An economy (from Greek οίκος – "household" and νέμoμαι – "manage") is an area of the production, distribution, or trade, and consumption of goods and services by different agents. Understood in its broadest sense, 'The economy is defined as a social domain that emphasizes the practices, discourses, and material expressions associated with the production, use, and management of resources'. Economic agents can be individuals, businesses, organizations, or governments. Economic transactions occur when two parties agree to the value or price of the transacted good or service, commonly expressed in a certain currency. However, monetary transactions only account for a small part of the economic domain.
Finance is a field that deals with the study of investments. It includes the dynamics of assets and liabilities over time under conditions of different degrees of uncertainties and risks. Finance can also be defined as the science of money management. Market participants aim to price assets based on their risk level, fundamental value, and their expected rate of return. Finance can be broken into three sub-categories: public finance, corporate finance and personal finance.
The best scheme of finance is, to spend as little as possible; and the best tax is always the lightest.
Jean-Baptiste Say A Treatise On Political Economy (Fourth Edition) (1832) Book III, On Consumption, Chapter VIII, Section I, p. 449
Nothing in finance is more fatuous and harmful, in our opinion, than the firmly established attitude of common stock investors regarding questions of corporate management. That attitude is summed up in the phrase: "If you don't like the management, sell your stock." [...] The public owners seem to have abdicated all claim to control over the paid superintendents of their property.
