I study deviations from the law of one price in American Depositary Receipts (ADR) using tick-by-tick data from the United States and 22 different home markets from 2001 to 2016. Deviations persist, on average, 12 minutes, and mainly arise because of demand pressure. Exploiting institutional details that create exogenous variation in the impediments to arbitrage within and across days, I show that absolute price deviations predict illiquidity. Price deviations mainly predict the inventory costs component of the bid-ask spread. Thus, consistent with recent theory, these findings suggest that arbitrageurs in the ADR market tend to trade against demand pressure and enhance market integration and liquidity.
