In this paper we develop a general framework to analyze state space models with time-varying system matrices where time variation is driven by the score of the conditional likelihood. We derive a new filter that allows for the simultaneous estimation of the state vector and of the time-varying...

Most papers in the portfolio choice literature have examined linear predictability frameworks based on the idea that … simple but flexible Vector Autoregressive (VAR) models can be expanded to produce portfolio allocations that hedge against … simple Markov switching, by studying the effects of expanding both the order of the VAR and the number/selection of predictor …

In this paper we examine the issue of asymmetry in the return and volatility spillover effects from the US equity market into the Canadian and Mexican equity markets. We model the conditional volatility of the returns in each of the three markets using the asymmetric power model of Ding, Granger...

We observe that daily highs and lows of stock prices do not diverge over time and, hence, adopt the cointegration concept and the related vector error correction model (VECM) to model the daily high, the daily low, and the associated daily range data. The in-sample results attest the importance...
