LIBR The Aggregate Expenditure or Keynesian macroeconomics model is based upon the theory that the level of GDP in the economy is determined by the level of aggregate spending. True False
Quèstion 1 In an open mixed economy, the inflationary expenditure gap may be described as the O A. excess of Sa + M+T over lg + X+ G at the full-employment GDP. O B. excess of GDP over Ca + lg +Xn + G at the full-employment output. OC excess of Ca + Ig + Xn + G at the full-employment GDP. O D. extra consumption that occurs when investment increases in a full-employment economy.
QUESTION 6 Potential GDP Aggregate expenditure AE, 45° Y. Real GDP (Y) When real GDP is greater than Yo in the diagram above: O A. - inventories will decrease OB. ·Aggregate expenditure will be less than Real GDP OC. Aggregate expenditure will be equal to Real GDP OD. O D. inventories will increase QUESTION 7 Y G Xn $1,000 $1,400 1,400 1,400 1,400 1,400 $0 $800 -$200 2,500 5,000 7,500 10,000 2,300 3,800 5,300 6,800 1,000 1,000 1,000 1,000 -200 -200 -200 -200 Suppose you are given the data in the table above for a hypothetical economy. All data are in billions of dollars. Yis actual real GDP, and C, Ip, G, and Xn are the consumption, planned investment, government purchases, and net exports components of aggregate expenditures, respectively. Calculate the equilibrium GDP (give your answer in billions of $) Aggregate Expenditure
9. Suppose Dina calculates her permanent income by adaptive expectations. Year 2010 Dina's permanent income was 68,000, and year2011 actual income is 71,000. Assume that, long-run marginal to consume is 0.90 and short-run marginal propensity to consume is 0.18. What is her consumption expenditure year 2011? * O 51,740 O 41,740 O 59,500 O 44,750 none of the above is correct
COURSE: MACROECONOMICS - IS-LM and/or MUNDELL FLEMING MODELS Refer to 2 different models (and/or conditions) under which an increase in the amount of money circulating in the economy has a NULL impact on GDP. Then, refer to 2 different models (and/or conditions) under which an increase in the amount of money circulating in the economy has a MAXIMUM impact on GDP. EXPLAIN very briefly the mechanism by which each model generates that NULL or MAXIMUM impact on GDP. Hint: 2 conditions under increase of M (money) and how impact null (zero) and maximum on GDP. Example, considering both fiscal or monetary policies or liquidity trap model. Please graph and explain on detail both cases.
What could cause the following shift? O Increase in GDP. O Expansionary fiscal policy. O Decrease in future MPK. All of the above. FE IS LM
2. Consider a Keynesian IS-LM model for national income: Y = C(Y-T) + I (r) + G L(r,Y)= M³ IS: LM: where we consider Y and r as the endogenous variables and G, M³, and T as the exogenous variables. (a) Find the effect of a lump-sum tax, T, change on Y, i.e., OY/OT, using the implicit function theorem.
In the Aggregate Expenditure framework, which of the following government policy choices offer a possible solution to inflationary pressures? (Check all that apply.) Select all that apply: a. A reduction in taxes for businesses that increase investment. Ob. A major decrease in what the government spends on healthcare. O c. A decrease in military spending. O d. A tax increase on consumer income.
4. An economy's Planned Aggregate Expenditure (PAE) is given by the formula PAE = 3,400 +0.6Y in terms of its autonomous and induced components respectively, where Y represents output. a. State what is meant by the terms autonomous and induced expenditure b. Given that, under Keynes, the economy is in short term equilibrium where Y-PAE, find the numerical level of short-run output using the above equation. c. If potential output in the same economy is 9,000 draw a Keynesian Cross diagram and label any gap which exists between actual and potential output.
line shows the relationship between planned aggregate expenditure and output, and line represents the condition that planned aggregate expenditure and output are equal. In the Keynesian cross diagram, the the expenditure; 45-degree O45-degree; consumption function 45 degree; expenditure consumption function; 45-degree
