The Abilitytopay Principle

Another way to evaluate the equity of a tax system is called the ability-to-pay principle, which states that taxes should be levied on a person according to how well that person can shoulder the burden. This principle is sometimes justified by the claim that all citizens should make an equal sacrifice to support the government. The magnitude of a person's sacrifice, however, depends not only on the size of his tax payment but also on his income and other circumstances. A 1,000 tax paid by a...

The Aggregatedemand Curve

A fall in the price level from Pj to P2 increases the quantity of goods and services demanded from Yj to Y2. There are three reasons for this negative relationship. As the price level falls, real wealth rises, interest rates fall, and the exchange rate depreciates. These effects stimulate spending on consumption, investment, and net exports. Increased spending on these components of output means a larger quantity of goods and services demanded. 2. . . . increases the...

The Cost Of Capital As An Opportunity Cost

An important implicit cost of almost every business is the opportunity cost of the financial capital that has been invested in the business. Suppose, for instance, that Helen used 300,000 of her savings to buy her cookie factory from the previous owner. If Helen had instead left this money deposited in a savings account that pays an interest rate of 5 percent, she would have earned 15,000 per year. To own her cookie factory, therefore, Helen has given up 15,000 a year in interest income. This...

The Effects Of A Shift In Aggregate Demand

Suppose that for some reason a wave of pessimism suddenly overtakes the economy. The cause might be a scandal in the White House, a crash in the stock market, or the outbreak of a war overseas. Because of this event, many people lose confidence in the future and alter their plans. Households cut back on their spending and delay major purchases, and firms put off buying new equipment. What is the impact of such a wave of pessimism on the economy Such an event reduces the aggregate demand for...

The Federal Government

The U.S. federal government collects about two-thirds of the taxes in our economy. It raises this money in a number of ways, and it finds even more ways to spend it. Receipts Table 12-2 shows the receipts of the federal government in 1999. Total receipts in this year were 1,806 billion, a number so large that it is hard to comprehend. To bring this astronomical number down to earth, we can divide it by the size of the U.S. population, which was about 272 million in 1999. We then find that the...

The Fisher Effect

According to the principle of monetary neutrality, an increase in the rate of money growth raises the rate of inflation but does not affect any real variable. An important application of this principle concerns the effect of money on interest rates. Interest rates are important variables for macroeconomists to understand because they link the economy of the present and the economy of the future through their effects on saving and investment. To understand the relationship between money,...

The Lessons For Trade Policy

The team of Isolandian economists can now write to the new president You asked us three questions about opening up trade. After much hard work, we have the answers. Question If the government allowed Isolandians to import and export steel, what would happen to the price of steel and the quantity of steel sold in the domestic steel market Answer Once trade is allowed, the Isolandian price of steel would be driven to equal the price prevailing around the world. If the world price is now higher...

The Level Of Prices And The Value Of Money

Suppose we observe over some period of time the price of an ice-cream cone rising from a nickel to a dollar. What conclusion should we draw from the fact that people are willing to give up so much more money in exchange for a cone It is possible that people have come to enjoy ice cream more (perhaps because some chemist has developed a miraculous new flavor). Yet that is probably not the case. It is more likely that people's enjoyment of ice cream has stayed roughly the same and that, over...

The Meaning Of Money

The set of assets in an economy that people regularly use to buy goods and services from other people What is money This might seem like an odd question. When you read that billionaire Bill Gates has a lot of money, you know what that means He is so rich that he can buy almost anything he wants. In this sense, the term money is used to mean wealth. Economists, however, use the word in a more specific sense Money is the set of assets in the economy that people regularly use to buy goods and...

The Nationalsecurity Argument

When an industry is threatened with competition from other countries, opponents of free trade often argue that the industry is vital for national security. In our example, Isolandian steel companies might point out that steel is used to make guns and tanks. Free trade would allow Isoland to become dependent on foreign countries to supply steel. If a war later broke out, Isoland might be unable to produce enough steel and weapons to defend itself. Economists acknowledge that protecting key...

The Poverty Rate

The percentage of the population whose family income falls below an absolute level called the poverty line an absolute level of income set by the federal government for each family size below which a family is deemed to be in poverty A commonly used gauge of the distribution of income is the poverty rate. The poverty rate is the percentage of the population whose family income falls below an absolute level called the poverty line. The poverty line is set by the federal government at roughly...

