Changes in aggregate demand are represented by shifts of the aggregate demand curve. An illustration of the two ways in which the aggregate demand curve can shift is provided in Figure . A shift to the right of the aggregate demand curve. from AD 1 to AD 2, means that at the same price levels the quantity demanded of real GDP has increased.
