Formula for AD (based on curve)
Nominal (money) net output / average price level
Contraction of AD?
Rise in the price level leads to a fall in demand.
Extension of AD?
Fall in price level leads to an increase in demand.
When will AD shift right?
When any of the components of AD increase
When will AD shift left?
When any of the components of AD fall
