Week 8 - Monetary policy & inflation Flashcards
3 functions of money
- A medium of exchange - it’s an accepted means of payment for the delivery of goods
- A unit of account - it describes the units in which prices are quoted and accounts are kept
- Store of value - It allowes future purchases
Measure money supply through monetrary aggregates (M’s)
- M0 is the narrowest definition covering notes & coins in circulation as well as notes & coins in bank vaults
- M3 is the broadest definition covering notes & coins in circulation, demand, time and saving deposits including OCD and large time deposits
- MB is the monetary base that the central bank can control
3 motives why people demand money
- Transactions motive
- Precautionary motive
- Speculative motive
Consumer real money balances formula
What is the relationship between consumer demand and real money balances? (3)
- Consumers demand money based on what it can buy
- If prices are rising then the value of the money in your wallet is falling
- If prices are falling then the value of money in your wallet is increasing
Define transactions demand motive
As real income (Y) increases people demand more money to make transactions
Define precautionary demand motive
Based upon psychology where money is demanded due to the possibility of unforeseen circumstances
Define speculative demand motive
This is based on interest rates (r), if they go up buy bonds and reduce your demand for money
What do the movements along and shifts on a demand for money graph show? (2)
- Movements along the curve show the speculative motive I.e as interest rates (r) increases the demand for money falls
- Shifts shows the transactions motive I.e as real income increases the demand for money, for a given interest rate increases
Supply of money - role of the central bank (5)
- The supply base money in the economy is determined by the central bank
- The money supply curve is therefore perfectly inelastic
- In order to expand or contract the money supply the central bank implements an open market operation
- This means buying of selling governments bonds in the actual money markets
- Only the central bank has the power to print money
Equilibrium in the money market (4)
- Equilibrium is where MS = MD which is the demand for real money balances = the supply of real balances
- MS is perfectly inelastic and fixed by the central bank
- In the short run money demand will be quite stable and is that continues the central bank can decide the rate of interest
- Once the interest is decided then all other interest rates in the economy adjust with it
How can the central bank reduce interest rates?
- Performs an open market operation by printing money electronically and buying government bonds
- This increases the supply of money in the economy so MS shifts from MS1 to MS2
- The reduction in the interest rates increases the speculative demand for money so there is a greater amount of liquidity in the system (L1 to L2)
Define inflation
Is the percentage increase in prices over a defined period of time and is always positive
Define deflation
- Is the percentage decrease in prices over a period of time
- It’s always negative but doesn’t occur often
Define disinflation
Is a situation where prices are increasing at a decreasing rate
