Information about Money Illusion
Money illusion refers to the tendency of people to think of currency in nominal, rather than real, terms. In other words, people mistake nominal variables for real variables. The term was coined by John Maynard Keynes in the early twentieth century, and Irving Fisher wrote an important book on the subject, Money Illusion, in 1928. The existence of money illusion is disputed by monetary economists who contend that people act rationally (ie think in real prices) with regard to their wealth. Shafir, Diamond and Tversky (1997) have provided compelling empirical evidence for the existence of the effect and it has been shown to affect behaviour in a variety of experimental and real world situations.
It has been contended that money illusion influences economic behaviour in three main ways:
Some have suggested that money illusion implies that the negative relationship between inflation and unemployment described by the Phillips curve might hold, contrary to recent macroeconomic theories. If workers use their nominal wage as a reference point when evaluating wage offers, firms can keep real wages relatively lower in a period of high inflation as workers accept the seemingly high nominal wage increase. These lower real wages would allow firms to hire more workers in periods of high inflation.
Explanations of money illusion generally describe the phenomenon in terms of heuristics. Nominal prices provide a convenient rule of thumb for determining value and real prices are only calculated if they seem highly salient (eg. in periods of hyperinflation or in long term contracts).
A heuristic is a method for helping in solving of a problem, commonly informal. It is particularly used for a method that often rapidly leads to a solution that is usually reasonably close to the best

It has been contended that money illusion influences economic behaviour in three main ways:
- Price stickiness. Money illusion has been proposed as one reason why nominal prices are slow to change even where inflation has caused real prices or costs to rise.
- Contracts and laws are not indexed to inflation as frequently as one would rationally expect.
- Social discourse, in formal media and more generally, reflects some confusion about real and nominal value.

Inflation is measured as the growth of the money supply in an economy, without a commensurate increase in the supply of goods and services. This results in a rise in the general price level as measured against a standard level of purchasing power.

hyperinflation is inflation that is "out of control," a condition in which prices increase rapidly as a currency loses its value. No precise definition of hyperinflation is universally accepted. One simple definition requires a monthly inflation rate of 20 or 30% or more.
