We examine the interplay of endogenous vertical integration and costreducing downstream investment in successive oligopoly. We start from a linear Cournot model to motivate our more general reducedform framework. For this general framework, we establish the following main results: First,...

Merger value is frequently evaluated in single market contexts without considering possible gains stemming from firms' multimarket presence. This study concentrates on the question through which channels, and of which magnitude, mergers among multimarket firms create incremental value. We...

We analyze differences in performance between private companies (PCs) and state owned enterprises (SOEs), with an emphasis on the effects of market structure. We use a comprehensive panel covering all registered companies during the 1990s in Norway, a country where SOEs play an important role in...

Firms in traditional markets often compete in output à la Cournot. In this paper, we consider Cournot competition between platforms in a two-sided market. We find that the markup and markdown terms are distorted toward zero for greater levels of platform competition and for greater levels of...

We examine the interplay of endogenous vertical integration and cost-reducing downstream investment in successive oligopoly. We start from a linear Cournot model to motivate our more general reduced-form framework. For this general framework, we establish the following main results: First,...

We challenge the dichotomy of network effects and highlight that they are not an exogenous characteristic of networks, but endogenous to the decisions of network users. When users choose which activities to perform in a network, multi-activity users transform indirect into direct network...

We examine the relationship between management turnover and product market structure in a sample of U.S. newspapers from 50 large cities over the 1950-1993 time period. Examining 6 key managerial positions representing 18,849 observation-years, we find evidence of significantly higher rates of...

Using a panel data set of 361 German corporations for the period 1991-1996 we test the hypothesis that firms with more efficient governance structures have higher profitabilities. To determine efficiency we compare firms with respect to ownership concentration, the identity of owners, capital...

Although there has been an intensive debate on the relative merits of different sys-tems of corporate governance, empirical evidence on the link between corporate governance andfirm performance almost exclusively refers to the market-oriented Anglo-Saxon system. This papertherefore investigates...
