Suppose you were assigned to compile a list of all the individual goods and services there, including the different brands and variations of each type of product. That task would be daunting and the list would be long! And even though a single shopping mall contains a remarkable quantity and variety of goods, it is only a tiny part of the national economy. Who decided that the particular goods and services available at the mall and in the broader economy should be produced? How did the producers determine which technology and types of resources to use in producing these particular goods? Who will obtain these products? What accounts for the new and improved products among these goods? This chapter will answer these and related questions. 29 McConnell-Brue-Flynn: Microeconomics: Principles, Problems, and Policies, 18th Edition I. Introduction to Economics and the Economy 2. The Market System and the Circular Flow The McGraw-Hill Companies, 2009 30 PART ONE Introduction to Economics and the Economy Economic Systems Every society needs to develop an economic system--a particular set of institutional arrangements and a coordinating mechanism--to respond to the economizing problem. The economic system has to determine what goods are produced, how they are produced, who gets them, how to accommodate change, and how to promote technological progress. Economic systems differ as to (1) who owns the factors of production and (2) the method used to motivate, coordinate, and direct economic activity. Economic systems have two polar extremes: the command system and the market system. The Market System The polar alternative to the command system is the market system, or capitalism. The system is characterized by the private ownership of resources and the use of markets and prices to coordinate and direct economic activity. Participants act in their own self-interest. Individuals and businesses seek to achieve their economic goals through their own decisions regarding work, consumption, or production. The system allows for the private ownership of capital, communicates through prices, and coordinates economic activity through markets--places where buyers and sellers come together. Goods and services are produced and resources are supplied by whoever is willing and able to do so. The result is competition among independently acting buyers and sellers of each product and resource. Thus, economic decision making is widely dispersed. Also, the high potential monetary rewards create powerful incentives for existing firms to innovate and entrepreneurs to pioneer new products and processes. In pure capitalism--or laissez-faire capitalism-- government's role would be limited to protecting private property and establishing ORIGIN OF THE IDEA an environment appropriate to the operation of O 2.1 the market system. The Laissez-faire term "laissez-faire" means "let it be," that is, keep government from interfering with the economy. The idea is that such interference will disturb the efficient working of the market system. But in the capitalism practiced in the United States and most other countries, government plays a substantial role in the economy. It not only provides the rules for economic activity but also promotes economic stability and growth, provides certain goods and services that would otherwise be underproduced or not produced at all, and modifies the distribution of income. The government, however, is not the dominant economic force in deciding what to produce, how to produce it, and who will get it. That force is the market. The Command System The command system is also known as socialism or communism. In that system, government owns most property resources and economic decision making occurs through a central economic plan. A central planning board appointed by the government makes nearly all the major decisions concerning the use of resources, the composition and distribution of output, and the organization of production. The government owns most of the business firms, which produce according to government directives. The central planning board determines production goals for each enterprise and specifies the amount of resources to be allocated to each enterprise so that it can reach its production goals. The division of output between capital and consumer goods is centrally decided, and capital goods are allocated among industries on the basis of the central planning board's long-term priorities. A pure command economy would rely exclusively on a central plan to allocate the government-owned property resources. But, in reality, even the preeminent command economy--the Soviet Union--tolerated some private ownership and incorporated some markets before its collapse in 1992. Recent reforms in Russia and most of the eastern European nations have to one degree or another transformed their command economies to capitalistic, marketoriented systems. China's reforms have not gone as far, but they have greatly reduced the reliance on central planning. Although government ownership of resources and capital in China is still extensive, the nation has increasingly relied on free markets to organize and coordinate its economy. North Korea and Cuba are the last prominent remaining examples of largely centrally planned economies. Other countries using mainly the command system include Turkmenistan, Laos, Belarus, Libya, Myanmar, and Iran. Later in this chapter, we will explore the main reasons for the general demise of the command systems. Characteristics of the Market System An examination of some of the key features of the market system in detail will be very instructive. Private Property In a market system, private individuals and firms, not the government, own most of the property resources (land and capital). It is this extensive private ownership of capital McConnell-Brue-Flynn: Microeconomics: Principles, Problems, and Policies, 18th Edition I. Introduction to Economics and the Economy 2. The Market System and the Circular Flow The McGraw-Hill Companies, 2009 CHAPTER 2 31 The Market System and the Circular Flow that gives capitalism its name. This right of private property, coupled with the freedom to negotiate binding legal contracts, enables individuals and businesses to obtain, use, and dispose of property resources as they see fit. The right of property owners to designate who will receive their property when they die helps sustain the institution of private property. Property rights encourage investment, innovation, exchange, maintenance of property, and economic growth. Nobody would stock a store, build a factory, or clear land for farming if someone else, or the government itself, could take that property for his or her own benefit. Property rights also extend to intellectual property through patents, copyrights, and trademarks. Such longterm protection encourages people to write books, music, and computer programs and to invent new products and production processes without fear that others will steal them and the rewards they may bring. Moreover, property rights facilitate exchange. The title to an automobile or the deed to a cattle ranch assures the buyer that the seller is the legitimate owner. Also, property rights encourage owners to maintain or improve their property so as to preserve or increase its value. Finally, property rights enable people to use their time and resources to produce more goods and services, rather than using them to protect and retain the property they have already produced or acquired. Self-Interest In the market system, self-interest is the motivating force of the various economic units as they express their free choices. Self-interest simply means that each economic unit tries to achieve its ORIGIN OF THE IDEA own particular goal, which usually requires O 2.2 delivering something of Self-interest value to others. Entrepreneurs try to maximize profit or minimize loss. Property owners try to get the highest price for the sale or rent of their resources. Workers try to maximize their utility (satisfaction) by finding jobs that offer the best combination of wages, hours, fringe benefits, and working conditions. Consumers try to obtain the products they want at the GLOBAL PERSPECTIVE 2.1 Index of Economic Freedom, Selected Economies The Index of Economic Freedom measures economic freedom using 10 broad categories such as trade policy, property rights, and government intervention, with each category containing more than 50 specific criteria. The index then ranks 157 economies according to their degree of economic freedom. A few selected rankings for 2008 are listed below.

