social insurance and occupational mobility this paper studies how insurance from progressive taxation improves the matching of workers to occupations we propose an equilibrium dynamic assignment model to illustrate how social insurance encourages mobility workers experiment to find their best occupational fit in a process filled with uncertainty risk aversion and limited earnings insurance induce workers to remain in unfitting occupations we estimate the model using microdata from the united states and germany higher earnings uncertainty explains the u s higher mobility rate when workers in the united states enjoy germany s higher progressivity mobility rises output and welfare gains are large

the impact of immigration comparing two global eras summary this paper asks whether history can inform modern debate about immigration s impact on high wage economies it examines the relationship between migration s labor market impact and capital flows before 1914 the first global era it then assesses the effects of immigration on wages and employment with and without international capital mobility today in the second global era it then explores the links between these economic relationships welfare burdens and immigration policy it concludes with an explanation for the apparent difference in immigration s impact in the two global eras and thus on policy

economic dynamics in the malthusian era evidence from the 1609 spanish expulsion of the moriscos we investigate economic dynamics in the malthusian era using the 1609 expulsion of moriscos from spain sharp population declines in former morisco districts were accompanied by decreased output and increased per capita output while these short run results are consistent with standard malthusian predictions malthusian convergence was delayed up to 1786 in former morisco districts archival sources and historical accounts suggest extractive institutions and cultural differences may have contributed to delayed convergence in population and output per capita this historic episode provides an unusually rich setting to examine malthusian dynamics highlighting the potential for sustained differences in per capita output in the malthusian era

intersectoral labor immobility sectoral comovement and news shocks sectoral comovement of output and hours worked is a prominent feature of business cycle data however most two sector neoclassical models fail to generate this sectoral comovement we construct and estimate a two sector neoclassical dynamic stochastic general equilibrium dgse model generating sectoral comovement in response to both anticipated and unanticipated shocks the key to our model s success is a significant degree of intersectoral labor immobility which we estimate using data on sectoral hours worked furthermore we demonstrate that imperfect intersectoral labor mobility provides a better explanation for the sectoral comovement than an alternative model emphasizing the role of labor supply wealth effects

three million foreigners three million unemployed immigration flows and the labour market in france this paper investigates the effect of the flows of immigrant workers on the french labour market from the mid 1970s to the mid 1990s using a system of equations for unemployment labour force participation the real wage and the immigration rate it is shown that in the long run both legal and amnestied immigrant workers and immigrant families lower the unemployment rate permanently in the short run the arrival of immigrants increases unemployment slightly with an impact effect similar to that of an increase in domestic labour force participation the composition of immigration flows matters and the results indicate that the distribution between workers from the european union and other regions of the world also more skilled and less skilled workers should remain balanced

the nature of precautionary wealth abstract this paper uses the panel study of income dynamics to provide some of the first direct evidence that wealth is systematically higher for consumers with predictably greater income uncertainty however the apparent pattern of precautionary wealth is not consistent with a standard parameterization of the life cucle model in which consumers are patient enough to begin saving for retirement early in life wealth is estimated to be far less sensitive to uncertainty than implied by that model instead our results suggest that over most of their working life time consumers behave in accordance with the buffer stock models of saving described in carroll 1992 1997 or deaton 1991 in which consumers hold wealth principally to insulate consumption against near term fluctuations in income

the impact of the 1962 repatriates from algeria on the french labor market this paper uses census data to examine the impact on the french labor market of the 900 000 people repatriated from algeria in 1962 repatriates settled in regions culturally and climatically simil

skilled immigration and the employment structures of u s firms we study the impact of skilled immigrants on the employment structures of us firms using matched employer employee data unlike most previous work we use the firm as the lens of analysis to account for greater heterogeneity and the fact that many skilled immigrant admissions are driven by firms themselves e g the h 1b visa ols and iv specifications show rising overall employment of skilled workers with increased skilled immigrant employment by the firm employment expansion is greater for young natives than for their older counterparts the departure rates for older workers relative to younger workers appear highest for those in stem occupations

the effect of immigration on unskilled native workers evidence from a natural experiment this study exploits the natural experiment provided by the start of the second intifada to measure the effect of immigration on the wage and employment of unskilled native workers it finds that immigration has no effect on the wage or employment of unskilled jewish workers the wage and employment of the least skilled israeli arab workers with zero to five years of schooling are adversely affected by immigration the slightly more skilled arab workers with six to 11 years of schooling in contrast are positively affected by immigration suggesting a complementarity effect with this group different explanations are proposed

