Government and Fiscal Policy

A Massive Stimulus

Shaken by the severity of the recession that began in December 2007, Congress passed a huge $787 billion stimulus package in February 2009. President Obama described the measure as only “the beginning” of what the federal government ultimately would do to right the economy.

Roughly a third of the Recovery and Reinvestment Act is for a variety of tax cuts for individuals and firms. For example, each worker making less than $75,000 a year will receive $400 ($800 for a working couple earning up to $150,000) as a kind of rebate for payroll taxes. That works out to $8 a week. Qualifying college students are eligible for $2,500 tax credits for educational expenses. The other two-thirds is for a variety of government spending programs. The president said that the measure would “ignite spending by businesses and consumers … and make the investment necessary for lasting growth and economic prosperity.”Barack Obama, Weekly Address of the President to the Nation, February 14, 2009.

The measure illustrates an important difficulty of using fiscal policy in an effort to stabilize economic activity. It was passed over a year after the recession began. According to an estimate by the Congressional Budget Office (CBO), only about 20% of the spending called for by the legislation will take place in 2009, rising to about two-thirds through the middle of 2010. It is a guess what state the economy will be in then.

A fiscal stimulus package of over $150 billion had already been tried earlier in February 2008. It included $100 billion in tax rebates to households—up to $600 for individuals and $1,200 for couples— and over $50 billion in tax breaks for businesses. The boost to aggregate demand seemed slight—consumers saved much of their rebate money. In November 2008, unemployment insurance benefits were extended for seven additional weeks, in recognition of the growing unemployment problem.

President Obama argued that his proposals for dealing with the economy in the short term would, coincidentally, also promote long-term economic health. Some critics argued for a greater focus on tax cuts while others were concerned about whether the spending would focus on getting the greatest employment increase or be driven by political considerations.

How do government tax and expenditure policies affect real GDP and the price level? Why do economists differ so sharply in assessing the likely impact of such policies? Can fiscal policy be used to stabilize the economy in the short run? What are the long-run effects of government spending and taxing?

We begin with a look at the government’s budget to see how it spends the tax revenue it collects. Clearly, the government’s budget is not always in balance, so we will also look at government deficits and debt. We will then look at how fiscal policy works to stabilize the economy, distinguishing between built-in stabilization methods and discretionary measures. We will end the chapter with a discussion of why fiscal policy is so controversial.

As in the previous chapter on monetary policy, our primary focus will be U.S. policy. However, the tools available to governments around the world are quite similar, as are the issues surrounding the use of fiscal policy.

Financial Markets and the Economy

Clamping Down on Money Growth

For nearly three decades, Americans have come to expect very low inflation, on the order of 2% to 3% a year. How did this expectation come to be? Was it always so? Absolutely not.

In July 1979, with inflation approaching 14% and interest rates on three-month Treasury bills soaring past 10%, a desperate President Jimmy Carter took action. He appointed Paul Volcker, the president of the New York Federal Reserve Bank, as chairman of the Fed’s Board of Governors. Mr. Volcker made clear that his objective as chairman was to bring down the inflation rate—no matter what the consequences for the economy. Mr. Carter gave this effort his full support.

Mr. Volcker wasted no time in putting his policies to work. He slowed the rate of money growth immediately. The economy’s response was swift; the United States slipped into a brief recession in 1980, followed by a crushing recession in 1981–1982. In terms of the goal of reducing inflation, Mr. Volcker’s monetary policies were a dazzling success. Inflation plunged below a 4% rate within three years; by 1986 the inflation rate had fallen to 1.1%. The tall, bald, cigar-smoking Mr. Volcker emerged as a folk hero in the fight against inflation. Indeed he has returned 20 years later as part of President Obama’s economic team to perhaps once again rescue the U.S. economy.

The Fed’s seven-year fight against inflation from 1979 to 1986 made the job for Alan Greenspan, Mr. Volcker’s successor, that much easier. To see how the decisions of the Federal Reserve affect key macroeconomic variables—real GDP, the price level, and unemployment—in this chapter we will explore how financial markets, markets in which funds accumulated by one group are made available to another group, are linked to the economy.

This chapter provides the building blocks for understanding financial markets. Beginning with an overview of bond and foreign exchange markets, we will examine how they are related to the level of real GDP and the price level. The second section completes the model of the money market. We have learned that the Fed can change the amount of reserves in the banking system, and that when it does the money supply changes. Here we explain money demand—the quantity of money people and firms want to hold—which, together with money supply, leads to an equilibrium rate of interest.

