The paper proves that monopolistic price discrimination increases output under conditions of constant demand elasticity. The demonstration is simpler than that of Formby, Layson and Smith (1983)

We discuss the effects of bundling two goods offered by two symmetric firms. This situation requires the use of some sharing rule for the profits from the sales of the bundle. We show that the choice of this rule may have substantial effects on prices and profits – even if the possible...

One important issue in firms' governance is how to incentives so that activity centres can become more efficient. In this paper, we first introduce an agency contract where the salary of the manager of an activity centre that produces an intermediate product is dependent of its performance....

White (1996), Poyago-Theotoky (2001) and Myles (2002) prove that in the mixed oligopoly the optimal subsidy, equilibrium output level, all firms' profits and social welfare are identical irrespective of whether the public firm maximizes welfare or profit and moves simultaneously with private...

We are the first to confirm that sufficient cost convexity in a Stackelberg model generates profitable mergers between two leaders and between two followers. Moreover, the degree of convexity required for leaders to merge is generally far smaller than that required for followers. Most...

The aim of this work is to test the Gibrat's Law hypothesis for Brazilian firms. Gibrat''s Law establishes that firm growth is a random walk, it means that the probability of a given proportionale change in size during a specified period is the same for all firms in a given industry. This work...
