A stochastic volatility model where volatility was driven solely by a latent variable called news was estimated for … volatilities. Volatility persistence being close to one was consistent with both volatility clustering and mean reversion … specification improvements were always possible. The model corroborated stylized findings in volatility modeling and has potential …

Using data for the major currencies from 1973 to 1994, we apply recent tests of asset price volatility to re …. Consistent with previous evidence from regression-based tests, most of the models that we examine are rejected by our volatility … “volatility”, however, may disguise the cause of rejection as excessive exchange rate volatility.

We study equity price volatility in general equilibrium with news shocks about future productivity and monetary policy … asset price volatility. We show that introducing news shocks in a canonical dynamic stochastic general equilibrium model may … not reduce asset price volatility under plausible parameter assumptions. This is because, in general equilibrium, the …

Statistical measures of the volatility of exchange rates, interest rates, and stock prices are estimated for a number … of countries. Periods of high volatility are identified and compared with periods of financial difficulty.
