disability employment and earnings an examination of heterogeneity this article uses information from an ad hoc module on disability in the 2002 uk labour force survey to identify the heterogeneity that exists within the disabled group and examine its impact on labour market outcomes after controlling for a range of personal characteristics the type severity duration and cause of the disability are found to be important determinants of employment but there is less evidence to support the influence of within group heterogeneity on earnings

dynamic multidimensional assessment of sustainability at the macro level the case of austria abstract this paper explores the issue of sustainability at the macro scale employing multi criteria decision aid mcda methods the incommensurability of values and the essentially multi dimensional and dynamic nature of sustainability challenge the use of composite measurement indices this determined the choice of mcda methods austria was chosen as a case study due to the wide availability of data especially on indicators of strong sustainability the structure of the multi criteria problem comprised the evolution of different sustainability dimensions over time the process for selecting criteria included a critical assessment of institutional sustainability agendas un eu and austrian government and theoretical recommendations after an assessment of mcda methods the naiade method demonstrated the most suitable properties for sustainability assessment the application of this outranking approach was undertaken in three separate settings long term from 1960 to 2003 medium term 1970 1995 and short term 1995 2003 with varying numbers of criteria the response of results to the addition of evaluating criteria and periods was tested the degree of credibility for accepting preference relations was also employed for sensitivity analysis according to the results of long term and medium term assessments especially in the weak sustainability setting sustainable progress is taking place in austria in the short term in the stronger sustainability setting and especially as the number of criteria increases more incomparable periods appear and trends are less determined moreover it is shown how results crucially depend on the methodological choices this is one of the first applications of the multi criteria tools to the dynamic analysis of sustainability at the macro scale

the labor market status of immigrants effects of the unemployment rate at arrival and duration of residence combining current population survey samples from november 1979 april 1983 june 1986 and june 1988 all of which included data on country of birth and year of immigration the authors examine pat

delegated portfolio management abstract a problem of screening agents with privately known forecasting abilities and reservation utilities and then eliciting truthful information from these agents once they are employed is considered for the case of risk averse agents and large principals an approximately optimal solution is constructively characterized under the assumption that payoffs are normally distributed a significant extension of the definnetti savage probability elicitation result is developed under this extension knowledge of agent preferences is not required when the underlying conditional distributions are symmetric and this fact is exploited to solve the screening problem in a mean variance formulation

scale economies in factor supplies international trade and migration this paper incorporates externalities generated by human capital into the heckscher ohlin samuelson framework to examine the patterns of international trade and migration individuals endowed with different levels of human capital choose to become either unskilled or skilled workers national scale economies with respect to human capital play an important role in endogenously determining these factor supplies and yield a number of interesting patterns of trade and migration migration could reinforce comparative advantage both skilled and unskilled workers could migrate in the same direction

risk aversion and the earnings of us immigrants and natives the literature on the earnings of natives and immigrants has heretofore ignored differences in compensating wages for job risks it is possible that the risk involved in migration may indicate a greater willingness on the part of immigrants to accept riskier jobs than natives alternatively immigrants may attempt to protect their migration investment by choosing occupations with less risk indicating a higher degree of risk aversion this paper examines differences in risk aversion between us immigrants and natives and corresponding differentials in wage premiums for job risk our analysis suggests that on average immigrants are exposed to 21 less risk than natives but receive a 25 higher risk premium the higher degree of risk aversion of immigrants and their lower exposure to risk and thus lower earnings explains 5 of the higher observed earnings of natives we also find that earlier immigrant cohorts pre 1970 are employed in riskier jobs than are recent cohorts but the difference accounts fo

a gravity model analysis of international migration to north america this study examines the influence of political economic and demographic factors on the size and composition of migration flows to north america a modified gravity model is specified and adjusted to include immigration regulations and characteristics specific to the origin and destination countries for empirical test of the model the time period of study is from 1976 1986 and 70 countries are covered for a total of 1540 observations of migration flows to canada and the usa the results reveal that the population of origin countries and the income of destination countries are two major determinants of migration to north america high population areas of asia and latin america provided a large share of the immigrants domestic restrictions on political and civil freedom in origin countries are found to significantly impair migration to north america

immigrant participation in the welfare system this paper presents a systematic analysis of immigrant participation in the us welfare system using the 1970 and 1980 us censuses in contrast to the previous studies the researchers focused on changes in welfare use across immigrant cohorts over time for a single immigrant cohort as it assimilates to the us furthermore it develops a theoretical model of the migration decision that explicitly incorporates the income insurance aspect of the us welfare system the analysis revealed that recent immigrant cohorts use the welfare system more intensively than earlier immigrant waves also the immigrant welfare participation was greater the longer an immigrant household had resided in the us and those characteristics of the immigrants country of origin were important determinants of welfare participation in addition the theoretical model of the migration decision which explicitly incorporated the presence of a welfare system in the destination country and this model could account for some of the ways in which source country characteristics were found to affect immigrant welfare participation

the unemployment experience of male immigrants in england in this paper the unemployment experience of immigrant men in the english labour market is examined using 1993 1994 data from the quarterly labour force survey of the united kingdom hypotheses proposed by chiswick 1982 are investigated for both the claimant count and the ilo measures of unemployment using logistic regression analysis our results show that recent white and nonwhite immigrant men experience much higher levels of unemployment than earlier cohorts for whites this effect is transitory whereas for nonwhites unemployment rates adjust more slowly as the duration of stay increases immigrant unemployment rates also vary considerably with country of birth

