2019年1月24日 · Marginal product of capital (MPK) is the incremental increase in total production that results from one unit increase in capital while keeping all other inputs constant. Identifying the marginal product of capital is important because firms take investment decisions by comparing their marginal product of capital with their cost of capital.

The marginal product of capital (MPK) is the amount of extra output the firm gets from an extra unit of capital, holding the amount of labor constant: M P K = F ( K + 1 , L ) − F ( K , L ) {\displaystyle {\mathit {MP}}_{K}=F(K+1,L)-F(K,L)}

The formula for the calculation of the marginal product of capital is as follows: Marginal Product of Capital (MPK) = Change in Total Output / Change in Capital. Where, Change in Total Output = Change in the units produced by the company which is calculated by subtracting the level of old production from the level of the new production units.

2013年1月9日 · 资本的边际产量(marginal product of capital; MPK)资本的边际产量是指多投入一个单位的资本（假定其它的投入因素恒定）所得到的产量的增量。 数学上的含义是对产量函数Production Function中的资本变量的一阶偏微分。

2020年1月15日 · MPK = Change in Total Product Output / Change in Capital. or. MPK = Δ P / Δ K. For example, suppose you own a small manufacturing plant that produces 20,000 units every month. You can lease additional equipment for $5,000 each month, resulting in an increased production of 30,000 units.

R是单位capital的return，P是外生的产品价格，MPK是marginal productivity of capital，也就是production function对capital做一阶偏导，是capital K和labor L的函数。 这里的production function的单位是产品数量。

2024年3月22日 · The Marginal Product of Capital (MPK) is a concept in economics that refers to the additional output or production yield resulting from a one-unit increase in the capital input, holding all other inputs constant. This capital input could be in the form of machinery, equipment, or technology used in the production process.

2024年9月10日 · The marginal product of capital (MPK) is the additional output produced by one more unit of capital, while holding all other inputs constant. How is the marginal product of capital calculated? The marginal product of capital is calculated by taking the change in total output and dividing it by the change in capital input.

2018年11月25日 · Cobb Douglas function 中，资本收入αY 为什么＝MPK *K ？ 这个函数的提出是道格拉斯询问柯布是否存在这样的一个生产函数，使得它能产生不变的严肃份额。 但资本收入αY 为什么＝MPK *K 呢？

2019年3月14日 · Formula. The mathematical equation for Cobb-Douglas function is as follows: $$ \text{Q}=\text{A}\times \text{K}^\alpha\times \text{L}^\beta $$ Where Q is the total product, K represents the units of capital, L stands for units of labor, A is the total factor productivity, and α and β are the output elasticities of capital and labor respectively.
