- Explain how to derive a total expenditures (TE) curve.Consider an economy where the various components of expenditure follow these equations: C = 10 + 0.8Ya I = 500 %3D G = 100 X = 300 M = 0.1Y T = 0.1Y A) Calculate the equilibrium level of GDP in this economy, highlighting what are the values of the Keynesian multiplier and the autonomous components of expenditure. Now assume that aggregate investment is also sensitive to movements of the interest rate: I = 500 – 2,000r %3D The money supply is equal to 1,000 and money demand satisfies the following equation: Ma = 2Y – 8,000r B) Solve for the equilibrium levels of output and the interest rate. Explain why the equilibrium level of output is lower than the one obtained in (a). C) Suppose that the government increases the tax rate to 0.15. Calculate the equilibrium effects of this policy and provide an explanation with the help of appropriate diagrams. D) Now assume that the price level can adjust. Using appropriate diagrams, explain the short- run impact of the policy introduced in (v) on…An economy is described by the following equations: C = 1,800+ 0.6 (Y - T) IP = 900 G = 1,500 NX = 100 PAE= T = 1,500 y* = 9,000 a. Find a numerical equation linking planned aggregate expenditure to output. Instructions: Round the value for mpc to one decimal place. Y b. Find autonomous expenditure and induced expenditure in this economy. Instructions: Round the value for mpc to one decimal place. Autonomous expenditure: Induced expenditure:
- Consider an economy where the aggregate planned expenditure (AE) components are given by: Consumption (C) = 1000 + 0.8Y Investment (I) = 200 Government Expenditure (G) = 250 Exports (Ex) = 400 Imports (Im) = 200 + 0.133Y Write the AE equation (simplified). Identify the autonomous component and the induced component. Graph the AE curve. Find and identify on the graph the equilibrium expenditure. Show on your graph the effect of an increase of 60 in government expenditure and find the new equilibrium expenditure. Find the expenditure multiplier.a) About Country A, what is your estimate of the country's marginal propensity to consume (MPC) based on the following information on its GDP (Y) and the components thereof (in billion dollars) for two past years? Show calculation. Year 1 Year 2 c) GDP C I 11200 8000 2200 12000 8500 2400 G 800 880 The next few parts are about Country B, whose government plans to cut taxes by $24 billion as a measure to fight the current recession. The marginal propensity to consume (MPC) in Country B is known to be 34. There will be no crowding-out effect. e) NX 200 220 b) What is the initial effect (in billion dollars) of the tax cut on Country B's aggregate demand? (The "initial effect" here refers to the effect on AD after only the first round of increased spending.) What is the total effect of the tax cut on aggregate demand? Explain why it is different from the initial effect. d) How does the total effect of this $24 billion tax cut compare to the total effect of a $24 billion increase in…Expenditure, E EA E E E₁ Y₁ Y₂ Y₁₂ Actual Expenditure Planned Expenditure Income, Output, Y 5.

- Answer the following questions, which relate to the aggregate expenditures model: Instructions: Enter your answer as a whole number. a. If Ca is $130, lg is $60, X, is -$10, and G is $40, what is the economy's equilibrium GDP? $ b. If real GDP in an economy is currently $250, Ca is $130, l is $60, Xn is –$10, and G is $40, will the economy's real GDP rise, fall, or stay the same? |(Click to select) c. Suppose that full-employment (and full-capacity) output in an economy is $250. If Ca is $180, Ig is $60, Xn is -$10, and Gis $40, what will be the macroeconomic result? O There will be an inflationary expenditure gap and employment levels will be above the full-employment level. O There will be an inflationary expenditure gap and employment levels will be below the full-employment level.THE AGGREGATE EXPENDITURE MODEL (IN THE SHORT RUN)YOU MUST SHOW YOUR CALCULATIONS IN THE SPACE BELOWFOR THE NEXT PROBLEM USE THE FOLLOWING FORMULA:CHANGE IN GDP = [ 1 / (1-MPC) ] * CHANGE IN GInitially, the economy is producing $13 trillion in goods and services and the government is spending $2 trillion.Then the government decides to increase its spending to $2.7 trillion. Compute the new equilibrium level of output. Assume that the marginal propensity to consume is 0.7 (MPC=0.7).Assume you have the following model of the expenditure sector:AD = C + I + G + NX C = Co + cYD YD = Y - TA + TR TA = TAo TR = TRo I = Io G = Go NX = NXo a. If a change in income by ∆Y = - 800 leads to a change in savings by ∆S = - 160, what is the size of the expenditure multiplier? c. If a change in exports by NX = - 200 is accompanied by a change in consumption by ∆C = - 800, what is the size of the expenditure multiplier?
