Deviations from PPP and UIP in a financially open economy: the Turkish evidence.

This paper investigates the interrelations between purchasing power parity (PPP) and uncovered interest parity (UIP) in Turkey using Johansen cointegration analysis for a system containing Turkish and US inflation rates, interest rates, and exchange rate. The results of a structural model obtained by data-acceptable over-identifying restrictions over the cointegration space suggest the existence of two cointegration vectors representing UIP and PPP with proportionality and symmetry conditions, respectively. Consistent with the c apital en h anced e quilibrium e xchange r ates (CHEERs) approach, each of the international parity hypotheses is rejected when formulated independently. This is a theiry-consistent result for a financially open economy for which equilibrium conditions of asset and commodity markets may not be independent of each other. [ABSTRACT FROM AUTHOR]
