June 2014Intra-household Welfare
with Costas Meghir: w20189
In this paper we develop an approach to measuring inequality and poverty that recognizes the fact that individuals within households may have both different preferences and differential access to resources. We argue that a measure based on estimates of the sharing rule is inadequate as an approach that seeks to understand how welfare is distributed in the population because it ignores public good and the allocation of time to market work, leisure and household production. We develop a money metric measure of welfare that accounts for public goods (by using personalized prices) household production and for the allocation of time.
Intrahousehold Inequality
with Costas Meghir: w20191
Studies of inequality often ignore resource allocation within the household. In doing so they miss an important element of the distribution of welfare that can vary dramatically depending on overall environmental and economic factors. Thus, measures of inequality that ignore intra household allocations are both incomplete and misleading. We discuss determinants of intrahousehold allocation of resources and welfare. We show how the sharing rule, which characterizes the within household allocations, can be identified from data on household consumption and labor supply. We also argue that a measure based on estimates of the sharing rule is is inadequate as an approach that seeks to understand how welfare is distributed in the population because it ignores public goods and the allocation of ti...
January 2011Heterogeneity and Risk Sharing in Village Economies
with Krislert Samphantharak, Sam Schulhofer-Wohl, Robert M. Townsend: w16696
We measure heterogeneity in risk aversion among households in Thai villages using a full risk-sharing model and complement the results with a measure based on optimal portfolio choice. Among households with relatives living in the same village, full insurance cannot be rejected, suggesting that relatives provide something close to a complete-markets consumption allocation. There is substantial heterogeneity in risk preferences estimated from the full-insurance model, positively correlated in most villages with portfolio-choice estimates. The heterogeneity matters for policy: Although the average household would benefit from eliminating village-level risk, less-risk-averse households who are paid to absorb that risk would be worse off.
