Ronald William Shephard (November 22, 1912 – July 22, 1982) was professor of engineering science at the University of California, Berkeley. [1]He is best known for two results in economics, now known as Shephard's lemma and the Shephard duality theorem.
The difference in the value of the production values (the output value) and costs (associated with the factors of production) is the calculated profit. Efficiency, technological, pricing, behavioural, consumption and productivity changes are a few of the critical elements that significantly influence production economically.
The total cost curve, if non-linear, can represent increasing and diminishing marginal returns.. The short-run total cost (SRTC) and long-run total cost (LRTC) curves are increasing in the quantity of output produced because producing more output requires more labor usage in both the short and long runs, and because in the long run producing more output involves using more of the physical ...
For example, the manufacturing cost of a car (i.e., the costs of buying inputs, land tax rates for the car plant, overhead costs of running the plant and labor costs) reflects the private cost for the manufacturer (in some ways, normal profit can also be seen as a cost of production; see, e.g., Ison and Wall, 2007, p. 181).
Shephard's lemma is a major result in microeconomics having applications in the theory of the firm and in consumer choice. [1] The lemma states that if indifference curves of the expenditure or cost function are convex, then the cost minimizing point of a given good with price is unique.
The cost can comprise any of the factors of production (including labor, capital, or land) and taxation. The theory makes the most sense under assumptions of constant returns to scale and the existence of just one non-produced factor of production. With these assumptions, minimal price theorem, a dual version of the so-called non-substitution ...
The cost-volume-profit analysis is the systematic examination of the relationship between selling prices, sales, production volumes, costs, expenses and profits. This analysis provides very useful information for decision-making in the management of a company.
The marginal cost can also be calculated by finding the derivative of total cost or variable cost. Either of these derivatives work because the total cost includes variable cost and fixed cost, but fixed cost is a constant with a derivative of 0. The total cost of producing a specific level of output is the cost of all the factors of production.
