We present a two-firm model of predation under complete information, based on different discount factors, and integrate it with a model of collusion. Competition, collusion and predation are seen as alternative strategies. The basic conclusions are that there is predation when one firm has a...

A structural model of entry and fiscal policy is presented. It shows that taxation of variable production costs can increase product prices, lower competition, and reduce the availability of new products in small markets. The model?s test is based on a unique nationwide fiscal experiment. We...

This paper discusses a simultaneous market entry game between two firms with different fixed costs. This case is a typical application of mixed strategy equilibria. Conventional wisdom would suggest that the low-cost firm is more likely to enter the market. This presumption is wrong. Instead,...

This paper develops a model of successive oligopolies with endogenous market entry, allowing for varying degrees of product differentiation and entry costs in both markets. Our analysis shows that the downstream conditions dominate the overall profitability of the two-tier structure while the...

This paper models competition between two firms, which provide broadband Internet access in regional markets with different population densities. The firms, an incumbent and an entrant, differ in two ways. First, consumers bear costs when switching to the entrant. Second, the entrant faces a...

We show in a simple model of entry with sunk cost, that a regulator prefers limiting the output, orcapacity, of the incumbent firm rather than imposing a “Minimum Quality Standard” in order tohelp the entrant to provide high quality. As a by-product, our analysis makes a contribution to...

This paper investigates the effects of mergers, entry, and exit in retail markets when input prices are negotiated. Results are derived from a model of bilateral Nash-bargaining between manufacturers and retailers which allows for general forms of demand and retail competition. Whether...

We consider a software vendor first selling a monopoly platform and then an application running on this platform. He may face competition by an entrant in the applications market. The platform monopolist can benefit from competition for three reasons. First, his profits from the platform...
