Inflation

An increase in prices.

The number of dollars in circulation exceeds the amount of goods and services available for purchase; inflation results in a decrease in the dollar's value.

A condition of increasing prices. Inflation is generally measured by the Consumer Price Index.

Inflation is a persistent increase in prices, often triggered when demand for goods is greater than the available supply or when unemployment is low and workers can command higher salaries.

Moderate inflation typically accompanies economic growth. But the US Federal Reserve Bank and central banks in other nations try to keep inflation in check by decreasing the money supply, making it more difficult to borrow and thus slowing expansion.

Hyperinflation, when prices rise by 100% or more annually, can destroy economic, and sometimes political, stability by driving the price of necessities higher than people can afford.

Deflation, in contrast, is a widespread decline in prices that also has the potential to undermine the economy by stifling production and increasing unemployment.

The simultaneous increase of consumer prices and decrease in the value of money and credit.

The loss of purchasing power that results from a general increase in the price of goods and services.

A rapid, accelerating expansion occuring in the early universe in some cosmological models, which solves several problems of cosmology.
