	【资料名称】rinciples of Economics, 6 edition     【资料描述】: 　　Economics is a study of mankind in the ordinary business of life.” So 　　wrote Alfred Marshall, the great 19th-century economist, in his textbook, 　　Principles of Economics. Although we have learned much about the economy 　　since Marshall’s time, this definition of economics is as true today as it 　　was in 1890, when the first edition of his text was published. 　　Why should you, as a student at the beginning of the 21st century, embark on 　　the study of economics? There are three reasons. 　　The first reason to study economics is that it will help you understand the 　　world in which you live. There are many questions about the economy that might 　　spark your curiosity. Why are apartments so hard to find in New York City? Why 　　do airlines charge less for a round-trip ticket if the traveler stays over a Saturday 　　night? Why is Johnny Depp paid so much to star in movies? Why are living standards 　　so meager in many African countries? Why do some countries have high 　　rates of inflation while others have stable prices? Why are jobs easy to find in 　　some years and hard to find in others? These are just a few of the questions that a 　　course in economics will help you answer. 　　The second reason to study economics is that it will make you a more astute 　　participant in the economy. As you go about your life, you make many economic 　　decisions. While you are a student, you decide how many years to stay in school. 　　Once you take a job, you decide how much of your income to spend, how much 　　to save, and how to invest your savings. Someday you may find yourself running 　　a small business or a large corporation, and you will decide what prices to charge 　　for your products. The insights developed in the coming chapters will give you 　　a new perspective on how best to make these decisions. Studying economics will 　　not by itself make you rich, but it will give you some tools that may help in that 　　endeavor. 　　The third reason to study economics is that it will give you a better understanding 　　of both the potential and the limits of economic policy. Economic questions 　　are always on the minds of policymakers in mayors’ offices, governors’ mansions, 　　and the White House. What are the burdens associated with alternative forms of 　　taxation? What are the effects of free trade with other countries? What is the best 　　way to protect the environment? How does a government budget deficit affect 　　the economy? As a voter, you help choose the policies that guide the allocation of 　　society’s resources. An understanding of economics will help you carry out that 　　responsibility. And who knows: Perhaps someday you will end up as one of those 　　policymakers yourself. 　　Thus, the principles of economics can be applied in many of life’s situations. 　　Whether the future finds you reading the newspaper, running a business, or sitting 　　in the Oval Office, you will be glad that you studied economics. 　　N.
