    Opis:
    We consider Cournot oligopoly with differentiated product. We develop respective sufficient conditions on the inverse demand and cost function that make the oligopoly a game of strategic substitutes when goods are substitutes and a game of strategic complementarities when goods are complements. The scope of this result is illustrated by examples. JEL classification: C72, L10, L13.

    Opis:
    Research background: This paper extends the early papers by Brander (1981) and Brander and Krugman (1983) who used a simple partial equilibrium Cournot duopoly to a full general equilibrium setting. The explanations of intra-industry trade can be based either on oligopolistic reciprocal dumping idea (Brander, 1981) or product differentiation (Dixit and Norman, 1980; Krugman, 1979, 1980, 1981; Lancaster, 1980; Helpman, 1981). In this paper we combine both explanations in a unified general equilibrium model. Purpose of the article: We develop a two-sector, one-factor general equilibrium model, in which the first sector produces a differentiated good under monopolistic competition and the second sector produces a homogenous good under Cournot oligopolistic competition. In this paper, we study how competition between domestic and foreign firms resulting from trade liberalization affects intra-industry trade in both sectors. Methods: The paper develops a two-sector model based on several assumptions. Consumers have a two-tier utility function of the Cobb-Douglas-Spence-Dixit-Stiglitz form. Firms operate in two sectors and produce goods under increasing returns to scale resulting from the existence of fixed costs. One sector produces homogenous good under Cournot competition, and the second one produces a differentiated product in under Chamberlinian monopolistic competition. Free entry is assumed in both sectors. Labor is assumed to be the only factor of production with perfect mobility and full employment. Findings & Value added: In contrast to previous papers, our study is based on a full general equilibrium Cournot oligopoly framework with many firms. Moreover, we endogenize the number of firms and study the resulting trading equilibria. Therefore, this paper can be regarded as the extension and unification of the early papers by Brander (1981), Brander and Krugman (1983) and Krugman (1979, 1980).

    Opis:
    The main goal of this article is to contribute to the theoretical analysis of international trade under imperfect competition using the Cournot oligopoly model with heterogeneous firms. In particular, our objective is to provide some insights into the role of cost asymmetry in studying the effects of trade liberalisation in the Cournot oligopoly framework. In order to introduce firm heterogeneity into the oligopoly model we use the generalised Cournot framework with asymmetric firms that differ in terms of their productivity, levels of output and market shares. We show that trade liberalisation leads to the elimination of less productive firms and results in lower equilibrium prices, higher sales per firm and lower markups in the industry.

    Opis:
    The paper presents a model describing the behavior of participants of the oligopolistic market. Economic model of the oligopoly – a generalized Cournot-Puu model is constructed. Notion of Cournot equilibrium is introduced. Study on the stability of the equilibrium point of the constructed model is described. As an example, the model of duopoly is considered in detail.
