return migration uncertainty and precautionary savings this paper presents a life cycle model where migrants determine re migration and consumption simultaneously in a stochastic environment whether precautionary savings of migrants are above or below those of natives is ambiguous in general the sign depends on the risk in host and home country labor markets and on the correlation of labor market shocks furthermore the effect of an uncertain environment on migration and re migration plans cannot be unambiguously signed for the general case it depends on the size of the wage differential as well as the relative risk the migrant exhibits in the two labor markets

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

the effect of immigration along the distribution of wages this paper analyses the effect immigration has on wages of native workers unlike most previous work we estimate wage effects along the distribution of wages we derive a flexible empirical strategy that does not rely on pre allocating immigrants to particular skill groups in our empirical analysis we demonstrate that immigrants downgrade considerably upon arrival as for the effects on native wages we find that immigration depresses wages below the 20th percentile of the wage distribution but leads to slight wage increases in the upper part of the wage distribution the overall wage effect of immigration is slightly positive the positive wage effects we find are although modest too large to be explained by an immigration surplus we suggest alternative explanations based on the idea that immigrants are paid less than the value of what they contribute to production generating therefore a surplus and we assess the magnitude of these effects

wealth effects distribution and the theory of organization abstract we construct a general equilibrium model of firm formation in which organization is endogenous firms are coalitions of agents providing effort and investment capital effort is unobservable unless a fixed monitoring cost is paid and borrowing is subject to a costly state verification problem because incentives vary with an agent s wealth different types of agents become attractive firm members under different circumstances when borrowing is not costly firms essentially consist of one type of agent and are organized efficiently but when the costly state verification problem is sufficiently severe firm organization will depend on the distribution of wealth with enough inequality it will tend to be dictated by incentives of rich agents to earn high returns to wealth even if the chosen organizational form is not a technically efficient way to provide incentives journal of economic literatureclassification numbers d2 d31 j41 l2

occupational choice and dynamic incentives we study an overlapping generations version of the principal agent problem where incentive contracts are determined in general equilibrium all individuals are workers when young but have a choice between becoming entrepreneurs or remaining workers when old imperfections in the credit market give rise to rents in entrepreneurial activities involving capital these rents motivate poor young agents to work hard and save to overcome the borrowing constraints with a labour market that is subject to moral hazard the increased effort raises social welfare policies that reduce credit market imperfections or redistribute income may reduce welfare by dampening this effect

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

self selection of emigrants theory and evidence on stochastic dominance in observable and unobservable characteristics the roy model has more precise predictions about the self selection of migrants than previously realised the conditions shown to result in positive or negative selection in terms of expected earnings also imply a stochastic dominance relationship between the earnings distributions of migrants and non migrants we test these predictions using the danish full population administrative data we find strong evidence of positive self selection of emigrants in terms of pre emigration earnings and residual earnings the income distribution for the migrants almost stochastically dominates the distribution for the non migrants decomposing the self selection in total earnings reveals that unobserved abilities play the dominant role

the effect of emigration from poland on polish wages in this paper we analyse the effect of emigration from poland on polish wages focusing on the 1998 2007 period for poland we use a unique dataset that contains information about household members who are currently living abroad which allows us to develop region specific emigration rates and to estimate the effect of emigration on wages using within region variation our findings show that emigration led to a slight increase in wages for high and medium skilled workers which are the two groups with the largest relative outmigration rates workers at the low end of the skill distribution might have experienced wage decreases

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

a model of adjuncts in higher education abstract we examine the phenomenon of the expanded use of non tenure track positions adjuncts and construct a supply side harris todaro model low adjunct wages are attributable to a hope rent from the gap between private opportunities and tenure track utility

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

the impact of immigration on the british labour market using data from the british labour force survey this article provides an empirical investigation of the way immigration affects labour market outcomes of native born workers in britain set beside a theoretical discussion of the underlying economic mechanisms we discuss problems arising in empirical estimation and how to address them we show that the overall skill distribution of immigrants is remarkably similar to that of the native born workforce we find no strong evidence that immigration has overall effects on aggregate employment participation unemployment and wages but some differences according to education

