Rising Mortality and Life Expectancy Differentials by Lifetime Earnings in the United States

Are mortality and life expectancy differences by socioeconomic groups increasing in the United States? Using a unique data set matching high-quality administrative records with survey data, this study explores trends in these differentials by lifetime earnings for the 1983 to 2003 period. The results indicate a consistent increase in mortality differentials across sex and age groups. The study also finds a substantial increase in life expectancy differentials: the top-to-bottom quintile premium increased around 30 percent for men and almost doubled for women. These results complement recent research to point to almost five decades of increasing differential mortality in the United States.Differential mortality, Life expectancy, Lifetime earnings, Trends

Entry and Quality Choices in Child Care Markets

Many developing countries have adopted the market approach for expanding the supply of child care, but little is known about the economic behavior of independent providers. This paper draws on uniquely rich administrative data on child care centers and their inputs from São Paulo to examine the role of local household income in shaping the entry and quality choices of private suppliers. It documents three main facts: (1) entry rates are considerably higher in high-income districts; (2) the quality of provision as measured by teachers’ schooling, group size and equipment is highly heterogeneous across space and increases systematically with local household income; and (3) a considerable share of centers operates below recommended (but not regulated) quality standards, especially in low-income districts. These findings accord with a model in which heterogeneous providers optimally adjust the quality of care to the willingness to pay for quality of local consumers. Market-driven heterogeneity in the quality of provision across space is a key consideration for understanding the effect of regulations on the supply of child care.Child care markets, Entry, Product quality, Minimum quality standards

Does Energy Consumption Respond to Price Shocks? Evidence from a Regression-Discontinuity Design

This paper exploits unique features of a recently introduced tariff schedule for natural gas in Buenos Aires to estimate the short-run impact of price shocks on residential energy utilization. The schedule induces a non-linear and nonmonotonic relationship between households’ accumulated consumption and unit prices, thus generating an exogenous source of variation in perceived prices, which is exploited in a regression-discontinuity design. The estimates reveal that a price increase in the utility bill received by consumers causes a substantial and prompt decline in gas consumption. Hence they suggest that policy interventions via the price mechanism, such as price caps and subsidies, are powerful instruments to influence residential energy utilization patterns, even within a short time span.Energy consumption, Elasticity of demand, Regulation of public utilities, Regression discontinuity design, Public policy

Affecting Children and the Effect of Children

In the first half of my dissertation, I estimate the causal effect of a first child on female labor supply. This is a difficult task given the endogeneity of the fertility decision. Ideally, this question could be answered by running a social experiment where women are randomly assigned children or not. Using field data from the National Survey of Family Growth (NSFG), I mimic this hypothetic experiment by focusing on a sample of women that sought help to become pregnant. After a certain period since they started receiving help, only some of these women are successful. In this instance, fertility appears to be exogenous to labor supply in that pre-treatment labor supply is uncorrelated with subsequent fertility. Using this strategy, I estimate that having a first child younger than a year old reduces female labor supply by 26.3 percentage points. These estimates are close to OLS and fixed-effects estimates obtained from a panel data constructed from the NSFG. They are also close to OLS estimates obtained using similarly defined samples from the 1980 and 1990 Censuses. The second part of my dissertation explores the problem of an educational authority who decides his revelation policy about students' educational attainments in order to maximize mean educational achievement. Incentives in an educational context are different from those in the marketplace. Schools cannot pay students to motivate them to attain higher levels of education. However, there is still a role for incentives. Since students care about which signal they can get from the school (pass/fail, GPA), the school has a tool to influence students' behavior. Using a theoretical model, I explore the optimal way to use this tool, i.e., the optimal way to reveal educational achievements. I find that this optimal revelation policy is dependent on the distribution of students with respect to ability. I show that this optimal scheme could be: a) classify individuals in two groups and just reveal this information, b) reveal all information, c) set a critical standard and group all individuals together below this level and provide full information about students' productivity above it
