occupational choice and the process of development this paper models economic development as a process of institutional transformation by focusing on the interplay between agents occupational decisions and the distribution of wealth because of capital market imperfections poor agents choose working for a wage over self employment and wealthy agents become entrepreneurs who monitor workers only with sufficient inequality however will there be employment contracts otherwise there is either subsistence or self employment thus in static equilibrium the occupational structure depends on distribution since the latter is itself endogenous we demonstrate the robustness of this result by extending the model dynamically and studying examples in which initial wealth distributions have long run effects in one case the economy develops either widespread cottage industry self employment or factory production employment contracts depending on the initial distribution in the other example it develops into prosperity or stagnation

sale of visas a smuggler s final song is there a way of eliminating human smuggling we set up a model to simultaneously determine the provision of human smuggling services and the demand from would be migrants a visa selling policy may be successful at eliminating human smugglers by eroding their profits but it necessarily increases immigration in contrast re enforced repression decreases migration but uses the help of cartelized smugglers to overcome this trade off we study how legalisation and repression can be combined to eliminate human smuggling while controlling migration flows this policy mix also has the advantage that the funds raised by visa sales can be used to finance additional investments in border and internal controls employer sanctions and deportations simulations of the policy implications highlight the complementarities between repression and legalisation and call into question the current policies

the carnegie conjecture some empirical evidence this paper examines tax return generated data on the labor force behavior of people before and after they receive inheritances the results are consistent with andrew carnegie s century old assertion that large inheritances decrease a person s labor force participation for example a single person who receives an inheritance of about 150 000 is roughly four times more likely to leave the labor force than a person with an inheritance below 25 000 additional albeit weaker evidence suggests that large inheritances depress labor supply even when participation is unaltered warren kendall heir to an insurance company fortune says he s worth about 5 million and has an income of about oh 300 and some thousand a year h e has never held a job or wanted to going down to sea in cruise ships is his full time pursuit he estimates that he has taken about 250 cruises over the past couple of decades spending at least 50 percent to 70 percent of the year afloat morgenthaler 1991 p al

the dual nature of public goods and congestion the role of fiscal policy revisited the role of fiscal policy is examined when public goods provide both productive and utility services in the presence of congestion the consumption tax is shown to be distortionary optimal fiscal policy involves using consumption based instruments in conjunction with the income tax an income tax financed increase in government spending dominates both lump sum and consumption tax financing replacing the lump sum tax with an income tax to finance a given level of spending dominates introducing an equivalent consumption tax these results contrast sharply with the literature where the consumption tax is generally viewed as the least distortionary source of public finance on re examine le role de la politique fiscale quand les biens publics fournissent a la fois des services productifs et de bien etre quand il y a congestion on montre que la taxe sur la consommation cree des distorsions la politique fiscale optimale consiste a faire bon usage des taxes sur la consommation en conjonction avec l impot sur le revenu une depense gouvernementale financee par l impot sur le revenu est preferable a un financement par un paiement forfaitaire ou une taxe sur la consommation remplacer le paiement forfaitaire par un impot sur le revenu pour financer un niveau donne de depense vaut mieux qu introduire une taxe equivalente sur la consommation ces resultats contrastent vivement avec ce qu on trouve dans la litterature specialisee ou l on considere generalement la taxe sur la consommation comme la source de finance publique qui cree le moins de distorsion

migration policy african population growth and global inequality according to recent un projections more than 50 per cent of the growth in world population over the next half century will be due to population growth in africa given this any policy that influences african demography will have a significant impact on the world distribution of income in this study we discuss the potential for migration policies to affect fertility and education decisions and hence population growth in africa we present the results from different scenarios for more or less restrictive selective migration policies and derive their implications for the evolution of world inequality

migration and development research is moving far beyond remittances research on migration and development has recently changed in two ways first it has grown sharply in volume emerging as a proper subfield second while it once embraced principally rural urban migration and international remittances migration and development research has broadened to consider a range of international development processes these include human capital investment global diaspora networks circular or temporary migration and the transfer of technology and cultural norms for this special issue we present a selection of frontier migration and development research that instantiates these trends

