Consider the following model of the goods market in a closed economy, where 5 measures the extent of the spread of covid-19 within the country: Z=C+I+G C: 5+(0.753)YD I=2.523 G=2.5+s YD=YT T=1+0.25YTR Y=Z (1) Planned aggregate expenditure Consumption function Planned investment Government expenditure Disposable income Net Tax function Equilibrium Condition QUESTION 3 Using the model in Question 1 and rounding to 4 decimal places, solve for the equilibrium value of the government expenditure multiplier when: The economy is affected by oovid-19 with s = 0.2, but there are no transfers TR = O. QUESTION 4 Using the model in Question 1 and rounding to 4 decimal places, solve for the equilibrium value of '1"it when: The economy is affected by oovid-iQ with s = 0.2, but there are no transfers TR = 0
