In this article, I first extend the standard unobserved-component time series model to include Hamilton's Markov-switching heteroscedasticity. This will provide an alternative to the unobserved-component model with autoregressive conditional heteroscedasticity, as developed by Harvey, Ruiz, and Sentana and by Evans and Wachtel. I then apply a generalized version of the model . In this article, I first extend the standard unobserved-component time series model to include Hamilton’s Markov-switching heteroscedasticity.

Journals & Books; Help Download PDF The more conventional way of testing for financial time series heteroskedasticity is to consider ARCH-type volatility models, which allow constant unconditional volatility but time-varying conditional volatility. We consider an appropriately specified Markov switching unobserved component model as a. We specify a time-series model for real GNP and consumption in which the two share a common stochastic trend and transitory component, and Markov-regime switching is used to model business cycle. unobserved component model with Markov-switching heteroscedasticity (UC-MS model). The U.S market crash in was unusual from different aspects. This crash was the biggest one in indexes; only in one day, there was such a crash, unprecedented from , and it suddenly increased stock price fluctuations. Later, Schwert () showed. This paper uses an unobserved component model with heteroskedastic disturbances based on Harvey et al. () to measure the time-varying importance of permanent and transitory components in the U.S. house prices. Our findings show that the cyclical component in the U.S. housing market is highly persistent and house prices were more than .

Exact formulae are provided for the calculation of multivariate skewness and kurtosis of Markov-switching Vector Auto-Regressive (MS VAR) processes as .
