1 The field of economics studies the basic problems that every economy must face: what goods will be produced and for whom they will be produced. The underlying assumptions of the field are that resources are scarce, or at least limited, and that not all human needs and desires can be met. How to allocate limited resources in the fairest and most efficient way is a principal concern of economists.
2 Two major branches of economics are macroeconomics and microeconomics. Macroeconomics is concerned with how a national or regional economy behaves as a whole. It analyzes aggregate data in such areas as the gross national product, general price levels, and total employment. Macroeconomists examine how national income, output, consumption, inflation, and investment influence each other, and try to determine why any imbalance among them occurs. They develop models to explain the interplay of forces and to make economic forecasts. Governments use macroeconomic models to guide the creation and evaluation of economic policy. Large corporations use macroeconomic models in developing their business strategy.
3 Microeconomics is mainly focused on economic activity in the individual case, whether it is a single firm, commodity, or group of consumers. It studies how individuals, households, and companies make decisions to allocate limited resources. It is especially interested in what determines the price levels of goods and services in specific markets. Moreover, it analyzes market failure by examining where and why markets fail to produce efficient results.

Response Time - 60 secondsListen to part of a conversation between two students.
W: How are you, Jim?
M: Busy with school, and looking for a part-time job. I’ve been offered two jobs, and the hard part is deciding which one to take.
W: Oh, really? What sort of jobs?
M: One is a dinner waiter in a restaurant. I’d have to work until late at night, but I’d make good money in tips. The other is a night clerk in the physics lab, here on campus. It doesn’t pay much, but it would be quiet, and I could study at the desk.
W: That’s a difficult choice. You have to decide what’s more important to you—money or time to study. You need to think about how the job would affect your studies. Didn’t you tell me that you were having trouble in some of your classes?
M: Yeah ... well, not really, but I should spend more time studying.
W: You need to think about how much stress the job would cause, I mean, how it might affect your health. Would you get enough sleep?
M: I don’t know.
W: Well, it’s a difficult choice. You have to decide what your priority is.
