A large literature has studied how peers affect behavior by exploiting the preexisting social network structure only. What if networks rewire in response to changes in the economic environment, such as a randomized intervention? We exploit a unique panel dataset that contains detailed...

Networks may rewire in response to interventions. We propose a measure of the total treatment effect for those situations where an intervention may affect the network structure. To build this measure, we develop a treatment response model allowing for dynamic peer effects. We illustrate our...

Con el objetivo de estudiar la asociación entre las características y los recursos de una red social y los hábitos financieros de sus miembros, aplicamos una encuesta en una comunidad académica acotada en la Ciudad de México. En consonancia con la literatura de redes y desarrollo...

Microfinance group lending with joint liability allows asset-poor individuals to replace physical collateral by social collateral. The literature on microfinance lacks a rigid framework for analyzing the consequences of using social collateral for borrowing behavior and repayment. This paper...

In a technology-driven, digital world, many of the largest and most successful businesses now operate as “platforms.” Such firms leverage networked technologies to facilitate economic exchange, transfer information, connect people, and make predictions. Platform companies are already...

This article aims to analyze under theory of graphs assumptions, small worlds approach, how the configuration of the global network of relations among board members of public companies listed in the Brazilian between 2004 and 2007 evolved. To verify the validity of small world approach, the...

Over recent decades, the on-going “digital revolution” has transformed many aspects of everyday life. Think of the increased power and shrinking size of personal computers and smartphones; the global expansion of the Internet and the new forms of social interaction that have been created; and,...

Mobile money allows households in Kenya to spread risk more efficiently. In this paper we show that these efficiencies are achieved through deeper financial integration and expanded informal networks. Active networks are more geographically dispersed and support more reciprocal financial...

Knowledge clusters are central places within an epistemic landscape, i.e. in a wider structure of knowledge production and dissemination. They have the organisational capability to drive innovations and create new industries. Examples of such organisations in knowledge clusters are universities...

We construct the topology of business networks across the population of firms in an emerging economy, Pakistan, and estimate the value that membership in large yet diffuse networks brings in terms of access to bank credit and improving financial viability. We link two firms if they have a common...
