Specification and Estimation of Equilibrium Search Models

This paper considers estimation of a pure equilibrium search model in which all heterogeneity is endogenous and due to information asymmetries, and of variations that allow better fits to the data: Measurement error and heterogeneity in the productivity levels of firms. The model is fit to a random sample of individuals representing 1% of the Danish population in the age group 16–75 years over the period 1981–1990. All specifications are fit by maximum likelihood and provide readily interpretable parameter estimates. Variation in estimates across demographic groups is discussed. Several parameters are common across specifications, and their estimates are reasonably robust.

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.     

An Empirical Equilibrium Job Search Model With Search on the Job and Heterogeneous Workers and Firms

In this article we present and estimate a synthesis of previous equilibrium search models, allowing for continuous distributions of workers' opportunity costs of employment as well as firms' productivities. The model allows for on-the-job search, and we assume that job offer arrival rates for workers are independent of their labor-market state. We derive the theoretical implications of these assumptions, we provide simulations, and we develop a semiparametric estimation procedure that we apply to a dataset of individual labor-market histories.     

Equilibrium Directed Search with Multiple Applications

We analyse a model of equilibrium directed search in a large labour market. Each worker, observing the wages posted at all vacancies, makes a fixed, finite number of applications, a . We allow for the possibility of ex post competition should more than one vacancy want to hire the same worker. For each a , there is a unique symmetric equilibrium in which all vacancies post the same wage. When a = 1, the common posted wage lies between the competitive and monopsony levels, and equilibrium is efficient. When a > 1, all vacancies post the monopsony wage. Some workers fail to find a job, some find a job at the monopsony wage, and some—those for whom there is competition—get the competitive wage. Equilibrium is inefficient when a > 1; in particular, there is excessive vacancy creation.     

Labour Market Efficiency with Discriminatory Unions

The paper considers 'efficient bargains', with a union that weighs the utilities of its members unequally and negotiates over group employment levels. Such discrimination may lead to socially inefficient overemployment of the dominant group, and underemployment of the group suffering discrimination.     

基于劳动力市场分割的劳动力流动模型的构建

国内外学者对于劳动力流动进行了大量深入的研究,成果颇丰.然而,由于历史的原因,我国在劳动力流动方面呈现出与其他国家不同的特性,目前,我国的劳动力市场尚未发展成熟,劳动力流动存在很严重的不合理现象.因此,结合我国的现实情况对其进行研究意义更加重大.本文试图结合以往学者的研究成果,构建基于劳动力市场分割的劳动力流动模型,对其进行深入的探讨,为实现劳动力的合理流动提供帮助.     

The Happiness of Young Australians: Empirical Evidence on the Role of Labour Market Experience

Data from the Longitudinal Surveys of Australian Youth are used to investigate factors that influence young Australians' self-reported levels of 'happiness' during the school-to-work transition, focusing on the role of labour market experience. Panel logit models are fitted to control for individual effects. Fixed individual personality traits and marital status strongly influence reported happiness. There is evidence of declining well-being with duration of unemployment and of the importance of job quality, rather than just having a job. The validity of Clark and Oswald's (1994) assertion that empirical findings from happiness research show that unemployment is involuntary is questioned.     

Labour Market Policies and Long-term Unemployment in a Flow Model of the Australian Labour Market

This paper develops a general equilibrium job matching model, which is used to assess the impact of active labour market policies, reductions in unemployment benefits and reductions in worker bargaining power on long-term unemployment and other key macro variables. The model is calibrated using Australian data. Simulation experiments are conducted through impulse response analysis. The simulations suggest that active labour market programs (ALMPs) targeted at the long-term unemployed have a small net impact and produce adverse spillover effects on short-term unemployment. Reducing the level of unemployment benefits relative to wages and worker bargaining power have more substantial effects on total and long-term unemployment and none of the spillover effects of ALMPs.     

Migration and Labour Market Adjustment: Empirical evidence from Finland 1985‐90

This paper addresses the question of the role of migration as an adjustment process by analysing the relationship between unemployment and labour force mobility. The empirical analysis deals with long-distance migration in Finland in the period 1985-90. When considered within a multivariate setting in which personal and place characteristics are held constant, the results show that higher origin unemployment rates increase outmigration, but not particularly for unemployed workers. Three outcomes are deduced from the results. First, the equilibrating process of interregional migration is slow-although working in the right direction-and becomes steadily slower as regional unemployment differentials fall. Secondly, the size of high-unemployment regions, as measured in terms of the labour force, decreases during the adjustment process as employed persons also leave the region. Thirdly, high-unemployment regions in particular lose their young and educated workers. The danger of the process of cumulative causation is great in these regions.     

Labor Taxation in Search Equilibrium with Home Production

Conventional models of equilibrium unemployment typically imply that proportional taxes on labor earnings are neutral with respect to unemployment as long as the tax does not affect the replacement rate provided by unemployment insurance, i.e. unemployment benefits relative to after–tax earnings. When home production is an option, the conventional results may no longer hold. This paper uses a search equilibrium model with home production to examine the employment and welfare implications of labor taxes. The employment effect of a rise in a proportional tax is found to be negative for sufficiently low replacement rates, whereas it is ambiguous for moderate and high replacement rates. Numerical calibrations of the model indicate that employment generally falls when labor taxes are raised.
