We present a simple and direct proof for a nonlinear Leray-Schauder type alternative for a large class of condensing or compact set-valued maps, containing convex as well as nonconvex valued maps.

Lexical parsing is the whole set of techniques to increase from a raw text to a sequence of tagged words ; these tags are morphological and grammatical information. Lexical parsing generally uses an electronic dictionary. But a few of them accommodate themselves to proper nouns that are a...

We present the model of games with incomplete information first introduced by Harsanyi and show the link with extensive form games with imperfect information. We provide then a construction of the universal type space of Mertens and Zamir together with some properties.

We are interested by Lyapounov exponents in the almost periodic Hamiltonian case.

Cumulative prospect theory was introduced by Tversky and Kahneman to combine the empirical realism of their original prospect theory with the theoretical advantages of rank-dependent utility. Preference axiomatizations were provided in several papers. All exosting axiomatizations, however, only...

We present and prove the equality between the core and the set of Walras allocations for a pure exchange economy with l goods and a continuum of consumers, represented by an atomless measure space.

This paper investigates the stability of households' consumption behaviour in France through a prcedure of discriminating between feedback and feedforward models connected to the notions of encompassing in invariance initially proposed by Hendry (1988).

This econometric study analyzes market bid functions for French Treasury Bills. We use the results of 125 discriminatory bill auctions during 1995 to determine the factors that affect the shape of the aggregate demand functions. We proceed in two step, we estimate the parameters of a logistic...
