First, give the simple equation for how much a change in autonomous government spending changes Ye. Second, we expect that the fall in G will lead to a fall in Ye that is even greater in dollars than the change in G and this will be due to the multiplier effect. Please explain how this multiplier effect (not the multiplier itself but rather the process through which the multiplier works) where a rise in G of $100 billion leads to a change in Ye of more than $100 billion. Once done, answer the following: if the size of the MPS rises as people become more concerned about the possible coming recession what will happen to the amount by which Ye changes with a given rise in G? Explain in words why this change makes sense.
