Panel data are increasingly being used in both macro- & micro-level studies of economic problems. Macro-panel data (i denotes countries) are characteristic by sufficiently long time series to be able to analyze panel spurious regression & panel cointegration. According to the main stream of the economic theory the budget deficits leads to deterioration in the current account balance. The panel long-run causal relation is examined in the case of the four groups of countries. For the Granger causality test the panel cointegration analysis is needed. The panel cointegration relationships were not found in any case. Some similarities in the panels were found in the case of Latin America countries but they are not significant.
