The income elasticity of calories generally is substantially smaller than the income elasticity of food expenditure. One reason may be an increasing concern for food variety as incomes increase. Food variety can be linked with two characteristics of food indifference curves: (1) curvature and...

The World Bank and others maintain that the major mechanism for improving nutrition in poor communities is increases in income. Aggregate estimates of food expenditure are consistent with such a possibility, implying income/expenditure elasticities close to one. However, the high degree of...

This paper attempts to simultaneously study the production and impact of patenting in a less-developed country, using panel firm-level data for the period 1975-79 for India. The authors' results suggest that, despite the limited protection of intellectual property rights in India, patenting is...

Using panel data for rural South India, a fixed-effects individual wage equation and farm production function are estimated that have calorie intake and nutritional status (weight-for-height) of workers as their arguments. Neither market wages, nor farm output, are observed to be responsive to...

Unequal access to financing for education may be an important source of educational differences. The authors develop a model relating sib schooling and earnings similarities to sibship, size with and without equal access, and estimate it for the education of veterans, for whom the GI Bill...

Birth-order effects are posited by many to affect earnings and schooling. The authors show how such effects can be interpreted to shift either the earnings possibility frontier for siblings or parental preferences. The authors find empirical evidence for birth- order effects on (age-adjusted)...

The authors show how comparisons between the within-twin correlations of human capital outcomes across identical and nonidentical twins can be used to identify the variability in the individual-specific component of endowments and the responsiveness of schooling to individual-specific endowments...
