摘要：In this study, we provide an alternative approach for proving the preservation of concavity together with submodularity, and apply it to finite-horizon non-stationary joint inventory-pricing models with general demands. The approach characterizes the optimal price as a function of the inventory level. Further, it employs the Cauchy-Schwarz and arithmetic-geometric mean inequalities to establish a relation between the one-period profit and the profit-to-go function in a dynamic programming sett...

摘要：Framework agreements (FAs) are commonly used by relief organizations to cooperate with suppliers to pre-position relief items. Many Chinese local authorities with disaster responding experience choose a specific type of FA, the fixed framework agreement (FFA), which contains fixed terms for item quality, quantity, price, and delivery lead time. These FFAs, however, do not fully motivate suppliers to further improve the effectiveness of a humanitarian logistics (HL) operation. We suggest using ...

摘要：We study peer effects on individuals' contributions to a major form of word of mouth-online reviews. Provided by either consumers or third-party professionals, online reviews influence consumer purchasing decisions and hence sales. Individuals have conflicting incentives of free riding and contributing to social capital when writing reviews. We leverage a natural experiment, which led to an exogenous expansion in the user population of a major online review platform, to better understand the t...

摘要：Hospital emergency departments (EDs) provide around-the-clock medical care, and as such are generally modeled as nonterminating queues. However, from the care provider's point of view, ED care is not a never-ending process, but rather occurs in discrete work shifts and may require passing unfinished work to the next care provider at the end of the shift. We use data from a large, academic medical center ED to show that the patients' rate of service completion varies over the course of the phys...

摘要：Simple selling mechanisms are very appealing in practice, yet they may limit the firm's ability to extract a large consumer surplus. In this paper, we study the efficiency of a simple pure bundling mechanism in extracting the consumer surplus in the presence of nonnegative marginal costs and correlated valuations. The main question we address is how to quantify the benefits of adopting a simple pure bundling mechanism relative to other more complicated mechanisms, such as mixed bundling. We de...

摘要：We analyze a firm's investment in environmental process improvement (EPI) to reduce the environmental impact (EI) of its manufacturing processes in relation to various internal firm characteristics and in response to different external regulatory drivers. We provide a deep understanding of how these internal and external forces cause the firm to pursue EPI earlier or later in the planning horizon and at an increasing or a decreasing rate over time. In particular, we show how a regulator can dr...

摘要：Using an online experiment, this study examines the efficacy of two idea evaluation processes: scoring vs. ranking in the context of innovation management. In the scoring process, the evaluators are asked to rate the quality of each idea by assigning it a score (e.g., from 0 to 10), while in the ranking process the evaluator simply orders all ideas according to their perceived qualities. Our results suggest that the scoring process strictly outperforms the ranking process in terms of the likel...

摘要：Reward advertising is an emerging monetization mechanism for app developers in which consumers choose to view ads in exchange for apps' premium content. We provide the first economic analysis of reward advertising by studying the implications of offering reward ads, either by itself, or in conjunction with direct selling of premium content. We find that the condition for offering reward ads is surprisingly simple, and it is often optimal to offer reward ads jointly with direct selling of premi...

摘要：Buyers often procure distinct goods and services from the same supplier. Accordingly, business exchanged in one setting may affect exchanges between the buyer and supplier in other settings. We study how business procured via online business-to-business (B2B) auctions is affected by business exchanged between the buyer and supplier concurrent to the auctions (concurrent business). Using two transactional datasets, one with auctions held by a large buyer of transportation services over a 4-year...

摘要：Disaster relief organizations increasingly engage in social conversations to inform social media users about activities such as evacuation routes and aid distribution. Concurrently, users share information such as the demand for aid, willingness to donate and availability to volunteer through social conversations with relief organizations. We investigate the effect of this information exchange on social engagement during disaster preparedness, response, and recovery. We propose that the effect...
