do labor market policies have displacement effects evidence from a clustered randomized experiment this article reports the results from a randomized experiment designed to evaluate the direct and indirect displacement impacts of job placement assistance on the labor market outcomes of young educated job seekers in france we use a two step design in the first step the proportions of job seekers to be assigned to treatment 0 25 50 75 or 100 were randomly drawn for each of the 235 labor markets e g cities participating in the experiment then in each labor market eligible job seekers were randomly assigned to the treatment following this proportion after eight months eligible unemployed youths who were assigned to the program were significantly more likely to have found a stable job than those who were not but these gains are transitory and they appear to have come partly at the expense of eligible workers who did not benefit from the program particularly in labor markets where they compete mainly with other educated workers and in weak labor markets overall the program seems to have had very little net benefits

search unemployment and the production of jobs the authors investigate the performance of the economy when search is required to find employment and when the duration of unemployment varies across sectors they assume that in one sector factor markets are frictionless while in the other se ctor idle factors of production must actively search each other out i n order to produce they focus on how well the economy allocates work ers across sectors and the conditions under which the factor mix with in a sector is correct the authors demonstrate that in equilibrium t he search sector is too small and its factor intensity is too asymmet ric copyright 1987 by royal economic society

the long run effects of unemployment monitoring and work search programs experimental evidence from the united kingdom this article examines the long run effects of the restart unemployment program in the united kingdom the program aimed at the long term unemployed involved a combination of tighter monitoring of benefit eligibility rules and increased job search assistance we compare the employment behavior of a treatment group who participated in the scheme with that of a randomly chosen control group for whom participation was delayed while there is little evidence of a long term benefit for women the unemployment rate among males in the treatment group was six percentage points lower than that of the control group 5 years after the initial experiment

nonstationarity in job search theory generally structural job search models are taken to be stationary in this paper models are examined in which every exogenous variable can cause nonstationarity for instance because its value is dependent on unemployment duration a general differential equation that describes the evolution of the reservation wage over time is derived as an empirical illustration a nonstationary structural model is estimated that focuses on the consequences of a downward shift in the level of benefits it appears that the elasticity of duration with respect to the level of benefits after the shift is much larger than the elasticity with respect to the level before the shift this paper examines the movement of a job seeking individual s reservation wage over time in a general nonstationary job search model also results concerning comparative dynamics of the reservation wage and the distribution of the duration of unemployment are derived as an empirical illustration a nonstationary structural model is estimated the nonstationarity originates from the decrease in the level of benefits when unemployment duration equals two years from the results some detailed policy recommendations can be deduced as one is able to distinguish the effect of a change in the level of benefits in the first two years of unemployment from the effect of a change in the level after that period recently the use of job search models for the analysis of unemployment duration has become widespread the reduced form approach in empirical studies see e g lancaster 1979 in which only the hazard of the duration distribution is estimated is gradually being replaced by a more structural approach the latter way of modelling is characterized by the explicit use in empirical analysis of the reservation wage equation as stated by the theory e g yoon 1981 lancaster and chesher 1983 lynch 1983 narendranathan and nickell 1985 and van den berg 1988 use the complete theoretical framework of job search theory to make inferences about search behaviour however the structural models used in these studies are stationary this implies that variables like unemployment benefits or the rate of arrival of job offers are assumed to be constant over the spell of unemployment which is often at variance with reality what is more various reduced form empirical studies indicate a significant durationdependence of the re employment probability which is generally interpreted as evidence in favour of the presence of nonstationarity see e g blau and robins 1986 kooreman and ridder 1983 lancaster 1979 and narendranathan nickell and stern 1985 consequently there is a need to model reservation wage movements over time based on a nonstationary theoretical framework

choosy search and the mismatch of talents this article proposes a multi sector matching model where workers have symmetric sector specific skills and the search market is segmented by sector workers choose the range of markets they are willing to participate in i identify a composition externality workers do not take into account the impact of their choice on sector specific mean productivity among the pools of job seekers consequently workers prospect too many market segments and there is room for public policy even when the so called hosios condition holds

