Explain the importance of scarcity, choice, and opportunity cost, and they are illustrated by the production possibilities boundary. 3. Describe the circular flow of income and expenditure. 4. Explain that all economies are mixed economies, having elements of free markets, tradition, and government intervention. 1. Describe the market economy as a self-organizing entity in which order emerges from a large number of decentralized decisions.

Self-interest, not benevolence, is the foundation of economic order. Who or what provides the goods and services individuals desire? The Complexity of the Modern Economy

Adam Smith (1723-1790) In The Wealth of Nations, Smith was the first to develop this insight fully: “It is not from the benevolence of the butcher, the brewer, or the baker, that we expect our dinner, but from their regard to their own interest. We address ourselves, not to their humanity but to their self-love, and never talk to them of our own necessities but of their advantages.” Efficiency

Institutions, created by the state, protect private property and enforce contractual obligations. Prices and quantities are set in (relatively) free markets in which individuals trade voluntarily.

All rights reserved. 1-6 Scarcity, Choice, and Opportunity Cost Resources Economics is the study of the use of scarce resources to satisfy unlimited human wants. A society’s resources are divided into land, labor, and capital. Economists refer to resources as factors of production. Outputs are goods (tangibles) or services (intangibles).

7. Copyright © 2008 Pearson Addison-Wesley. All rights reserved. 1-7 Scarcity and Choice Resources can produce only a fraction of the goods and services desired by people. Scarcity implies the need for choice. Every choice has an associated cost -- opportunity cost.

11. Copyright © 2008 Pearson Addison-Wesley. All rights reserved. 1-11 Four Key Economic Problems Will the economy be inside the production possibilities boundary — inefficiently used resources? 1. What Is Produced and How? Resource allocation determines the quantities of various goods that are produced. In terms of our previous illustration, what combination of civilian and military goods will be chosen? Any economy must have some mechanism to deal with decisions about resource allocation.

12. Copyright © 2008 Pearson Addison-Wesley. All rights reserved. 1-12 Will the economy consume exactly what it produces? 2. What Is Consumed and By Whom? What determines how economies distribute total output? Why do some people get a lot while others get only a little? Microeconomics is the study of the allocation of resources as it is affected by the workings of the price system.

An economy is operating inside its production possibilities boundary if some resources are idle. Under what circumstances are workers seeking jobs unable to find them? Should governments worry about idle resources? Is there anything governments can do about them? Macroeconomics deals with questions relating to the idleness of resources and the growth of productivity.

16. Copyright © 2008 Pearson Addison-Wesley. All rights reserved. 1-16 Individuals own factors of production. They sell the services of these factors to producers in factor markets and receive payment in return. The payment becomes their (factor) incomes. Producers transform factor services into goods and services, which they then sell to individuals in goods markets, receiving payment in return. The payment becomes the incomes of producers. The Circular Flow

18. Copyright © 2008 Pearson Addison-Wesley. All rights reserved. 1-18 The Complexity of Production Production usually displays two characteristics noted long ago by Adam Smith: specialization and the division of labor. Specialization is the allocation of different jobs to different people. It is more efficient than self-sufficiency because: Individual abilities differ -- comparative advantage. Focusing on one activity leads to improvements -- learning by doing. Division of labor extends the idea of specialization for the production of a single good or service.

All rights reserved. 1-19 Globalization Underlying modern globalization is the rapid reduction of transportation and communication costs in the last half of the 20th century. Through globalization, national economies are ever more linked to the global economy. In this course we will discuss the extent to which the process of globalization changes markets and changes the way government policy can influence economic outcomes.

20. Copyright © 2008 Pearson Addison-Wesley. All rights reserved. 1-20 Markets and Money Specialization must be accompanied by trade. Money eliminates the cumbersome system of barter by separating the transactions involved in the exchange of products, thereby facilitating specialization and trade.

Types of Economic Systems There are three pure types of economic systems: Traditional Command Free-Market In practice, every economy is a mixed economy, in the sense some decisions are made by firms and households and some by the government.

All rights reserved. 1-22 The Great Debate A century after Adam Smith, Karl Marx (1818-1883) argued that free-market economies could not be relied upon to generate a “just” distribution of output. He argued for the benefits of a centrally planned economic system. Beginning with the Soviet Union in the 1920s, some countries (Eastern Europe and China) inspired by Marx adopted socialist/communist systems.

23. Copyright © 2008 Pearson Addison-Wesley. All rights reserved. 1-23 By the last few decades of the 20th century, most of these countries were unable to provide their citizens the rising living standards that existed in the more free-market economies. In the last two decades of the 20th century, those countries abandoned their central planning systems and began the transition back to market economies.

Governments also intervene to: correct market failures provide public goods offset the effects of externalities Markets often work well, but sometimes government policy can improve the outcome for society as a whole.