The Price Elasticity Of Demand And Its Determinants

A measure of how much the quantity demanded of a good responds to a change in the price of that good, computed as the percentage change in quantity demanded divided by the percentage change in price The law of demand states that a fall in the price of a good raises the quantity demanded. The price elasticity of demand measures how much the quantity demanded responds to a change in price. Demand for a good is said to be elastic if the quantity demanded responds substantially to changes in the...

The Price Level and Investment The Interest Rate Effect

As we discussed in Chapter 28, the price level is one determinant of the quantity of money demanded. The lower the price level, the less money households need to hold to buy the goods and services they want. When the price level falls, therefore, households try to reduce their holdings of money by lending some of it out. For instance, a household might use its excess money to buy interest-bearing bonds. Or it might deposit its excess money in an interest-bearing savings account, and the bank...

The Relationship Between Shortrun And Longrun Average Total Cost

For many firms, the division of total costs between fixed and variable costs depends on the time horizon. Consider, for instance, a car manufacturer, such as Ford Motor Company. Over a period of only a few months, Ford cannot adjust the number or sizes of its car factories. The only way it can produce additional cars is to hire more workers at the factories it already has. The cost of these factories is, therefore, a fixed cost in the short run. By contrast, over a period of several years, Ford...

The Revenue Of A Competitive Firm

A firm in a competitive market, like most other firms in the economy, tries to maximize profit, which equals total revenue minus total cost. To see how it does this, we first consider the revenue of a competitive firm. To keep matters concrete, let's consider a specific firm the Smith Family Dairy Farm. The Smith Farm produces a quantity of milk Q and sells each unit at the market price P. The farm's total revenue is P X Q. For example, if a gallon of milk sells for 6 and the farm sells 1,000...

The Theory Of Liquidity Preference

In his classic book, The General Theory of Employment, Interest, and Money, John Maynard Keynes proposed the theory of liquidity preference to explain what factors determine the economy's interest rate. The theory is, in essence, just an application of supply and demand. According to Keynes, the interest rate adjusts to balance the supply and demand for money. You may recall from Chapter 23 that economists distinguish between two interest rates The nominal interest rate is the interest rate as...

The Winners And Losers From Trade

International Trade in an Exporting Country. Once trade is allowed, the domestic price rises to equal the world price. The supply curve shows the quantity of steel produced domestically, and the demand curve shows the quantity consumed domestically. Exports from Isoland equal the difference between the domestic quantity supplied and the domestic quantity demanded at the world price. Now consider the gains and losses from opening up trade. Clearly, not everyone benefits. Trade forces the...

Three Steps To Analyzing Changes In Equilibrium

So far we have seen how supply and demand together determine a market's equilibrium, which in turn determines the price of the good and the amount of the good that buyers purchase and sellers produce. Of course, the equilibrium price and quantity depend on the position of the supply and demand curves. When some event shifts one of these curves, the equilibrium in the market changes. The analysis of such a change is called comparative statics because it involves comparing two static situations...

Using The Demand Curve To Measure Consumer Surplus

Consumer surplus is closely related to the demand curve for a product. To see how they are related, let's continue our example and consider the demand curve for this rare Elvis Presley album. We begin by using the willingness to pay of the four possible buyers to find the demand schedule for the album. Table 7-2 shows the demand schedule that corresponds to Table 7-1. If the price is above 100, the quantity demanded in the market is 0, because no buyer is willing to pay that much. If the price...

What Causes The Labor Supply Curve To Shift

The labor supply curve shifts whenever people change the amount they want to work at a given wage. Let's now consider some of the events that might cause such a shift. Changes i n Tastes In 1950, 34 percent of women were employed at paid jobs or looking for work. In 1998, the number had risen to 60 percent. There are, of course, many explanations for this development, but one of them is changing tastes, or attitudes toward work. A generation or two ago, it was the norm for women to stay at home...

Why Productivity Is So Important

Let's begin our study of productivity and economic growth by developing a simple model based loosely on Daniel DeFoe's famous novel Robinson Crusoe. Robinson Crusoe, as you may recall, is a sailor stranded on a desert island. Because Crusoe lives alone, he catches his own fish, grows his own vegetables, and makes his own clothes. We can think of Crusoe's activities his production and consumption of fish, vegetables, and clothing as being a simple economy. By examining Crusoe's economy, we can...

