We analyze Bertrand duopoly competition in markets with network effects and consumer switching costs. Depending on the ratio of switching costs to network effects, our model generates four different market patterns: monopolization and market sharing which can be either monotone or alternating. A...

We analyze market dynamics under Bertrand duopoly competition in industries with network effects and consumer switching costs. Consumers form installed bases, repeatedly buy the products, and differ with respect to their switching costs. Depending on the ratio of switching costs to network...

This paper investigates how the formation of larger buyers affects a supplier's profits and, by doing so, his incentives to undertake non-contractible activities. We first identify two channels of buyer power, which allows larger buyers to obtain discounts. We subsequently examine the effects of...

Considering a vertical structure with perfectly competitive upstream firms that deliver a homogenous good to a differentiated retail duopoly, we show that upstream fixed costs may help to monopolize the downstream market. We find that downstream prices increase in upstream firms' fixed costs...

We present a model of takeover where the target optimally sets its reserve price. Under relatively standard symmetry restrictions, we obtain a unique equilibrium. The probability of takeover is only a function of the number of firms and of the insiders' share of total industry gains due to the...

This paper examines how different unionisation structures affect firms' innovation incentives and industry employment. We distinguish three modes of unionisation with increasing degree of centralisation: (1) 'Decentralisation' where wages are determined independently at the firm-level, (2)...

We analyze duopoly Bertrand competition under network effects. We consider both incompatible and compatible products. Our main result is that network effects create a fundamental conflict between the maximization of social welfare and consumer surplus whenever products are incompatible. While...

We present a model with firms selling (homogeneous) products in two imperfectly segmented markets (a high-demand and a low-demand market). Buyers are mobile but restricted by transportation costs, so that imperfect arbitrage occurs when prices differ in both markets. We show that equilibria are...
