To explore the relationship between the variables of interest, ARDL Bound testing approach of Pesaran and Shin (1999) was used. The empirical results show that corruption negatively affects long-term economic performance. And suggest that public investment large scale is not necessarily desirable in an environment characterized by corruption, because it results in a waste of public funds. However the estimation of an ECM model of short-term dynamics shows that corruption is associated with an increase in real GDP per head. The results support the idea that corruption undermines long-term economic performance and call for institutional reforms to improve the quality of governance as a prerequisite for extensive economic growth. Keywords: Corruption, Economic Growth, Investment, Cointegration, ARDL, ECM. Résumé Cette étude porte sur la relation entre la corruption et la croissance économique en Tunisie de 1987 à 2013, et s’intéresse essentiellement au rôle du pouvoir discrétionnaire et de la distorsion dans les dépenses publiques. Pour explorer la relation entre les variables d’intérêts, l’approche de cointégaration ‘’d’ARDL Bound testing’’ de Pesaran et Shin(1999) a été utilisée.
