This article analyzes the "escape from competition effect" in a step-by-step framework in which a succesful firm may either leapfrog the previous leader or catch-up its technology. Innovation and growth are affected by both the intensity of competition and the probability of leapfrogging.

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...

The Relations Between Science and Technology: what Implications for Public Policy? This article proposes an analysis of the science-technology interactions. The first part is historical and focuses on the transformations that resulted from the passage of a prescriptive knowledge (techniques) to...

This paper explores a licensor's choice between charging a per-unit royalty or a …fixed fee when her innovation is covered by a weak patent, i.e. a patent that is likely to be invali- dated by a court if challenged. Using a general model where the nature of competition is not speci…ed, we show...

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...

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...

In this paper we examine the implications of uncertainty over patent validity on patentholders' licensing strategies. Two licensing mechanisms are examined: per-unit royalty and up-front fee.We provide conditions under which uncertain patents are licensed in order to avoid patent litigation. It...

In this paper, we revisit the issue of licensing ‘weak' patents under the shadow of litigation. Departing from the seminal paper by Farrell and Shapiro [2008], we consider innovations of any size and not only ‘small' innovations, and we allow the number of licensees to be less than 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....
