We use unique data characterizing individual savings for twins and non-twins in urban China to examine why the savings rates of the young are elevated relative to the middle-aged, despite rising individual life-cycle incomes. We show that inter-generational co-residence masks the true life-cycle...

In many countries of the world the co-residence of young adults aged 25-34 with their parents is not uncommon and in some countries the savings rates of these age groups exceed those of the middle-aged contrary to the standard model of life-cycle savings. In this paper we examine the role of...

Obesity is an important global health problem. Although obesity is not directly related to access to health care or constrained by resource deprivation, overweight status is predominantly found in poor, less-educated populations. This paper seeks to identify the causal role of schooling in...

An open question in the literature is whether families compensate or reinforce the impact of child health shocks. Discussions usually focus on one dimension of child investment. This paper examines multiple dimensions using household survey data on Chinese child twins whose average age is 11. We...

A unique survey of Shanghai residents in 1996 that combined labor-market information, appraisals of respondents' beauty, and household expenditures allows us to examine the relative magnitudes of the investment and consumption components of women's spending on beauty-enhancing goods and...

This paper estimates the effects of maternal malnutrition exploiting the 1959-1961 Chinese famine as a natural experiment. In the 1% sample of the 2000 Chinese Census, we find that fetal exposure to acute maternal malnutrition had compromised a range of socioeconomic outcomes, including:...

In this paper, we define "The Chinese Saving Puzzle" as the persistently high national saving rate at 34-53 percent of gross domestic product (GDP) in the past three decades and a surge in the saving rate by 11 percentage points from 2000-2008. Using data from the Flow of Funds Accounts (FFA)...

We look at the effects of rainfall forecasts and realized rainfall on equilibrium agricultural wages over the course of the agricultural production cycle. We show theoretically that a forecast of good weather can lower wages in the planting stage, by lowering ex ante out-migration, and can...

We examine the generalizability of internally valid estimates of causal effects in a fixed population over time when that population is subject to aggregate shocks. This temporal external validity is shown to depend upon the distribution of the aggregate shocks and the interaction between these...

This paper examines the hypothesis that the persistence of low spatial and marital mobility in rural India, despite increased growth rates and rising inequality in recent years, is due to the existence of sub-caste networks that provide mutual insurance to their members. Unique panel data...
