This paper empirically explores the relationship between firms' market behavior and their lobbying activities in a regulated market. In particular, we investigate whether the amount of contributions offered by cellular service providers to fund the campaigns of political parties affected market...

The standard model by Laffont, Rey and Tirole (1998) treats termination fees as an instrument to increase market power in a one-shot game of horizontal product differentiation. We offer an alternative view in an infinitely repeated Bertrand competition. We focus on symmetrical call-ing patterns...

How does the choice to regulate a market take place? And how does regulation influence market outcome? We argue that to explicitly model the simultaneity between these two issues makes a qualitative difference in the analysis of the role of regulation, and empirically test our model in the U.S....

This paper argues that the study of policy incidence in industrial organization needs to take the endogeneity of government into account. The point is made by investigating whether political considerations are important in terms of understanding the causes and effects of deregulation using data...

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...

This paper develops a political-economy model of price regulation. Firms' lobbying activity for a given regulatory status might generate a simultaneity problem between the effects and the determinants of regulatory decisions. We explicitly model this two way causality, and empirically test our...

Abstract In markets with competing interconnected networks like mobile telecommunication markets investments affect the investor’s and also any competitors’ profits. In a theoretical model it is shown that cost-reducing investments reduce the investor’s termination rates and increase...

I develop a structural demand model for mobile telephone service, which facilitates the identification of network effects and compatibility between networks. Network effects are measured by the dependence of consumer willingness to pay on the installed base of subscribers. Compatibility is...
