This paper introduces the choice of identity characteristics, and, commitments to these characteristics, in a network formation model where links costs are shared. Players want to link to the largest group given that linking costs are decreasing (increasing) in commitments for same (different)...

This paper develops a model of noncooperative network formation. Link formation is two-sided. Information flow is two-way. The paper is based on Bala and Goyal (2000) with the following difference in assumption: the value of information decays as it flows through each agent, and the decay is...

This paper develops a model of noncooperative network formation. Link formation is two-sided. Information flow is two-way. The paper is built upon Bala and Goyal. A unique assumption is that the value of information decays as it flows through each agent, and the decay is increasing and concave...

Nowadays, the understanding of the impact of social media and online news media on the emergence of extreme polarization in political discourse is one of the most pressing challenges for both science and society. In this study, we investigate the phenomenon of political polarization in the...

We argue in this paper that attention to one's blog is won by paying attention to other bloggers. We derive properties of blogging networks from a model where bloggers trade attention and content. The predictions from the model are then checked against a novel dataset from LiveJournal, a major...

In recent years, due to the growing supply of organic production, the economic performances and the competitive advantages of the farms, have become more dependent on network organisations in the supply chains. This evolution requires methodological approaches able to capture all the variables...

Properties of blogging networks are derived from a model where bloggers devote attention to others, produce content for others, and exchange attention with content within their network of relations. The predictions from the model are tested with a novel dataset from LiveJournal, a major blogging...

The paper explores the role social network capital might play in facilitating poor agents’ escape from poverty traps. We model endogenous network formation among households heterogeneously endowed with both traditional and social network capital who make investment and technology choices over...

This paper looks at the role of identity in the fragmentation of networks by incorporating the choice of commitment to identity characteristics, into a noncooperative network formation game. The Nash network will feature divisions based on identity, moreover, it will have layers of such...

In Mexico, social capital is used to get resources. People who do not have access to formal markets use their networks to acquire public and financing services, social insurance and social benefits. To test this, social capital indicators were built using the resources supplied by people as a...