winners and losers among a refugee hosting population abstractthe impact of a sudden mass influx of forced migrants on the hosting economy is understudied and not well understood using a household panel data set for the kagera region in tanzania we test the impact of the mass refugee presence on the welfare of the local population our identification strategy exploits variations in the timing of arrival as well as the spatial distribution of rwandese and burundi refugees we find a positive and aggregate effect but households are affected differently depending on their main initial occupation

how to measure labour market effects of immigration a review abstract this paper surveys available empirical evidence on labour market effects of immigration many different approaches have been used already to try to find out whether immigration hurts the labour market opportunities of natives no doubt new approaches will follow in the future as globalization will keep the migration issue on the agenda this literature review discusses the different approaches concentrating on both the methodology and the results at the end it tries to summarize available evidence

additional evidence for the career concern hypothesis with uncertainty of the retirement period the case of professional baseball players in japan this paper examines whether the career concern hypothesis which gibbons and murphy journal of political economy 100 1992 have presented holds in the labour market of professional baseball players in japan the hypothesis emphasizes that if workers are concerned about their career an optimal compensation contract has two incentives an explicit incentive from compensation for current performance and an implicit incentive from concern about their career and predicts that the explicit incentive should be strongest for workers close to retirement because the concern for their career is weakest for these workers incorporating the uncertainty of the retirement period evidences are found supporting the career concern hypothesis

evidence on the validity of cross sectional and longitudinal labor market data this article investigates error properties of survey reports of labor market variables we use the panel study of income dynamics psid validation study a two wave panel survey of workers employed by a large firm that shared its detailed payroll records individuals reports of annual earnings are fairly accurate errors are negatively related to true earnings reducing bias due to measurement error when earnings are used as an independent variable biases are moderately larger for changes in earnings earnings per hour are less reliably reported than annual earnings biases in estimating earnings functions are relatively small but those in labor supply functions may be important

moving back home insurance against labor market risk this paper demonstrates that the option to move in and out of the parental home is a valuable insurance channel against labor market risk which facilitates the pursuit of jobs with the potential for high earnings growth using monthly panel data i document an empirical relationship among coresidence individual labor market events and subsequent earnings growth i estimate the parameters of a dynamic game between youths and parents to show that the option to live at home can account for features of aggregate data for low skilled young workers small consumption responses to shocks high labor elasticities and low savings rates

the effect of mass influx on labor markets portuguese 1974 evidence revisited abstract this paper provides a reappraisal of the evidence from the influx that has been unique in the recent european history the flood of half a million returnees from mozambique and angola to portugal in the mid 1970s the objective of this paper is to study the impacts of a large supply shock on aggregate labor productivity wages and unemployment in contrast to the previous evidence the synthetic control analyses find that the influx had a significant adverse effect on labor market outcomes the results suggest that the portuguese labor market responded precisely the same way as the standard textbook model predicts an increase in the number of workers lowered average labor productivity and wages

the labor market consequences of refugee supply shocks summarythe continuing inflow of hundreds of thousands of refugees into many european countries has ignited much political controversy and raised questions that require a fuller understanding of the determinants and consequences of refugee supply shocks this paper revisits four historical refugee shocks to document their labour market impact specifically we examine the influx of marielitos into miami in 1980 the influx of french repatriates and algerian nationals into france at the end of the algerian independence war in 1962 the influx of jewish emigres into israel after the collapse of the soviet union in the early 1990s and the exodus of refugees from the former yugoslavia during the long series of balkan wars between 1991 and 2001 we use a common empirical approach derived from factor demand theory and publicly available data to measure the impact of these shocks despite the differences in the political forces that motivated the various flows and in economic conditions across receiving countries the evidence reveals a common thread that confirms key insights of the canonical model of a competitive labour market exogenous supply shocks adversely affect the labour market opportunities of competing natives in the receiving countries and often have a favorable impact on complementary workers in short refugee flows can have large distributional consequences

