An economy is an area of the production, distribution or trade and consumption of goods and services by different agents in a given geographical location in various countries. Economic agents can be individuals, businesses, organizations, or governments. Economic activity is spurred by production which uses natural resources, labor and capital. The economic domain is a social domain of human practices and transactions. There are three types of economy: a market-based economy, where goods and services are produced and exchanged according to demand and supply, a command-based economy, where political agents directly control what is produced and how it is sold and distributed, and a green economy, where the growth income and employment are driven by public and private investments that reduce carbon emissions and pollution, enhance energy and resource efficiency, and prevent the loss of biodiversity and ecosystem services.
Finance is a broad term that describes two related activities: the study of how money is managed and the actual process of acquiring needed funds. Because individuals, businesses and government entities all need funding to operate, the field is often separated into three sub-categories: personal finance, corporate finance and public finance. These three categories are concerned with activities such as pursuing sound investments, obtaining low-cost credit, allocating funds for liabilities and banking.
