equilibrium search models and the transition from school to work this paper applies the burdett mortensen 1998 equilibrium search model to study the school to work transitions of u s high school graduates we consider the case of discrete firm heterogeneity and provide a computational method to obtain the mle our results show that unemployed blacks receive fewer offers than whites and employed blacks are more likely to lose their jobs importantly employed blacks and whites receive job offers at the same rate assigning the whites search parameters to the blacks and re solving reveals that 75 percent of the observed wage differential is explained by the job destruction rate differences

gender wage gaps reconsidered a structural approach using matched employer employee data in this paper we study the extent to which wage differentials between men and women can be explained by differences in productivity disparities in friction patterns segregation and wage discrimination for this purpose we propose an equilibrium search model that features rent splitting on the job search and two sided heterogeneity in productivity the model is estimated using german matched employer employee data overall the results reveal that female workers are less productive and more mobile than males in addition female workers have on average slightly lower bargaining power than their male counterparts

cyclicality and the labor market for economists the 1987 academic market was strong whereas the 1997 market was weak a multimarket theory of optimal search suggests that job seekers will respond to a weakening market by changing their search strategies at the extensive margin which markets to enter and the intensive margin how many applications to submit per market employers respond to the weakening market by raising their hiring standards high quality applicants will obtain an increased share of academic interviews in weak markets while applicants from weaker schools will increasingly secure interviews outside of the academic market empirical results show that in the bust market graduates of elite schools shifted their search strategies to include weaker academic institutions while graduates of lower ranked schools shifted their applications away from academia and toward the business sector in bust conditions academic institu tions increasingly concentrate their interviews on elite school graduates women and u s residents

selecting successful students undergraduate grades as an admission criterion abstractin europe s reformed education system universities may be forced by law to consider undergraduate grade point average ugpa as the primary admission criterion in the selection of graduate students in this article we investigate whether ugpa predicts graduate student performance in order to discuss its usefulness as an admission criterion in our theoretical framework we show that undergraduate students may choose slower study progress in favour of receiving higher grades and conclude that ugpa is a relatively good weak predictor for graduate grade point average study progress having data from a cohort of students whose selection was in clear conflict with the legal requirement we empirically confirm our theoretical predictions by exploiting a unique opportunity for assessing educational policies discussion of our findings leads to some important conclusions concerning the bologna reforms and the lawmakers idea of giving some independence to universities but not too much of it

job search and hyperbolic discounting structural estimation and policy evaluation this paper estimates the structural parameters of a job search model with hyperbolic discounting and endogenous search effort it estimates quantitatively the degree of hyperbolic discounting and assesses its implications for the impact of various policy interventions aimed at reducing unemployment the model is estimated using data on unemployment spells and accepted wages from the national longitudinal survey of youth nlsy the likelihood function explicitly incorporates all the restrictions implied by the optimal dynamic programming solution to the model both observed and unobserved heterogeneity are accounted for the results point to a substantial degree of hyperbolic discounting especially for low and medium wage workers the structural estimates are also used to evaluate alternative policy interventions for the unemployed estimates based on a model with exponential discounting may lead to biased inference on the economic impact of policies jel c6 c73 d90 j64 j68

the effects of changes of the job offer arrival rate on the duration of unemployment generally it is acknowledged that changing the job offer arrival rate has two opposite effects on unemployment duration for a basic job search model sufficient conditions on the wage offer distribution have been derived ensuring that one of the effects dominates however these are not satisfied for the popular families of wage offer distributions here i show that the conditions can be weakened at virtually no cost the set of distributions satisfying the new conditions is considerably larger than the set previously established in particular it includes all wage offer distribution families that are popular in structural empirical research

estimating a market equilibrium search model from panel data on individuals from albrecht and axell 1984 and is based on workers who are homogeneous in terms of market productivity and heterogeneous in terms of nonmarket productivity and on firms which are heterogeneous in terms of productive efficiency the equilibrium model is contrasted in terms of its fit to the data with an unrestricted version of the model which is based on a mixture of negative binomial distributions the equilibrium model fails to conform to the data in exactly the dimension of its major focus namely it implies that measurement error accounts for almost all of the dispersion in observed wages the equilibrium model also does not do well in fitting the unemployment duration distribution compared to the unrestricted model the problem is that the duration distribution itself does not support the existence of significant heterogeneity as evidenced by the estimates of the unrestricted model the paper also illustrates the use of such models for policy analysis by simulating the welfare effects of a minimum wage

