This compilation of original papers selected from the 19th Conference on Postal and Delivery Economics and authored by an international cast of economists, lawyers, regulators and industry practitioners addresses perhaps the most significant problem that has ever faced the postal sector –...

This paper discusses the solution of nonlinear integral equations with noisy integral kernels as they appear in nonparametric instrumental regression. We propose a regularized Newton-type iteration and establish convergence and convergence rate results. A particular emphasis is on instrumental...

This paper proposes a simple algorithm for the numerical computation of the non parametric IV quantile estimation. This algorithm is based on the Landweber iterations for solving a nonlinear integral equation. The paper is illustrated by numerical simulations.

The paper of James Heckman is an extremely interesting survey of a huge literature on evaluation estimators with a special attention to matching estimation. The article essentially concentrates on models with two levels of treatment (1 for treated and 0 for non treated). My discussion will...

This paper considers the estimation of panel data models by first differences in the presence of endogenous variables and under an instrumental variables condition. This framework leads to the resolution of linear inverse problems solved using a Tikhonov regularization with L2 or Sobolev...

[fre] Équilibre approximatif et règle intuitive : une application aux appels d'offres dans l'industrie spatiale par Olivier Armantier, Jean-Pierre Florens et Jean-François Richard . Nous adoptons dans cet article la notion d'équilibre approximatif obtenu à partir d'une "règle intuitive"....

Conditional efficiency captures efficiency of firms facing heterogeneous environmental conditions. Traditional approaches estimate nonparametrically conditional distribution requiring smoothing techniques. We rather use a flexible nonparametric location-scale model to eliminate the dependence of...
