We run a novel field experiment to link managers of African manufacturing firms. The experiment resembles the many forms of interaction that business and community organizations offer to their members. The design features exogenous link formation, exogenous seeding of information, and exogenous...

We investigate whether the prospect of redistribution hinders the formation of efficiency-enhancing groups. We conduct an experiment in a Kenyan slum, Ugandan villages, and a UK university town.

Mobile phone coverage has expanded considerably throughout the developing world, particularly within sub-Saharan Africa. Existing evidence suggests that increased access to information technology has improved agricultural market efficiency for consumer markets and certain commodities, but there...

Patterns of correlation in innovation and contractual practices among manufacturing firms in Ethiopia and Sudan are documented. Network data that indicate whether any two firms in the utilized sample do business with each other, buy inputs from a common supplier, or sell output to a common...

This study estimates the benefits that Indian farmers derive from market and weather information delivered to their mobile phones by a commercial service called Reuters Market Light (RML). We conduct a controlled randomized experiment in 100 villages of Maharashtra. Treated farmers associate RML...

This study analyzes the effects of differences in survey frequency and medium on microenterprise survey data. A sample of enterprises were randomly assigned to monthly in-person, weekly in-person, or weekly phone surveys for a 12-week panel. The results show few differences across the groups in...
