Term 2 week 7 and 8 Flashcards
What happens in short run if you decrease the money supply?
What is the relationship between money supply and interest rate?
GDP falls
Interest rate increases.
Liquidity effect
What are the potential reasons behind nominal rigidities?
Sticky wages
Long term contracts
Menu costs
Inattention
What is the bridge between the nominal and real economy?
Fisher equation
Due to nominal rigidities changes in the money supply can impact real interest rates.
What is the fisher equation?
What does it show?
Rt = it - pit+1 expected
real interest rate = nominal interest rate - expected inflation
Changes in the nominal interest rate are not matched by 1 for 1 changes in expected inflation so this causes variation in the real interest rate.
How can you graphically show, money demand, money supply and money demand
Why is it better to use interest rate as main tool for monetary policy?
Money demand shocks do not have a big impact.
What is the equation for equilibrium level of money?
M* = PY x K(i)
How do central banks choose what interest rate to check?
What is the taylor rule equation?
What values did taylor argue?
Taylor suggested that banks should choose based on:
distance from output target
Distance from inflation target.
The coefficients show how sensitive the centrla ban
What is the conclusion of moeney?
Neutral in long run
non-neutral in short run.
What is a shortcoming of the RBC model in terms of money?
RBC does not take into account the non-neutrality of money in the short run.
But monetary policy has a role to stabilise business cycles.
What is the key feature of New-Keynsian models?
Price-stickiness.
How is potential output dealt with in the Keynsian model?
What is output gap?
potential output is y bar and is exogenous to the model
The % deviation of output from potential output.
What is consumption in the Keynsian model?
Ct = (ac + act)YbarT
ac = constant share of output that goes to consumption
act = changing share of output that is caused by shocks.
What is government spending in keynsian model?
GS = (ag + agt)Ybart
a constant part of government spending and a one subject to shocks.
What is investment in the keynsian model?
it = ig + iat - b (Rt-r)Ybar
What is the Rt-R part of investment
