Testing for a nonlinear Fisher relationship

Empirical evidence regarding the Fisher effect is mixed. One reason may be a nonlinear adjustment process in the real interest rate. The nonlinear unit root test proposed by Sollis, Leybourne, and Newbold (Journal of Money, Credit, and Banking 34: 686-700, 2002) is used to test for stationarity of the U.S. real interest rate over the 1934:01-2011:02 period and selected subperiods. The unit root null in the real rate of interest can be rejected over the full sample, evidence of a Fisher effect. Weaker evidence of a Fisher relation is found in the subsample for 1934:01-1959:12 for which the unit root null can be rejected for one measure of the real interest rate. However, there is no indication of a Fisher effect for subperiods starting in 1960 or later. A conjecture is that temporal aggregation of the interest rate data may explain the different results, but the findings are also consistent with other explanations.Fisher effect, nonlinear unit root, U.S. real interest rate
