The anatomy of financial crises: Evidence from the emerging ADR market

We study the anatomy of recent financial crises in Mexico, East Asia, Russia, Brazil, Turkey, and Argentina by investigating the efficiency and pricing of the emerging American depositary receipt (ADR) market. We use a non-parametric technique to test for persistent regime shifts in two basic structural relationships for ADR returns in 20 emerging countries -- identified via arbitrage and capital mobility considerations -- that should always hold in efficient and integrated capital markets. We find that those "normal" market conditions were instead often violated in proximity of financial crises: The law of one price often weakened (by 54% on average) and domestic sources of risk became more important (often by more than 100%) for many emerging ADRs. We also find the likelihood of these regime shifts to be related to proxies for uncertainty among investors, exchange rate volatility, trade linkages, and liquidity (but not stock market trends, currency devaluations, capital flight, or capital controls).
