M: The standard abbreviation for imports produced by the domestic economy and purchased by the foreign sector, especially when used in the study of macroeconomics. This abbreviation is most often seen in the aggregate expenditure equation, AE = C + I + G + (X - M), where C, I, G, and (X - M) represent expenditures by the four macroeconomic sectors, household, business, government, and foreign. The United States, for example, buys a lot of the stuff produced within the boundaries of other countries, including bananas, coffee, cars, chocolate, computers, and, well, a lot of other products. Imports, together with exports, are the essence of foreign trade--goods and services that are traded among the citizens of different nations. Imports and exports are frequently combined into a single term, net exports (exports minus imports).

INCOME ELASTICITY OF DEMAND The relative response of a change in demand to a change in income. More specifically the income elasticity of demand is the percentage change in demand due to a percentage change in buyers' income. This notion of elasticity captures the buyers' income demand determinant. Three other notable elasticities are the price elasticity of demand, the price elasticity of supply, and the cross elasticity of demand.

[What's This?]
Today, you are likely to spend a great deal of time wandering around the downtown area hoping to buy either a wall poster commemorating last Friday (you know why) or a country wreathe. Be on the lookout for defective microphones.
