Prices versus exams as strategic instruments for competing universities

In this paper we investigate the optimal choice of prices and/or exams by universities in the presence of credit constraints. We first compare the optimal behavior of a public, welfare maximizing, monopoly and a private, profit maximizing, monopoly. Then we model competition between a public and a private institution and investigate the new role of exams/prices in this environment. We find that, under certain circumstances, the public university may have an interest to raise tuition fees from minimum levels if it cares for global welfare. This will be the case provided that (i) the private institution has higher quality and uses only prices to select applicants, or (ii) the private institution has lower quality and uses also exams to select students. When this is the case, there are efficiency grounds for raising public prices

Le Chercheur dans l'institution scolaire: l'analyse de l'enseignement des nanobiotechnologies dans une classe de terminale scientifique

Nous présentons dans cette communication une expérimentation innovante basée sur l'enseignement des nanotechnologies. Débutée en 2006, elle s’inscrit sur une durée de 3 ans. Les élèves participant à ce projet pourront observer et mener des expériences à l’échelle moléculaire, comprendre les propriétés nouvelles de la matière liées à cette dimension de réduction dans le but d’application spécifiques, impliquant les outils mathématiques, physiques et chimie ainsi que la biologie. L’interdisciplinarité est un des fondements de ce projet qui a mobilisé la collaboration d'enseignants de diverses disciplines

Entrepreneurship, ties and relational networks: the case of a public-private cross-border tourism product

The thesis aims to understand the processes of entrepreneurship that try to create businesses or products with a high degree of complexity. This complexity comes from the fact that these products or initiatives can only be viable with the concurrence of a large number of heterogeneous actors (public, private, from different regions, etc..) which interact in a relational context. A case with these characteristics is the Camí dels Bons Homes. The thesis analyzes the evolution of the relational network from the point of view of its structure and content of its links. The results show and explain the observed changes in the network structure and the changes in the ties content. This analysis of the content of ties contributes to a new systematization and operationalization of ties’ content. Moreover this analysis takes in account negative ties, a less discussed issue in literature.
