1. Income - Expenditure Problem: {Modules 28 & 29) Below is the data for an income-expenditure model. Use the table below to answer the following questions. Assume that taxes, government purchases and net exports are all So. Remember that prices are fixed in the income-expenditure model, so we don't have to worry about them changing in this model. a. (2 pts.) Complete the table. Use the following formulas: ' AEptanned : C + [planned ' GDP : AEpmnned + J(unplm'lrwd 01' l(unplanned : GDP _ AEpianned 0 Also remember that MAENWM can bc a change in A or a change in Imam\".

(2 pts.) Find the MPC for this economy. Remember that A means change, and MPC = mmmmf'm\" .Also remember to find the change in consumption, calculate how much C Ain disposable than me changes from one row to the next. Use the same two rows to calculate the change in YD. Show your work for full credit. c. Find \"A\" and \"MPC\" and plug them in to write out the aggregate consumption function, C = A + MPC x YD. (Hint: You will leave C and YD in your equation as is, and you will find numbers for MPC and A. Remember that YD stands for disposable income and A is autonomous consumer spending. We can also sayr that A is the amount of consumption when YD = 0. (look in the first row of numbers. You've already found the MPC and you can find A in the table.) d. For the table in part a., what is the value of Y*, the \"income - expenditure equilibrium\" GDP? (The level of GDP when income equals spending. You should be able to see it in your completed table, and if you like algebra, you can solve it with algebra.) c. What is the value of the multiplier? The formula for the multiplier is: multiplier = (lMPCj (4 pts.) If planned investment spending increases BY $150 billion from what it was in part a., what will be the new Y*? (Note there is a difference between something \"increasing by\" and \"increasing to\".) Fill in the three empty columns in the table and then find Y'\".

Also verify your answer in part f. by using the formulas (AY = multiplier x MAEWWd) and (new Y\" : old Y* + AY) Old Y'\" was calculated in part d. Show your work for full credit. h. (4 pts.) Note that we have reset the Iplanned to 100 in the table below. Suppose autonomous consumer spending increases by $100 billion. Fill in column (2. (Hint: \"A\" increases from what you calculated in part c by $100 billion. Note that you'll have to calculate the rest of the numbers in column C), Based on what you see in the table, what do you think will be the new Y*?
