问题: The expansion path for a constant returns to scale production function
(A) is a straight line through the origin with a slope greater than one
if w > v.
(B) is a straight line through the origin with a slope less than one
if w < v.
(C) is a striaght line through the origin though its slope cannot be
determined by w and v alone.
(D) has a postive slope but is not necessarily a straight line.
答案: (C)
我的想法: 我不知道要怎麽在满足固定规模报酬的生产函数下, 确定扩张线是通过原点
的直线. 我试着假设一个Cobb-Douglas生产函数满足一阶齐次, 确实是如此
请大家帮忙看一下, 谢谢!!
