Multi-echelon distribution schemes are one of the most common strategies adopted by the transport companies in an aim of cost reduction, but their identification in scientific literature is not always easy due to a lack of unification. This paper presents the main concepts of two-echelon...

This paper studies how the imperfect collateral assignments of patents contribute to "deep pockets'' savings of innovative firms facing random investment opportunities in research and development (R&D) and determine the growth of their innovations, using a version of the Kiyotaki and Moore...

La logistique urbaine est une discipline née dans les années 1990, avec pour objet de répondre aux questions qui se posent autour des nuisances provoquées par le transport de marchandises en ville. Très étudiée en termes de politiques publiques et de méthodes d'aide à la décision...

Cet article présente un cas particulier de régression non fondée, lorsqu'une variable dépendante a un coefficient de corrélation simple proche de zéro avec deux autres variables, qui sont en revanche très corrélées entre elles. Dans ce type de régressions, les paramètres mesurant la...

This paper studies under which conditions the share of profit in value-added, financial constraints on investment and capital shortage may foster unemployment and may limit the growth of capital and/or the growth of aggregate demand, in a stock-flow consistent model. The efficiency of...

In this paper, a modelling framework to complete the recent scientific works on urban goods modelling is proposed. More precisely, we introduce a substitution procedure that estimates the number of trips and the corresponding travelled distances for shopping drive, home delivery and reception...

In logistics, freight transportation is a major source of income in a country's economy. One of the most popular strategies is logistics sharing, which is a complex problem due to the involved stakeholders. Moreover, the current several transport operations are extremely expensive due to the...

Collaborative transportation and logistics pooling are relatively new concepts in research, but are very popular in practice. In the last years, collaborative transportation seems a good city logistics alternative to classical urban consolidation centres, but it is still in a development stage....

Ce document est une première tentative de en perspective les flux de transport de marchandises avec le fonctionnement de la ville et la morphologie urbaine, à travers les différentes étapes franchies au cours de ces vingt dernières années en termes de méthode et d'outils de connaissance...

Using a large panel of 6946 French manufacturing firms, this paper investigates the effect of sales, of the cost of capital and of liquidity constraint variables (cash flow or cash stock) on the stock of capital from 1990 to 1999. The user cost elasticity is at the most 0.26 in absolute terms...
