Chapter 16: Inflation Flashcards
What is inflation and deflation?
inflation: an increase in the overall price level, money becomes worthless
Deflation: a fall in the overall pricelevel: harmful for firms
Nominal vs real inflation rate
Real: prices before inflation
Nominal: prices added with inflation using GDP deflator
2 ways of measureing inflation
all items inflation: all G+S that the average person buys
Core inflation - volitile, energy and food
what is the classical theory of inflation?
when the value of money decreases, inflation happens.
money looses its store value
how is the value of money determined?
through money supply: BOC
through money demand: people wanting liquidity.
- depends on price levels.
- in the LR, price levels adjsut to the demand for money.
what is monetary injection?
when the BOC puts money into the economy making the dollar worth less.
Short run: prices increase and output increases.
Long run: workers want higher wages
higher prices, same output - causes inflation
What is the quantity theory of money used for?
how price levels are determined and how they change over time.
quantity of money available determines the price level.
growth rate of #money determines the inflation rate.
M x V = P x Y
Velosity is stable
What is monetary neutrality?
if you change quanity of money in the economy, it affects prices, but have no effect on output in the long run.
Neutrality: when prices go up, wages go up as well.
if money supply doubles, nominal GDP would double, but not Real GDP
- large economic changes are bad
predictable costs of inflation
- menu costs
- the costs associated with changing prices
- time money oppertunity - shoe-leather costs
- managing cash - tax distortion costs (bracket creep)
-this happens when tax laws only take into consideration nominal income - not what you can buy with that income
unpredictable costs of inflation
Nominal interest rate - inflation rate = real interest rate (adjusted for inflation)
changes in prices affect interest rates
what is Deflation?
A sustained fall in the price level
not good for production.
benefits the spender at the cost of the borrower
decrease in consumption and investment - loans are more expensive to pay back
Disinflation
inflation is falling but still positive
when the central bank trys to contain inflation through contracitonary monetary policy
shift left
Hyperinflation
extreme infltaion = high price levels
currency becomes valueless
How does inflation protect deflation?
through monetary policy: small changes are better than bigger ones
makes it easier for rism to adjust real wages, without affecting productivity by changing labour demand conditions
Monetary policy & inflation
it is hard to maintain stable prices and full employment
Potential output: total amount of output a country could produce if all of its resouces were fully Engaged. (no cyclical unemployment)
output gap = inflation
more output = less unemployment
less output = more unemployment
