摘要：We highlight a lesser-known consequence of China's integration into the world economy: the rise of services trade. We demonstrate how the United States' trade deficit in goods cycles back as a surplus in U.S. exports of education services. Focusing on China's accession to the World Trade Organization, we show that Chinese cities more exposed to trade liberalization sent more students to U.S. universities. Growth in housing income and wealth allowed Chinese families to afford U.S. tuition, and ...

摘要：Allocations decisions are vulnerable to political influence, but it is unclear in which situations politicians use their discretionary power in a partisan manner. We analyze the allocation of presidential disaster declarations in the United States, exploiting the spatiotemporal randomness of all hurricane strikes from 1965 to 2018 along with changes in political alignment. We show that decisions are unbiased when disasters are either very strong or weak. Only after medium-intensity hurricanes ...

摘要：This paper analyzes private antifraud enforcement under the False Claims Act, which compensates whistleblowers for litigating against health care providers who overbill the US government. I conduct several case studies of successful whistleblower lawsuits concerning Medicare fraud, pairing new legal data with large samples of Medicare claims. I estimate that deterrence from $1.9 billion in whistleblower settlements generated Medicare cost savings of nearly $19 billion, while imposing low costs...

摘要：In a field experiment among 9,823 customers of the Namibian water utility, we implement interventions to reduce nonpayments. The interventions are based on diagnostic surveys to identify key obstacles to payments. They address informational frictions and apply psychological commitment techniques to narrow the gap between customers' willingness to pay and actual payments. Initially, payments increase by 29% to 55%, making the interventions highly cost-effective. Removing informational frictions...

摘要：Many agricultural and environmental technologies require up-front investments. This may deter adoption, particularly in settings characterized by information, liquidity, and credit constraints. We test for these barriers to the adoption of an agricultural technique that helps address land degradation in Niger. We find little evidence that liquidity or credit constraints deter adoption: instead, providing farmers with training increasesthe share of adopters by over 90 percentage points. Conditi...

摘要：We highlight that analyses using interaction terms to study treatment effect heterogeneity are susceptible to a form of omitted variable bias that is often overlooked in economics. Unlike most instances of omitted variable bias, the omitted variables in this case are available to the researcher but were not included in the model. We demonstrate that this exclusion matters based on a replication of 205 estimates across seventeen papers published in the American Economic Review over a five-year ...

摘要：We provide direct evidence on explicit and implicit biases against women among students in economics relative to other fields. We conducted a large scale survey among undergraduates in Chile, among both entering first-year students and students in years 2 and above, combining a wide battery of measures to create an index of gender bias. Economics students are more biased than students in other fields. There is some evidence that economics students are more biased already upon entry, before exp...

摘要：This paper provides the first evidence from a randomized controlled trial isolating the impact of financial assistance to prevent homelessness. In this study, individuals and families at imminent risk of homelessness were offered temporary financial assistance, averaging nearly $2,000 for those assigned to treatment. Our results show that this assistance significantly reduces homelessness by 3.8 percentage points from a base rate of 4.1%. The effects are larger for people with a history of hom...

摘要：This paper identifies productivity gains from trade by studyingthe manipulation behavior of firms in response to regulatory policies oninternational trade in China. Bunching estimates show that participationin international trade increases firm productivity. The productivity gainsincrease over time, indicating dynamic learning from trading. Further exploration shows no effects on R&D investment, product rationalization,and markup. Young firms and nonstate-owned firms (non-SOEs) gain morefrom p...