the intergenerational state education and pensions allocation is inefficient when generations overlap this failure can be mitigated by properly designed social arrangements we show that public financing of education and public pensions can be designed to implement an intergenerational transfer scheme supporting the complete market allocation neither the public financing of education nor the pension scheme we consider resemble standard ones in our mechanism via the public education system the young borrow from the middle aged to invest in human capital they pay back the debt via a social security tax the proceedings of which finance pension payments when the complete market allocation is achieved the rate of return implicit in this borrowinglending scheme should equal the market rate of return

cooperation punishment and immigration abstract we study the incentive to cooperate in a society comprised of citizens and immigrants the level of cooperation is governed by a steady state under population dynamics along with the behavior of individual citizens and immigrants we provide an equilibrium characterization exhibiting a uniquely determined positive level of cooperation in society we then use this framework to study the impact of government programs aimed at punishing immigrants who defect when agents produce offspring we show that a consequence of such punishment is that while the incentive for immigrants to defect decreases there is an equilibrium substitution effect whereby citizens realize an increased incentive to defect

managerial incentive problems a dynamic perspective the paper studies how a person s concern for a future career may influence his or her incentives to put in effort or make decisions on the job in the model the person s productive abilities are revealed over time through observations of performance there are no explicit output contingent contracts but since the wage in each period is based on expected output and expected output depends on assessed ability an implicit contract links today s performance to future wages an incentive problem arises from the person s ability and desire to influence the learning process and therefore the wage process by taking unobserved actions that affect today s performance the fundamental incongruity in preferences is between the individual s concern for human capital returns and the firm s concern for financial returns the two need be only weakly related it is shown that career motives can be beneficial as well as detrimental depending on how well the two kinds of capital returns are aligned it is well understood by now that informational externalities may place special demands on the organization of economic exchange simple price mediated markets will frequently fail in the presence of asymmetric information in that case more elaborate contractual arrangements have to be used as substitutes for the price system lately considerable effort has been devoted to the analysis of contracting under incomplete information with the objective to understand the range of economic institutions that emerge in response to the failure of the price system the analysis of moral hazard has played a prominent role in this development moral hazard problems arise when for some reason or another transacting parties cannot contract contingent on the delivery of the good for instance in buying labour services it may be that the amount of labour supplied is not directly observable precluding a simple exchange of wage for labour as a partial remedy to this problem an imperfect mutually observed signal about the supply of labour can be used as a proxy in the contract frequently output is taken as such a proxy the drawback is that output is often influenced by other factors than labour input which induce undesirable risk into the contract one is therefore faced with a tradeoff between allocating risk associated with incomplete observability and providing incentives for a proper supply of labour gaining insight into this tradeoff is important not only for understanding contracting in the small e g managerial incentive schemes but also because it is closely related to the fundamental tension between equity and efficiency in the society as a whole while our understanding of moral hazard has advanced a lot in past years it is clear that much work remains an important question that has received little attention until

an introduction to the economics of immigration in oecd countries the share of the foreign born in oecd countries is increasing and this article summarizes economics research on the effects of immigration in those nations four broad topics are addressed labor market issues fiscal questions the political economy of immigration and productivity international trade extreme concerns about deleterious labour market and fiscal impacts following from new immigrants are not found to be warranted however it is also clear that government policies and practices regarding the selection and integration of new migrants affect labour market fiscal and social cultural outcomes policies that are well informed well crafted and well executed beneficially improve population welfare

optimal incentive contracts in the presence of career concerns theory and evidence this paper studies optimal incentive contracts when workers have career concerns concerns about the effects of current performance on future compensation we show that the optimal compensation contract optimizes total incentives the combination of the implicit incentives from career concerns and the explicit incentives from the compensation contract thus the explicit incentives from the optimal compensation contract should be strongest for workers close to retirement because career concerns are weakest for these workers we find empirical support for this prediction in the relation between chief executive compensation and stock market performance

the impact of immigration on the structure of wages theory and evidence from britain immigration to the uk particularly among more educated workers has risen appreciably over the past 30 years and as such has raised labor supply however studies of the impact of immigration have failed to find any significant effect on the wages of native born workers in the uk this is potentially puzzling since there is evidence that changes in the supply of educated natives have had significant effects on their wages using a pooled time series of british cross sectional micro data on male wages and employment from the mid 1970s to the mid 2000s this paper offers one possible resolution to this puzzle namely that in the uk natives and foreign born workers are imperfect substitutes we show that immigration has primarily reduced the wages of immigrants and in particular of university educated immigrants with little discernable effect on the wages of the native born