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

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

international labor economics i argue for increased reliance on non u s data and policy evaluations to understand basic labor market parameters and to predict the effects of changes in u s labor market policies foreign experiences generate exogenous shocks to labor costs that create unusual opportunities to measure impacts on labor demand foreign policies often provide more variation in the underlying parameters in systems that are often structured like their american counterparts foreign data sets are often larger and better suited to inferring behavior an empirical examination shows the effect of author s location data set and journal on the research s subsequent impact

inter industry wage differentials in eu countries what do cross country time varying data add to the picture this paper documents the existence and main patterns of inter industry wage differentials across a large number of industries for 8 eu countries belgium germany greece hungary ireland italy netherlands and spain at two points in time in general 1995 and 2002 and explores possible explanations for these patterns the analysis uses the european structure of earnings survey ses an internationally harmonised matched employer employee dataset to estimate inter industry wage differentials conditional on a rich set of employee employer and job characteristics after investigating the possibility that unobservable employee characteristics lie behind the conditional wage differentials a hypothesis which cannot be accepted the paper investigates the role of institutional industry structure and industry performance characteristics in explaining inter industry wage differentials the results suggest that inter industry wage differentials are consistent with rent sharing mechanisms and that rent sharing is more likely in industries with firm level collective agreements and with higher collective agreement coverage jel classification j31 j41 j51

job matching with finite horizon and risk aversion the consequences of introducing risk averse workers with a known finite retirement age into a simple job matching framework are explored the job matching model includes two jobs in the primary job workers and firms learn about the worker s productivity by observing his output over time in the secondary job productivity of any worker is known with certainty at the outset workers start off in the primary job but based on their observed performance may choose to switch to the secondary job the model is developed in two stages first the finite retirement age is introduced while the usual assumption of risk neutral workers is retained in this model it is shown that all workers who achieve at least a certain cumulative output record denoted r by a certain age denoted t will thereafter remain in the primary job until retirement those who do not achieve r by age t switch to the secondary job at or before age t and remain there second risk aversion is introduced along with finite retireme

insurance and opportunities a welfare analysis of labor market risk abstract using a model with constant relative risk aversion preferences endogenous labor supply and partial insurance against idiosyncratic wage risk this paper provides an analytical characterization of three welfare effects a the welfare effect of a rise in wage dispersion b the welfare gain from completing markets and c the welfare effect from eliminating risk the analysis reveals an important trade off for these welfare calculations on the one hand higher wage uncertainty increases the cost associated with missing insurance markets on the other hand greater wage dispersion presents opportunities to raise aggregate productivity by concentrating market work among more productive workers welfare effects can be expressed in terms of the underlying parameters defining preferences and wage risk or alternatively in terms of changes in observable second moments of the joint distribution over individual wages consumption and hours

income variance dynamics and heterogeneity recent theoretical work has shown the importance of measuring microeconomic uncertainty for models of both general and partial equilibrium under imperfect insurance in this paper the assumption of i i d income innovations used in previous empirical studies is removed and the focus of the analysis is placed on models for the conditional variance of income shocks which is related to the measure of risk emphasized by the theory we first discriminate amongst various models of earnings determination that separate income shocks into idiosyncratic transitory and permanent components we allow for education and time specific differences in the stochastic process for earnings and for measurement error the conditional variance of the income shocks is modelled as a parsimonious arch process with both observable and unobserved heterogeneity the empirical analysis is conducted on data drawn from the 1967 1992 panel study of income dynamics we find strong evidence of sizeable arch effects as well as evidence of unobserved heterogeneity in the variances

the impact of immigration why do studies reach such different results we classify the empirical literature on the wage impact of immigration into three groups where studies in the first two groups estimate different relative effects and studies in the third group estimate the total effect of immigration on wages we interpret the estimates obtained from the different approaches through the lens of the canonical model to demonstrate that they are not comparable we then relax two key assumptions in this literature allowing for inelastic and heterogeneous labor supply elasticities of natives and the downgrading of immigrants downgrading occurs when the position of immigrants in the labor market is systematically lower than the position of natives with the same observed education and experience levels downgrading means that immigrants receive lower returns to the same measured skills than natives when these skills are acquired in their country of origin we show that heterogeneous labor supply elasticities if ignored may complicate the interpretation of wage estimates and particularly the interpretation of relative wage effects moreover downgrading may lead to biased estimates in those approaches that estimate relative effects of immigration but not in approaches that estimate total effects we conclude that empirical models that estimate total effects not only answer important policy questions but are also more robust to alternative assumptions than models that estimate relative effects

