A crucial task in the study of business cycle is the detection of the turning points, indicating the beginning (end) of a phase of growth (recession) of the economy. The dating proposed by experts are generally evaluated with the support of some empirical procedure. Many efforts have been devoted to propose statistical models able to detect the turning points and to forecast them. A class of models largely used for these purposes is the Markov Switching one. In this work we use a new version of the Markov Switching model, named Markov Switching model with latent information, which seems particularly able to detect the turning points in real time and to forecast them. In particular this model uses a latent variable, representing the cycle of the economy, as information to drive the transition probabilities from a state to another. Two examples are provided: in the first one we use Japanese GDP data, where our model and the classical Markov Switching model have a similar performance, but the first provides more information to forecast the turning points; in the second one we analyze USA GDP data, where the classical Markov Switching model fails in the turning points detection, whereas our model fits adequately the data.
