Culture means an entire way of life of a society, or of a people. Different cultures have their own patterns of life. It's rather than instinctive behavior. The diversity of culture shows different attitude to ideas of what is beautiful and ways to treat dead bod ies. But it has nothing to do with right or wrong, for it is simply that different people do the some things in different ways

Primary Readings: DL-Chapter 4; JR-Chapter 3; Varian-Chapter 7 In most economic models, we start with an agent's utility function. The utility function basically maps from bundles that the agent might choose, to the real line. The utility function is quite convenient: it can be maximized and manipulated using mathematical tools. But the question is are we imposing some hidden or desirable assumptions when we take this approach ?prefeent's

Chapter 6 presents the supply side of the market using an approach parallel to that of the demand side of the market in Chapter 5. The chapter presents the material in a way that illustrates the second core principle of the textbook, that marginal benefits should equal marginal costs Chapter 5 presents the demand curve as derived from marginal benefit and Chapter 6 presents the supply curve as derived from marginal costs

1.设A是n阶矩阵,且经过 Gauss消去法一步消去后变为an (0A2 证明: (1)如果A是实对称矩阵,那么A2也是对称的; (2)如果ala(i=1,2,L,n),称A为(按行)严格对角占优矩阵,那么A2也是严格对角 占优

This chapter introduces comparative advantage and shows that having people specialize in the production in which they are relatively more efficient allows the production of more of everything. It introduces the production possibilities curve and develops the production possibilities model to show precisely how specialization enhances the productive capacity of an economy
