What Is Economics?

To appreciate how a business functions, we need to know something about the economic environment in which it operates. We begin with a definition of economics and a discussion of the resources used to produce goods and services.

EconomicseconomicsStudy of how scarce resources are used to produce outputs—goods and services—that are distributed among people. is the study of how scarce resources are used to produce outputs—goods and services—to be distributed among people. ResourcesresourcesInputs used to produce outputs. are the inputs used to produce outputs. Resources may include any or all of the following:

  • Land and other natural resources

  • Labor (physical and mental)

  • Capital, including buildings, equipment, and money

  • Entrepreneurship

Resources are combined to produce goods and services. Land and natural resources provide the needed raw materials. Labor transforms raw materials into goods and services. Capital (equipment, buildings, vehicles, cash, and so forth) are needed for the production process. Entrepreneurship provides the skill and creativity needed to bring the other resources together to capitalize on an idea.

Because a business uses resources to produce things, we also call these resources factors of productionfactors of productionResources consisting of land, labor, capital (money, buildings, equipment), and entrepreneurial skills combined to produce goods and services.. The factors of production used to produce a shirt would include the following:

  • The land that the shirt factory sits on, the electricity used to run the plant, and the raw cotton from which the shirts are made

  • The laborers who make the shirts

  • The factory and equipment used in the manufacturing process, as well as the money needed to operate the factory

  • The entrepreneurship skill used to coordinate the other resources to initiate the production process

The answers to these questions depend on a country’s economic systemeconomic systemMeans by which a society makes decisions about allocating resources to produce and distribute products.—the means by which a society (households, businesses, and government) makes decisions about allocating resources to produce products and about distributing those products. The degree to which individuals and business owners, as opposed to the government, enjoy freedom in making these decisions varies according to the type of economic system. Generally speaking, economic systems can be divided into two systems: planned systems and free market systems.

In a planned system, the government exerts control over the allocation and distribution of all or some goods and services. The system with the highest level of government control is communismcommunismEconomic system featuring the highest level of government control over allocation and distribution.. In theory, a communist economy is one in which the government owns all or most enterprises. Central planning by the government dictates which goods or services are produced, how they are produced, and who will receive them. In practice, pure communism is practically nonexistent today, and only a few countries (notably North Korea and Cuba) operate under rigid, centrally planned economic systems.

Under socialismsocialismEconomic system falling between communism and capitalism in terms of government control over allocation and distribution., industries that provide essential services, such as utilities, banking, and health care, may be government owned. Other businesses are owned privately. Central planning allocates the goods and services produced by government-run industries and tries to ensure that the resulting wealth is distributed equally. In contrast, privately owned companies are operated for the purpose of making a profit for their owners. In general, workers in socialist economies work fewer hours, have longer vacations, and receive more health, education, and child-care benefits than do workers in capitalist economies. To offset the high cost of public services, taxes are generally steep. Examples of socialist countries include Sweden and France.

In comparing economic systems, it’s helpful to think of a continuum with communism at one end and pure capitalism at the other, as in Figure 1.5, “The Spectrum of Economic Systems”. As you move from left to right, the amount of government control over business diminishes. So, too, does the level of social services, such as health care, child-care services, social security, and unemployment benefits.

The Spectrum of Economic Systems

Like most countries, the United States features a mixed market system: though the U.S. economic system is primarily a free market system, the federal government controls some basic services, such as the postal service and air traffic control. The U.S. economy also has some characteristics of a socialist system, such as providing social security retirement benefits to retired workers.

The free market system was espoused by Adam Smith in his book The Wealth of Nations, published in 1776.[11] According to Smith, competition alone would ensure that consumers received the best products at the best prices. In the kind of competition he assumed, a seller who tries to charge more for his product than other sellers won’t be able to find any buyers. A job-seeker who asks more than the going wage won’t be hired. Because the “invisible hand” of competition will make the market work effectively, there won’t be a need to regulate prices or wages.

Almost immediately, however, a tension developed among free market theorists between the principle of laissez-faire—leaving things alone—and government intervention. Today, it’s common for the U.S. government to intervene in the operation of the economic system. For example, government exerts influence on the food and pharmaceutical industries through the Food and Drug Administration, which protects consumers by preventing unsafe or mislabeled products from reaching the market.

To appreciate how businesses operate, we must first get an idea of how prices are set in competitive markets. Thus, the next section begins by describing how markets establish prices in an environment of perfect competition.
