Answer:
When a financial friction is added to the short-run model it: shifts the MP curve up.
Step-by-step explanation:
The short-run model, IS/MP model, describes the Investment-Savings/Monetary Policy model used by the US Federal Reserve to decrease the real interest rate through the Federal Funds rate, i.
The Federal Funds rate is the interest rate that commercial banks with excess reserves lend to others in deficit. The resulting shift occasions a decrease in the real interest rate which triggers an increase in the inflation rate, and vice versa. With such short-run changes in the interest rate, inflation and output is influenced in desirable directions by the Federal Reserve as a foundation to achieve long-term shifts in the AD-AS model.
The AD-AS model is a long-term model that describes Aggregate Demand and Aggregate Supply which impact long-term inflation, interest rates, and output.
