This paper investigates competition between health insurance companies under different financing regulations. We consider two alternatives advanced in recent German health care reform discussions: competition by contribution rates (health contributions) and by fees (health premia). We find that...

We explore the determinants and effects of trust relationships between upstream suppliers and downstream producers. Using unique survey data on individual supplier-buyer relationships in the German automotive industry, we show, by means of different measures of supplier-buyer trust, that higher...

We show that professional soccer players exhibit reference-dependent behavior during matches. Controlling for the state of the match and for unobserved heterogeneity, we show on a minute-by-minute basis that a player breaches the rules of the game, measured by the referee's assignment of cards,...

Corporate tax reforms carried out in EU countries since 1980 entail lower statutory tax rates and reductions in generous tax depreciation provisions. Several countries including the UK have reduced tax rates for SMEs. This study compares incentive effects of such reforms on the SMEs? investment...

We model the evolution of the number of individuals that are reported to be sick with COVID-19 in Germany. Our theoretical framework builds on a continuous time Markov chain with four states: healthy without infection, sick, healthy after recovery or after infection but without symptoms and...

We examine how new airport infrastructure influences regional tourism. Identification is based on the conversion of a military air base into a regional commercial airport in the German state of Bavaria. The new airport opened in 2007 and promotes travelling to the touristic region Allgäu in the...

This paper develops a dynamic stochastic general equilibrium model to examine the quantitative macroeconomic implications of countercyclical fiscal policy for France, Germany and the UK. The model incorporates real wage rigidity which is the particular market failure justifying policy...

We estimate a three-region (DE-REA-RoW) structural macroeconomic model, and we provide a counterfactual on how nominal exchange rate flexibility would have affected the German trade balance (TB) by simulating the shocks of the estimated model under a counterfactual flexible exchange rate regime....

Germany aims to phase out coal to achieve its 2030 climate target, for which a UK-style carbon price floor is considered. But this measure comes with risks related to the uncertainty about what price level is sufficient, and the waterbed effect arising from unilateral policy under the EU-ETS....
