Since June 15, 2017, mobile network operators in the European Economic Area may not impose surcharges for making telephone calls, sending text messages, or using data services in other EEA countries. The regulation was designed to create a digital domestic market without adversely affecting consumers. The regulation raises the expectation of changes in mobile network operators’ tariff structures. ...

This paper uses information on the legal status upon arrival to study long-term labor market effects, whereas selection and potential outmigration are taken into account by a large set of methods. I find that immigrants arrived with a job commitment in Germany achieve a longterm income advantage of 18.6% relative to other migrant groups, while language skills and ethnic networks can be excluded as ...
A common assumption in the optimal taxation literature is that the social planner maximizes a welfarist social welfare function with weights decreasing with income. However, high transfer withdrawal rates in many countries imply very low weights for the working poor in practice. We reconcile this puzzle by generalizing the optimal taxation framework by Saez (2002) to allow for alternatives to welfarism. ...

At it latest Governor’s Council meeting in January 2019 it decided to remain on this track despite a sharp appreciation of the euro in the meanwhile. These steps were just two on a longer and potentially ...
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 demonstrates how a conditional nonparametric method, which allows ...
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 ...
Whether pro-social preferences identified in economic laboratories survive in natural market contexts is an important and contested issue. 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. German income tax statistics offer the unique possibility to go back as far as 1871 and produce series for eight German states ranging from heavily industrializing Prussia or Saxony to mostly agrarian Baden or Wurttemberg. Top income earners in Germany are mostly business ...
