TÜRKİYE'DE DÖRDÜZ AÇIK HİPOTEZİNİN AMPİRİK ANALİZİ.

Current account balance deficits that exist in developed and developing countries have been the subject of research for many years. In the theoretical and empirical literature, there is a lot of research on the concept of twin deficit and triplet deficit. The importance of the output gap, which is the basis of the triple deficit, has been discussed in recent years. The positive interaction of relations between triplet deficits and output deficits is called the "quadruple deficits hypothesis". In this study, the presence of a quadruple deficit in Turkey in the period 1990-2019 is tested by VAR and Ganger casusality methods. While the findings provide evidence of the relationship between savings investment balance and output balance, the results of the Granger causality test show that there are no quadruple deficits in Turkey.
