Marginal Employment, i.e. employment at low working hours and earnings not covered by social security, has been gaining importance in the German economy over the past decade. Using a large newly available panel data set and statistical matching techniques, we analyse the effects of marginal...

Traditional labour supply theories stress economic variables as unemployment and wages to explain differences inlabour supply behaviour. Nowadays a number of trends can be observed in the literature about labour supply theoryand modelling: the integration of market-based and power based...

In our increasingly interconnected and open world, international migration is becoming an important socio-economic phenomenon for many countries. Since the early 1980s, many studies have been undertaken of the impact of immigration on host labour markets. Borjas (2003) noted that the estimated...

This paper studies how social relationships between managers and employees affect relational incentive contracts. To this end we develop a simple dynamic principal-agent model where both players may have feelings of altruism or spite toward each other. The contract may contain two types of...

When workers send applications to vacancies they create a network. Frictionsarise because workers typically do not know where other workers apply to and firmsdo not know which candidates other firms consider. The first coordination frictionaffects network formation, while the second coordination...

In this paper we determine the feasibility of using data from thePanel Study of Income Dynamics to estimate the Burdett-Mortensengeneral equilibrium search model. The data contain sufficientinformation on wages, labor force states, durations, and transitionsto generate estimates of the model's...

We present an equilibrium-search model with heterogenous workers whosearch for a job in one of two sectors and who lose part of theirskills during unemployment. We show that an import tariff increasethe wage and the employment prospects in the protected sector. Thisresults in a labor market...

This paper examines the use of equilibrium search models in the empiricalanalysis of labor markets. We survey the literature on structural estimationof these models with micro data on wages and durations, and we discuss theadvantages of the equilibrium approach, for policy analysis and...
