Equivalence scales are routinely applied to adjust the income of households of different size and composition. Because of their practical importance for the measurement of inequality and poverty, a large number of methods for the estimation of equivalence scales have been proposed. Until now, no...

We study the causes of "nutritional inequality": why the wealthy eat more healthfully than the poor in the U.S. Exploiting supermarket entry, household moves to healthier neighborhoods, and purchasing patterns among households with identical local supply, we reject that neighborhood environments...

In China, tobacco consumption is a leading risk factor for non-communicable diseases, and understanding the pattern of socio-economic inequalities of tobacco consumption will, thus, help to develop targeted policies of public health control. Data came from the China Health and Retirement...

A century ago, Thorstein Veblen introduced socially contingent con-sumption into the economic literature. This paper complements the scarceempirical literature by testing his conjecture on South African householddata and nds that Black and Coloured households spend relatively moreon visible...

Was the increase in income inequality in the US due to permanent shocks or merely to an increase in the variance of transitory shocks? The implications for consumption and welfare depend crucially on the answer to this question. We use CEX repeated cross-section data on consumption and income to...

This paper studies the transmission of wage shocks into consumption across families that exhibit unobserved preference heterogeneity. Heterogeneity and preferences over consumption and family labor supply are nonparametric. I show that any moment of the joint distribution of policy-relevant wage...

There is vast literature examining how households’ income and consumption change over the life cycle. These studies, however, are usually restricted to developed economies. The main objective of this paper is to add to this literature by investigating the life cycle profiles and relative...
