This article provides a first empirical study of the determinants of the propensity to which academic scholars tend to perform interdisciplinarity research. For that purpose we introduce a measure of interdisciplinarity as the diversity of their research production across scientific domains. Our...

This paper aims to demonstrate that the strategic approach of network formation can generate networks that share the main structural properties of most real social networks. We introduce a spatialized variation of the Connections model (Jackson and Wolinski, 1996) in which agents balance the...

In this paper, we present a model of 'collective innovation' built upon the network formation formalism. In our model, agents localized on a circle benefit from knowledge flows from other agents with whom they are directly or indirectly connected. They support costs for direct connections which...

The modelling of networks formation has recently became the object of an increasing interest in economics. One of the important issues raised in this literature is the one of networks efficiency. Nevertheless, for non trivial payoff functions, searching for efficient network structures turns out...

In this article, we propose to extend the concept of stochastic dominance, extensively used in decision theory and social choice, to the comparison of composite outcomes, both the quality and quantity of which do matter. Unanimity of judgment among new classes of functions is also studied. We...

Most of the empirical and theoretical literature aimed at understanding the behavioral patterns that lead to the formation of social networks argue that such networks are clustered because agents like social closure, since it facilitates cooperation enforcement, for instance, or increases match...

This paper proposes a bayesian methodology to treat the who's who problem arising in individual level data sets such as patent data. We assess the usefullness of this methodology on the set of all French inventors appearing on EPO applications from 1978 to 2003.

We propose a concept to study the stability of social and economic networks when players are farsighted and allocations are determined endogenously. A set of networks is a von Neumann-Morgenstern farsightedly stable set with bargaining if there exists an allocation rule and a bargaining threat...
