We analyze dynamic price competition in a homogeneous goods duopoly, where consumers exchange information via word-of-mouth communication. A fraction of consumers, who do not learn any new information, remain locked-in at their previous supplier in each period. We analyze Markov perfect...

Federal states in Germany are characterized by low fiscal autonomy. Equalization systems in place balance revenue differences to a considerable extent and states cannot independently set taxes of any major relevance. Although these features of German federalism are notorious for their...

In this paper, we empirically examine a heterogenous bounded rationality version of a hybrid New-Keynesian model. The model is estimated via the simulated method of moments using Euro Area data from 1975Q1 to 2009Q4. It is generally assumed that agents' beliefs display waves of optimism and...

I add a moral hazard problem between banks and depositors as in Gertler and Karadi (2009) to a DSGE model with a costly state verification problem between entrepreneurs and banks as in Bernanke et al. (1999) (BGG). This modification amplifies the response of the external finance premium and the...

The generic alliance game considers players in an alliance who fight against an external enemy. After victory, the alliance may break up, and its members fight against each other about the spoils of the victory. Our experimental analysis of this game shows: In-group solidarity vanishes after the...

In this paper, citizens vote in order to influence the election outcome and in order to signal their unobserved characteristics to others. The model is one of rational voting and generates the following predictions: (i) The paradox of not voting does not arise, because the benefit of voting does...

We introduce publicly funded education into R&D based economic growth theory. Our framework allows us to i) explicitly describe a realistic process of human capital accumulation within these types of growth models, ii) reconcile semi-endogenous growth theory with the empirical evidence on the...

Combining a spatial equilibrium model with a matching unemployment model, this paper analyzes the regional quality of life when wages, rents, and unemployment risk compensate for local amenities and disamenities. In particular, the paper shows for quasi-linear utility that the effects of any...

The paper analyzes the interaction between an endogenous capital structure and investment decision, and the incentive scheme of bank executives. We show that the implementation of capital requirements, which are contingent on compensation schemes, drive a wedge between the interests of the...

This paper is the first to estimate the effect of one partner's entry into unemployment on the mental health of both spouses in Germany. In order to give the estimates a causal interpretation, this study focuses on an exogenous entry into unemployment (plant closure) and applies a...