micro data heterogeneity and the evaluation of public policy nobel lecture this paper summarizes the contributions of microeconometrics to economic knowledge four main themes are developed 1 microeconometricians developed new tools to respond to econometric problems raised by the analysis of the new sources of micro data produced after the second world war 2 microeconometrics improved on aggregate time series methods by building models that linked economic models for individuals to data on individual behavior 3 an important empirical regularity detected by the field is the diversity and heterogeneity of behavior this heterogeneity has profound consequences for economic theory and for econometric practice 4 microeconometrics has contributed substantially to the scientific evaluation of public policy

seigniorage operating rules and the high inflation trap there may be both a high and a low inflation equilibrium when the government finances the deficit through seigniorage under rational expectations the high inflation equilibrium is stable and the low inflation equilibrium unstable under adaptive expectations or lagged adjustment of money balances with rational expectations the low inflation equilibrium may be stable adding bond financing dual equilibria remain if the government fixes the real interest rate but a unique equilibrium is attained when the government sets a nominal anchor for the economy the existence of dual equilibria is thus a result of the government s operating rules

unravelling of dynamic sorting we consider a two sided finite horizon search and matching model with heterogeneous types and complementarity between types the quality of the pool of potential partners deteriorates as agents who have found mutually agreeable matches exit the market when search is costless and all agents participate in each matching round the market performs a sorting function in that high types of agents have multiple chances to match with their peers however this sorting function is lost if agents incur an arbitrarily small cost in order to participate in each round with a sufficiently rich type space the market unravels as almost all agents rush to participate in the first round and match and exit with anyone they meet copyright 2005 wiley blackwell

international organizations and the political economy of reforms abstract we develop a simple dynamic model of policy reform that captures some of the determinants that underlie the differences between the reform paths taken by a number of countries since the early 1990s the model focuses on the interaction between domestic institutions and international organizations that promote reform on the one hand and the political incentives for reversing reforms on the other at equilibrium there are three types of reform paths a country can undergo a full scale lasting reform can carry out a partial but lasting reform or can go through cycles of reforms and costly counter reforms domestic institutions along with the incentives provided by international organizations determine the equilibrium path a politically myopic international organization may induce cycles of reforms and costly counter reforms thereby reducing the country s well being an international organization that only provides funds to promote reforms may have a less beneficial effect than one that assists the country with fresh funds to defend reforms when there is a risk of reversal international funds that promote reforms can also influence domestic institutions for example due to the intervention of an international organization countries could have incentives to dismantle institutions that build up reversal cost and or do not fully build their fiscal capacity

accounting for the timing of first marriage among first marriages in the united states grooms are on average 1 7 years older than their brides traditionally this fact is explained by sex differences in income we use a general equilibrium overlapping generations search model economy to show instead that sex differences in fecundity are essential to account for the age gap at first marriage whereas sex differences in income play a secondary role our model economy also accounts for other facts on the timing of first marriages that the literature has overlooked

matching workers and jobs cyclical fluctuations in match quality using national longitudinal survey of youth data on tenure and wages this article analyzes the extent to which the level of job mismatching varies over the business cycle and how it is dealt with by the labor market i find significant cyclical variation in job match quality and an internalization of the variation by the labor market through wages mismatching occurs more during recessions but is primarily captured in starting wages the evidence suggests the cyclical phenomenon is one of general mismatching rather than an increased number of stopgap jobs during recessions

the family as an incomplete annuities market families can self insure against uncertain dates of death through implicit or explicit agreements with respect to consumption and interfamily transfers interfamily transfers need have nothing to do with altruistic feelings they may simply reflect risk sharing behavior of completely selfish family members although family annuity markets are incomplete even small families can substitute by more than 70 percent for perfect market annuities given adverse selection and transaction costs family risk pooling may be preferred to public market annuities in the absence of public annuities these risk sharing arrangements provide powerful incentives for marriage and family formation

schooling search and spouse selection testing economic theories of marriage and household behavior the implications of the economic theories of marriage and of household fertility behavior are tested in a framework in which educational investment marital search and marital matches are responsive to marriage market conditions and the personal traits of individual agents some of which are unobserved by the econometrician implications are also derived and tested for the effects of longevity attractiveness preferences and labor and marriage market conditions on schooling marriage age and spouse choice the empirical results indicate that inattention to heterogeneity and martial selection leads to a false rejection of the economic theory of marriage but to a false acceptance of the value of time fertility hypothesis

