摘要：The Centers for Medicare & Medicaid Services (CMS) and the National Quality Forum have endorsed the 30-day mortality rate as an important indicator of hospital quality. Concerns have been raised, however, as to whether postdischarge mortality rates are reasonable measures of hospital quality as they consider the frequency of an event that occurs after a patient is discharged and is no longer under the watch and care of hospital staff. Estimating the causal effect of length of stay (LOS) on pos...

摘要：Dynamic pricing through price promotions has been widely used by online retailers. We study how a promotion strategy, one that offers customers a discount for products in their shopping cart, affects customer behavior in the short and long term on a retailing platform. We conduct a randomized field experiment involving more than 100 million customers and 11,000 retailers with Alibaba Group, one of the world's largest retailing platform. We randomly assign eligible customers to either receive p...

摘要：This paper studies an inventory management problem faced by an upstream supplier that is in a collaborative agreement, such as vendor-managed inventory (VMI), with a retailer. A VMI partnership provides the supplier an opportunity to manage inventory for the supply chain in exchange for point-of-sales (POS)- and inventory-level information from the retailer. However, retailers typically possess superior local market information and as has been the case in recent years, are able to capture and ...

摘要：We consider the use and value of social-network information in selectively selling goods and services whose value derives from exclusive ownership among network connections or friends. Our model accommodates customers who are heterogeneous in their number of friends (degree) and their proclivity for social comparisons (conspicuity). Firms with information on either (or both) of these characteristics can use it to make the product selectively available and to personalize prices. We find that fi...

摘要：We are the first to document and study the use of Rule 10b5-1 preset repurchase plans. Though the rule's original intent was to clarify conditions for enforcing insider trading laws, generally thought to apply to individuals classified as firm insiders, we find strong use of the rule at the firm level to repurchase company stock. We exploit this new and widespread form of payout to examine an issue at the core of payout decisions-the trade-off between commitment and financial flexibility. Rela...

摘要：Platforms create value by matching participants on alternate sides of the marketplace. Although many platforms practice one-to-one matching (e.g., Uber), others can conduct and monetize one-to-many simultaneous matches (e.g., lead-marketing platforms). Both formats involve one dimension of private information, a participant's valuation for exclusive or shared allocation, respectively. This paper studies the problem of designing an auction format for platforms that mix the modes rather than lim...

摘要：We investigate how firms can use the results of field experiments to optimize the targeting of promotions when prospecting for new customers. We evaluate seven widely used machine-learning methods using a series of two large-scale field experiments. The first field experiment generates a common pool of training data for each of the seven methods. We then validate the seven optimized policies provided by each method together with uniform benchmark policies in a second field experiment. The find...

摘要：We study compatibility decisions of two competing platform owners that generate profits through both hardware sales and royalties from content sales. We consider a game-theoretic model in which two platforms offer different standalone utilities to users. We find that incentives to establish one-way compatibility-the platform owner with smaller standalone value grants access to its proprietary content application to users of the competing platform-can arise from the difference in their profit f...

摘要：Levy [Levy H (2016) Aging population, retirement, and risk taking. Management Sci. 62( 5):1415-1430] argues that the portfolio with the maximal geometric mean (MGM) asymptotically dominates any other portfolio; that is, as the investment horizon becomes very long, the MGM portfolio is preferred over any other portfolio for all preferences with marginal utility bounded from above, U' <= M. The important economic implication is that in the long run, an all-equity portfolio dominates bond (or mix...

摘要：We study a setting in which dynamically arriving items are assigned to waiting agents, who have heterogeneous values for distinct items and heterogeneous outside options. An ideal match would both target items to agents with the worst outside options and match them to items for which they have high value. Our first finding is that two common approaches-using independent lotteries for each item and using a waitlist in which agents lose priority when they reject an offer-lead to identical outcom...
