辛亥革命时期 1882年上海电气公司开业后,随着1890年八国 联军的入侵,上海、汉口、天津、广州、北京,以 及东北等租界相继开办了一些以解决照明为主的公 用电业。同年华裔商人成立广州电灯公司,开始了 民族资本创办电力的历史。1904年比利时商人与北 洋军阀在天津签约成立了电车电灯公司,并于1906 年开始了中国交流电的历史。到1911年,全国发电 装机容量才有27万KW,有电的地方仅是上海、广 州、北京、香港、等中心城市和租界内,中国电力 工业处于刚刚起步的幼芽状态

Then =1-91=1(3+:2)(3+2n 可=-1-3)=1(4-+2)(1-2+a With 1 0 O: Thus, in equilibrium, we must have ai=.2. In fact, the two firms must sit in the middle By Proposition 2.1, Pi=p?=c Discussion

Problem set 1 Micro Theory S. Wang Question1.1. Show that“f(X)=f(x),Vx∈R,A>1” implies“f(A)= Af(x),Vx∈R,A>0.” estion 1.2. Use a Lagrange function to solve c(w1, w2, y) for the following problem

Problem set 3 Micro Susen Wang Try to do most problems in MWG(1995), Chapters 7-9 Question 3.1.(Mixed-Strategy Nash Equilibrium). A principal hires an agent to perform some service at a price(which is supposed to equal the cost of the service The principal and the agent have initial

then there exists AE R\ such that (Kuhn-Tucker condition) G(s') =0 and 1. Lagrange Method for Constrained Optimization FOC: D.L(,\)=0. The following classical theorem is from Takayama(1993, p.114). Theorem A-4 (Sufficieney). Let f and, i= ,..m, be quasi-concave, where Theorem A-1. (Lagrange). For f: and G\\, consider the following G=(.8 ) Let r' satisfy the Kuhn-Tucker condition and the FOC for (A.2). Then, x' problem is a global maximum point if max f() (1)Df(x') =0, and f is locally twice continuously differentiable,or

Thus, to find Nash equilibria in IN=N, A(Si)), uin, we use the conditions: for ach player i (1)he is indifferent among all strategies in St,and (2)any strategy in St is at least as good as any strategy in S Example 3.7.(Meeting in an Airport ). Mr Wang and Ms Yang are to meet in an irport. However, they do not know whether they are to meet at door a or door B. The payoffs are specified in the following
