This paper examines the determinants of gross labour flows in a context where modeling the migration decision as a wage-maximizing process may be inadequate due to regional wage rigidities that result from central wage bargaining. In such a context, the framework that has been developed by...

In 1976 Vaubel suggested using the variation of real exchange rates when evaluating the desirability of a monetary union within a group of currencies (Vaubel 1976). Currency uni cation is less desirable, the more often real exchange rate adjustments are needed. Ten years later, Mussa...

What is the optimal size of expert committees? To address this question, I present a model of a committee of experts with career concerns. Each expert may observe an argument about the state of the world and is unsure about the argument s soundness. Experts may remain silent or compete for the...

We study an exchange economy with overlapping generations of consumers who derive utility from consuming a non-durable commodity and housing. A banking sector offers loans to finance housing. We provide a complete characterization of the equilibrium dynamics which alternates between an expansive...

This paper investigates the role of social identity in reactions to control. We propose a simple principal-agent model with control that incorporates the existence of social groups. Our laboratory experiment shows that, in contrast to no-group agents, agents in social groups (i) perform better;...

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 theory of relationship lending is based on the idea that close ties between borrowers and banks may be economically beneficial. Information asymmetries on the part of the bank introduce adverse selection and moral hazard problems into the lending process and may lead to lengthy decision...

We examine the herd behavior among equity funds in Germany based on a large sample of funds from 2000 to 2009. We show that a large portion of the detected herding can be explained by identical trading among funds of the same investment company. However, we also find statistically significant...

The Taylor rule is a widely used concept in monetary macroeconomics and has been used in various areas either for positive or normative analyses. We examine whether the robustifying nature of Taylor rule cross-checking in the spirit of R island and Sveen (2011) also carries over to the case of...

This paper investigates optimal policy in the presence of anticipated (or news) shocks. We determine the optimal unrestricted and restricted policy response in a general rational expectations model and show that, if shocks are news shocks, the optimal unrestricted control rule under commitment...