Freedom of Enterprise and Choice Closely related to private ownership of property is freedom of enterprise and choice. The market system requires that various economic units make certain choices, which are expressed and implemented in the economy's markets: Freedom of enterprise ensures that entrepreneurs and private businesses are free to obtain and use economic resources to produce their choice of goods and services and to sell them in their chosen markets. Freedom of choice enables owners to employ or dispose of their property and money as they see fit. It also allows workers to try to enter any line of work for which they are qualified. Finally, it ensures that consumers are free to buy the goods and services that best satisfy their wants and that their budgets allow. These choices are free only within broad legal limitations, of course. Illegal choices such as selling human organs or buying illicit drugs are punished through fines and imprisonment. (Global Perspective 2.1 reveals that the degree of economic freedom varies greatly from economy to economy.) McConnell-Brue-Flynn: Microeconomics: Principles, Problems, and Policies, 18th Edition I. Introduction to Economics and the Economy 2. The Market System and the Circular Flow The McGraw-Hill Companies, 2009 32 PART ONE Introduction to Economics and the Economy lowest possible price and apportion their expenditures to maximize their utility. The motive of self-interest gives direction and consistency to what might otherwise be a chaotic economy. Competition The market system depends on competition among economic units. The basis of this competition is freedom of choice exercised in pursuit of a monetary return. Very broadly defined, competition requires Two or more buyers and two or more sellers acting independently in a particular product or resource market. (Usually there are many more than two buyers or sellers.) Freedom of sellers and buyers to enter or leave markets, on the basis of their economic self-interest. Competition among buyers and sellers diffuses economic power within the businesses and households that make up the economy. When there are many buyers and sellers acting independently in a market, no single buyer or seller can dictate the price of the product or resource because others can undercut that price. Competition also implies that producers can enter or leave an industry; no insurmountable barriers prevent an industry's expanding or contracting. This freedom of an industry to expand or contract provides the economy with the flexibility needed to remain efficient over time. Freedom of entry and exit enables the economy to adjust to changes in consumer tastes, technology, and resource availability. The diffusion of economic power inherent in competition limits the potential abuse of that power. A producer that charges more than the competitive market price will lose sales to other producers. An employer who pays less than the competitive market wage rate will lose workers to other employers. A firm that fails to exploit new technology will lose profits to firms that do. Competition is the basic regulatory force in the market system. is an institution or mechanism that brings buyers ("demanders") and sellers ("suppliers") into contact. A market system conveys the decisions made by buyers and sellers of products and resources. The decisions made on each side of the market determine a set of product and resource prices that guide resource owners, entrepreneurs, and consumers as they make and revise their choices and pursue their self-interest. Just as competition is the regulatory mechanism of the market system, the market system itself is the organizing and coordinating mechanism. It is an elaborate communication network through which innumerable individual free choices are recorded, summarized, and balanced. Those who respond to market signals and heed market dictates are rewarded with greater profit and income; those who do not respond to those signals and choose to ignore market dictates are penalized. Through this mechanism society decides what the economy should produce, how production can be organized efficiently, and how the fruits of production are to be distributed among the various units that make up the economy. QUICK REVIEW 2.1 The market system rests on the private ownership of property and on freedom of enterprise and freedom of choice. The market system permits consumers, resource suppliers, and businesses to pursue and further their self-interest. Competition diffuses economic power and limits the actions of any single seller or buyer. The coordinating mechanism of capitalism is a system of markets and prices. Technology and Capital Goods In the market system, competition, freedom of choice, selfinterest, and personal reward provide the opportunity and motivation for technological advance. The monetary rewards for new products or production techniques accrue directly to the innovator. The market system therefore encourages extensive use and rapid development of complex capital goods: tools, machinery, large-scale factories, and facilities for storage, communication, transportation, and marketing. Advanced technology and capital goods are important because the most direct methods of production are often the least efficient. The only way to avoid that inefficiency is to rely on capital goods. It would be ridiculous for a farmer to go at production with bare hands. There are huge benefits to be derived from creating and using such capital equipment as plows, tractors, and storage bins. The more efficient production means much more abundant output. Markets and Prices We may wonder why an economy based on self-interest does not collapse in chaos. If consumers want breakfast cereal but businesses choose to produce running shoes and resource suppliers decide to make computer software, production would seem to be deadlocked by the apparent inconsistencies of free choices. In reality, the millions of decisions made by households and businesses are highly coordinated with one another by markets and prices, which are key components of the market system. They give the system its ability to coordinate millions of daily economic decisions. A market McConnell-Brue-Flynn: Microeconomics: Principles, Problems, and Policies, 18th Edition I. Introduction to Economics and the Economy 2. The Market System and the Circular Flow The McGraw-Hill Companies, 2009 CHAPTER 2 33 The Market System and the Circular Flow Specialization The extent to which market economies rely on specialization is extraordinary. Specialization is the use of resources of an individual, firm, region, or nation to produce one or a few goods or services rather than the entire range of goods and services. Those goods and services are then exchanged for a full range of desired products. The majority of consumers produce virtually none of the goods and services they consume, and they consume little or nothing of the items they produce. The person working nine to five installing windows in commercial aircraft may rarely fly. Many farmers sell their milk to the local dairy and then buy margarine at the local grocery store. Society learned long ago that self-sufficiency breeds inefficiency. The jack-of-all-trades may be a very colorful individual but is certainly not an efficient producer. Human specialization--called the division of labor--contributes to a society's output in several ways: Specialization makes use of differences in ability. Specialization enables individuals to take advantage of existing differences in their abilities and skills. If Peyton is strong, athletic, and good at throwing