fiscal conservatism as a response to the debt crisis abstract in this paper we develop a model in which social conflict and adjustment costs induce delayed inflation stabilization we show that the longer this delay is the less demanding are the conditions that some groups will accept in order to stabilize in the context of the latin american debt crisis our model gives a rationale for the time lag between the outset of the crisis and the implementation of reform programs as well as for the strongly conservative nature of those that are currently being implemented

why are stabilizations delayed when a stabilization has significant distributional implications e g tax increases to eliminate a large budget deficit socioeconomic groups may attempt to shift the burden of stabilization onto other groups the process leading to stabilization becomes a war of attrition each group attempting to wait the others out and stabilization occurring only when one group concedes and bears a disproportionate share of the burden the authors solve for the expected time of stabilization in a model of rational delay and relate it to several political and economic variables they motivate this approach and its results by comparison to historical and current episodes copyright 1991 by american economic association

holding on ethnic divisions political institutions and the duration of economic declines abstract we analyze the duration of large economic declines and provide a theory of delayed recovery we show theoretically that uncertain post recovery incomes lead to a commitment problem which limits the possibility of cooperation in ethnically heterogeneous countries strong constraints on the executive solve this problem by reducing the uncertainty associated with cooperative behavior we test the model using standard data on linguistic heterogeneity and detailed data on ethnic power configurations our findings support the central theoretical prediction countries with more constrained political executives experience shorter economic declines the effect is large in ethnically heterogeneous countries but virtually non existent in homogeneous societies our main results are robust to a variety of perturbations regarding the estimation method the estimation sample measures of heterogeneity and measures of institutions

on the emergence of toyboys the timing of marriage with aging and uncertain careers we explore how gender bias in career opportunities affects matching in a marriage market with search frictions and where an individual s fitness decays with age we document a being left on the shelf effect where young singles who find the marriage market rapidly thins with age rush into early partnership singles with stronger career opportunities however have a greater option value to defer marriage more equal career opportunities for women captured by greater schooling and better occupations potentially explain the recent emergence of toyboy unions in which the woman is at least 5 years older than her partner 2011 by the economics department of the university of pennsylvania and the osaka university institute of social and economic research association

does city structure affect job search and welfare we develop a model in which workers search efficiency is negatively affected by access to jobs workers location in a city is endogenous and reflects a trade off between commuting costs and the surplus associated with search different configurations emerge in equilibrium notably the unemployed workers may reside far away segregated city or close to jobs integrated city we prove that there exists a unique and stable market equilibrium in which both land and labor markets are solved for simultaneously we find that despite inefficient search in the segregated city equilibrium the welfare difference between the two equilibria is not so large due to differences in commuting costs we also show how a social planner can manipulate wages by subsidizing taxing the transport costs and can accordingly restore the efficiency