the effect of migration on wages evidence from a natural experiment the objective of this paper is to employ the hurricane katrina evacuation into houston tx as a natural experiment to estimate the effect of large scale in migration on regional earnings given the characteristics of the evacuees their influx would have caused the supply of applicants for lower skilled jobs to increase proportionately more than for higher skilled jobs we utilize a differences in differences in differences methodology in which we compare differences in average earnings in the low skill non traded goods industries to the corresponding differences in the set of high skill industries in the houston and dallas fort worth msas before and after the katrina induced migration unlike previous studies we include a measure of the post storm increase in demand for local goods and services on the demand for labor we find evidence that the relative average payroll in the low skill non tradable goods industries in houston decreased by 7 when compared to the relative change for the same group of industries in dallas our findings also suggest that failure to account for demand side influences following the migration results in significant under estimation of wage effects due to the shift in labor supply

the dynamic impact of immigration on natives labor market outcomes evidence from israel abstract this paper studies the short and medium run impact of highly skilled immigrants from the former soviet union to israel on natives wages and employment if immigrants are relatively good substitutes for native workers the impact of immigration will be largest immediately upon the immigrants arrival and may become smaller as the labor market adjusts to the supply shock conversely if immigrants upon arrival are poor substitutes for natives the initial effect of immigration is small and increases over time as immigrants acquire local labor market skills and compete with native workers we empirically examine these alternative hypotheses using data from israel between 1989 and 1999 we find that wages of both men and women are negatively correlated with the fraction of immigrants with little local experience in a labor market segment a 10 percent increase in the share of immigrants lowers natives wages in the short run by 1 3 percent but this effect dissolves after 4 7 years this result is robust to a variety of different segmentations of the labor market to the inclusion of cohort effects and to different dynamic structures in the residual term of the wage equation on the other hand we do not find any effect of immigration on employment neither in the short nor in the medium run

a theory of dual labor markets with application to industrial policy discrimination and keynesian unemployment this paper develops a model of dual labor markets based on employers need to motivate workers in order to elicit effort from their workers employers may find it optimal to pay more than the going wage this changes fundamentally the character of labor markets the model is applied to a wide range of labor market phenomena it provides a coherent framework for understanding the claims of industrial policy advocates it also can provide the basis for a theory of occupational segregation and discrimination that will not be eroded by market forces finally the model provides the basis for a theory of involuntary unemployment

inter industry wage differentials revisited wage volatility and the option value of mobility analysis of data from the psid reveals that idiosyncratic wage volatility varies inversely with inter industry wage differentials and is positively correlated with both returns to industry tenure and rates of inter industry mobility an incomplete markets life cycle model in which inter industry mobility decisions and wage differentials are endogenously determined in equilibrium is then developed and shown to be capable of rationalizing these features of the data in the model the ability of worker to switch industries generates option value that is large enough to offset the standard risk premium that workers demand for exposure to excess wage volatility

mass migration to israel and natives employment transitions this study examines how mass migration from the former soviet union to israel affected natives probability of moving from employment to non employment and vice versa using 1989 99 data from the israeli labor force survey the authors find that the share of immigrants in labor market cells defined by occupation industry district of residence schooling and experience was generally positively associated with natives probability of moving from employment to non employment however when the analysis controls for the endogenous sorting of immigrants across cells this effect is substantially reduced for men and disappears or is even reversed for women the authors conclude that immigrants tended to cluster in labor market cells with high turnover rates and that immigration did not increase natives likelihood of exiting employment they also find no discernible effects of immigration on natives transitions between labor market cells or on the probability of their moving from non employment to employment

does unmeasured ability explain inter industry wage differentials this paper provides empirical assessments of the two leading explanations of measured inter industry wage differentials 1 true wage differentials exist across industries and 2 the measured differentials simply reflect unmeasured differences in workers productive abilities first we summarize the existing evidence on the unmeasured ability explanation second we construct a simple model which shows that if matching is important then endogenous job change decisions can create important self selection biases even in first differenced estimates of industry wage differentials third we analyze a sample that approximates the experiment of exogenous job loss we find that i the wage change experienced by a typical industry switcher closely resembles the difference in the relevant industry differentials estimated in a cross section and ii pre displacement industry affiliation plays an important role in post displacement wage determination

