AD Models Flashcards
IS-LM model
Exogenous money supply
Money supply that is not dependant on the demand for money; vertical line
Endogenous money supply
Money supply that is dependant on the demand for money
Money demand curve
Depends on the Elasticity of liquidity preference
Under Keynesian belief, speculative money demand is higher responsive to changes in interest rates.
If individuals believe interest rates will increase, and thus the price of bonds fall, few individuals will want to buy the bonds now.
Instead they will hold money or near money, creating an elastic demand curve
The interest rate transmission mechanism
Increase money supply
Decrease interest rates
Increase investment, decrease savings
Increase injections, decrease withdrawals
Increase GDP
Increase prices
Problems with interest rate transmission mechanism
Elasticity of liquidity preference: Liquidity trap -Lower interest rates do not achieve economic growth from lower interest rates as money is held in idle balances, as it is believed that the central bank will have to increase rates
Unstable liquidity preference from changing expectations about the future level of interest rates
Elasticity of investment curve - Dependants on expectation and confidence not just interest rates
Exchange rate transmission mechanism
Increase money supply
Decrease interest rates
Decrease demand for money
Depreciation
Increase exports, decrease imports
Increase injections, decrease withdrawals
Permanent change in factor
Both curve shifts
