We show that many-to-one matching markets with contracts where colleges’ preferences satisfy the hidden substitutes condition of Hatfield and Kominers (2015)may not be embedded, in the sense of Echenique (2012)into a Kelso and Crawford(1982)matching-with-salaries market. Our proof relies on a configurations of preferences that is observed in many college admissions markets.
