摘要：Noncommunicable diseases (NCDs) are among the largest health emergencies nowadays. Although a large proportion of NCDs can be prevented effectively via good life habits, these remain ubiquitous and one main reason is people's self-control problem caused by time-inconsistent, present-biased preferences. In this situation, we wonder whether a long-term conditional cash transfer (CCT) program, which is known to be effective in shaping people's behaviors but expensive, can be a viable solution. We...

摘要：The development of a new drug is costly and uncertain. As such, pharmaceutical firms often collaborate to develop new drugs. We examine the conditions under which firms should collaborate rather than compete in new drug development. We model the collaboration vs. competition decision problem for two firms using a game-theoretic model and derive the collaboration conditions. Our study demonstrates that development cost and uncertainties in drug treatment efficacy and safety and patient enrollme...

摘要：Service contracts are common practice in some industries while being eliminated in others. To investigate this phenomenon, we identify expectation-reality discrepancy (ERD) as a key determinant. A provider's ERD is defined as consumers' ex-ante expected valuation minus their ex-post realized valuation of the provider's service. Our analysis reveals that providers' contract strategies critically depend on their ERDs rather than the true service valuations. A provider with a higher ERD is more l...

摘要：While batch processes are ubiquitous across industries, there is little understanding of the determination of the capacity (i.e., the maximum long-term output rate) of such processes. In this study, we consider processes with collaboration (activities may require multiple resources simultaneously) and multitasking (the same resource may be needed for multiple activities), and characterize the capacity of an arbitrary deterministic, single-product process with batch processing and (activity) se...

摘要：Experimental results support that overconfident newsvendors deviate from the optimal inventory levels to place orders closer to the mean of demand distributions, thereby lowering profits. To improve performance, we investigate whether nonstandard preferences based on prospect theory can manage overconfident newsvendors. We develop a framework where a manager determines a profit-based target, which serves as a reference point in the newsvendor's utility function. We show that target-setting can...

摘要：As global brands assume more accountability for their extended supply chains, some request that their first-tier suppliers in turn adopt sustainable procurement practices, thereby cascading sustainability requirements to second-tier suppliers. However, such cascading has not yet become institutionalized. We partnered with a leading sustainability electronics company-here called Tronics-to investigate which Chinese suppliers are more likely to adopt sustainable procurement and when Tronics' pow...

摘要：This study considers a public service system consisting of two service providers with different service capacities and qualities, such as healthcare or transportation systems. Such a system is called a two-tier service system (TTS). The service provider with higher service capacity and quality charges a higher price and is called a charge service provider, denoted by CSP, while the other service provider charges a lower price and is called a free service provider, denoted by FSP. We study the ...

摘要：In this study, we consider the problem of estimating demand functions using historical sales data. In particular, we study how using aggregate data may result in bias in such estimations. We consider a log-log demand model, and two ways of how the price in the aggregate data is calculated, simple average price or weighted average price. We study whether there exists estimation bias in each of the two cases as well as the direction of the bias. We show that in general, the correlation between a...

摘要：We investigate the trade-off between acquisition and retention efforts when customers are sensitive to the quality of service they receive, that is, whether they get timely access to a company's resources when requested. We model the problem as a multi-class queueing network with new and returning customers, time-dependent arrivals, and abandonment. We derive its fluid approximation; a system of ordinary linear differential equations with continuous, piecewise smooth, right-hand sides. Based o...

摘要：This study studies the impact of loss aversion on queue configurations in a doubled-ended queueing system such as taxi stations. We assume that there exist two types of demands/passengers, namely, the short-haul and long-haul, with long-haul demand offering a larger monetary reward for drivers. Loss-averse drivers decide to either join or balk based on their overall utility. We first consider the passenger-side system to be a loss system; that is, an arriving passenger balks if there is no tax...
