Bayesian analysis of output gap in Barbados

open access: yesLatin American Journal of Central Banking, 2020
This article contributes to understanding the performance of various unobserved components (UC) models in fitting Barbados’ real GDP. Relying on recent UC models techniques, it finds support for the UC model that captures correlated disturbances, but not

Approximate state space modelling of unobserved fractional components [PDF]

open access: yesEconometric Reviews, 2020
We propose convenient inferential methods for potentially nonstationary multivariate unobserved components models with fractional integration and cointegration. Based on finite-order ARMA approximations in the state space representation, maximum likelihood estimation can make use of the EM algorithm and related techniques. The approximation outperforms

Univariate unobserved-component model with a nonrandom-walk permanent component [PDF]

open access: yesApplied Economics, 2013
In this note, we revisit the univariate unobserved-component (UC) model of US GDP by relaxing the traditional random-walk assumption of the permanent component. Since our general UC model is unidentified, we investigate the upper bound of the contribution of the transitory component, and find it is dominated by the permanent component.
