Abstract

National debt has been identified as a major economic problem affecting the developing world in general where vital national resources are diverted from developmental functions to meeting debt obligations in interest and principal repayments.  A  multiplicity of literature  portraying the causes of the debt build up have tended to bring out petroleum imports as one key contributor to third world indebtedness. The study reanalyzes this proposition by studying the relative impact of the Zambian petroleum imports on its national debt as a decomposed General Macroeconomic Theoretical process utilizing a time-varying two state multivariate Markov-Switching Autoregressive Model (MSAR) with Zambian National Debt as the dependent variable and Petroleum imports, Non-Petroleum imports, Government Expenditures, Gross capital formation, Exports, Private Final Consumption and GDP as the regressors, using annual time series data from the early 1980’s to 2019. The study established  national debt reducing effects to have run from Petroleum imports, GDP, Gross capital formation and private consumption expenditures in both the dormant and expansive states of the model. Debt increasing effects were brought out to have run from Government expenditures and national exports in both states of the model. It was only from non-petroleum imports that results were inconclusive.
