摘要：Consumers often have needs that change in a dynamic fashion over time due to physiological, mental, or environmental variations. We develop a model to address a product strategy question on how to satisfy dynamic consumer preferences: Should a firm offer multiple standard products, each designed for a specific purpose (e.g., several specialized golf clubs), or a flexible product that can be reconfigured by consumers as their preferences change (e.g., one adjustable golf club)? Often the latter...

摘要：This study examines the strategic choices of two rival manufacturers between competition and coopetition. A complex relationship exists between these two firms, who manufacture substitutive products. In addition, each of these firms has an option to purchase (or sell) a key component from (or to) the other. We develop a benchmark competition model and two coopetition models in which the manufacturers compete for end-customer demand while simultaneously collaborating on component production thr...

摘要：This study examines the relationship between exogenous demand shock and market structure in India's influenza vaccine markets. Using a novel dataset of detailed purchasing information for vaccines in India, and exploiting the 2009-10 global H1N1 pandemic as an exogenous demand shock, we provide evidence of heterogeneous responses to the shock by domestic and multinational vaccine manufacturers in the influenza vaccine market relative to our control group of all other vaccine markets. We find t...

摘要：It is well-known that adding a little flexibility to the right place is an effective strategy to improve the performance of operations in the face of demand uncertainties, to ensure high level of capacity utilization. However, given that system disruptions are ubiquitous, the legacy flexibility designs may perform poorly under disruptions to supply or capacity installations. In this study, we focus on the design of reliable and sparse flexibility structures that consistently meet a reasonable ...

摘要：We consider pricing problems when customers choose under the Markov chain choice model. In this choice model, a customer arriving into the system is interested in a certain product with a certain probability. Depending on the price charged for this product, the customer decides whether to purchase the product. If the customer purchases the product, then she leaves the system. Otherwise, the customer transitions to another product or to the no purchase option with certain transition probabiliti...

摘要：We examine the operations, fairness, and social implications of fair trade certified products. We consider the market for fair trade certified products, which may serve as a substitute to a regular product. A fair trade organization chooses standards for the certification, namely, the (unit) premium and minimum fraction of fair trade raw materials, to maximize the total premium transferred to farmers. We analyze the operations of various stakeholders in the fair trade value chain, as well as t...

摘要：This study investigates a novel mechanism-multiple-winner award rules-that are widely used in e-procurement auctions and crowdsourcing sites. In many e-procurement auctions, the auctioneer (i.e., the buyer) specifies three rules before the auction starts: (i) the size of the finalist set (from which the winner[s] will be chosen); (ii) the number of winners; and (iii) the allocation of the contract among the winners. We examine how these three rules affect auction performance using a dataset of...

摘要：Although vendor-managed inventory (VMI) programs have gained popularity in practice, some empirical studies report that their implementations have not been successful. We conduct experiments to investigate behaviors in a supply chain where a supplier replenishes inventories for a retailer according to a VMI program under a revenue-sharing contract. The results show that subjects' decisions deviate significantly from the standard theoretical predictions because the retailer presents equality pr...

摘要：Supplier development and supplier integration are two deeply interconnected strategic tools that manufacturers often employ to improve the efficiency and competitiveness of their supply chains. This paper studies the interaction of these two strategic decisions in a competitive environment. Specifically, we consider a duopoly model where two supply chains, each consisting of one manufacturer and one supplier, sell substitutable products in the market. Each manufacturer orders components from i...

摘要：We consider call centers that have multiple (potentially inter-dependent) demand arrival streams. Workforce management of such labor intensive service systems starts with forecasting future arrival demand. We investigate the question of whether and when to jointly forecast future arrivals of the multiple streams. We first develop a general statistical model to simultaneously forecast multi-stream arrival rates. The model takes into account three types of inter-stream dependence. We then show w...