estimating a simultaneous search model the primary goal of this article is to specify and estimate a structural simultaneous search model and then determine the empirical importance of simultaneous search the results indicate that new labor force entrants search simultaneously a secondary goal is to identify and estimate job offer arrival rates and wage offer rejection probabilities separately the results indicate that a significant portion of unemployment spells are caused by slow arrival rates but policies intended to speed arrival rates would increase the average length of unemployment spells

wage differentials employer size and unemployment the unique equilibrium solution to a game in which a continuum of individual employers choose permanent wage offers and a continuum of workers search by sequentially sampling from the set of offers is characterized wage dispersion is a robust outcome provided that workers search while employed as well as when unemployed the unique nondegenerate equilibrium distribution of wage offers is constructed for three cases 1 identical workers and employers 2 identical employers and an atomless distribution of worker supply prices and 3 identical workers and an atomless distribution of job productivities copyright 1998 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

on the job search and the wage distribution the article structually estimates an on the job search model of job separations given each employer pays observably equivalent workers the same but wages are dispersed across employers an employer s separation flow is the sum of an exogenous outflow unrelated to the wage and a job to job flow that decreases with the employer s wage using data from the danish integrated database for labour market research the empirical results imply as predicted by theory that search effort declines with the wage furthermore the estimates explain the employment effect defined as the horizontal difference between the distribution of wages earned and the wage offer distribution

job search hours restrictions and desired hours of work a structural empirical job search model is presented that incorporates the labor supply decision of individuals the arrival of a job offer is modeled as a random draw from a wage hours offer distribution subjective information is used on desired working hours to identify optimal hours from offered hours policy simulations are performed to address several policy questions does a decrease in unemployment benefits lead to the acceptance of jobs with less preferred working hours how does a decrease in the length of the standard working week affect the job acceptance behavior of the unemployed

cohabitation marriage and divorce in a model of match quality the objective of this research is to further our understanding of how and why individuals enter and leave coresidential relationships we develop and estimate an economic model of nonmarital cohabitation marriage and divorce that is consistent with current data on the formation and dissolution of relationships jovanovic s journal of political economy 87 1979 972 90 theoretical matching model is extended to help explain household formation and dissolution behavior implications of the model reveal what factors influence the decision to start a relationship what form this relationship will take and the relative stability of the various types of unions the structural parameters of the model are estimated using longitudinal data from a sample of female high school seniors from the united states new numerical methods are developed to reduce computational costs associated with estimation the empirical results have interesting interpretations given the structural model they show that a significant cause of cohabitation is the need to learn about potential partners and to hedge against future bad shocks the estimated parameters are used to conduct several comparative dynamic experiments for example we show that policy experiments changing the cost of divorce have little effect on relationship choices

placement service and offer arrival rates abstract determinants of job referrals by the austrian employment exchange are analyzed concentrating on three issues the validity of the poisson assumption allocation strategies of scarce vacancies and the stationarity of offer arrival rates over time

does the public employment service affect search effort and outcomes in this paper we examine the disincentive effects of the public employment service on the search effort of unemployed workers and on their exit rate from unemployment for that purpose we specify a structural search model with fixed and variable costs of search in which unemployed workers select their optimal search intensity given the exogenous arrival rate of job contacts coming from the public employment agency because the theoretical effect of an increase in this exogenous job contact arrival rate on the structural exit rate from unemployment is ambiguous we estimate this model using individual unemployment duration data our results show that the exit rate from unemployment increases with the arrival rate of job contacts obtained by the public employment service especially for low educated and low skilled workers they also show that the search effort is more costly for low educated women and low skilled adult unemployed workers this last result suggests that a public employment agency that matches searchers and employers is beneficial in the sense that it saves searchers in terms of search costs they would otherwise bear

matching search and bargaining abstract first the paper incorporates search for alternative opportunities into a model of strategic bargaining second this search and bargaining model is embedded in a market matching model the solutions are presented in a manner that clarifies the role of the search abilities and the details of the bargaining procedure in the determination of the outcomes the predictions of the model are contrasted with the related literature the main accomplishment is the attainment of a manageable model which is still rich enough to grasp important differences between environments which are not captured by the standard matching models

