There is wide variation in how consumption is measured in household surveys, both across countries and over time. This variation may confound welfare comparisons in part because these alternative survey designs produce consumption estimates differentially influenced by contrasting types of...

The present paper examines one of the central elements of evolutionary thinking - competition formalized by the replicator dynamics mechanism. Using data on product characteristics of automobiles sold on the German domestic market over the period 2001-2006, we construct a competitiveness or...

This paper uses data from the Russian Longitudinal Monitoring Survey (RLMS) to examine the relationship between nutritional status and both longer-run household resources and short-run fluctuations in household resources. We evaluate six measures of nutrition – gross energy intake, two...

The interplay of a differentiated indirect tax structure and the variation in expenditure patterns across households, leads to a possibly unequal distribution of indirect tax liabilities across the population. This paper uses the ninth round of the RLMS survey to assess the distributional...

We use administrative data for Norway to estimate an incomplete-market life-cycle model of retired singles and couples with a bequest motive, health-dependent utility, and uncertain longevity and health. We allow the parameters of the bequest utility to differ between households with and without...

Anthropologists have long documented substantial and persistent differences across social groups in the preferences and taboos for particular foods. One natural question to ask is whether such food cultures matter in an economic sense. In particular, can culture constrain caloric intake and...
