My current research interests are motivated by welfare issues in low-income economies. My recent work is concerned with child mortality, malnutrition, child labour, primary education, intra-household resource allocation, altruism, gender, and imperfections in credit and labour markets. I have used large-scale integrated household survey data from Africa and Asia in my research. My doctoral work was concerned with questions of labour demand, wage dispersion, and aggregate unemployment and productivity. This analysis used industry-state panel data that covered the early phase of economic reform in India.
