We analyze a class of "large group" Chamberlinian monopolistic competition models using multiplicatively quasi-separable (MQS) and additively quasi-separable (AQS) functions. We first prove that the MQS and AQS functions are equivalent to the "constant relative risk aversion" (CRRA) and...

We consider a simple general equilibrium model with imperfect competition. Firms are price taker in the input market and compete à la Cournot in some or all of the product markets (their technology displays constant returns to scale). We show that an increase in the number of firms does not...

The paper seeks to integrate the theoretical developments in the field of imperfect competition and monopoly, and operation of the firm in such conditions, with the theories of income distribution, particularly among the macroeconomic aggregates of capital and labor. And formulating a working...

In this paper, we develop a framework for the formulation, analysis, and computation of solutions to spatial network problems in which the firms are multicriteria decision-makers and the consumers are as well. In particular, the firms, which are involved in the production of a homogeneous...

Trade policy has well documented effects on trade volumes. Reaching beyond volumes, I explore the impact of European emerging economies' recent institutional trade liberalisation on extensive (i.e., the set of imported goods) versus intensive import margins (volumes per imported good) with...

Although trade liberalisation has been linked econometrically and through casual empiricism to large income increases, attempts to quantify its impact in static simulation models have shown small estimated gains. This paper shows that when the endogenous dynamic effects of trade liberalisation...

The interaction between trade liberalisation, product and process innovation, and relative skill demand is analysed in a model of international oligopoly. Lower trading barriers increase the degree of foreign competition. The competing enterprises respond by investing more aggres- sively in...
