In the last years, there has been a shift from traditional measurements of affective well-being to approaches such as the day reconstruction method (DRM). While the traditional approaches often assess trait level differences in well-being, the DRM allows examining affective dynamics in everyday contexts. The latter may ultimately explain why some people feel more happy than others (e.g., because they ...
This paper analyzes the effect of a recently introduced policy reform on participation in integration courses and on certified language proficiency levels among refugees in Germany. The residence rule restricts initial residence for refugees with a permanent residence permit. Given that treatment intensity varies distinctly across states, I utilize this quasi-experiment and apply a difference-in-differences ...
This course provides a thorough exposition to complementarity models and their solution techniques. It covers algebraic and geometrical interpretations of optimality conditions, equilibria, mathematical programs with equilibrium constraints, and equilibrium problems with equilibrium constraints. It will apply the concepts to the analysis of electricity markets.The course is designed for PhD...
We investigate the impact of competition policy enforcement on the functioning of European energy markets while accounting for sectoral regulation. For this purpose, we compile a novel dataset on the European Commission's (EC) and EU member states' competition policy decisions in energy markets and combine it with firm- and sector-level data. We find that EC merger policy has a positive and robust ...
Second generation rent control seeks to prevent negative quantity effects by exempting newly built units. The artificially lowered rent in the controlled segment makes renting attractive for households that would otherwise not have rented in the market, replacing households with higher willingness to pay for housing. These households bid up prices in the free market segment, giving rise to an opposite-sign ...
Using an experiment, we demonstrate that a communication regime in which a worker communicates about his intended effort is less effective in: (i) soliciting truthful information; and (ii) motivating effort than one in which he communicates about his past effort. Our experiment uses a real-effort task, which additionally allows us to demonstrate the effects of communication on effort over time. We ...