Why Some Frictional Unemployment Is Inevitable

Frictional unemployment is often the result of changes in the demand for labor among different firms. When consumers decide that they prefer Compaq over Dell computers, Compaq increases employment, and Dell lays off workers. The former Dell workers must now search for new jobs, and Compaq must decide which new workers to hire for the various jobs that have opened up. The result of this transition is a period of unemployment. Similarly, because different regions of the country produce different...

Why The Aggregatedemand Curve Might Shift

The downward slope of the aggregate-demand curve shows that a fall in the price level raises the overall quantity of goods and services demanded. Many other factors, however, affect the quantity of goods and services demanded at a given price level. When one of these other factors changes, the aggregate-demand curve shifts. Let's consider some examples of events that shift aggregate demand. We can categorize them according to which component of spending is most directly affected. Shifts Arising...

Why The Aggregatesupply Curve Slopes Upward In The Short

We now come to the key difference between the economy in the short run and in the long run the behavior of aggregate supply. As we have already discussed, the long-run aggregate-supply curve is vertical. By contrast, in the short run, the aggregate-supply curve is upward sloping, as shown in Figure 31-6. That is, over a period of a year or two, an increase in the overall level of prices in the economy tends to raise the quantity of goods and services supplied, and a decrease in the level of...

Worker Quality

A fourth and final type of efficiency-wage theory emphasizes the link between wages and worker quality. When a firm hires new workers, it cannot perfectly gauge the quality of the applicants. By paying a high wage, the firm attracts a better pool of workers to apply for its jobs. To see how this might work, consider a simple example. Waterwell Company owns one well and needs one worker to pump water from the well. Two workers, Bill and Ted, are interested in the job. Bill, a proficient worker,...

How A Tax Affects Market Participants

Now let's use the tools of welfare economics to measure the gains and losses from a tax on a good. To do this, we must take into account how the tax affects buyers, sellers, and the government. The benefit received by buyers in a market is measured by consumer surplus the amount buyers are willing to pay for the good minus the amount they actually pay for it. The benefit received by sellers in a market is measured by producer surplus the amount sellers receive for the good minus their costs....

Unemployment And Its Natural Rate

Learn about the data used to measure the amount of unemployment Consider how unemployment arises from the process of job search Losing a job can be the most distressing economic event in a person's life. Most people rely on their labor earnings to maintain their standard of living, and many people get from their work not only income but also a sense of personal accomplishment. A job loss means a lower living standard in the present, anxiety about the future, and reduced self-esteem. It is not...

Some Important Public Goods

There are many examples of public goods. Here we consider three of the most important. Nati onal Defense The defense of the country from foreign aggressors is a classic example of a public good. It is also one of the most expensive. In 1999 the U.S. federal government spent a total of 277 billion on national defense, or about 1,018 per person. People disagree about whether this amount is too small or too large, but almost no one doubts that some government spending for national defense is...

Should Tiger Woods Mow His Own Lawn

Tiger Woods spends a lot of time walking around on grass. One of the most talented golfers of all time, he can hit a drive and sink a putt in a way that most casual golfers only dream of doing. Most likely, he is talented at other activities too. For example, let's imagine that Woods can mow his lawn faster than anyone else. But just because he can mow his lawn fast, does this mean he should To answer this question, we can use the concepts of opportunity cost and comparative advantage. Let's...

Measuring The Cost Of Living

Learn how the consumer price index (CPI) is constructed Consider why the CPI is an imperfect measure of the cost of living Compare the CPI and the GDP deflator as measures of the overall price level In 1931, as the U.S. economy was suffering through the Great Depression, famed baseball player Babe Ruth earned 80,000. At the time, this salary was extraordinary, even among the stars of baseball. According to one story, a reporter asked Ruth whether he thought it was right that he made more than...

Costs As Opportunity Costs

When measuring costs at Hungry Helen's Cookie Factory or any other firm, it is important to keep in mind one of the Ten Principles of Economics from Chapter 1 The cost of something is what you give up to get it. Recall that the opportunity cost of an item refers to all those things that must be forgone to acquire that item. When economists speak of a firm's cost of production, they include all the opportunity costs of making its output of goods and services. A firm's opportunity costs of...

Case Study The Laffer Curve And Supplyside Economics

One day in 1974, economist Arthur Laffer sat in a Washington restaurant with some prominent journalists and politicians. He took out a napkin and drew a figure on it to show how tax rates affect tax revenue. It looked much like panel (b) of our Figure 8-7. Laffer then suggested that the United States was on the downward-sloping side of this curve. Tax rates were so high, he argued, that reducing them would actually raise tax revenue. Most economists were skeptical of Laffer's suggestion. The...

