Assume that you live in a country that is a major importer of Russian oil. How will the Russian invasion of Ukraine and subsequent
international sanctions against Russian exports affect your nation.
a. What curve would shift first in an Aggregate Demand Aggregate Supply model for your country?
b. How would the aggregate price level and aggregate output level change in the short run?
What is this phenomenon called?
What effects would each of the following have on aggregate demand or aggregate supply? Justify your answer. In each case use a diagram to show the expected effects on the equilibrium price level and real output level in the economy. Assume that all other things remain constant and prices are inflexible downward.
(a) A reduction in interest rates at each price level
(b) A sizable increase in labor productivity.
(c) The nation’s currency appreciates against its major trading partners .
Assume that the long-run aggregate supply
curve is vertical at Y= 3,000 while the short-run
aggregate supply curve is horizontal at P = 1.0.
The aggregate demand curve is Y = 2(MIP) and
M = 1,500.
▪a. Is the economy is initially in long-run
equilibrium?what are the values of P and Y?
▪b. If M increases to 2,000, what are the new
short-run values of P and Y?
▪c. Once the economy adjusts to long-run
equilibrium at M = 2,000, what are P and Y?