desperation or desire the role of risk aversion in marriage i introduction attitudes toward risk are an important determinant of a vast array of decisions such decisions include ones with a big impact on life the choice of education the choice of career investment decisions and even when and if to get married or divorced most empirical studies of behavior implicitly assume risk preferences are identical across households such a research strategy undoubtedly results in appreciably different predictions of behavior than would occur if risk preferences are permitted to vary while an increasing number of surveys are asking respondents questions that allow for construction of a measure of interpersonal variation in risk that is based on economic theory there is still a paucity of empirical studies that explicitly investigate the impact of risk preferences on behavior 1 i use information on risk preferences from the national longitudinal survey of youth 1979 nlsy79 to predict how interpersonal variation in these preferences affects the time to marriage decision because of the uncertainty inherent in searching for a partner and the uncertainty of the future quality and state of the marriage itself risk attitudes likely directly impact the timing of marriage risk preference variables are constructed from a series of hypothetical gambles over lifetime income that were offered to respondents in the nlsy79 i examine how the risk preference variables affect the hazard rate into marriage and find that the more risk averse marry sooner l also exploit sibling data from the nlsy79 to examine the robustness of the empirical results by controlling for unobserved family effects that might be correlated with risk attitudes and find qualitatively similar results in addition i find that risk preferences affect the timing of marriage differentially for the sexes with a larger and more statistically significant effect of risk preferences on the hazard rate into marriage for men one possible explanation for this finding is that women value risk aversion as a desirable characteristic in a spouse to explore this possibility i analyze spouse characteristics by the risk aversion of the respondent i find that spouse quality in terms of education and other measurable traits is generally lower for more risk averse men than for more risk loving men this finding is in accordance with a prediction of a search model the reservation price is decreasing in risk aversion spouse quality of more risk averse women is usually but not always lower than for more risk loving women suggesting that the effect of a woman s own risk aversion on time to marriage may be more complex than suggested by a search model overall the results suggest that risk preferences have some causal influence on the timing of marriage whether it be from a supply side standpoint such as in the case of a basic search model or from a demand side standpoint where risk aversion is a desirable trait this article contributes to a sparse literature that employs empirical measures of risk aversion many of these studies ask how demographic characteristics affect risk attitudes 2 a few ask how these measures of risk aversion affect behaviors like the propensity to smoke or invest in risky assets 3 these studies are however cross sectional and do not employ survival analysis as does this article to my knowledge only two existing studies light and ahn 2008 schmidt 2008 employ an empirical measure of risk aversion to investigate the relationship between risk preferences and the marriage market schmidt focuses on fertility but also considers marital timing of employed women and light and abn focus on divorce timing the findings of both studies are consistent with mine 4 my study adds to schmidt s by considering all women and men and exploring the differences between the genders including a discussion of how spousal characteristics might differ by the risk aversion of respondents

the benefit of crises for economic reforms when expenditures consistently outrun revenue the resulting inflation may have the effect of convincing the public and government that taxes must be raised to finance public investment in the advanced industrial countries income taxation and big spurts in taxation generally have become possible only under the impact of major emergency and crisis mostly in wartime in a number of developing countries in

the dynamics of marriage and divorce we formulate and estimate a dynamic model of marriage divorce and remarriage using panel data on two cohorts of danish men and women the marital surplus is identified from the probability of divorce and the surplus shares of husbands and wives from their willingness to enter marriage we find that the educations of husbands and wives are complements education raises the share of the marital surplus for men but not for women as men and women get older husbands receive a larger share of the marital surplus the estimated costs of divorce are high both early and late in marriage

marriage and class here we consider a matching model where agents are heterogeneous and utilities nontransferable we utilize this framework to study how equilibrium sorting takes place in marriage markets we impose conditions that guarantee the existence of a steady state equilibrium and then characterize it several examples are developed to illustrate the richness of equilibria the model reveals an interesting sorting externality that can support multiple steady state equilibria even with constant returns to matching excerpt

systematic and random search a synthesis this paper synthesizes two models of search in the labor market systematic and random we construct and test a theoretical model in which the searcher is endowed with information on some possibly zero or all individual firms in the labor market as well as the overall wage offer distribution we test the model using a special wave of the 1976 current population survey the major theoretical results of our model are as follows searchers with lower stocks of knowledge about individual firms higher discount rates or having lower coverage by unemployment insurance are more likely to engage in random search activities

who marries whom and why this paper proposes and estimates a static transferable utility model of the marriage market the model generates a nonparametric marriage matching function with spillover effects it rationalizes the standard interpretation of marriage rate regressions and points out its limitations the model was used to estimate u s marital behavior in 1971 72 and 1981 82 the marriage matching function estimates show that the gains to marriage for young adults fell substantially over the decade unlike contradictory marriage rate regression results the marriage matching function estimates showed that the legalization of abortion had a significant quantitative impact on the fall in the gains to marriage for young men and women

the displacement effect of reemployment bonus programs we develop a partial equilibrium matching model of the labor market in order to examine whether adoption of a reemployment bonus would displace workers not offered the bonus we examine the displacement effect for a unemployment insurance ui eligible workers who are offered but do not find a job in time to qualify for a bonus and b ui ineligible workers who are never offered a bonus the model predicts minimal displacement of the former group but for the latter group the model predicts an increase in unemployment duration of 2 4 week and an increase in unemployment of up to 2 per thousand

