活动简介：

We examine the optimal pricing decisions of a firm that offers both dedicated service options and a probabilistic service, allowing customers to select multiple services in advance and ultimately receive one. Customers are heterogeneous in their preferences. We consider two pricing schemes for the probabilistic service: allocation-dependent pricing, where customers pay based on the service they receive, and fixed pricing, where a preset price is charged regardless of the outcome. Modeling the system as a loss system, we characterize customer equilibrium behavior and the firm’s optimal pricing under both schemes.

Our results show that introducing a probabilistic service always enhances firm profit and improves service efficiency and quality by enabling finer customer segmentation and leveraging pooling effects across facilities. Under allocation-dependent pricing, all customers obtain positive utility, capacity expansion may not increase and can even reduce profit, and offering only probabilistic service can be advantageous. Compared with fixed pricing, allocation-dependent pricing yields lower firm profit but higher customer surplus. Moreover, probabilistic service leads to a win–win outcome under allocation-dependent pricing, whereas it results in a win–lose outcome under fixed pricing.