the political economy of naturalization this paper presents a political economy model in which self interested natives decide when citizenship and or voting rights should be granted to foreign born workers native voters know that immigrants hold different political preferences and would thus tend to postpone their enfranchisement as much as possible they also consider however that a more restrictive naturalization policy may reduce the gains from immigration we find that the optimal timing of naturalization depends on the quantity quality productivity and preferences of potential immigrants the political composition and the age structure of the native population as well as the sensitivity of migration choices to the citizenship issue

income distribution and macroeconomics this paper analyzes the role of wealth distribution in macroeconomics through investment in human capital it is shown that in the presence of credit markets imperfections and indivisibilities in investment in human capital the initial distribution of wealth affects aggregate output and investment both in the short and in the long run as there are multiple steady states this paper therefore provides an additional explanation for the persistent differences in per capita output across countries furthermore the paper shows that cross country differences in macroeconomic adjustment to aggregate shocks can be attributed among other factors to differences in wealth and income distribution across countries

brain drain and economic growth theory and evidence we focus on the impact of migration prospects on human capital formation and growth in a small open developing economy we assume that agents are heterogeneous in skills and take their educational decisions in a context of uncertainty regarding future migrations we distinguish two growth effects an ex ante brain effect migration prospects foster investments in education because of higher returns abroad and an ex post drain effect because of actual migration flows the case for a beneficial brain drain bbd emerges when the first effect dominates i e when the average level of human capital is higher in the economy opened to migrations than in the closed economy we derive the theoretical conditions required for such a possibility to be observed using cross section data for 37 developing countries we find that the possibility of a bbd could be more than a theoretical curiosity

infrastructure and inequality abstract we develop a model in which public capital is both an engine of growth and a determinant of the distributions of wealth income and welfare government investment increases wealth inequality over time regardless of its financing the time path of income inequality is however highly sensitive to financing policies and is often characterized by sharp intertemporal tradeoffs with income inequality declining in the short run but increasing in the long run public investment generates a positive correlation between growth and income inequality along the transition path but their short run and long run relationship depends critically on i how externalities impinge on allocation decisions ii financing policies and iii the time period of consideration finally these policies also generate sharp trade offs between average welfare and its distribution with government investment improving average welfare but also increasing its dispersion our results are obtained numerically but extensive sensitivity analysis confirms their robustness across key parameter values

immigrant selection in the oecd in this paper we examine the determinants of educational selectivity in immigration using immigrant stock data for 70 source countries and 21 oecd destination countries as observed in the year 2000 2001 we develop a variant of the roy model to estimate the determinants of educational selectivity two key findings emerge first the effect of the skill premium which is at the core of the roy model can be observed only after we take into account the poverty constraints operating in the source countries second cultural similarities colonial legacies and physical distance are often more important determinants of educational selectivity than wage incentives or selective immigration policy

do place based tax incentives create jobs abstract in this paper we evaluate the effectiveness of place based payroll taxes in stimulating local employment by exploiting a unique policy setting in norway where a system of geographically differentiated payroll taxes was suddenly abolished due to an eu regulation the reform was enforced independently of the regional labor market developments creating arguably exogenous variation in the payroll tax rates that firms in different local labor markets faced over time we find evidence of partial shifting of payroll tax increases on to worker wages as well as a significant decline in local employment these findings suggest that in settings with some degrees of wage rigidity place based payroll tax incentives can be effective in stimulating local employment

the economic consequences of brain drain of the best and brightest microeconomic evidence from five countries this article presents results of innovative surveys that tracked academic high achievers from five countries to wherever they moved in the world to directly measure at the micro level the channels through which high skilled emigration affects sending countries there are high levels of emigration and of return and the income gains to the best and brightest from migrating are an order of magnitude greater than any other effect most high skilled migrants from poorer countries remit but involvement in trade and foreign direct investment is rare fiscal costs vary widely but are much less than the benefits to the migrants themselves two narratives drive discussions of the development impact of high skilled migration the first is the idea of a brain drain whereby the departure of doctors teachers engineers scientists and other highly skilled workers decimates the human capital and fiscal revenues of sending countries bhagwati and hamada 1974 such fears lead to calls for policies to restrict the flow of highly skilled workers such as demands that developed countries stop recruiting doctors from developing nations and efforts by developing nations to restrict the ease of their highly skilled individuals migrating 1 contrasting with this is the view of a highly educated diaspora as a potent force for developing the local economy through remittances trade foreign direct investment fdi and knowledge transfers with the experience of india and china in setting up technology firms as a result of diaspora working in silicon valley a prominent example saxenian 2002 economists have also emphasised that the possibility of migrating may spur human capital accumulation potentially leading to a net increase in the education levels of those in the home country 2

