一场自然灾难毁坏了一个国家一半的资本(capital),劳动力(labor force)没有损失.在这场灾难前,经济处于稳定状态(steady-state).运用图来解释经济会因此发生怎样的变化.假设S=20%, 折旧率= 10% 人口增长率=5%. 生产函数是 Y = K1/4 L ¾.

假设人口大小为2( the size of the population (labour force) is equal to 2).解释 产出,每个工人的产出,资本,每个工人的资本是如何变化.请分短期和长期来讨论:

这是自己翻译的,翻得比较生硬,以下是原题--Suppose that a natural catastrophe destroys half of the
capital of a country, without affecting the labour force. Suppose the economy was at
its steady-state equilibrium before the event. Describe and illustrate graphically how
the economy will adjust to the fall in capital, assuming that the saving rate is equal to
20%, the depreciation rate is equal to 10% and the population growth rate is equal to
5%. The production function is given by Y = K1/4 L ¾. Suppose the size of the
population (labour force) is equal to 2.
Describe and explain how the following variables will evolve: Output, output per
worker, capital and capital per worker. Make sure you describe both the short-run and
long-run effects of the catastrophe.

大家想到什么说什么吧,不是非要完美的答案的