frictional wage dispersion in search models a quantitative assessment we propose a new measure of frictional wage dispersion the mean min wage ratio for a large class of search models we show that this measure is independent of the wage offer distribution but depends on statistics of labor market turnover and on preferences under plausible preference parameterizations observed magnitudes for worker flows imply that in the basic search model and in most of its extensions frictional wage dispersion is very small notable exceptions are some of the most recent models of on the job search our new measure allows us to rationalize the diverse empirical findings in the large literature estimating structural search models

optimal carbon taxes for emissions targets in the electricity sector the most dangerous effects of anthropogenic climate change can be mitigated by using emissions taxes or other regulatory interventions to reduce greenhouse gas ghg emissions this paper takes a regulatory viewpoint and describes the weighted sum bisection method to determine the lowest emission tax rate that can reduce the anticipated emissions of the power sector below a prescribed regulatorily defined target this bilevel method accounts for a variety of operating conditions via stochastic programming and remains computationally tractable for realistically large planning test systems even when binary commitment decisions and multiperiod constraints on conventional generators are considered case studies on a modified iso new england test system demonstrate that this method reliably finds the minimum tax rate that meets emissions targets in addition it investigates the relationship between system investments and the tax setting process introducing ghg emissions taxes increases the value proposition for investment in new cleaner generation transmission and energy efficiency conversely investing in these technologies reduces the tax rate required to reach a given emissions target

the determinants of black white differences in early employment careers search layoffs quits and endogenous wage growth this paper studies the transition from school to full time employment and subsequent labor mobility during the first five postschooling years for several recent cohorts of black and white male terminal high school graduates using unique data from the 1979 youth cohort of the national longitudinal surveys of labor market experience a constrained optimization model of labor force dynamics is implemented empirically integrating features of models previously described in the literature the estimates of the model provide quantitative evidence on underlying structural differences in labor market constraints faced by blacks and whites for example while blacks have overall a substantially smaller wage return to work experience and face a less disperse wage offer distribution blacks face a higher probability of receiving job offers

an empirical examination of the sources of changes over time in the job finding rate using reservation wages and rejected wage offers we consider a structural dynamic job search model where nonstationarity originates from the change over time in the benefit level the job offer arrival rate and the wage offer distribution the model is estimated on the french sample of the echp taking advantage of direct observation of reservation wages rejected job offers and associated rejected wages we find that the offered wages deteriorate rapidly 13 8 over six months 19 2 over one year and 30 over two years and that changes in the wage offer distribution are the unique source of negative duration dependence in the hazard

search and nonwage job characteristics this paper quantifies the importance of nonwage job characteristics to workers by estimating a structural on the job search model the model generalizes the standard search framework by allowing workers to search for jobs based on both wages and job specific nonwage utility flows within the structure of the search model data on accepted wages and wage changes at job transitions identify the importance of nonwage utility through revealed preference the estimates reveal that utility from nonwage job characteristics plays an important role in determining job mobility the value of jobs to workers and the gains from job search

unemployment insurance eligibility and the scholl to work transition in canada and the united states to study how the design of unemployment insurance ui affects people leaving school to find jobs a model of job search in the presence of ui is developed and estimated for the united states and canada the level of ui benefits depends on previous earnings which creates opposing incentives for unemployed people not receiving benefits which of these opposing incentives dominates the other is found to differ across demographic groups within each country changes in ui policy therefore can have very different effects on different individuals the major differences found in the transition from school to work in canada and the united states are a lower rate of job offer arrivals and a lower rate of offer rejections in canada within each country offer arrival rates differ across individuals much more than offer rejection rates

job search search intensity and labor market transitions an empirical analysis this article proposes an empirical structural job search model with endogenously determined search intensity the model describes both the behaviour of unemployed job seekers and on the job search it draws on data on various indicators for the intensity of search to examine the effect of the intensity of search on labour market transitions the estimation results provide insight into the effectiveness of search the impact of the benefit level on the search intensity of unemployed job seekers is quantified the estimation results are used to gain insight into the discouraged worker effect

