Tunisian Financial System: a Growth Factor

The relationship between financial development and economic growth were the subject of many recent theorical and empirical works [Shepherd, Hasan and Klapper, 2004; Gylfason, 2004; Rioja and Valev, 2003; Driffill, 2004; Haas, 2002; Carlin and Mayer, 2000]. These authors generally focused their analysis of the link finance- growth on the mature financial systems. As the Tunisian economy knew a long period of financial repression before starting the phases of liberalization, it would be more judicious to start by McKinnon and Shaw’s theory of “financial deepening” (1973) to then determinate the impact of Tunisian financial system development on economic growth. Indeed, McKinnon and Shaw were the first authors to analyze positive effects of financial liberalization policy on economic performance of less developed countries. To check the relevance of this assumption in Tunisian’s context, we built a model inspired of the model of King and Levine (1993) who by measuring instruments of economic and financial development appears good indicators of Tunisian economy’s financiarisation. The results of the empirical study on Tunisia stemming from causality tests within B-VAR framework nuance McKinnon and Shaw’s theorical contribution. Reciprocal relationships are only finding between the ratio of investment on the GDP and the loans granted to private and public sectors. The economic role of State is highlighted, over the period of pre-reforms as well as during the recent time.
