This paper examines if international trade can reduce total welfare in an international oligopoly with differentiated goods. We show that welfare is a U-shaped function in the transport cost as long as trade occurs in equilibrium. With a Cournot duopoly trade can reduce welfare compared to...

We use a dynamic oligopoly model of entry and exit to evaluate how entry regulations affect profitability and market structure in retail. The model incorporates demand and store-level heterogeneity. Based on unique data for all retail food stores in Sweden, we find that the average entry costs...

The capacity of the transmission network determines the extent of integration of a multinational energy market. Cross-border externalities render coordination of network maintenance and investments across countries valuable. Is it then optimal to collect powers in the hands of a single...

This paper analyzes a three-stage optimization problem in which a firm chooses (i) its technology, by deciding on a level of R&D, (ii) whether this technology is to be used in a domestic or in a foreign plant and (iii) the quantity produced and sold on the market. If technology transfer costs...

This paper proposes an approach for predicting the pattern of mergers when different mergers are feasible. It generalizes the traditional IO approach, employing ideas on coalition-formation from cooperative game theory. The model suggests that in concentrated markets, mergers are conductive to...

This paper studies privatization policy in an international oligopoly. The argument that equal treatment of foreign investors will be detrimental to domestic welfare by shifting profits from domestic to foreign firms is shown to be less relevant in privatization auctions than in greenfield FDI...

This paper evaluates the welfare consequences of the failing firm doctrine in the EU and US merger laws. I combine an oligopoly model with an "endogenous valuations" auction model. Thereby, I take into account that, in an oligopoly, a firm's willingness to pay for the assets depends on the...

In a framework where mergers are mutually excluding, I show that firms pursue anti- rather than (alternative) pro-competitive mergers. Potential outsiders to anti-competitive mergers refrain from pursuing pro-competitive mergers if the positive externalities from anti-competitive mergers are...