wage and effort dispersion we construct a simple model where ex ante homogeneous firms offer jobs with different wages and effort levels to ex ante homogeneous workers a minimum wage is shown to be welfare reducing because of its effect on the distribution of wages and effort

excessive public employment and rent seeking traps we propose a model where the size of the public sector and aggregate output are interrelated through the occupational choice of agents who differ in their skill level and degree of public mindedness when the public sector attracts bureaucrats with low degree of public service motivation they will use their position to rent seek by employing an excessive number of unskilled workers this leads to an equilibrium with relatively high unskilled wages which lowers profits and deters entrepreneurship conversely an equilibrium with a lean public sector and greater private economic activity arises when public service motivated agents populate the state bureaucracy these agents exert high effort and employ a limited number of unskilled workers our model also shows that a bloated public sector with high wages may be supported by the unskilled agents

financial constraints and occupational choice in thai villages abstract financial constraints and entrepreneurship are key factors affecting economic performance in developing countries i formulate and solve a model of occupational choice with moral hazard under three alternative financial market environments savings only borrowing and lending with default and moral hazard constrained insurance i use computationally efficient techniques based on mechanism design genetic algorithms and maximum likelihood to estimate and statistically test these models of financial constraints using occupational choice data from thai villages i find evidence that the saving only regime is rejected in favor of regimes allowing for borrowing and or insurance especially in higher wealth data stratifications a direct test between the borrowing and insurance regimes reveals that neither can be rejected in favor of the other allowing ex ante lotteries over wealth improves the explanatory power of the model i also find evidence for differences in the best fitting regimes by region wealth and access to formal credit

job duration seniority and earnings an important stylized fact about labor markets is that workers with longer seniority with their current employer have higher earnings than other workers with the same total labor market experience this study shows that workers in longer jobs earn more throughout than workers in a series of shorter jobs and that the measured positive cross sectional return seniority is largely a statistical artifact due to the correlation of seniority with an omitted variable representing the quality of the worker the job or the worker employer match the implication is tha t earnings do not in fact rise very much with seniority copyright 1987 by american economic association

endogenous capital market imperfections human capital and intergenerational mobility in this paper capital market imperfections are endogenized considering an adverse selection problem between banks and borrowers we develop a growth model with linear olg wealth dynamics where agents are heterogeneous in terms of observable wealth and ability which is private information we show that banks react to this informational asymmetry by granting higher loans to talented borrowers this in turn helps poor and talented agents to become educated and catch up with the rich agents furthermore the credit market friction leads to greater human capital accumulation

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

behavior of the firm under regulatory constraint a recent article by akira takayama discusses an earlier paper by harvey averch and leland l johnson on fair rate of return regulation of public utilities although takayama p 255 agrees with averch and johnson s general conclusions that a firm will tend to increase its investment with the introduction of an active constraint on its rate of return he criticizes the a j argument as being confusing ambiguous and in error takayama then attempts a clarification and presents a new formulation which leads to the a j result quoted above this comment will discuss several of takayama s criticisms in addition to showing that the so called a j effect cannot be derived from the basic assumptions made by both averch and johnson and takayama 1 we will show that the very assumptions used to prove the a j effect by defining the region of x require an assumption that the a j effect exists in the first place

poverty traps and nonlinear income dynamics with measurement error and individual heterogeneity theories of poverty traps stand in sharp contrast to the view that anybody can make it through hard work and thrift however empirical detection of poverty traps is complicated by the lack of long panels measurement error and attrition this paper shows how dynamic pseudo panel methods can overcome these difficulties allowing estimation of non linear income dynamics and testing for the presence of poverty traps the paper explicitly allows for individual heterogeneity in income dynamics to account for the possibility that particular groups of individuals may face traps even if the average individual does not these methods are used to examine the evidence for a poverty trap in labor earnings income and expenditure in mexico and are compared to panel data estimates from a short rotating panel the results do find evidence of nonlinearities in household income dynamics and demonstrate large bias in the panel data estimates nevertheless even after allowing for heterogeneity and accounting for measurement error the paper finds no evidence of the existence of a poverty trap for any group in the sample

ethnicity and educational achievement in compulsory schooling this article documents that at the start of school pupils from most ethnic groups substantially lag behind white british pupils however these gaps decline for all groups throughout compulsory schooling language is the single most important factor why ethnic minority pupils improve relative to white british pupils poverty in contrast does not contribute to the catch up our results also suggest the possibility that the greater than average progress of ethnic minority pupils in schools with more poor pupils may partly be related to teacher incentives to concentrate attention on particular pupils generated by the publication of school league tables

