Random utility models are widely used to study consumer choice. The vast majority of applications assume utility is linear in consumption of the outside good, which imposes that total expenditure on the subset of goods of interest does not affect demand for inside goods and restricts demand...

A comprehensive, microdata-based analysis of the German tax system's distributional effects in 2015 shows that the total tax burden from direct and indirect taxes is slightly progressive on higher income, but regressive in the lower deciles. Income and corporate taxes are distinctly progressive....

Eine umfassende mikrodatenbasierte Analyse zu den Verteilungswirkungen des deutschen Steuersystems im Jahr 2015 zeigt, dass die gesamte Steuerbelastung aus direkten und indirekten Steuern bei steigenden Einkommen nur moderat progressiv verläuft und in den unteren Dezilen regressiv wirkt. Zwar...

We study the strategic utilization of storage in imperfect electricity markets. We apply a game-theoretic Cournot model to the German power market and analyze different counterfactual and realistic cases of pumped hydro storage. Our main finding is that both storage utilization and...

We use a game-theoretic model to analyze the impacts of a hypothetical fleet of plug-in electric vehicles on the imperfectly competitive German electricity market. Electric vehicles bring both additional demand and additional storage capacity to the market. We determine the effects on prices,...

European postal markets are to be completely liberalized by the end of 2012 at the latest. At the same time national regulatory frameworks are being adapted to the new requirements. The extent to which the present monopoly suppliers will in future (continue to) be obliged to grant their...

The upcoming full liberalization of postal service markets under the European regulatory framework offers the chance to further increase regulatory efficiency. Obstacles to competition and barriers to market entry should be systematically removed, and existing obligations for all companies...
