Chapter 16 Flashcards
Inflation
An increase in the overall level of prices
Deflation
A fall in the overall level of prices
The inflation rate is the percentage change in the:
- CPI
- GDP deflator
- Other index of overall price level
Core Inflation
Excludes goods with historically volatile price changes
All-items inflation (headline inflation)
Includes all of the goods that the average consumer buys
What two ways can the economy’s overall pice level be viewed
- As the price of a basket of goods and services
2. As a measure of the value of money
Level of prices in the economy
The overall level of prices adjusts to the level at which demand for money equals the supply
What are the effects of momentary injection
- Short run- output and prices rise
- Workers want higher wage
- Long run- more money supply will lead to higher prices; output stays the same
Quantity theory of money
A theory asserting that the quantity of money available determines the price level and that the growth rate in the quantity of money available determines the inflation rate
What are real variables
Variables measured in physical units
What is classical dichotomy
The theoretical separation of nominal and real variables
What is monetary neutrality
The proposition that changes in the money supply do not affect real variables
What is the quantity equation
MV = PY
V: velocity of money
Y: Real GDP
P: Price level
M: quantity of money
What is the velocity of money
The number of times that the entire money supply turns over in a given period
What does the quantity equation imply
That increasing the money supply leads to inflation and decreasing the money supply leads to deflation
Leads to the conclusion that price level is immaterial
What are menu costs
The money, time, and opportunity costs of changing prices to keep up with inflation
What are shoe leather costs
The time, money, and effort costs of managing cash in the face of inflation
What is Tax distortion
The fact that tax laws only take into consideration nominal income, not what you can buy with it
What is the nominal interest rate
The reported interest rate that is not adjusted for the effects of inflation
What is the real interest rate
Adjusted for the effects of inflation
Equation for real interest rate
Real interest rate = Nominal interest rate - inflation rate
What is the aggregate price level
A measure of the average price level; in practice, the CPI or GDP price deflator
What are menu costs
The costs of changing prices to keep pace with inflation
What is disinflation
A period in which inflation rates are falling but still positive
