A directed network game of imperfect strategic substitutes with heterogeneous players is analyzed. We consider concave additive separable utility functions that encompass the quasi-linear ones. It is found that pure strategy Nash equilibria verify a non-linear complementarity problem. By...

We consider a decision maker facing uncertainty which behaves as a subjective expected utility maximizer. The value of information is traditionally captured as a greater expected utility the decision maker can achieve by selecting a best strategy as information arrives. We deal with the limit...

[eng] This article presents a theoretical framework that uses an epidemic diffusion model and a rational choice model to conceptualize the decision to adopt a given technology. We estimate both models on a sample of 114 farmers in Reunion Island. The results show that the diffusion of new...
