The most important insight of the model is that adjustment lags in some parts of the economy can induce compensating volatility in others; specifically, when an exogenous variable changes, the short-term effect on the exchange rate can be greater than the long-run effect, so in the short term, the exchange rate overshoots its new equilibrium ...
In foreign exchange, a relevant factor would be the rate of change of the foreign currency spot exchange rate. A variance, or spread, in exchange rates indicates enhanced risk, whereas standard deviation represents exchange-rate risk by the amount exchange rates deviate, on average, from the mean exchange rate in a probabilistic distribution. A ...
This model can account for real exchange rate volatility, but does not say anything about the volatility of relative to output or the persistence of the real exchange rate movements. Chari , Kehoe and McGrattan (2002) [ 2 ] showed how a model with two countries and where prices were only allowed to change once-a-year had the potential to ...

[6] There is even a VIX on VIX (VVIX) which is a volatility of volatility measure in that it represents the expected volatility of the 30-day forward price of the CBOE Volatility Index (the VIX).

For example, for bond options [3] the underlying is a bond, but the source of uncertainty is the annualized interest rate (i.e. the short rate). Here, for each randomly generated yield curve we observe a different resultant bond price on the option's exercise date; this bond price is then the input for the determination of the option's payoff.