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

migration and imperfect labor markets theory and cross country evidence from denmark germany and the uk we investigate the labor market effects of immigration in denmark germany and the uk three countries which are characterized by considerable differences in labor market institutions and welfare states institutions such as collective bargaining minimum wages employment protection and unemployment benefits affect the way in which wages respond to labor supply shocks and hence the labor market effects of immigration we employ a wage setting approach which assumes that wages decline with the unemployment rate albeit imperfectly we find that the wage and employment effects of immigration depend on wage flexibility and the composition of the labor supply shock in germany immigration involves only moderate wage but large unemployment effects since immigrants are concentrated in labor market segments with low wage flexibility the reverse is true for the uk and denmark

the impact of young workers on the aggregate labor market an increase in the share of youth in the working age population of one state or region relative to the rest of the united states causes a sharp reduction in that state s relative unemployment rate and a modest increase in its labor force participation rate this is inconsistent with many theories of the labor market but can be easily explained by a model of frictional unemployment with on the job search the theory makes strong predictions regarding the behavior of wages which are shown to be consistent with the data the paper also reconciles its findings with an existing body of apparently contradictory empirical evidence

the craft of labormetrics using a wide array of examples from the literature and from original estimates the author examines the pitfalls that make good empirical research in labor economics at least as much craft as statistical technique among the subjects discussed are the appropriateness and cleanliness of data problems of extreme observations the validity of attempts to produce exogeneity using instrumental variables natural experiments and structural models and the treatment of selectivity and unobservable individual effects the author stresses the importance of testing empirical results to ensure that they make sense and of presenting them clearly and economically

the economics of immigration this literature review concerns the impact of immigration on the economy of the host country focusing on the experience of the united states the emphasis is on the period from the 1970s to the 1990s the author shows that research earlier in this period generally concluded that the economic effects of immigration were positive but that more recent research on later migrations have generally concluded that immigration may be having an adverse effect on the earnings of native unskilled workers and be placing an increased burden on welfare programs the importance of such economic analysis for the formulation of appropriate migration policies is stressed

the impact of 1970s repatriates from africa on the portuguese labor market this paper examines the labor market effect of the retornados who immigrated to portugal from angola and mozambique in the mid 1970s following portugal s loss of its african colonies the retornados increased the portuguese labor force by roughly 10 in just three years two analyses suggest contrasting conclusions first comparisons of portugal with spain and france indicate that any adverse effect of the retornados was quantitatively swamped by the europe wide downturn in labor market conditions in the 1970s second comparisons between districts within portugal indicate that the retornados may have had a strong adverse effect on portuguese wages suggesting that immigration may be considerably more harmful than previous case studies have concluded the authors however regard the results of the within portugal analysis as less reliable than those of the comparison across countries

which workers get insurance within the firm abstract industry level time series data suggest that low skilled workers get less insurance within the firm than high skilled workers in particular wages respond relatively more to productivity shocks in low skilled industries than high skilled industries our theory is that low skilled workers get relatively less insurance from their firms because they have relatively lower displacement costs under limited commitment lower displacement costs make the workers outside options more attractive and hence decrease the amount of risk sharing sustainable within the firm evidence on average displacement costs by industry support the theory s predictions

the labour market impact of immigration in the first part of this paper we present a stylized model of the labour market impact of immigra tion we then discuss mechanisms through which an economy can adjust to immigration changes in factor prices output mix and production technology in the second part we explain the problems of empirically estimating how immigration affects labour market outcomes of the resident population and review some strategies to address these we then summarize some recent empirical studies for the uk and other countries we conclude with an outlook on what we believe are important avenues for future research

job matching and occupational choice this paper presents a model of job matching the generalizes the existing literature by allowing for different jobs types or occupations such differences affect the value of job specific experience inducing a career profile where certain types are sampled before others more specifically the analysis shows that it is optimal for the young and inexperienced to gravitate toward jobs exhibiting a certain kind of risk then after deriving the equilibrium job turnover rate for an economy in which people do not switch occupations panel data are used to estimate its underlying parameters the hypothesis that people do not switch occupations is rejected against the alternative that they do thus providing empirical support for the theoretical extension undertaken here

rising occupational and industry mobility in the united states 1968 97 we document and analyze the high level and the substantial increase in worker mobility in the united states over the 1968 97 period at various levels of occupational and industry aggregation this is important in light of the recent findings that human capital of workers is largely occupation or industry specific to control for measurement error in occupation and industry coding we develop a method that utilizes the psid retrospective occupation industry supplemental data files we emphasize the importance of our findings for understanding a number of issues such as the changes in wage inequality aggregate productivity job stability and life cycle earnings profiles
