In: Economics
Define for each scenario whether AD (Aggregate Demand) or AS (Aggregate Supply) will shift, and indicate if it will be an outward shift (rightward) or inward shift (leftward).
a. A fall in the price of oil
b. A rise in consumer optimism
c. A hurricane destroys factories in South Carolina
d. Foreigners watch fewer U.S.-made movies
e. New inventions occur at a faster pace
f. A faster money growth
a. A fall in the price of oil reduces cost of production. This raises production and causes a rightward shift of the aggregate supply curve.
b. A rise in consumer optimism raises consumption which is a significant part of aggregate demand. This causes a rightward shift of the aggregate demand curve.
c. A hurricane destroys factories in South Carolina. This will increase the cost of production. This reduces production and causes a leftward shift of the aggregate supply curve.
d. Foreigners watch fewer U.S.-made movies. This implies lower export services and so lower net exports. This causes a leftward shift of the aggregate demand curve.
e. New inventions occur at a faster pace. This increases productivity and raises production of goods and services. This causes a rightward shift of the aggregate supply curve.
f. A faster money growth increases money supply and reduces rate of interest. This raises investment which is a significant part of aggregate demand. This causes a rightward shift of the aggregate demand curve.
