A country’s gross domestic product is a useful guide to the level of activity in its economy, and its growth rate can have a significant effect upon inflation and unemployment. That makes it a matter of importance to the study of macroeconomics, but its usefulness in other respects is more limited. It is concerned only with products that are bought and sold, so it takes no account of subsistence farming, domestic activity, voluntary work or crime. Also, since it takes account only of changes in value that are reflected in price, it tends to underestimate the value of technological improvements such as increases in computing power. It is thus an incomplete guide to a country’s prosperity - and it is even less useful as a guide to well-being because of its exclusion of such matters as the levels of health, education, and security.
Definitions
Gross domestic product (GDP) can be defined as "the total market value of all final goods and services produced within an economy in a given year" [1]. The word "gross" indicates that no deduction is made for the loss of value due to the depreciation of assets, and the word "domestic" indicates that net income from abroad is not included. (If income from abroad is allowed for, gross domestic product becomes gross national product (GNP), and if depreciation is allowed for, that becomes net national product or simply national income).
