摘要：We study how to reduce congestion in two-sided matching markets with private preferences. We measure congestion by the number of bits of information that agents must (i) learn about their own preferences, and (ii) communicate with others before obtaining their final match. Previous results suggest that a high level of congestion is inevitable under arbitrary preferences before the market can clear with a stable matching. We show that when the unobservable component of agent preferences satisfi...

摘要：In the wake of the 2016 U.S. presidential election, social-media platforms are facing increasing pressure to combat the propagation of fake news (i.e., articles whose content is fabricated). Motivated by recent attempts in this direction, we consider the problem faced by a social-media platform that is observing the sharing actions of a sequence of rational agents and is dynamically choosing whether to conduct an inspection (i.e., a fact-check) of an article whose validity is ex ante unknown. ...

摘要：We consider a periodic-review, single-product inventory system with lost sales and positive lead times under censored demand. In contrast to the classical inventory literature, we assume the firm does not know the demand distribution a priori and makes an adaptive inventory-ordering decision in each period based only on the past sales (censored demand) data. The standard performance measure is regret, which is the cost difference between a learning algorithm and the clairvoyant (full-informati...

摘要：The United States is in the midst of a drug overdose epidemic. Although the online availability of drugs has been a growing concern with considerable speculation that digital platforms are contributing to this epidemic, empirical assessments have been lacking. To quantify this impact, we rely on the phased rollout of Craigslist, a major online platform, as an experimental setup. Applying a difference-in-differences approach on a national panel data set for all counties in the United States fro...

摘要：This paper examines how media rankings shift patterns of collaboration and deference between professional groups within organizations. Diversified and multidisciplinary organizations such as universities and hospitals often face distinct subunit evaluations that can influence coordination on interdependent tasks. Using patient-level treatment data for more than five million in-patient stays, I find that changes in the best hospitals rankings do not meaningfully shift treatment patterns by phys...

摘要：Technology and intellectual property play increasingly critical roles in emerging supply chains by endowing products with sought-after capabilities. In such technology-intensive supply chains, the technology invented by an upstream firm must be embedded in a subsystem that is then integrated into apt! system. The technology providers' prevalent royalty-driven business model has gotten complicated in this multilateral supply chain, prompting formal research attention. Moreover, providers also c...

摘要：Standard auction formats feature either an upper bound on the equilibrium price that descends over time (as in the Dutch auction) or a lower bound on the equilibrium price that ascends over time (as in the English auction). We show that in some settings with costly information acquisition, auctions featuring both (viz., a narrowing channel of prices) outperform the standard formats. This Channel auction preserves some of benefits of both the English (truthful revelation) and Dutch (security fo...

摘要：Just as employers face uncertainty when hiring workers, workers also face uncertainty when accepting employment, and bad employers may opportunistically depart from expectations, norms, and laws. However, prior research in economics and information sciences has focused sharply on the employer's problem of identifying good workers rather than vice versa. This issue is especially pronounced in markets for gig work, including online labor markets, in which platforms are developing strategies to h...

摘要：A growing number of firms use incentive programs to encourage healthy behaviors, but there is little evidence about how such incentives should be structured over time. We explore this issue using a large field experiment that incentivized employees of a Fortune 500 company to use their workplace gym. We compare the effectiveness of a treatment with constant incentives over 8 weeks to two treatments that varied incentives over time. One variable treatment featured front-loaded incentives, which...

摘要：We develop a model in which reward-based crowdfunding enables firms to obtain a reliable proof of concept early in their production cycle: they learn about total demand from a limited sample of target consumers preordering a new product. Learning from the crowdfunding sample creates a valuable real option because firms invest only if updated expectations about total demand are sufficiently high. This is particularly valuable for firms facing a high degree of uncertainty about consumer preferen...
