We study measures of foreign exchange rate volatility based on high-frequency (5-minute) $/DM exchange rate returns … using recent nonparametric statistical techniques to compute realized return volatility and its separate continuous sample … implied volatility. We find that implied volatility is an informationally efficient but biased forecast of future realized …
