Purchasing power parity in an emerging market economy: a long-span study for Chile

Abstract

Recent research has found evidence that supports the purchasing power parity (PPP) condition in developed countries using very long-span data, while evidence for developing countries is almost nonexistent. This paper tries to fulfill this void by testing the validity of PPP as a long run equilibrium condition for Chile, using data, since its birth as a nation, developed by Díaz, Lüders and Wagner (2003). A battery of unit-root and cointegration tests is applied. We found evidence in favor of PPP. Results are robust to changes in the domestic price index, to changes in the sample period, and to the econometric technique applied.