The model of aggregate demand and supply shows how changes in the components of aggregate demand affect GDP and the price level. In this chapter, we will learn that changes in the financial markets can affect aggregate demand—and in turn can lead to changes in real GDP and the price level. Showing how the financial markets fit into the model of aggregate demand and aggregate supply we developed earlier provides a more complete picture of how the macroeconomy works.

Supply

What determines the quantity of a good or service sellers are willing to offer for sale? Price is one factor; ceteris paribus, a higher price is likely to induce sellers to offer a greater quantity of a good or service. Production cost is another determinant of supply. Variables that affect production cost include the prices of factors used to produce the good or service, returns from alternative activities, technology, the expectations of sellers, and natural events such as weather changes. Still another factor affecting the quantity of a good that will be offered for sale is the number of sellers—the greater the number of sellers of a particular good or service, the greater will be the quantity offered at any price per time period.

Price and the Supply Curve

The quantity supplied of a good or service is the quantity sellers are willing to sell at a particular price during a particular period, all other things unchanged. Ceteris paribus, the receipt of a higher price increases profits and induces sellers to increase the quantity they supply.

In general, when there are many sellers of a good, an increase in price results in an increase in quantity supplied, and this relationship is often referred to as the law of supply. We will see, though, through our exploration of microeconomics, that there are a number of exceptions to this relationship. There are cases in which a higher price will not induce an increase in quantity supplied. Goods that cannot be produced, such as additional land on the corner of Park Avenue and 56th Street in Manhattan, are fixed in supply—a higher price cannot induce an increase in the quantity supplied. There are even cases, which we investigate in microeconomic analysis, in which a higher price induces a reduction in the quantity supplied.

Generally speaking, however, when there are many sellers of a good, an increase in price results in a greater quantity supplied. The relationship between price and quantity supplied is suggested in a supply schedule, a table that shows quantities supplied at different prices during a particular period, all other things unchanged. Figure 3.8 “A Supply Schedule and a Supply Curve” gives a supply schedule for the quantities of coffee that will be supplied per month at various prices, ceteris paribus. At a price of $4 per pound, for example, producers are willing to supply 15 million pounds of coffee per month. A higher price, say $6 per pound, induces sellers to supply a greater quantity—25 million pounds of coffee per month.

Figure 3.8 A Supply Schedule and a Supply Curve

The supply schedule shows the quantity of coffee that will be supplied in the United States each month at particular prices, all other things unchanged. The same information is given graphically in the supply curve. The values given here suggest a positive relationship between price and quantity supplied.

A supply curve is a graphical representation of a supply schedule. It shows the relationship between price and quantity supplied during a particular period, all other things unchanged. Because the relationship between price and quantity supplied is generally positive, supply curves are generally upward sloping. The supply curve for coffee in Figure 3.8 “A Supply Schedule and a Supply Curve” shows graphically the values given in the supply schedule.

A change in price causes a movement along the supply curve; such a movement is called a change in quantity supplied. As is the case with a change in quantity demanded, a change in quantity supplied does not shift the supply curve. By definition, it is a movement along the supply curve. For example, if the price rises from $6 per pound to $7 per pound, the quantity supplied rises from 25 million pounds per month to 30 million pounds per month. That’s a movement from point A to point B along the supply curve in Figure 3.8 “A Supply Schedule and a Supply Curve”.

Changes in Supply

When we draw a supply curve, we assume that other variables that affect the willingness of sellers to supply a good or service are unchanged. It follows that a change in any of those variables will cause a change in supply, which is a shift in the supply curve. A change that increases the quantity of a good or service supplied at each price shifts the supply curve to the right. Suppose, for example, that the price of fertilizer falls. That will reduce the cost of producing coffee and thus increase the quantity of coffee producers will offer for sale at each price. The supply schedule in Figure 3.9 “An Increase in Supply” shows an increase in the quantity of coffee supplied at each price. We show that increase graphically as a shift in the supply curve from S1 to S2. We see that the quantity supplied at each price increases by 10 million pounds of coffee per month. At point A on the original supply curve S1, for example, 25 million pounds of coffee per month are supplied at a price of $6 per pound. After the increase in supply, 35 million pounds per month are supplied at the same price (point A′ on curve S2).

