In 2020, local governments in China began issuing digital coupons to stimulate spending in targeted categories such as restaurants and supermarkets. Using data from a large e-commerce platform and a bunching estimation approach, we find that the coupons caused large increases in spending of...

Does international trade affect the growth of cities, and vice versa? Assembling disaggregate data for four countries, we document a novel stylized fact: Export activity is disproportionately concentrated in larger cities - even more so than overall economic activity. We rationalize this fact by...

Research on centralized school assignment mechanisms often focuses on whether parents who participate in specific mechanisms are likely to truthfully report their preferences or engage in various costly strategic behaviors. However, a growing literature suggests that parents may not know enough...

We document novel survey-based facts on preferred long-run inflation rates among U.S. consumers. Consumers on average prefer a 0.20% annual inflation rate, considerably below the Federal Reserve's 2% target. Inflation preferences not only correlate with demographic and socioeconomic...

We examine the labor supply impact of a 2016 policy that allows retirement-eligible individuals covered by Peru's private pension system to receive retirement benefits as a lump sum rather than as an annuity. We present a theoretical model predicting that, for liquidity constrained workers, the...

We present an approach for automatically generating and testing, in silico, social scientific hypotheses. This automation is made possible by recent advances in large language models (LLM), but the key feature of the approach is the use of structural causal models. Structural causal models...

Social protection programs have become increasingly widespread in low- and middle-income countries, with their own distinct characteristics to match the environments in which they are operating. This paper reviews the growing literature on the design and impact of these programs. We review how...

We create a dataset of 14,000 hand-coded help-wanted advertisements placed by employment agencies in three U.S. newspapers in 1950 and 1960, a time when help-wanted advertisements were divided into male and female sections, and collect information on agency ownership. We find that female-owned...

We examine the long transition from water to steam power in US manufacturing, focusing on early users of mechanical power: lumber and flour mills. Digitizing Census of Manufactures manuscripts for 1850 to 1880, we show that as steam costs declined, manufacturing activity grew faster in counties...

We examine the impacts of ethical declarations on market transactions through a controlled laboratory experiment, where privately-informed sellers issue a public report prior to a first-price auction. We find that while signing an ethical statement does not reduce misreporting by sellers, it...