a football and Beyonce is ORIGIN OF THE IDEA beautiful, agile, and can sing, their distribution O 2.3 of talents can be most Specialization: division of labor efficiently used if Peyton plays professional football and Beyonce records songs and gives concerts. Specialization fosters learning by doing. Even if the abilities of two people are identical, specialization may still be advantageous. By devoting time to a single task, a person is more likely to develop the skills required and to improve techniques than by working at a number of different tasks. You learn to be a good lawyer by studying and practicing law. Specialization saves time. By devoting time to a single task, a person avoids the loss of time incurred in shifting from one job to another. Also, time is saved by not "fumbling around" with a task that one is not trained to do. For all these reasons, specialization increases the total output society derives from limited resources. that wheat could be grown in Florida, but such production would be costly for similar geographical reasons. So Nebraskans produce products--wheat in particular--for which their resources are best suited, and Floridians do the same, producing oranges and other citrus fruits. By specializing, both economies produce more than is needed locally. Then, very sensibly, Nebraskans and Floridians swap some of their surpluses--wheat for oranges, oranges for wheat. Similarly, on an international scale, the United States specializes in producing such items as commercial aircraft and computers, which it sells abroad in exchange for video recorders from Japan, bananas from Honduras, and woven baskets from Thailand. Both human specialization and geographic specialization are needed to achieve efficiency in the use of limited resources. Division of Labor Use of Money A rather obvious characteristic of any economic system is the extensive use of money. Money performs several functions, but first and foremost it is a medium of exchange. It makes trade easier. Specialization requires exchange. Exchange can, and sometimes does, occur through barter--swapping goods for goods, say, wheat for oranges. But barter poses serious problems because it requires a coincidence of wants between the buyer and the seller. In our example, we assumed that Nebraskans had excess wheat to trade and wanted oranges. And we assumed that Floridians had excess oranges to trade and wanted wheat. So an exchange occurred. But if such a coincidence of wants is missing, trade is stymied. Suppose that Nebraska has no interest in Florida's oranges but wants potatoes from Idaho. And suppose that Idaho wants Florida's oranges but not Nebraska's wheat. And, to complicate matters, suppose that Florida wants some of Nebraska's wheat but none of Idaho's potatoes. We summarize the situation in Figure 2.1. In none of the cases shown in the figure is there a coincidence of wants. Trade by barter clearly would be difficult. Instead, people in each state use money, which is simply a convenient social invention to facilitate exchanges of goods and services. Historically, people have used cattle, cigarettes, shells, stones, pieces of metal, and many other commodities, with varying degrees of success, as a medium of exchange. But to serve as money, an item needs to pass only one test: It must be generally acceptable to sellers in exchange for their goods and services. Money is socially defined; whatever society accepts as a medium of exchange is money. Today, most economies use pieces of paper as money. The use of paper dollars (currency) as a medium of exchange is what enables Nebraska, Florida, and Idaho to overcome their trade stalemate, as demonstrated in Figure 2.1. Geographic Specialization Specialization also works on a regional and international basis. It is conceivable that oranges could be grown in Nebraska, but because of the unsuitability of the land, rainfall, and temperature, the costs would be very high. And it is conceivable McConnell-Brue-Flynn: Microeconomics: Principles, Problems, and Policies, 18th Edition I. Introduction to Economics and the Economy 2. The Market System and the Circular Flow The McGraw-Hill Companies, 2009 34 PART ONE Introduction to Economics and the Economy FIGURE 2.1 Money facilitates trade when wants do not coincide. The use of money as a medium of exchange permits trade to be accomplished despite a noncoincidence of wants. (1) Nebraska trades the wheat that Florida wants for money from Floridians; (2) Nebraska trades the money it receives from Florida for the potatoes it wants from Idaho; (3) Idaho trades the money it receives from Nebraska for the oranges it wants from Florida. (1 ) M on ey NEBRASKA Has surplus of wheat. Wants potatoes. (2 he at ) (2 ) M on ey t Po (1 )W at oe s FLORIDA Has surplus of oranges. Wants wheat. (3) Oranges (3) Money IDAHO Has surplus of potatoes. Wants oranges. On a global basis different nations have different currencies, and that complicates specialization and exchange. But markets in which currencies are bought and sold make it possible for U.S. residents, Japanese, Germans, Britons, and Mexicans, through the swapping of dollars, yen, euros, pounds, and pesos, one for another, to exchange goods and service without resorting to barter. Five Fundamental Questions The key features of the market system help explain how market economies respond to five fundamental questions: What goods and services will be produced? How will the goods and services be produced? Who will get the goods and services? How will the system accommodate change? How will the system promote progress? These five questions highlight the economic choices underlying the production possibilities curve discussed in Chapter 1. They reflect the reality of scarce resources in a world of unlimited wants. All economies, whether market or command, must address these five questions. Active, but Limited, Government An active, but limited, government is the final characteristic of market systems in modern advanced industrial economies. Although a market system promotes a high degree of efficiency in the use of its resources, it has certain inherent shortcomings, called "market failures." We will discover in subsequent chapters that government can increase the overall effectiveness of the economic system in several ways. What Will Be Produced? How will a market system decide on the specific types and quantities of goods to be produced? The simple answer is this: The goods and services produced at a continuing profit will be produced, and those produced at a continuing loss will not. Profits and losses are the difference between the total revenue (TR) a firm receives from the sale of its products and the total opportunity cost (TC) of producing those products. (For economists, economic costs include not only wage and salary payments to labor, and interest and rental payments for capital and land, but also payments to the entrepreneur for organizing and combining the other resources to produce a commodity.) Continuing economic profit (TR TC) in an industry results in expanded production and the movement of QUICK REVIEW 2.2 The market systems of modern industrial economies are characterized by extensive use of technologically advanced capital goods. Such goods help these economies achieve greater efficiency in production. Specialization is extensive in market systems; it enhances efficiency and output by enabling individuals, regions, and nations to produce the goods and services for which their resources are best suited. The use of money in market systems facilitates the exchange of goods and services that specialization requires.