Figure 3.9 An Increase in Supply

If there is a change in supply that increases the quantity supplied at each price, as is the case in the supply schedule here, the supply curve shifts to the right. At a price of $6 per pound, for example, the quantity supplied rises from the previous level of 25 million pounds per month on supply curve S1 (point A) to 35 million pounds per month on supply curve S2 (point A′).

An event that reduces the quantity supplied at each price shifts the supply curve to the left. An increase in production costs and excessive rain that reduces the yields from coffee plants are examples of events that might reduce supply. Figure 3.10 “A Reduction in Supply” shows a reduction in the supply of coffee. We see in the supply schedule that the quantity of coffee supplied falls by 10 million pounds of coffee per month at each price. The supply curve thus shifts from S1 to S3.

Figure 3.10 A Reduction in Supply

A change in supply that reduces the quantity supplied at each price shifts the supply curve to the left. At a price of $6 per pound, for example, the original quantity supplied was 25 million pounds of coffee per month (point A). With a new supply curve S3, the quantity supplied at that price falls to 15 million pounds of coffee per month (point A″).

A variable that can change the quantity of a good or service supplied at each price is called a supply shifter. Supply shifters include (1) prices of factors of production, (2) returns from alternative activities, (3) technology, (4) seller expectations, (5) natural events, and (6) the number of sellers. When these other variables change, the all-other-things-unchanged conditions behind the original supply curve no longer hold. Let us look at each of the supply shifters.

Prices of Factors of Production

A change in the price of labor or some other factor of production will change the cost of producing any given quantity of the good or service. This change in the cost of production will change the quantity that suppliers are willing to offer at any price. An increase in factor prices should decrease the quantity suppliers will offer at any price, shifting the supply curve to the left. A reduction in factor prices increases the quantity suppliers will offer at any price, shifting the supply curve to the right.

Suppose coffee growers must pay a higher wage to the workers they hire to harvest coffee or must pay more for fertilizer. Such increases in production cost will cause them to produce a smaller quantity at each price, shifting the supply curve for coffee to the left. A reduction in any of these costs increases supply, shifting the supply curve to the right.

Returns from Alternative Activities

To produce one good or service means forgoing the production of another. The concept of opportunity cost in economics suggests that the value of the activity forgone is the opportunity cost of the activity chosen; this cost should affect supply. For example, one opportunity cost of producing eggs is not selling chickens. An increase in the price people are willing to pay for fresh chicken would make it more profitable to sell chickens and would thus increase the opportunity cost of producing eggs. It would shift the supply curve for eggs to the left, reflecting a decrease in supply.

Technology

A change in technology alters the combinations of inputs or the types of inputs required in the production process. An improvement in technology usually means that fewer and/or less costly inputs are needed. If the cost of production is lower, the profits available at a given price will increase, and producers will produce more. With more produced at every price, the supply curve will shift to the right, meaning an increase in supply.

Impressive technological changes have occurred in the computer industry in recent years. Computers are much smaller and are far more powerful than they were only a few years ago—and they are much cheaper to produce. The result has been a huge increase in the supply of computers, shifting the supply curve to the right.

While we usually think of technology as enhancing production, declines in production due to problems in technology are also possible. Outlawing the use of certain equipment without pollution-control devices has increased the cost of production for many goods and services, thereby reducing profits available at any price and shifting these supply curves to the left.

Seller Expectations

All supply curves are based in part on seller expectations about future market conditions. Many decisions about production and selling are typically made long before a product is ready for sale. Those decisions necessarily depend on expectations. Changes in seller expectations can have important effects on price and quantity.

Consider, for example, the owners of oil deposits. Oil pumped out of the ground and used today will be unavailable in the future. If a change in the international political climate leads many owners to expect that oil prices will rise in the future, they may decide to leave their oil in the ground, planning to sell it later when the price is higher. Thus, there will be a decrease in supply; the supply curve for oil will shift to the left.

Natural Events

Storms, insect infestations, and drought affect agricultural production and thus the supply of agricultural goods. If something destroys a substantial part of an agricultural crop, the supply curve will shift to the left. The terrible cyclone that killed more than 50,000 people in Myanmar in 2008 also destroyed some of the country’s prime rice growing land. That shifted the supply curve for rice to the left. If there is an unusually good harvest, the supply curve will shift to the right.

