This paper examines the consequences of social security reform for the inequality of consumption across individuals. The idea is that inequality is at least in part the result of individual risk in earnings or asset returns, the effects of which accumulate over time to increase inequality within...

We investigate age-specific mortality in Britain and the United States since 1950. Neither trends in income nor in income inequality provide plausible explanations. Britain and the US had different patterns of income growth but similar patterns of mortality decline. Patterns of income inequality...

People whose family income was less than $5,000 in 1980 could expect to live about 25 percent fewer years than people whose family income was greater than $50,000. We explore this finding using both individual data and a panel of aggregate birth cohorts observed from 1975 to 1995. We assume that...

Poverty counts are counts of individuals in poverty but are calculated from household or family data on income or expenditure. The transition from one to the other requires assumptions about intrahousehold allocation, about differences in needs across different people, and about the extent of...

We show that standard models of intertemporal choice, including the permanent income hypothesis, imply that for any given cohort of people born at the same time, inequality in both consumption and income will grow with age. At any given date, each individual's consumption depends on the integral...

Currency fluctuations provide a substantial source of movements in relative prices that is largely exogenous to the firm. This paper evaluates empirically and theoretically the importance of exchange rate movements on job reallocation across and within sectors. The objective is (1) to provide...

This paper examines whether the observed cross-country correlation between aggregate saving rates and economic growth can be explained by models in which higher growth increases saving rates, rather than the other way around. The paper focusses on two explanations of why growth might increase...

In this essay, I review Robert Fogel's The Escape from Hunger and Premature Death, 1700-2100 which is concerned with the past, present, and future of human health. Fogel's work places great emphasis on nutrition, not only for the history of health, but for explaining aspects of current health,...

Disease has traveled with goods and people since the earliest times. Armed globalization spread disease, to the extent of eliminating entire populations. The geography of disease shaped patterns of colonization and industrialization throughout the now poor world. Many see related threats to...

The extent to which growth reduces global poverty has been disputed for 30 years. Although there is better data than ever before, controversies are not resolved. A major problem is that consumption measured from household surveys, which is used to measure poverty, grows less rapidly than...
