August 2013The Twilight Zone: OTC Regulatory Regimes and Market Quality
with Ulf Br├╝ggemann, Christian Leuz, Ingrid M. Werner: w19358
We analyze a comprehensive sample of more than 10,000 U.S. OTC stocks. We provide much needed descriptive evidence on this market and show that the OTC market is a large, diverse, and dynamic trading environment with a rich set of regulatory and disclosure regimes, comprising venue rules and state laws beyond SEC regulation.

Focusing on two periods around the 1973 switch from fixed to floating exchange rates, we find a significant increase in the volatility of U.S. multinational monthly stock returns corresponding to the period of increased exchange rate variability. This increase in stock return volatility is also significant relative to the increase in stock return volatility for firms in three control samples. Using a single factor market model, we show this increase in total volatility led to a significant increase in market risk...