search behaviour transitions to non participation and the duration of unemployment using longitudinal micro data on unemployed individuals for 1983 85 a structural job search model is estimated the model allows for transitions from unemployment to nonparticipation an extended version of the model deals with the influence of on the job search and prospective wage increases on search behavior of the unemployed the empirical results show that the probability of accepting a job offer is almost one for most unemployed individuals a large portion of unemployment spells ends in a transition out of the labor force the effects of changes in benefits on duration appear to be extremely small copyright 1990 by royal economic society

individual wealth reservation wages and transitions into employment we investigate the relationship between financial wealth reservation wages and labor market transitions wealth is assumed to affect the level of the reservation wage and the employment probability we test for the validity of this assumption by estimating a simultaneous equations model of reservation wages labor market transitions and wealth the data used for the analysis relate to a sample of unemployed job searchers we use subjective information on the reservation wage wealth is found to have a significantly positive impact on the reservation wage the overall impact of wealth on the employment probability is negative though small

empirical matching functions searchers vacancies and un biased elasticities this paper shows that conventional empirical estimates of matching functions are systematically biased because unobservable and endogenous search behaviour such as on the job search by workers or the use of different search channels by firms is neglected i propose an approach for recovering unbiased elasticities under different scenarios of competition for workers and jobs without the need for constructing proxies for unobserved stocks of searchers and vacancies using german administrative data i estimate the biases affecting conventional studies and derive bias corrected estimates of the matching elasticities under different scenarios

strategic bargaining models and interpretation of strike data attrition screening and signalling models of strategic bargaining are characterized in terms of their predictions about the incidence mean duration and settlement rates of strikes and the terms of wage settlements these predictions are compared with the general features observed in empirical studies of strikes in canada and the united states conclusions are drawn about the types of models capable of generating these features and about the conformity of the models to the evidence methods are described for computing the numerical examples used to illustrate the models

search costs and efficiency do unemployed workers search enough many labor market policies affect the marginal benefits and costs of job search the impact and desirability of such policies depend on the distribution of search costs in this paper we provide an equilibrium framework for identifying the distribution of search costs and we apply it to the dutch labor market in our model the wage distribution job search intensities and firm entry are simultaneously determined in market equilibrium given the distribution of search intensities which we directly observe we calibrate the search cost distribution and the flow value of non market time these values are then used to derive the socially optimal firm entry rates and distribution of job search intensities from a social point of view some unemployed workers search too little due to a hold up problem while other unemployed workers search too much due to coordination frictions and rent seeking behavior our results indicate that jointly increasing unemployment benefits and the sanctions for unemployed workers who do not search at all can be welfare improving

job search and academic achievement abstract the paper develops a structural model for the labor market behavior of students entering the labor market we explicitly model the trade off between devoting effort to studying and to job search furthermore we allow for on the job search the model is estimated using a unique data set of individuals who completed undergraduate education in the netherlands between 1995 and 2001 our estimation results show that labor market returns of high grades are low wage increases between jobs are explained by labor market friction rather than returns of early work experience our results indicate that a 1 percentage point decrease in the unemployment rate increases wage offers on average by 3 percent but that the amount of job search effort is not very sensitive to business cycle fluctuations policy simulations show that study effort and hence academic achievement are much more sensitive to financial incentives than job search effort and labor market outcomes

duration to first job and the return to schooling estimates from a search matching model this paper investigates the properties of the joint distribution of the duration to the first post schooling full time job and of the accepted wage for that job within a search matchingbargaining theoretic model the model provides an interpretation of the observations on duration to first job and accepted wages that differentiates between behavioural influences and market fundamentals in determining the accepted wage schooling relationship the return to schooling is appropriately measured by differences in the wage offer distribution which depends only on market fundamentals we use data from the 1979 youth cohort of the national longitudinal surveys of labor market experience to follow several school leaving cohorts of young males a model which allows for five types of heterogeneous workers within schooling race groups fits the duration and wage data well for all such groups offer probabilities for all groups are estimated to be close to one mean offered wages are about 1000 less than mean accepted wages and the internal annual rate of return for attending college relative to graduating from high school is 32 for blacks and 17 for whites this paper investigates the properties of the joint distribution of the duration to the first post schooling full time job and of the accepted wage for that job within a search matching bargaining model it is a well established empirical regularity that hazard rates are decreasing with the duration of search unemployment it is also true for the data we use that the sample mean of the accepted wage associated with the first job is not increasing with duration these findings hold for both black and white male youth at all levels of schooling conditional on schooling however the time between leaving school and working at the first full time job is longer for blacks and their accepted mean wage is lower conditional on race the time between leaving school and working at the first full time job is shorter for those with higher levels of schooling and their accepted mean wage is higher interestingly blacks display a similar pattern of duration and accepted wages to whites who are one level of schooling below e g black high school graduates and white high school dropouts

