Measuring Money
How much money do we need?
The quantity of money (money supply) depends on the value of goods and services that will be bought …
= P x Q
02:16 28
Measuring Money
and on the velocity of money circulation = the number of transactions, served by the same money asset (V)
02:16 29
example I buy from George coffee with a €2 coin George buys from Maria a newspaper with the
same €2 coin Maria buys from Sofia a sandwich with the
same €2 euro coin One and the same €2 coin serves 3
transactions Therefore, for these transactions we do not
need €6 but only €2 The velocity of circulation (V) is 3 The greater the velocity, the smaller the
quantity of money needed.
02:16 30
The quantity of money
M = (P x Q) : Vor
MV = PQ
02:16 31
Measuring Money
Money aggregates amount of cash (coins and
banknotes)BUT other forms of money too (quasi
- money
02:16 32
M1 (high power money)
= currency in circulation (cash)+ demand deposits + checkable deposits+ traveler’s checks
02:16 33
M2
= M1+ savings deposits+ small time deposits
02:16 34
Comparing measures
get larger M1 < M2
add less liquid assets to larger measures
02:16 35
Which measure is best?
move together in general BUT behavior can vary in short-
term M2 most watched
02:16 36
Money Demand
Money demand – the quantity of liquidity that the public would like to hold at every level of the interest rate, ceteris paribus
02:16 37
Motives for money demand
Transactionaryto pay purchases
02:16 38
Precautionarybecause of the possible lack of synchronization of payments
02:16 39
Speculative (liquidity preference) because holding money has an opportunity
cost money has time value – it may bring interest on the one hand, people are motivated to have
liquidity, on the other hand, they want extra income
(interest) … when the interest rates fall, people will be
willing to convert part of their interest bearing assets into liquidity
… when the interest rates increase, the liquidity preference diminishes.
