Financial Markets and the Economy

Financial Markets are markets in which funds accumulated by one

group are made available to another group.

The bond market is a market in which institutions and individuals borrow and lend money. They do

this through buying and selling bonds.

For example, the U.S. government wishes to borrow money. They issue a bond like

this one. It will have a date of maturity, or when you can turn it back into the

government and get your money back

It will also have the amount of money you get paid back, in this case $100. So let’s say the maturity on this bond

is one year.

You buy it now and turn give it to the government in one year to be paid $100. You are loaning them your money for one year. What is the

interest rate you are getting?

That depends on how much you paid for it.

Let’s say you pay $90 for it. In one year, you get back $100.

You have lent $90 for a year and got back $100. That is equal to an interest

rate of (Face Value – Bond Price)/Bond Price

($100-$90)/$90 = $10/$90 = .1111= 11.11%

The higher the price you pay for the $100 bond 1 year bond, the lower the interest rate you get.

Pay $90, then i = 11.1%Pay $95, then i = 5.3% Pay $99, then i = 1.0%

So now we face a choice. Do we want to think of the bond market

as one where people lend and borrow money at a certain interest

rate, or buy and sell bonds at a certain price?

Both of these are correct ways of illustrating the same thing

happening. Textbook guy uses the 2nd way. I find the 1st way much

more intuitive.

Here are both ways side-by-side. We will primarily use the diagram on the right.

You’ve seen the 2nd diagram before back in unit 2, where I called it the supply and demand diagram for the credit market.

Here is one way that a change in interest rates can effect the macroeconomy.

Much investment spending done by businesses is financed through

borrowing. The higher the interest rate you have to pay on a loan to get the

money to build a new factory, the less likely you are to build the factory.

Suppose for some reason there is an increase in the amount available for lending. This is an

increase in supply in the credit market.Interest rate

Q1 Q2

You have a demand for money. Do you always want more?

What can you do with your purchasing power? 3 things.

1) Buy Goods2) Buy bonds (or other high

interest investments)3) Hold it as money

1) Why buy goods?That’s obvious. You want them.

2) Why buy bonds?To earn interest.

3) Why hold money?Purchase future goods and services

easily. Money is very liquid.

3 Reasons to be holding money

1) Holding money to make expected purchases later is the transactions

demand for money.

2) Holding money to protect against unexpected purchases (emergencies) is the precautionary demand for money.

3) The speculative demand for money you expect to invest in

bonds or stocks but are waiting for a better price.

If we look just at the choice to hold money or bonds, we can think of the interest rate as the opportunity cost

or “price” of holding money.

If the money itself earns interest, such as an interest earning checking

out, it is the difference in the two interest rates that matters.

The higher the interest rate goes on the bonds you have to give up

to hold money, the less money you want to hold.

Or the more bonds you want to hold. The two statements are

functionally equivalent.

Demand curve for money in terms of interest for bonds.

What else affects the demand for money?

1) Expected inflation – the more you expect prices to rise, the less cash you want to hold (remember the wealth

effect?)2) Confidence in the future – if you fear losing your job or that the bond you buy may not pay off, you wish to hold more

cash.

Textbook guy lists a few more, but you do not have to memorize the

others on the list.

I fear losing my job.

What about the supply of money. Let’s assume the federal reserve

board can create as much or little money as it wishes through

open market operations.

Equilibrium in the money market is when people want to hold exactly

as much money as the fed has created. Suppose the interest rate is very high. People won’t want to

hold much money, they will want to hold bonds instead. If the Fed has created a lot of money, people will

have “too much” money.

They will get rid of the excess by saving it into the bond market.

They will do this by buying bonds. The interest rate will fall until

people no longer feel they have “too much” money.

Do people really think they have too much money? Well, imagine you

have a huge cash stash in the cookie jar and read that Ford Auto Co. is

paying 100% on Ford bonds.

Wouldn’t you say I have too much cash sitting around doing nothing when it could be earning 100%?

If they have “too little” money, they will get more by saving less into the

bond market (selling bonds) and interest rates will rise.

There will be an interest rate at which people want to hold the

exact amount of money created by the Fed.

When we get to that interest rate, there will be equilibrium in the money market.

The money market graph and the credit market graphs are two sides of

the same coin.

If the demand curve for money shifts, the interest rate will shift. Suppose

people fear a big rise in inflation.

More money goes into the bond market and interest rates fall.

If the Fed creates more money, people put some of that money into the bond

market and interest rates fall.

Here we see what is simultaneously happening in the credit market.

Chapter 11

Monetary Policy and the Fed

What are the Fed’s goals?

1) Low Inflation2) Low Unemployment

3) High Growth

The same 3 variables that we said determine if the macroeconomy is

working well back at the beginning of chapter 5.

But what weight does it assign to each goal? In the 1960’s and 70’s, it was lower unemployment. Since then, it has been lower inflation.

This comes from the feeling among many bankers and economists that

the fed paid to little attention to inflation in the 60’s/70’s.

If it did, it was probably acting on the feeling that the fed paid too little attention to unemployment in the

1930’s.

Some economists are arguing that this “don’t make the same mistake we made last time” mentality is causing the fed to pay too much attention to

inflation now.

In theory, Congress can legally set the goals for the fed whenever it wants. It has given the fed a dual mandate of low unemployment

and low inflation.

In practice, this has left the fed almost completely independent.

So what should the fed do? Suppose we are in a recession. In our model,

Q is in the recessionary gap.

How can we get out of the recession? We could wait until

wages adjust, but with sticky wages, that could take years … and years.

A quicker way out would be if the fed could get AD to move right.

Q1

Can they do this?

The short answer is yes. 1) Fed buys government securities.2) Banks have more funds to loan.

3) Drop in interest rates.4) People borrow the new money

from the banks and buy things.

Voila, recession over!

This is known as expansionary monetary policy. The fed creates

money and drives down the interest rate to increase buying.

AD moves to the right and increases output and lowers

unemployment.

We’ve already seen what simultaneously is happening in the

credit market.Interest rate

Q1 Q2

Interest Rates Fall

What about in the money market? And buy this, I don’t mean the financial market sometimes known as the money market. I mean people’s choice of how much money

to hold.

Interest rates fall, people want to hold more money and less bonds.

So as the fed increases the money supply, people will hold more in their

cash stash. The increase in money to be lent will not be as large as the amount

created by the fed, since people will respond by saving less and holding

more cash. But it is unlikely this effect will be large enough to cancel out the

effect of the fed’s action.

But what if the problem is we are in the inflationary gap part of the diagram. Can we get back to QN without inflation? Not if we wait

for the natural long-run adjustment and the shifting SRAS curve. But what if we move AD to

the left?

Q

P

Out of the inflationary gap without inflation.

Q1

To do this, we use contractionary monetary policy. The fed decreases the money supply, this decreasing AD. After all, what is money used for? So less money, less buying.

1) Sell government securities.2) raise r.

3 raise the discount rate.

So to sum up:

To fight recessions, expansionary monetary policy to move AD right.

To fight inflation, contractionary fiscal policy to move AD left.

Well, that sounds easy. In fact, it sounds too easy. If

macroeconomics is that simple, why do we have such a hard problem with recessions and

inflation?
