For example, an increase in the money supply, a variable, will cause the price level, a variable, to increase but will have no long-run effect on the quantity of goods and services the economy can produce, a variable. The distinction between real variables and nominal variables is known as:

nominal, real, & the classical dichotomy

Explanation:

A nominal variable is a value whose values are non-numeric for example gender. It is calculated based on the current – year prices.

In other words, nominal value is calculated in monetary terms, whereas real value is measured on the basis of goods or services

A real variable is a variable whose values are numeric. It is measured based on the currency of the base year.

The distinction between real variables and nominal variables is known as nominal, real, & the classical dichotomy.

The Classical Dichotomy is based on the assumption that states that in the long run, the nominal economy and the real economy are completely separated from each other. In the long run, nominal prices have no impacts on real variables.
