Theoretically, a decline in G such as the one in the first question leads to a change in equilibrium Y, Y_e.First, give the simple equation for how much a change in autonomous government spending changes Y_e. Second, we expect that the fall in G will lead to a fall in Y_e 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 that shows how spending ripples down through the economy) where a rise in G of $100 billion leads to a change in Y_eof more than $100 billion.After 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 Y_e changes with a given rise in G? Explain in words why this change makes sense.