understanding economic policy reform one of the eventual consequences of the global debt crisis was a wave of market oriented economic reforms this paper discusses the state of our knowledge on the political economy of this process why were inefficient and often unsustainable policies maintained for so long why are so many governments reforming now after decades of adherence to policies of an opposite kind have the reformers internalized the correct lessons from the east asian experience finally are there any helpful rules for reformers to follow in guiding their policies through complicated political terrain

frictional assignment i efficiency abstract this paper examines the two sided matching problem where the agents on each side of the market are heterogeneous and the matching process is time consuming this is cast in a labor market setting where workers of different skills match with different machine qualities i characterize the efficient allocation and then show that it can be decentralized by a market mechanism the efficient assignment is not always positively assortative despite the fact that machine qualities and skills are complementary in production to decentralize the efficient allocation the market mechanism requires the firms to post wages and commit each machine quality to a particular skill implications on wage inequality are briefly examined journal of economic literature classification numbers j31 e24 j64

investment in schooling and the marriage market we present a model in which investment in schooling generates two kinds of returns the labor market return resulting from higher wages and a marriagemarket return defined as the impact of schooling on the marital surplus share one can extract men and women may have different incentives to invest in schooling because of different market wages or household roles this asymmetry can yield a mixed equilibrium with some educated individuals marrying uneducated spouses when the labor market returns to schooling rises home production demands less time and the traditional spousal labor division norms weaken more women may invest in schooling than men

environmental policy and the equilibrium rate of unemployment abstract this paper integrates environmental policy instruments with the theory of equilibrium unemployment we investigate the question of whether a low equilibrium rate of unemployment and a high quality of the environment are complementary policy goals or must be traded off it turns out that an interval exists for a tax on emissions where the two goals are indeed complementary the tax stimulates the emergence of an abatement sector which provides pollution control and vacancies for the job seekers for constrained efficiency the policy maker operates five instruments to internalize the environmental and the search externalities a tax on emissions employment subsidies and recruiting allowances for the polluting industries are sufficient to implement the first best the optimal emission tax is an increasing function of the workers bargaining strength for labor markets where workers have a strong bargaining position the optimal pollution tax may easily exceed the pigouvian tax

job contact networks abstract many workers hear about or obtain their jobs through friends and relatives the aim of this paper is twofold first we relate both individual and aggregate labor market outcomes to the network structure of personal contacts second we study strategic network formation to this purpose we develop a model specifying at the individual level both the decision to form contacts with other agents and the process by which information about jobs is obtained and transmitted we show that equilibrium networks always exist and that only moderate levels of network asymmetry can be sustained at equilibrium also we establish a general non monotonicity result on information flow and unemployment with respect to network size in symmetric networks

accounting for age in marital search decisions spouse quality measured by educational attainment varies significantly with the age at which an individual marries peaking in the mid twenties then declining through the early forties interestingly this decline is much sharper for women than men meaning women increasingly marry less educated men as they age moreover quality has worsened for educated women over several decades while it has improved for men using a non stationary sequential search model we identify and quantify the search frictions that generate these age dependent marriage outcomes we find that single life utility is typically the dominant friction though college women in the 1950 and 1970 cohorts are affected even more by deteriorating suitor quality regardless of educational status individual choice as opposed to pure luck is pivotal in explaining marriage market outcomes earlier in life

spatial mismatch search effort and urban spatial structure abstract the aim of this paper is to provide a new mechanism for the spatial mismatch hypothesis spatial mismatch can here be the result of optimizing behavior on the part of the labor market participants in particular the unemployed can choose low amounts of search and long term unemployment if they reside far away from jobs they choose voluntary not to relocate close to jobs because the short run gains low land rent and large housing consumption are big enough compared to the long run gains of residing near jobs higher probability of finding a job

an empirical investigation of the returns to job search the assumption of diminishing returns to job search plays a crucial role in the search model presented recently in this review by john seater this assumption is justified by noting that spatial aspects of the search process cause diminishing returns since travel time required to search firms in a circular area increases faster than the area to be searched besides being an important property of a class of theoretical models returns to search may partly explain the paradox of an approximately forty hour workweek contrasted with a seven hour search week see john barron and wesley mellow p 396 the interaction of diminishing returns to and positive costs of search may result in an optimal allocation of search time of only a few hours per week in this paper i examine whether the assumption of diminishing returns to job search can be supported by the data following seater the returns to search are measured by the number of firms contacted and the focus is on the ability of unemployed individuals to translate search time into employee contracts returns to search are evaluated by noting whether the production process exhibits diminishing returns with respect to the input variable

