Laissez-faire versus Pareto∗

Consider two principles for social evaluation. The first, ‘laissez-faire’, says that mean-preserving redistribution away from laissez-faire incomes should be regarded as a social worsening. This principle captures a key aspect of liberal political philosophy. The second, weak Pareto, states that an increase in each individual’s disposable income should be regarded as a social improvement. We sh...

Faire bonne figure avec Mlpost

This article introduces MLPOST, an OCaml library for scientific drawing. It is based on METAPOST, which allows inclusion of LTEX fragments. OCaml is an appealing alternative to LTEX macro languages, dedicated languages and even to graphic tools. In particular, MLPOST users benefit from OCaml’s expressiveness and static typing. Finally, MLPOST features a declarative style, which differs from the...

Agrégation de ressources avec contrainte de distance : applications aux plateformes de grande échelle. (Resource clustering with distance constraint: applications to large scale platforms)

On the robustness of laissez-faire

This paper considers a model economy in which agents are privately informed about their type: their endowments of various goods and their preferences over these goods. While preference orderings over observable choices are allowed to be correlated with an agent’s private type, we assume that the planner/government is both uncertain about the nature of this joint distribution and unable to choos...

AUX Information Assisted HEVC

An AUX information assisted HEVC is described in this paper. This new functionality provides a tool for HEVC to determine the quantization parameter of CU based on auxiliary input. In this report, a saliency based auxiliary input is employed as a proof-of-concept. As shown in our subjective tests, the new tool achieves up to 12% bit rate reduction with negligible perceptual quality loss.
