摘要：We examine inventory decisions in a multiperiod newsvendor model. In particular, we analyze the impact of budget cycles in a behavioral setting. We derive optimal rational decisions and characterize the behavioral decision-making process using a short-sightedness factor. We test the aforementioned effect in a laboratory environment. We find that subjects reduce order-up-to levels significantly at the end of the current budget cycle, which results in a cyclic pattern during the budget cycle. Th...

摘要：Product proliferation and changes in demand require that retailers regularly determine how items should be allocated to retail shelves. The existing shelf-space literature mainly deals with regular retail shelves onto which customers only have a frontal perspective. This study provides a modeling and solution approach for two-dimensional shelves, e.g., for meat, bread, fish, cheese, or clothes. These are categories that are kept on tilted shelves. Customers have a total perspective on these sh...

摘要：This study is motivated by the ubiquitous practical existence of common retailer distribution channels (e.g., a grocery store offering multiple brands of the same product). Demand interdependence (product substitutability) among various brands is critical and thus we investigate its impact on firms' profits. Using an economic framework with manufacturers operating as Stackelberg leaders, our analysis reveals unique and substantive insights dependent on the underlying market demand structure, a...

摘要：This study investigates the efficacy of zero-interest early payment financing (alternatively referred to as early payment) and positive-interest in-house factoring financing in a pull supply chain with a capital-constrained manufacturer selling a product through a capital-abundant retailer. Early payment is the prepayment of a wholesale cost to the manufacturer, whereas in-house factoring is a loan service provided to the manufacturer by a branch financing firm of the same retailer. We find th...

摘要：Social media-based online communities are becoming increasingly popular for various social interactions, including those for healthcare and health-related activities. The benefits from these activities, however, are constrained by how a platform is designed, as a platform's design defines what activities can be done and how individuals can engage and interact on the platform. In this study, we focus on weight-loss communities and social tools that facilitate social communication and establish ...

摘要：Using laboratory experiments, we study how communication media affect cooperation in a supply chain when the buyer has private information about the end-customer demand. We show that coordinating contracts (quantity discount) combined with efficient means to electronically share private information (one-way, pre-defined text message) result in almost efficient outcomes, but only if verbal communication takes place before the actual contracting stage. Content analysis shows that verbal communic...

摘要：Use a unique dataset collected from a large classified ads website, we empirically examine the effect of the offline call intensity on the online consumer purchase probability of digital services and the carryover effect of the call intensity. We find that the online consumer purchase probability is increasing in the call intensity but at a decreasing rate. We further demonstrate that the decreasing rate is sizable enough that the relationship between the online consumer purchase probability a...

摘要：In vertically integrated energy systems, integration frequently entails operational gains that must be traded off against the requisite cost of capacity investments. In the context of the model analyzed in this study, the operational gains are subject to inherent volatility in both the price and the output of the intermediate product transferred within the vertically integrated structure. Our model framework provides necessary and sufficient conditions for the value (NPV) of an integrated syst...

摘要：Stem-cell transplantation is the last chance for patients of various blood-related diseases. Stem-cell donation centers admit patients in need of a stem-cell transplant and search for a perfect match between the patients and donors. The search process is time-consuming and requires expensive advanced equipments, in particular for DNA typing. In this study, we are concerned with a capacity planning problem in a network of stem-cell donation centers. The underlying optimization model integrates ...

摘要：Our study contributes to the scholarly debate whether organizational units should have a narrow focus and admit a homogeneous patient cluster or whether they should admit a pool of patient clusters. We investigate whether the benefits of increased volume through pooling patients outweigh the disadvantages of increased heterogeneity and pursue our analysis in the context of neonatal care. Our empirical studies relies on 4020 patient episodes collected in 18 German neonatal intensive care units ...
