Interest Rate Determination
Here, you will learn about determining interest rates and how supply and demand play a role in determining interest rates. Pay attention to the Fed's role in this determination and to the effects of the increase of money supply on interest rates. What are the determinants of interest rates?
Money Market Equilibrium Stories
Learning Objective
- Learn the equilibrium stories in the money market that describe how the interest rate adjusts when it is not at its equilibrium value.
Any equilibrium in economics has an associated behavioral story to explain the forces that will move the endogenous variable to the equilibrium value. In the money market model, the endogenous variable is the interest rate. This is the variable that will change to achieve the equilibrium. Variables that do not change in the adjustment to the equilibrium are the exogenous variables. In this model, the exogenous variables are P$, Y$, and M$S. Changes in the exogenous variables are necessary to cause an adjustment to a new equilibrium. However, in telling an equilibrium story, it is typical to simply assume that the endogenous variable is not at the equilibrium (for some unstated reason) and then to explain how and why the variable will adjust to the equilibrium value.
