This paper sets up a Gibbs sampler for a three state Markov switching model with non-constant transition probabilities. The step from two to three states is accomplished by the use of a multinomial probit model for the latent variable process. The algorithm is then applied to Swiss GDP data in...

The paper studies the interaction between cyclical uncertainty and investment in a stochastic real option framework where demand shifts stochastically between three different states, each with different rates of drift and volatility. In our setting the shifts are governed by a three-state Markov...
