A general theoretical and empirical framework is developed for assessing the potential of a vertically integrated firm to foreclose downstream competitors. Using this framework a policymaker may also evaluate the empirical welfare effects from a vertically integrated firm raising rivals' costs....

In 2011, price peaks in retail gasoline prices caused public outrage and attracted the attention of German regulatory agencies. After having examined the market, competition authorities concluded that tacit collusion existed but could not easily be prosecuted under the given competition law. In...

Applicants for any given job are more or less suited to fill it, and the firm will select the best among them. Increasing the wage offer attracts more applicants and makes it possible to raise the hiring standard and improve the productivity of the staff. Wages that optimize on the trade-off...

This paper focuses on the legal monopoly for sporting bets in Germany. We analyze the pricing behavior of the monopolist ODDSET and find that typical pricing inefficiencies on betting markets are reinforced under the monopoly. This result in conjunction with the decreasing tax revenue may...

The number of studies published focusing on people’s preferences for green electricity has increased steadily, making it more and more difficult to identify key explanatory factors that determine people’s willingness-to-pay (WTP). Based on results of a meta-regression our results indicate...

Following a major earthquake off the Pacific coast of Japan, a tsunami disabled the power supply and cooling of three reactors in Fukushima, causing a major nuclear accident on 11 March 2011. Based on a quasi-experimental difference-in-differences approach we use panel data for 5,979 individuals...

The authors consider a symmetric model composed of two countries and a firm in each country. Firms produce the same good by means of a polluting technology which uses fossil energy. However, these firms can adopt a clean technology which uses a renewable energy having a lower unit cost....

The efficiency of the Pigouvian tax suggests that price-based regulation is the proper benchmark for efficient regulation. However, results due to Carlton and Loury (1980, 1986) question this; when harm depends on scale effects a pure Pigou tax is inefficient regulation in the long run. In this...

In this paper, we consider a non-cooperative and symmetric three-stage game model composed by two regulator-firm hierarchies. By means of adequate emission taxes, original and absorptive research and development (R&D) subsidies we prove that regulators can reach the non-cooperative social...
