Editorial: Long-run purchasing power parity and real exchange rates: introduction and overview

Abstract

We introduce and summarize the results of 18 empirical studies that make up this special issue on long-run purchasing power parity (PPP) and real exchange rates. The motivation for the special issue was to bring together a set of studies as diverse as possible in terms of countries, real exchange rates and methodology, as a means of testing the robustness of long-run PPP. Overall, the results of the various studies provide robust support for long-run PPP.

Notes

¹For surveys of this literature see MacDonald and Taylor (1992), Taylor (1995) and Taylor and Taylor (2004).

²The importance of using long spans of data in order to enhance test power in testing for long-run PPP is stressed by Lothian and Taylor (1996, 2000, 2008).
