This paper compares three market structures in a dynamic dealer-mediated market with asymmetric information about an asset’s value. The compared market structures are (i) the continuous protocol of Glosten and Milgrom (1985), where a just-arrived trader trades immediately at a bid or an ask price publicly posted by the dealer, (ii) the periodic auction, wherein trades are cleared in batches, pu...

In this research, we build on our prior experience in constructing year-long call schedules for medical residents. A key challenge of this problem is its multi-criteria nature — the quality of a schedule is not measured in terms of cost, but rather depends on a number of (often competing) metrics. One way to solve multi-criteria optimization problems is by assigning weights to each metric so as...

In this paper, we present a framework for “opportunistic scheduling” that exploits the variation of the wireless channel conditions to improve spectrum efficiency. The objective of the scheduling schemes in this paper is to maximize the system performance in an opportunistic fashion, while satisfying various QoS requirements. We study three types of QoS requirements: the first is fairness in re...

We analyze three applied incentive compatibility conditions within a class of queueing problems motivated by the reassignment of flights to airport landing slots. A preexisting landing schedule becomes wasteful when airlines privately learn updates about their flights’ cancelations or feasible flight times. The FAA’s objective is to create a new queue that does not waste landing slots. We separ...
