We discuss statistical inference problems associated with identification and testability in econometrics, and we emphasize the common nature of the two issues. After reviewing the relevant statistical notions, we consider in turn inference in nonparametric models and recent developments on...

In this paper, we develop finite-sample inference procedures for stationary and nonstationary autoregressive (AR) models. The method is based on special properties of Markov processes and a split-sample technique. The results on Markovian processes (intercalary independence and truncation) only...

In the 1970s, Thomas C. Schelling proposed a model which claimed to show that a high degree of spatial segregation can result from individual preferences which do not in themselves aim to achieve such a degree of collective segregation. A perverse effect seems therefore to occur. However, the...

After reviewing the ex ante appeal of Benford's law to detect fraud, the known limitations are introduced. Then, an example states that this statistical tool could not allow to make out the presence of accounting fraud for fashion good sales.

The paper addresses the issue of the impact of asymmetric information on risk aversion of litigant parties in a model à la Bebchuk. First we study the case where the plaintif is the informed party, and characterize the equilibrium with and without a pretrial negociation round. Then, we focuse...

This article analyzes the economic effeciency of legal rules of bankruptcy. It aims to answer the following question : do the legal rules of bankruptcy allow an efficient solution to the problem of sauve-qui-peut or opportunistic behavior inherent in bankruptcy firm ? I adopt a model of games...

This paper analyzes the incentive properties of the standard and burden of proof for a finding of negligence, when evidence about injurers' behavior is imperfect and rests with the parties. We show that the `preponderance of evidence' standard used in common law, together with ordinary exclusion...

La procédure française de plaider coupable suscite, depuis sa mise en place, de nombreux débats au coeur desquels apparaissent la liberté accordée aux magistrats dans leur prononcé de peines et la divergence de peines selon le niveau de ressources du prévenu et de surcroît selon le type...
