1.   Hence the equilibrium quantity Q is socially inefficient.

2.   The effect upon equilibrium quantity is again indeterminate, depending upon the relative size of the changes in supply and demand.

3.   The equilibrium quantity remains the socially efficient quantity.

4.   This means that equilibrium quantity will increase by an amount greater than that which either change would have entailed in isolation.

5.   A shift in either Ms or L will lead to a new equilibrium quantity of money and rate of interest at the new intersection of the curves.