migration remittances and the brain drain a symposium in memory of riccardo faini an introduction it seems inevitable that international migration will be one of the major challenges of the twenty first century lower transaction and communication costs have already greatly eased the formation of migrant networks and reduced migration costs for long a deterrent to migration from developing countries to developed countries demographics also keep migratory policies near the top of policy agendas in developed countries where dependency ratios continue to rise migratory pressures will also increase as falling dependency ratios in developing countries contribute to the swelling of their labor forces designing immigration policies in industrial countries will be a challenge especially in the european union where negative attitudes toward immigrants from poor non european union eu countries persist

what do we know about global income inequality in this paper we review the recent literature on global interpersonal income inequality while all estimates agree that the level is very high with a gini of between 0 630 and 0 686 in the 1990s there is no consensus regarding the direction of change we discuss methodological issues including the use of national accounts versus survey based estimates of mean income or consumption and the choice of purchasing power parity exchange rates findings of a rise or fall in global income inequality are not robust across different estimation methods and datasets given the diversity of estimates and various sources of uncertainty including gaps and errors in the underlying data we conclude there is insufficient evidence to determine the direction of change in global interpersonal inequality in recent decades

globalization brain drain and development this paper reviews four decades of economics research on the brain drain with a focus on recent contributions and on development issues we first assess the magnitude intensity and determinants of the brain drain showing that brain drain or high skill migration is becoming a dominant pattern of international migration and a major aspect of globalization we then use a stylized growth model to analyze the various channels through which a brain drain affects the sending countries and review the evidence on these channels the recent empirical literature shows that high skill emigration need not deplete a country s human capital stock and can generate positive network externalities three case studies are also considered the african medical brain drain the exodus of european scientists to the united states and the role of the indian diaspora in the development of india s information technology sector we conclude with a discussion of the implications of the analysis for education immigration and international taxation policies in a global context

distributional dynamics in a neoclassical growth model the role of elastic labor supply we examine the evolution of the distributions of wealth and income in a ramsey model in which agents differ in their initial capital endowment and where the labor supply is endogenous the assumption that the utility function is homogeneous implies that the macroeconomic equilibrium is independent of the distribution of wealth and allows us to characterize fully income and wealth dynamics we find that although the dynamics of the distribution of wealth are similar under fixed and flexible labor those of the income distribution are not in response to a structural change income inequality may move in opposite ways depending on whether or not the labor supply is fixed

global talent flows the global distribution of talent is highly skewed and the resources available to countries to develop and utilize their best and brightest vary substantially the migration of skilled workers across countries tilts the deck even further using newly available data the paper first reviews the landscape of global talent mobility which is both asymmetric and rising in importance next the determinants of global talent flows at the individual and firm levels are presented and some important implications are sketched third the national gatekeepers for skilled migration and broad differences in approaches used to select migrants for admission are reviewed looking forward the capacity of people firms and countries to successfully navigate this tangled web of global talent will be critical to their success

top incomes in the long run of history a recent literature has constructed top income shares time series over the long run for more than twenty countries using income tax statistics top incomes represent a small share of the population but a very significant share of total income and total taxes paid hence aggregate economic growth per capita and gini inequality indexes are sensitive to excluding or including top incomes we discuss the estimation methods and issues that arise when constructing top income share series including income definition and comparability over time and across countries tax avoidance and tax evasion we provide a summary of the key empirical findings most countries experience a dramatic drop in top income shares in the first part of the twentieth century in general due to shocks to top capital incomes during the wars and depression shocks top income shares do not recover in the immediate postwar decades however over the last thirty years top income shares have increased substantially in english speaking countries and in india and china but not in continental european countries or japan this increase is due in part to an unprecedented surge in top wage incomes as a result wage income comprises a larger fraction of top incomes than in the past finally we discuss the theoretical and empirical models that have been proposed to account for the facts and the main questions that remain open

