The total money value of all the finished goods and services produced in an economy in one year. It includes all consumer and government consumption, government spending and borrowing, investments and exports (minus imports) and is taken as a guide to a nation’s economic health and financial well being. However, some economists feel GDP is inaccurate because it fails to measure the changes in a nation's standard of living, unpaid labour, savings and inflationary price changes (such as housing booms and stockmarket increases).
The term is interchangeable with stock exchange, and is a market that deals in securities where market forces determine the price of securities traded. Stockmarket can refer to a specific exchange in a specific country (such as the London Stock Exchange) or the combined global stockmarkets as a single entity. The first stockmarket was established in Amsterdam in 1602 and the first British stock exchange was founded in 1698.
