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：We examine how investors' investment judgments are jointly affected by two important linguistic features that vary considerably across firms' risk factor disclosures: namely, causal focus-the extent to which managers' disclosures focus on the causes versus consequences of risk events-and specificity, which refers to specific references to names of objects and quantitative values. Results of controlled experiments show that, when the disclosure focus is on risk causes, greater specificity incre...

摘要：This paper examines a grocery retailer's management of a premade food product. The retailer's goal is to maximize a weighted sum of direct profit and customer welfare. Multiple items of the product are produced in batches and immediately displayed for sale. Considering that each item's quality decreases while it sits on the shelf, the retailer chooses the shelf life, whether to issue items in first-in-first-out (FIFO) or last-in-first-out (LIFO) order, whether to timestamp items, and how to pr...

摘要：Motivated by the human-machine interaction such as recommending videos for improving customer engagement, we study human-guided human-machine interaction for decision making with private information. We model this interaction as a two-player turnbased game, where one player (Bob, a human) guides the other player (Alice, a machine) toward a common goal. Specifically, we focus on offline reinforcement learning (RL) in this game, where the goal is to find a policy pair for Alice and Bob that maxi...

摘要：This paper presents a comprehensive analysis of traditional versus selective hedging strategies in commodity futures markets. Traditional hedging aims solely to reduce spot price risk, whereas selective hedging also seeks to enhance returns by predicting movements in commodity futures prices. We construct selective hedges using a range of forecasting techniques, from simple historical averages to advanced machine learning models, and evaluate their performance based on the expected mean-varian...

摘要：Producing high-quality content through open knowledge collaboration presents a dilemma. Successful quality control requires rejecting contributions that do not align with the aims of an open knowledge collaboration system, yet rejections demotivate new contributors from attempting further contributions. Building on research on the regulation of behavior in online communities and on organizational selection, we theorize how the way rejections are communicated affect new contributors. We leverag...
