21
Q

What is money demand?

A

amount of wealth households choose to hold as money

22
Q

When do people want to hold more money?

If ir above eqm level,

Excess supply of money (people would rather hold less money)

Excess demand for bonds(people would rather hold more bonds)

With excess demand for bond, bond price will increase in bond market. As bond price increase, interest rate decrease until people are satisfied with holding qty of money

25
Q

In keynesian model, _____ if Y rises, money demand _________

other things equal
rises and shift right

(cause there is excess demand, bond prices fall)

26
Q

This causes Ip and a to decrease, AE decrease, Y star decrease

Money demand decrease again

monetary policy: faster to enact and easier to reverse

29
Q

How does monetary policy accomodate fiscal policy?

A

An expansionary fiscal policy leads to a rise in the interest rate –> the resultant crowding out reduces the policy impact

If Central Bank wants to accommodate the expansionary fiscal policy, it can eliminate crowding out by preventing the interest rate from rising

30
Q

What does the fed do to target short term interest rate?

A

targets the Fed Funds Rate (FFR) = rate at which banks lend reserves to one another overnight, act as benchmark for other interest rate

Other assets pay higher rates, due to being longer-term and higher risk, thus earning term premiums and risk premiums.
Difference (spread) between these rates and the FFR is usually stable

31
Q

What is the relationship between IOR, Fed Funds Rate and Discount rate?

How to get banks to reduce reserves

A

By manipulating ceiling (discount rate), and floor( IOR) , Fed can control ffr

FFR: Interest rate in the interbank market for reserves. Fed use open market operations to affect the interbank rate

IOR: Ir paid on reserves. Banks will not lend reserves to other banks if IOR > interbank rate Thus, IOR is the floor for the FFR

Discount rate:Interest rate charged by central bank for lending reserves. Banks will not borrow reserves from other banks if discount rate < interbank rate. Thus, discount rate is the ceiling for the FFR
