In economics, deflation is an increase in the real value of the monetary unit of account, as reflected in a decrease in the general price level of goods and services exchanged, measurable by broad price indices.

Stagflation is the combination of high inflation, stagnant economic growth, and elevated unemployment. The term stagflation, a portmanteau of "stagnation" and "inflation", was popularized, and probably coined, by British politician Iain Macleod in the 1960s, during a period of economic distress in the United Kingdom. It gained broader recognition in the 1970s after a series of global economic shocks, particularly the 1973 oil crisis, which disrupted supply chains and led to rising prices and slowing growth. Stagflation challenges traditional economic theories, which suggest that inflation and

In monetary economics, redenomination is the process of changing the face value of banknotes and coins in circulation. It may be done because inflation has made the currency unit so small that only large denominations of the currency are in circulation. In such cases the name of the currency may change or the original name may be used with a temporary qualifier such as "new". Redenomination may be done for other reasons such as changing over to a new currency such as the Euro or during decimalisation.

thumb|400px|Starting with Nero in AD 64, the Romans continuously debased their silver coins until, by the end of the 3rd century, hardly any silver was left. A debasement of coinage is the practice of lowering the intrinsic value of coins, especially when used in connection with commodity money, such as gold or silver coins, while continuing to circulate it at face value. A coin is said to be debased if the quantity of gold, silver, copper or nickel in the coin is reduced.

Indexation is a technique to adjust income payments by means of a price index, in order to maintain the purchasing power of the public after inflation, while deindexation is the unwinding of indexation. It is often used to make sure regular payments, such as pension payments keep pace with inflation, so that they have the same value in real terms over time.

Reflation is used to describe a return of prices to a previous rate of inflation. One usage describes an act of stimulating the economy by increasing the money supply or by reducing taxes, seeking to bring the economy (specifically the price level) back up to the long-term trend, following a dip in the business cycle. It is the opposite of disinflation, which seeks to return the economy back down to the long-term trend.

Biflation (sometimes mixflation, indeflation, or compartflation) is a state of the economy, in which the processes of inflation and deflation occur simultaneously in different parts of the economy. The term was first coined in 2003 by F. Osborne Brown, a senior financial analyst at Phoenix Investment Group, and has later been widely used in the media. During the biflation, there is a simultaneous rise in prices (inflation) for commodities bought out of the basic income (earnings), and a parallel fall in prices (deflation) for goods bought mainly on credit. Biflation may be seen in the CPI comp

Agflation (or agrarian inflation) is an economic phenomenon of an advanced increase in the price for food and for industrial agricultural crops when compared with the general rise in prices or with the rise in prices in the non-agricultural sector. The term was increasingly used in the analytical reports, for example, by the investment banks Merrill Lynch in early 2007 and Goldman Sachs in early 2008. They used the term to denote a sharp rise in prices for agricultural products, or, more precisely, a rapid increase in food prices against the background of a decrease in its reserves, a relative

In statistics, a deflator is a value that allows data to be measured over time in terms of some base period, usually through a price index, in order to distinguish between changes in the money value of a gross national product (GNP) that come from a change in prices, and changes from a change in physical output. It is the measure of the price level for some quantity. A deflator serves as a price index in which the effects of inflation are nulled. It is the difference between real and nominal GDP.
