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 ...
Working-time political debates often focus on options for flexible and variable working hours. Meanwhile, employees' desire for more time sovereignty is gaining relevance. Although working time preferences and their impact on the German labor market are investigated in numerous studies, findings are inconsistent, varying with the data set, including the formulation and placement of questions in the ...
Using the 41-year division of Germany as a natural experiment, we show that the GDR’s gender-equal institutions created a culture that has undone the male breadwinner norm and its consequences. Since reunification, East Germany still differs from West Germany not only by a higher female contribution to household income, but also because East German women can earn more than their husbands without having ...
