Une importante littérature empirique est dévolue à la question du lien entre les facteurs financiers et les performances économiques des firmes. Dérivées du rejet de l’hypothèse classique de non incidence de la structure financière sur la dépense ou inscrites plutôt dans une logique...

We provide an overview of the workings of the National Science Foundation and the proposal review process, as well as some guidance in writing proposals for funding.

Five waves of the Panel Study of Income Dynamics (PSID), 1985-1989 including both wealth supplements, are used to construct an intertemporal budget constraint for selected single headed households. A new functional form of the dual consumer profit function rationalizing consumption, labor supply...

This article presents an equilibrium concept that, contrary to the traditional walrasian one, allows for the unbalance between supply and demand in different markets, making easier the analysis of those situations in which they differ persistently, as in the case of the labor market....

A Rational Shortlist Method (RSM) translates into economic language some sequential choice heuristics studied in psychology. We show that the use of this boundedly rational procedure can be detected from observed choice data through tests that are very similar to those used to detect `rational'...

The paper studies equilibria for economies with imperfect competition and non-convex technologies. Following Negishi firms maximise profits under downward-sloping perceived demand functions. Negishi's assumptions, in particular the assumption of a single monopolistic competitor in each market,...

A central prediction of the quasi-hyperbolic model of time preference is that consumers will be impatient over short-run tradeoffs. I present the first nonlaboratory test of this implication using data on the nutritional intake of food stamp recipients. Caloric intake declines by 10 to 15...

We study the problem of a regulator who must control the emissions of a given pollutant from a series of industries when the firms' abatement costs are unknown. We develop a mechanism in which the regulator asks firms to report their abatement costs and implements the most stringent emissions...

Two results showing the limitations of the “as if” methodology are proved under relatively mild assumptions. In an interpretation of the results, a competitive market cannot simulate the outcome of a market M in which the single price assumption does not hold. In a second interpretation, the...

Much attention has been paid to alternative fuel sources of late. Ethanol has been a politically popular alternative fuel additive and has recently been pushed to the forefront as a leading replacement to MTBE as an oxygenate. This paper examines the potential markets for ethanol, including...
