Dans le cadre de collaborations avec des collègues biologistes, je me suis souvent trouvé confronté à la question : "le referee nous dit qu'il vaudrait mieux faire un test non paramétrique parce que [les données ne sont pas gaussiennes / les tailles d'échantillon trop faibles / ... ] ; qu'en penses...

This paper makes two main contributions to inference for conditional quantiles. First, we construct a generic confidence interval for a conditional quantile from any given estimator of the conditional quantile via the direct approach. Our generic confidence interval makes use of two estimates of...

Je vous propose une petite introduction à l'estimation non-paramétrique sous R. Nous aborderons principalement l'estimation de la densité et de la régression dans un cadre simple d'abord, puis pour des problèmes plus proches de ceux rencontrés dans la pratique (pb multidimensionnel, variables...

In many moral hazard problems, the principal evaluates the agent's performance based on signals which the agent may suppress and replace with counterfeits. This form of fraud may affect the design of optimal contracts drastically, leading to complete market failure in extreme cases. I show that in...

Banks are optimally opaque institutions. They produce debt for use as a transaction medium (bank money), which requires that information about the backing assets not be revealed, so that bank money does not fluctuate in value, reducing its efficiency in trade. This need for opacity conflicts with...

In a general Hilbert framework, we consider continuous gradient-like dynamic systems for constrained multi-objective optimization, involving (possibly non-smooth) convex objective functions. We prove a descent property for each objective function, and the convergence of trajectories to weak Pareto...

It is well established that horizontal cross-ownership may decrease competition. One reason is that cross-ownership enables information- and profit sharing, which increases the prospects for collusion. Another reason is that cross-ownership may induce unilateral incentives to reduce output, which...
