This paper investigates the nexus between financial sector development and economic growth in the Saudi economy over the period 1970-2012 by using four alternative proxies for financial development and several techniques including unit root tests, the co-integration test, the Granger Causality Test, and the Vector Error Correction Model (VECM). We used time series econometrics techniques to examine the causal relationship between financial sector development and economic growth in the Saudi economy. The results obtained from the analyses show that there is a positive relationship between financial sector development and economic growth in Saudi Arabia. The development of the financial system will thus have a positive impact on the growth of the Saudi economy.

This study investigates the causality relationship between defence expenditures and Non Oil economic growth in Saudi Arabia over the period 1970-2012. Using Unit root tests, Johansen's co-integration test and Granger Causality test. In this paper we found the existence of bi-directional causality relationship running from Non Oil-GDP to defence expenditure. The results show that, in Saudi Arabia, the model of defence expenditure is found to hold for Non Oil-GDP.