the role of the family in immigrants labor market activity an evaluation of alternative explanations comment most research on the labor market outcomes of immigrants has studied the behavior of individuals focusing primarily on the wage assimilation process or the excess returns to experience which immigrants obtain in their destination country s labor market e g barry r chiswick 1978 george j borjas 1985 recently however attention has been directed to analyzing immigrant labor market outcomes in a family context an approach which combines information about an individual s own labor market opportunities and the family context in which labor market decisions take place in a previously published paper in this review michael baker and dwayne benjamin 1997 evaluate alternative explanations for the observed labor supply patterns of canadian immigrants in the 1986 1991 period specifically when immigrant husbands arrive in canada they typically work less than comparable natives however immigrant wives work more than natives other things equal with assimilation the labor supply of immigrant husbands eventually catches up to that of natives while immigrant wives labor supply falls relative to comparable natives and is ultimately overtaken by that of natives the authors take these patterns to be most consistent with a family investment model in this scenario upon arrival husbands invest in their human capital while wives work to provide the family with liquidity during this investment period with increased time in canada husbands labor supply increases rapidly due to their growing skills in the canadian labor market while wives labor supply falls off in part because they originally took dead end jobs upon arrival in order to finance their husbands investments in human capital interestingly while most of the findings reported by baker and benjamin are consistent with the family investment model their estimated wage equations are not although they do not comment on this in discussing the appropriateness of the family investment model specifically they find similar rates of wage assimilation for husbands and wives this finding suggests roughly equal propensities to invest in one s own human capital for both groups this is contrary to the family investment hypothesis and does not match their story of dead end jobs for wives and large human capital investments of their husbands an alternative possible explanation for the patterns observed by baker and benjamin involves a simple price model in which the observed labor supply patterns reflect laborsupply responses to each spouse s wages for example the initially high but eventually falling level of wives labor supply relative to comparable natives could be a response to their husbands initially low but rising wages while this reasoning like the family investment model is broadly consistent with the data the authors conclude that the simple price model cannot be the entire explanation since in order to explain the full labor supply patterns of immigrants it would require unrealistically high labor supply elasticities and further that the assimilation patterns noted above remain even when wages of husband and wife are controlled blau school of industrial and labor relations cornell university 265 ives hall ithaca ny 14853 and nber and cesifo kahn school of industrial and labor relations cornell university 264 ives hall ithaca ny 14853 and cesifo moriarty school of industrial and labor relations cornell university ilr graduate student mailboxes ives hall ithaca ny 14853 souza faculdade de economia administracao e contabilidade university of sao paulo avenida professor luciano gualberto 908 cidade universitaria predio fea 1 sao paulo sp 05508 brazil the authors thank three anonymous referees for helpful comments and suggestions portions of this paper were written while blau and kahn were visiting scholars at the russell sage foundation to which they are grateful for research support

undocumented immigration and income inequality in the native born population of the us econometric evidence according to the theoretical models suggested by chiswick and others the growing presence of undocumented immigrants in the us should have a disequalizing effect on income distribution in the native born population however this proposition has not been subjected to empirical test here an econometric model of income inequality in native born households is constructed and census based estimates of the state distribution of undocumented immigrants are used to estimate model parameters the results show that such immigration has been disequalizing but that the impact has been small ranking behind several other socio economic variables

the impact of immigration on the human capital of natives implications of the quantity number and quality skill of immigration on the destination economy are analyzed including impacts on value added wages quasi rents rates of return and the skill distribution of the native labor force quantity quality trade offs are considered for both immigrant and native workers medium and long run labor supply responses by natives to immigrant induced changes in wage rates are shown to have second order effects which substantively affect the impacts of immigrants the impact of immigration policy depends on the quality as well as quantity of immigrants the time horizon and the speed of factor market adjustment

social security and migration with endogenous skill upgrading abstract the aim of the paper is to investigate the joint redistributive effects of migration and pensions and to reassess the sustainability issue raised in the existing economic literature the paper first develops a theoretical framework to analyse the impact of international migration on the labour market the model allows for heterogeneity across native born individuals and for migrants to affect both the wages and the education decision in the recipient country it then explicitly focuses on pensions under alternative migration scenarios the analysis shows that migration causes redistributive effects which increase across group wage inequality however the endogenous educational response by residents partially offsets the redistributive impact of migration while creating additional interest groups migration helps the financial sustainability of the pension scheme but the interaction between migration and pensions causes complex inter and intragenerational redistributive conflicts which are analysed in the paper

war and pestilence as labor market shocks u s manufacturing wage growth 1914 1919 there is not a single expert machinist in the labor market today if such a one exists he will be able to command his own wages the arkansas gazette october 22 1918 1 i introduction the possibility of a worldwide influenza pandemic in the near future is of growing concern for many countries around the globe the world bank estimates that a global influenza pandemic would cost the world economy 800 kill tens of millions of people 2 researchers at the u s centers for disease control and prevention calculate that deaths in the united states could reach 207 000 and the initial cost to the economy could approach 166 billion or roughly 1 5 of gdp 3 the u s department of health and human services paints a more dire picture up to 1 9 million dead in the united states and initial economic costs near 200 billion 4 while researchers and public officials can only speculate on the likelihood of a global influenza pandemic many of the worst case scenario predictions for a current pandemic are based on the global influenza pandemic of 1918 this global pandemic often termed the spanish flu killed 675 000 people in the united states nearly 0 8 of the 1910 population and nearly 40 million people worldwide 5 only the black death of 13481351 is estimated to have killed more people roughly 60 million over a similar time period 6 the global magnitude and spread of the 1918 influenza pandemic was exacerbated by world war i which itself is estimated to have killed roughly 10 million civilians and 9 million troops nicolson 1980 not only did the mass movement of troops from around the world lead to the spread of the disease tens of thousands of allied and central power troops died as a result of the influenza rather than combat although combat deaths in world war i did increase the mortality rates for participating countries civilian mortality rates from the 1918 influenza were typically much higher for the united states estimates of combat related troop mortalities are about one tenth that of civilian mortalities from the 1918 influenza given the magnitudes and the concurrence of both the 1918 influenza pandemic and world war i one would expect volumes of research on the economic effects of each event although there does exist a significant literature on the economic consequences of world war i rockoff 2004 the scope of published research on the economic effects of the 1918 influenza pandemic is scant 8 most research that has been done has focused on the health and economic outcomes of decedents of pandemic survivors almond 2006 keyfits and flieger 1968 and mortality differences across socioeconomic classes mamelund 2006 noymer and garenne 2000 this paper contributes to the literature on the economic effects of the 1918 influenza pandemic and world war i by exploring the influence of mortalities from these concurrent events on the growth of manufacturing wages in u s states and cities over the period 1914 1919 9 the general conceptual foundation for the paper is that ceteris paribus both of these events resulted in a large number of deaths which constituted a significant negative shock to manufacturing labor supply and thereby would have increased wages in the manufacturing sector immediately following both events a similar conceptual framework has been used in studies that explored the economic effects of the black death campbell 1997 karakacili 2004 and the effects of immigration on labor markets borjas 1987 card 1990 greenwood and mcdowell 1986 the analysis presented here is the first to separate the potential manufacturing labor market effects of world war i and the 1918 influenza this is an interesting exercise given that mortalities from the 1918 influenza were nearly ten times greater than world war i combat mortalities but world war i combat mortalities were more likely men aged roughly 18 44 prime ages for manufacturing workers

intertemporal market effect on gender earnings differentials lawyers in canada 1970 80 the conventional methodology for decomposition of cross sectional earnings differentials is extended to include a market effect on intertemporal changes in earnings and to analyse the changes in gender differentials over time the integrated cross sectional and intertemporal methodology is illustrated by a decomposition of the change in the earnings differential that occurred during the 1970s between male and female lawyers in canada an unprecedented rate of growth in the supply of lawyers during the 1970s in canada was associated with changes in the gender earnings differential in the legal profession this rapid supply growth had an almost negligible net impact on female earnings but a negative impact of 15 on the male earnings this explains the narrowing of the earnings differential by almost 30 over the decade although three fifths of the gender differential in 1970 and half of the differential in 1980 were attributable to the differences in the characteristics of the two groups these chang

