In this paper we present explanation on the phenomenon pointed out in Cook and Manning (2002) on the unusual behaviour of the Dickey-Fuller test in the presence of trend misspecification. It appears that the rejection frequency of the unit root tests in the presence of trend misspecification is...

The present paper introduces the Bi-parameter Smooth Transition Autoregressive (BSTAR) model that generalizes the LSTR2 model, see Terasvirta (1998). In contrast to the LSTR2 model, which features the symmetric transition function, the BSTAR model is characterized by the asymmetric transition...

In this paper, we address the issue of spurious correlation in the production of health in a systematic way. Spurious correlation entails the risk of linking health status to medical (and nonmedical) inputs when no links exist. This note first presents the bounds testing procedure as a method to...

A bifactor model of the unobserved common leading and coincident indicators with Markov switching, introduced via the common factor intercept term, is examined. The model has four regimes and the lag between the leading and coincident factors is reflected in transition probabilities matrix....

This paper introduces a two-factor model of leading and coincident economic indicators. The common leading factor is assumed to Granger-cause the common coincident factor. This property is used to estimate the two common factors simultaneously and hence more efficiently. Two models of the latent...

This paper sets up a common unobserved factor model with smooth transition autoregressive dynamics. This model is compared to the already classical common factor model with regime-switching. Both models' in-sample and out-of-sample performance in terms of capturing and predicting the business...
