摘要：We use a unique empirical setting to investigate the spillover of quality knowledge across supply chains and to the examine contingencies that affect such spillover. We analyze the quality performance of 191 suppliers, who utilize the same facilities to manufacture similar products for two distinct businesses: one that makes cars and the other that makes commercial vehicles. From 2006 to 2009, the car business undertook 2,121 quality improvement initiatives at these suppliers, while the commer...

摘要：We model how a judge schedules cases as a multiarmed bandit problem. The model indicates that a first-in-first-out (FIFO) scheduling policy is optimal when the case completion hazard rate function is monotonic. But there are two ways to implement FIFO in this context: at the hearing level or at the case level. Our model indicates that the former policy, prioritizing the oldest hearing, is optimal when the case completion hazard rate function decreases, and the latter policy, prioritizing the o...

摘要：For many early-stage entrepreneurs, hiring the first employee is a critical step in the firm's growth. Doing so often requires significant time and monetary investments. To understand the trade-offs involved in deciding when to hire the first employee and how hiring differs in entrepreneurial settings from more established firm settings, we present a simple growth model that depends on two critical inputs for revenue generation: the entrepreneur's time and money. We show that without hiring, t...

摘要：We study a periodically reviewed multiechelon serial inventory system with a capacity constraint on the order quantity at each stage. The cost criterion we use to evaluate inventory policies for this system is the sum of the expected long-run average holding and shortage costs. It is well known that for this problem, characterizing the structure of the optimal policy and computing it are very difficult. We consider the use of echelon base-stock policies for our system (even though they are kno...

摘要：When does increased service quality competition lead to customer defection? And, which customers are most likely to defect? Our empirical analysis of 82,235 customers exploits the varying competitive dynamics in 644 geographically isolated markets in which a nationwide retail bank conducted business over a five-year period. We find that customers defect at a higher rate from the incumbent following increased service quality (price) competition only when the incumbent offers high (low) quality ...

摘要：This paper discusses the origins of the supply chain contracting literature as well as its current state. It argues that its origins go back further than many scholars realize. It also makes the case that the field expanded rapidly, creating a bubble that has largely burst. However, there have been lasting implications that affect both how we teach supply chain management and the kind of research that is done under the heading of operations management.

摘要：For many entrepreneurs, time is a key constraint. They need to invest time to achieve growth, but also lose time because of recurring crises. We develop a simple stochastic dynamic program to model how an entrepreneur should prioritize between improving processes to reduce crises versus harvesting revenue or ensuring future growth. We show that it is initially optimal to prioritize process improvement: an entrepreneur should strive for high process quality early in the venture's growth process...

摘要：Online shoppers value lenient return policies as they are unable to assess whether products match their expectations. We study how consumers' discount-seeking purchase deferrals affect online retailers' return policy choices. Lenient returns may induce higher full-price sales by limiting consumer regret, while signaling clearance unavailability risk. Contrasting earlier research that concluded a monopolist must set the refund at the clearance price when strategic consumers were overlooked, we ...

摘要：We investigate information flow in two-tier supply chains, where retailers order from suppliers and sell in a market with uncertain demand. The retailers each have access to a demand signal and can exchange signals (horizontal information sharing). The suppliers can offer the retailers differential payments to gain access to their signals (vertical information acquisition). We demonstrate that retailer competition is a necessary condition to sustain information flow, whereas supplier competiti...
