摘要：We investigate newsvendor ordering behavior under competition. We present a laboratory experiment that documents the behavioral ordering regularities in competitive newsvendor environments, and an analytical model extending the standard theory of newsvendor competition by including an optimal best-response policy for competing with a behaviorally biased newsvendor. We test the effectiveness of this policy using an out-of-sample experiment and find that it results in improved market share, serv...

摘要：Eroglu et al. (2013) study a retailer with limited shelf capacity and a backroom. They study a continuous review (r, q) ordering policy with a known order quantity, q. Assuming that backorders can be satisfied from the backroom inventory (if available), they find the expression for the optimal reorder level, r. Our work builds on Eroglu et al. (2013). We correct an erroneous derivation of the expected overflow term, as well as derive an exact expression for the expected cost function, and henc...

摘要：We examine the effect of a hospital's objective (i.e., non-profit vs. for-profit) in hospital markets for elective care. Using game-theoretic analysis and queueing models to capture the operational performance of hospitals, we compare the equilibrium behavior of three market settings in terms of such criteria as waiting times and patient costs from waiting and hospital payments. In the first setting, a monopoly, patients are served exclusively by a single non-profit hospital; in the second, a ...

摘要：All major world economies are exhibiting a shift from products to services in terms of relative share of GNP and employment. A well accepted explanation for this shift to services has been the lower productivity growth in services relative to manufacturing. A second trend visible in the United States and other advanced economies is that from material-intensive to information-intensive sectors with the latter growing relative to the former. There does not seem to be a generally accepted explana...

摘要：We study a minimum total commitment (MTC) contract embedded in a finite-horizon periodic-review inventory system. Under this contract, the buyer commits to purchase a minimum quantity of a single product from the supplier over the entire planning horizon. We consider nonstationary demand and per-unit cost, discount factor, and non-zero setup cost. Because the formulations used in existing literature are unable to handle our setting, we develop a new formulation based on a state transformation ...

摘要：Several contradictions are noted among the Economic Order Quantity (EOQ), Just-In-Time (JIT), and Optimized Production Technology (OPT) approaches and the economic framework for profit maximization. A fundamental model referred to as the Economic Manufacturing Quantity (EMO) is developed and examined for its integrating implications for the three approaches. An implication for the classic EOQ approach is that the balance between setup and inventory carrying costs is valid when a production fac...

摘要：Since the development of the Internet, thousands of manufacturers have been referring consumers visiting their websites to some or all of their retailers. Through a model with one manufacturer and two heterogeneous retailers, we investigate whether it is an equilibrium for the manufacturer to refer consumers exclusively to a retailer or nonexclusively to both retailers. Our analysis indicates that nonexclusive referral is the manufacturer's equilibrium choice if the referral segment market siz...

摘要：In this study, we consider a supplier's contract offerings to a buyer who may obtain improved forecasts for her demand over time. We investigate how the supplier can take advantage of the buyer's better forecasts and what kind of contracts he should offer to the buyer in order to maximize his profits. We model a natural forecast evolution where the buyer can obtain a more accurate forecast closer to the selling season. We assume there is information asymmetry between the buyer and the supplier...

摘要：This study is based on the analysis of field data on the revenues and patient flows that we collected on all adult emergency department (ED) visits to a level-1 trauma, tertiary referral center. Our objective was to provide researchers in operations a rich overview of the processes, resources, and metrics of financial and operations performance in the ED. We analyze how patients, physicians, hospitals/physician employer groups, and payers are party to the value created and financial workflow o...

摘要：Many service firms deliver services via a mix of internally developed and delivered (i.e., insourced) and externally developed and delivered (i.e., outsourced) service processes. Service process outsourcing is especially common in e-retailing. Portions of e-retail customer ordering processes and delivery processes can be digitized and contracted to thirdparty vendors. Via outsourcing, service systems change from dyadic to triadic. Prior research examines consumer perceptions of dyadic (consume...
