Aggregate price indexes, cointegration, and tests of the purchasing power parity hypothesis

Author

Listed:
  • Johnson, Paul A.

Abstract

In this paper I show that cointegration tests of PPP using aggregate price indexes are not always robust to changes in relative prices. I offer a method of gauging the importance of these effects and find them to be unimportant in recent rejections of PPP.
