摘要：Firms dread product recalls. Consequently, firm leaders may take steps to avoid recalls when possible, or to avoid the blame for them when there is someone else to blame. We analyze how the appointment of a new chief executive officer (CEO) for a firm in the consumer product industry influences the hazard of subsequent recalls initiated by that firm. Using 25 years of consumer product industry data, including 125 publicly traded firms that experienced 307 new CEOs and 584 voluntary recalls fro...

摘要：In this study, we examine how firms can leverage reference-group effects (RGEs) in sequential introduction of upgraded products. RGEs arise when consumers engage in social comparisons: leaders desire to distinguish themselves from followers and followers desire to mimic leaders. We find that RGEs have a non-monotonic impact on the profitability of product upgrades: a stronger RGE first increases and then decreases profits. This inverted-U effect is fundamentally driven by two opposite effects ...

摘要：Consumer Surplus is traditionally defined for the case where demand is a deterministic function of the price. However, demand is usually stochastic and hence stock-outs can occur. Policy makers who consider the impact of different regulations on Consumer Surplus often ignore the impact of demand uncertainty. We present a definition of the Consumer Surplus under stochastic demand. We then use this definition to study the impact of demand and supply uncertainty on consumers in several cases (add...

摘要：Creative crowdsourcing is an innovative online business model in which a platform marshals independent professionals (e.g., designers) to conduct creative work projects. Typically, clients submit project requests stochastically to a platform which possesses a pool of registered designers. For each submitted project, designers decide whether to participate and attempt to submit a design, and the client either chooses a winner among all submissions, or rejects them all, based on subjective crite...

摘要：Managing patients with chronic conditions is challenging. It requires timely care adjustments based on the patient's health status. We leverage big data to optimize patient monitoring frequencies and improve treatment. Our research is motivated by the need to improve patient care at the Veterans Affairs (VA) hospitals. We propose an integrated model to better serve patients with chronic kidney disease (CKD). CKD is prevalent, complex, and costly. The demand for kidney care has steadily increas...

摘要：This study investigates diagnostic testing and pharmacy expenditures, commonly referred to as ancillary costs in the United States acute-care hospitals. These ancillary costs are charges associated with services provided to support patient treatment, including laboratory, radiology, and pharmacy charges. Despite of investment in inter-organizational and technological collaboration practices, these costs continue to rise. Our research examines the role of individual healthcare providers, namely...
