March 2019Unity in Diversity? How Intergroup Contact Can Foster Nation Building
with Samuel Bazzi, Arya Gaduh, Maisy Wong: w25683
We use a population resettlement program in Indonesia to identify long-run effects of intergroup contact on national integration. In the 1980s, the government relocated two million ethnically diverse migrants into hundreds of new communities. We find greater integration in fractionalized communities with many small groups, as measured by national language use at home, intermarriage, and children's name choices. However, in polarized communities with a few large groups, ethnic attachment increases and integration declines. Residential segregation dampens these effects. Social capital, public goods, and ethnic conflict follow similar patterns. Overall, our findings highlight the importance of localized contact in shaping identity.
July 2010Collective Action in Diverse Sierra Leone Communities
with Rachel Glennerster, Edward Miguel: w16196
Scholars have pointed to ethnic and other social divisions as a leading cause of economic underdevelopment, due in part to their adverse effects on public good provision and collective action. We investigate this issue in post-war Sierra Leone, one of the world's poorest countries. To address concerns over endogenous local ethnic composition, and in an advance over most existing work, we use an instrumental variables strategy relying on historical ethnic diversity data from the 1963 Sierra Leone Census. We find that local ethnic diversity is not associated with worse local public goods provision across a variety of outcomes, regression specifications, and diversity measures, and that these "zeros" are precisely estimated. We investigate the role that two leading mechanisms proposed in the ...

December 2006Sudden Flight and True Sudden Stops
with Francis E. Warnock: w12726
We extend the sudden stops literature by allowing crisis episodes to be caused by either the retreat of global investors, as is assumed but not shown in the extant literature, or the sudden flight of local investors. We find that almost half of the previously defined sudden stops are actually episodes of sudden flight. Compared to sudden flight, true sudden stops are bunched and are associated with greater slowdowns in economic activity and sharper currency depreciations. We show that the empirical regularities of sudden flight and true sudden stops are consistent with theoretical models that incorporate gross capital flows and information asymmetries.
