الارتباط الحركي بين الاستثمار في مؤسسات القطاع الحكومي والاستثمار الخاص عبر نموذج التقهقر الذاتي البنيوي: حالة الاقتصاد السعودي

The purpose of this paper is to analyze the relationship between investment in public sector institutions and private investment in the Saudi economy by using Structural VAR model for testing the dynamic crowding-out effect during the last four decades. Three fundamental variables are mobilized: the GDP, public investment and private investment. The linear relationship between structural shocks, which have an economic and financial interpretation, and the reduced random residuals has been established to evaluate the dynamic impacts. The findings show that the investment of the public sector institutions has an impact on the investment of private sector, and that the impulse response functions to the supply and demand shocks indicate that the crowding-out effect is verified in the short and long run.
