. Ancient and medieval civilizations incorporated basic functions of finance, such as banking, trading and accounting, into their economies. In the late 19th century, the global financial system was formed. It was in the middle of the 20th century that finance emerged as a distinct academic discipline, separate from economics. (The first academic journal, '' The Journal of Finance'', began publication in 1946.) The earliest doctoral programs in finance were established in the 1960s and 1970s. Finance is widely studied at the undergraduate and masters level.


The financial system

As above, the financial system consists of the flows of capital that take place between individuals and households (

), and businesses ( corporate finance). "Finance" thus studies the process of channeling money from savers and investors to entities that need it. Savers and investors have money available which could earn interest or dividends if put to productive use. Individuals, companies and governments must obtain money from some external source, such as loans or credit, when they lack sufficient funds to operate. In general, an entity whose income exceeds its

can lend or invest the excess, intending to earn a fair return. Correspondingly, an entity where income is less than expenditure can raise capital usually in one of two ways: (i) by borrowing in the form of a loan (private individuals), or by selling government or corporate bonds; (ii) by a corporation selling equity, also called stock or shares (which may take various forms:

Areas of finance

As outlined, finance comprises, broadly, the three areas of personal finance, corporate finance, and public finance. These, in turn, overlap and employ various activities and sub-disciplines chiefly investments, risk management, and quantitative finance.


Personal finance

Personal finance is defined as "the mindful planning of monetary spending and saving, while also considering the possibility of future risk". Personal finance may involve paying for education, financing

. Personal finance may also involve paying for a loan or other debt obligations. The main areas of personal finance are considered to be income, spending, saving, investing, and protection. The following steps, as outlined by the Financial Planning Standards Board, suggest that an individual will understand a potentially secure personal finance plan after: * Purchasing insurance to ensure protection against unforeseen personal events; * Understanding the effects of tax policies, subsidies, or penalties on the management of personal finances; * Understanding the effects of credit on individual financial standing; * Developing a savings plan or financing for large purchases (auto, education, home); * Planning a secure financial future in an environment of economic instability; * Pursuing a checking and/or a savings account; * Preparing for retirement or other long term expenses.


Corporate finance

Corporate finance deals with the actions that managers take to increase the value of the firm to the shareholders, the sources of funding and the capital structure of corporations, and the tools and analysis used to allocate financial resources. While corporate finance is in principle different from managerial finance, which studies the

Public finance

Public finance describes finance as related to sovereign states, sub-national entities, and related public entities or agencies. It generally encompasses a long-term strategic perspective regarding investment decisions that affect public entities. These long-term strategic periods typically encompass five or more years. Public finance is primarily concerned with: * Identification of required expenditures of a public sector entity; * Source(s) of that entity's revenue; * The

Investment management

Investment management is the professional asset management of various securities typically shares and bonds, but also other assets, such as real estate, commodities and alternative investments in order to meet specified investment goals for the benefit of investors. As above, investors may be institutions, such as insurance companies, pension funds, corporations, charities, educational establishments, or private investors, either directly via investment contracts or, more commonly, via collective investment schemes like mutual funds, exchange-traded funds, or REITs. At the heart of investment management is

Risk management

Risk management, in general, is the study of how to control risks and balance the possibility of gains; it is the process of measuring risk and then developing and implementing strategies to manage that risk.

The discipline has two main areas of focus: See the discussion re finance theory by Fama and Miller under . asset pricing and corporate finance; the first being the perspective of providers of capital, i.e. investors, and the second of users of capital; respectively: * Asset pricing theory develops the models used in determining the risk-appropriate discount rate, and in pricing derivatives; and includes the portfolio- and investment theory applied in asset management. The analysis essentially explores how rational investors would apply risk and return to the problem of investment under uncertainty, producing the key " Fundamental theorem of asset pricing". Here, the twin assumptions of rationality and market efficiency lead to modern portfolio theory (the CAPM), and to the Black–Scholes theory for

aims to establish different market settings and environments to experimentally observe and provide a lens through which science can analyze agents' behavior and the resulting characteristics of trading flows, information diffusion, and aggregation, price setting mechanisms, and returns processes. Researchers in experimental finance can study to what extent existing financial economics theory makes valid predictions and therefore prove them, as well as attempt to discover new principles on which such theory can be extended and be applied to future financial decisions. Research may proceed by conducting trading simulations or by establishing and studying the behavior of people in artificial, competitive, market-like settings.

'' of investors or managers affects financial decisions and markets and is relevant when making a decision that can impact either negatively or positively on one of their areas. With more in-depth research into behavioral finance, it is possible to bridge what actually happens in financial markets with analysis based on financial theory. Behavioral finance has grown over the last few decades to become an integral aspect of finance. Behavioral finance includes such topics as: # Empirical studies that demonstrate significant deviations from classical theories; # Models of how psychology affects and impacts trading and prices; # Forecasting based on these methods; # Studies of experimental asset markets and the use of models to forecast experiments. A strand of behavioral finance has been dubbed quantitative behavioral finance, which uses mathematical and statistical methodology to understand behavioral biases in conjunction with valuation.


Quantum finance

Quantum finance is an interdisciplinary research field, applying theories and methods developed by quantum physicists and economists in order to solve problems in finance. It is a branch of econophysics. Finance theory is heavily based on financial instrument pricing such as stock option pricing. Many of the problems facing the finance community have no known analytical solution. As a result, numerical methods and computer simulations for solving these problems have proliferated. This research area is known as computational finance. Many computational finance problems have a high degree of computational complexity and are slow to converge to a solution on classical computers. In particular, when it comes to option pricing, there is additional complexity resulting from the need to respond to quickly changing markets. For example, in order to take advantage of inaccurately priced stock options, the computation must complete before the next change in the almost continuously changing stock market. As a result, the finance community is always looking for ways to overcome the resulting performance issues that arise when pricing options. This has led to research that applies alternative computing techniques to finance. Most commonly used quantum financial models are quantum continuous model, quantum binomial model, multi-step quantum binomial model etc.


History of finance

The origin of finance can be traced to the start of civilization. The earliest historical evidence of finance is dated to around 3000 BC. Banking originated in the Babylonian empire, where temples and palaces were used as safe places for the storage of valuables. Initially, the only valuable that could be deposited was grain, but cattle and precious materials were eventually included. During the same period, the Sumerian city of
Uruk Uruk, also known as Warka or Warkah, was an ancient city of Sumer (and later of Babylonia) situated east of the present bed of the Euphrates River on the dried-up ancient channel of the Euphrates east of modern Samawah, Al-Muthannā, Iraq.H ...

supported trade by lending as well as the use of interest. In Sumerian, "interest" was ''mas'', which translates to "calf". In Greece and Egypt, the words used for interest, ''tokos'' and ''ms'' respectively, meant "to give birth". In these cultures, interest indicated a valuable increase, and seemed to consider it from the lender's point of view. The Code of Hammurabi (1792-1750 BC) included laws governing banking operations. The Babylonians were accustomed to charging interest at the rate of 20 percent per annum. Jews were not allowed to take interest from other Jews, but they were allowed to take interest from Gentiles, who had at that time no law forbidding them from practicing usury. As Gentiles took interest from Jews, the Torah considered it equitable that Jews should take interest from Gentiles. In Hebrew, interest is ''neshek''. By 1200 BC,

The use of coins as a means of representing money began in the years between 600 and 570 BCE. Cities under the Greek empire, such as Aegina (595 BCE), Athens (575 BCE), and Corinth (570 BCE), started to mint their own coins. In the
