In January 2005, the German Supreme Court permitted the state governments to charge tuition fees. By exploiting the natural experiment, we examine how government ideology influenced tuition fee policy. The results show that right-wing governments were active in introducing tuition fees. By...

We modify the principal-agent model with moral hazard by assuming that the agent is expectation-based loss averse according to K o szegi and Rabin (2006, 2007). The optimal contract is a binary payment scheme even for a rich performance measure, where standard preferences predict a fully...

We consider a monopolistic supplier’s optimal choice of wholesale tariffs when downstream firms are privately informed about their retail costs. Under discriminatory pricing, downstream firms that differ in their ex ante distribution of retail costs are offered different tariffs. Under uniform...

The extant theory on price discrimination in input markets takes the structure of the downstream industry as exogenously given. This paper endogenizes the structure of the downstream industry and examines the effects of permitting third-degree price discrimination on market structure and...

We propose a theory of ex post inefficient renegotiation that is based on loss aversion. When two parties write a long-term contract that has to be renegotiated after the realization of the state of the world, they take the initial contract as a reference point to which they compare gains and...

Earlier study has shown that procrastination can be explained by quasi-hyperbolic discounting. We present a model of effort choice over time that shifts the focus from completion of to performance on a single task. We find that being aware of the own self-control problems may reduce a person’s...
