Monetary Policy and Interest
• Monetary policy is the behavior of the Central Bank concerning the money supply.
• Interest is the fee that borrowers pay to lenders for the use of their funds.
• Interest rate is the annual interest payment on a loan expressed as a percentage of the loan.

The Demand for Money
• The main concern in the study of the demand for money is:
• How much of your financial assets you want to hold in the form of money, which does not earn interest, versus how much you want to hold in interest-bearing securities, such as bonds.

The Transaction Motive
• There is a trade-off between the liquidity of money and the interest income offered by other kinds of assets.
• The transaction motive is the main reason that people hold money—to buy things.

The Transaction Motive
Simplifying assumptions in the study of the demand for money:
• There are only two kinds of assets available to households: bonds and money.
• The typical household’s income arrives once a month, at the beginning of the month.
• Spending occurs at a completely uniform rate—the same amount is spent each day.
• Spending is exactly equal to income for the month.

The Nonsynchronizationof Income and Spending
• The mismatch between the timing of money inflow to the household and the timing of money outflow for household expenses is called the nonsynchronization of income and spending.
• Income arrives only once a month, but spending takes place continuously.

Money Management
• Selim could decide to deposit his entire paycheck ($1,200) into his checking account at the start of the month and run his balance down to zero by the end of the month.
• In this case, his average money holdings would be $600.

Money Management
• Selim could decide to deposit half of his paycheck ($1,200) into his checking account, and buy a $600 bond with the other half. At mid-month, he could sell the bond and deposit the $600 into his checking account.
• Month over month, his average money holdings would be $300.

The Optimal Balance
• There is a level of average money holdings that earns Selim the most profit, taking into account both the interest earned on bonds and the cost paid for switching from bonds to money. This level is his optimal balance.
• An increase in the interest rate lowers the optimal money balance. People want to take advantage of the high return on bonds, so they choose to hold very little money.

The Speculation Motive
• The speculation motive: Because the market value of interest-bearing bonds is inversely related to the interest rate, investors may wish to hold bonds when interest rates are high with the hope of selling them when interest rates fall.

The Speculation Motive
• If someone buys a 10-year bond with a fixed rate of 10%, and a newly issued 10-year bond pays 12%, then the old bond paying 10% will have fallen in value.
• Higher bond prices mean that the interest a buyer is willing to accept is lower than before.
• When interest rates are high (low) and expected to fall (rise), demand for bonds is likely to be high (low) thus money demand is likely to be low (high).

The Total Demand for Money
• The total quantity of money demanded in the economy is the sum of the demand for checking account balances and cash by both households and firms.

The Total Demand for Money
• The quantity of money demanded at any moment depends on the opportunity cost of holding money, a cost determined by the interest rate.
• A higher interest rate raises the opportunity cost of holding money and thus reduces the quantity of money demanded.

Transactions Volumeand the Price Level
• The total demand for money in the economy depends on the total dollar value of transactions made.
• The total dollar volume of transactions, in turn, depends on aggregate income and overall price level.

The Determinants ofMoney Demand: Review
• Money demand is a stock variable, measured at a given point in time.
Determinants of Money Demand
1. The interest rate: r (negative effect)
2. The dollar volume of transactions (positive effect)
a. Aggregate output (income): Y (positive effect)
b. The price level: P (positive effect)

The Determinants ofMoney Demand: Review
• Money demand answers the question:
• How much money do firms and households desire to hold at a specific point in time, given the current interest rate, volume of economic activity, and price level?

The Equilibrium Interest Rate
• The point at which the quantity of money demanded equals the quantity of money supplied determines the equilibrium interest rate in the economy.

The Equilibrium Interest Rate
• At r1, the amount of money in circulation is higher than households and firms wish to hold. Interest rates must fall to encourage people to hold more money and fewer bonds.

The Equilibrium Interest Rate
• At r2, households don’t have enough money to facilitate ordinary transactions. People wil sell bonds in order to increase their money holdings. This drives down bond prices and causes interest rates to rise.

• An increase in the supply of money lowers the rate of interest.

Increases in Y and Shiftsin the Money Demand Curve
• An increase in aggregate output (income) shifts the money demand curve, which raises the equilibrium interest rate.
• An increase in the price level has the same effect.

Looking Ahead: Central Bank and Monetary Policy
• Tight monetary policy refers to the CB policies that contract the money supply in an effort to restrain the economy.
• Easy monetary policy refers to the CB policies that expand the money supply in an effort to stimulate the economy.
