To a large extent, information sharing is what nongovernmental organiz
ations (NGOs) do, and the costs of sharing information are falling dra
matically. Joining politics and economics, this paper builds an analyt
ical framework to illuminate how these falling costs are affecting inf
ormation-intensive NGOs in Latin America. Case studies describe the va
rious information-sharing outputs and inputs of nonprofit, NGO product
ion. I argue that the participatory activity of NGOs affects both poli
tical and economic realms, and that as the costs of sharing informatio
n fall, NGOs will be a more powerful link in the changing balance betw
een states, markets, and civil society. (C) 1997 Elsevier Science Ltd.
