I estimate the effects of collaborative and adversarial intergroup contact. I randomly assigned Indian men from different castes to participate in cricket leagues or to serve as a control group. League players faced variation in collaborative contact, through random assignment to...

While World War II (WWII) is often employed as natural experiment to identify long-term effects of adverse early-life and prenatal conditions, little is known about the short-term effects. We estimate the short-term impact of the onset of WWII on newborn health using a unique data set of...

This paper empirically investigates the long-run effects of major health improvements on income growth in the United States. To isolate exogenous changes in health, the econometric model uses quasi-experimental variation in cardiovascular disease mortality across states over time. The results...

We document systematic and significant time variation in US lifecycle non-durable consumption profiles. Consumption profiles have consistently become flatter: differences in consumption across generations have decreased. Pooling data across different periods to identify lifecycle profiles masks...

Using a long-panel dataset of Japanese firms that contains firm-level sales forecasts, we provide evidence on firm-level uncertainty and imperfect information over their life cycle. We find that firms make non-negligible and positively correlated forecast errors. However, they make more precise...

We construct and estimate an economic model of religious giving. We employ a dynamic consumer optimization model with mortality in which intra-temporal utility stems from both consumption and religious contributions. Individuals also decide how to allocate resources between religious...

Adverse economic shocks occur frequently and may cause individuals to reevaluate key life decisions in ways that have lasting consequences for themselves and the economy. These life decisions are fundamentally tied to specific periods of an individual’s career, and economic shocks may...

Most economic models assume that time preferences are stable over time, but the evidence on their long-term stability is lacking. We study whether and how time preferences change over the life cycle, exploiting representative long-term panel data. We provide new evidence that discount rates...

Labor markets are characterized by large heterogeneity in job stability. Some workers hold lifetime jobs, whereas others cycle repeatedly in and out of employment. This paper explores the economic consequences of such heterogeneity. Using Survey of Consumer Finances (SCF) data, we document a...
