摘要：We consider a class of three-objective mixed-integer linear programs (MILPs) where at least one of the objective functions takes only discrete values. These problems commonly occur in MILPs where one or more of the three objective functions contain only integer decision variables. In such problems, the nondominated set consists of the union of nondominated edges and individual nondominated points. The nondominated edges can provide valuable insights on the trade-offs between the two continuous...

摘要：Partial vertical ownership describes a situation in which a firm holds financial shares in either its supplier (referred to as partial backward integration) or its customer (partial forward integration). We study the effect of such financial interconnectedness on two operational decisions: capacity investment and information exchange. In our model, a retailer, who has superior information about the future market demand, has passive financial holdings in the supplier. Although this passive fina...

摘要：The prior literature on analyst forecasts has focused almost exclusively on firms that just meet or beat the mean or median consensus analyst forecast, without much regard to alternative benchmarks within the forecast distribution. Anecdotal evidence suggests that there is institutional significance to the lowest (minimum) and highest (maximum) analyst earnings forecast. We rigorously explore whether these two new benchmarks actually have incremental significance and, if so, whether there are ...

摘要：We study the relationship between new intermediaries and regulatory arbitrage, analyzing marketplace credit around a tightening of mortgage loan-to-value (LTV) caps in several cities in China in 2013. Using novel data covering over 20% of Chinese marketplace credit as well as the universe of loans and loan applications at a leading online lending platform, we provide evidence consistent with home buyers borrowing online to bypass the tighter LTV cap. Our findings point to new, lightly regulate...

摘要：The log realized volatility (RV) is often modeled as an autoregressive fractionally integrated moving average model ARFIMA(1, d, 0). Two conflicting empirical results have been found in the literature. One stream shows that log RV has a long memory (i.e., the fractional parameter d > 0). The other stream suggests that the autoregressive coefficient alpha is near unity with antipersistent errors (i.e., d < 0). This paper explains how these conflicting empirical findings can coexist in the conte...

摘要：Improving traceability in food supply chains has been a big part of ongoing effort to reduce contamination risks and food waste. Recent technology advancement such as blockchain technology has propelled innovative retailers to promote food traceability system adoption in their supply chains. We develop a three-tier supply chain model with multiple upstream (tier 2) suppliers to investigate how traceability technology adoption affects incentives of supply chain members and whether and how its a...

摘要：Operating under both supply-side and demand-side uncertainties, a mobile-promotion platform conducts advertising campaigns for individual advertisers. Campaigns arrive dynamically over time, which is divided into seasons; each campaign requires the platform to deliver a target number of mobile impressions from a desired set of locations over a desired time interval. The platform fulfills these campaigns by procuring impressions from publishers, who supply advertising space on apps via real-tim...

摘要：We introduce a novel approach to measure the founding strategic differentiation of startups and its relationship to follow-on performance. We use natural language processing and historical websites to estimate the similarity between the founding website of an individual startup, the historical website of public firms at the startup's founding year, and the founding website of other startups founded in the same year. We propose that distance in the value proposition stated in these websites rep...

摘要：We investigate the causal effect of performance pay and conversations about performance in 224 stores of a retail chain implementing a field experiment with a 2x2 factorial design. In the performance pay treatments, managers receive a bonus, which is a simple linear function of the profits achieved above a threshold value. In the performance review treatments, managers have to report their activities undertaken to increase profits in regular meetings. We find that whereas performance pay did n...

摘要：We study a bilateral trade problem with multiunit demand and supply and one-dimensional private information. Each agent geometrically discounts additional units by a constant factor. We show that when goods are complements, the incentive problem measured as the ratio of second-best to first-best social surplus-becomes less severe as the degree of complementarity increases. In contrast, if goods are substitutes and each agent's distribution exhibits linear virtual types, then this ratio is a co...
