equilibrium conditions- where money supply equals money demand
- money supply generally given as a constant (vertical line)
- doesn't change w/ interest rate
- Ms = Md
- Md / $Y = L(i)
- Md / $Y - ratio of money demand to nominal income (fraction of total income that ppl hold as money)
- LM relation - equilibrium at intersection of money supply and money demand (downward sloping curve dependent on interest rate i from L(i))
- interest at level that that cause ppl to hold Md equal to Ms
- if Md=Ms then Bd=Bs since (wealth = B+D and wealth stays constant)
- changes in $Y >> shift of Md curve
- changes in interest rate >> mov't along curve
- money supply (not dependent on interest rate at all)
- money demand
- equilibrium
- higher $Y >> higher interest rate
- lower $Y >> lower interest rate
- money demand always equals money supply at equilibrium, so interest rate adjusts
- need higher interest rate w/ higher income to compel consumers to invest and have the same money demand as before, etc
