This dissertation examines topics related to development, environment and health in developing countries using empirical methods. In the first chapter, I study how developing countries can increase enforcement to reduce subsidy leakage in public programs, by investing in the state capacity to target program beneficiaries. This chapter further attempts to understand how the formal sector and black market respond to a policy that reduces diversion of a subsidized commodity. I explore these questions using the case of a Unique ID-based direct fuel subsidy transfer policy in India. Second chapter focuses on the health and wealth trade off near mineral mining operations in developing countries. Using extensive data on mining, health outcomes and assets from 44 developing countries, this study quantifies the wealth gain and adverse health impact of mineral mining. With a number of empirical strategies, this study shows that, despite high wealth gains, how heavy metal mining significantly increases the level of anemia in women and stunting in children living near mines. In the third chapter, I estimate demand for a water quality diagnostic product -- arsenic testing, when it is offered at a price. I further look into various aspects related to selection, learning and households behavioral response to the information. This study is based on a field experiment in Bihar, India.

M. Tech. Comparative Local Development. Department of Economics. / Local systems of innovation are defined as spatial concentrations of market and non-market agencies that combine to create new products and/or services in specific lines of economic activity. If successful, local systems of innovation bring about local economic development, building up the economic capacity of a local area in order to improve its economic future and the quality of life for its population.
