摘要：Problem definition: Participant retention is one of the significant issues faced by clinical studies. This paper analyzes the economic impact of combining two mechanisms (monetary payments to participants and effort exerted during a clinical study) observed in practice to improve retention. Methodology/results: Given an incentive scheme, under full information and information asymmetry regarding participants' characteristics, we model the problem of identifying optimal payment and effort to im...

摘要：Problem definition: In this work, we examine how ridesharing platforms affect changes in short-term vehicle purchasing. On the one hand, if the introduction of such plat-forms motivates owners to use the idle capacity of their existing vehicles to accrue rents, vehicle sales might fall. On the other hand, if the platform induces would-be drivers to purchase new vehicles in order to participate, vehicle sales might rise. Academic/practical relevance: Whereas operations management researchers ha...

摘要：Problem definition: Initial product design decisions are critically important for mobile apps, which show a relatively short time from launch to peak usage, thus providing a narrow window for success and no time for course correction based on market reaction. Mobile apps are designed using a highly modular architecture based on software development kits (SDKs), with SDK choices being sequentially determined along three dimensions-multiplicity (total number of SDKs), compatibility (SDK co-occur...

摘要：Problem definition: We study the economic rationale for certified pre-owned (CPO) programs and characterize the mechanism through which they influence secondary markets to create value for durable goods firms and consumers. Academic/practical relevance: Our study on understanding the market impact of CPO programs is highly relevant for industry given their prevalence in practice. Our work also contributes to the adverse selection literature in the context of the lemons problem by uncovering th...

摘要：Problem definition: Online platforms that provide on-demand services are often threatened by the phenomenon of leakage, where customer-provider pairs may decide to transact off-platform to avoid paying commissions to the platform. This paper investigates properties of services that make them vulnerable or resistant to leakage. Academic/ practical relevance: In practice, much attention has been given to platform leakage, with platforms experimenting with multiple approaches to alleviate leakage...

摘要：Problem definition: Early research has documented significant growth in ride-hailing services worldwide and allied benefits. However, growing evidence of their negative externalities is leading to significant policy scrutiny. Despite demonstrated socioeconomic benefits and consumer surplus worth billions of dollars, cities are choosing to curb these services in a bid to mitigate first order urban mobility problems. Existing studies on the congestion effects of ride-hailing are limited, report ...

摘要：Problem definition: We consider a two-sided market competition problem where two platforms, such as Uber and Lyft, compete on both supply and demand sides and study the impact of precommitments in a variety of practically motivated instruments on the equilibrium outcomes. Academic/practical relevance: We extend a set of classic oligopoly pricing results to account for two-sided competition under demand uncertainty. Methodology: We investigate multi-stage competition games. Results: We start wi...

摘要：Problem definition: We study the optimal design of crowdfunding campaigns and develop a model that maximizes revenue for a given crowdfunding campaign by optimizing both the pledge level sought from donors and the duration of the campaign. Academic/practical relevance: Our model explains the patterns of backer/donor arrival and pledging observed on crowdfunding platforms, such as Kickstarter. This model can be used to calibrate the revenue impact from using prespecified pledge levels or campai...

摘要：Problem definition: We study the robust formulation of an inventory model with positive fixed ordering costs, where the unfulfilled demand is either backlogged or lost, the lead time is allowed to be positive, the demand is potentially intertemporally correlated, and the information about the demand distribution is limited. Methodology/results: We propose a robust cycle-based policy that manages inventory by dividing the planning horizon into nonoverlapping inventory cycles, where an order is ...

摘要：Problem definition: We consider a single-server queueing system where service quality is either high or low. The server, who knows its exact quality level, can signal this quality information to customers by revealing or concealing its queue length. Based on this queue disclosure action and the observed queue length in the case of a revealed queue, customers decide whether to join the system. Academic/practical relevance: The queue disclosure action is regarded as a signal indicating the servi...
