GRANVILLE, B. and MALLICK, S.K., 2004. Fisher hypothesis: UK evidence over a century. Applied Economics Letters, 11, pp. 87-90.
Using annual data over a long time horizon from 1900 to 2000 for the UK, this study finds the existence of a Fisher relation via Johansen cointegration tests. The cointegrating relationship between the two variables suggests a significant long-run equilibrium with a positive coefficient of more than one during the stated period.
