Summary

The objective of this chapter is to study some methods and econometric models available in the literature for modeling the volatility of an asset return. The models are referred to as conditional heteroscedastic models. The univariate volatility models discussed in the chapter include the autoregressive conditional heteroscedastic (ARCH) model, the generalized ARCH (GARCH) model, the exponential GARCH (EGARCH) model, the threshold GARCH (TGARCH) model, the conditional heteroscedastic autoregressive moving-average (CHARMA) model, the random coefficient autoregressive (RCA) model, and the stochastic volatility (SV) models. The chapter discusses advantages and weaknesses of each volatility model and shows some applications of the models. It describes some alternative approaches to volatility modeling, including use of daily high and low prices of an asset.
