German policy during the Eurozone crisis supposedly follows an ordoliberal tradition. In this paper, we discuss to what extent this contention holds and to what extent Germany pragmatically responded to different crisis phenomena. A proper analysis of ordoliberal thinking reveals that the...

A nudge is a non-coercive paternalistic intervention that attempts to improve choices by manipulating the framing of a decision problem. As any paternalism, it faces the difficulty of determining the appropriate welfare criterion. We propose a welfare-theoretic foundation for nudging similar in...

This paper models the strategic interaction between a rating agency, a bank and a bank regulator who lacks information about bank asset risk. The regulator can either (1) make bank capital requirements contingent on credit ratings; or (2) set rating-independent capital requirements. Truthful...

Using a calibrated overlapping generations model we quantify the welfare gains of an age dependent income tax. Agents face uncertainty regarding future abilities and can by saving transfer consumption across periods. The welfare gain of switching from an age-independent to an age-dependent...

We study the optimal duration of contracts in a principal-agent framework with both moral hazard and adverse selection. Agents decide on a contract-specific and non-verifiable investment. Incentive compatibility requires that initial contracts, which serve to screen the ability of newly hired...

The well known Pareto criterion used in the context of efficiency and welfare has to do with absolute changes whereas in every domain of economic behaviour inequality or relative changes has become a major concern. We propose an inequality-preserving or distribution neutral Pareto criterion-the...

In this paper, we analyze the consequences of delays and cost overruns typically associated with the provision of public infrastructure in the context of a growing economy. Our results indicate that uncertainty about the arrival of public capital can more than offset its positive spillovers for...

Paternalism is an attempt to influence individuals' decisions for their own benefit, even if there are no third parties involved. This seems to contradict normative individualism, which provides the general orientation to our modern democracies. Soft or libertarian paternalism accepts the...

We study welfare effects of public short-time compensation (STC) in a model in which firms respond to idiosyncratic profitability shocks by adjusting employment and hours per worker. Introducing STC substantially improves welfare by mitigating distortions caused by public unemployment insurance...
