04.单选题 收藏 标记 纠错 To minimize total costs for a desired level of output, which of the following is the most efficient combination of labor and capital? A Equalize marginal product obtained per dollar spent on labor to the marginal product per dollar spent on capital. B Equalize average product of labor to the average product of capital. C Equalize marginal product per unit of labor to the marginal product per unit of capital. 查看解析 上一题 下一题 正确答案A 您的答案A本题平均正确率:55% Economies of scale and diseconomies of scale难度:一般 推荐: 答案解析 Costs are minimized when substitution of labor for capital (or the reverse) does not result in any cost savings, which is the case when the marginal product per dollar spent is equalized across inputs. 问:这道题 能不能讲解的再详尽一些?因为 基础课视频里这方面几乎没有涉及到?
查看试题 已回答Which of the following most accurately describes economies of scale? A Economies of scale increase at a decreasing rate. B Economies of scale occur when long-run unit costs fall as output increases. C Economies of scale are dependent on short-run average costs. 查看解析 上一题 下一题 正确答案B 您的答案B本题平均正确率:76% Economies of scale and diseconomies of scale难度:一般 推荐: 答案解析 Economies of scale occur when the percentage increase in output is greater than the percentage increase in the cost of all inputs. Economies of scale occur over the range where the long-run average cost curve slopes downward. 问:1.对应我画的图(左),看规模效应这一边 这条包络线的斜率的绝对值应该是越来越小,所以意味着 规模经济效应以一个降低的速率上升吧,不正是A形容的吗?2.我画的图(右),讲解里说 规模经济的另一种理解:Q增增 TC增,如果对应图的话 是不是我在图中用绿色线描出来的部分?

精品问答
- Q6,为啥要少抽失败的,少抽不就不能真实反应情况了吗?
- Q3:解析里面Team Purple’s conclusion (the externalities associated with human capital is the most important determinant in predicting the occurence of convergence) implies that the production function is a straight line, and is compatible with non-convergence.这段话中 externalities associated with human capital具体是什么?怎么得到the production function is a straight line这个结论呢?
- Risk Budget and risk parity 第二道思考题,里面的Variance是不是完全是个冗余信息,给来误导的呀?
- 为什么半年付息 算ytm是乘以2 而年化的麦考利久期是除以2
- Growth due to capital deepening 是αΔK/K还是ΔK/K
- 为什么TC 的切点对应是AVC的最低点?
- 老师,给最新的信息更高权重为什么不是availability bias呢?
- BG检验就是T检验吗?如果理解错误的话 T检验是什么?