The Market System and the Circular Flow The McGraw-Hill Companies, 2009 CHAPTER 2 35 The Market System and the Circular Flow resources toward that industry. Existing firms grow and new firms enter. The industry expands. Continuing losses (TC TR) in an industry leads to reduced production and the exit of resources from that industry. Some existing firms shrink in size; others go out of business. The industry contracts. In the market system, consumers are sovereign (in command). Consumer sovereignty is crucial in determining the types and quantities of goods produced. Consumers spend their income on the goods they are most willing and able to buy. Through these "dollar votes" they register their wants in the market. If the dollar votes for a certain product are great enough to create a profit, businesses will produce that product and offer it for sale. In contrast, if the dollar votes do not create sufficient revenues to cover costs, businesses will not produce the product. So the consumers are sovereign. They collectively direct resources to indus- CONSIDER THIS . . . McHits and McMisses McDonald's has introduced several new menu items over the decades. Some have been profitable "hits," while others have been "misses." Ultimately, consumers decide whether a menu item is profitable and therefore whether it stays on the McDonald's menu. tries that are meeting consumer wants and away from industries that are not meeting consumer wants. The dollar votes of consumers determine not only which industries will continue to exist but also which products will survive or fail. Only profitable industries, firms, and products survive. So firms are not as free to produce whatever products they wish as one might otherwise think. Consumers' buying decisions make the production of some products profitable and the production of other products unprofitable, thus restricting the choice of businesses in deciding what to produce. Businesses must match their production choices with consumer choices or else face losses and eventual bankruptcy. The same holds true for resource suppliers. The employment of resources derives from the sale of the goods and services that the resources help produce. Autoworkers are employed because automobiles are sold. There are few remaining professors of early Latin because there are few people desiring to learn the Latin language. Resource suppliers, desiring to earn income, are not truly free to allocate their resources to the production of goods that consumers do not value highly. Consumers register their preferences in the market; producers and resource suppliers, prompted by their own self-interest, respond appropriately. (Key Question 8) How Will the Goods and Services Be Produced? What combinations of resources and technologies will be used to produce goods and services? How will the production be organized? The answer: In combinations and ways that minimize the cost per unit of output. Because competition eliminates high-cost producers, profitability requires that firms produce their output at minimum cost per unit. Achieving this least-cost production necessitates, for example, that firms use the right mix of labor and capital, given the prices and productivity of those resources. It also means locating production facilities optimally to hold down production and transportation expenses. Least-cost production also means that firms must employ the most economically efficient technique of production in producing their output. The most efficient production technique depends on The available technology, that is, the various combinations of resources that will produce the desired results. The prices of the needed resources. A technique that requires just a few inputs of resources to produce a specific output may be highly inefficient economically if those resources are valued very highly in the Hulaburger (1962)--McMiss Filet-O-Fish (1963)--McHit Strawberry shortcake (1966)--McMiss Big Mac (1968)--McHit Hot apple pie (1968)--McHit Egg McMuffin (1975)--McHit Drive-thru (1975)--McHit Chicken McNuggets (1983)--McHit Extra Value Meal (1991)--McHit McLean Deluxe (1991)--McMiss Arch Deluxe (1996)--McMiss 55-cent special (1997)--McMiss Big Xtra (1999)--McHit Source: "Polishing the Golden Arches," Forbes, June 15, 1998, pp. 4243, updated.

