This article explores the economic conditions for the viability of organic farming in a context of imperfect competition. While most research dealing with this issue has adopted an empirical approach, we propose a theoretical foundation. Farmers have a choice between two technologies, the...

International trade has been expected to reduce the gender wage gap by increasing competition and thus reducing the rents that allow employers to discriminate. However, some empirical assessments find an opposite effect. We provide an explanation for the puzzling result that trade openness...

Abstract This article studies a new class of models which synthesize the two traditions of general equilibrium with nonclearing markets and imperfect competition on the one hand, and dynamic stochastic general equilibrium (DSGE) models on the other hand. This line of models has become a central...

This paper explores the consequences of imperfect competition on capital accumulation. The framework is an OLG growth model with altruistic agents. Two types of long run equilibria exist : egoistic or altruistic. We assume both competitive and non-competitive firms exist, the latter being...

This paper presents an overlapping generations model with altruistic consumers, in which pension funds, by holding a signi...cant share of capital assets, produce non competitive behavior. We study the consequences of such behavior on capital accumulation and welfare in the long run when...

Traditional trade models ignoring the dimension of product quality generally lead to excessively low trade price elasticities. In this paper, we show that higher estimated trade price elasticities, more in conformity with theory, can be obtained by controlling product quality in trade equations....

We analyze the relationship between imperfect competition and capital accumulation in a dual economy, with traditional and modern sectors and two types of agents (workers and capitalists). Workers allocate their time endowment between the two sectors. Capitalistsaccumulate wealth in the modern...

In macroeconomics, economists introduce most frequently imperfect competition on product markets using the Dixit and Stiglitz (1977) monopolistic competition model. However, by assumption, this framework ignores one important feature of imperfect competition: strategic interactions between...

Previous studies have emphasized that Roeger's methodology generates too high markups. This feature is confirmed on the basis of the unrealistically low capital shares implied by the estimates herein. Theoretically, it is shown that the normalization choice, the slow adjustment of capital and...

We analyze the relationship between imperfect competition and capital accumulation in a dual economy, with traditional and modern sectors and two types of agents (workers and capitalists). Workers allocate their time endowment between the two sectors. Capitalists accumulate wealth in the modern...
