PENENTUAN NILAI TUKAR: PENGUJIAN PURCHASING POWER PARITY DI INDONESIA

Abstract

This paper provides a test of purchasing power parity (PPP) as an explanation for longterm
foreign exchange rate movement. We impose symmetry and proportionality restrictions of
PPP to data drawn from the period 1969.1 through 2001.4. The tests are also run for sub-periods. Symmetry and proportionality restrictions find little support for the unit root tests though the Johansen test suggests that foreign exchange rate and inflation rate are linked in a long run sense. Error correction models are then estimated on the basis of the assumption that the United States inflation rate is exogenous. The error correction models result also rejects the PPP.
