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...

In the chapter 4 of their book "Endogenous Growth Theory", P. Aghion and P. Howitt introduce environemental pollution in an aggregate Schumpeterian model and they characterize the optimal path. In this paper , we study the equilibria in a decentralized compatible with their model. First study...

As the structure of consumer preferences plays a crucial role in the analysis of differentiated product markets, estimation of demand systems is a sensitive task. This paper contributes to this project in two ways. First, we develop a method to deal with the simultaneous choice of an equipment...

We consider a kernel based approach to nonlinear canonical correlation analysis and its implementation for time series. We deduce various diagnostics for reversible processes and gaussian processes. The method is first applied to a stimulated series satisfying a diffusion equation allowing us to...
