This paper studies welfare effects of uniform production subsidies in oligopoly markets, comparing cases of asymmetric and symmnetric costs. Cost asymmetry reduces the impact if the demand function is concave and magnifies the impact if demand is convex.

This article studies welfare effects of uniform production subsidies in oligopoly markets, comparing cases of symmetric and asymmetric costs. Cost asymmetry reduces the welfare impact relative to the symmetric-cost case if the demand function is concave and magnifies the impact if demand is...

Trials of new oncology treatments often involve a crossover element in their design that allows patients receiving the control treatment to crossover to receive the experimental treatment at disease progression or when sufficient evidence about the efficacy of the new treatment is achieved....

This paper studies the effect of production subsidies used as strategic instruments by two rivalling countries whose firms differ in production efficiency. In particular, it examines the welfare effects of a uniform subsidy reduction from the Cournot-Nash equilibrium under different assumptions...

Many oligopoly theories predict that there will be a positive correlation between market size and the equilibrium number of firms, and some also imply that competition is more intense in larger markets. We test these predictions with a sample of 535 driving schools in 249 markets. With an...

We study the product turnover in an industry and, in particular, the survival of new products. The data set consists of monthly sales of all products sold in the Swedish beer market over the time period of 1989-1995. The death rates of newly introduced products are high - out of 199 products an...

Many oligopoly theories predict a positive correlation between market size and the equilibrium number of firms and some also imply that competition is more intense in larger markets. The authors test these predictions on a sample of driving schools in 250 Swedish regional markets by estimating...

This paper studies competition in small, concentrated and inter- related markets. Our data set consists of price information fron 543 driving schools in 250 local markets in sweden, which gives a large sample to test hypotheses on how market structure influences competition. The results show...
