TOBIN'S Q: A financial measure of a firm's returns, calculated by dividing the market value of the firm (that is, the market value of its outstanding stock and debt) by the replacement costs of the firm's assets. According to James Tobin of Yale University, Nobel Laureate in Economics in 1981, if this ratio is greater than 1 it means that the firm is earning a rate of return higher than that justified by the costs of its assets. That is, Tobin suggested that the ratio of the market value of a firm to the replacement costs of its assets should be close to 1.

MARGINAL COST AND LAW OF DIMINISHING MARGINAL RETURNS

Decreasing then increasing marginal cost, reflected by a U-shaped marginal cost curve, is the result of increasing then decreasing marginal returns. In particular the decreasing marginal returns is caused by the law of diminishing marginal returns. As such, the law of diminishing marginal returns affects not only the short-run production of a firm but also the cost of short-run production. This translates into a positively-sloped supply curve for profit-maximizing competitive firms.
