While liberalization in energy markets has been a widely successful process all over the world, incumbents often still hold a dominant position. Thus, electricity wholesale markets are subject to market surveillance. Nevertheless, consolidated findings on abusive practices of market power and...

We investigate the effect of market structure on market performance in the market for consumer electronics. This research is novel, because we exploit product life cycle information to build an instrumental variable for the number of firms in a market, a variable which hitherto had to be treated...

This paper analyses the effects of minimum wages on competition in the German roofing sector. The case is particularly interesting since this sector is faced with a uniform minimum wage despite significant regional disparities in productivity and wages. As a control industry we take the plumbing...

The paper investigates the construction of a low cost airline network by analyzing JetBlue Airways' entry decisions into nonstop domestic U.S. airport-pair markets between 2000 and 2009.

In German electricity submarkets for residential customers standard contracts offered by former monopolists are the more costly option for customers who have not switched to an alternative contract yet. As most German households are served with this contract type we follow the Limit Pricing...

We investigate the effect of market structure on market performance in the market for consumer electronics.

We examine the scope and value of targeted advertising in the magazine industry. We use data on reader characteristics at individual media, in contrast to previous work that has needed to infer this information from aggregate data. Our results show a strong relationship between subscriber...

Basu (2006) argues that the prevalence of 99 cent prices in shops can be explained with rational consumers who disregard the rightmost digits of the price. This bounded rational behaviour leads to a Bertrand equilibrium with positive markups. We use data from an Austrian price comparison site...

The present paper first discusses theoretically the different incentives of manager- versus owner-controlled firms for investment into innovative activity. In addition, the role of debt financing is analyzed. Subsequently the results from an empirical study on the determinants of innovative...
