What Is Money?

Money is a system of value that facilitates the exchange of goods in an economy. Using money allows buyers and sellers to pay less in transaction costs, compared to barter trading.

The first types of money were 澳洲幸运5官方开奖结果体彩网:commodities. Their physical properties made them desirable as a medium of exchange. In contemporary markets, money can include government-issued 澳洲幸运5官方开奖结果体彩网:legal tender or 澳洲幸运5官方开奖结果体彩网:fiat money, money substitutes, fiduciary media, or electronic 澳洲幸运5官方开奖结果体彩网:cryptocurrencies.

How Money Works

Money is a 澳洲幸运5官方开奖结果体彩网:liquid asset used to facilitate transactions of value. It is used as a 澳洲幸运5官方开奖结果体彩网:medium of exchange between individuals and entities. It's also a 澳洲幸运5官方开奖结果体彩网:store of value and a 澳洲幸运5官方开奖结果体彩网:unit of account that can measure the value of other goods.

Prior to the invention of money, most economies relied on 澳洲幸运5官方开奖结果体彩网:bartering, where individuals would trade the goods they had directly for those thꦑat they needed. This raised the problem of the double coincidence of wants:🔯 a transaction could only take place if both participants had something that the other needed. Money eliminates this problem by acting as an intermediary good.

The first known forms of money were agricultural commodities, such as grain or cattle. These goods were in high demand and traders knew that they would be able to use or trade these goods again in the future. Cocoa beans, cowrie shells, and agricultural tools have also served as early forms of money.

As economies became more complex, money was standardized into 澳洲幸运5官方开奖结果体彩网:currencies. This reduced transaction costs by making it easier to measure and compare value. Also, the representations of money became increa💟singly abstract, from precious metals and stamped coiಞns to paper notes, and, in the modern era, electronic records.

What Are the Properties of Money?

In order to be most useful, money should be fungible, durable, portable, recognizable, and stable. These properties reduce the transaction cost ဣ;❀of using money by making it easy to exchange.

Money Should Be Fungible

The word fungible refers to a quality that﷽ allows one thi🐼ng to be exchanged, substituted, or returned for another thing, under the assumption of equivalent value. Thus, units of money should be interchangeable with one another.

For example, metal coins should have a standard weight and purity. Commodity money should be relatively uniform in quality. Trying toไ use a non-fungible good as money results in transaction costs that involve individually evaluating each unit of the good before an exchange can take place.

Money Should Be Durable

Money should be durable enough to retain its usefulness for many, future exchanges. A perishable good or a good that degrades quickly due to various exchanges will be less useful for future transactions. Trying to use a non-durable good as money conflicts with money's essential future-oriented use and value. 

Money Should Be Portable

Money should be easy to carry and divide so that a worthwhile quantity can be carried on one's person or transported. For example, trying to use a good that's difficult or inconvenient to carry as money could require physical transportation that results in transaction costs.

Money Should Be Recognizable

The authenticity and quantity of the good should be readily apparent to users so that they can easily agree to the terms of an exchange. Using a non-recognizable good as money can result in transaction costs relating to authenticating the goods and agreeing on the quantit🉐y needed for an exchange. 

Money's Supply Should Be Stable

The supply of the item used as money should be relatively constant over time to prevent fluctuations in value. Using a non-stable good as money produces transac♊tion costs due to the risk that its value might rise or fall, because of scarcity or over-abundance, before the next transaction.

How Is Money Used?

Money primarily functions as the good people use for exchanges of items of value. However, it also has seco💞ndary functions that derive from its use as a medium of exchange.

Money As a Unit of Account

Due to money's use as a medium of exchange for buying and selling and as a value indicator for all kinds of goods and services, money can be used as a unit of account.

That means money can keep track of changes in the value of items over time🎉 and multiple transactions. People can use it to compare the values of various combinations 💞or quantities of different goods and services.

Money as a unit of account makes it possible to account for profits 🧸and losses, balance a budget, and value the total assets of a company.

Money As a Store of Value

Money's usefulness as a medium of exchange in transactions is inherently future-oriented. As such, it provides a means to store a monetary value for use in the future without having that value deteriorate.

So, when people exchange items for money, that money retains a pa🃏rticular value that can be used in other transactions. This ability to function as a store of value fac🅺ilitates saving for the future and engaging in transactions over long distances. 

Money As a Standard of Deferred Payment

To the extent t🐻hat money is accepted as a medium of exchange and serves as a useful store of value, it can be used to transfer value over different tꦍime periods in the form of credits and debts.

