The impact of a stronger work requirement for welfare recipients in a workfare program is studied in an efficiency wage model where a representative firm chooses its level of monitoring activities. A stricter workfare policy raises employment and monitoring activities. It typically increases...

The impacts of introducing or tightening time limits on welfare use are studied in an efficiency wage model. Those losing access to regular benefits receive some smaller benefit, which can be interpreted as food stamps. Stricter time limits raise both employment and profits and generally reduce...

The forces of the market and systems competition bring about economic and social convergence in Europe. There is no need for social policies at the EU level. Social harmonisation would distort migration flows and slow down the speed of economic convergence. National welfare states will be...

We use the German Job Vacancy Survey to investigate whether firms are able to attract more suitable applicants by offering bargain wages rather than posting fixed wages. Contrary to the theoretical predictions provided by the literature, we find that the offer to bargain over pay decreases the...

Models of random search, directed search, or stock-ow matching differ substantially in the way they assume that job seekers and firms behave during the recruitment process. In this paper we identify new patterns about the recruitment behaviour of firms using the entropy balancing technique and...

The German Federal government has allowed some regions (Approved Local Providers) to be solely responsible for the care of long-term unemployed. The remaining regions had to form Joint Local Agencies, where the local social benefit administrations work together with the local public employment...

When workers send applications to vacancies they create a network. Frictions arise if workers do not know where other workers apply to (this affects network creation) and firms do not know which candidates other firms consider (this affects network clearing). We show that those frictions and the...

Convex vacancy creation costs shape firms' responses to trade liberalization. They induce capacity constraints by increasing firms' cost of production, leading a profit maximizing firm not to fully meet the increased foreign demand. Hence, firms will only serve a few export markets. More...

The Public Employment Agency (PEA) helps unemployed to find work and mediates PEA-registered job vacancies to job seekers via vacancy referrals. Using the spatial and temporal variation resulting from the regional roll-out of the Hartz 3 reform we are able to show that Hartz 3, which changed...

We develop and empirically test a labor market model with Public Employment Agencies (PEA) in order to understand why not all vacancies use the costless services provided by the PEA. We show that both the search market and the PEA can be active in equilibrium. In such an equilibrium, workers...
