Dans cet exposé, on se propose de montrer comment on peut résoudre des EDP à l'aide de théorèmes de point fixe. On utilisera le Théorème de l'application contractante pour établir l'existence et l'unicité de solution pour une équation de Schrödinger, et le Théorème de Schauder pour une autre...

Recent evidence on the impact of information provision on service delivery has been mixed, with overall outcomes even worsening in certain cases. We examine the market-wide impact of an intervention that provides school and child-level learning report cards in a randomly selected half of 112...

We consider a circular deconvolution problem, where the density f of a circular random variable X has to be estimated nonparametrically based on an iid. sample from a noisy observation Y of X. The additive measurement error is supposed to be independent of X. The objective of this paper is the...

Consider a seller of a divisible good, facing several identical buyers. The quality of the good may be low or high, and is the seller's private information. The seller has strictly convex preferences that satisfy a single-crossing property. Buyers compete by posting arbitrary menus of contracts....

Investors value the liquidity and safety of U.S. Treasury bonds. We document this by showing that changes in Treasury supply have large effects on a variety of yield spreads. As a result, Treasury yields are reduced by 72 basis points, on average over the period from 1926-2008. The low yield on...

We propose a comparison across four types of demand models: a pure logit model, a logit model with random coefficients, a pure nested logit model and a nested logit model with random coefficients. Through the application of these techniques to a recent dataset on the European car market, we show...

The exchange of small and medium sized gifts is common practice in many industries. We focus on situations where the receiver of the gift has to take a decision on behalf of a third party and where the gift giver wants to influence this decision. Examples include physicians who receive gifts from...

We examine what can be learned about the coefficients of a single index dynamic binary response models with individual effects when repeated cross sections instead of genuine panel data are available. Unlike the existing literature, we allow for time varying variables among the regressors. We show...

There exist several characterizations of concavity for univariate functions. One of them states that a function is concave if and only if it has non-increasing differences. This definition provides a natural generalization of concavity for multivariate functions, called inframodularity. This paper...

This paper tests the hypothesis that the high prevalence of homicides in the US South stems from the fact that the region was settled by herders, chief among them the Scots and Scots-Irish. Herding societies tend to develop a “culture of honor” because violence is necessary to preserve a reputation...
