1. Suppose the Council of Economic Advisors (CEA) hired you as an Economist (Economic consultant). The head of the council tells that she believes the current unemployment rate of 9% is too high. They would like to increase real aggregate output (RGDP). She wants to know what policy to pursue to increase RGDP by $2 trillion ($2,000 billion). The best estimate she gave you is the value of MPC = 0.8. Which of the following policies should you recommend and why? You need to show your work of estimations and explain in words.
a. Increase government expenditure (G) by $400 billion
b. Reduce taxes by $400 billion
c. Reduce taxes by $400 billion and increase govt. expenses by $200 billion
d. Increase G by $500 billion
2. Using the value of MPC = 0.8, and knowing the difference between the values of expenditure multiplier and the tax multiplier, it can be safely stated that the reduction of taxes by $400 billion (other things staying the same), Estimate increased level equilibrium aggregate output (RGDP). You need to show your work of estimations.
3. Suppose the Stimulus package (The American Recovery and Reinvestment ACT of 2009) for $862 (originally it amount was approved for $787 billion and subsequently increased to $862 billion) was allocated for spending in all 3 components of the AE model of Keynesian Macro model (RGDP = C+I+G); where they spent the bulk of it in G (government expenses for infrastructure), some of it in Tax rebates (-T), and the rest of it in the form of subsidies/credit in Private business investment (I). If the actual increase in RGDP was $2 trillion ($2,000 billion), assuming other things stay the same, estimate the actual or real world effective multiplier. Show you’re your work of estimations,
