    Like the consumer price index (CPI), the GDP deflator is a measure of price inflation/deflation with respect to a specific base year; the GDP deflator of the base year itself is equal to 100. Unlike the CPI, the GDP deflator is not based on a fixed basket of goods and services; the "basket" for the GDP deflator is allowed to change from year to ...

    en.wikipedia.org/wiki/Equation_of_exchange

    That is to say that, if and were constant or growing at equal fixed rates, then the inflation rate would exactly equal the growth rate of the money supply. An opponent of the quantity theory would not be bound to reject the equation of exchange, but could instead postulate offsetting responses (direct or indirect) of Q {\displaystyle Q} or of V ...

  9. Fisher equation - Wikipedia

    en.wikipedia.org/wiki/Fisher_equation

    The Fisher equation plays a key role in the Fisher hypothesis, which asserts that the real interest rate is unaffected by monetary policy and hence unaffected by the expected inflation rate. With a fixed real interest rate, a given percent change in the expected inflation rate will, according to the equation, necessarily be met with an equal ...
