In a multiperiod economy with incomplete markets and assets that exhibit a payoff depending on price history, we show that one need not perturb back office and settlement feature of assets to get endowment generic existence of an equilibrium. We exhibit a class of assets -transverse assets - and...

We present a model that focuses on the links between location and educational choices in South African cities. Be comparing the Apartheid city and the post-Apartheid city, we show that the inequality in South Africa between blacks and whites decreases when Apartheid laws are removed.

In a previous paper, Abouda and Chateauneuf proved that for RDEU maximizing MM with non-increasing marginal utility, positivity of the bid-ask spread can be identified with a very weak form of risk aversion SMRA. We perform here a more thorough study of SMRA, firstly in a general setting, and...

In this paper, we first give a direct proof of the existence of Edgeworth equilibria for exchange economies with consumption sets which are (possibly) unbounded below. The key assumption is that the individually rational utility set is compact. It is worth noticing that the statement of this...

In this paper we generalize Magill and Shafer's analysis of generically complete markets in the presence of an open-ended horizon. Until now, the genericity argument in Duffie and Shafer has no satisfactory generalisation to the case of an open ended horizon. These difficulties are threefold:...

Dans ce rapport, nous donnons un calcul analytique du gradient de la log-vraisemblance dans le cas gaussien. Nous étudions aussi un estimateur recursif qui donne de bons resultats sur des donnees simulees.
