What can Inflation be measured by?
percentage change in the consumer price index
What do most economist today rely on to explain the long-run determinants of the price level and the inflation rate?
quantity theory of money
What happens to the number of dollars needed to buy a representative basket of goods, when the price level falls?
Decreases, so the value of money falls.
What way is the money supply curve when the value of money is on the vertical axis?
Vertical because we assume the central bank controls the money supply.
When does the supply of money increase?
Fed makes open-market purchases
What does money demand depend on?
the price level and the interest rate
What does the value of money do when price levels rise?
decreases, so people want to hold more of it
What does quantity of money do when price levels decrease? Money market is drawn with the value of money on the vertical axis.
What happens to the equilibrium value of money when money supply is increased? Money market is drawn with value of money on the vertical axis.
decreases, while the equilibrium quantity of money increases.

What is the quantity equation?
M x V = P xY
relates the quantity of money to the nominal value of output (nominal GDP)
What is the Fisher effect?
the one-for-one adjustment of the nominal interest rate to the inflation rate.
nominal interest rate = inflation rate + real interest rate
What is wealth?
refers to the total of all stores of value, including both money and nonmonetaty assets like stocks and bond.
determines how much of our wealth we allocate in the form of money versus other non-monetary assets in the classical model of inflation

a situation in which the market price (value of money) has reached the level at which the quantity (of money) demanded equals the quantity (of money) supplied
In what ways can the Government obtain funds?
taxes, issue bonds, Print money
why is the money supply curve vertical?
because the Fed has fixed the quantity of money available
What causes the money supply curve to shift?
Change in supply of money.
Why is the money demand curve downward sloping?
indicating that when the value of money is low (and the price level is high), people demand a larger quantity of it to buy goods and services.

What is the velocity of money?
The rate at which money changes hands
What is the formula for the velocity of money?
V = (P x Y)/M
What does the numerator in the velocity formula represent?
What is the quantity equation?
M x V = P x Y
A change in M in the quantity equation causes what to change?
A change in M causes nominal GDP & P to change by the same percentage.
Rapid money supply growth growth causes what?
If real GDP is constant, what is the relationship between the inflation rate and money growth rate?
Inflation rate equals money growth rate
If real GDP is growing, what is the relationship between the inflation rate and money growth rate?
