摘要：In the presence of successive product generations, most consumers are repeat buyers who may decide to purchase a future product generation even before its release. Therefore, after a new product generation enters the market, its sales often exhibit a declining pattern, which renders traditional diffusion models unsuitable for characterizing consumers' decisions on upgrade timing. In this study, we propose an Exponential-Decay proportional hazard model (Expo-Decay model) to predict consumers' t...

摘要：Innovation contests within firms offer the potential to tap latent employee expertise across the organization and expand innovation beyond the core R&D teams. Still, firms undertaking an internal contest, unlike the more commonly studied external contests, incur significant opportunity costs when employees divert their efforts toward the contest (and away from their routine work). Managing this key challenge forms the focus of the current study, with the overarching question being How should f...

摘要：E-commerce supply chains and their members face risks from cyber-attacks. Consumers who purchase goods online also risk having their private information stolen. Thus, businesses are investing to improve cyber-security at a nontrivial cost. In this paper, we conduct a Stackelberg game-theoretical analysis. In the basic model, we first derive the equilibrium pricing and cyber-security level decisions in the e-commerce supply chain. Based on real-world practices, we then explore whether governmen...

摘要：George Dantzig introduced the world to the power of optimization, creating trillions of dollars of value and saving countless years of life across the globe. Linear programs and Dantzig's many other contributions to optimization have driven enormous increases in productivity throughout the global economy. Linear programming has also become a vital tool in advancing artificial intelligence and machine learning.

摘要：Warfare afflicts millions and creates unparalleled operational challenges in the developing world. With data from war-torn Colombia, I examine the effects of civil war on firms' total factor productivity (TFP) using propensity score and conflict hotspot models. I find that warfare increases TFP in service firms, such as public administration and defense, by up to 12.68%, whereas it decreases TFP in manufacturing and other nonservice companies by up to 3.64% a year after a violent episode occur...

摘要：The COVID-19 pandemic has had profound effects on grocery retailers, forcing them to make many operational changes in response to public health concerns and the shift in customers' shopping behavior. Grocery retailers need to understand the impact of pandemic conditions on their operations, but the literature has not modeled and analyzed this issue. We bridge this gap through economic models that consider the documented changes in the customers' shopping behavior during the COVID-19 pandemic, ...

摘要：Since the outbreak of the COVID-19 pandemic, the effectiveness of stay-at-home orders implemented in many states in the United States has been the subject of ongoing debate. Whereas proponents believe these orders help reduce person-to-person contact and therefore the spread of the pandemic, opponents argue these orders are unnecessary and ineffective. In this study, we use eight states that did not implement the orders as a control group and six neighboring states that did implement them as a...

摘要：Over 60% of decedents in the United States have not given first-person consent for tissue donation; thus, receiving consent from next-of-kin (NOK) is a potentially powerful way to improve access to donor tissues. As a more informed NOK is more likely to consent to tissue donation, we introduced the delivery of two alternative videos that discuss the benefits of donation as part of the donation request. One was an animated, freely available video developed by the US Health Resources and Service...

摘要：Two-sided platforms have become omnipresent. In this context, firms compete not only for customers but also for flexible self-scheduling workers who can work for multiple platforms. We consider a setting where two-sided platforms simultaneously choose prices and wages to compete on both sides of the market. We assume that customers and workers each follow an endogenous generalized attraction model that accounts for network effects. In our model, the behavior of an agent depends not only on the...