The Market System and the Circular Flow The McGraw-Hill Companies, 2009 36 PART ONE Introduction to Economics and the Economy TABLE 2.1 Three Techniques for Producing $15 Worth of Bar Soap Units of Resource Resource Price per Unit of Resource $2 1 3 3 Technique 1 Units 4 1 1 1 Cost $ 8 1 3 3 $15 Technique 2 Units 2 3 1 1 Cost $ 4 3 3 3 $13 Technique 3 Units 1 4 2 1 Cost $ 2 4 6 3 $15 Labor Land Capital Entrepreneurial ability Total cost of $15 worth of bar soap market. Economic efficiency requires obtaining a particular output of product with the least input of scarce resources, when both output and resource inputs are measured in dollars and cents. The combination of resources that will produce, say, $15 worth of bathroom soap at the lowest possible cost is the most efficient. Suppose there are three possible techniques for producing the desired $15 worth of bars of soap. Suppose also that the quantity of each resource required by each production technique and the prices of the required resources are as shown in Table 2.1. By multiplying the required quantities of each resource by its price in each of the three techniques, we can determine the total cost of producing $15 worth of soap by means of each technique. Technique 2 is economically the most efficient, because it is the least costly. It enables society to obtain $15 worth of output by using a smaller WORKED PROBLEMS amount of resources-- $13 worth--than the $15 W 2.1 worth required by the Least-cost production two other techniques. Competition will dictate that producers use technique 2. Thus, the question of how goods will be produced is answered. They will be produced in a least-cost way. A change in either technology or resource prices, however, may cause a firm to shift from the technology it is using. If the price of labor falls to $.50, technique 1 becomes more desirable than technique 2. Firms will find they can lower their costs by shifting to a technology that uses more of the resource whose price has fallen. Exercise: Would a new technique involving 1 unit of labor, 4 of land, 1 of capital, and 1 of entrepreneurial ability be preferable to the techniques listed in Table 2.1, assuming the resource prices shown there? (Key Question 9) their ability and willingness to pay its existing market price. If the price of some product, say, a small sailboat, is $3000, then buyers who are willing and able to pay that price will "sail, sail away." Consumers who are unwilling or unable to pay the price will be "sitting on the dock of the bay." The ability to pay the prices for sailboats and other products depends on the amount of income that consumers have, along with the prices of, and preferences for, various goods. If consumers have sufficient income and want to spend their money on a particular good, they can have it. And the amount of income they have depends on (1) the quantities of the property and human resources they supply and (2) the prices those resources command in the resource market. Resource prices (wages, interest, rent, profit) are crucial in determining the size of each person's income and therefore each person's ability to buy part of the economy's output. If a lawyer earning $200 an hour and a recreational worker earning $10 an hour both work the same number of hours each year, the lawyer will be able to take possession of 20 times as much of society's output as the recreational worker that year. How Will the System Accommodate Change? Market systems are dynamic: Consumer preferences, technology, and supplies of resources all change. This means that the particular allocation of resources that is now the most efficient for a specific pattern of consumer tastes, range of technological alternatives, and amount of available resources will become obsolete and inefficient as consumer preferences change, new techniques of production are discovered, and resource supplies change over time. Can the market economy adjust to such changes? Suppose consumer tastes change. For instance, assume that consumers decide they want more fruit juice and less milk than the economy currently provides. Those changes in consumer tastes will be communicated to producers through an increase in spending on fruit and a decline in Who Will Get the Output? The market system enters the picture in two ways when determining the distribution of total output. Generally, any product will be distributed to consumers on the basis of McConnell-Brue-Flynn: Microeconomics: Principles, Problems, and Policies, 18th Edition I. Introduction Economics to and the Economy 2. The Market System and the Circular Flow The McGraw-Hill Companies, 2009 CHAPTER 2 37 The Market System and the Circular Flow spending on milk. Other things equal, prices and profits in the fruit juice industry will rise and those in the milk industry will fall. Self-interest will induce existing competitors to expand output and entice new competitors to enter the prosperous fruit industry and will in time force firms to scale down--or even exit--the depressed milk industry. The higher prices and greater economic profit in the fruit-juice industry will not only induce that industry to expand but will also give it the revenue needed to obtain the resources essential to its growth. Higher prices and profits will permit fruit producers to attract more resources from less urgent alternative uses. The reverse occurs in the milk industry, where fewer workers and other resources are employed. These adjustments in the economy are appropriate responses to the changes in consumer tastes. This is consumer sovereignty at work. The market system is a gigantic communications system. Through changes in prices and profits, it communicates changes in such basic matters as consumer tastes and elicits appropriate responses from businesses and resource suppliers. By affecting price and profits, changes in consumer tastes direct the expansion of some industries and the contraction of others. Those adjustments are conveyed to the resource market. As expanding industries employ more resources and contracting industries employ fewer, the resulting changes in resource prices (wages and salaries, for example) and income flows guide resources from the contracting industries to the expanding industries. This directing or guiding function of prices and profits is a core element of the market system. Without such a system, a government planning board or some other administrative agency would have to direct businesses and resources into the appropriate industries. A similar analysis shows that the system can and does adjust to other fundamental changes--for example, to changes in technology and in the prices of various resources. expense of rivals. Firms that are highly profitable one year may find they are in financial trouble just a few years later. Technological advance also includes new and improved methods that reduce production or distribution costs. By passing part of its cost reduction on to the consumer through a lower product price, a firm can increase sales and obtain economic profit at the expense of rival firms. Moreover, the market system promotes the rapid spread of technological advance throughout an industry. Rival firms must follow the lead of the most innovative firm or else suffer immediate losses and eventual failure. In some cases, the result is creative destruction: The creation of new products and production methods completely destroys the market positions of firms that are wedded to existing products and older ways of doing business. Example: The advent of compact discs largely demolished long-play vinyl records, and iPods and other digital technologies are now supplanting CDs. Capital Accumulation Most technological advances require additional capital goods. The market system provides the resources necessary to produce those goods through increased dollar votes for capital goods. That is, the market system acknowledges dollar voting for capital goods as well as for consumer goods. But who will register votes for capital goods? Answer: Entrepreneurs and owners of businesses. As receivers of profit income, they often use part of that income to purchase capital goods. Doing so yields even greater profit income in the future if the technological innovation is successful. Also, by paying interest or selling ownership shares, the entrepreneur and firm can attract some of the income of households as saving to increase their dollar votes for the production of more capital goods. (Key Question 10) QUICK REVIEW 2.3 The output mix of the market system is determined by profits, which in turn depend heavily on consumer preferences. Economic profits cause industries to expand; losses cause industries to contract. Competition forces industries to use the least costly production methods. Competitive markets reallocate resources in response to changes in consumer tastes, technological advances, and changes in availability of resources. In a market economy, consumer income and product prices determine how output will be distributed. Competitive markets create incentives for technological advance and capital accumulation, both of which contribute to increases in standards of living. How Will the System Promote Progress? Society desires economic growth (greater output) and higher standards of living (greater income per person). How does the market system promote technological improvements and capital accumulation, both of which contribute to a higher standard of living for society? Technological Advance The market system provides a strong incentive for technological advance and enables better products and processes to supplant inferior ones.

