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 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...
