- 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 FalseStill with the same data on Macroland, a closed economy with no government sector, and with fixed price level and interest rate. Fill-in the blank in the following table, then answer the following question. GDP Yd C Iplanned Гипplanned 20 22 30 50 30 80 30 100 70 30 The Macroland's government reduced its taxes by 20, the income-expenditure equilibrium is expected to be: O 50 80 100 150CThe following equations describe an economy C = 100 + 0.75 Y. I = 50 – 25i where C' is aggregate consumption , Y is disposable income, I is aggre gate investment, Tis taxes, G is go vernment purchases and i is the int erest rate. Derive the IS curve for th T= G= 50 e economy.
- Inventories typically increase starting at the beginningof recessions, and begin to decline near the end ofrecessions. What does this say about the relationshipbetween planned spending and aggregate output overthe business cycle?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.13. а The accompanying table shows gross domestic product (GDP), disposable income (YD), con- sumer spending (C), and planned investment spending (Iplanned) in an economy.