The Number of Sellers

The supply curve for an industry, such as coffee, includes all the sellers in the industry. A change in the number of sellers in an industry changes the quantity available at each price and thus changes supply. An increase in the number of sellers supplying a good or service shifts the supply curve to the right; a reduction in the number of sellers shifts the supply curve to the left.

The market for cellular phone service has been affected by an increase in the number of firms offering the service. Over the past decade, new cellular phone companies emerged, shifting the supply curve for cellular phone service to the right.

What Is Money?

If cigarettes and mackerel can be used as money, then just what is money? Money is anything that serves as a medium of exchange. A medium of exchange is anything that is widely accepted as a means of p*****t. In Romania under Communist Party rule in the 1980s, for example, Kent cigarettes served as a medium of exchange; the fact that they could be exchanged for other goods and services made them money.

Money, ultimately, is defined by people and what they do. When people use something as a medium of exchange, it becomes money. If people were to begin accepting basketballs as p*****t for most goods and services, basketballs would be money. We will learn in this chapter that changes in the way people use money have created new types of money and changed the way money is measured in recent decades.

The Functions of Money

Money serves three basic functions. By definition, it is a medium of exchange. It also serves as a unit of account and as a store of value—as the “mack” did in Lompoc.

A Medium of Exchange

The exchange of goods and services in markets is among the most universal activities of human life. To facilitate these exchanges, people settle on something that will serve as a medium of exchange—they select something to be money.

We can understand the significance of a medium of exchange by considering its absence. Barter occurs when goods are exchanged directly for other goods. Because no one item serves as a medium of exchange in a barter economy, potential buyers must find things that individual sellers will accept. A buyer might find a seller who will trade a pair of shoes for two chickens. Another seller might be willing to provide a haircut in exchange for a garden hose. Suppose you were visiting a grocery store in a barter economy. You would need to load up a truckful of items the grocer might accept in exchange for groceries. That would be an uncertain affair; you could not know when you headed for the store which items the grocer might agree to trade. Indeed, the complexity—and cost—of a visit to a grocery store in a barter economy would be so great that there probably would not be any grocery stores! A moment’s contemplation of the difficulty of life in a barter economy will demonstrate why human societies invariably select something—sometimes more than one thing—to serve as a medium of exchange, just as prisoners in federal penitentiaries accepted mackerel.

A Unit of Account

Ask someone in the United States what he or she paid for something, and that person will respond by quoting a price stated in dollars: “I paid $75 for this radio,” or “I paid $15 for this pizza.” People do not say, “I paid five pizzas for this radio.” That statement might, of course, be literally true in the sense of the opportunity cost of the transaction, but we do not report prices that way for two reasons. One is that people do not arrive at places like Radio Shack with five pizzas and expect to purchase a radio. The other is that the information would not be very useful. Other people may not think of values in pizza terms, so they might not know what we meant. Instead, we report the value of things in terms of money.

Money serves as a unit of account, which is a consistent means of measuring the value of things. We use money in this fashion because it is also a medium of exchange. When we report the value of a good or service in units of money, we are reporting what another person is likely to have to pay to obtain that good or service.

A Store of Value

The third function of money is to serve as a store of value, that is, an item that holds value over time. Consider a $20 bill that you accidentally left in a coat pocket a year ago. When you find it, you will be pleased. That is because you know the bill still has value. Value has, in effect, been “stored” in that little piece of paper.

Money, of course, is not the only thing that stores value. Houses, office buildings, land, works of art, and many other commodities serve as a means of storing wealth and value. Money differs from these other stores of value by being readily exchangeable for other commodities. Its role as a medium of exchange makes it a convenient store of value.

Because money acts as a store of value, it can be used as a standard for future payments. When you borrow money, for example, you typically sign a contract pledging to make a series of future payments to settle the debt. These payments will be made using money, because money acts as a store of value.

Money is not a risk-free store of value, however. We saw in the chapter that introduced the concept of inflation that inflation reduces the value of money. In periods of rapid inflation, people may not want to rely on money as a store of value, and they may turn to commodities such as land or gold instead.

Types of Money

Although money can take an extraordinary variety of forms, there are really only two types of money: money that has intrinsic value and money that does not have intrinsic value.

Commodity money is money that has value apart from its use as money. Mackerel in federal prisons is an example of commodity money. Mackerel could be used to buy services from other prisoners; they could also be eaten.

