Height, Health, and Inequality: The Distribution of Adult Heights in India

American Economic Review 2008 98(2), 468-474 open access
This paper explores the relationship between adult heights and the distribution of income across populations of individuals. There is a long literature that examines the relationship between mean adult heights and living standards. If adult height is set by the balance between food intake and charges to disease in early childhood, it is informative about economic and epidemiological conditions in childhood. Because taller populations are better-off, more productive, and live longer, the relationship between childhood conditions and adult height has become an important focus in the study of the relationship between health and wealth. Here I follow one of the tributaries of this main stream. A relationship between income and height at the individual level has implications for the effects of income inequality on the distribution of heights. These relationships parallel, but are somewhat more concrete than, the various relationships between income inequality and health that have been debated in the economic and epidemiological literatures, Richard G. Wilkinson (1996), Angus Deaton (2003).

Quality, Quantity, and Spatial Variation of Price

American Economic Review 1988
This paper develops and implements a method for estimating price elasticities of demand using cross-sectional household survey data. Geographically clustered households report unit values, which when corrected for quality effects and for measurement error, indicate the underlying spatial variation in prices, and can be matched to variation in demand patterns. A simple model of quality choice is proposed, while the correction for measurement error exploits the clustered design of such surveys. Data from a 1979 household survey from the Ivory Coast are used to estimate price elasticities for beef, meat, fish, cereals, and starches. Copyright 1988 by American Economic Association.

The Analysis of Consumer Demand in the United Kingdom, 1900-1970

Econometrica 1974 42(2), 341
[This paper considers the application of various models of consumer demand to United Kingdom time series from 1900 to 1970. As well as testing the various forms of the "Rotterdam" model, reparametrization of that system is carried out in order to test the linear expenditure system and the direct addilog system on an exactly comparable basis. A further variant of the Rotterdam model is also introduced; this is intermediate between symmetry and additivity and allows for the calculation of all cross price elasticities from information on own price and income elasticities alone. The results of testing these models on a nine commodity model using maximum likelihood estimation are presented and discussed. Unlike most previous work, and in spite of some anomalous results, the United Kingdom experience seems broadly consistent with neoclassical demand theory. However, all restrictions more stringent than those directly implied by the theory are rejected, though it is maintained that these may still be of considerable practical significance in particular instances.]

Functional Forms for Labor Supply and Commodity Demands with and without Quantity Restrictions

Econometrica 1981 49(6), 1521
One of the most important current questions in economic analysis is whether or not labor markets clear in the short run. To answer this, it is necessary to be able to distinguish between restricted and unrestricted behavior by consumers supplying labor. This paper investigates the forms of preferences which lie behind linear models of labor supply, and derives the functional forms for commodity demands which accompany them, both with and without quantity restrictions in the labor market. Simple linkages between restricted and unrestricted demands are also considered as is the question of perfect aggregation over consumers in the presence of quantity restrictions.

Growth and Saving Among Individuals and Households

The Review of Economics and Statistics 2000 82(2), 212-225
Abstract-The lifecycle theory of saving and consumption predicts that changes in an economy's rate of economic growth will affect its aggregate saving rate by changing the lifetime resources of younger people relative to older people. However, studies that track the saving behavior of cohorts of household heads over time as they age have yielded estimates of age-saving profiles that are too flat for growth to have much effect on the aggregate saving rate. One problem with the cohort approach is that multigenerational households are common in many counties, and the age-saving profiles of households may be quite different from the age-saving profiles of individuals that make up households. In this paper, we propose a method for estimating individual age-saving profiles using household data. This method is applied to data from Taiwan and Thailand. We find that the individual method yields results that are more favorable to the lifecycle model. These results imply that changes in the rate of economic growth may in some circumstances have large effects on the aggregate saving rate. However, the size and sign of these effects depends on the rate of economic growth and the rate of population growth, and in many cases the effect of growth on saving is small. I.

Aging and Inequality in Income and Health

American Economic Review 1998
In our earlier work, we used data from the National Health Interview Survey (NHIS) to examine life-cycle patterns in health status and in the joint distribution of health status and income (Deaton and Paxson, 1998). In this paper we summarize and extend those results, and provide new evidence from the Panel Study of Income Dynamics (PSID). Both surveys contain a measure of household income, and collect information on an ordinal measures of self-reported health status (SRHS) that ranges from 1 (excellent) to 5 (poor). Section I concerns problems related to the measurement of inequality in health. Section II presents evidence from the two surveys on health and income inequality.