volatile capital flows and financial integration the role of moral hazard abstract we study a model in which income and capital flows between countries are jointly determined in a world economy with integrated financial markets in a setting that combines risky entrepreneurial activity with moral hazard we find that a shift from autarky to financial integration leads to boom bust cycles in capital flows output and consumption moral hazard causes cycles because financial intermediaries incentivize effort by insisting entrepreneurs take an equity share in their own projects the size of this stake rises with wealth discouraging entrepreneurship and inhibiting capital formation the reverse is true when wealth falls generating cycles

the fiscal impact of immigration on the advanced economies this paper is concerned with the advanced economies it begins with a discussion of the demo graphic issues that have played such a large role in the debate on immigration this is followed by a section on the main problems involved in estimating the fiscal impact of immigration and then a summary of the international evidence on this topic mostly from europe and america separate sections on the uk and on low fertility countries follow the main conclusions are as follows highly skilled migrants normally make a large fiscal contribution whereas unskilled migrants are likely to impose a net cost on native taxpayers if they settle in the receiving country however even unskilled migrants may be net contributors if they eventually depart and make few claims on government expenditure while in the country most empirical studies find that the fiscal contribution of the immigrant population as a whole is quite small the positive contribution of some migrants is largely or wholly offset by the negative contribution of others this finding holds across a variety of countries and methodologies estimates of the net fiscal contribution of immigration normally lie within the range 1 per cent of gdp there are a few exceptions but these refer to countries experiencing demographic collapse and they are based on unrealistic assumptions about the inter generational allocation of future taxes and government expenditure with more realistic assumptions the overall fiscal benefit of immigration is quite small even in these countries these findings suggest that in general there is no strong fiscal case for or against sustained large scale immigration the desirability or otherwise of large scale immigration should be decided on other grounds

precautionary savings by natives and immigrants in germany this paper analyses the savings behaviour of natives and immigrants in germany it is argued that uncertainty about future income and legal status in case of immigrants is a key component in the determination of the level of precautionary savings using the german socio economic panel data it is shown that although immigrants have lower levels of savings and are less likely to have regular savings than natives the gap is significantly narrowed once we take loan repayments and remittances into account moreover we find that marginal propensity to save for immigrants is about 40 higher than that for natives we then exploit a natural experiment arising from a change in nationality law in germany in 2000 to estimate the importance of precautionary savings using a difference in differences approach we find that the easing of the requirements for naturalization has caused significant reductions of savings and remittances for immigrants as a whole in the magnitude of 13 and 29 respectively comparing to the pre reform period our parametric specification shows that the introduction of the new nationality law reduces the gap between natives and immigrants in marginal propensity to save by 40 to 65 depending on the measure of savings used these findings suggest that much of the differences in terms of the savings behaviour between natives and immigrants are driven by the precautionary savings arising from the uncertainties about future income and legal status rather than cultural differences

do poverty traps exist assessing the evidence why did per capita incomes not increase in burundi haiti and nicaragua countries one possible explanation is a poverty trap which can be understood as a set of self reinforcing mechanisms whereby countries start poor and remain poor poverty begets poverty so that current poverty is itself a direct cause of poverty in the future it implies that much poverty is needless in the sense that a different equilibrium is possible and also that one time policy efforts that break the poverty trap may have lasting effects the concept of a poverty trap at the level of national economies is related to and sometimes based on microeconomic foundations that argue for the existence of poverty traps at the household level the authors discuss behavioral poverty traps as a recent area of research for which the evidence is just starting to accumulate and geographic poverty traps as the most likely form of a trap the policy prescriptions that result are then quite different from the calls for a big push in aid or expansion of microfinance to allow people to overcome credit constraints

using cost observation to regulate firms the paper emphasizes the use of accounting data in regulatory or procurement contracts when the supplier 1 has superior information about the cost of the project and 2 invests in cost reduction the main result states that under risk neutrality the supplier announces an expected cost and is given an incentive contract linear in cost overruns this optimal contract moves toward a fixed price contract as the announced cost decreases an investment choice is then introduced and the use of a rate of return regulation is studied

