This study investigates how transportation costs and environmental damage affect social welfare and the optimal degree of nationalization by assuming asymmetric mixed oligopoly markets. It assumes that both transportation costs and environmental damage are incurred when products are transported...

This paper investigates the preference for the Stackelberg leader/follower roles in a mixed duopoly, where a welfare-maximizing public firm competes with a profit-maximizing private firm. In contrast to the well known relationship in a private duopoly, we demonstrate that if a firm's reaction...

We discuss optimal privatization policies in mixed oligopolies in which a public firm is the Stackelberg follower (private leadership). We find that under constant marginal cost, the optimal degree of privatization is zero. When the marginal cost is increasing, however, the optimal degree is...

We investigate a Cournot model with strategic R&D investments wherein efficient low-cost firms compete against less efficient high-cost firms. We find that an increase in the number of high-cost firms can stimulate R&D by the low-cost firms, while it always reduces R&D by the high-cost firms....

We provide a simple theoretical model to explain the mechanism whereby privatization of international airports can improve welfare. The model consists of a downstream (airline) duopoly with two inputs landings at two airports) and two types of consumers. The airline companies compete...

We investigate the effects of restricting locations of firms into Hotelling duopoly models. In the standard location-price models, the equilibrium distance between firms is too large from the viewpoint of consumer welfare. Thus, restricting locations of firms and reducing the distance between...
