Do People Really Have Inflation Expectations?

A common feature of macroeconomics is to run models assuming that individuals in the economy have inflation expectations. This flows naturally from assuming that they have rational expectations (can accurately predict the future and fully understand how the economy works).

The Money Illusion

What if I told you about an economic theory that assumed every person in the economy understood economic terms and kept up to date with the state of the economy? To be exact, what if I told you about a theory that assumed everyone in the economy based their decisions on the rate of inflation? You’d (rightly) say that was a daft and unrealistic assumption completely out of touch with how real people think. The reason for this is due to what is known as the Money Illusion.
