ARDL investment model of Tunisia

The paper investigates the determinants of investments in Tunisia using annual data over the period of 1961-2011. The importance of this study comes from the necessity to determine important factors influencing domestic investments in Tunisia. An Autoregressive Distributed Lag (ARDL) modeling is employed to investigate the impact of the gross domestic product, monetary base and trade openness on domestic investments. Our results reveal that there is an equilibrium relationship between investments and monetary base, the influence of the others is insignificant or rather ambiguous.
