In economics, the marginal cost is the change in the total cost that arises when the quantity produced is increased, i.e. the cost of producing additional quantity. [1] In some contexts, it refers to an increment of one unit of output, and in others it refers to the rate of change of total cost as output is increased by an infinitesimal amount.
Likewise, the marginal product of capital refers to the additional production of output that results from using an additional unit of physical capital (machinery, etc.). If very small increments are being considered, so that calculus is used, then this ratio of incremental amounts is a derivative (for example, the marginal propensity to consume ...
Similarly, if the third kilogram of seeds yields only a quarter ton, then the marginal cost equals per quarter ton or per ton, and the average cost is per 7/4 tons, or /7 per ton of output. Thus, diminishing marginal returns imply increasing marginal costs and increasing average costs. Cost is measured in terms of opportunity cost. In this case ...
Marginal cost (MC) relates to the firm's technical cost structure within production, and indicates the rise in total cost that must occur for an additional unit to be supplied to the market by the firm. [1] The marginal cost is higher than the average cost because of diminishing marginal product in the short run. [1]
It compares a firm's price of output with its associated marginal cost where marginal cost pricing is the "socially optimal level" achieved in market with perfect competition. [41] Lerner (1934) believes that market power is the monopoly manufacturers' ability to raise prices above their marginal cost. [ 42 ]
The marginal cost curve is the marginal cost of an additional unit at each given quantity. The law of diminishing returns states the marginal cost of an additional unit of production for an organisation or business increases as the quantity produced increases. [8] Consequently, the marginal cost curve is an increasing function for large ...
Marginal revenue is a fundamental tool for economic decision making within a firm's setting, together with marginal cost to be considered. [9] In a perfectly competitive market, the incremental revenue generated by selling an additional unit of a good is equal to the price the firm is able to charge the buyer of the good.
At the highest level of generality, a marginal cost is a marginal opportunity cost. In most contexts, marginal cost refers to marginal pecuniary cost, that is to say marginal cost measured by forgone money. A thorough-going marginalism sees marginal cost as increasing under the law of diminishing marginal utility, because applying resources to ...