when do employees leave their job for entrepreneurship existing firms are argued to be an important source of new entrepreneurs yet relatively little is known about the characteristics of firms that breed new entrepreneurs we use a large linked employee employer dataset to trace and characterize the types of firms which generate new entrepreneurs in finland we find that such transitions are rare and that smaller firms spawn new entrepreneurs more frequently than larger firms we also find that firms r d intensity and to a lesser extent their productivity are negatively related to the probability that employees transit into entrepreneurship these results are robust to controlling for a number of employee and employer attributes

the effect of immigrant peers in vocational schools abstract this paper provides new evidence on how the presence of immigrant peers in the classroom affects native student achievement the analysis is based on longitudinal administrative data on two cohorts of vocational training students in italy s largest region vocational training institutions provide the ideal setting for studying these effects because they attract not only disproportionately high shares of immigrants but also the lowest ability native students we adopt a value added model and exploit within school variation both within and across cohorts for identification our results show small negative average effects on maths test scores that are larger for low ability native students strongly non linear and only observable in classes with a high top 20 immigrant concentration these outcomes are driven by classes with a high average linguistic distance between immigrants and natives with no apparent additional role played by ethnic diversity

immigration and public finances in oecd countries abstract this paper shows that the macroeconomic and fiscal consequences of international migration are positive for oecd countries and suggests that international migration produces a demographic dividend by increasing the share of the workforce within the population the estimation of a structural vector autoregressive model on a panel of 19 oecd countries over the period 1980 2015 reveals that a migration shock increases gdp per capita through a positive effect on both the ratio of working age to total population and the employment rate international migration also improves the fiscal balance by reducing the per capita transfers paid by the government and per capita old age public spending to rationalize these findings an original theoretical framework is developed this framework highlights the roles of both the demographic structure and intergenerational public transfers and shows that migration is beneficial to host economies characterized by aging populations and large public sectors

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

forward and backward intergenerational goods why is social security good for the environment this paper studies the ability of nonmarket institutions to invest optimally in forward intergenerational goods figs such as education and the environment when agents are selfish or exhibit paternalistic altruism we show that backward intergenerational goods bigs such as social security play a crucial role in sustaining investment in figs without them investment is inefficiently low but with them optimal investment is possible we also show that making the provision of bigs mandatory crowds out the voluntary provision of figs and that population aging can increase investment in figs

pricing efficiency under rate of return regulation some empirical evidence for the electric utility industry the authors test quasi optimal pricing rules for rate of return regulation for a sample of electric utilities they estimate the regulated cost function and demand equations by class of customer for the sample to yield the cost and demand parameters required to assess the utility rate structures the results indicate that the price structure of electricity by class of customer is not quasi optimal and that welfare improvement might be possible under alternative prices searching for the price structure which satisfies the criteria they find that commercial users rates have been too high relative to residential and to a lesser extent industrial rates they note that commercial uses tend to be less organized and more poorly represented in the rate making process 16 references 8 tables

coexistence of long term and short term contracts we study the length of agreements in a market in which infinitely lived firms contract with agents that live for two periods firms differ in the expected values of their projects as do workers in their abilities to manage projects worker effort is not contractible and worker ability is revealed during the relationship the market dictates the trade off between sorting and incentives short and long term contracts often coexist the best firms always use short term contracts to hire high ability senior workers firms with less profitable projects use short term contracts to save on the cost of hiring junior workers whereas intermediate firms use long term agreements to provide better incentives to their workers we relate our results to the optimal assignment literature that follows becker 1973

pricing behavior of the budget constrained public enterprise abstract by assuming that a budget constrained multiproduct public enterprise chooses prices with the goal of maximizing its budget its revenue or its output specific pricing rules can be derived rather than overstating demand elasticities and then pricing like a monopolist as a budget constrained welfare maximizing firm would do the enterprise pursuing one of these alternative goals is shown to understate marginal cost and then price like a monopolist non optimal price discrimination and even cross subsidization may result the outcome tends to be more perverse when statutory entry barriers protect some markets of the enterprise in its pricing the u s postal service has shown some of the signs of such other than welfare maximizing pricing behavior

