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...

In this paper, we present a more simple and independent proof of Reny's theorem (1998), on the existence of a Nash equilibrium in discontinue game, with a better-reply secure game in a Hausdorff topological vector space stronger than Reny's one. We will get the equivalence if the payoff function...

Candidate countries of central and eastern Europe (CEECs) are suppose to join the EU in 2004, June, which imply that they will face important challenges in the conduct of macroeconomic policy, in order to be able to enter the ERM-II system and eventually enter the EMU (European Monetary Union)....

A robust feature of the corporate growth process is the exponential distribution of firm growth rates. This striking empirical regularity has been found to hold for a number of different datasets and at different levels of aggregation. In this paper, we propose a simple theoretical model capable...

This paper deals with a multiobjective programming problem involving both equality constraints in infinite dimensional spaces. It is shown that some constraint qualifications together with a condition of interior points are sufficient conditions for the invexity of constraint maps with respect...

This paper gives estimates of sectoral markup trends over the last three decades. It concludes with a slight increase of price-cost margins overall, contrary to the generally expected effect of increased competition. More strikingly, it establishes a clear pattern of markup convergence across...

This paper raises the question of the dynamic effects of public spending in jobs on labor market performance. We use a dynamic matching model and study how public jobs creation affects endogenous workers' decisions to move on the labor market and private-sector firms' job creation and...

In this paper, we ask three questions about reference-dependent preferences (RDP) : to what extent can they be said to be irrational ? What is the mechanism that underlies reference dependence? How to design welfare improving policies when preferences are reference-dependent? As to the first...

In this paper, we study starting point bias in double-bounded contingent valuation surveys. This phenomenon arises in applications that use multiple valuation questions. Indeed, response to follow-up valuation questions may be influenced by the bid proposed in the initial valuation question....

Studies of the stability of international environmental agreements (IEAs) assumed a benevolent government who maximizes social welfare. The aim of our paper is to develop a theoretical framework in which the Government’s decisions are influenced by green and producer lobbies. To this end, we...
