MPC (Marginal Propensity to Consume) means extra consumption from an extra dollar of income.
And, MPS (Marginal Propensity to Save) means extra saving from an extra dollar of income.
MPC and MPS describe consumer's tendencies to fully utilize their income. MPC relates to consumption tendency while MPS to saving tendency.

3. Patsy Prune had a question on an assignment which stated the following:
"Suppose the Federal Reserve decided to reduce the interest rates or the Fed Funds rate. Demonstrate what will happen to the price level and the level of output using the AS/AD framework."
Patsy wrote the following in her answer: The AD will shift to the right causing an increase in the price and the level of output in the short-run. At the same time the AS will shift to the left because of higher prices. Output will increase and the price level increase as well in the long-run. So in the long-run both output and price will increase.
Is Patsy correct in her reasoning? Explain and be sure to use a graph to explain your answer.View Full Posting Details