the direct incidence of corporate income tax on wages a stylised model is provided to show how the direct effect of corporate income tax on wages can be identified in a bargaining framework using cross company variation in tax liabilities conditional on value added per employee using data on 55 082 companies located in nine european countries over the period 1996 2003 we estimate the long run elasticity of the wage bill with respect to taxation to be 0 093 evaluated at the mean this implies that an exogenous rise of 1 in tax would reduce the wage bill by 49 cents only a weak evidence of a difference for multinational companies is found

wish you were here quasi experimental evidence on the effect of education on self reported attitude toward immigrants abstract we use european social survey and labour force survey data from 2002 to 2012 to estimate the causal effect of years of education on european natives opinion toward immigration by exploiting the exogenous discontinuity generated by reforms in compulsory education in europe in the 1940s through the 1990s our findings show that higher levels of education lead to a more positive reported attitude toward immigrants we also investigate the mechanisms behind the effect of education on reported attitudes by evaluating both economic and non economic channels we find that higher levels of education place individuals in occupations that are less exposed to the negative effects of migration although not in sectors occupations where the share of migrants is necessarily smaller suggesting that migrants and low educated natives may be complementary rather than substitutes in the labour market in addition education alters values and the cognitive assessment of the role of immigration in host societies with a positive effect on reported attitude toward diversity and on the assessment of immigration s role in host countries our findings suggest that education as a policy instrument can increase social cohesion in societies that are subject to large immigration flows

oligarchic land ownership entrepreneurship and economic development abstract this paper develops a theory in which oligarchic ownership of land or other natural resources may impede entrepreneurship in the manufacturing sector and may thereby retard structural change and economic development we show that due to oligopsony power of owners in the agricultural labor market higher ownership concentration depresses entrepreneurial investments by landless credit constrained households whose investment possibilities depend on the income earned in the primary sector we discuss historical evidence from latin america india taiwan and south korea which supports our theory

pricing inefficiency under profit regulation rate of return regulation of a profit seeking firm invites two kinds of distortion 1 inputs may not be chosen efficiently to produce given levels of output and 2 the output levels may not be chosen efficiently most attention has been accorded the first of these the technical input distortion it can even be controlled at least in principle under particular goals and by alternative forms of profit regulation we focus here on the second distortion the matter of inefficient output levels caused by nonoptimal relative prices for multiple outputs our approach is to present second best welfare maximizing prices and then see whether firms will adopt them when seeking goals other than welfare goals such as profit sales cost or output and when subject to various constraints which represent profit regulation over a range of possible goals and forms of profit constraint we find pricing efficiency is difficult to achieve by pursuing a maximum sum of profits per unit of capital or of cost pricing efficiency can be approached but the promise of that remedy is limited inducing reasonably efficient relative prices in a multiproduct regulated firm thus is seen as a difficult task that deserves considerably more attention than it has received

credit market frictions and political failure we study how an excessively favorable regulatory environment for banks could arise even with a perfectly competitive credit market in a median voter world in our occupational choice model with heterogeneous wealth endowments market failure due to unobservability of entrepreneurial talent endogenously creates a misalignment between surplus maximizing reforms and reforms that are preferred by the median voter who is a worker this is in contrast to the world without market failure where the electorate unanimously vote in favor of surplus maximizing institutional reforms this paper illustrates how market failure could lead to political failure even in the benchmark political system that is free from capture by interest groups

entrepreneurial talent occupational choice and trickle up policies we study market inefficiencies and policy remedies when agents choose their occupations and entrepreneurial talent is subject to private information untalented entrepreneurs depress the returns to entrepreneurship because of adverse selection the severity of this problem depends on the outside option of entrepreneurs which is working for wages this links credit product and labor markets a rise in wages reduces the adverse selection problem these multimarket interactions amplify productivity shocks and may generate multiple equilibria if it is impossible to screen entrepreneurs then all agents unanimously support a tax on entrepreneurs that drives out the less talented ones however if screening is possible e g if wealthy entrepreneurs can provide collateral for their loans then wealthy entrepreneurs do not support surplus enhancing taxes

