Need help answering question number 3 and 4. The data needed are from the other screenshots I included. Also for change in Y and change in interest rate, the change in Y is a decrease of 95.675 billion dollars and the change in interest rate is a decrease of 1.3823. Other relevant data are all included in the pictures below.

3. In the model, we are going to assume that the decrease in RGDP comes from a reduction in co and g. Intuitively, rms and consumers decreased their purchases due to the lockdown. From the solution of the model (the equation for output), compute the change in output when only on, be and 2' change. Finally, using that expression solve for AGO + Abe when AY is the value found in the rst point of this section and Ai the value in the second one. 4. Using your answer for Part1 Q4, provide a numeric answer for the following question. How much does Government Expenditures have to increase in order to make output recover from the crisis? Hint: You need to nd have a positive AG in order to have AY = 0 when co, bu and 'i change according to the previous questions. . Solve for the equilibrium GDP. . Solve for Consumption, Investment, Taxes, Government Expenditures, Net Exports and interest rate. . How much does GDP fall if autonomous consumption and investment fall at the same time (A00, Abe
