Explain how the shortrun values of (r, 1') are determined before the vaccine news shock. 2. Which, if any, of the graphs from Appendix C best depicts the change in the Keynesian cross due to the vaccine news shock? Explain. 3. Which, if any, of the graphs from Appendix A best depicts the shortrun change in the interest rate{s) due to the vaccine news shock? Explain. 4. Which, if any, of the graphs from Appendix B best depicts the shortrun change in output and price due to the vaccine news shock? Explain. 5. What are the effects of the shock on the short-run equilibrium values of output Y, consumption 0, investment I, real interest rate r and price P? Do not give any numerical answers, just ll in the following table with +, or 0 to indicate whether each variable increases (+), decreases (}, or doesn't change (0}. There are 6 blanks to ll.
