标题[请益] 国际贸易(比较利益)
时间Thu May 2 09:38:34 2013
a country(Home)is populated with workers who produce either food(F)
or clothing(C). There are 200 workers producing food and 100 producing
clothing—these numbers are fixed in the short run. Each food worker
produces 6 units of food and each clothing worker produces 3 of clothing.
Workers own the output they produce and can trade with another. All
workers share the same prefereneces over food and clothing represented
by the utility function.
U(Dc,DF)=(Dc^1/3)(DF^2/3)
there also exists another country (Foreign) that looks surprising like the
Home country except that there are 600 food workers and 300 clothing workers
in this country. These workers have different(lower) productivity level: a
food worker can produce only 1 unit of food while a clothing worker can
only produce 2 units of clothing. The workers in Foreign share the same
preferences as those in Home.
now assume that all workers belong to represented"familites"each containing
2 food workers and 1 clothing workers.
Question:
1.describe how the consumption pattern(the number of units food and
and clothing consumed) of the "familites" change between autarky and the
trade equilibrium. Are the "familites" in both countries unambiguously
better-off?
我想请问,上面题目是指,现在以"familites"为一个单位吗,而这一个单位,可以
生产 2 food and 1 clothing吗?那这样的话。那对於Home的clothing的相对价格就为
6*2/3*1=4。这样想对吗??
