes we examine new data from a targeted survey of u s employees in 12 different industries in contrast with previous studies the findings indicate that fears about labor market competition do not appear to have substantial effects on attitudes toward immigration and preferences with regard to immigration policy among this large and diverse set of voters

immigrants labour market performance and social insurance using longitudinal data from the date of arrival we study long term labour market and social insurance outcomes for all major immigrant cohorts to norway since 1970 immigrants from high income countries performed as natives while labour migrants from low income source countries had declining employment rates and increasing disability programme participation over the lifecycle refugees and family migrants assimilated during the initial period upon arrival but labour market convergence halted after a decade and was accompanied by rising social insurance rates for the children of labour migrants of the 1970s we uncover evidence of intergenerational assimilation in education earnings and fertility

on the ir relevance of distribution and labor supply distortion to government policy should the assessment of government policies such as the provision of public goods and the control of externalities deviate from first best principles to account for distributive effects and the distortionary cost of labor income taxation for example is the optimal extent of public goods provision smaller than indicated by the samuelson rule because finance is distortionary or should environmental regulations fail to internalize externalities fully if the incidence of the regulations is regressive it is suggested that these questions are best addressed by considering distribution neutral implementation in which budget balance is achieved by choosing an adjustment to the income tax that offsets the distributive impact of the policy in question in basic cases both distribution and labor supply distortion are moot because the target policy and the tax adjustment produce offsetting effects on each thus traditional first best principles provide good benchmarks for policy analysis after all moreover even when actual implementation will not be distribution neutral in aggregate distribution neutral policy analysis has many conceptual and practical virtues that render it quite useful to investigators

migration and optimal income taxes abstract the issue addressed in this paper is the optimal taxation of incomes earned in the home economy and of incomes earned abroad when people can migrate as a preliminary the optimal taxation of home incomes when there is migration and no taxation of foreign incomes is discussed then in a more general setting we deal with optimal taxation of different kinds of labour when another kind of labour is not taxable and show how this bears on the taxation of foreign incomes the last sections of the paper analyse a simple model in which people choose between taxable labour at home taxable labour abroad and untaxable labour a condition is found implying that the optimal tax on foreign income is higher than on the home income of a person of equal utility

us food aid and civil conflict we study the effect of us food aid on conflict in recipient countries our analysis exploits time variation in food aid shipments due to changes in us wheat production and cross sectional variation in a country s tendency to receive any us food aid according to our estimates an increase in us food aid increases the incidence and duration of civil conflicts but has no robust effect on interstate conflicts or the onset of civil conflicts we also provide suggestive evidence that the effects are most pronounced in countries with a recent history of civil conflict jel d74 f35 o17 o19 q11 q18 we are unable to determine whether our aid helps or hinders one or more parties to the conflict it is clear that the losses particularly looted assets constitutes a serious barrier to the efficient and effective provision of assistance and can contribute to the war economy this raises a serious challenge for the humanitarian community can humanitarians be accused of fueling or prolonging the conflict in these two countries medecins sans frontieres amsterdam 1

the marginal rate of corruption in public programs evidence from india abstract optimal fiscal policy depends on the marginal benefits of public spending in developing countries corrupt officials often embezzle funds so optimal policy should reflect marginal corruption we analyze marginal corruption in the context of a statutory wage increase in india s employment guarantee scheme strikingly workers received none of the increase even though initially they were on average overpaid the data are inconsistent with theories of voice in which the threat of complaints limits corruption but consistent with theories of exit in which outside options in the private sector limit how much rent officials can extract

economic versus cultural differences forms of ethnic diversity and public goods provision groups between group inequality bgi we show that elf cultural fractionalization cf and bgi measure different things and that the choice between them has an important impact on our understanding of which countries are most ethnically diverse furthermore empirical tests reveal that bgi has a large robust and negative relationship with public goods provision whereas cf elf and overall inequality do not diversity is widely held to make governance more difficult such diversity is associated with low production of public goods poor economic growth and high levels of corruption violence and civil conflict but diversity hardly sentences a country to poor political and economic outcomes latvia for example has better governance indicators than brazil and zambia has better governance indicators than nigeria even though these pairs of countries have similar levels of ethnolinguistic fractionalization elf why then do some countries cope more successfully with ethnic diversity than others this article addresses this question by focusing on the

monopsony power in migrant labor markets evidence from the united arab emirates by exploiting a reform in the united arab emirates that relaxed restrictions on employer transitions we provide new estimates of the monopsony power of firms over migrant workers our results show that the reform increased incumbent migrants earnings and firm retention this occurs despite an increase in employer transitions and is driven by a fall in country exits while the outcomes of incumbents improved the reform decreased demand for new migrants and lowered their earnings these results are consistent with a model of monopsony in which firms face upward sloping labor supply curves for both new recruits in source countries and incumbent migrants

inequality among world citizens 1820 1992 this paper investigates the distribution of well being among world citizens during the last two centuries the estimates show that inequality of world distribution of income worsened from the beginning of the 19th century to world war ii and after that seems to have stabilized or to have grown more slowly in the early 19th century most inequality was due to differences within countries later it was due to differences between countries inequality in longevity also increased during the 19th century but then was reversed in the second half of the 20th century perhaps mitigating the failure of income inequality to improve in the last decades jel d31 f0 n0 o0