income maximization and the selection and sorting of international migrants abstract two prominent features of international labor movements are that the more educated are more likely to emigrate positive selection and more educated migrants are more likely to settle in destination countries with high rewards to skill positive sorting using data on emigrant stocks by schooling level and source country in oecd destinations we find that a simple model of income maximization can account for both phenomena results on selection show that migrants for a source destination pair are more educated relative to non migrants the larger is the absolute skill related difference in earnings between the destination country and the source results on sorting indicate that the relative stock of more educated migrants in a destination is increasing in the absolute earnings difference between high and low skilled workers we use our framework to compare alternative specifications of international migration estimate the magnitude of migration costs by source destination pair and assess the contribution of wage differences to how migrants sort themselves across destination countries

migration of skilled workers policy interaction between host and source countries abstract we examine the interaction between policies of the host and source countries in the context of a model of skilled worker migration the host country aims to provide low cost labor for its employers while also taking into consideration the fiscal burden of providing social services to immigrants it optimizes by setting a time limit on the duration of a guest worker s permit the source country maximizes its net output by optimally choosing the amount of training provided to its citizens some of whom may migrate we solve for the nash and cooperative equilibrium values of the policy instruments

the global economic crisis and the effect of immigrant workers on native born employment in europe the debate regarding the economic effects of employing immigrants has attracted renewed interest in european countries since the economic crisis we provide an approximation of the labour market effects of immigrant workers in four european countries during the global economic crisis after briefly analysing native and foreign born worker conditions for the most recent period our analysis focuses on the correlation between the stock of immigrant workers and the number of native labour market workers across several segments of the labour market using a simple model approach using eurostat and lfs labour force survey data we estimate a structural dynamic model using the generalised method of moments gmm to examine adjustment dynamics in the labour market and labour market segment and worker educational levels countries of origin and genders overall the empirical results suggest that immigrant labour force effects on native born worker employment rates have been persistent and but weak throughout the business cycle these effects are globally positive and immigrant origins do not appear to change the nature of their impact we offer some explanations for these findings related to dual labour markets and to differences in levels of substitution among native and immigrant workers

five questions on international migration and development the movement of people in search of better economic conditions and a more secure environment is as old as human history such movements not only profoundly affect the lives of the migrants but also lead to significant economic and social transformations in migrants countries of origin and destination in recent years a significant increase in the growth of international migration and remittance flows and in awareness of their development impact has led to a resurgence of interest by academics policymakers and analysts in what has been referred to as the third leg of globalization the other two being international trade and international capital flows this symposium issue gathers some of the papers presented at the second international migration and development conference held at the world bank on september 10 11 2009 the five articles in this symposium issue fall into two groups

eight questions about brain drain high skilled emigration is an emotive issue that in popular discourse is often referred to as brain drain conjuring images of extremely negative impacts on developing countries recent discussions of brain gain diaspora effects and other advantages of migration have been used to argue against this but much of the discussion has been absent of evidence this paper builds upon a new wave of empirical research to answer eight key questions underlying much of the brain drain debate 1 what is brain drain 2 why should economists care about it 3 is brain drain increasing 4 is there a positive relationship between skilled and unskilled migration 5 what makes brain drain more likely 6 does brain gain exist 7 do high skilled workers remit invest and share knowledge back home and 8 what do we know about the fiscal and production externalities of brain drain

emigration and democracy migration is an important yet neglected determinant of institutions this paper documents the channels through which emigration affects home country institutions and considers dynamic panel regressions for a large sample of developing countries the authors find that emigration and human capital both increase democracy and economic freedom this implies that unskilled skilled emigration has a positive ambiguous impact on institutional quality simulations show an impact of skilled emigration that is generally positive significant for a few countries and for many countries once incentive effects of emigration on human capital formation are accounted for

