In this paper, we investigate the impact of peers on own outcomes where all agents embedded in a network choose more than one activity. We develop a simple network model that illustrates these issues. We differentiate between the ‘seemingly unrelated’ simultaneous equations model where...

This paper studies the effect of organizational social capital on structural change in the context of socio-economic networks. In a networked economic system, organizational social capital is the outcome of a dynamic process; the effect of this process on firm performance is contingent on the...

The strength of weak ties is amongst the most important theories in the social sciences. One paradoxical element of the theory has been widely understood and valued—that weak ties connect disparate regions of social structure. Less appreciated, however, is the arguably more paradoxical...

Social networking sites make it easier for people to form, maintain, and identify relationships. Yet, building social capital also involves strengthening weaker ties. Can social networking sites help people strengthen pre-existing ties with others? In this paper, we theorize and test two...

The aim of this inquiry is to investigate the relationships among the antecedents of knowledge sharing effectiveness under the position of non-academic staff of higher learning institutions through an empirical test of a conceptual model consisting of trust, extrinsic and intrinsic motivation,...

We reconsider de Marti and Zenou (2017) model of friendship network formation where individuals belong to two different communities and costs of forming links depend on community memberships. Many inefficient friendship networks such as segregation can arise when all individuals are myopic. Once...

We study a model of social learning in networks where the dynamics of beliefs are driven by conversations of dissonance-minimizing agents. Given their current beliefs, agents make statements, tune them to the statements of their associates, and then revise their beliefs. We characterize the...
