We analyse a disregarded environmental policy instrument: a switch in government expenditure away from energy (or other natural resources) and toward a composite good which includes energy-saving expenditure. We first develop two variants of an analytical general equilibrium model. A composite...

The aim of this short article is to build a model in order to take into account capital scrapping (or bankruptcies) in an income distribution and growth model. The reason to introduce capital scrapping results from the intuition of some inconsistencies between theoretical predictions and...

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...

In this paper, financial infrastructures increase the efficiency of the banking sector: they decrease the market power (due to horizontal differentiation) of the financial intermediaries, lower the cost of capital, increase the number of depositors and the amount of intermediated savings,...
