This paper warns against the use of Marshallian welfare loss in applied analysis of market power. We show how to compute the Hicksian deadweight loss from an ordinary demand. Then, from an experiment using real data on twenty-one sectors of the French food industry, we find that the Marshallian...

[eng] Losses of Welfare and Market Power in the French Food Industry by Pascal Lavergne, Vincent Réquillart and Michel Simioni . We study the practical problems of estimating losses of welfare resulting from market power. Particular attention is paid to the specification of demand functions,...

The purpose of this article is to assess whether food safety regulations imposed by the European Union in the 2000s may have induced a slow-down in the productivity of firms in the food processing sector. The impact of regulations on costs and productivity has seldom been studied. This article...

We propose two classes of consistent tests in parametric econometric models defined through multiple conditional moment restrictions. The first type of tests relies on nonparametric estimation, while the second relies on a functional of a marked empirical process. For both tests, a simulation...

We deal with the issue of testing the specification of a regression function. As a leading case, we consider testing for a pure noise model. We study the smallest local alternatives that can be detected asymptotically in a minimax sense. We propose a simple testing procedure that has asymptotic...
