Much of the research on ethnicity, development and conflict implicitly assumes that ethnic groups act collectively in pursuit of their interests. Collective political action is typically facilitated by political parties able to make credible commitments to pursue group interests. Other work,...

Does radio access improve public service provision? And if so, does it do so by increasing government accountability to citizens, or by persuading households to take advantage of publicly-provided services? Prior research has argued that citizens with greater access to mass media receive greater...

Broad consensus exists that the ability of political actors to make credible commitments is key to development. An important and little-explored determinant of the credibility of political commitments is the existence of organizations that facilitate citizen collective action to sanction...

The government provision of free or subsidized bed nets to combat malaria in Benin allows the identification of new channels through which mass media affect public policy outcomes.
