Program and Data Files

This program replicates the empirical work reported in the above paper.

There are two Gauss programs, one for the Markov switching mean AR(p) model of Hamilton (1989), and one for the Markov switching parameter model as presented in the above paper.

The programs estimate the model, and test the null hypothesis of a single regime against the alternative of two regimes.
