THE IMPACT OF EXTERNAL PUBLIC DEBT ON THE NATIONAL ECONOMY'S KEY MACROECONOMIC INDICATORS (CASE OF UKRAINE)

The paper empirically explores the impact of external public debt in Ukraine on key macroeconomic indicators such as real GDP growth, real effective exchange rate, and current account balance. The problem of increasing external debt affects not only the problems of balance of payments fluctuations but also economic security and economic growth. We have tested the hypotheses regarding the impact of Ukraine's external public debt on these indicators in the short and long run. As an empirical tool for hypotheses testing vector autoregression models (VaR models) have been chosen. The results of constructed models show the acceleration of the external public debt growth provokes the GDP growth rate to fall with subsequent macrostabilization. The reaction of the GDP growth rate to the shock of the real effective exchange rate is more noticeable. The shock of real effective exchange rate has led to increase in external public debt with a further dampening to zero.Empirical data from the VaR model confirm that external debt has a negative impact on GDP and essentially behaves similarly to the shock of REER strengthening. Research results confirm the relationship between external public debt, real effective exchange rate, and GDP growth in Ukraine. Based on the models it was analyzed the external public debt and real effective exchange rate shocks influence the real gross domestic product growth rate. The growth of external public debt leads to the GDP growth rate fall by 1% during a year and a half with subsequent stabilization in the future. GDP growth fluctuations are explained mainly by their own fluctuations while external public debt is accounting for 2,5-8% of its fluctuations. Fluctuations in external public debt of 7-10% are explained by current account fluctuations in Ukraine. The described results of the model correspond to the concept of dependent economy.
