4 贸易对两国经济的影响
4.1 相对价格和贸易模式
另外， 值得注意的是， 7/6 这个价格的确低于我们最开始任意假定的世界价格 1.5 （非均衡价格） 。
说明： 在这个例子中， 自己自足时， 中国的衣服价格为 3/4， 美国的衣服价格为 2。 自由贸易时， 衣服和粮食的市场是统一的， 衣服的世界价格为 7/6 （均衡价格） ， 这个价格介于 3/4 和 2 之间。
表格 2：中国和美国的资源禀赋
劳动 资本
要素密集度：某种产品的生产对不同要素的需要程度。 充裕要素：一国（相对于外国）供给相对较多的要素。比如表格 2 中，中国的充裕要素是劳 动。 稀缺要素：一国（相对于外国）供给相对较少的要素。
几个问题： 问题 1：在上面的要素资源和技术下，中国的生产可能性曲线是什么样子的？中国将选择生 产可能性曲线上的哪一点？这个选择依赖于衣服的相对价格么？美国呢？ 问题 2：封闭经济下，中国的消费点在哪里，产品的相对价格是多少？美国呢？ 问题 3：封闭经济下，中国的工资和租金率为多少？美国呢？哪个国家的工资（相对）高？ 问题 4：开放经济下，若衣服价格为 1.5，中国出口什么，进口什么？美国呢？国际贸易平 衡吗？衣服价格会怎样变动？ 问题 5：开放经济下，均衡的衣服价格是多少？中国均衡的工资和利率各是多少？美国呢？ 中国和美国的工资差异消除了么？
1 模型描述
1.1 模型假定
(1). 两个国家（中国和美国） ，都用两种要素（资本和劳动）生产两种产品（衣服和粮食） 。 (2). 两国代表消费者的偏好相同。 (3). 两国的生产技术相同， 技术具有规模报酬不变和边际产出递减的特征， 无要素密集度逆 转。 (4). 要素不能在国家之间流动，但可以在一国内的不同部门自由流动；产品可以自由贸易。 (5). 所有市场都是完全竞争的。 (6). 相对要素禀赋差异很小。

HORIZONTAL SUMMATION
Consumer Surplus
• Consumers buy goods because it makes them better off
MARKET DEMAND
WITH NETWORK EFFECTS
Demand dependence: • The utility of a good derived by a consumer depends on how many other
consumers buy/use the good • Consequently individual and market demand depends on aggregate number
market demand. • Key role of expectations: expected popularity of a “network good” critical in
ensuring its popularity. • “Chicken and egg” problem: how to sell the first unit when it has little/no

There is no "Law of Supply"
market supply curve may be upward sloping, vertical, horizontal, or downward sloping
Supply effects of other variables
shift in a variable other than price of pork causes the entire supply curve to shift
curves: Q1 = D1(P) Q2 = D2(P) • total quantity demanded = horizontal sum of quantity each consumer demands at each given price: Q = Q1 + Q2 = D1(P) + D2(P)
General supply function
Summing supply curves
total supply curve • horizontal summation of individual supply

Ch09 Perfect Competition and Pure Monopoly(经济学,英文版-复旦,周翼)


Perfect competition
Characteristics of a perfectly competition market

many buyers and sellers
–
so no individual believes that their own action can affect market price so face a horizontal demand curve

firms take price as given
–
the product is homogeneous perfect customer information free entry and exit of firms
9.1
The supply curve under perfect competition (1)
If the expansion of the industry pushes up input prices (e.g. wages) then the long-run supply curve will not be horizontal, but upward-sloping.
9.8
q*
Adjustment to an increase in market demand: the short run Suppose a perfectly competitive market starts in equilibrium at P0Q0.
9.11
Profit maximization by a monopolist
Profits are maximized where MC = MR at Q1P1. In this position, AR is greater than AC AC so the firm makes profits above the opportunity cost of capital

1.2 Axioms on preferences over gambles
1. Completeness. 2. Transitivity. 3. Given Axioms 1 and 2, we can rank all outcomes in A. (ai can be viewed as a degenerate gamble that yields outcome 1 with probability one.) Without loss of generality, we assume a1 a2... an.
jectively defined. 3. A compound gamble is a gamble whose prizes are gambles (simple or compound). For any compound gambles, we can calculate the probability of each outcome. (I use the term “prize” to refer to what one may receive from a gamble. A prize may be another gamble or an outcome in A.) 4. Example: suppose A = {+1, −1}. g1 = (p1 ◦ 1, (1 − p1) ◦ −1) g2 = (p2 ◦ 1, (1 − p2) ◦ −1) g3 = (q ◦ g1, (1 − q ) ◦ g2)

• how should that firm change its output level to maximize its profit
• how does its maximum profit change?

Interpreting output rules
Calculus
Shut-down rules
• apply to all firms in SR and LR
year • your opportunity cost is $25,000, • so you have an economic loss of $5,000
Profit function
Two steps to maximizing profit
to maximize its profit, any firm (not just competitive firms) must answer two questions: • output decision: if the firm produces, what output level, q*, maximizes its profit or minimizes its loss? • shut-down decision: is it more profitable to produce q* or to shut down and produce no output?
【复旦大学本科讲义-平狄克微观经济学PPT】General Equilibrium-英文版

• through demand • through supply
• because output in one market is an input in another
Partial vs. General Equilibrium
• study equilibrium in several—but not all— markets simultaneously
• shock in one market has spillover effect in another market
• general-equilibrium analysis takes account of spillover, unlike partial-equilibrium analysis

General Equilibrium
• Magnitude of spillover effects • General vs. partial equilibrium models
