Özet:

The aim of the study is to explore the causality relationship between the budget balance and the current account balance of Turkey. Differently from the literature, the causality relationship is examined by considering the volatility of the variables in question. Accordingly, the multivariate GARCH (MGARCH) methodology for modelling the volatility and 1987-2005 quarterly data of Turkey are utilized. Depending upon the results of the selection criterion and autocorrelation tests, constant conditional correlation (CCC) model is determined as the appropriate MGARCH model for the analysis. The results of the Granger causality test applied on the CCC model find no evidence that supports the effect of the budget deficit on the current account deficit. Contrarily, the current account balance is found to be influential both on the budget balance and the volatility of the budget balance. Therefore it should be considered that the policies regarding the current account balance affects the budget balance as well.
