The finiteness condition of vertical product differentiation models is translated into the taste distribution model first analyzed by Mussa and Rosen. For a utility function linear in quality, the necessary and sufficient condition for finiteness is that the cost function with respect to quality...

Hall [1978] showed that the life cycle consumption hypothesis implies a first order autoregressive process for the marginal utility of consumption. This paper extends his results by showing that an appropriate pattern of rational habits will lead to an arbitrary autoregressive integrated moving...

This research empirically examines the relationship between economic development and the progression of economic thought. It is based on three propositions: 1) economic development progresses by long waves, 2) long waves induce a cyclical pattern of general entrepreneurial and managerial...

This paper studies the dynamic properties of the labour demand model with non-convex adjustment costs proposed by Bentolila and Bertola [1990]. With this model we evaluate the importance of the firing costs, following a great shock, for the dynamics of adjustment of the aggregated labour demand...

The author investigates the reasons why the Soviet reform programme is running into increasing difficulties. He argues that the budget deficit is the central characteristic of the new crisis of stagnation. On the one hand, it represents a direct reflection of the severe structural problems of...

This paper reviews four decades of economics research on the brain drain, with a focus on recent contributions and on development issues. We first assess the magnitude, intensity and determinants of the brain drain, showing that brain drain (or high-skill) migration is becoming the dominant...

European countries need to expand employment among older individuals. Many papers have examined this issue from different angles. However, very few seem to have considered its gender dimension properly, despite evidence that lifting the overall senior employment rate requires significantly...

Cet article s’interroge sur les limites bio-physiques à la croissance économique, et en particulier sur les conditions susceptibles de conduire à l’effondrement de l’économie. L’intention est d’étudier comment la naissance et la croissance (à travers l’accumulation du capital)...

Commodity currency literature recently stressed the importance of commodity prices as a determinant of real exchange rates in developing countries (Cashin, Cespedes and Sahay 2004). We provide new empirical evidence on this issue by focusing on countries which are specialized in the export of...
