To understand the meaning
and mother nature of mixture demand.
To derive/sketch an aggregate
demand curve intuitively.
To understand the determinants
of the aggregate demand curve.
Aggregate demand (AD) is the
total level of costs on
services and goods in an economic climate
by people, firms, government
and the overseas sector.
AD = C + We + G + By - M
Imagine the general cost
level declines, ceteris paribus.
THREE things will happen…

If the standard price level falls…
• Lower prices provide households better liquidity
(consumers will have more cash to spend).
• Less cash will need to be borrowed.
• Interest rates will show up, thus stimulating
greater usage and expense.

AD = C & I + G & X - M

General price level (P)
When Sumado a increases, ceteris
paribus, usage will
increase, hence the AD
shape shifts seite an seite to
the proper from 𝐴𝐷0 to 𝐴𝐷1.
National output (Y)
(2) Age framework of population
• The younger the population, the higher the
degrees of consumption, nevertheless not guaranteed.
• An aging human population tends to have lower
