The second proposition in the table concerns tariffs and import quotas, two policies that restrict trade among nations. For reasons we discuss more fully later in this text, almost all economists oppose such barriers to free trade. Nonetheless, over the years, presidents and Congress have chosen to restrict the import of certain goods. Why do policies such as rent control and trade barriers persist if the experts are united in their opposition? It may be that the realities of the political process stand as immovable obstacles. But it also may be that economists have not yet convinced enough of the public that these policies are undesirable. One purpose of this book is to help you understand the economist's view of these and other subjects and, perhaps, to persuade you that it is the right one. QUICK QUIZ: Why might economic advisers to the president disagree about a question of policy? 2-4 Let's Get Going
The first two chapters of this book have introduced you to the ideas and methods of economics. We are now ready to get to work. In the next chapter, we start learning in more detail the principles of economic behavior and economic policy. As you proceed through this book, you will be asked to draw on many of your intellectual skills. You might find it helpful to keep in mind some advice from the great economist John Maynard Keynes: The study of economics does not seem to require any specialized gifts of an unusually high order. Is it not . . . a very easy subject compared with the higher branches of philosophy or pure science? An easy subject, at which very few excel! The paradox finds its explanation, perhaps, in that the master-economist must possess a rare combination of gifts. He must be mathematician, historian, statesman, philosopher–in some degree. He must understand symbols and speak in words. He must contemplate the particular in terms of the general, and touch abstract and concrete in the same flight of thought. He must study the present in the light of the past for the purposes of the future. No part of man's nature or his institutions must lie entirely outside his regard. He must be purposeful and disinterested in a simultaneous mood; as aloof and incorruptible as an artist, yet sometimes as near the earth as a politician. It is a tall order. But with practice, you will become more and more accustomed to thinking like an economist. h In the News: Environmental Economics Some economists are helping to save the planet. Green Groups See Potent Tool in Economics By Jessica E. Vascellaro Many economists dream of getting high-paying jobs on Wall Street, at prestigious think tanks and universities or at powerful government agencies like the Federal Reserve. But a growing number are choosing to use their skills not to track inflation or interest rates but to rescue rivers and trees. These are the "green economists," more formally known as environmental economists, who use economic arguments and systems to persuade companies to clean up pollution and to help conserve natural areas.
