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...

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...

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

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...

We introduce different skill groups and production functions into the Burdett-Mortensen equilibrium search model. Supermodularity in the production process leads to a positive intrafirm wage correlation between skill groups. Theory implies that increasing returns to scale can lead to a unimodal...

We study the effects of employment protection taking into account that firms can invest in R&D or buy new technologies in order to restore their productivity. To do so we develop an equilibrium matching model with an imperfect labor and innovation market. If employment protection is introduced,...

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...
