摘要：We consider a distribution system in which retailers replenish perishable goods from a warehouse, which, in turn, replenishes from an outside source. Demand at each retailer depends on exogenous features and a random shock, and unfulfilled demand is lost. The objective is to obtain a data -driven replenishment and allocation policy that minimizes the average inventory cost per time period. The extant datadriven methods either cannot guarantee a feasible solution for out -of -sample feature obs...

摘要：This paper studies how online grocers use service time to respond to local competition and demand conditions when prices are uniformly set at the national level. Using comprehensive data collected twice a week over three years from 172 Israeli local markets, we show that an online grocer sets identical prices in all markets. By contrast, service time is shorter in more competitive markets and on low-demand days. Next, we exploit regional and temporal variation in entry decisions to examine how...

摘要：We examine how information processing costs affect the extent to which depositors' use the details in banks' income statements. Depositors have a unique cost-benefit structure because they are nonprofessional users of financial information and have high information processing costs. At the same time, they benefit from acting quickly because failing banks make payments on a first-come, first-serve basis. This makes it likely that they will react to a prominent summary measure like the reported ...

摘要：Regulatory stress tests have become one of the main tools for setting capital requirements at the largest U.S. banks. The Federal Reserve uses confidential models to evaluate bank-specific outcomes for bank-specific portfolios in shared stress scenarios. As a matter of policy, the same models are used for all banks, despite considerable heterogeneity across institutions; individual banks have contended that some models are not suited to their businesses. Motivated by this debate, we ask, what ...

摘要：Would consumers be willing to pay more for goods for which there is less inequality in wages across those involved in their production? In incentive-compatible behavioral choice studies on representative samples of the English and U.S. populations, we find significantly positive willingness to pay for such inequality reductions in more than 80% of subjects. Although it varies with political leaning and the extent of the inequality reduction, willingness to pay is positive across the political ...

摘要：Modern traceability technologies promise to improve supply chain management by simplifying recalls, increasing visibility, and verifying sustainable supplier practices. Initiatives leading the implementation of traceability technologies must choose the least-costly set of firms-or seed set-to target for early adoption. Choosing this seed set is challenging because firms are part of supply chains interlinked in complex networks, yielding an inherent supply chain effect: benefits obtained from t...

摘要：Advertising is a crucial revenue source for e -commerce platforms and a vital online marketing tool for their sellers. In this paper, we explore dynamic ad allocation with limited slots upon each customer's arrival for an e -commerce platform, where customers follow a choice model when clicking the ads. Motivated by the recent advocacy for the algorithmic fairness of online ad delivery, we adjust the value from advertising by a general fairness metric evaluated with the click-throughs of diffe...

摘要：We document a novel platform effect caused by the emergence of fintech platforms in the intermediation of financial products. In China, platform distributions of mutual funds emerged in 2012 and grew quickly into a formidable presence. Utilizing the staggered entrance of funds onto platforms, we find a marked increase of performance chasing driven by the centralized information flow unique to fintech platforms. This pattern is further confirmed using proprietary data from a top platform. Exami...

摘要：Accounting standards prohibit internally created knowledge and organizational capital from being disclosed on firm balance sheets. As a result, balance sheets exhibit downward biases that have become exacerbated by increasing levels of intangible investments. To offset these biases, researchers must estimate the value of these off -balance sheet intangibles by capitalizing prior flows of research and development (R&D) and selling, general, and administrative (SG&A). In doing so, a set of capit...

摘要：While patents have been shown to play a role as barriers to entry, they also reveal information about incumbent strategies and risk being invalidated. We examine the trade-off incumbents face between using their patents ex ante as entry deterrents or ex post once competitors have revealed their moves. Leveraging the unique characteristics of the pharmaceutical sector, in which it is possible to observe exactly when a competitor entry threat materializes, and exploiting exogenous variation in t...
