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

Solutions

Expert Solution

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.

Aggregate Supply (AS) and Aggregate Demand (AD) model and AS/AD curves are essential to understand macroeconomic fluctuations (business cycles). Discuss the importance AS-AD model in explaining the macroeconomic conditions of the economy and business cycles like recessions. What factors shift AS and AD curves? How do you explain macroeconomic fluctuations using AS-AD model and AS/AD curves?

Consider the Aggregate Demand (AD)-Aggregate Supply (AS) model studied in class. The AD function is composed of the following elements: ? = ? + ??? ∙ (? − ?); ? = ? − ?; ? = ?; ?? = ?∗ − ?; ? = ? + ? ∙ ? The AS is given by the function: ? = 4, (a) Assume that the economy is in its very short-run equilibrium with the following values: ? = ? = 0; ?...

Determine whether each of the following would cause a shift of the aggregate demand curve, a shift of the aggregate supply curve, a shift in neither curve, or a shift in both curves. If a shift is caused, indicate which curve shifts, and in which direction it shifts. What happens to aggregate output and the price level in each case? 1] The price level changes. 2] Consumer confidence increases. 3] The supply of resources decreases. 4] The wage rate decreases.

#2 In the following table, indicate the effect of each scenario on the aggregate demand curve. Scenario Change in Aggregate Demand Government spending increases.(Increases or Decrease) The amount of taxes collected decreases. (Increases or Decreases) #4 Why does a reduction in taxes have a smaller multiplier effect than an increase in government spending of an equal amount? A tax cut directly injects zero new spending into the economy because the government has purchased no new goods and services. An increase...

1. Using the aggregate demand (AD), the short-run aggregate supply (SRAS), and the long-run aggregate supply (LRAS) curves, briefly explain how an open market purchase will affect the equilibrium price level (P) and real output (Y) in the short run. Assume the economy is initially in a recession. 2. Using the quantity equation (the equation of exchange) briefly explain the quantity theory of money. Specifically, how the quantity theory of money explains why inflation occurs.
