The purpose is to examine to what extent an increase in government spending affects the deterioration of terms of trade and contributes to increasing external imbalances. Econometric methods for heterogeneous panel data models are used to analyse the existence of a long-run relationship between the fiscal deficit and the current account. The empirical findings indicate that the twin deficits hypothesis is not confirmed for the whole European Union, but only for a certain number of member states, where a long-run relationship still exists, confirming the impact of the fiscal deficit on the current account. eng Josifidis, Kosta Dragutinović Mitrović, Radmila Bodor, Slađana
