Use the following data to work Problems 1 to 4:

The following events have occurred in the history of the United States:

• A deep recession hits the world economy.
• The world oil price rises sharply.
• U.S. businesses expect future profits to fall.

Explain for each event whether it changes short-run aggregate supply, long-run aggregate supply, aggregate demand, or some combination of them.

Answer 1

a) A deep recession in the economy- It s a situation when there is decrease in income , output and employment . Therefore aggregate supply decrease and shift backwards. At the same time due to recession , people lost their belief in government and consume less goods and services . Due to that aggregate demand falls. Due to fall in aggregate demand and supply equilibrium price remain the same but real GDP falls.

B) Increase in world oil prices. Due to increase in oil prices , consumption of oil will decrease and aggregate demand for oil will reduce . Therefore, aggregate demand curve will shift backwards. Due to that, equilibrium price will fall and real GDP will also reduce. It has negative imppact on the economic growth of US.

C) US business expect future profit to fall- When the producers of US feel that they will have less profit in future they reduce the production level and due to that aggregate supply falls. With reduction in aggregate supply , price level will increase in US and real GDP will fall.
