We develop a model in which agents choose whether to achieve self-esteem through work. When they do, they develop an intrinsic motivation to effort. Depending on the characteristics of the job to be filled, an employer may try, or not, to encourage this intrinsic motivation by an adequately...

We present a theorem on the existence of a maximal element for a correspondence which is upper hemi-continuous in some variables and which satisfies with respect to the other ones one the following conditions : (i) lower semi-continuous if the space has a finite dimension, (ii) lower...

The various macro econometrics models for inflation are helpless when it comes to the pricing of inflation derivatives. The only article targeting inflation option pricing, the Jarrow Yildirim model (2000), relies on non observable data. This makes the estimation of the model parameters a non...

Despite the recent advances in the theory of location, the analysis of the role of services surrounding production activity has been largely neglected. This paper analyzes the co-location of a multinational firm's value chain in the enlarged European Union. Depending on its particular...

This paper aims to show how the neo-classical current, which has yet absorbed development as one of its components, is trapped in a deep crisis, and how its domination can be understood in the theoretical field tightly linked to that of neo-liberalism on the policies of development.

In a previous work, we have developed a model in which agents choose whether to achieve self-esteem through work. When they do, they develop an intrinsic motivation to effort. The analysis was restricted to an employment relation (employers were monopsons). In the present study, we analyze the...

Product diversity is a long-debated issue in economics. We remind that mainly two questions have been given answers : (a) To which extent does the market provide diversity ? (b) Why should this diversity be promoted ? The first one stands out as the core of most articles on product diversity,...

The goal of this paper is to draw some lessons for economic theory from research in psychology, social psychology and, more briefly, in biology, which purports to explain the «formation» of social preferences. We elicit the basic mechanisms whereby a variety of social preferences are...

The disparity between the development paths followed by the economies of a limited number of countries, known as «emerging», and the bulk of the other developing countries has shown the limitations of previous development strategies. As a consequence, at the beginning of the 1990s, the...

This paper proposes a new empirical representation of inflation expectations errors in a Space-State Markov-Switching framework. We explicitly identify the dynamics of inflation expectation errors using the expectations augmented Markov-Switching Phillips curve as a measurement equation. In this...
