The adaptive market hypothesis, as proposed by Andrew Lo is an attempt to reconcile economic theories based on the efficient market hypothesis (which implies that markets are efficient) with behavioral economics, by applying the principles of evolution to financial interactions: competition, adaptation, and natural selection. This view is part of a larger school of thought known as Evolu

A calendar effect (or calendar anomaly) is the difference in behavior of a system that is related to the calendar such as the day of the week, time of the month, time of the year, time within the U.S. presidential cycle, or decade within the century. It is most often used in a financial context to describe a market anomaly; traders may use market timing to profit from moves in stock pric

Chartalism is a heterodox theory in macroeconomics that views money as a pure creation of the state, introduced to control and organize economic activity rather than arising from barter or debt.

The coincidence of wants (often known as double coincidence of wants) is an economic phenomenon where two parties each hold an item that the other wants, so they exchange these items directly. Within economics, this has often been presented as the foundation of a bartering economy.

A currency is a standardized form of money used as a medium of exchange. Under this definition, the US dollar, the euro, the yen, sterling, and the renminbi are examples of (government-issued) fiat currencies. Currencies may act as stores of value and be traded between nations in foreign exchange markets, which determine the relative values of the different currencies.

The economy monetization is a metric of the national economy, reflecting its saturation with liquid assets. The level of monetization is determined both by the development of the national financial system and by the whole economy. The monetization of economy also determines the freedom of capital movement. Economists have long recognized the important role played by the money supply. Nev

Endogenous money is an economy’s supply of money that is determined endogenously—that is, as a result of the interactions of other economic variables, rather than exogenously (autonomously) by an external authority such as a central bank.

In economics, the law of one price (LOOP) states that in the absence of trade frictions (such as transport costs and tariffs), and under conditions of free competition and price flexibility (where no individual sellers or buyers have power to manipulate prices and prices can freely adjust), identical goods sold at different locations should be sold for the same price when prices are expr

In macroeconomic theory, liquidity preference is the demand for money, considered as liquidity. The concept was first developed by John Maynard Keynes in his book The General Theory of Employment, Interest and Money (1936) to explain the determination of the interest rate by the supply and demand for money.

Monetarism is a school of thought in monetary economics that emphasizes the role of policy-makers in controlling the amount of money in circulation. It gained prominence in the 1970s, but was mostly abandoned as a direct guidance to monetary policy during the following decade because of the rise of inflation targeting through movements of the official interest rate.

Monetary circuit theory is a heterodox theory of monetary economics, particularly money creation, often associated with the post-Keynesian school.

Monetary economics is the branch of economics that studies the nature, role, and impact of money and monetary institutions. It provides a framework for analyzing money and its core functions—as a medium of exchange, a store of value, and a unit of account—and examines how money can achieve widespread acceptance, including through its role as a public good.

Money is any item or verifiable record that is generally accepted as payment for goods and services and repayment of debts, such as taxes, in a particular country or socio-economic context. The primary functions which distinguish money are: medium of exchange, a unit of account, a store of value and sometimes, a standard of deferred payment.

Money creation, or money issuance, is the process by which the money supply of a country or economic region is increased. In most modern economies, both central banks and commercial banks create money. Central banks issue money as a liability, typically called reserve deposits, which is available only for use by central bank account holders. These account holders are generally large comm

In economics, nominal rigidity, also referred to as price stickiness or wage stickiness, describes a situation in which a nominal price is slow to adjust or resistant to change. Complete nominal rigidity occurs when a price remains fixed in nominal terms for a relevant period of time. For example, the price of a good may be contractually set at $10 per unit for an entire year, regardles

In economics, a price system is a system through which the valuations of any forms of property (tangible or intangible) are determined. All societies use price systems in the allocation and exchange of resources as a consequence of scarcity. Even in a barter system with no money, price systems are still utilized in the determination of exchange ratios (relative valuations) between the pr

Supply chain finance (SCF), also known as supplier finance or reverse factoring, comprises a suite of financial solutions that aim to manage working capital and liquidity for businesses within a supply chain. These arrangements are typically initiated by a buyer to allow their suppliers to access funding for their accounts receivable at interest rates based on the buyer's credit rating,

The wage unit is a unit of measurement for monetary quantities introduced by Keynes in his 1936 book The General Theory of Employment, Interest and Money (General Theory). A value expressed in wage units is equal to its price in money units divided by the wage (in money units) of a man-hour of labour.