Gold and silver are the most widely used forms of commodity money. Gold and silver can be used as jewelry and for some industrial and medicinal purposes, so they have value apart from their use as money. The first known use of gold and silver coins was in the Greek city-state of Lydia in the beginning of the seventh century B.C. The coins were fashioned from electrum, a natural mixture of gold and silver.

One disadvantage of commodity money is that its quantity can fluctuate erratically. Gold, for example, was one form of money in the United States in the 19th century. Gold discoveries in California and later in Alaska sent the quantity of money soaring. Some of this nation’s worst bouts of inflation were set off by increases in the quantity of gold in circulation during the 19th century. A much greater problem exists with commodity money that can be produced. In the southern part of colonial America, for example, tobacco served as money. There was a continuing problem of farmers increasing the quantity of money by growing more tobacco. The problem was sufficiently serious that vigilante squads were organized. They roamed the countryside burning tobacco fields in an effort to keep the quantity of tobacco, hence money, under control. (Remarkably, these squads sought to control the money supply by burning tobacco grown by other farmers.)

Another problem is that commodity money may vary in quality. Given that variability, there is a tendency for lower-quality commodities to drive higher-quality commodities out of circulation. Horses, for example, served as money in colonial New England. It was common for loan obligations to be stated in terms of a quantity of horses to be paid back. Given such obligations, there was a tendency to use lower-quality horses to pay back debts; higher-quality horses were kept out of circulation for other uses. Laws were passed forbidding the use of lame horses in the p*****t of debts. This is an example of Gresham’s law: the tendency for a lower-quality commodity (bad money) to drive a higher-quality commodity (good money) out of circulation. Unless a means can be found to control the quality of commodity money, the tendency for that quality to decline can threaten its acceptability as a medium of exchange.

But something need not have intrinsic value to serve as money. Fiat money is money that some authority, generally a government, has ordered to be accepted as a medium of exchange. The currency—paper money and coins—used in the United States today is fiat money; it has no value other than its use as money. You will notice that statement printed on each bill: “This note is legal tender for all debts, public and private.”

Checkable deposits, which are balances in checking accounts, and traveler’s checks are other forms of money that have no intrinsic value. They can be converted to currency, but generally they are not; they simply serve as a medium of exchange. If you want to buy something, you can often pay with a check or a debit card. A check is a written order to a bank to transfer ownership of a checkable deposit. A debit card is the electronic equivalent of a check. Suppose, for example, that you have $100 in your checking account and you write a check to your campus bookstore for $30 or instruct the clerk to swipe your debit card and “charge” it $30. In either case, $30 will be transferred from your checking account to the bookstore’s checking account. Notice that it is the checkable deposit, not the check or debit card, that is money.

The Nature and Creation of Money

Larry Levine helped a client prepare divorce papers a few years ago. He was paid in mackerel.

“It’s the coin of the realm,” his client, Mark Bailey told the Wall Street Journal. The two men were prisoners at the time at the federal penitentiary at Lompoc, California.

By the time his work on the case was completed, he had accumulated “a stack of macks,” Mr. Levine said. He used his fishy hoard to buy items such as haircuts at the prison barber shop, to have his laundry pressed, or to have his cell cleaned.

The somewhat unpleasant fish emerged as the currency of choice in many federal prisons in 1994 when cigarettes, the previous commodity used as currency, were banned. Plastic bags of mackerel sold for about $1 in prison commissaries. Almost no one likes them, so the prison money supply did not get eaten. Prisoners knew other prisoners would readily accept macks, so they were accepted in exchange for goods and services. Their $1 price made them convenient as a unit of account. And, as Mr. Levine’s experience suggests, they acted as a store of value. As we shall see, macks served all three functions of money—they were a medium of exchange, a unit of account, and a store of value.Justin Scheck, “Mackerel Economics in Prison Leads to Appreciation for Oily Fish,” Wall Street Journal, October 2, 2008, p. A1.

In this chapter and the next we examine money and the way it affects the level of real GDP and the price level. In this chapter, we will focus on the nature of money and the process through which it is created.

As the experience of the prisoners in Lompoc suggests, virtually anything can serve as money. Historically, salt, horses, tobacco, cigarettes, gold, and silver have all served as money. We shall examine the characteristics that define a good as money.

We will also introduce the largest financial institution in the world, the Federal Reserve System of the United States. The Fed, as it is commonly called, plays a key role in determining the quantity of money in the United States. We will see how the Fed operates and how it attempts to control the supply.