the earnings of male immigrants in england evidence from the quarterly lfs in this paper we estimate earnings functions for native born and foreign born white and non white males in the english labour market using data from the quarterly labour force survey our results highlight the importance of distinguishing between native born and foreign born males when investigating the labour market experience of ethnic minorities furthermore the earnings performance amongst white immigrants varies considerably

the effect of literacy on immigrant earnings we examine the impact of literacy on immigrant earnings and the sources of lower returns to education and experience among immigrants we find that the native born literacy distribution dominates that for immigrants however the two groups obtain similar returns to literacy skills contrary to discrimination based explanations for immigrant native born earnings differentials among the university educated literacy differences account for about two thirds of the earnings gap however low returns to foreign experience have a larger impact on this differential among the less educated literacy differences and differences in the returns to experience have similar effects on the earnings differential

bayes stein estimation for portfolio analysis in portfolio analysis uncertainty about parameter values leads to suboptimal portfolio choices the resulting loss in the investor s utility is a function of the particular estimator chosen for expected returns so this is a problem of simultaneous estimation of normal means under a well specified loss function in this situation as stein has shown the clas sical sample mean is inadmissible this paper presents a simple empirical bayes estimator that should outperform the sample mean in the context of a portfolio simulation analysis shows that these bayes stein estimators provide significant gains in portfolio selection problems

social security eligibility and the labor supply of older immigrants the employment rate of native born men falls at a much faster rate than that of immigrants as the two groups approach the age of retirement the author draws on u s census data from 1960 2000 to examine how the eligibility requirements for social security benefits affect immigrants decisions to leave the labor market as they near retirement age because a person needs to have worked in the united states for at least ten years to qualify for benefits newly arrived immigrants may not yet have accumulated the requisite employment credits to do this and thus have greater employment rates than other comparably aged persons the probability that an older immigrant is employed falls once the ten year work rule is satisfied the implication of this finding is that immigration may affect the increase in retirement benefits that will inevitably occur as the baby boom generation retires

quantification of interdependencies between economic systems and ecosystem services an input output model applied to the seine estuary abstract the aim of this paper is to assess the possible contribution of an input output model towards two of the basic principles of the sustainability strategy of integrated coastal zone management iczm and post normal science according to these principles decision support tools should offer a holistic perspective and handle high uncertainty the difficulties in reaching sustainability are due partly to the prevailing use of narrow system boundary tools that are non holistic consequently they fail to capture important ecosystem services and ignore interdependencies between them to comply with the basic principles our method allows environmental assets to be evaluated in multiple units and integrates results from recent researches in natural sciences both enable coverage of interdependencies between ecosystem services thereby we enlarge input output modelling from the two conventional ecosystem services of sink and provisioning to the most vital ones the supporting services an application to the seine estuary addresses the impacts of maritime transportation infrastructures on nursery habitats for commercial fish the ecosystem services covered are life support and resource provisioning our results show that the restoration of a total of 73 7 km 2 of nursery areas over the period 2004 2015 would result in a stock of sole in 2015 that exceeds the business as usual scenario by 44 2 uncertainty range 35 9 69 9 in spite of high restoration costs the negative macro economic impact is very low however on the sector level a trade off results between nurseries and three economic sectors the quantification of such trade offs in our model is particularly useful to public participation in decision making

diverging patterns with endogenous labor migration abstract the standard neoclassical model cannot explain persistent migration flows and lack of cross country convergence when capital and labor are mobile here we present a model where both phenomena may take place assuming increasing returns and perfect capital mobility the driving forces behind labor migration are the size and the composition of the workforce the size of the workforce produces divergence a larger workforce in one country implies higher wages the wage gap induces in migration and this makes the wage gap even larger in this case migration is only beneficial for the labor importing country the evolution in the composition of the workforce due to migration may have opposite effects in one case in migration keeps the wage of skilled workers high enough to induce people to qualify for skilled jobs this improves the composition of labor in the receiving country only and it makes divergence a likely outcome in another case labor migration keeps the relative wage of unskilled workers in the rich country high enough to induce all migrants to take unskilled jobs and reduce the skilled to unskilled ratio in that country then migration is beneficial to the country which was first exporting labor

income inequality and international migration the purpose of this paper is to analyse the impact of international factor movements on the personal distribution of income in order to get clearcut results we use a simple model of trade and migration in which there are two traded goods and three factors for any given country one of the traded goods corresponds to exports and the other to imports the three factors include capital and two types of labour skilled and unskilled we focus mainly on the alternative results of international migration of the two types of labour the geographical focus is worldwide excerpt

economic effects of immigrants on native and foreign born workers complementarity substitutability and other channels of influence the authors use standard metropolitan statistical area smsa data constructed from 1980 census microdata files and other sources to estimate a structural model of native foreign born labor demand and labor supply which distinguishes the effects upon real wages of each type of labor and on the employment of natives the authors specify econometrically estimate and simulate the structural model which incorporates not only a production structure channel through which immigrants influence area real wages and employment but also demand and native labor supply channels it is noted that while these are not the only channels through which immigrants may affect native workers the model nonetheless constitutes a step in the direction of a general equilibrium approach in the production structure channel immigrants and natives are found to be substitutes in production immigration lowers foreign born wage rates and leads to lower wages for natives the negative effects of the production channel usually are ameliorated through the demand channel further immigrants add to local demand through their earnings and potentially through non labor income while also lowering unit costs and local prices which enhances real incomes and potentially net exports and thus the demands for local output and area labor the author discusses findings of interest from the simulation results based upon an analysis of all areas

trade theory distribution of income and immigration this paper examines the impact of mass immigration utilizing the analytical framework of so called trade theory as such its emphasis is on general equilibrium effects and on the constraints imposed by the openness of the economy on such effects the analysis will center on the distributional impact of unskilled labor immigration excerpt

wage mobility of foreign born workers in the united states this paper presents new evidence on whether foreign born workers assimilate while the existing literature focuses on the convergence divergence of average wages this study extends the analysis to the distribution of wages by looking at wage mobility we measure the foreign native gap in year to year transition probabilities from one decile group to another of a wage distribution where the deciles are determined by native samples our results based on the current population survey for 1996 2008 suggest that immigrants in middle and bottom decile groups who are the majority of immigrants tend to fall behind relative to natives in the same decile groups