workers as creditors performance bonds and efficiency wages from the standpoint of economic theory the difficulty in regulating workers performance distinguishes labor markets from commodity markets commodities do not respond to incentives workers in contrast can quit steal be hung over refuse to cooperate with other workers or generally work at low effort levels since direct monitoring is often costly and unreliable it may not be the profit maximizing solution to this problem economists have discussed various schemes to make productive behavior incentive compatible for workers the most frequently discussed schemes fall into two broad categories efficiency wages and deferred compensation or bonding schemes these schemes have been suggested as explanations for a wide variety of labormarket features that appear anomalous from the conventional supply and demand perspective efficiency wage models can generate equilibria in which there is involuntary unemployment and in which identical workers are paid different wages in jobs that are otherwise equally attractive george a akerlof and janet l yellen 1985 have argued that they can provide an important component of a model of business cycles deferred compensation schemes have been proposed as explanations for upward sloping age earnings profiles mandatory retirement pensions and hierarchical tournament promotion structures 2 because bonding is costless to firms efficiency wage and bonding strategies are often viewed as mutually incompatible profit maximizing firms should offer efficiency wages only in situations where bonding is impossible one widely held view argues that in labor markets where agency issues arise these problems are effectively solved by various bonding arrangements and moreover that this observation helps to explain otherwise peculiar features of some labor markets as mentioned above it follows that efficiency wages do not generally exist proponents of efficiency wage theory argue that there is considerable evidence of widespread agency problems e g large expenditures by many firms on monitoring and that there are barriers to the use of bonds notably moral hazard on the part of firms or legal constraints efficiency wages cannot therefore be ruled out a priori as an equilibrium solution to these agency problems 3 in this paper we study these issues surrounding efficient worker compensation in a framework that allows heterogeneity among firms and integrates the financial and

the dynamics of the wealth distribution and the interest rate with credit rationing are uniquely determined and wealth dispersion among individuals or firms is irrelevant introducing credit rationing into the solow model modifies these conclusions multiple stationary interest rates and wealth distributions can exist because higher initial rates can be self reinforcing through higher credit rationing and lower capital accumulation the wealth accumulation process is ergodic in every steady state but wealth mobility is lower with higher steady state interest rates aggregate output is higher in steady states with lower interest rates because credit is better allocated short run interest rate or distribution shocks can be self sustaining and can have long run effects on output through the induced dynamics of the wealth distribution and credit rationing

empowerment and efficiency tenancy reform in west bengal the paper analyzes the effect of agricultural tenancy laws offering security of tenure to tenants and regulating the share of output that is paid as rent on farm productivity theoretically the net impact of tenancy reform is shown to be a combination of two effects a bargaining power effect and a security of tenure effect analysis of evidence on how contracts and productivity changed after a tenancy reform program was implemented in the indian state of west bengal in the late 1970s suggests that tenancy reform had a positive effect on agricultural productivity there

immigration to the land of redistribution negative perceptions about migrants in europe are driven by concerns that foreigners abuse welfare paradoxically instruments of social inclusion are becoming weapons of mass exclusion we compare evidence on welfare access and the net fiscal position of migrants with perceptions based on a largely unexploited database eu silc we find no evidence that legal migrants notably skilled migrants are net recipients of transfers from the state however there is evidence of residual dependency on non contributory transfers and self selection of unskilled migrants in the countries with the most generous welfare states alternative strategies to unbundle migration from welfare access are discussed

the effect of immigration on public finances the impact of immigration on the public finances is an important influence on public opinion this study aims to provide a thorough conceptual survey pointing out the complexities of a full understanding and the relevance of indirect effects and covering both static perspectives and longer run dynamic issues it considers simple accounting approaches which are relatively neglectful of behavioural responses but also tries to bring out the complexities in the nature of the relationship between immigration and the public exchequer that come with more sophisticated modelling of its economic effects

immigrants and welfare programmes exploring the interactions between immigrant characteristics immigrant welfare dependence and welfare policy the primary purpose of this paper is to provide a review of the papers within the economics literature that have examined the questions of immigrant welfare use and the responsiveness of immigrants to the incentives created by welfare systems while our focus is largely on papers looking at the european case we also draw on studies from the united states in particular on issues where the european literature is thin one set of papers asks whether immigrants who are more likely to use welfare are attracted to more generous welfare states the results from these papers are not clear cut another set of papers asks if immigrants use welfare more intensively than natives and if they assimilate out of or into welfare participation in most cases the unadjusted data show higher use of welfare by immigrants although for some countries for example germany this can be explained by differences in immigrants characteristics yet another set of papers finds that the rate of welfare use by existing migrants can influence the welfare use of newly arrived co nationals we illustrate some of these issues by looking at immigrant welfare use in ireland and the uk immigrants in the uk appear to use welfare more intensively than natives but the opposite appears to be the case in ireland
