摘要：Using microdata from the American Red Cross (ARC) and the Federal Election Commission (FEC) in two natural experiments, we provide evidence that political giving and charitable giving are substitutes. In the first natural experiment, we estimate the effects of a positive shock to charitable donations to the ARC: foreign natural disaster events. We find that although charitable donations to ARC increase by 34.9% in the six weeks following a disaster, political donations decline by 18.8% in the ...

摘要：We investigate the participation and effectiveness of paid endorsers in sponsored tweet campaigns. We manipulate the financial pay rate offered to endorsers on a Chinese paid endorsement platform, where payouts are contingent on participation rather than engagement outcomes. Hence, our design can distinguish between variation in participation and variation in outcomes, even if people select to endorse only specific tweets. Also, the lack of compensation for effort allows one to attribute diffe...

摘要：This paper compares two estimators-the Border Approach and an Instrumental Variable (IV) estimator-using a unified framework where identifying variation arises from preference externalities, following the intuition in Waldfogel (2003). We highlight two dimensions in favor of the IV approach. First, an econometric model of the data-generating process reveals that the border approach requires a set of identification assumptions that are not easily satisfied in practice: the ignorance of some pay...

摘要：Retailers face increasing competitive pressure to determine how best to deliver products purchased online to the end customer. Grocery retailers often require attended home delivery where the customer must be present to receive the delivery. For attended home delivery to function, the retailer and customer must agree on a delivery time slot that works for both parties. Using online data from a grocery retailer, we observe customer preferences for three delivery service attributes associated wi...

摘要：We introduce a measure of regret for stock market investors and investigate its cross-sectional asset pricing implications. According to our regret-based framework, investors experience regret due to not achieving the highest possible return from a similar set of stock investments, and equity portfolios with high regret generate 6.84% more annualized alpha than portfolios with low regret. Using investor-trading activity of 78,000 households at a large U.S.-based brokerage firm, we develop an i...

摘要：Revealed preferences between alternatives can be systematically reversed across a variety of elicitation procedures (e.g., choice, valuation, matching, joint/separate evaluation). These puzzling findings have been usually invoked to challenge the procedure invariance principle. Yet procedure -dependent preferences can be endogenous. This paper presents a unifying theory of contextual deliberation to account for seemingly disparate phenomena of preference reversals. When attribute importance is...

摘要：Continuity of care, defined as an ongoing therapeutic relationship between a patient and a physician, is a defining characteristic of primary care. However, arranging a consultation with one's regular doctor is increasingly difficult as practices face physician shortages. We study the effect of declining care continuity on the productivity of physicians by analyzing data of over 10 million consultations in 381 English primary care practices over a period of 11 years. Specifically, we examine w...

摘要：This paper examines the causal relationship between proximity and knowledge diffusion by estimating the elasticity of core-based statistical area (CBSA) pair-level citations to variations in travel time induced by the introduction of new flight routes. The findings reveal that decreasing travel time between U.S. cities by 20% increases knowledge flow by 0.5%, which corresponds to an increase of over 15,000 citations at the aggregate level. Rather than boosting within-firm knowledge transfer, t...

摘要：Data brokers use black -box methods to profile and segment individuals for ad targeting, often with mixed success. We present evidence from 5 complementary field tests and 15 data brokers that differences in profiling accuracy and coverage for these attributes mainly depend on who is being profiled. Consumers who are better off-for example, those with higher incomes or living in affluent areas-are both more likely to be profiled and more likely to be profiled accurately. Occupational status (w...

摘要：We study the comparative advantage of firms with focused and multidivisional organizational forms at attracting valuable human capital. Using the merger and acquisition (M&A) advisory industry as a laboratory, we show that high-performing individuals are more likely to migrate to boutique (focused) banks, especially those who are still on the upward trajectory of their career. Such migration is amplified by the cross-subsidization inside bulge bracket (multidivisional) firms, proxied by poor p...
