In this study we develop and calibrate a search and matching model of the German labour market and analyze the impact of recent immigration. Our model has two production sectors (manufacturing and services), two skill groups and two ethnic groups of workers (natives and immigrants). Moreover, we...

This paper develops a labour market model with on-the-job search, match-specific productivity draws and an endogenous irreversible schooling decision. The choice of schooling is modelled as an optimal stopping problem which gives rise to the equilibrium heterogeneity of workers with respect to...

This paper develops a matching model of the labor market with heterogeneous firms, on-the-job search and family referrals. The overall effect of referrals on wages can be decomposed into three distinct components. First, if referrals are used to help unemployed partners find jobs, then...

This paper develops a labour market matching model with heterogeneous firms, on-thejob search and referrals. Social capital is endogenous, so that better connected workers bargain higher wages for a given level of productivity. This is a positive effect of referrals on reservation wages. At the...

This study explores the relationship between firms' characteristics and their recruitment strategies. We propose a model based on a search and matching framework with two search channels: a formal channel which is costly for firms and a costless informal channel, i.e. referrals. There is a...

In this study we evaluate the effects of low-skilled immigration on small businesses, wages and employment in Germany. We develop a search and matching model with heterogeneous workers, cross-skill matching, and endogenous entry into entrepreneurship. The model is calibrated using German...

This paper incorporates job search through personal contacts into an equilibrium matching model with a segregated labour market. Job search in the public submarket is competitive which is in contrast with the bargaining nature of wages in the informal job market. Moreover, the social capital of...

This paper incorporates a classical moral hazard problem with unobserved worker effort and bonus payments into a competitive search equilibrium environment with risk averse workers. The resulting framework permits an analysis of the effects of labour market competition and search frictions on...

This paper revisits the no-attachment assumption in job search models with random productivity fluctuations and Nash-bargaining. Both workers and firms value the option to remain in attachment: firms profit from a reduced hiring cost, while workers gain from a higher reservation wage when...
