In this paper we introduce the cost channel of monetary policy (e.g., Ravenna and Walsh, 2006) into an otherwise standard New Keynesian model of a two-country monetary union, which is being hit by aggregate, asymmetric and idiosyncratic shocks. The single central bank implements the optimal...

Die Verlagerung von der ambulanten zur stationären Pflege ist eine der Hauptursachen für die Ausgabensteigerungen der gesetzlichen Pflegeversicherung. Um diesen so genannten Heimsog zu reduzieren, haben die Pflegekassen ein Modellprojekt Personengebundenes Pflegebudgetinitiiert, das über ein...

Eines der zentralen Probleme der Finanzwissenschaft ist die Frage nach der wohlfahrtsmaximalen Politik des Staates. Als Versuch einer Antwort wird im wachstumstheoretischen Kontext des Modells überlappender Generationen die optimale Finanzpolitik entworfen, die sich als simultanes Optimum von...

Empirical evidence suggests that the bargaining power of trade unions differs across firms and sectors. Standard models of unionization ignore this pattern by assuming a uniform bargaining strength. In this paper, we incorporate union heterogeneity into a Melitz (2003) type model. Union...

Empirical evidence suggests that high-productivity firms face stronger trade unions than low-productivity firms. Then a policy that puts all unions into a better bargaining position is no longer neutral for firm selection as in models with a uniform bargaining strength across firms. Using a...

In almost all Western economies the median age of the workforce is increasing due to demographic factors. Given the empirical fact that workers of different ages are not perfect substitutes in production, this paper explores how change in the age pattern affects wages and (un)employment. We...

Ist die Arbeitsnachfragekurve eher steil oder eher flach? Die diesbezüglichen Überlegungen von John Hicks (1932) und Alfred Marshall (1920) haben nichts an Aktualität verloren. Ihre vier Gesetze der Nachfrage sind nach wie vor Ausgangspunkt vieler Studien zur Theorie und Empirie der...

It is well known that profit sharing arrangements Pareto-dominate fixed wage contracts. Share agreements are (far) less than ubiquitous, however. This paper offers a solution of this 'fixed wage' by adopting a perspective of bounded rationality. We show that share arrangements that fulfill...
