We analyse the influence of wage bargaining on the firm´s research incentive. In a duopoly setting, firms invest resources into a Reinganum-type patent race. The wage is bargained for with a union. Besides the holdup and the strategic effect, which have been analysed before, we are able to...

Banks play a central role in financing and monitoring firms in transition economies. We study how bank competition affects the efficiency of the credit allocation, the monitoring of firms, and the firms' restructuring effort. In our model, banks compete to finance an investment project with...

A safe and risky seller serve a market. While the expensive safe seller can solve the problems of all consumers, the cheap risky seller can help a consumer only with a certain probability. The risky seller's success probabilities are distributed across consumers; by the choice of her quality the...

The literature has established two kinds of entry bias in imperfectly competitive markets. First, free entry may lead to excessive entry relative to the socially optimal level. Second, free entry may lead to the wrong technology (type of firm) in the market compared to the socially optimal...

We revisit the comparison between Bertrand and Cournot competition in a symmetric differentiated oligopoly where each firm maximizes a weighted average of its own profit and welfare. Under very general specifications, Bertrand competition yields higher prices and profits, and lower quantities,...

Based on a Hotelling-type model, this paper analyzes a differential game where two firms engage in quality-enhancing research and development (R&D). The analysis is formulated in terms of open-loop and feedback solutions. We find that the open-loop stationary levels of R&D and quality are...

This paper studies welfare consequences of consumer-side market transparency with endogenous entry of firms. Different from most studies, we consider the unique symmetric entry equilibrium, which is in mixed strategies. We identify two effects of market transparency on welfare: a competition...

We examine the effect of uncertainty on horizontal mergers, considering that firms must decide whether to merge before observing the realized cost of the merged firm. The existing literature clarifies that merging firms facing cost uncertainty decide to merge if expected efficiency gains or...

We use a search model to study how the outside market affects the inside market. Consumers look for price and match information through either a costly sequential search or a monopoly platform, which chooses the number of inside firms. Our analysis finds an equilibrium where each consumer visits...

We examine both quantity and price competition in a mixed oligopoly. In a market in which the adoption of commitment strategies enables the public firm or a government to achieve welfare gains, profits of both the public and the private firms turn out to be higher under Cournot than Bertrand...
