Using my methods (SLS2 & SLS3) in estimating the system of simultaneous equations for the Iraqi economy for the period (1991-2021)

Abstract

In this study, Vladimir shed light on the methods of estimating the structural parameters of a system of simultaneous equations, which are each of the two-stage linear circuit methods, limits, and a method of the three-stage linear circuit method. The methods used were derived to join their estimators, and on the experimental side, they were adopted. On the average statistical criteria, the elastic deviation of the Euclidean distance , the Akaike information criterion AIC, and the entropy H(e) for light methods for the first simultaneous equations, assuming different values for the parameters and small, medium, and large sample sizes, the study reached the best method for major linear divisions. Three stages in the simultaneous equations. As for the applied side, a wide-ranging three-stage oil method was applied, the best of which appeared in the experimental side on real data related to the descriptive analysis of economic variables in Iraq (GDP - total profit - investment - moderate rate - interest rate - income). - Expenditures - Revenues - Money supply (for the period (1990-2021) through a direct study of the direct impact (production, exports, imports, inventory, etc.) of Lebanon’s impact of this benefit from the Iraqi economic system on the Iraqi economy. The study reached an Iraqi economic model. In second equations, their effectiveness has been proven through many economic and statistical indicators, as well as the superiority of the three-stage major integrals method in estimating simultaneous equations, as well as obtaining estimates that are consistent with economic theory and with landscape reality, reinforcing the basic outlook.
