The self-employed constitute a large proportion of the workforce in developing countries and the sector has been found to be growing further. Different accounts exist as to the cause of this development, with pull factors such as high returns to capital and increased wealth contrasted with push...

This paper investigates the degree of monoposony power of German employers in different industries, using a semi-structural approach based on a dynamic model of monopsonistic competition. The empirical analysis is based on a linked employer-employee data set which allows us to control for...

This paper investigates the behaviour of employers' monopsony power and workers' wages over the business cycle. Using German administrative linked employer--employee data for the years 1985--2010 and an estimation framework based on duration models, we construct a time series of the firm-level...

We use a 100% sample of social security panel micro data for estimating the effects of a minimum wage in the German construction sector. In 1997, a wage floor was introduced at different rates in West and East Germany. For analysing the impact of this natural experiment we conceptually follow a...

We introduce a dynamic treatment to the mixed proportional hazard competing risks model and allow for selection on unobservables. Our model can e.g. be used to evaluate the effect of benefit sanctions on the transition rate out of unemployment when more than one exit risk is of interest....

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...

Empirical studies find that the age-variance profile of wages is U-shaped. The objective of this paper is to explore the driving forces of the U-shape in a model with search frictions. I introduce endogenous search effort and a fixed retirement age into Cahuc, Postel-Vinay, and Robin s (2006)...

The German employment miracle with a weak decline in employment and low unemployment during the great recession seems to be a good example for a successful labour market reform. While the aggregate level of job turnover seems to be stable over time, there are nevertheless concerns about rising...

This paper investigates immigrants and natives labour supply to the firm within a semi-structural approach based on a dynamic monopsony framework. Applying duration models to a large administrative employer employee data set for Germany, we find that once accounting for unobserved worker...

The new training literature suggests that in a monopsonistic market employers will not only pay for firm-specific training but also for general training if the risk of poaching is limited. This implies that training participation should decrease when competition for employees is higher among...
