摘要：We examine how physician decisions are affected by difficult cases-encounters with newly diagnosed cancer patients. Using detailed administrative data, we compare primary care physicians' decisions in visits that occurred before and after difficult cases and matched comparison cases by the same physicians on other dates. Immediately following a difficult case, physicians increase referrals for common tests, including diagnostic tests unrelated to cancer. The effect lasts only for about an hour...

摘要：We investigate how exposure to the One-Child Policy (OCP) during early adulthood affects marriage and fertility in China. Exploring fertility penalties across provinces over time and the different implementations by ethnicity, we show that the OCP significantly increases the unmarried rate among the Han ethnicity but not among the minorities. The OCP increases Han-minority marriages in regions where Han-minority couples are allowed an additional child, but the impact is smaller in other region...

摘要：I introduce a simple permutation procedure to test conventional (nonsharp) hypotheses about the effect of a binary treatment in the presence of a finite number of large, heterogeneous clusters when the treatment effect is identified by comparisons across clusters. The procedure asymptotically controls size by applying a level-adjusted permutation test to a suitable statistic. The adjusted permutation test is easy to implement in practice and performs well at conventional levels of significance...

摘要：We conduct a field experiment with low-income shoppers to study how behavioral interventions can improve the effectiveness of healthy food subsidies. Our unique design enables us to deliver subsidies both before and during grocery shopping. We examine the effects of two nonrestrictive changes to the choice environment: giving shoppers agency over the subsidy they receive and introducing a waiting period before a subsidized shopping trip to prompt deliberation about upcoming purchases. These in...

摘要：During the early part of the COVID-19 pandemic, national andlocal governments introduced a number of policies to combat the spread ofCOVID-19. In this paper, we propose a new approach to bound the effectsof such early-pandemic policies on COVID-19 cases and other outcomeswhile dealing with complications arising from (i) limited availability ofCOVID-19 tests, (ii) differential availability of COVID-19 tests acrosslocations, and (iii) eligibility requirements for individuals to be tested. Weuse ...

摘要：This paper examines the impacts of technology training and buyer-supplier relationship on technology adoption and quality upgrading. We randomly varied subjects of each training group across farmer-exporter clusters-farmers, exporters, both, or none-and provided training on Good Agricultural Practices (GAP). We find that training farmers enhances technology adoption and quality upgrading. Yet, the effects are much stronger when farmers and exporters are trained together. We document a plausibl...

摘要：I propose a new method of identifying firms' subjective beliefs in dynamic models. In settings where actions are continuous and substitutable in contributing to an endogenous state, I show how beliefs about exogenous state transitions can be separately identified from static payoffs. Applying this method to identifying beliefs about future SO2 allowance prices in the U.S. Acid Rain Program, I find that electric utilities underestimate the movements in the allowance price, leading to compliance...

摘要：We experimentally examine how individuals commit to a cutoff stopping rule when facing a sequence of independent lotteries. We identify two main behavior patterns: (a) a small share of participants consistently choose stopping rules whose gain bound (i.e., the accumulated gain at which the sequence stops) is larger than the loss bound, and (b) a larger share of participants consistently choose rules whose loss bound is larger than the gain bound. We introduce a procedural choice model that acc...

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 ...
