摘要：Using a proprietary data set containing more than 10 million transactions over 14 months from hundreds of grocery stores, we examine consumer payment choices at point of sale (POS) between cash and mobile, where the use of other methods (including cards) is minimal. We find that cash is the dominant method of payment. Nonetheless, the share of mobile payments has increased at the expense of cash payments over time. Importantly, we exploit price incentives for consumers using mobile payment to ...

摘要：Problems concerning dynamic learning and decision making are difficult to solve analytically. We study an infinite-horizon discrete-time model with a constant unknown state that may take two possible values. As a special partially observable Markov decision process (POMDP), this model unifies several types of learning-and-doing problems such as sequential hypothesis testing, dynamic pricing with demand learning, and multiarmed bandits. We adopt a relatively new solution framework fromthe POMDP...

摘要：In this paper, we examine the impact of racially charged events on the demand for antiracist classroom resources in U.S. public schools. We use book requests made by teachers on DonorsChoose, the largest crowdfunding platform for public school teachers, as a measure of intent to address race-related topics in the classroom. We use the precise timing of high-profile police brutality and other racially charged events in the United States (2010-2020) to identify their effect on antiracism request...

摘要：We consider the periodic review dynamic pricing and inventory control problemwith fixed ordering cost. Demand is randomand price dependent, and unsatisfied demand is backlogged. With complete demand information, the celebrated (s, S, p) policy is proved to be optimal, where s and S are the reorder point and order-up-to level for ordering strategy, and p, a function of on-hand inventory level, characterizes the pricing strategy. In this paper, we consider incomplete demand information and devel...

摘要：We examine whether venture capital (VC) investors learn information contained in public market stock prices. VCs are less likely to stage finance startups and syndicate with other VCs when stock prices are more informative. An instrumental variable approach suggests that the relation is likely causal. The startup's initial public offering (IPO) prospect is the plausible information contained in stock prices learned by VCs. The effect of VC learning on staging and syndication is more pronounced...

摘要：This paper examines an innovative return policy, return insurance, emerging on various shopping platforms such as Taobao.com and JD.com. Return insurance is underwritten by an insurer and can be purchased by either a retailer or a consumer. Under such insurance, the insurer partially compensates consumers for their hassle costs associated with product return. We analyze the informational roles of return insurance when product quality is the retailer's private information, consumers infer quali...

摘要：Modern digital technology has enabled the emergence of the hybrid workforce in service organizations, where a firm uses on-demand freelancers to augment its traditional labor supply of employees. Freelancers are typically supplied by an electronic platform. How should demand be allocated between employees and freelancers? Under what conditions is the system(comprising the firm and its platform) sustainable in the long run? We investigate these questions in the context of last-mile delivery. We...

摘要：In social trading, less experienced investors (followers) are allowed to copy the trades of experts (traders) in real time after paying a fee. Such a copy-trading mechanism often runs into a transparency-revenue tension. On the one hand, social trading platforms need to release traders' trades as transparently as possible to allow followers to evaluate traders accurately. On the other hand, complete transparency may undercut the platform's revenue because followers can free ride. That is, foll...

摘要：This paper examines the behavior of job seekers and recruiters in the labor market for software engineers. I obtained data from a recruiting platform where individuals can self-report their computer programming skills and recruiters can message individuals they wish to contact about job opportunities. I augment this data set with measures of each individual's previous programming experience based on analysis of actual computer source code they wrote and shared within the open-source software c...

摘要：Cash flows to hedge funds are highly sensitive to performance streaks, a streak being defined as subsequent quarters during which a fund performs above or below a benchmark, even after controlling for a wide range of common performance measures. At the same time, streaks have limited predictive power regarding future fund performance. This suggests investors weigh information suboptimally, and their decisions are driven too strongly by a belief in continuation of good performance, consistent w...