Case Study Discrimination In Sports

As we have seen, measuring discrimination is often difficult. To determine whether one group of workers is discriminated against, a researcher must correct for differences in the productivity between that group and other workers in the economy. Yet, in most firms, it is difficult to measure a particular worker's contribution to the production of goods and services. One type of firm in which such corrections are easier is the sports team. Professional teams have many objective measures of...

Ability Effort And Chance

Why do major league baseball players get paid more than minor league players Certainly, the higher wage is not a compensating differential. Playing in the major leagues is not a less pleasant task than playing in the minor leagues in fact, the opposite is true. The major leagues do not require more years of schooling or more experience. To a large extent, players in the major leagues earn more just because they have greater natural ability. Natural ability is important for workers in all...

Con Policymakers Should Not Try To Stabilize The Economy

Although monetary and fiscal policy can be used to stabilize the economy in theory, there are substantial obstacles to the use of such policies in practice. One problem is that monetary and fiscal policy do not affect the economy immediately but instead work with a long lag. Monetary policy affects aggregate demand by changing interest rates, which in turn affect spending, especially residential and business investment. But many households and firms set their spending plans in advance. As a...

The Market For Loanable Funds

When we first analyzed the role of the financial system in Chapter 25, we made the simplifying assumption that the financial system consists of only one market, called the market for loanable funds. All savers go to this market to deposit their saving, and all borrowers go to this market to get their loans. In this market, there is one interest rate, which is both the return to saving and the cost of borrowing. To understand the market for loanable funds in an open economy, the place to start...

The Simple Case Of 100percentreserve Banking

To see how banks influence the money supply, it is useful to imagine first a world without any banks at all. In this simple world, currency is the only form of money. To be concrete, let's suppose that the total quantity of currency is 100. The supply of money is, therefore, 100. Now suppose that someone opens a bank, appropriately called First National Bank. First National Bank is only a depository institution that is, it accepts deposits but does not make loans. The purpose of the bank is to...

Why The Shortrun Aggregatesupply Curve Might Shift

The short-run aggregate-supply curve tells us the quantity of goods and services supplied in the short run for any given level of prices. We can think of this curve as similar to the long-run aggregate-supply curve but made upward sloping by the presence of misperceptions, sticky wages, and sticky prices. Thus, when think ing about what shifts the short-run aggregate-supply curve, we have to consider all those variables that shift the long-run aggregate-supply curve plus a new variable the...

The Case For Active Stabilization Policy

Let's return to the question that began this chapter When the president and Congress cut government spending, how should the Federal Reserve respond As we have seen, government spending is one determinant of the position of the aggregate-demand curve. When the government cuts spending, aggregate demand will fall, which will depress production and employment in the short run. If the Federal Reserve wants to prevent this adverse effect of the fiscal policy, it can act to expand aggregate demand...

Public Policy And Job Search

Even if some frictional unemployment is inevitable, the precise amount is not. The faster information spreads about job openings and worker availability, the more rapidly the economy can match workers and firms. The Internet, for instance, may help facilitate job search and reduce frictional unemployment. In addition, public policy may play a role. If policy can reduce the time it takes unemployed workers to find new jobs, it can reduce the economy's natural rate of unemployment. Government...

The Economics Of Unions

Like any cartel, a union is a group of sellers acting together in the hope of exerting their joint market power. Most workers in the U.S. economy discuss their wages, benefits, and working conditions with their employers as individuals. By contrast, workers in a union do so as a group. The process by which unions and firms agree on the terms of employment is called collective bargaining. When a union bargains with a firm, it asks for higher wages, better benefits,...

The Supply Curve In A Competitive Market

Now that we have examined the supply decision of a single firm, we can discuss the supply curve for a market. There are two cases to consider. First, we examine a market with a fixed number of firms. Second, we examine a market in which the number of firms can change as old firms exit the market and new firms enter. Both cases are important, for each applies over a specific time horizon. Over short periods of time, it is often difficult for firms to enter and exit, so the assumption of a fixed...

Case Study Two Ways To Reduce The Quantity Of Smoking Demanded

Two Ways Demand Curve

Public policymakers often want to reduce the amount that people smoke. There are two ways that policy can attempt to achieve this goal. One way to reduce smoking is to shift the demand curve for cigarettes and other tobacco products. Public service announcements, mandatory health warnings on cigarette packages, and the prohibition of cigarette advertising on television are all policies aimed at reducing the quantity of cigarettes demanded at any given price. If successful, these policies shift...