immigrants minorities and labor market competition this paper investigates the extent of labor market competition among immigrants minorities and the native population an analysis of 1980 u s census data reveals that immigrants tend to be substitutes for some labor market groups and complements for others the effects of shifts in immigrant supply on the earnings of native born men are however very small on the other hand increases in the supply of immigrants do have a sizable impact on the earnings of immigrants themselves an increase of 10 percent in the supply of immigrants for example reduces the immigrant wage by about 10 percent

on the macroeconomic and welfare effects of illegal immigration abstract this paper uses a dynamic general equilibrium model with labor market frictions to explore the economic consequences of illegal immigration in the baseline model native workers and illegal foreign workers compete for jobs in the same market but serve as imperfect substitutes in production the calibrated model generates a u shaped relationship between long run domestic consumption and the population share of illegal immigrants after taking into account both consumption and leisure i found that an increase in illegal immigration can generate significant welfare gains for the natives the baseline model is then extended to include heterogeneous workers in the domestic population

some economic determinants of third world professional immigration to the united states 1972 87 abstract we estimate reduced form equations for immigration to the united states by engineers natural and social scientists and physicians from 18 third world countries explanatory variables include income real gdp growth graduation in the united states and study in each country of origin additional explanatory variables are foreign student enrollment in the united states lagged immigration total immigration from each country and a dummy variable which accounts for implementation of restrictions on permanent visas in 1972 1973 results generally conform to expectations but differ across occupations and with model specification most income statistics are unexpected however and the strong correlation of us income with graduation in the united states suggests that there is a simultaneity problem in models which include income because immigration appears to respond to labor shortages in the united states and surpluses in countries of origin our results suggest that us immigration quotas have not prevented third world professionals from responding to economic incentives

should germany have built a new wall macroeconomic lessons from the 2015 18 refugee wave abstract in 2015 2016 germany experienced a wave of predominantly low skilled refugee immigration we evaluate its macroeconomic and distributional effects using a quantitative overlapping generations model calibrated using german micro data to replicate education and productivity differentials between foreign born and native workers workers are modelled as imperfect substitutes in aggregate production leading to endogenous wage differentials we simulate the dynamic effects of this refugee wave with specific focus on the welfare impact on low skilled natives our results indicate that the small losses this group suffers can be compensated by welfare gains of other parts of the native population

immigrant earnings age at immigration matters a correlation between age at immigration and earnings is observed in canadian census data the evidence supports three underlying sources of the effect first work expe rience in the source country yields virtually no return in the host country second the return to education varies with age at immigration and finally an acculturation effect is observed for immigrants who are visible minorities or whose mother tongue is not english further it is found that educational attainment and relatedly earnings vary systematically across age at immigration with those arriving around age 15 to 18 obtaining fewer years of education

migration of professionals from fiji to new zealand a reduced form supply demand model abstract in this study we estimate a reduced form equation for migration of highly skilled and professionally trained workers from fiji to new zealand during 1987 1990 explanatory variables include previous period s migrants occupational income in new zealand the supply of graduates in new zealand and political instability in fiji using a reduced form supply demand model to estimate the determinants of migration the study finds that the number of professional migrants from fiji was significantly and positively related to previous year s migrants the real income in new zealand and political instability in fiji

toward consilience between biology and economics the contribution of ecological economics abstract during its ten year history ecological economics has made a real difference in the way economists look at the natural world and in the way biologists look at the economy in this survey article we examine the contributions to the journal in terms of e o wilson s concept of consilience that is his argument that the methods and assumptions of any field of study should be consistent with the known and accepted facts in other disciplines in particular we examine the contributions of ecological economics to reconciling the economic theory of the consumer and producer with biophysical reality

the economic situation of first and second generation immigrants in france germany and the united kingdom a central concern about immigration is the integration into the labour market not only of the first generation but also of subsequent generations little comparative work exists for europe s largest economies france germany and the uk have all become perhaps unwittingly countries with large immigrant populations albeit with very different ethnic compositions today the descendants of these immigrants live and work in their parents destination countries this article presents and discusses comparative evidence on the performance of first and second generation immigrants in these countries in terms of education earnings and employment it is widely believed that many european countries have a serious problem with the integration of immigrants and their children leed 2006 many northern european countries have accumulated sizeable populations of immigrants but the lack of longterm strategies and policies to integrate these into societal structures and the labour market is often cited as one reason for social and economic exclusion of the children of these immigrants in the past decade southern european countries such as spain and italy have experienced similar if not larger immigrations than the large northern european economies france germany and the uk in the late 1950s to early 1970s again it seems that there is little thought devoted to long term strategies for immigrants and their descendants the experience of those countries that had large scale immigration in the last half of the twentieth century should be of importance for devising future immigration and integration policies however there is rather little hard evidence in the literature about the relative position of immigrants and their descendants in these countries in a manner that allows comparisons to be made in this article we aim to provide a comparative study of a number of outcomes education earnings and employment of both first and second generation immigrants of different origins in the three largest european economies france germany and the uk

crossing the border self selection earnings and individual migration decisions many empirical studies on the determinants of international migration flows rely exclusively on macro data and do not account for migrants self selection we analyze a very interesting episode in international migration for which we are able to gather individual level data covering all relevant countries namely the exodus of ecuadorians to spain and the us in the aftermath of the economic collapse of 1999 specifically we produce selection corrected predictions of counterfactual individual earnings and use them to estimate a discrete choice migration equation that allows for correlated errors across destinations and a rich structure of migration costs we find that earnings significantly shape individual migration decisions even in an episode in which ecuadorians mostly chose spain where earnings were lower than in the us and they contribute to explaining the observed composition of migration flows moreover our estimates show that changes in earnings at a particular destination have a larger effect on destination choice conditional on migration than on the scale of migration

credit constraints and the labour supply of immigrant families in canada the hours of work decisions in immigrant and nonimmigrant families are compared using an intertemporal labor supply model estimated over data from the 1981 and 1991 census of canada surveys the family investment hypothesis is evaluated the hypothesis states that the immigrant family is unable to borrow in the first years after migration and that the immigrant wife responds by working longer hours so as to support family consumption and her husband s labor market adjustment the empirical evidence in general supports the hypothesis since credit constraints are found to significantly distort the labor supply decisions of recently arrived immigrant families

