Thus, the Autoregressive Distributed Time Lapse (ARDL) model was used to measure the effects in the long term and the short term. The study covered annual data for a time series spanning 32 years for the period (1990-2021), relying on official data issued by the World Bank (WB), the International Monetary Fund (IMF), and the Iraqi Ministry of Planning, the Central Organization for Statistics and Information Technology (COS).
