1. The level of prices and the value of money
Suppose the price level reflects the number of dollars needed to buy a basket of goods containing one can of seltzer, one bag of pretzels, and one shuttle ride. In year one, the basket costs $9.00.
In year two, the price of the same basket is $8.00. From year one to year two, there is at an annual rate of .
In year one, $72.00 will buy baskets, and in year two, $72.00 will buy baskets.
This example illustrates that, as the price level falls, the value of money .

2. Money supply, money demand, and adjustment to monetary equilibrium
The following table gives the quantity of money demanded at various price levels (P�), the money demand schedule.
In the following table, fill in the column labeled Value of Money.
Price Level (P)
Value of Money (1/P)
Quantity of Money Demanded
(Billions of dollars)
0.80

Now consider the relationship between the quantity of money that people demand and the price level. The lower the price level, the money required to complete transactions, and the money people will want to hold in the form of currency or demand deposits.
Assume that the Federal Reserve initially fixes the quantity of money supplied at $4 billion.
Use the orange line (square symbol) to plot the initial money supply (MS1MS1) set by the Fed. Then, referring to the previous table, use the blue connected points (circle symbol) to graph the money demand curve.
According to your graph, the equilibrium value of money is , therefore the equilibrium price level is .
Now, suppose that the Fed reduces the money supply from the initial level of $4 billion to $2.5 billion.
In order to reduce the money supply, the Fed can use open market operations to the public.
Use the purple line (diamond symbol) to plot the new money supply (MS2MS2).
Immediately after the Fed changes the money supply from its initial equilibrium level, the quantity of money supplied is than the quantity of money demanded at the initial equilibrium. This contraction in the money supply will people's demand for goods and services. In the long run, since the economy's ability to produce goods and services has not changed, the prices of goods and services will and the value of money will .

Now consider the relationship between the quantity of money that people demand and the price level. The higher the price level, the money required to complete transactions, and the money people will want to hold in the form of currency or demand deposits.
Assume that the Federal Reserve initially fixes the quantity of money supplied at $3.5 billion.

Use the purple line (diamond symbol) to plot the new money supply (MS2MS2).
Immediately after the Fed changes the money supply from its initial equilibrium level, the quantity of money supplied is than the quantity of money demanded at the initial equilibrium.

7. Identifying costs of inflation
Meagan owns and operates a store in a country experiencing a high rate of inflation. Each day, some of her employees spend time tracking changes in the overall price level and changing the price tags within the store and the price lists on the store's website. This is an example of the of inflation.
Victor manages a grocery store in a country experiencing a high rate of inflation. He is paid in cash twice per month. On payday, he immediately goes out and buys all the goods he will need over the next two weeks in order to prevent the money in his wallet from losing value. What he can't spend, he converts into a more stable foreign currency for a steep fee. This is an example of the of inflation.
Rod manages a grocery store in a country experiencing a high rate of inflation. To keep up with inflation, he spends a lot of time every day updating the prices, printing new price tags, and sending out newspaper inserts advertising the new prices. His employees regularly deal with customer annoyance over the frequent price changes. This is an example of the of inflation.
