Use the IS-LM model to answer this question. Suppose there is a simultaneous increase in government spending and increase in the money supply. First, define the policy mix.

Finally, explain the effects of the policy mix on investment. Do you suggest that a government should use that policy mix in order to increase investment? If not, which policy/policy mix would you suggest
