　　Economics is a way of understanding human behavior and of solving problems that characteristically involve scarcity. Economics is important because it provides a method to help make clear a wide range of problems affecting human welfare. It has traditionally been thought that economics is concerned with such broad topics as wealth and income; the production and distribution of goods; money and banking; the determination of prices; employment and unemployment; short-term changes in the level of business activity; and long-term changes in the level of business activity; and long term trends that make some nations rich and keep others poor. But economies has actually been concerned also with the welfare, working and living conditions, and freedom of the individual person. The nineteenth-century English economist Alfred Mar-shall sought to show the universal importance of economics when he said that it is a study of man in the ordinary business of life. He also noted that economics examines that part of individual social activity that is concerned with getting and using the materials necessary for health and happiness.

　　Economics is a study of wealth and an important part of the study of man. This is because man's character has been shaped by his daily work, and the material resources he gains from it. In general, then, economics is about individual and social behavior and values. You cannot understand much about your society without having some knowledge of economies.
