Revenue cap regulation is often combined with systematic benchmarking to reveal the managerial inefficiencies when regulating natural monopolies. One example is the European energy sector, where benchmarking is based on actual cost data, which are influenced by managerial inefficiency as well as operational heterogeneity.

This paper experimentally investigates how concerns for social approval relate to intrinsic motivations to purchase ethically. Participants state their willingness-to-pay for both a fair trade and a conventional chocolate bar in private or publicly. A standard model of social image predicts that all participants increase their fair trade premium when facing an audience. We find that the premium is ...

We investigate how fairness in a laboratory experiment framed explicitly as a market exchange relates to preferences for fair trade products before and after the market experiment. We find that the willingness to buy at a higher price when higher wages are paid ...
This study provides new homogeneous series on top income shares in Germany from the early phase of industrialization until present.

This paper addresses some key issues around the emergence of nuclear power in the twentieth century and perspectives ...
I assert that air pollution from nitrogen oxides affects the productivity of employees in Mexican court hearings. This is the first article analyzing this connection and the first to disentangle work-breaks from the productivity of white-collar workers. I merge hourly pollution with granular hearing data under the assumption that the length of the hearing approximates productivity and identify causality ...