Introduction to Economics and the Economy 2. The Market System and the Circular Flow The McGraw-Hill Companies, 2009 38 PART ONE Introduction to Economics and the Economy The "Invisible Hand" In his 1776 book The Wealth of Nations, Adam Smith first noted that the operation of a market system creates a curious unity between private interests and social interests. Firms and resource suppliers, seeking to further their own self-interest and operating within the framework of a highly competitive market system, will simultaneously, as though guided by an "invisible hand," promote the public or social interest. For example, we have seen that in a competitive environment, businesses seek to build new and improved products to increase profits. Those enhanced products increase society's well-being. Businesses also use the least costly combination of resources to produce a specific output because doing so is in their selfinterest. To act otherwise would be to forgo profit or even to risk business failure. But, at the same time, to use scarce resources in the least costly way is clearly in the social interest as well. It "frees up" resources to produce something else that society desires. Self-interest, awakened and guided by the competitive market system, is what induces responses appropriate to the changes in society's wants. Businesses seeking to make higher profits and to avoid losses, and resource suppliers pursuing greater monetary rewards, negotiate changes in the allocation of resources and end up with the output that society wants. Competition controls or guides self-interest such that self-interest automatically and quite unintentionally furthers the best interest of society. The invisible hand ensures that when firms maximize their profits and resource suppliers maximize their incomes, these groups also help maximize society's output and income. Of the various virtues of the market system, three merit reemphasis: Efficiency The market system promotes the efficient use of resources by guiding them into the production of the goods and services most wanted by society. It forces the use of the most efficient techniques in organizing resources for production, and it encourages the development and adoption of new and more efficient production techniques. Incentives The market system encourages skill acquisition, hard work, and innovation. Greater work skills and effort mean greater production and higher incomes, which usually translate into a higher standard of living. Similarly, the assuming of risks by entrepreneurs can result in substantial profit incomes. Successful innovations generate economic rewards. Freedom The major noneconomic argument for the market system is its emphasis on personal freedom. In contrast to central planning, the market system coordinates economic activity without coercion. The market system permits--indeed, it thrives on-- freedom of enterprise and choice. Entrepreneurs and workers are free to further their own self-interest, subject to the rewards and penalties imposed by the market system itself. Of course, no economic system, including the market system, is flawless. In Chapter 4 we will explain several well-known shortcomings of the market system and examine the government policies that try to remedy them. The Demise of the Command Systems Our discussion of how a market system answers the five fundamental questions provides insights on why command systems of the Soviet Union, eastern Europe, and China (prior to its market reforms) failed. Those systems encountered two insurmountable problems. The Coordination Problem The first difficulty was the coordination problem. The central planners had to coordinate the millions of individual decisions by consumers, resource suppliers, and businesses. Consider the setting up of a factory to produce tractors. The central planners had to establish a realistic annual production target, for example, 1000 tractors. They then had to make available all the necessary inputs--labor, machinery, electric power, steel, tires, glass, paint, transportation--for the production and delivery of those 1000 tractors. Because the outputs of many industries serve as inputs to other industries, the failure of any single industry to achieve its output target caused a chain reaction of repercussions. For example, if iron mines, for want of machinery or labor or transportation, did not supply the steel industry with the required inputs of iron ore, the steel mills were unable to fulfill the input needs of the many industries that depended on steel. Those steel-using industries (such as tractor, automobile, and transportation) were unable to fulfill their planned production goals. Eventually the chain reaction spread to all firms that used steel as an input and from there to other input buyers or final consumers. The coordination problem became more difficult as the economies expanded. Products and production processes grew more sophisticated and the number of industries requiring planning increased. Planning techniques that worked for the simpler economy proved highly McConnell-Brue-Flynn: Microeconomics: Principles, Problems, and Policies, 18th Edition I. Introduction to Economics and the Economy 2. The Market System and the Circular Flow The McGraw-Hill Companies, 2009 CHAPTER 2 39 The Market System and the Circular Flow inadequate and inefficient for the larger economy. Bottlenecks and production stoppages became the norm, not the exception. In trying to cope, planners further suppressed product variety, focusing on one or two products in each product category. A lack of a reliable success indicator added to the coordination problem in the Soviet Union and China (prior to its market reforms). We have seen that market economies rely on profit as a success indicator. Profit depends on consumer demand, production efficiency, and product quality. In contrast, the major success indicator for the command economies usually was a quantitative production target that the central planners assigned. Production costs, product quality, and product mix were secondary considerations. Managers and workers often sacrificed product quality and variety because they were being awarded bonuses for meeting quantitative, not qualitative, targets. If meeting production goals meant sloppy assembly work and little product variety, so be it. It was difficult at best for planners to assign quantitative production targets without unintentionally producing distortions in output. If the plan specified a production target for producing nails in terms of weight (tons of nails), the enterprise made only large nails. But if it specified the target as a quantity (thousands of nails), the firm made all small nails, and lots of them! That is precisely what happened in the centrally planned economies. CONSIDER THIS . . . The Two Koreas North Korea is one of the few command economies still standing. After the Second World War, the Korean penisula was divided into North Korea and South Korea. North Korea, under the influence of the Soviet Union, established a command economy that emphasized government ownsership and central government planning. South Korea, protected by the United States, established a market economy based upon private ownership and the profit motive. Today, the differences in the economic outcomes of the two systems are striking: North Korea GDP GDP per capita Exports Imports Agriculture as % of GDP $40 billion* $1,800* $1.3 billion $2.7 billion 30 percent South Korea $1.2 trillion* $24,500* $326 billion $309.3 billion 3 percent *Based on purchasing power equivalencies to the U.S. dollar. Source: CIA World Fact Book, 2008, www.cia.gov. The Incentive Problem The command economies also faced an incentive problem. Central planners determined the output mix. When they misjudged how many automobiles, shoes, shirts, and chickens were wanted at the government-determined prices, persistent shortages and surpluses of those products arose. But as long as the managers who oversaw the production of those goods were rewarded for meeting their assigned production goals, they had no incentive to adjust production in response to the shortages and surpluses. And there were no fluctuations in prices and profitability to signal that more or less of certain products was desired. Thus, many products were unavailable or in short supply, while other products were overproduced and sat for months or years in warehouses. The command systems of the Soviet Union and China before its market reforms also lacked entrepreneurship. Central planning did not trigger the profit motive, nor did it reward innovation and enterprise. The route for getting ahead was through participation in the political hierarchy of the Communist Party. Moving up the hierarchy meant better housing, better access to health care, and the right to shop in special stores. Meeting production targets and maneuvering through the minefields of party politics were measures of success in "business." But a definition of business success based solely on political savvy was not conducive to technological advance, which is often disruptive to existing products, production methods, and organizational structures. The Circular Flow Model The dynamic market economy creates continuous, repetitive flows of goods and services, resources, and money. The circular flow diagram, shown in Figure 2.2 (Key Graph), illustrates those ORIGIN OF THE IDEA flows.

