Price Symmetry in a Duopoly with Congestion

چکیده

We show that in a duopoly operating in a congested market, with a general congestion function and an arbitrary distribution of consumer disutility for congestion, there cannot exist an asymmetric Nash equilibrium. We also show that whenever an equilibrium does exist it is unique. Closed form expressions for the symmetric equilibrium prices and profits are provided. JEL Classification Numbers: C72, D43.

Retailers sell substitute products in the framework of the classical economic order quantity (EOQ) model with linear demand function. The market potential and competitor price are considered to be the bifurcation parameters of retailers. Levels of the barriers to market penetration depending...

Centralized Supply Chain Network Ddesign: Monopoly, Duopoly, and Ooligopoly Competitions under Uncertainty

This paper presents a competitive supply chain network design problem in which one, two, or three supply chains are planning to enter the price-dependent markets simultaneously in uncertain environments and decide to set the prices and shape their networks. The chains produce competitive products either identical or highly substitutable. Fuzzy multi-level mixed integer programming is used to mo...

A game theory approach to the sawnwood and pulpwood markets in the north of Iran

Duopoly game theory is applied to the wood industrial markets (sawnwood and pulpwood markets) in the North of Iran. The Nash equilibrium and the dynamic properties of the system based on marginal adjustments are determined. The probability that the Nash equilibrium will be reached is almost zero. The dynamical properties of sawnwood and pulpwood prices derived via the duopoly game model are fou...

Social Welfare under Quantity Competition and Price Competition in a Mixed Duopoly with Network Effects: An Analysis

In their recent work, Matsumura and Ogawa (2012) showed that in the context of a mixed duopoly, equilibrium social welfare is higher in price-setting competition than in quantity-setting competition. We found that when the strength of network effects is sufficiently high, the above result is totally reversed; thus, in a mixed duopoly, the presence of network effects weakens the superiority of p...
