<P>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 &frac34;. </P>
<P>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<FONT size=4>短期和长期</FONT>来讨论: </P>


<P>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<BR>capital of a country, without affecting the labour force. Suppose the economy was at<BR>its steady-state equilibrium before the event. Describe and illustrate graphically how<BR>the economy will adjust to the fall in capital, assuming that the saving rate is equal to<BR>20%, the depreciation rate is equal to 10% and the population growth rate is equal to<BR>5%. The production function is given by Y = K1/4 L &frac34;. Suppose the size of the<BR>population (labour force) is equal to 2.<BR>Describe and explain how the following variables will evolve: Output, output per<BR>worker, capital and capital per worker. Make sure you describe both the short-run and<BR>long-run effects of the catastrophe.</P>

<P>大家想到什么说什么吧,不是非要完美的答案的</P>[em04][em04][em04][em04]