an empirical equilibrium search model of the labor market in structural empirical models of labor market search the distribution of wage offers is usually assumed to be exogenous however because in setting their wages profit maximizing firms should consider the reservation wages of job seekers the wage offer distribution is essentially endogenous we investigate whether a proposed equilibrium search model in which the wage offer distribution is endogenous is able to describe observed labor market histories we find that the distributions of job and unemployment spells are consistent with the data and that the qualitative predictions of the model for the wages set by employers are confirmed by wage regressions the model is estimated using panel data on unemployed and employed individuals we distinguish between separate segments of the labor market and we show that productivity heterogeneity is important to obtain an acceptable fit to the data the results are used to estimate the degree of monopsony power of firms further the effects of changes in the mandatory minimum wage are examined

reference dependent job search evidence from hungary we propose a model of job search with reference dependent preferences with loss aversion relative to recent income the reference point in this model newly unemployed individuals search hard since consumption is below their reference point over time though they get used to lower income and thus reduce their search effort in anticipation of a benefit cut their search effort rises again then declines once they get accustomed to the lower postcut benefit level the model fits the typical pattern of exit from unemployment even with no unobserved heterogeneity to distinguish between this and other models we use a unique reform in the unemployment insurance ui benefit path in 2005 hungary switched from a single step ui system to a two step system with overall generosity unchanged the system generated increased hazard rates in anticipation of and especially following benefit cuts in ways the standard model has a hard time explaining we estimate a model with optimal consumption endogenous search effort and unobserved heterogeneity the reference dependent model fits the hazard rates substantially better than plausible versions of the standard model including habit formation our estimates indicate a slow adjusting reference point and substantial impatience likely reflecting present bias jel codes d03 j64 j65

the regional economic impact of an airport the case of amsterdam schiphol the completion of the so called third package in the liberalization of european aviation has changed the environment in which airports operate considerably the continued growth of air traffic has led to a public debate in many western countries about the expansion of airport capacity in the light of the externalities emanating from these traffic nodes in this paper we try to measure the economic impact of amsterdam schiphol airport on the greater amsterdam region by means of a social accounting matrix of this region the paper tries to avoid some of the pitfalls of earlier studies by using a counterfactual approach in measuring the economic impact we are able to distinguish employment created in sub regions of the greater amsterdam region and the education and qualification levels associated with this employment our results indicate that the total multiplier of direct employment on amsterdam schiphol airport is approximately 2 one job on the airport leads to approximately one job in indirect and

the evolution of mass tourism destinations new approaches beyond deterministic models in benidorm spain although deterministic models of the evolution of mass tourism coastal resorts predict an almost inevitable decline over time theoretical frameworks of the evolution and restructuring policies of mature destinations should be revised to reflect the complex and dynamic way in which these destinations evolve and interact with the tourism market and global socio economic environment the present study examines benidorm because its urban and tourism model and large scale tourism supply and demand make it one of the most unique destinations on the mediterranean coast the investigation reveals the need to adopt theories and models that are not purely deterministic the dialectic interplay between external factors and the internal factors inherent in this destination simultaneously reveals a complex and diverse stage of maturity and the ability of destinations to create their own future

search for nonwage job characteristics a test of the reservation wage hypothesis previous structural models of job search behavior have been based upon the reservation wage property this article provides estimates of a more general search model that nests models with the reservation wage property the estimates lead to rejection of the reservation wage property the model includes hours of work in the utility function but other nonwage job characteristics can be included as well an experiment based on the estimated parameters indicates that a significant proportion of job offers would be mistakenly predicted to be accepted or rejected under the restrictions implied by the reservation wage property

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
