We use detailed data from a large retail panel to study the effect of participation in Supplemental Nutrition Assistance Program (SNAP) on composition and nutrient content foods purchased for at-home consumption. find that SNAP is small relative cross-sectional variation most outcomes we consider. Estimates model relating household’s food purchases current level spending imply closing gap betwe...

OBJECTIVE Relatively little is known about how excess body mass affects adolescents' capacity to perform sustained exercise. We hypothesized that most of the difficulty that severely overweight adolescents have with sustained exercise occurs because the metabolic costs of moving excess mass result in use of a high proportion of their total oxygen reserve. METHODS We compared results from a ma...

We study the impact of group-based cognitive behavioral therapy (CBT ) for individuals selected from general population poor households in rural Ghana (N = 7,227). Results one to three months after program show strong impacts on mental and perceived physical health, socioemotional skills, economic self-perceptions. These effects hold regardless baseline distress. argue that this is because CBT ...

This paper studies, theoretically and experimentally, the effects of overconfidence fake news on information aggregation quality democratic choice in a common-interest setting. We show that exacerbates adverse widespread misinformation (i.e., news). then analyze richer models allow for partisanship, targeted intended to sway public opinion, signals correlated across voters (due media ownership ...

We study the impact of deliberation on intertemporal choices. Using multiple experiments, including a field in Democratic Republic Congo, we show that introduction waiting periods—a policy temporally separates information about choices from themselves—causes substantially less myopic decisions. These results cannot be captured by models exponential discounting nor present bias. Comparing effect...

Using a laboratory experiment, we identify whether decision-makers consider it mistake to violate canonical choice axioms. To do this, incentivize subjects report axioms they want their decisions satisfy. Then, make lottery choices which might conflict with axiom preferences. In instances of conflict, give the opportunity re-evaluate decisions. We find that many individuals follow and revise be...

We document heterogeneity in the marginal propensity to consume (MPC) across household characteristics relevant understanding heterogeneous agent models and monetary policy transmission. find a strong negative relationship between liquid wealth MPC. show that predicts MPC closely for every other characteristic we look at. use new empirical method overcomes sources of bias found existing literat...

Analyzing account-level data from an account aggregator, we find that households increase consumption when they receive expected tax refunds, as if face liquidity constraints. However, these same smooth making payments in other years, primarily by transferring funds among liquid accounts. Even carrying credit card debt payments, and even highly spend out of refunds. This behavior is inconsisten...