spatial mismatch transport mode and search decisions in england abstract we develop a theoretical model in which whites mainly use private vehicles to commute whereas nonwhites use public transportation we show that for both whites and nonwhites higher time distance to jobs leads to lower search effort because of different transport modes we also show that at exactly the same time distance to jobs white unemployed workers search more intensively than nonwhites because it is less costly for them to gather information about jobs we then test this model using english sub regional data we find that for each race indeed living in areas where distance to jobs is higher yields the unemployed to search less than in areas with better job access we also find that having access to a car increases search intensity for both whites and nonwhites finally closing the racial gap in car access and distance to jobs would considerably narrow the difference in search intensities between whites and nonwhites

an assessment of causal inference in smoking initiation research and a framework for future research i introduction the causal factors underlying youth smoking initiation are central to the challenge of developing effective smoking prevention programs and the shaping of many other types of smoking related policies these causal factors specifically the ones that potentially may be influenced by the conduct of cigarette manufacturers also have been a central issue in much of the recent smoking related litigation these high profile legal cases have focused on the claim that tobacco company conduct significantly influenced youth smoking initiation rates in particular cigarette advertising and tobacco company public reluctance to acknowledge the health risks of smoking have been purported to be key factors influencing youth smoking decisions 1 in this paper we examine the basic principles of empirical scientific investigation that have been adopted to establish causal relationships and apply these principles to evaluate the evidence underlying the link between cigarette advertising and youth smoking initiation the causal link between tobacco company marketing and youth smoking generally has been accepted as empirically established outside the economics literature despite the fact that the underlying evidence fails to meet commonly applied econometric standards we review some of these papers in the public health literature that have been cited as evidence supporting the causal link between cigarette advertising and youth smoking and explain why these papers fail to support this causal link further we also review the economics literature that provides evidence for a multicausal model for youth risky behaviors including smoking we identify studies in which researchers have found that many characteristics affecting choices to participate in risky behaviors are formed at very early ages empirical demonstration of causation is fundamental to guiding effective development of interventions in many areas of social life scientific principles are especially important for developing smoking related policies as enormous resources currently are being devoted to develop programs that attempt to reduce youth smoking propensities however many of these policies and suggested policies focus on causal factors that have not been scientifically established but rather merely assumed to affect smoking initiation more effective policies potentially could be developed by distinguishing causal factors through more reliable empirical methodologies without identifying factors that lead to smoking initiation through sound estimation techniques current prevention efforts may turn out to have little or muted benefits 2 ii causal factors of smoking initiation and the scientific model an important goal of policy analysis is to identify and measure causal relationships as many confounding correlations exist which do not reflect structural relations underlying actual outcomes understanding these underlying structural relations allows empirical versions of estimated models to more accurately forecast the effects of interventions as is well recognized in the econometrics literature precise identification and measurement of causal effects is a difficult task in the area of human choice since input parameters of investigated relationships may reflect unobserved individual characteristics and choices thus correlations between endogenous input parameters and observed outcomes may simply represent individual sorting on latent characteristics rather than structural relations between input and output variables many times in other disciplines biases associated with endogeneity do not hinder estimation of structural models because observed variables are not affected by individual choice for example to evaluate the effect of a particular drug on a particular disease researchers may be able to perfectly control factors such as the presence of other diseases dosage regimens alternative drug usage and diet

are training programs more effective when unemployment is high we estimate short run medium run and long run individual labor market effects of training programs for the unemployed by following program participation on a monthly basis over a 10 year period since analyzing the effectiveness of training over such a long period is impossible with experimental data we use an administrative database compiled for evaluating german training programs based on matching estimation adapted to address the various issues that arise in this particular context we find a clear positive relation between the effectiveness of the programs and the unemployment rate over time

the assignment of workers to jobs in an economy with coordination frictions this paper studies the assignment of heterogeneous workers to heterogeneous jobs owing to the anonymity of a large labor market workers use mixed strategies when applying for jobs this randomness generates coordination frictions two workers may apply for a particular job whereas an identical job gets no applications the model generates assortative matching with a positive but imperfect correlation between matched workers and firms types it predicts that a worker s wage is increasing in her job s productivity and a firm s profit is increasing in its employees productivity the model also yields a version of the welfare theorems