the brain drain and the world distribution of income abstract skilled emigration or brain drain from developing to developed countries is becoming the dominant pattern of international migration today such migration is likely to affect the world distribution of income both directly through the mobility of people and indirectly as the prospect of migration affects the rate of return to education in both the sending and receiving economies this migration pattern will therefore affect human capital accumulation and fertility decisions in both the sending and receiving economies this paper analyzes these effects in a dynamic two country model of the world economy where agents in both countries make optimal fertility and human capital decisions the implications of the analysis for the world distribution of income are derived in the light of recent empirical findings of the brain drain literature the analysis shows that the current trend towards predominantly skilled emigration from poor to rich countries may in the long run increase inequality in the world distribution of income as relatively poor countries grow large in terms of population in the short run however it is possible for world inequality to fall due to rises in gdp per capita in large developing economies with sufficiently low skilled emigration rates

appropriate technology and income differences this article studies the relative productivity of skilled to unskilled workers across countries relative productivities are broken down into the human capital embodied in skilled workers and relative physical productivities reflecting production techniques i find that skilled workers from poorer countries embody less human capital and are also relatively less physically productive furthermore results show that production techniques are inappropriate for most low income countries and these countries experience large increases in gdp per capita by increasing the relative physical productivity of skilled to unskilled workers this suggests that there are significant barriers to the adoption of skill complementary technologies

measuring international skilled migration a new database controlling for age of entry recent data on international migration of skilled workers define skilled migrants by education level without distinguishing whether they acquired their education in the home or the host country this article uses immigrants age of entry as a proxy for where they acquired their education data on age of entry are available from a subset of receiving countries that together represent 77 percent of total skilled immigration to countries of the oecd organization for economic co operation and development using these data and a simple gravity model to estimate the age of entry structure of the remaining 23 percent alternative brain drain measures are proposed that exclude immigrants who arrived before ages 12 18 and 22

taxation and income distribution dynamics in a neoclassical growth model we examine how changes in tax policies affect the dynamics of the distributions of wealth and income in a ramsey model in which agents differ in their initial capital endowment the endogeneity of the labor supply plays a crucial role in determining inequality as tax changes that affect hours of work will affect the distribution of wealth and income reinforcing or offsetting the direct redistributive impact of taxes our results indicate that tax policies that reduce the labor supply are associated with lower output but also with a more equal distribution of after tax income we illustrate these effects by examining the impact of recent tax changes observed in the us and in european economies

is migration a good substitute for education subsidies assuming a given educational policy the recent brain drain literature reveals that skilled migration can boost the average level of schooling in developing countries this paper introduces educational subsidies determined by governments concerned by the number of skilled workers remaining in the country the theoretical analysis shows that developing countries can benefit from skilled emigration when educational subsidies entail high fiscal distortions however when taxes are not too distortionary it is desirable to impede emigration and subsidize education the authors investigate the empirical relationship between educational subsidies and migration prospects obtaining a negative relationship for 105 countries based on this result the analysis revisits the country specific effects of skilled migration upon human capital the findings show that the endogeneity of public subsidies reduces the number of winners and increases the magnitude of the losses

dynamic analysis of an endogenous growth model with public capital this paper develops an endogenous growth model with productive public capital along with private capital in a spirit similar to that of r j barro 1990 since the authors model includes two stock variables it has transitional dynamics unlike most of the previous studies on endogenous growth including barro s where concerns are restricted to the steady state analysis first they show that the transitional path is unique and stable second the character of the transitional path is explored third the authors show that the optimal tax rate is smaller than the rate that maximizes the national growth rate with a log linear utility function copyright 1993 by the editors of the scandinavian journal of economics

what have we learned from three decades of research on the productivity of public capital the last three decades have witnessed a great deal of research effort devoted to measuring the private output elasticity of public capital the wide range of available estimates have precluded any consensus so far however this paper reconciles the empirical findings of the literature by quantitatively analyzing a sample of 578 estimates collected from 68 studies for the 1983 2008 period using meta regression analysis we show how study design characteristics and publication bias can explain a large fraction of the variation across estimates we find a short run output elasticity of public capital supplied at the central government level of 0 083 which increases to 0 122 in the long run if in addition only core infrastructure at a regional local level of government is considered these estimates are almost doubled the average output elasticity of public capital amounts to 0 106 our results suggest that public capital is undersupplied in oecd economies
