In microeconomic theory, productive efficiency (or production efficiency) is a situation in which the economy or an economic system (e.g., bank, hospital, industry, country) operating within the constraints of current industrial technology cannot increase production of one good without sacrificing production of another good. [1]
The concept of minimum efficient scale is useful in determining the likely market structure of a market. For instance, if the minimum efficient scale is small relative to the overall size of the market (demand for the good), there will be a large number of firms.
In the short-run, perfectly competitive markets are not necessarily productively efficient, as output will not always occur where marginal cost is equal to average cost (MC = AC). However, in the long-run, productive efficiency occurs as new firms enter the industry. Competition reduces price and cost to the minimum of the long run average costs.
When drawing diagrams for businesses, allocative efficiency is satisfied if output is produced at the point where marginal cost is equal to average revenue. This is the case for the long-run equilibrium of perfect competition. Productive efficiency occurs when units of goods are being supplied at the lowest possible average total cost.
The structure of a well-functioning market is defined by the theory of perfect competition. Well-functioning markets of the real world are never perfect, but basic structural characteristics can be approximated for real world markets, for example: Many small buyers and sellers; Buyers and sellers have equal access to information; Products are ...
However, if the market does not expand at the same rate as production increases, overproduction crises can occur. According to Marx the capitalist system is therefore characterized by two tendencies, connected to economies of scale: towards a growing concentration and towards economic crises due to overproduction.
Competition energizes firms to seek productive efficiency gains and produce at lowest unit costs or risk losing sales to more efficient rivals. With market forms other than perfect competition, such as monopoly, productive inefficiency can persist, because the lack of competition makes it possible to use inefficient production techniques and ...
Productivity is the efficiency of production of goods or services expressed by some measure. Measurements of productivity are often expressed as a ratio of an aggregate output to a single input or an aggregate input used in a production process, i.e. output per unit of input, typically over a specific period of time.