search method use by unemployed youth this article presents a search model which shows that search method choices should be related to their costs and expected productivities as well as to nonwage income and wage offer distributions the empirical evidence then shows that the most frequently used search methods i e friends and relatives and direct applications without referral are also the most productive in generating offers and acceptances the number of methods used is affected by factors that presumably reflect opportunities as well as income sources and needs specific methods are chosen in a manner that generates positive average effects on outcomes for those using them

wage differentials discrimination and efficiency abstract i analyze a large labor market where homogeneous firms post wages to direct the search of workers who differ in productivity i show that the model has a unique equilibrium the wage differential depends positively on the workers productivity differential only when the latter is large when the productivity differential is small high productivity workers get a lower wage than low productivity workers this reverse wage differential remains even when the productivity differential shrinks to zero however the equilibrium is socially efficient high productivity workers always get the employment priority and higher expected wages than low productivity workers although discrimination in terms of expected wages does not exist conventional measures are likely to incorrectly find discrimination in the model

differntial fecundity markets and gender roles women are fecund for a shorter period of their lives than men this paper investigates how differential fecundity interacts with marriage labor and financial markets to affect gender roles the main findings of the paper are as follows i fecund women are relatively scarce men will behave differently than women in response to this scarcity in the most fundamental way demand and supply conditions in the marriage market affect gender roles ii differential fecundity does not have any market invariant gender effect gender roles depend on the way in which marriage labor and financial markets interact iii gender differences in the labor market can occur without corresponding differences in labor market opportunities productivities in child rearing or social norms iv with uncertainty in human capital accumulation and no insurance against this uncertainty the model s predictions are consistent with observed gender roles

on the job search some empirical evidence from britain abstract this paper considers evidence from the labour force survey concerning job search by employed workers the unconditional probability of observing on the job search is decomposed into the product of two constituent probabilities upon which maximum likelihood estimation is performed the analysis facilitates the identification of who searches and whether search takes place in work or from unemployment temporary or part time employment encourages continued search by men but not women skilled workers search more than the unskilled and demonstrate a preference for employed search inter industry wage relativities encourage search on the job job tenure is a significant determinant of the quality of a job match and the subsequent likelihood that on the job search is undertaken employed job seekers adopt search strategies that are more readily integrated into a working environment

evaluating the employment impact of a mandatory job search program this paper exploits area based piloting and age related eligibility rules to identify treatment effects of a labor market program the new deal for young people in the u k a central focus is on substitution displacement effects and on equilibrium wage effects the program includes extensive job assistance and wage subsidies to employers we find that the impact of the program significantly raised transitions to employment by about 5 percentage points the impact is robust to a wide variety of nonexperimental estimators however we present some evidence that this effect may not be as large in the longer run jel j18 j23 j38

an empirical model of employed search unemployed search and nonsearch the 1969 1971 national longitudinal surveys data on young men were used to study the employed worker s choice among employed search unemployed search and not searching for a new job we assume that an unobserved variable search intensity governs this choice such that unemployed search involves a greater intensity than employed search which of course is associated with greater intensity than nonsearch the principal results are that current wages seniority collective bargaining coverage employment outside construction and employment by government are each ceteris paribus negatively associated with search intensity further each of these variables lowers the probability of not searching and raises the probabilities of employed and unemployed job search

dynamic marriage matching an empirical framework the paper proposes a dynamic version of the frictionless becker shapley shubik marriage matching model with transferable utility its primary objective is to develop a tractable model that rationalizes the marriage distribution of who marries whom by age this behavioral dynamic model rationalizes a new marriage matching function an empirical methodology that relies on the equilibrium outcomes of the model identies the marital preferences over spouses this framework also allows the inverse problem of computing the vector of aggregate marriages given a new distribution of available single individuals and estimated preferences to be solved the solution to this inverse problem has been shown to exist under mild conditions this paper also develops a simple test of the model s empirical validity using aggregate data of new marriages and available single men and women in the us in 1970 1980 and 1990 i investigate the changes in the gains to marriage over this period

