摘要:In 1964, Kenneth Lane proposed an algorithm to optimize the production schedule of a single-metal, single-processor open pit mine. For this, he proposed a policy based on varying, over time, the so-called cutoff grade-or grade threshold used to determine if extracted material should be ore (processed material) or waste (thrown away). Lane's algorithm had a profound impact on the mining industry. However, though it has been used in multiple commercial software systems and has traditionally been...

摘要:We study the problem of learning personalized decision policies from observational data while accounting for possible unobserved confounding. Previous approaches, which assume unconfoundedness, that is, that no unobserved confounders affect both the treatment assignment as well as outcome, can lead to policies that introduce harm rather than benefit when some unobserved confounding is present as is generally the case with observational data. Instead, because policy value and regret may not be ...

摘要:We exploit cross-sectional variation in the predictable changes in asset volatility following corporate acquisitions to identify the effect of business risk on capital structure. We find that postmerger changes in leverage and cash holdings are strongly predicted by expected asset volatility changes estimated using premerger information. These capital structure adjustments are partly achieved through the choice of payment method. Our findings provide direct evidence for the coinsurance effect ...

摘要:This study examines cross-regional differences in news tone for the same news event and relates it to local stock ownership of individual investors using a combination of detailed investor and media data. The results show that news tone amplifies the overall attention effect and decreases the difference between the trading activities of local and nonlocal investors when locally sourced news is republished across regions. In general, trading activity decreases for given republished news, but it...

摘要:We investigate how different types of social information affect the demand characteristics of firms competing through service quality. We first generate behavioral hypotheses around both consumers' learning behavior and firms' corresponding demand characteristics: market share, demand uncertainty, and rate of convergence. We then conduct a controlled human-subject experiment in which a consumer chooses to visit one of two firms, each with unknown service quality, in a repeated interaction and ...

摘要:This paper illustrates how supply chain (SC) analytics could provide strategic and operational insights to evaluate the risk-based allocation of regulatory resources in food SCs, for management of food safety and adulteration risks. This paper leverages data on 89,970 tests of aquatic products extracted from a self-constructed data set of 2.6 million food safety tests conducted by the China Food and Drug Administration (CFDA) organizations. The integrated and structured data set is used to con...

摘要:In enterprise software markets, firms are increasingly using services-based business models built on open-source software (OSS) to compete with established, proprietary software firms. Because third-party firms can also strategically contribute to OSS and compete in the services market, the nature of competition between OSS constituents and proprietary software firms can be complex. Moreover, their incentives are likely influenced by the licensing schemes that govern OSS. We study a three-play...

摘要:Although prior research in traditional equity financing shows that male founders are preferred, emerging evidence in low-stakes crowdfunding (e.g., rewards-based crowdfunding) indicates that female entrepreneurs may have an advantage, particularly with female investors. We seek to examine whether investors in high-stakes equity crowdfunding, which includes elements from both traditional equity financing and low-stakes crowdfunding, respond differently to male and female founders. Specifically,...
