摘要：Consumer data increasingly enable online marketplaces to identify buyers' preferences and provide individualized product information. Buyers, however, fully learn their product value only after contracting, when the product is delivered. I characterize the impact of such ex ante information on buyer surplus and seller surplus, when the seller sets prices and refund conditions in response to the ex ante information. I show that efficient trade and an arbitrary split of the surplus can be achiev...

摘要：In his work on economic development, Lucas's goals were to understand the enormous diversity across countries in levels and growth rates of per capita income and to build a framework for studying developing economies with the same kind of precision and rigor that the neoclassical growth model had brought to the study of already industrialized countries. Lucas found knowledge spillovers to be a key mechanism. Thus, human capital, which he viewed broadly, is at the center of much of his work, an...

摘要：We study the effectiveness of pay-and-chase lawsuits and up-front regulations for combating health-care fraud. Between 2003 and 2017, Medicare spent $7.7 billion on 37.5 million regularly scheduled ambulance rides for patients traveling to and from dialysis facilities even though many did not satisfy Medicare's criteria for receiving reimbursements. Using an identification strategy based on the staggered timing of regulations and lawsuits across the United States, we find that adding a prior a...

摘要：We propose a political economy mechanism that explains the presence of fiscal regimes punctuated by crisis periods. Our model focuses on the interaction between successive deficit-biased governments subject to independently and identically distributed fiscal shocks. We show that the economy transitions between a fiscally responsible regime and a fiscally irresponsible regime, with transitions occurring during crises when fiscal needs are large. Under fiscal responsibility, governments limit th...

摘要：We estimate long-run trends in intergenerational relative mobility for representative samples of the US-born population. Harmonizing all surveys that include father's occupation and own family income, we develop a mobility measure that allows for the inclusion of nonwhite individuals and women for the 1910s-1970s birth cohorts. We show that mobility increases between the 1910s and 1940s cohorts and that the decline of Black-white income gaps explains about half of this rise. We also find that ...

摘要：This paper implements a field experiment in India to study whether the effects of religious diversity on productivity and attitudes depend on a firm's production technology. I randomly assigned Hindu and Muslim workers at a manufacturing plant in West Bengal to mixed or homogeneous teams. Production tasks are categorized as high or low dependency based on the degree of continuous coordination required. Mixed teams are less productive than homogeneous teams in high-dependency tasks, but this ef...

摘要：We develop a generalized theory of rationed fertility to analyze treatment effect heterogeneity in the child quantity-quality trade-off. An exogenous increase in fertility can be either desired or undesired. We derive a positive rationing income effect on child quality for desired fertility increases but a negative rationing income effect for undesired fertility increases. We propose an econometric framework to identify treatment effects of desired and undesired fertility increases and estimat...

摘要：We conduct experiments on an online platform to investigate the causal effect of gender discrimination on labor supply decisions. Controlling for the piece-rate wage, we find that workers who face explicit negative gender-discriminatory wage inequality supply substantially less labor compared with workers who face gender-neutral wage inequality. We also examine the effect of positive discrimination, differences between men and women, and the impact of implicit rather than explicit discriminati...

摘要：I develop a quantitative theory of bilateral trade agreements with intellectual property (IP) provisions in a multicountry growth model. The model's dynamics are driven by innovation and technology licensing. Imperfect IP enforcement leads to reduced royalty payments and growth. Governments negotiate tariffs and IP enforcement through Nash bargaining. Gains from the trade agreement vary along the transition. Developing countries experience short-term losses, while developed countries gain in b...

摘要：We study how regulating data usage impacts innovation in digital markets. Platforms commonly use proprietary data about third-party sellers to inform their own competing offerings, dampening incentives for innovation. We model this interaction and characterize how data usage restrictions reshape these incentives. An outright ban on data usage may boost or curtail innovation, depending on the thickness of the right tail of demand for new products. More flexible rules controlling when and what d...
