Abstract

Time series are often subject to structural changes caused by external events such as strikes, new fiscal measures, or policy changes. In the current paper, we conduct a comparative study of a parametric and nonparametric approach to intervention time series modeling to model the impact, on corporate tax, of the important tax reform in December 2012 in Togo (the establishment of a Togolese Revenue Office).The comparison of the two models has led us to conclude that the non-parametric approach is superior in terms of predictive quality as well as the measurement of the effect of the reform.

Les séries temporelles sont souvent sujettes à des changements structurels causés par des événements externes tels que des grèves, de nouvelles mesures fiscales ou des changements de politique. Dans cet article, nous menons une étude comparative des approches paramétrique et non-paramétrique de l'analyse d'intervention afin de modéliser l'impact de l'importante réforme fiscale de décembre 2012 au Togo (mise en place de l'Office Togolais des Recettes) sur l'impôt sur les sociétés. La comparaison des deux modèles nous a amené à conclure que l'approche non-paramétrique est meilleure en terme de qualité prédictive ainsi que la mesure de l'effet de la réforme.