The Effects Of A Shift In Aggregate Supply

Imagine once again an economy in its long-run equilibrium. Now suppose that suddenly some firms experience an increase in their costs of production. For example, bad weather in farm states might destroy some crops, driving up the cost An Adverse Shift in Aggregate Supply. When some event increases firms' costs, the short-run aggregate-supply curve shifts to the left from AS to AS2. The economy moves from point A to point B. The result is stagflation Output falls from Y1 to Y2, and the price...

Political Instability And Capital Flight

In 1994 political instability in Mexico, including the assassination of a prominent political leader, made world financial markets nervous. People began to view Mexico as a much less stable country than they had previously thought. They decided to pull some of their assets out of Mexico in order to move these funds to the United States and other safe havens. Such a large and sudden movement of funds out of a country is called capital flight. To see the implications of capital flight for the...

Conclusion The Origins Of Aggregate Demand And Aggregate Supply

First, we have discussed some of the important facts about short-run fluctuations in economic activity. Second, we have introduced a basic model to explain those fluctuations, called the model of aggregate demand and aggregate supply.

The Various Measures Of Cost

Thirsty Thelma Lemonade Stand

Our analysis of Hungry Helen's Cookie Factory demonstrated how a firm's total cost reflects its production function. From data on a firm's total cost, we can derive several related measures of cost, which will turn out to be useful when we analyze production and pricing decisions in future chapters. To see how these related measures are derived, we consider the example in Table 13-2. This table presents cost data on Helen's neighbor Thirsty Thelma's Lemonade Stand. The first column of the table...

If an economy is to allocate its scarce resources efficiently, goods must get to those consumers who value them most highly. Ticket scalping is one example of how markets reach efficient outcomes. Scalpers buy tickets to plays, concerts, and sports events and then sell the tickets at a price above their original cost. By charging the highest price the market will bear, scalpers help ensure that consumers with the greatest willingness to pay for the tickets actually do get them. In some places,...

The Effects Of An Import Quota

The Isolandian economists next consider the effects of an import quota a limit on the quantity of imports. In particular, imagine that the Isolandian government distributes a limited number of import licenses. Each license gives the license holder the right to import 1 ton of steel into Isoland from abroad. The Isolandian economists want to compare welfare under a policy of free trade and welfare with the addition of this import quota. Figure 9-7 shows how an import quota affects the Isolandian...

Case Study Monopoly Drugs Versus Generic Drugs

According to our analysis, prices are determined quite differently in monopolized markets from the way they are in competitive markets. A natural place to test this theory is the market for pharmaceutical drugs because this market takes on both market structures. When a firm discovers a new drug, patent laws give the firm a monopoly on the sale of that drug. But eventually the firm's patent runs out, and any company can make and sell the drug. At that time, the market switches from being...

Case Study Rent Control In The Short Run And Long

Partial Rent Control Quantities

One common example of a price ceiling is rent control. In some cities, the local government places a ceiling on rents that landlords may charge their tenants. The goal of this policy is to help the poor by making housing more affordable. Economists often criticize rent control, arguing that it is a highly inefficient way to help the poor raise their standard of living. One economist called rent control the best way to destroy a city, other than bombing. The adverse effects of rent control are...

Externalities In Consumption

Positive Consumption

The externalities we have discussed so far are associated with the production of goods. Some externalities, however, are associated with consumption. The consumption of alcohol, for instance, yields negative externalities if consumers are more likely to drive under its influence and risk the lives of others. Similarly, the consumption of education yields positive externalities because a more educated population leads to better government, which benefits everyone. The analysis of consumption...

Case Study Are Lighthouses Public Goods

Lighthouses Free

Some goods can switch between being public goods and being private goods depending on the circumstances. For example, a fireworks display is a public good if performed in a town with many residents. Yet if performed at a private amusement park, such as Walt Disney World, a fireworks display is more like a private good because visitors to the park pay for admission. Another example is a lighthouse. Economists have long used lighthouses as examples of a public good. Lighthouses are used to mark...

Most economic models, unlike the circular-flow diagram, are built using the tools of mathematics. Here we consider one of the simplest such models, called the production possibilities frontier, and see how this model illustrates some basic economic ideas. Although real economies produce thousands of goods and services, let's imagine an economy that produces only two goods cars and computers. Together the car industry and the computer industry use all of the economy's factors of production. The...
