New equilibrium = S0 Aggregate expenditures
Given an economy is currently producing at $1.47 GDP, natural rGDP is $1.67, and the MPC is 0.94, then the multiplier for increases in aggregate expenditures is: A (round to ane decimal point). This means the federal government should increase its expenditures by A (whole number) billion dollars.
Planned AE (PAE, trillion $) 45° AE = Y PAE₂= 7+0.5Y PAE = 5 +0.5Y PAE = 3 +0.5Y Actual AE (GDP, Y, trillion $) Refer to a graph above. Suppose the the economy has the planned aggregate expenditure of PAE2 and the potential GDP is $10 trillion. Which of the following statements about this economy is false? O There is an inflationary output gap of $4 trillion. O In order for this economy to get back to the potential GDP, the PAE curve needs to shift to the right The economy is in an expansion. O The economy produces more than spends.
stlon 16 Troll Island is a small island nation that recently experienced an autonomous change in aggregate expenditures (AE). AE increased by 2 billion, and the marginal propensity to consume on Troll Island is equal to 0.6. What is the change in Troll Island's real GDP after the increase in AE? Enter your answer in billions of dollars, rounded to one place after the decimal. For example, an answer of $2,500,000 should be entered as 2.5. %24 billion

25. Which one of the following statements is INCORRECT? A The level of autonomous consumption is determined by the non-income determinants of consumption spending. The impact of a change in one or more of the non-income determinants of consumption can be illustrated by a shift В of the consumption function. The level of autonomous consumption determines the position of the consumption function. Investment spending is the most stable component of aggregate spending in the C economy.
