Mainstream locus communis indicates that a more competitive product market leads to higher social welfare levels. Using a Conjectural Variation (CV) model, this research note analyzes the effects on welfare of different degrees of product market competition in a duopoly with differentiated...

The objective of this article is to measure the degree of competition among retail stores to sell a specific brand of a product. For this purpose, we estimate brand-specific demand equations along with first order conditions from stores' profit maximization. In stores' profit maximization, we...

In this paper, we construct dynamic models on the basis of constant conjectural variation. Duopolists with dynamic adjustment behavior of bounded rationality have been considered. Numerical simulation is used to illustrate the complexion of models. The existence of equilibrium points and their...

The present analysis is an application of the continuous time replicator dynamic to economics. Three types of problems are considered under conditions of a normalized constraint and non-negative constrains. The story of the following models is as follows. There are three or more corporations in...

This paper analyses the competitiveness of the mobile telecommunications industry across the European Union. A structural model of demand and supply has been estimated for annual data on 15 EU countries from 1998 to 2002. Estimates of country-specific conjectural variations allow us to compare...

Purpose – During the last two decades there have been significant policy changes in the banking system, primarily in the emerging market economies. These changes have impacted the competitive structure of banking. In India, since 1991, gradual reform measures have been initiated to improve...
