||Economics studies how we use our scarce resources to specize in production and to exchange and consume goods and services. Economics is usually divided into microeconomics and macroeconomics. The former studies the economic decision making of the individual participants in the economy. The latter studies total output, total employment and unemployment, and the general movement in prices. Because of time limited, the subject of this course will only introduce general conception of microeconomics and its analytic methods, such as supply-demand law, theories of consummer and producer behavior, type of markets... and so on. It is expected that the students can have a general idea through examples and exercises, and they can do further reseaches after studying these course. We hope that will them to understand the economic reports in newspapers, magazines and economic policies of government.
