It is shown that a fixed cost of nominal price changes enhances the ability of firms to collude in an ologopolistic market for a homogeneous good. Nevertheless, harsh price competition with firms making no profit remains a possible outcome. The analysis focuses on stable symmetric steady states...

This article suggests that the global inefficiency which generally affects a production process is endogenous and depends on the incentives generated by the process environment. We propose to treat the usual correlation between the inefficiency and the regressors of the production frontier...

The paper reviews some recent theoretical contributions on the modelisation of time-inconsistent preferences, as well as implications for individual behavior. The focus is on the interpretation of the concepts and the link with concepts in psychology.

We study in this paper how the technological flexibility choices and equilibrium configurations depend first on the industry characteristics (demand function and cost parameters specific to the multiproduct flexible technology and to the product dedicated technologies) and, second, on the...

Rationalization of U.S. freight railroads following the Staggers Rail Act of 1980 had led to lower real rates for many agricultural and industrial shippers, but has also been accompanied by increasing industry concentration and (more recently) merger-related service disruptions. This has led...

This paper studies irreversible investment decisions of a risl neutral regulated firm which has costs of production and of investment known with certainty and constant over time, but subject to uncertainty on exogenous shocks to demand. These shocks follow a geometric Brownian motion. No...

We show that whether observing technological choices made by the competitors is possible or not has significant impact on the equilibrium technological configurations. Depending upon the industry characteristics, the strategic value of technological flexibility may be either positive or...

This paper makes some steps toward a formal political economy of environmental policy. Economists' quasi-unanimous preferences for sophisticated incentive regulation is reconsidered.
