A Theory of Participation in OTC and Centralized Markets, with Jérôme Dugast and Semih Üslü.

Are OTC markets too large relative to centralized trading venues?

Revised version: the least sophisticated investors optimally participate in an OTC market as customers, even when they have the option to join a centralized market: although they receive worse terms of trade in the OTC market, they benefit from the intermediation services provided by the most sophisticated investors, who optimally participate in the OTC market as dealers. We find that more customers should participate in the centralized market, and more dealers in the OTC market.
