The dates of U.S. business cycle are reported by NBER with a considerable delay, so an early notion of turning points is of particular interest. This paper proposes a novel sequential approach designed for timely signaling these turning points. A directional cumulated sum decision rule is...

The 90’s could be characterized as a time in which both developed and emerging countries have su¤ered important episodes of exchange rate instability; some of these periods have resulted in exchange rate devaluations and others, in important exchange rate depreciations. We are interested in...

We propose testing for business cycle first-moment asymmetries in Markov-switching autoregressive (MS-AR) models. We derive the parametric restrictions on MS-AR models that rule out types of asymmetries such as deepness, steepness, and sharpness, and set out a testing procedure based on Wald...

We consider whether oil prices can account for business cycle asymmetries. We test for asymmetries based on the Markov switching autoregressive model popularized by Hamilton (1989), using the tests devised by Clements and Krolzig (2000). We select the transformation of the oil price of Lee, Ni...

This paper focuses on whether monetary policy has asymmetric effects. By building on the Markov switching model introduced by Hamilton (1989), we examine questions like: Does monetary policy have the same effect regardless of the current phase of economic fluctuations? Given that the economy is...

In this paper we propose a method to derive the spectral representation in the case of a particular class of nonlinear models: Markov Switching ARMA models. The procedure simply relies on the application of the Riesz-Fisher Theorem which describes the spectral density as the Fourier transform of...

Using Markov Switching Autoregressive models the behaviour of four crime variables and unemployment rate during the period of study is investigated and different regimes for each variable determined. Using some nonparametric measures such as the Concordance Index (Harding and Pagan, 2002) and...

In this paper we point out that using a two-state Markov chain to describe change in regime makes it difficult to interpret the model since there is a bias towards frequent shifts. However, by using a finite Markov chain with a transition matrix satisfying certain restrictions it is possible to...
