This paper reviews a new framework for analyzing the interrelationship between inequality, unemployment, labor market frictions, and foreign trade. This framework emphasizes firm heterogeneity and search and matching frictions in labor markets. It implies that the opening of trade may raise...

In order to explore the optimal taxation of low-skilled labour, we extend the standard model of optimal non-linear income taxation in the presence of quasi-linear preferences in leisure by allowing for in-voluntary unemployment, job search, an exogenous welfare benefit, and a non-utilitarian...

We evaluate a randomized experiment of a statistical support system developed to assist caseworkers in Swiss employment offices in choosing appropriate active labour market programmes for their unemployed clients. This statistical support system predicted the labour market outcome for each...

In many countries, caseworkers in a public employment office have the dual roles of counselling and monitoring unemployed persons. These roles often conflict with each other leading to important case-worker heterogeneity: Some consider providing services to their clients and satisfying their...

We study a two-country two-sector model of international trade in which one sector produces homogeneous products while the other produces differentiated products. The differentiated-product industry has firm heterogeneity, monopolistic competition, search and matching in its labor market, and...

This Paper analyses the labour mobility and human capital accumulation of male immigrants who moved from the former Soviet Union to Israel. We formulate an estimable dynamic choice model for employment and training in blue and white-collar occupations, where the labour market randomly offered...

Does capital-embodied technological change play an important role in shaping labour market inequalities? This Paper addresses the question in a model with vintage capital and search/matching frictions where costly capital investment leads to large heterogeneity in productivity among vacancies in...

We present a theoretical and empirical analysis of different types of active labour market policies (ALMP). In our empirical analysis we use data on 20 OECD countries covering the time period 1985-99. We find that labour market training is the most effective program to bring down unemployment....

This Paper presents a theory and an empirical investigation on cyclical fluctuations in workplace accidents. The theory is based on the idea that reporting an accident dents the reputation of a worker and raises the probability that he is fired. Therefore a country with a high or an increasing...

Do government provided training programmes benefit the participants and the society? We address this question in the context of female immigrants who first learn the new language and then choose between working or attending government provided training. Although theoretically training may have...
