Question

Use the IS-LM model to answer this question. Suppose there is a simultaneous increase in taxes and reduction in the money supply. Explain what effect this particular policy mix will have on output and the interest rate. Based on your analysis, do we know with certainty what effect this policy mix will have on investment? Explain.

Answer: In this case, the LM curve shifts up and the IS curve shifts to the left. In this case, output will clearly fall. What happens to the interest rate depends on the relative magnitude of the two policies. The effects on I are again ambiguous.
