You have to make the right number of CD players for people to use. If you make too many CDs and not enough cassette tapes, people with cassette players will be stuck with CDs they cannot play.

You will also be faced with tough choices about the music industry compared to other parts of the economy. If you produce more sports equipment, you will have fewer resources for making CDs.

So all decisions about the economy influence your decisions about CD production. Countries that have corrupt police and court systems do not enforce individual property rights, including the rights over the goods and services produced by households and firms. Firms will not choose to produce products and individuals will choose not to work if there is no guarantee that they will receive payment for their efforts.

Therefore, these countries end up with a lower standard of living. Efficiency: The market failure comes from the market power of the cable TV firm. Equity c.

Efficiency: There is an externality because of accidents caused by drunk drivers. If everyone were guaranteed the best health care possible, much more of our nation's output would be devoted to medical care than is now the case. Would that be efficient?

If you believe that doctors have market power and restrict health care to keep their incomes high, you might think efficiency would increase by providing more health care. PMG But more likely, if the government mandated increased spending on health care, the economy would be less efficient because it would give people more health care than they would choose to pay for.

From the point of view of equity, if poor people are less likely to have adequate health care, providing more health care would represent an improvement. Each person would have a more even slice of the economic pie, though the pie would consist of more health care and less of other goods. When workers are laid off, equity considerations argue for the unemployment benefits system to provide them with some income until they can find new jobs.

After all, no one plans to be laid off, so unemployment benefits are a form of insurance. The economy is not operating efficiently if people remain unemployed for a long time, and unemployment benefits encourage unemployment. Thus, there is a trade-off between equity and efficiency.


The more generous unemployment benefits are, the less income is lost by an unemployed person, but the more that person is encouraged to remain unemployed. So greater equity reduces efficiency. Because average income in the United States has roughly doubled every 35 years, we are likely to have a better standard of living than our parents, and a much better standard of living than our grandparents.

This is mainly the result of increased productivity, so that an hour of work produces more goods and services than it used to.

Thus, incomes have continuously risen over time, as has the standard of living. If Americans save more and it leads to more spending on factories, there will be an increase in production and productivity, because the same number of workers will have more equipment to work with. The benefits from higher productivity will go to both the workers, who will get paid more because they are producing more, and the factory owners, who will get a return on their investments. There is no such thing as a free lunch, however, because when people save more, they are giving up spending.

They get higher incomes at the cost of buying fewer goods.


To make an intelligent decision about whether to reduce inflation, a policymaker would need to know what causes inflation and unemployment, as well as what determines the trade-off between them. This means that the policymaker needs to understand how households and firms will adjust to a decrease in the money supply. How much will spending decline? How much will firms lower output? Any attempt to reduce inflation will likely lead to higher unemployment in the short run. A policymaker thus faces a trade-off between the benefits of lower inflation compared to the cost of higher unemployment.

Answers will vary. Chapter 1 introduced ten principles of economics that will be revisited throughout the text. Chapter 2 develops how economists approach problems while Chapter 3 will explain how individuals and countries gain from trade. The purpose of Chapter 2 is to familiarize students with how economists approach economic problems. With practice, they will learn how to approach similar problems in this dispassionate systematic way. They will see how economists employ the scientific method, the role of assumptions in model building, and the application of two specific economic models.

Students will also learn the important distinction between two roles economists can play: as scientists when we try to explain the economic world and as policymakers when we try to improve it.

Like all scientists, they make appropriate assumptions and build simplified models in order to understand the world around them. Two simple economic models are the circular-flow diagram and the production possibilities frontier. The field of economics is divided into two subfields: microeconomics and macroeconomics. Microeconomists study decisionmaking by households and firms and the interaction among households and firms in the marketplace. Macroeconomists study the forces and trends that affect the economy as a whole.

A positive statement is an assertion about how the world is. A normative statement is an assertion about how the world ought to be. When economists make normative statements, they are acting more as policy advisers than scientists. Economists who advise policymakers offer conflicting advice either because of differences in scientific judgments or because of differences in values. At other times, economists are united in the advice they offer, but policymakers may choose to ignore it.

The Economist as Scientist A. Economists follow the scientific method. Observations help us to develop theory. Data can be collected and analyzed to evaluate theories. Using data to evaluate theories is more difficult in economics than in physical science because economists are unable to generate their own data and must make do with whatever data are available. Thus, economists pay close attention to the natural experiments offered by history.
