　　（1）主题：Service Pricing with Loss Averse Customers

　　（2）时间：2016年6月7日（周二）上午10:15

　　（3）内容简介：

　　We consider a queueing system in which customers are loss averse towards both price and delay attributes: customers compare these two attributes to their rational expectations of the outcomes, with losses being more painful than equal-sized gains being pleasant. We first study customers' equilibrium queueing strategies. We find that, in contrast to the traditional case in which loss aversion is not considered, there could exist three equilibrium strategies, among which one is is preferred in the sense that customers’ utility is highest atthis equilibrium. We then study the optimal pricing problem for a monopoly server. We show that loss aversion polarizes queues, making long queues even longer and short queues even shorter. Furthermore, loss aversion towards the delay attribute drives down the optimal price whereas loss aversion towards the price attribute pushes up the optimal price. We also find that profit- and welfare-maximizing prices are not the same in a monopoly market. Finally, we consider pricing competition in a duopoly market and find that the conclusions depend on the capacity relative to the market size. Interestingly, with loss-averse customers, a firm can obtain a higher profit in a duopoly market than that in a monopoly market.

　　（1）主题：Fee-for-Service vs Bundled Payment: An Analysis from Aspects of Congestion and Service Quality

　　（2）时间：2016年6月8日（周三）上午10:15

　　（3）内容简介：

　　To contain healthcare cost and improve quality, there is an on-going debate regarding the impact of different reimbursement schemes on patient welfare.  In this paper, we examinetwo commonly used reimbursement schemes: (1) a Fee-For-Service (FFS) reimbursement scheme under which health care providers (HCPs) are paid for each service they provide; and (2) a Bundled Payment (BP) reimbursement scheme under which the HCP receives a lump sum payment for an entire episode of care (regardless of how many times a patient is readmitted to the system).  To examine the interplays among the patients' ``endogenous'' decision about whether or not to seek treatment from a designated HCP, the HCP's service rate decision, and the funder's reimbursement payment decision under the FFS and BP schemes, we present a model by using an M/M/1 queue with Bernoulli feedback to capture the patients' readmission process.  We determine the equilibrium outcomes (the patients' endogenous arrival rate, the HCP's service rate, and the funder's reimbursement under both the FFS and BP schemes). We find that, in general, the BP scheme improves the patient welfare and service quality (i.e., a lower readmission rate) but the FFS scheme results in a shorter waiting time.  However, when the funder's budget is large and the patient population is medium, both schemes are equally efficient in terms of all performance metrics including the patient welfare, service quality, the waiting time per visit and the total waiting time.