operationalizing sustainable development dynamic ecological economic models abstract since the mid eighties a vast literature has evolved around the concept of sustainable development it shows a wide support for changes in policy making and decision making for instance to integrate environmental interests in national and international political processes remarkably recommendations of contours and new elements of research methods and policy analysis for sustainable development are rare although this is just as essential as the renewed attention for the political dimension a clear view on how to use and change adequately existing techniques and models for sustainable development will contribute to a more satisfactory operationalization of it this paper examines the implications of ecologically sustainable economic development for integrated dynamic modelling after a concise discussion of sustainable development it is suggested that five concepts are central to it intergenerational equity the regional scale multiple use long term uncertainty and economic ecological integration the discussion of each of these issues is focused on the implications for model elements and uses thereby old ideas are reviewed and new ones are proposed the aim is not to come up with a rigid framework for dealing with sustainable development but rather to suggest which alternatives are available to deal with the central concepts although in a section on economic ecological integration general requirements for dynamic economic ecological models are mentioned explicitly in order to offer a general frame of reference these requirements are fairly general and may be taken up in ensuing discussions of the methodological aspects related to sustainable development the main conclusions are the following we view economic ecological integration in the sense of combining processes instead of one process and a variable to deal with intergenerational equity one may choose objectives various constraints or a combination of both for regional models one may consider various types of conditions on cross boundary flows and external factors of regional processes multiple use can be modelled as an intermediate stage between single resource models with a partial view and complex models with a general view sensitivity probability and scenario analyses can be used to deal partially with the various types of long term uncertainty although this remains difficult for the very important class of unexpected events or catastrophes such surprises can at best be turned into risk by scenario analyses and examination of dynamic behaviour of the system as a whole

the dynamics of portfolio management contracts we consider the multiperiod relationship between a client and a portfolio manager and the resulting problem of motivating a manager of unknown ability to acquire valuable information we explore the contractual forms and the optimal retention policy of the client and find that the optimal initial set of contracts features a smaller performance based fee component paid to the manager than in a first best contract and the contract choice elicits only partial information about the manager as a result ex post performance measurement is critical to future recontracting in general managers are retained only if the returns on their portfolio exceed the benchmark by an appropriate amount article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

trade and the environment from a southern perspective the relationship between free trade and the environment is one of the main issues of contention between environmental and ecological economics environmental economics assumes a positive relationship between free trade economic growth and environmental policies environmental externalities may cause important damage however trade is not to be blamed for this instead the fault lies with policy inadequacies at the national level on the other hand some ecological economists criticise the assumptions of environmental economics especially the immobility of production factors and the positive correlation between income and environmental quality they plead for measures to prevent deterioration of northern environmental standards in a race to the bottom due to ecological dumping from the south in this paper we argue that neither environmental economics nor northern ecological economics take into account the structural conditions determining the international trade system based on some new empirical evidence on material flows we stress the notion of environmental cost shifting if physical and political ecology perspectives are adopted a southern approach to the trade and environment issue may arise 2001 elsevier science b v all rights reserved

the impact of host country schooling on earnings a study of male immigrants in the united states immigrants in the united states who acquire u s schooling earn higher wages than other immigrants using data from the u s censuses and the national longitudinal survey of youth we show that this wage advantage results from both greater educational attainment and higher returns to education the higher returns are not the consequence of ability bias or greater english proficiency of those who acquire u s schooling returns to years of non u s education are higher for immigrants who complete their schooling in the united states consistent with the view that u s schooling upgrades or certifies education received in the source country for those without u s schooling returns are higher for immigrants from highly developed countries and countries for which english is an official language

multicriteria decision analysis and environmental economics an approximation abstract a multicriteria approach to address basic problems in environmental economics is proposed in this paper the methodology is underpinned by the wellknown multicriteria method called compromise programming together with some recent results relating the compromise sets with the traditional optimisation of the utility functions to illustrate the proposed methodology the following two cases are suggested 1 the reconciliation between economic environmental as well as recreational objectives inherent to the management of an environmental asset such as forestry system and 2 its application to the appraisal of environmental improvements or damages when nonmonetary objectives are involved

adverse risk incentives and the design of performance bases contracts this paper uses option pricing theory to value and analyze many performance based fee contracts that are currently in use a potential problem with some of these contracts is that they may induce portfolio managers to adversely alter the risk of the portfolios they manage the paper is prescriptive in that it presents conditions for contract parameters that provide proper risk incentives for classes of investment strategies for buy and hold and rebalancing strategies adverse risk incentives are avoided when the penalties for poor performance outweigh the rewards for good performance

migration and labour markets in oecd countries a panel cointegration approach this article examines the interaction between immigration and the host labour market of 14 organization for economic co operation and development oecd countries using nonstationary panel data methodology we estimate a trivariate vector error correction model vecm and derive causality tests to simultaneously assess the long and short term macroeconomic impact of newcomers on wages and unemployment levels in the host country the results suggest that an increase of migrants is likely to increase wages in the destination countries in the short run but to increase them in the long run there is no evidence of adverse effects on unemployment due to immigration in short and long term except for anglo saxon countries in the short term our findings also show that immigration is conditioned by levels of unemployment and wages especially in anglo saxon countries

illegal immigration in an efficiency wage model abstract this paper studies illegal immigration using an efficiency wage dual labor market model the illegal immigrants are endogenously sorted completely or incompletely into secondary labor markets the effects of immigration on native workers are more complex than in standard models of factor mobility as illegals first enter the country natives may gain because the number of primary sector jobs rises with enough illegals in the country natives are hurt because the migrants increasingly take those primary sector jobs enforcing immigration laws by deporting migrants who work in primary sector jobs is pareto superior to other forms of enforcement

do when and where matter initial labor market conditions and immigrant earnings this article investigates the long term effects on immigrant earnings and employment of labour market conditions encountered upon arrival we find that early earnings assimilation depends crucially on a favourable national labour market exposure to high local unemployment rates also affects individuals for at least ten years to handle the issue of selective migration we compare refugees entering sweden during a severe and unexpected recession to refugees arriving during a preceding economic boom the analysis of effects at the local level exploits a governmental refugee settlement policy to get exogenous variation in local labour market conditions

assimilation changes in cohort quality and the earnings of immigrants this paper reexamines the empirical basis for two facts that seem to be found in most cross section studies of immigrant earnings 1 the earnings of immigrants grow rapidly as they assimilate into the united states and 2 this rapid growth leads to many immigrants overtaking the earnings of the natives within 10 15 years after immigration using the 1970 and 1980 u s censuses this paper studies the earnings growth experienced by specific immigrant cohorts during the period 1970 80 it is found that within cohort growth is significantly smaller than the growth predicted by cross section regressions for most immigrant groups this differential is consistent with the hypothesis that there has been a secular decline in the quality of immigrants admitted to the united states

the ramaswami proposition and the choice among labor capital and technology flows abstract this paper examines the choice between labor and capital flows in the context of a one good two country model where the two countries differ in their levels of disembodied technology in contrast to the ramaswami proposition it is shown that a country may prefer an optimal outflow of its abundant factor to an optimal inflow of its scarce factor it is also shown that for sufficiently small differences in technology the labor rich technology inferior country will benefit more from an optimal outflow of labor than from a gift of superior technology