In the resource market, households sell resources and businesses buy them. Households (that is, people) own all economic resources either directly as workers or entrepreneurs or indirectly through their ownership of busi40 ness corporations. They sell their resources to businesses, which buy them because they are necessary for producing goods and services. The funds that businesses pay for resources are costs to businesses but are flows of wage, rent, interest, and profit income to the households. Productive resources therefore flow from households to businesses, and money flows from businesses to households.

The Market System and the Circular Flow The McGraw-Hill Companies, 2009 LAST Word Economist Donald Boudreaux Marvels at the Way the Market System Systematically and Purposefully Arranges the World's Tens of Billions of Individual Resources. In The Future and Its Enemies, Virginia Postrel notes the astonishing fact that if you thoroughly shuffle an ordinary deck of 52 playing cards, chances are practically 100 percent that the resulting arrangement of cards has never before existed. Never. Every time you shuffle a deck, you produce an arrangement of cards that exists for the first time in history. The arithmetic works out that way. For a very small number of items, the number of possible arrangements is small. Three items, for example, can be arranged only six different ways. But the number of possible arrangements grows very large very quickly. The number of different ways to arrange five items is 120 . . . for ten items it's 3,628,800 . . . for fifteen items it's 1,307,674,368,000. The number of different ways to arrange 52 items is 8.066 1067. This is a big number. No human can comprehend its enormousness. By way of comparison, the number of possible ways to arrange a mere 20 items is 2,432,902,008,176,640,000--a number larger than the total number of seconds that have elapsed since the beginning of time ten billion years ago--and this number is Lilliputian compared to 8.066 1067. What's the significance of these facts about numbers? Consider the number of different resources available in the world-- my labor, your labor, your land, oil, tungsten, cedar, coffee beans, chickens, rivers, the Empire State Building, [Microsoft] Windows, the wharves at Houston, the classrooms at Oxford, the airport at Miami, and on and on and on. No one can possibly count all of the different productive resources available for our use. But we can be sure that this number is at least in the tens of billions. Shuffling the Deck When you reflect on how incomprehensibly large is the number of ways to arrange a deck containing a mere 52 cards, the mind boggles at the number of different ways to arrange all the world's resources. If our world were random--if resources combined together haphazardly, as if a giant took them all into his hands and tossed them down like so many [cards]--it's a virtual certainty that the resulting combination of resources would be useless. Unless this chance arrangement were quickly rearranged according to some productive logic, nothing worthwhile would be produced. We would all starve to death. Because only a tiny fraction of possible arrangements serves human ends, any arrangement will be useless if it is chosen randomly or with inadequate knowledge of how each and every resource might be productively combined with each other. And yet, we witness all around us an arrangement of resources that's productive and serves human goals. Today's arrangement of resources might not be perfect, but it is vastly superior to most of the trillions upon trillions of other possible arrangements. How have we managed to get one of the minuscule number of arrangements that works? The answer is private property--a social institution that encourages mutual accommodation. Private property eliminates the possibility that resource arrangements will be random, for each resource owner chooses a course of action only if it promises rewards to the owner that exceed the rewards promised by all other available courses. [The result] is a breathtakingly complex and productive arrangement of countless resources. This arrangement emerged over time (and is still emerging) as the result of billions upon billions of individual, daily, small decisions made by people seeking to better employ their resources and labor in ways that other people find helpful.

