The change in real interest rate persistence in OECD countries: evidence from modified panel ratio tests

This study examines whether real interest rates exhibit changes in persistence for a panel of Organization of Economic Cooperation and Development countries. The findings show that for long-term real interest rates there are changes in persistence from I(0) to I(1). For short-term real interest rates, the results display the absence of changes in persistence, while under cross-sectional dependence there is only weak evidence of changes in persistence from I(1) to I(0). The evidence of changes in persistence when the direction is considered unknown is even weaker.