immigrant and emigrant earnings a longitudinal study this paper analyzes the relationship between earnings and the extent of assimilation cohort quality change and return migration experienced by the foreign born population the study uses the longitudinal data available in the survey of natural and social scientists and engineers the analysis reveals that there was a sizable decline in the skills of this population over the last two decades in addition the study shows that return migration is more likely among immigrants who did not perform well in the u s labor market

human capital investment and migration in an integrated europe the short and longer term regional consequences of migration for european aggregate supply are examined in a simple model in which human capital enters the production function externally the planner chooses a reallocation of population across east and west that cannot be replicated by the market without taxes or subsidies the market solution in this model with free migration is always associated with an efficiency loss and might lead to the mezzogiorno syndrome in the east excerpt

immigration and wages evidence from construction to identify relative wage impacts of immigration we make use of certification and licensing requirements in the norwegian construction sector that give rise to exogenous variation in immigrant employment shares across trades individual panel data reveal substantially lower wage growth for workers in trades with rising immigrant employment than for other workers selective attrition from the sector masks the causal wage impact unless accounted for by individual fixed effects for low and semi skilled workers effects of new immigration are comparable for natives and older immigrant cohorts consistent with perfect substitutability between native and immigrant labor within trade finally we present evidence that immigration reduces price inflation as price increases over the sample period were significantly lower in activities with growth in the immigrant share than in activities with no or small change in immigrant employment

explaining differences in job retention between alien and nonalien workers after an in company training this study focuses on the job retention of unemployed workers after they attended a subsidized in company training programme in flanders using a new large scale dataset of the flemish labour exchange we look for differences in the probability of employment between aliens and nonaliens during the 36 months following their on the job training we further investigate whether differences persist after controlling for several socio economic characteristics and labour market related variables estimating a modified probit model we find that on average being an alien lowers the probability of employment after training by approximately 15 this effect reduces to 10 when controlling for other variables the effect of education on a trainee s employment chances differs for aliens and nonaliens aliens have a markedly lower return on investment in education good language skills and a longer in company training period also increase employment probability but more so for aliens other control variables do not

are refugees different from economic immigrants some empirical evidence on the heterogeneity of immigrant groups in the united states this paper analyzes how the implicit difference in time horizons between refugees and economic immigrants affects subsequent human capital investments and wage assimilation the analysis uses the 1980 and 1990 integrated public use samples of the census to study labor market outcomes of immigrants who arrived in the united states from 1975 to 1980 i find that in 1980 refugee immigrants in this cohort earned 6 less and worked 14 fewer hours than economic immigrants both had approximately the same level of english skills the two immigrant groups had made substantial gains by 1990 however refugees had made greater gains in fact the labor market outcomes of refugee immigrants surpassed those of economic immigrants in 1990 refugees from the 1975 1980 arrival cohort earned 20 more worked 4 more hours and improved their english skills by 11 relative to economic immigrants the higher rates of human capital accumulation for refugee immigrants contribute to these findings

an assessment of the human capital content of international migrants an application to us immigration mcdowell j m and singell l d jr 1993 an assessment of the human capital content of international migrants an application to us immigration reg studies 27 351 363 numerous studies have examined the flow of international migrants generally these studies measure the extent or magnitude of international migration by use of a simple numerical count this paper extends this analysis by providing a methodology for adding an economic dimension to the measure of the magnitude of international migration an earnings equation approach is used to attach an economic value to immigration applying our methodology to us immigration we find considerable variation across source regions in the value of immigrants moreover we find that simply comparing initial earnings without controlling for differences in the characteristics and migration patterns of immigrants from the various source regions can misrepresent the relative earnings potential or value of migrants mcdowell j m et singell l d jr 1993 un

the effect of naturalization on wage growth a panel study of young male immigrants for young male immigrants naturalization facilitates assimilation into the u s labor market following naturalization immigrants gain access to public sector white collar and union jobs and wage growth accelerates consistent with removal of employment barriers the faster wage growth of immigrants who naturalize might alternatively result from greater human capital investment prior to naturalization stemming from a long term commitment to u s labor markets but there is no evidence that wage growth accelerates or the distribution of jobs improves until citizenship is attained finally the gains from naturalization are greater for immigrants from less developed countries and persist when we control for unobserved productivity

immigrant earnings relative to what the importance of earnings function specification and comparison points immigrant relative earnings estimates are sensitive to the choice of comparison point and the specification of earnings non sample mean comparisons borjas 1985 understate relative earnings simple earnings specifications linear education quadratic experience overstate relative earnings for both poorly and well educated immigrants specifications which ignore omitted variables understate the relative earnings of poorly educated immigrants and overstate those of well educated ones although measures of assimilation and changes in immigrant quality are insensitive to earnings specification they indicate strong earnings growth for post 1964 immigrants an overall decrease in immigrant quality and an increase in mexican immigrant quality

the effect of minimum wages on immigrants employment and earnings this study examines how minimum wage laws affect the employment and earnings of low skilled immigrants and natives in the u s minimum wage increases might have larger effects among low skilled immigrants than among natives because on average immigrants earn less than natives due to lower levels of education limited english skills and less social capital results based on data from the current population survey for the years 1994 2005 do not indicate that minimum wages have adverse employment effects among adult immigrants or natives who did not complete high school however low skilled immigrants may have been discouraged from settling in states that set wage floors substantially above the federal minimum jel classifications j23 j38 j15

immigrants in the u s labor market 1940 80 this paper explores the extent and causes of the decline in immigrant skills in the united states during the postwar period prior to 1965 immigration to the united states was guided by the national origins quota system this visa allocation system awarded visas to countries based on the representation of the national origin group in the u s population as of 1920 the 1965 amendments abolished the national origins formula thus redistributing visas across source countries and established a system where visas are mainly given to relatives of u s citizens or residents the empirical analysis shows that a single factor the changing national origin mix of the immigrant flow is mainly responsible for the decline in immigrant skills excerpt

motivations of south african emigrants reasons for emigration from south africa particularly of professionals are investigated using data from a recent survey the authors conclude that although direct fear of potential violence is not a major factor emigrants are concerned about changes in living standards resulting from economic problems or changes in government structure annotation

access to citizenship and the economic assimilation of immigrants immigrants often have lower employment rates and earnings than natives our empirical analysis relies on two reforms generating exogenous variation in the waiting time for citizenship we find that faster access to citizenship improves the economic situation of immigrant women especially their labour market attachment with higher employment rates longer working hours and more stable jobs immigrants also invest more in host country specific skills like language and vocational training faster access to citizenship seems a powerful policy instrument to boost economic integration in countries with traditionally restrictive citizenship policies

