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...

This paper introduces a spatialized variation of the Connections model of Jackson and Wolinski (1996). Agents benefit from their direct and indirect connections in a communication network. They are arranged on a circle and bear costs for maintaining direct connections which are linearly...

This paper analyses the modalities according to which a large European university collaborates with firms by exploring its relational portfolio. We address this issue by exploiting a database listing more than 1000 firms having collaborated with the University Louis Pasteur between 1990 and...

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...

In this paper we present an original model of sequential problem choice within scientific communities. Disciplinary knowledge is accumulated by solving problems emerging in a growing tree-like web of research areas. Knowledge production is sequential since the problems solved generate new...

This paper is concerned with the incentive properties of the Matthew Effect by which since Merton [1968] one is usually describing the various cumulative advantages that obviously affect academic competition. We introduce a model of sequential contests in which the agents that have initially...

This work explores and reviews the introduction of real option in the strategic management literature. The aim is to contribute to a better understanding of the origin of the real option. By distinguishing between shadow and real option, and implementing entrepreneurship in the traditional...

This paper analyzes a model of sequential parimutuel betting described as a two-horse race with a finite number of noise bettors and a finite number of strategic and symmetrically informed bettors. For generic objective probabilities that the favorite wins the race, a unique subgame perfect...

Demography-based income forecasting has recently gained enormous popu- larity. Malmberg and Lindh (ML, 2005) in an important contribution forecast global income by incorporating demographic age information where the vari- ables were assumed to be stationary. Drawing on the insights from recent...

We study the relations between compensation schemes and risk aversion of managers in a strategic framework. We first show that the use of relative performance evaluation (RPE) in compensation contracts reduces the equilibrium profits of Cournot firms if managers are not too risk averse. Second,...
