The Impact of Determinants of Investment on the Iraqi Economy for the Period (2004-2018), A Standard Study

Abstract

The research aims to measure and analyze the determinants of investment in the Iraqi economy and study the theoretical foundations of investment and analyze the viewpoint of the most important schools of economic thought regarding investment and investment determinants and their effects on economic activity, and by using possible standard models as the results of standard analysis using the joint integration tests of time series. Cointegration tests, they have proven the existence of a long-term equilibrium relationship according to the methodology of the results of estimating the short and long-term parameters and the error correction parameter(ECM), it is moving from a set of explanatory variables towards The dependent variable, while the value of the error correction vector coefficient was negative and significant, as it reached (-0.59%), which means the fulfillment of the two basic conditions in this parameter , namely : its negative value and the statistical significance . This means that (0.59) of the short-term errors are automatically corrected during the unit of time (year) to reach the equilibrium in the long term, meaning that the investment requires about less then a year (1.6), that is, approximately a year and 6 days to reach its equilibrium value in the long term, In other words, the previous period deviates from the long-term equilibrium and is corrected in the current by (59%). This indicates that the adjustment in the model was relatively fast.
