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.

In this paper we present a meta-heuristic, known as a genetic algorithm, in order to solve the problems of (weigthed) independent set (IS), vertex covering (VC), set packing (SP) and maximum clique (MC).

When calibrated, the Mortensen & Pissarides [1994] is able to produce some stylized facts highlighted by empirical studies on US gross job flowa. However, other stylized facts concerning their asymmetric properties are generally neglected at the aggregate level. The aim of this paper is to test...

The purpose of this paper is to focus on Henry L. Moore's transfers from the natural sciences that enabled him to shape statistical economics. This construction led him to search statistical methods that could help him to bridge the data-theory gap, and I should like to analyze the consequences...
