We present a choice model based on agent interaction. Interaction is modeled as face-to-face communication that takes place on a regular periodic lattice with decision-makers exchanging information only with immediate neighbors. We investigate the long-run (equilibrium) behavior of the resulting...

We examine a society in which individuals gain utility from income and social approbation. Approbation is given to an unobservable trait, signalled through social mobility. Two environments are studied: in one players care for absolute approbation; in the other relative approbation matters. In...

Empirical research on strategic alliances has focused on the idea that partners are selected on the basis of social capital considerations. In this paper we emphasize instead the role of complementary knowledge stocks and knowledge dynamics, which have received surprisingly limited attention...

Abstract Innovation is a source of increasing productivity, but also of stress. Psychological research shows that individual productivity increases and then decreases as stress levels increase. Agents' stress levels are determined by their own coping ability and by positive and negative...

This paper analyzes empirically whether expansion of a university system affects local industry innovation. We examine how the opening of new university schools in Italy during 1985–2000 affected regional innovation. We find that creation of new schools increased regional innovation activity...

In traditional economics models of perfect competition agent's interactions are all mediated through the market. Interactions are anonymous, global and indirect. This is a powerful model, but we see many instances in which one, and sometimes all, of the previous characteristics fail to hold...

We study whether student-advisor gender and race composition matters for publication productivity of Ph.D. students in South Africa. We consider all Ph.D. students in STEM graduating between 2000 and 2014, after the recent systematic introduction of doctoral programs in this country. We...
