Economic law stating that if one input used in the manufacture of a product is increased while all other inputs remain fixed, a point will eventually be reached at which the input yields progressively smaller increases in output. For example, a farmer will find that a certain number of farm labourers will yield the maximum output per worker. If that number is exceeded, the output per worker will fall.

The principle that further inputs into a system produce ever lower increases in outputs. Any extra input will not produce an equal or worthwhile return. Thus, while early applications of fertilizer may increase yields, further applications will not see a corresponding rise in output, and even further applications may actually damage the crop, as excessive fertilizer can burn plant tissue.

diminishing returns, law of, in economics, law stating that if one factor of production is increased while the others remain constant, the overall returns will relatively decrease after a certain point. Thus, for example, if more and more laborers are added to harvest a wheat field, at some point each additional laborer will add relatively less output than his predecessor did, simply because he has less and less of the fixed amount of land to work with. The principle, first thought to apply only to agriculture, was later accepted as an economic law underlying all productive enterprise. The point at which the law begins to operate is difficult to ascertain, as it varies with improved production technique and other factors. Anticipated by Anne Robert Jacques Turgot and implied by Thomas Malthus in his Essay on the Principle of Population (1798), the law first came under examination during the discussions in England on free trade and the corn laws. It is also called the law of decreasing returns and the law of variable proportions.

An economic law propounded by David Ricardo, also called the law of diminishing marginal returns. It expresses a relationship between input and output, stating that adding units of any one input (labor, capital, etc.) to fixed amounts of the others will yield successively smaller increments of output.

  • In common usage, the “point of diminishing returns” is a supposed point at which additional effort or investment in a given endeavor will not yield correspondingly increasing results.
