Markov-switching models Highlights Markov-transition modeling Autoregressive model Dynamic regression model State-dependent regression parameters State So far in my studies, the word Markov comes across very often. Switching between states or regimes can be either abrupt or smooth. e. I am running a model on active-passive fiscal-monetary policy regimes. Markov-switching models are not limited to two regimes, although two-regime models are common. These changes are associated with Markov switching models are a popular family of models that introduces time-variation in the parameters in the form of their state- or regime The discrete state evolves through time as a discrete Markov chain and we can summarize its statistical properties by a transition probability matrix.

The Markov switching model of Hamilton (1989), also known as the regime switch-ing model, is one of the most popular nonlinear time series models in the literature. Markov switching with 2 states is a great tool for this. RPF, which does a Markov switching ARCH model is discussed in a separate section. One-step predictions One-step predictions in a Markov-switching model are the forecasted values of the dependent variable using one-step-ahead predicted probabilities.
