Yet the British experience (for short-term interest rates) examined by Foster (1979) suggests the opposite, and, following Hendershott and Hu (forthcoming), we have demonstrated that even with an unindexed tax system, if the risk premium on equities rises with inflation, then the pre-tax real rate of interest can remain constant when inflation changes. Evaluating the empirical validity of our assumption is not only difficult for the reasons indicated by Foster, but measuring the impact of the expected inflation rate on the pre-tax real rate of return is inherently difficult in a world of uncertainty.…”
