Ch 25 the monetary system Flashcards
three functions of money
medium of exchange
store of value(enables people to transfer purchasing power into the future)
measure of relative value, or unit of account
fiat money
legal tender under govt decree, not backed by physical commodity
growth rate of nominal gdp
inflation rate + growth rate of real gdp
quantity theory of money
in the long run, the ratio of money supply to nominal gdp is exactly constant
ex growth rate of money = growth rate of nominal gdp
ex growth rate of money supply = inflation rate + growth rate of real gdp
hyperinflation
country’s price level doubles in 3 years
consequences of inflation
wages do not change in sync with inflation
workers in contracts can lose out
mortgages and interest rates
social costs of inflation
- a high inflation rate creates logistical cost
- distorts relative prices
- sometimes leads to counterproductive policies like price controls
social benefits of inflation
- govt revenue is generated when the govt prints currency, called seignorage (benefit if the creation is low enough)
- can sometimes stimulate economic activity, ex if company has fixed wages, and inflation occurs, they now are able to higher more workers because the real wage of the original worker has fallen
dual mandate of central bank/ federal reserve bank/ fed
monitors financial institutions
- low and predicable levels of inflation
- maximum levels of employment
what does the fed do
audits financial statements
oversees interbank payments
holds reserves of private banks
allows fed to
1. influences short term interest rates
2. influences money supply and inflation rate
3. influence long term real interest rates
how does interest rate affect employment
lowering interest rates = more borrowinng = stimulates spending = demand curve to right
liquidity
needs funds to immediately conduct transactions
federal funds market/ federal interest rate
banks borrow and lend reserves to one another
interest rate in this market is the federal interest rate
shifts in demand curve for federal funds market
- economic expansion/ contraction
- changing liquidity needs, ex bank run
- changing deposit base, banks need to always have 10% of consumeres bank accounts in vault cash or in reserve
- changing reserve requirement from the fed
- changing interest rate paid by the fed for having reserves on deposit at the fed
federal funds market supply curve
vertical, does not respond to shifts, can be moved by the fed
