Entry and Exit in Treasury Auctions

Staff Working Paper 2024-29 Jason Allen, Ali Hortaçsu, Eric Richert, Milena Wittwer
This paper introduces and estimates a structural model of the Canadian primary market for government debt. We assess the role of dealer exit in this market as a key reason for increased, yet irregular, customer entry and quantify the benefits of greater customer competition against the costs of higher market volatility.

Intermediary Market Power and Capital Constraints

Staff Working Paper 2023-51 Jason Allen, Milena Wittwer
We examine how intermediary capitalization affects asset prices in a framework that allows for intermediary market power. We introduce a model in which capital-constrained intermediaries buy or trade an asset in an imperfectly competitive market, and we show that weaker capital constraints lead to both higher prices and intermediary markups.
