The achievement of an effective infrastructure, reliable and fair, is essential for economic growth. Indeed, the transport infrastructure is essential to the prosperity of regions. To investigate the relationship between transport infrastructure and economic growth, we use the autoregressive distributed lag model (ARDL), we find that transport infrastructure is cointegrated with economic performance, indicating the affirmed presence of long-run equilibrium relationships among them. We use annual data for the period from 1980 to 2013. The study found that the transport infrastructure and investment in transport infrastructure in Tunisia have a significant positive contribution to growth, which shows that each impact is strong and statistically significant. The Tunisian experience suggests that it is necessary to design an economic policy that will improve the transport infrastructure and to increase investment made to the sector for sustainable economic growth in Tunisia. It is necessary to improve the existing road and rail networks.

Abstract:The objective of this paper is to construct an index of financial liberalization for Tunisia using the Principal Component Analysis method over a period of 33 years from 1980 to 2012. The index indicates the degree of financial liberalization at any given time. This index is especially useful to control the pace of liberalization and evaluation of the effect of this policy on economic aggregates. This paper also includes partial measures of liberalization index. The constructed index shows that the process of financial liberalization in Tunisia is accelerated with the introduction of the structural adjustment program, during the period 1987 to 1994.
