讲座摘要：
We study advance selling and upgrading in a priority queue setting that emerges in the amusement park industry. Customers choose to buy the fast-track or regular tickets depending on their heterogeneous waiting costs. At the park entrance, customers can choose tickets based on the observed congestion levels. Advance tickets are cheaper, but customers suffer from congestion uncertainty. Upgrading options allow customers to purchase regular tickets in advance and upgrade on-site if the congestion turns out to be high. Our objective is to find the optimal pricing scheme to maximize revenue. We find that if all customers arrive in advance, in many cases advance-and-spot selling without upgrading achieves the upper bound—the optimal extra revenue from the state-dependent priority pricing, hence the upgrading option is not necessary. On the other hand, if some customers arrive on the spot, allowing upgrading is more likely to generate more revenue. In scenarios where upgrading increases the revenue, the upgrading options, despite offering consumers greater flexibility, hurt consumer surplus. When both online and offline customers exist, it could be more profitable to focus advance and upgrading prices on online customers and focus spot prices on offline customers.
