Discrete Pricing and Institutional Design of Dealership Markets

Abstract

This paper models trade in dealership markets when the price grid is in discrete units. Strategic interaction among market makers is complex: Because prices are no longer determined by a zero expected profits condition, priority rules and the timing of offers—do market makers submit price schedules first, or do traders first submit their orders and then market makers set prices—have significant effects on equilibrium outcomes. Discreteness effectively limits competition and permits market makers to offer profitable quotes. In order-driven institutions where traders first submit orders, absolute time priority leads to the "best" price schedule, one which is "better" than that obtained from quote-driven institutions where brokers submit schedules first. This may explain the institutional structure of the NYSE.