international portfolio diversification with estimation risk international portfolio diversification has long been advocated as a way of enhancing average returns while reducing portfolio risk for the investor who considers diversifying into foreign securities this proposition however relies on the assumption that the required inputs to the classical mean variance analysis are known with certainty typically expected returns variances and covariances are simply replaced by their ex post sample values and the optimal portfolio is derived without mentioning the uncertainty inherent in these parameter values but the rational investor should take this uncertainty into account when forming expectations and probably will consider estimators that are less subject to estimation error than the classical sample mean this paper investigates alternative estimators of expected returns and their implications for the alleged gains from diversification an important observation is the crucial influence that errors in estimating expected returns have on portfolio analysis a closer examiprevious studies of international portfolio diversification have relied on ex post meanvariance analysis without considering the problem of estimation risk typically past averages are substituted for expected returns and no allowance is made for the uncertainty inherent in these parameter values first i demonstrate the shortcomings of such an approach and second i investigate another method of estimating expected returns initially proposed by stein by shrinking the sample averages toward a common mean i find that the out of sample performance of the optimal portfolio is substantially increased one of the implications of this method is that the classical conclusions vastly overestimate the possible gains in average returns instead benefits from diversification are more likely to accrue from a reduction in risk this paper draws on part of my dissertation at the university of chicago i am grateful to arnold zellner michael mussa george constantinides and especially john bilson for useful discussions and comments numerous improvements were also suggested by the referee this research received the generous financial support of the college interuniversitaire d etudes doctorales dans les sciences du management

new evidence on the economic progress of foreign born men in the 1970s and 1980s this study examines the economic progress of foreign born men in the united states europeans entered the united states with relatively high wages and earned wages comparable to natives over their life course japanese korean and chinese men entered with lower wages but quickly caught up with u s born workers mexicans and central americans entered with low wages and the wage gap between themselves and u s born workers has not shrunk disparities in completed years of education and whether education was received in the united states can explain a large share of the differences in the level of wages for immigrants from some countries it is found that more highly educated men assimilate more quickly the rate of economic progress has not improved for more recent arrivals from any country but this is most problematic among mexicans and central americans because of their relatively low rates of wage growth excerpt

factor rewards and the international migration of unskilled labor a model with capital mobility abstract conventional economic wisdom holds that the migration of unskilled labor from less developed countries to neighboring developed countries should be expected to narrow the wage gap between those countries and thereby reduce the incentive for further migration if capital is mobile internationally this reasoning may be inappropriate instead emigration of unskilled labor out of the less developed country provides an incentive for capital to leave the country too as a consequence wage rates move in the same direction in each country and the gap between wage rates across countries even may increase

job search and immigrant assimilation an earnings frontier approach this study examines labor market assimilation by measuring the information utilized by immigrants during job search assimilation is assumed to occur whenever such information increases with length of residence in the united states and repeated job searches the authors assert that information utilized during job search reduces differentials between actual and potential maximum attainable earnings coauthors are henry w herzog jr richard a hofler and alan m schlottmann copyright 1992 by mit press

optimal contracts in a continuous time delegated portfolio management problem this article studies the contracting problem between an individual investor and a professional portfolio manager in a continuous time principal agent framework optimal contracts are obtained in closed form these contracts are of a symmetric form and suggest that a portfolio manager should receive a fixed fee a fraction of the total assets under management plus a bonus or a penalty depending upon the portfolio s excess return relative to a benchmark portfolio the appropriate benchmark portfolio is an active index that contains risky assets where the number of shares invested in each asset can vary over time rather than a passive index in which the number of shares invested in each asset remains constant over time fund managers compensation schemes in a delegated portfolio management setting have been of special interest to both academics and practitioners academic interest stems in part from the rapid growth of managed funds over the last two decades gompers and metrick 1998 report that by december 1996 mutual funds pension funds and other financial intermediaries held discretional control over more than half of the u s equity market it is thus of importance to study the impact of institutional trading on asset prices and to integrate into one model both asset pricing and delegated portfolio management compensation as advocated by brennan 1993 allen and santomero 1997 and allen 2001 it is also important to understand the relationship between a manager s trading strategies and his implicit incentives or career concerns see e g brown harlow and starks 1996 brown goetzmann and park 1997 chevalier and ellison 1999 and chen and pennacchi 2000 these concerns include internal promotion from a small to a large fund higher outside offers and the flow of money through the fund under management 1 the importance of fund manager compensation is also underscored by congressional passage in 1970 of the amendment to

the parallel market of illegal aliens a computational approach abstract this paper develops the notion of illegal aliens as a parallel market in coexistence with the regular market of legal labor in the presence of both price controls on legal labor by minimum wage legislation and quantity controls on illegal aliens by immigration laws illegal aliens involve not only rural urban migration but also tax evasion and deportation costs we develop an analytical equilibrium structure which links markets for legal labor and illegal aliens illustrate how much an equilibrium can be computed and explore some implications of the linkage using united states data

trade liberalization economic specialization and the environment abstract a great deal has been written and a great deal of debate has raged on the effects of international trade and trade liberalization on the environment given that it is only recently that the general agreement on tariffs and trade has begun to address the interdependence of the international economy and the international environment in a systematic way it is likely that the debate will continue for quite some time it will be argued that the economic case for there being benign environmental consequences associated with trade liberalization is flawed in important ways this is due to statistical empirical and conceptual issues which affect the estimation of such effects moreover it will be argued that despite the intensity of the debate the effects of international trade on the environment have in fact only been addressed in an incidental manner rather the debate has concentrated on factors that may coexist with trade but not on the role of trade itself this has served to obscure the more fundamental environmental effects of trade liberalization through the homogenization and specialization of ecosystems

historical roots for ecological economics biophysical versus allocative approaches abstract a number of economists today are aware that the results of their science are more or less at variance with concrete fact and are alive to the necessity of perfecting it they go wrong rather in their choice of means to that end they try obstinately to get from their science alone the materials they know are needed for a closer approximation to fact whereas they should resort to other sciences and go into them thoroughly not just incidentally for their bearing on the given economic problem until economic science is much farther advanced economic principles are less important to the economists than the reciprocal bearings of the results of economics and the results of the other social sciences many economists are paying no attention to such interrelations for mastery of them is a long and fatiguing task requiring an extensive knowledge of facts whereas anyone with a little imagination a pen and a few reams of paper can relieve himself of a chat on principles pareto 1935 para 2022

the use of transfer payments by immigrants this paper uses data from the 1976 survey of income and education to compare the receipt of transfers by families headed by male and female immigrants and those headed by native born americans the average level of transfers is found to be considerably higher among families headed by immigrants but this is almost entirely the result of the higher average age of family members among the immigrant group a reflection of the large inflows of immigrants into the u s during the pre 1924 period when age and other factors are held constant immigrant families are found to be considerably less likely to rely on welfare than native families and their receipts from social insurance programs are found to be only slightly higher

