Mixed oligopoly,foreign penetration,and environmental taxes

This paper examines the impact of foreign penetration on the public firm in a mixed oligopolistic market. Through the establishment of a mixed double oligopoly market, this paper analyzes how the share of foreign investment affects the environmental policy, the pollutant emission, and the social welfare under the condition of the state tax. The results show that: first, the introduction of foreign investment has some crowding-out effects on the social level of output. Second, the entry of foreign investment increases the profit of the public firm by a large margin, and the maximum profit of the private firm has been reduced. Third, the increase of foreign investment in public firm does not necessarily improve the environment.

A Differential Oligopoly Game Under Price Competition

A dynamic actual demand function was used to portray a market environment for fast moving consumer goods and to establish oligopoly differential games under price competition. We confirmed the stable point in n-player price competition as the saddle point of differential games, and acquired the optimal price and demand at equilibrium. Analysis on optimal price and demand shows that, to obtain more profits, a manufacturer should control costs, rapidly occupy the market, and improve product uniqueness.

A Model of Competition with Environmental Taxes and Regulation Under Conditions of Oligopoly

The Cournot static game with complete information is reviewed. A model of competition with environmental taxes under conditions of oligopoly is built based on the Cournot game, and some helpful conclusions are drawn from the model. A game model with regulation of government is also established. Finally the optimization problem of market structure is discussed.

A Game Theoretic Approach for Hierarchical Caching Resource Sharing in 5G Networks with Virtualization

Caching and virtualization have been considered as the promising techniques in 5G Networks. In 5G networks with virtualization, the caching resources deployed by infrastructure providers (InPs) can be abstracted into isolated slices and transparently shared by mobile virtual network operators (MVNOs). In this case, one of the most important issues is how the MVNOs to share the caching resource. To solve this issue, different from previous works, a hierarchical caching architecture that core network and radio access network (RAN) have the caching capability in 5G networks with virtualization is first considered in this paper. Then, we study the problem of hierarchical caching resource sharing for MVNOs, and a competitive game to maximize their expectation revenue based on the oligopoly market model is formulated. As it is a hard problem to find the optimal solution in the hierarchical caching resource sharing problem, we decompose the optimization problem into two independent caching resource sharing problems in RAN and core network, respectively. Then the local optimal solutions are solved and the global Nash equilibrium solution is achieved. Finally, simulation results are illustrated to demonstrate the performance of the proposed scheme.

ON ADVANTAGE-COMPLEMENTARY MERGER:INCENTIVES AND RESULTS

This paper studied the change of the firm’s profit and social welfare after merger in the case of oligopoly and inhomogeneous products. By the hypothesis of an uncooperative perfect information static game model, the characteristics of market and products needed for the firm to improve its profit through merger were discussed under Cournot oligopoly model and Bertrand oligopoly model. To raise the firm’s profit can be well described as the incentive of advantage complementary merger. The change of social welfare influenced by the merger was also discussed. From the view of maximizing global social welfare, some advice was also given to regulate this type of merger.

Market Analysis to the Steel Industry: Evidence from Egypt

This case study is guidance for the market forces in one of the important industries.This study is prepared to analyze the market forces affecting the flat steel industry during the period from 2013 to 2017 in Egypt.The steel market in Egypt is a very wide market with many companies and a wide variety of products.The study will provide insight on the supply,demand,and elasticity of flat steel produced by Al-Ezz Dekheila Steel Company which is one of the biggest producers of flat steel in the Middle East.Finally insight for this industry for the future business opportunities.

Static Aspect of Heterogeneous Competition in Duopoly

The study gives a comparison between price policy and quantity policy in duopoly producing differentiated goods with different production costs and indicates which is more beneficial. Further, it is investigated that in a non-linear duopoly with differentiated goods and two different policies, firms may earn more profit if they choose a quantity policy in a stable economy when the marginal production cost of both the firms is the same. If the production cost of both firms is different, then the price policy is better only when the firm is efficient.

Kreps&Scheinkman with Product Differentiation

Kreps and Scheinkman (1983)'s celebrated result is that in a two-stage model of a market with homogeneous products in which firms noncooperatively pick capacities in the first stage and set prices in the second stage, the equilibrium outcome is that of a one-shot Cournot game. This note derives capacity best response functions for the first stage and extends the Kreps and Scheinkman result to the case of differentiated products.