One person can borrow a quantity of money from someone else for an agreed-upon pe💞riod of time, and repay a different agreed-upon quantity of money at a future date.

Different Types of Money

Market-Determined Money

Money can originate out of the spontaneous order of markets. As traders barter for various goods, some goods will prove more convenient than others because they have the best combination of the five propertℱies of money listed above.

Over t🌊ime, these goods may become desirable as objects of exchange, rather than for practical use. Eventually, people may come to desire a good solely for future trading.

Historically, precious metals such as gold and silver were often used as market-determined monies. They were highly prized across many different cultures and societies. Today, people in cashless economies frequently turn to cigarettes, instant noodles, or other nonperishable goods as a market-determined money substitute.

Government-Issued Currency

When a certain type of money is widely accepted throughout an 🐼economy, government bodies may begin regulating it ওas a currency. They may issue standardized coins or notes to further reduce transaction costs.

A government may also recognize some money as a 澳洲幸运5官方开奖结果体彩网:legal tender, meaning that courts and government bodies must accept thꦡat form of🦂 money as a final means of payment.

Issuing money allows the government to benefit from 澳洲幸运5官方开奖结果体彩网:seigniorage, the difference between the face value of ♋a currency and the cost to produඣce it.

For example, if the cost of printing a $100 bill is only $10, the government will earn a $90 profit for each bill it prints. However, governments that rely too heavily on seigniorage may inadvertently debase their currency.

Fiat Currency

Many c༺ountries issue fiat currency, which is currency that does not represent any type of commodity. Instead, fiat money is backed by the economic strength of the issuing🐓 government. It derives its value from supply and demand and the stability of the government.

Fiat money allows the issuing government to conduct economic policy by 澳洲幸运5官方开奖结果体彩网:increasing or reducing the money supply. In the U.S., the 澳洲幸运5官方开奖结果体彩网:Federal Reserve and the 澳洲幸运5官方开奖结果体彩网:Treasury Department monitor several types of money supplies for the purpose of regulating and mitigating monetary issues.

Since fiat money does✃ not represent a real commodity, it falls to the ♔issuing government to ensure that it meets the five properties of money outlined above.

The 澳洲幸运5官方开奖结果体彩网:International Monetary Fund (IMF) and 澳洲幸运5官方开奖结果体彩网:World Bank serve as global watchdogs for the exchange of international currencies. Governments may enact capital controls or establish pegs in ord🌸er 𒁏to stabilize their currency on the international market.

Money Substitutes and Fiduciary Media

To reduce the burden of carrying large quantities of currency, merchants and traders sometimes exchange money substitutes such as written statements of deb🥃t that can be redeemed later. These statements🍃 can themselves adopt some of the properties of money, particularly if traders use them in lieu of actual currency.

For example, ancient banks issued bills of exchange to their depositors, stating the amount that had been deposited and the terms for redemption. Rather than withdraw money from the bank to make payments, depositors would simply trade their bills, allowing the recipient to redeem or trade them at will.

This use of money substitutes can increase the portability and durability of money, as well as reduce the cost of storage. However, there are risks involved with money substitutes. Banks may print more bills than they have money to redeem, a practice known as 澳洲幸运5官方开奖结果体彩网:fractional reserve banking. If too many people try to make withdrawals at the same time, the bank may suffer from a bank run.

Fiduciary media are types of money substitutes introduced into circulation that aren't fully backed by the base money held to back money substitutes. For example, paper checks, token🍎 coins, and electronic credit re🔯present contemporary examples of fiduciary media.

Cryptocurrencies As Money

In recent years, digital currencies that do not exist in physical form, such as Bitcoin, haꦰve been introduced. Unlike electronic bank records or payment systems, these virtual currencies are not issued by a government or other central body. Cryptocurrencies have some of the properties of money and are sometimes used in online transactions.

Although cryptocurrencies are rarely used in everyday transactions, they have achieved some utility as a speculative investment or a store of value. Some jurisdictions have recognized cryptocurrencies as a payment medium, including the 澳洲幸运5官方开奖结果体彩网:government of El Salvador.

The Bottom Line

Money is some item of value that allows people and institutions to engage in transactions that result in an exchange of goods or serviಞces.

Money has to be exchangeable, convenient to carry, recognized as legitimate by all, physically long-lasting, and have a value that's stable.

Money comes in various forms, including precious metals, currencies, and money substitutes. At this time, though cryptocurrencies have some of the properties of money, they function without a central authority and aren't backed by governments. While cryptocurrencies (such as Bitcoin) are considered property for tax purposes by the IRS, they aren't considered legal tender by the U.S. government.
