|September 2015||Toilets Can Work: Short and Medium Run Health Impacts of Addressing Complementarities and Externalities in Water and Sanitation|
with Esther Duflo, Michael Greenstone, Thomas Clasen: w21521
Poor water quality and sanitation are leading causes of mortality and disease in developing countries. However, interventions providing toilets in rural areas have not substantially improved health, likely because of incomplete coverage and low usage. This paper estimates the impact of an integrated water and sanitation improvement program in rural India that provided household-level water connections, latrines, and bathing facilities to all households in approximately 100 villages. The estimates suggest that the intervention was effective, reducing treated diarrhea episodes by 30-50%. These results are evident in the short term and persist for 5 years or more. The annual cost is approximately US$60 per household.
|July 2015||Does Development Aid Undermine Political Accountability? Leader and Constituent Responses to a Large-Scale Intervention|
with Ahmed Mushfiq Mobarak: w21434
Comprehensive evaluation requires tracking indirect effects of interventions, such as politicians and constituents reacting to the arrival of a development program. We study political economy responses to a large scale intervention in Bangladesh, where 346 communities consisting of 16,600 households were randomly assigned to control, information or subsidy treatments to encourage investments in improved sanitation. In one intervention where the leaders’ role in program allocation was not clear to constituents, leaders react by spending more time in treatment areas, and treated constituents appear to attribute credit to their local leader for a randomly assigned program. In contrast, in another lottery where subsidy assignment is clearly and transparently random, the lottery winners do not ...
|January 2014||Incentives, Selection and Productivity in Labor Markets: Evidence from Rural Malawi|
with B. Kelsey Jack: w19825
An observed positive relationship between compensation and productivity cannot distinguish between two channels: (1) an incentive effect and (2) worker selection. We use a simplified Becker-DeGroot-Marschak mechanism, which provides random variation in piece rates conditional on revealed reservation rates, to separately identify the two channels in the context of casual labor markets in rural Malawi. A higher piece rate increases output in our setting, but does not attract more productive workers. Among men, the average worker recruited at higher piece rates is actually less productive. Local labor market imperfections appear to undermine the worker sorting observed in well-functioning labor markets.