The Market System and the Circular Flow The McGraw-Hill Companies, 2009 42 PART ONE Introduction to Economics and the Economy Product Market Next consider the lower part of the diagram, which represents the product market: the place where goods and services produced by businesses are bought and sold. In the product market, businesses combine resources to produce and sell goods and services. Households use the (limited) income they have received from the sale of resources to buy goods and services. The monetary flow of consumer spending on goods and services yields sales revenues for businesses. Businesses compare those revenues to their costs in determining profitability and whether or not a particular good or service should continue to be produced. The circular flow model depicts a complex, interrelated web of decision making and economic activity involving businesses and households. For the economy, it is the circle of life. Businesses and households are both buyers and sellers. Businesses buy resources and sell products. Households buy products and sell resources. As shown in Figure 2.2, there is a counterclockwise real flow of economic resources and finished goods and services and a clockwise money flow of income and consumption expenditures. Summary 1. The market system and the command system are the two broad types of economic systems used to address the economizing problem. In the market system (or capitalism), private individuals own most resources, and markets coordinate most economic activity. In the command system (or socialism or communism), government owns most resources and central planners coordinate most economic activity. 2. The market system is characterized by the private ownership of resources, including capital, and the freedom of individuals to engage in economic activities of their choice to advance their material well-being. Self-interest is the driving force of such an economy and competition functions as a regulatory or control mechanism. 3. In the market system, markets, prices, and profits organize and make effective the many millions of individual economic decisions that occur daily. 4. Specialization, use of advanced technology, and the extensive use of capital goods are common features of market systems. Functioning as a medium of exchange, money eliminates the problems of bartering and permits easy trade and greater specialization, both domestically and internationally. 5. Every economy faces five fundamental questions: (a) What goods and services will be produced? (b) How will the goods and services be produced? (c) Who will get the goods and services? (d) How will the system accommodate change? (e) How will the system promote progress? 6. The market system produces products whose production and sale yield total revenue sufficient to cover total cost. It does not produce products for which total revenue continuously falls short of total cost. Competition forces firms to use the lowest-cost production techniques. 7. Economic profit (total revenue minus total cost) indicates that an industry is prosperous and promotes its expansion. Losses signify that an industry is not prosperous and hasten its contraction. 8. Consumer sovereignty means that both businesses and resource suppliers are subject to the wants of consumers. Through their dollar votes, consumers decide on the composition of output. 9. The prices that a household receives for the resources it supplies to the economy determine that household's income. This income determines the household's claim on the economy's output. Those who have income to spend get the products produced in the market system. 10. By communicating changes in consumer tastes to entrepreneurs and resource suppliers, the market system prompts appropriate adjustments in the allocation of the economy's resources. The market system also encourages technological advance and capital accumulation, both of which raise a nation's standard of living. 11. Competition, the primary mechanism of control in the market economy, promotes a unity of self-interest and social interests. As directed by an invisible hand, competition harnesses the self-interest motives of businesses and resource supplier to further the social interest. 12. The command systems of the Soviet Union and prereform China met their demise because of coordination difficulties under central planning and the lack of a profit incentive. The coordination problem resulted in bottlenecks, inefficiencies, and a focus on a limited number of products. The incentive problem discouraged product improvement, new product development, and entrepreneurship. 13. The circular flow model illustrates the flows of resources and products from households to businesses and from businesses to households, along with the corresponding monetary flows. Businesses are on the buying side of the resource market and the selling side of the product market. Households are on the selling side of the resource market and the buying side of the product market. McConnell-Brue-Flynn: Microeconomics: Principles, Problems, and Policies, 18th Edition I.

Competition is the disciplinarian of the market economy. 7. In the 1990s thousands of "dot-com" companies emerged with great fanfare to take advantage of the Internet and new information technologies. A few, like Yahoo, eBay, and Amazon, have generally thrived and prospered, but many others struggled and eventually failed. Explain these varied outcomes in terms of how the market system answers the question "What goods and services will be produced?" LO3 8. KEY QUESTION With current technology, suppose a firm is producing 400 loaves of banana bread daily. Also assume that the least-cost combination of resources in producing those loaves is 5 units of labor, 7 units of land, 2 units of capital, and 1 unit of entrepreneurial ability, selling at prices of $40, $60, $60, and $20, respectively. If the firm can sell these 400 loaves at $2 per unit, will it continue to produce banana bread? If this firm's situation is typical for the other makers of banana bread, will resources flow to or away from this bakery good? LO3 9. KEY QUESTION Assume that a business firm finds that its profit is greatest when it produces $40 worth of product A. Suppose also that each of the three techniques shown in the table below will produce the desired output: LO3 a. With the resource prices shown, which technique will the firm choose? Why? Will production using that technique entail profit or loss? What will be the amount of that profit or loss? Will the industry expand or contract? When will that expansion or contraction end? b. Assume now that a new technique, technique 4, is developed. It combines 2 units of labor, 2 of land, 6 of capital, and 3 of entrepreneurial ability. In view of the resource prices in the table, will the firm adopt the new technique? Explain your Register to View AnswerSuppose that an increase in the labor supply causes the price of labor to fall to $1.50 per unit, all other resource prices remaining unchanged. Which technique will the producer now choose? Explain. d. "The market system causes the economy to conserve most in the use of resources that are particularly scarce in supply. Resources that are scarcest relative to the demand for them have the highest prices. As a result, producers use these resources as sparingly as is possible." Evaluate this statement.

DIAMONDS--INTERESTED IN BUYING ONE? Go to the Internet auction site eBay at www.ebay.com and select the category Jewelry and Watches, followed by Loose Diamonds and Gemstones, and then Diamonds, Natural. How many natural diamonds are for sale at the moment? Note the wide array of sizes and prices of the diamonds. In what sense is there competition among the sellers in this market? How does that competition influence prices? In what sense is there competition among buyers? How does that competition influence prices? 2. BARTER AND THE IRS Bartering occurs when goods or services are exchanged without the exchange of money. For some, barter's popularity is that it enables them to avoid paying taxes to the government. How might such avoidance occur? Does the Internal Revenue Service (IRS), www.irs.ustreas.gov treat barter as taxable or nontaxable income? (Type "bartering income" in the site's search tool.) How is the value of a barter transaction determined? What are some IRS barter examples? What does the IRS require of the members of so-called barter exchanges?
