By developing a linear model in a two-country framework of international price competition, we show how the degree of product differentiation and the cross-country distribution of private firms affect the strategic privatization choices made by governments concerned with their own country's...

We enquiry about the effects of first and second order stochastic dominance shifts of the distribution of the consumers’ willingness to pay, within the standard model of a market with network externalities and hump-shaped demand curve. This issue is analyzed in the polar cases of perfect...

The paper shows that the co-movements of optimal price and output in a monopolistic market can be a case of spurious correlation, price and quantity variations being affect by the degree of uncertainty in the consumers' incomes. The pattern of price and quantity changes depends on the shape of...

This paper contrasts the descriptive and normative properties of the New Keynesian general equilibrium models with those of other Keynesian paradigms, such as the neoclassical sintesi and the post Keynesian ones. We argue that the co-ordination failures, which are pivotal within the New...

The paper proves the existence of a subgame perfect Nash equilibrium in a vertically differentiated duopoly with uncovered market, for a large set of symmetric and asymmetric distributions of consumers, including, among others, all logconcave distributions. The proof relies on the 'income share...

We describe a spatial duopoly in a Hotelling model with quadratic transportation costs where consumers are distributed according to a symmetric density whose degree of concentration is variable. By solving the two-stage game in prices and locations as a function of the concentration index, we...

The paper investigates both quantity and price oligopoly games in markets with a variable number of managerial and entrepreneurial firms which defines market structure. Following Vickers (Economic Journal, 1985) which establishes an equivalence between the equilibrium under unilateral delegation...

This paper reconsiders the literature on the irrelevance of privatization in mixed markets, addressing both quantity and price competition in a duopoly with differentiated products. By allowing for partially privatizing a state-controlled firm, we explore competition under different timings of...

We reconsider the endogenous choice of delegation to a manager by two down-stream firms in both a Cournot and a Bertrand vertical market with network effects. An upstream monopolist charges a two-part tariff for a crucial input. By applying the Nash solution in a centralized bargaining, we show...

It is widely believed that vertical integration in an environment without foreclosure, or more generally without any mechanism that restricts competition among firms, raises the welfare of consumers. In this paper we show that this can be overturned in a standard setting. We consider a vertical...
