  2. 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 ...

  3. Fisher effect - Wikipedia

    en.wikipedia.org/wiki/Fisher_effect

    The equation states that the real interest rate (), is equal to the nominal interest rate minus the expected inflation rate (). The equation is an approximation; however, the difference with the correct value is small as long as the interest rate and the inflation rate is low.

  4. List of price index formulas - Wikipedia

    en.wikipedia.org/wiki/List_of_price_index_formulas

    It was inadequate for that purpose. In particular, if the price of any of the constituents were to fall to zero, the whole index would fall to zero. That is an extreme case; in general the formula will understate the total cost of a basket of goods (or of any subset of that basket) unless their prices all change at the same rate.

  5. Inflation - Wikipedia

    The inflation rate is most widely calculated by determining the movement or change in a price index, typically the consumer price index. [48] The inflation rate is the percentage change of a price index over time. The Retail Prices Index is also a measure of inflation that is commonly used in the United Kingdom. It is broader than the CPI and ...

  6. Macroeconomic model - Wikipedia

    en.wikipedia.org/wiki/Macroeconomic_model

    A macroeconomic model is an analytical tool designed to describe the operation of the problems of economy of a country or a region. These models are usually designed to examine the comparative statics and dynamics of aggregate quantities such as the total amount of goods and services produced, total income earned, the level of employment of productive resources, and the level of prices.

  7. IS/MP model - Wikipedia

    en.wikipedia.org/wiki/IS/MP_model

    An increase in the interest rate, from a leftward shift of the MP curve or higher level of inflation, produces lower total output, Q. The IS curve displays a negative relationship between the real interest rate, located on the vertical axis, and total output, on the horizontal axis.

    For example, if the inflation rate is 5%, on a one-year loan of $1,000 with an 8% nominal interest rate the real interest rate would be 8% minus 5% or 3%. The real interest rate will usually be ...

  9. Price level - Wikipedia

    en.wikipedia.org/wiki/Price_level

    The general price level is a hypothetical measure of overall prices for some set of goods and services (the consumer basket), in an economy or monetary union during a given interval (generally one day), normalized relative to some base set.
