Weekly sales of creative goods – like music records, movies or books – usually peak shortly after release and then decline quickly. In many cases, however, they follow a hump-shaped pattern where sales increase for some time. A popular explanation for this phenomenon is word of mouth among a population of heterogeneous buyers, but previous studies typically(More)
This study analyses the relationship between entry regulation and infrastructure investment in the telecommunication sector. The empirical analysis we conduct is based on a comprehensive data set covering 180 fixed-line and mobile operators in 25 European countries over 10 years and employs a newly created indicator measuring regulatory intensity in the(More)
Antitrust policy involves not just the regulation of anti-competitive behavior, but also an important deterrence effect. Neither scholars nor policymakers have fully researched the deterrence effects of merger policy tools, as they have been unable to empirically measure these effects. We consider the ability of different antitrust actions – Prohibitions,(More)
In media markets, products are highly differentiated but prices are often bunched at apparent focal points. I use a comprehensive cross-section data set on the German book market to assess whether such focal points are a result of upstream coordination and whether the option to impose resale price maintenance (RPM) played a facilitating role. Therewith, I(More)
Investigating the link between ISO 9000 standards and bilateral exports, this paper contributes to the literature on standardization and international trade. A debate exists as to how ISO 9000 impacts trade. First, it has been argued that ISO 9000 is a " common language " that lowers information asymmetries between firms, thus allowing more efficient(More)
The gender pay gap under central planning and its changes in the course of transition have only lately attracted the attention of researchers. Only few papers focused on comparison between two economic regimes, pre and post reform, having reported narrowing gap for all East European countries. This paper adds more detailed study of timing of the gap changes(More)
The effects of ISO 9000 diffusion on trade and FDI have gone understudied. We employ panel data reported by OECD nations over the 1995-2002 period to estimate the impact of ISO adoptions on country-pair economic relations. We find ISO diffusion to have no effect in developed nations, but to positively pull FDI (i.e., enhancing inward FDI) and positively(More)
This paper provides empirical evidence on the extent of network effects and compatibility between networks in mobile telecommunications. We specify a structural model of demand for mobile telephone service, which allows us to identify the parameters of interest from the S-shape of mobile service diffusion. The network effects are measured by the dependence(More)
