Aggregate Demand: Definition, Formula, Components

Feb 07, 2020Aggregate demand is the demand for all goods and services in an economy. The law of demand says people will buy more when prices fall. The demand curve measures the quantity demanded at each price. The five components of aggregate demand are consumer spending, business spending, government spending, and exports minus imports.

An aggregate demand curve is the sum of individual demand curves for different sectors of the economy.

An aggregate demand curve is the sum of individual demand curves for different sectors of the economy. The aggregate demand is usually described as a linear sum of four separable demand sources: $${\displaystyle AD=C+I+G+(X-M)}$$where • $${\displaystyle C}$$ is consumption (may also be known as consumer spending), which is given by $${\displaystyle C_{0}+c(Y-T)}$$ where $${\displaystyle Y}$$ is consumers' income and $${\displaystyle T}$$ the taxes paid by consumers,• $${\displaystyle I}$$ is investment,• $${\displaystyle G}$$ is government spending,• $${\displaystyle NX=X-M}$$ is net exports, where These four major parts, which can be stated in either 'nominal' or 'real' terms, are: • personal consumption expenditures ($${\displaystyle C}$$) or "consumption", demand by households and unattached individuals; its determination is described by the consumption function. A basic conception is that it is the total consumption expenditures of the domestic economy. The consumption function is $${\displaystyle C=C_{0}+c\times (Y-T)}$$, where • gross private domestic investment ($${\displaystyle I}$$), such as spending by business firms on factory construction. This is conceived as all private sector spending aimed at the production of some future consumable.

Adding these demand functions together into a single equation is tricky because each consumer has a different maximum willingness to pay (or value where the demand curve intersects the Y axis). The best way to do it is to have two separate functions, one that is true when the price is between 8 and 10, and the other where the price is lower than 8.
