This research looks into the Fisher effect in the Korean market with the case-wise bootstrapping
method which was originally developed by Efron (1979). The strength of using
case-wise bootstrapping method, according to Davidson and Hinkley (1999), is the robustness
to nonnormality and heteroskedasticity. The main assumption of this research is
that there exists a structural break in the macroeconomic data of Korean economy, and
as mentioned by Hatemi-J (2011), it needs to be considered in order to find a full Fisher
effect. The Korean economy was critically affected by the East Asian financial crisis from
1997 to 1998, and this gives a good reason to assume a structural break in the Korean
market data. Although past Korean literatures have suggested its possible existence, it
was not tested in detail. This research examines the possibility of such break, and confirms
that there is a break in the Korean macroeconomic data. The empirical results from
this research show that the bootstrapping method gives accurate estimates of real interest
rates before and after the structural break point. However, the data showed that structural
breaks do not affect the relationship between the nominal interest rate and inflation and
the regression becomes distorted when the data directly related to the structural break period
are not excluded in the analysis. The main question is whether the Fisher effect can
be noticed before and after the structural break point, and it is shown in this study that
the Fisher effect cannot be found both before and after the structural break point. However,
the Fisher effect is discovered when no data are excluded, and the assumption of a
structural break is not necessary.
