11 Exhibit 3-1 PL P SRAS LRAS AD Y Y* GDPR Refer to Exhibit 3-1. The economy is currently producing at level Y. If an economist believes the economy (itself) can move to Y*, then he believes that the economy will likely stay "stuck" in short-run equilibrium. SRAS curve will shift rightward and intersect the AD curve. O AD curve will shift rightward and intersect the SRAS curve. LRAS curve will shift leftward until it intersects the SRAS and AD curves at Y.

Consider a keynesian macromodel Y=(C0+G+I) / (1-c) where C0 is autonomus consumption, G is government consumption expenditure, I is investment expenditure, c is the marginal propensity to consume. In this model, if lthere is an increse in both labor productivity and the marginal propensity to consume while autonomus expenditures remain unchanged, what will happen to the level of employment? a. can't say for sure b. decreses c. stays the same d. increases

Attempts Average / 2 5. The aggregate supply curve in the simple Keynesian model Complete the following statement to make it true. "In the AD-AS framework, the simple Keynesian model includes an aggregate supply curve that Natural Real GDP." until the economy reaches its slopes upward Under what condition will an increase in total spending lead to an equivalent increase in Real GD O When the economy is producing more than Natural Real GDP. O When the economy is producing at Natural Real GDP. O When the economy is producing less than Natural Real GDP. O When the aggregate supply curve is vertical. is horizontal is vertical

Suppose the economy is in short-run equilibrium above potential GDP and no policy is pursued. Using the static AD-AS model in the figure above, this would be depicted as a movement from U SRAS AD 3 AD₂ AD₁

Assume an economy operates in the intermediaterange of its aggregate supply curve. State thedirection of shift for the aggregate demandor aggregate supply curve for each of thefollowing changes in conditions. What is theeffect on the price level? On real GDP? Onemployment?a. The price of crude oil rises significantly.b. Spending on national defense doubles.c. The costs of imported goods increase.d. An improvement in technology raises laborproductivity.