on the state of the union an overlapping generations model of marriage and divorce is constructed to analyze family structure and intergenerational mobility agents differ by sex marital status and human capital single agents meet in a marriage market and decide whether to accept or reject proposals to wed married couples must decide whether to separate or not parents invest in their children depending on their wherewithal a simulated version of the theoretical prototype can generate an equilibrium with a significant number of female headed families and a high degree of persistence in income across generations to illustrate the model s mechanics the effects of two antipoverty policies namely child support and welfare are investigated

the effect of male wage inequality on female age at first marriage a model in which women search for husbands characterized by their wages predicts increasing within group male wage inequality raises the expected value of continued marital search and so lowers female marriage propensities using 1970 1980 and 1990 census data i test this hypothesis within geographically racially and educationally defined marriage markets the estimates suggest rising male wage inequality accounted for 7 to 18 of the decline in the propensity to marry between 1970 and 1990 for white women and more educated black women growing wage inequality appears to have had little effect on the marriage behavior of less educated black women

unemployment dynamics and labour market tightness an empirical evaluation of matching function models the implications of matching function models for the relationship between labour market tightness and the transition probability into employment are summarized these implications are then tested using monthly data for three canadian provinces british columbia ontario and quebec testing methods use flexible regression techniques so as to reduce the effect of any extraneous restrictions the results show rough concordance between theoretical assumptions and empirical facts evidence of non linearity in the estimated relationships favours a search theoretic model of labour markets over one based on queues and some quantitative results offer guidance to those using calibrated search models in theoretical analysis

distributional coalitions and the politics of economic reform in latin america for much of the discipline of economics a closed economy is seen as the result of efforts of distributional coalitions and rent seekers to maintain sector specific protections accordingly economic liberalization is explained by the policy consistency of uncompromising reform elites students of the politics of economic adjustment in the developing world in turn have argued that reform programs concentrate costs in the present and disperse benefits in the future hence losers are prepared to engage in collective action whereas prospective winners facing uncertainty about payoffs remain disorganized they thus posit the cohesiveness and insularity of policymakers as the main variable for explaining successful reform both economists and political scientists therefore adopt a collective action approach that overlooks how groups organize in support of liberalization in the recent latin american experience however these reforms have preserved market reserves for firms that provided vital political support to and often colluded with policymaking elites this setting has thus reproduced incentives for rent seeking behavior even in the presence of comprehensive liberalization this evidence supports two interrelated theoretical claims first distributional coalitions may proliferate when the state withdraws from the economy not only when it intervenes second interest based variables retain explanatory power in political economy which state autonomy arguments disregard irrespective of whether the economy is closed or open which neoclassical perspectives overlook to highlight the centrality of interest groups favoring marketization therefore the article suggests modifications to the dominant theories of collective action and the literature on the politics of economic adjustment

credibility and stabilization the paper deals with stabilization as a one shot problem to ask what credibility means in a world where programs will succeed with probability one a model is spelled out where the equilibrium program has some ex ante probability of failure the model draws attention to the factors that raise or lower the probability of success of a stabilization program and thus offers a positive theory of stabilization reputation that emerges as a central element in repeated games has no role in this model

on the job search in a recession this paper is concerned with the behavious of one component of employee job search in one local labour market during a period of severe recession the paper focuses on the relationship between market conditions and the number of employees using the services of employment offices and jobcentres in analysing this relationship over time the paper stresses the need to adopt a flow approach in such empirical studies of the labour market often as in this case explanatory variables can affect inflows and outflows to labour market stocks in different directions and misleading conclusions may therefore be drawn if only the traditional stock analysis is conducted a further concern of the paper is to examine whether the relationship between market conditions and job search differs between male and female employees

optimal unemployment insurance abstract we investigate the design of an optimal unemployment insurance program using an equilibrium search model calibrated using data from the reemployment bonus experiments there are three main conclusions first insurance considerations suggest that the potential duration of ul benefits would be unlimited under an optimal program second if the potential duration to benefits were unlimited current replacement rates in the u s about 0 5 would probably be about right third the optimal replacement rate rises as the potential duration of benefits is increasingly limited reaching 1 when the potential duration of benefits is limited to 32 weeks
