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.

This translates into a positively-sloped supply curve for profit-maximizing competitive firms.
