This paper studies the impact of collaboration on research output. First, we build a micro founded model for scientific knowledge production, where collaboration between researchers is represented by a bipartite network. The equilibrium of the game incorporates both the complementarity effect...

In the presence of even small moral hazard, Hansen & Imrohoroglu (1992) show that the unemployment insurance should be much less generous than without moral hazard. This has important implications in the light of recent reforms. We question this result by adding a social component to the model:...

**The following is a description of the paper and not the actual abstract.** Why are business cycles statistics so different from one country to the other, at least for trade related variables? This paper tries to replicate this feature of the data in an international real business cycle model...

Der Druck auf mittelständische Unternehmen, ihr Führungs- und Steuerungssystem zu professionalisieren, wird immer stärker. Zunehmendes Interesse an Start Ups, anhaltende Outsourcing-Aktivitäten von Großunternehmen, veränderte gesetzliche Rahmenbedingungen und neue Spielregeln des...

This document describes the data collection and use of data for the computation of rankings within RePEc (Research Papers in Economics). This encompasses the determination of impact factors for journals and working paper series, as well as the ranking of authors, institutions, and geographic...

Unemployment insurance policies are multidimensional objects. They are typically defined by waiting periods, eligibility duration, benefit levels and asset tests when eligible, which make intertemporal or international comparisons difficult. To make things worse, labor market conditions, such as...

We study the impact of global climate change on the prevalence of tropical diseases using a heterogeneous agent dynamic general equilibrium model. In our framework, households can take actions (e.g., purchasing bednets or other goods) that provide partial protection from disease. However, these...
