Testing for real interest rate parity using panel stationarity tests with dependence: a note

Abstract

This paper tests for real interest parity (RIRP) among the nineteen major OECD countries over the period 1978:Q1-2006:Q1 using both short and long-run definitions of interest rates. Once the independence hypothesis is rejected among these series, we test for RIRP using panel data unit root and stationarity tests based on common factor models that allow for pervasive forms of dependence. Our results indicate that there is no evidence in favor of the weak version of the RIRP since one of the common factors that have been estimated is non-stationar
