NO.PZ2016010801000060 问题如下 Country X is a velopecountry anaims to realize a continuously economic growth in the long term. The least feasible wis to A.increase the labor supply B.increase the physiccapitof ealabor C.increase the proctivity per worker B is correct. The rate of increase in labor foranlabor proctivity will termine the sustainable economic growth. A velopecountry keeps the capitper worker a high level anis experiencing the minishing of marginproctivity. Therefore increase the physiccapitof ealabor is not a feasible methoto keep a continuous economic growth.考点Economic Growth anSustainability解析动力和劳动生产率的增长速度将决定经济的可持续增长。发达国家人均资本保持在较高水平，边际生产率递减效应明显。因此，增加每个劳动力的实物资本不是保持经济持续增长的可行方法。所以B入选。增加劳动力和劳动力的生产率将会有效提高一国经济经济增长，所以A,C不入选。 边际收益递减中是说TQ和L的关系吧，就是劳动力增加太多之后，MQ会开始减少，这跟B有什么关系呢
NO.PZ2016010801000060 对发达国家来说，增加劳动力难道不是收效甚微吗？麻烦老师下
NO.PZ2016010801000060 %lta(y)=%lta(A)+%lta(k)这个式子里没有labor，那是不是说明labor对于国家长期的g per capita增加没有影响呢？谢谢
答案解析 The rate of increase in labor foranlabor proctivity will termine the sustainable economic growth. A velopecountry keeps the capitper worker a high level anis experiencing the minishing of marginproctivity. Therefore increase the physiccapitof ealabor is a feasible methoto keep a continuous economic growth. 最后一句话是不是说反了啊
题目不是问最不可能的么？怎么答案最后一句又的是最可能？？？
