The International Fisher effect is an extension of the Fisher effect hypothesized by American economist Irving Fisher. The Fisher effect states that a change in a country's expected inflation rate will result in a proportionate change in the country's interest rate (+) = (+) (+ []) where
Thus, the Fisher effect states that there will be a one-for-one adjustment of the nominal interest rate to the expected inflation rate. The implication of the conjectured constant real rate is that monetary events such as monetary policy actions will have no effect on the real economy—for example, no effect on real spending by consumers on ...
The risk-free rate is also a required input in financial calculations, such as the Black–Scholes formula for pricing stock options and the Sharpe ratio. Note that some finance and economic theories assume that market participants can borrow at the risk-free rate; in practice, very few (if any) borrowers have access to finance at the risk free ...
The formula effect accounts for the different formulas used to calculate the two indexes. The PCE price index is based on the Fisher-Ideal formula, while the CPI is based on a modified Laspeyres formula. The weight effect accounts for the relative importance of the underlying commodities reflected in the construction of the two indexes.
Econophysics is a non-orthodox (in economics) interdisciplinary research field, applying theories and methods originally developed by physicists in order to solve problems in economics, usually those including uncertainty or stochastic processes and nonlinear dynamics.
However, it does not provide a very deep analysis. The overall effects of a parallel change in the yield curve are supplied but there is none of the more detailed analysis supplied by a true fixed-income decomposition. A useful account of sector-based attribution, with worked examples, is provided in Dynkin et al. (1998).
