| Abstract from DBPedia | In microeconomics, supply and demand is an economic model of price determination in a market. It postulates that, holding all else equal, in a competitive market, the unit price for a particular good, or other traded item such as labor or liquid financial assets, will vary until it settles at a point where the quantity demanded (at the current price) will equal the quantity supplied (at the current price), resulting in an economic equilibrium for price and quantity transacted. It forms the theoretical basis of modern economics. In macroeconomics, as well, the aggregate demand-aggregate supply model has been used to depict how the quantity of total output and the aggregate price level may be determined in equilibrium.需要（じゅよう、英: demand）と供給（きょうきゅう、英: supply）すなわち、需要および供給の定義から説明すると、需要とは、個人や企業などの経済主体が、市場において交換・販売を目的として提供されている財やサービスを購入しようとする（消費）行為であり、供給とは経済主体が市場で交換・販売を目的とし自己の所有物を提供する（生産）行為である。「需要と供給」は合わせて短縮して需給（じゅきゅう）とも呼ばれる。 (Source: http://dbpedia.org/resource/Supply_and_demand) |
