摘要：We consider the problem of choosing, from a set of N potential stock-keeping units (SKUs) in a retail category, K SKUs to be carried at each store to maximize revenue or profit. Assortments can vary by store, subject to a maximum number of different assortments. We view a SKU as a set of attribute levels and also model possible substitutions when a customer's first choice is not in the assortment. We apply maximum likelihood estimation to sales history of the SKUs currently carried by the reta...

摘要：The density, size, and location of stores in a retailer's network influences both the retailer's and the consumers' costs. With stores few and far between, consumers must travel a long distance to shop, whereas shopping trips are shorter with a dense network of stores. The layout of the retail supply chain is of interest to retailers who have emission reduction targets and urban planners concerned with sprawl. Are small local shops preferred over large, big-box retailers? A model of the retail...

摘要：This study examines the ability of government bond fund managers to time the bond market, based on their monthly or quarterly holdings of Treasury securities during the 1997-2006 period. We find that, on average, government bond funds exhibit significantly positive timing ability at the one-month horizon under an unconditional holdings-based timing measure. However, our results indicate that managers' actions based on public information can explain the documented positive timing ability-namely...

摘要：In this paper, we study the effects of three different kinds of search engine rankings on consumer behavior and search engine revenues: direct ranking effect, interaction effect between ranking and product ratings, and personalized ranking effect. We combine a hierarchical Bayesian model estimated on approximately one million online sessions from Travelocity, together with randomized experiments using a real-world hotel search engine application. Our archival data analysis and randomized exper...

摘要：An extensive literature on reputation signaling in prosocial settings has focused on an intrinsic desire for positive reputation. In this paper, we provide experimental evidence that some individuals are averse to both positive and negative reputation and will therefore respond to visibility by signaling that they are an '' average altruism type '' relative to their audience. We formalize our hypotheses about '' wallflower '' behavior in a theoretical model. Our experimental results show that ...

摘要：Game attendance resulting from ticket sales is the single largest revenue stream for Major League Baseball (MLB) teams. We propose a general multiple distributed lag framework following the Koyck family of models for estimating MLB attendance drivers and focus specifically on the differential direct and carryover effects of in-game promotions. By setting various model constraints, the proposed framework incorporates different forms of serial correlation and promotion-specific dynamic effects. ...

摘要：How do firms respond to entry in multi-sided markets? We address this question by studying the impact of Craigslist, a website providing classified-advertising services, on local U.S. newspapers. We exploit temporal and geographical variation in Craigslist's entry to show that newspapers with greater reliance on classified-ad revenue experience a larger drop in classified-ad rates after Craigslist's entry. The impact of Craigslist's entry on the classified-ad side appears to propagate to other...

摘要：We model a new product market opportunity as an option and ask whether it is best exploited by a large incumbent firm (integration) or by a small separate firm (nonintegration). Starting from a standard framework, in which value-maximizing investment and financing decisions are jointly determined, we show that integration protects assets in place value, whereas nonintegration protects option value and maximizes financial flexibility. We show that increases in standard measures of cash flow ris...

摘要：Whether and how trust and trustworthiness differ between a collectivist society, e. g., China, and an individualistic one, e. g., the United States, generates much ongoing scientific debate and bears significant practical values for managing cross-country transactions. We experimentally investigate how supply chain members' countries of origin-China versus the United States-affect trust, trustworthiness, and strategic information sharing behavior in a cross-country supply chain. We consider a ...

摘要：T his paper studies the effect of limited information in a sequential search setting where a single selection is to be made from a set of random potential options. We consider both a full-information problem, where the decision maker observes the exact value of each option as she searches, and a partial-information problem, in which the decision maker only learns the rank of the current option relative to the options that have already been observed. We develop a model that allows for a sharp c...
