Die notwendige ökologische Transformation aber auch darüberhinausgehend die zunehmenden Erwartungen, die Gesellschaft und Politik an die Wirtschaft stellen, erfordern eine Prüfung des Wettbewerbsrechts und seiner Durchsetzung, insbesondere auch der dabei verwendeten (ökonomischen) Konzepte...

Agencies around the world are in the process of developing taxonomies and standards for sustainable (or ESG) investment products. A key assumption in our model is that of non-consequentialist private investors (households) who derive a "warm glow" decisional utility when purchasing an investment...

This paper examines optimal enviromental policy when external financing is costly for firms. We introduce emission externalities and industry equilibrium in the Holmström and Tirole (1997) model of corporate finance. While a cap-and-trading system optimally governs both firms' abatement...

We show how a brand manufacturer's control over retail prices can lead to efficiencies when consumers rely on prices as a signal of quality. For this we first show how higher prices can be associated with both higher quality perception as well as higher actual quality. We next identify a...

We analyze firms' competition to steer an advisor's recommendations through potentially non-linear incentives. Even when firms are symmetric, so that the overall size of compensation would not distort advice when incentives were linear, advice is biased when firms are allowed to make...

How should firms optimally choose prices and promotional strategies and how should they position their products when consumers are "relative thinkers"? We provide answers in a model that extends the seminal contributions of Varian (1980) and Narasimhan (1988) and derive both managerial...

Embedding consumer experimentation with a product or service into a market environment, we find that unregulated contracts induce too few returns or cancella tions, as they do not internalize a pecuniary externality on other firms in the market. Forcing firms to let consumers learn longer by...

Arguably the most widely used techniques for estimating price overcharges from competition law infringements are the dummy variable and the forecasting approaches using linear regression analysis. While rarely used in practice, in this note we make use of the fully interacted dummy variable...

We model negotiations over patent royalties in the shadow of litigation through a Nash-in-Nash approach, where outside options, triggered in case of disagreement, are derived from a subsequent game of litigation. The outcome of litigation depends both on "hard determinants", such as relative...

Die Vorlage von in der Regel unterschiedlicher ökonometrischer Evidenz durch die verschiedenen Parteien birgt die Gefahr, dass diese vor Gericht ohne weitere Analyse als widersprüchlich erachtet und damit ggf. sogar gänzlich ignoriert werden. Mittels des Konzepts der "severity" oder "Schwere"...