pricing the ecosystem and taxing ecosystem services a general equilibrium approach abstract in an integrated dynamic general equilibrium model of the economy and the ecosystem humans and other species compete for land and prey biomass each submodel exhibits a price driven competitive allocation mechanism and the endogenously determined habitat is either openly accessible or privately owned in both scenarios specific corrective taxes or subsidies are needed to internalize ecosystem externalities an open access habitat causes additional inefficiencies through diverging prices for biomass and land in both subsystems values of all ecosystem components are determined in an efficient steady state clarifying the role and the interplay of ecosystem prices and economic prices

productivity of highly skilled immigrants economists in the postwar period larry d singell jr prior work finds declining immigrant quality in the postwar period that is linked to source country and skill composition changes associated with the 1965 immigration act this paper uses a unique panel of foreign and native born american economic association members to show that the highly skilled experienced a similar shift away from european migrants toward those from asia however the findings do not indicate that this change in source country composition has been accompanied by a decline in quality rather the most recent cohorts of foreign born economists appear to be more productive than their native counterparts jel j61 i introduction this article is the first systematic analysis of the attributes and abilities of foreign born u s economists since a descriptive study of the brain drain by grubel and scott 1967 it also provides some of the first formal evidence for the largely theoretical proposition in earlier work by bhagwati and rodriquez 1975 that the united states draws the best skilled workers from abroad however recent immigration literature has not focused on the brain drain but has generated considerable debate concerning whether the 1965 immigration and nationality act has reduced the skill quality of u s immigrants in particular descriptive evidence in borjas 1987 and greenwood 1983 respectively indicates that the 1965 law shifted the composition of u s immigrants toward non european nations and increased the number of low skilled migrants to the united states our article extends this work by examining whether there has been a post 1965 change in the source country mix of ph d economists and whether such chan ges impact the productivity of the foreign born in comparison to their native counterparts most empirical studies of immigrant productivity have focused on earnings early cross sectional studies of immigrant earnings including chiswick 1978a concluded that the age earnings profile of immigrants is steeper than that of comparable native born workers and though initially lower crosses the native profile 10 to 15 years after immigration these results are consistent with the widely held belief that the immigration process self selects the highly motivated and industrious from their respective source countries thus immigrants although they initially enter the united states with relatively low levels of human capital eventually become more productive than their native counterparts more recent work by borjas 1985 1987 has contested these conclusions arguing that it is not possible to separately identify assimilation and cohort effects using a single cross sectional data set in particular the positive correlation between earnings and years since migration in cross sectional data may be due to immigrant assimilation or a cohort effect that arises from the declining skill quality of more recent immigrant groups borjas combines multiple cross sectional data sets to separately identify assimilation and cohort effects and finds evidence indicating that earlier cohorts of immigrants do relatively better than both natives and more recent immigrant cohorts suggesting a decline in immigrant quality although chiswick 1986 challenges the contention of declining immigrant quality and funkhouser and trejo 1995 find evidence that immigrant quality may have increased during the 1980s borjas 1995 contends that the empirical evidence consistently shows that immigrant quality has declined for most of the postwar period however the decline in immigrant quality has not necessarily been found within specific groups of immigrants in particular greenwood and mcdowell 1986 find that the change in skill quality is related to the shift in the source country composition of immigrants away from european nations toward those from asia and latin american after the 1965 immigration act thus explanations for the relatively poor performance of recent immigrants including those in lalonde and topel 1991 1992 and borjas 1992 focus on the post 1965 changes in the incentives to migrate to the united states that have increased the number of low skilled non european immigrants

gender source country characteristics and labor market assimilation among immigrants abstract using 1980 2000 census data to study the impact of source country characteristics on married adult immigrants labor supply assimilation profiles we find that immigrant women from countries with high female labor supply persistently work more than those from low female supply countries while both groups of women work less than comparable natives on arrival women from high female participation countries eventually close the gap with natives entirely and women from low female labor supply countries eliminate most of it men s labor supply is unaffected by source country female participation suggesting that the findings on women reflect notions of gender roles

delegated portfolio management and optimal allocation of portfolio managers in this article we investigate whether the application of the mean variance framework on portfolio manager allocation offers any out of sample benefits compared to a naive strategy of equal weighting based on an exclusive data set of high net worth hnw investors we utilize a wide variety of methodologies to estimate the input parameters including exponentially weighted moving average ewma generalized autoregressive conditional heteroscedasticity garch and bayes stein shrinkage estimation we apply nine different mean variance models but find that none of these present any consistent benefit over a naive strategy of equal weighting

the work effort and the consumption of immigrants as a function of their assimilation positive self selection has been used to explain the superior economic performance of some immigrant groups even if immigrants and natives are identical however the former face different incentives in particular they bear costs not incurred by natives including monetary costs of moving costs of staying in touch with family and obligations to those left behind nonmonetary costs include stress and loss of location specific human capital the focus of this paper is on how these costs influence the decisions of immigrants relative to those of natives particular attention is given to the role of assimilation

a political economic analysis of labor migration and income redistribution we present a two country political economic model of income redistribution with internationally mobile labor migration can be exogenous and or endogenous i e determined by labor income differentials political influence is determined by the size and homogeneity of the groups where the latter can be affected by immigration we show that immigration can increase the transfers to and the income of the mobile group we also investigate the possibility of migration regulation tax transfer policy competition and coordination and finally coordination of regulation policies it is shown that the selection of any of those regimes will depend on the particular distribution of political influence among the relevant social groups in the two countries

on the wage growth of immigrants israel 1990 2000 this paper develops a descriptive methodology for the analysis of wage growth of immigrants that is based on human capital theory the sources of the wage growth are 1 the rise of the return to imported human capital 2 the impact of accumulated experience in the host country and 3 the mobility up the occupational ladder in the host country the model implies a nonlinear wage function that includes interactions between imported skills and local wage growth using data on native israelis and immigrants from the former soviet union of israel we estimate wage equations jointly for the two groups we find that upon arrival immigrants receive non return for imported skills in the ten years following arrival wages of highly skilled immigrants grow at 8 percent a year rising prices of skills occupational transitions accumulated experience in israel and an economy wide rise in wages account for 3 4 1 1 1 5 and 1 5 percent each in the long run the return for schooling converges to 0 027 substantially below the 0 069 return for natives we do not reject the hypothesis that the return for experience converges to that of natives and that immigrants receive a higher return for their unmeasured skills we find that there is some downgrading in the occupational distribution of immigrants relative to that of natives moreover the average wages of immigrants approach but do not converge to the wages of comparable natives the main reason for this is the low return to their imported skills jel j24 j31 j60
