A time series model for an exchange rate in a target zone with applications
Lundbergh, Stefan (contributor);  … - 2003 - [Elektronische Ressource]
In this paper we introduce a flexible target zone model that is capable of characterizing the dynamic behaviour of an exchange rate implied by the original target zone model of Krugman (1991) and its modifications. Our framework also enables the modeller to estimate an implicit target zone if it...

A nonlinear alternative to the unit root hypothesis
Eklund, Bruno (contributor) - 2003 - [Elektronische Ressource]
This paper considers testing the unit root hypothesis against a smooth transition autoregressive model as the alternative. The model specification makes it possible to discriminate between nonstationary random walk and stationary nonlinear processes. Some new limit results are presented,...

Common factors in conditional distributions
Granger, C. W. J. (contributor);  … - 2002 - [Elektronische Ressource]
The concept of common factors has in the econometrics literature been applied to conditional means or in some cases to conditional variances. In this paper we generalize this concept to bivariate distributions. This is done using the conditional bivariate copula as the statistical tool. The...

On seasonal error correction when the processes include different numbers of unit roots
Lyhagen, Johan (contributor); Löf, Mårten (contributor) - 2001 - [Elektronische Ressource], Rev. March 15, 2001
We propose a seasonal cointegration model [SECM] for quarterly data which includes variables with different numbers of unit roots and thus needs to be transformed in different ways in order to yield stationarity. A Monte Carlo simulation is carried out to investigate the consequences of...

An application of the analogy between vector ARCH and vector random coefficient autoregressive models
He, Changli (contributor); Teräsvirta, Timo (contributor) - 2002 - [Elektronische Ressource]
In this paper we derive conditions for the conditional covariance matrix to be positive definite in a general vector ARCH model. The conditions can be easily extended to the diagonal vector GARCH model. For the general vector GARCH model, analytical expressions for the conditions in terms of the...

Inference for unit roots in a panel smooth transition autoregressive model where the time dimension is fixed
He, Changli (contributor); Sandberg, Rickard (contributor) - 2005 - [Elektronische Ressource], Rev. February 18, 2005
In this paper we derive a unit root test against a Panel Logistic Smooth Transition Autoregressive (PLSTAR). The …, finite sample properties of the test are examined. We highlight scenarios under which the traditional panel unit root tests … by Harris and Tzavalis have inferior or reasonable power compared to our test. -- Dynamic nonlinear panel ; Smooth …
