PERFECT COMPETITION, LONG-RUN PRODUCTION ANALYSIS: In the long run, a perfectly competitive firm adjusts plant size, or the quantity of capital, to maximize long-run profit. In addition, the entry and exit of firms into and out of a perfectly competitive market guarantees that each perfectly competitive firm earns nothing more or less than a normal profit. As a perfectly competitive industry reacts to changes in demand, it traces out positive, negative, or horizontal long-run supply curve due to increasing, decreasing, or constant cost.

MARGINAL COST AND MARGINAL PRODUCT: Because variable cost is largely associated with the cost of employing a variable input in the short run, it's possible to identify a connection between the marginal cost curve and the marginal product curve. In particular, the quantity of output in which marginal cost is at a minimum, is the same quantity of output produced by the variable input when the marginal product of the variable input is at a maximum. In addition, over the range of production in which the variable input experiences increasing marginal returns and marginal product increases, the marginal cost curve declines. And over the range of production in which the variable input experiences decreasing marginal returns brought on by the law of diminishing marginal returns and marginal product increases, the marginal cost curve is rising.

MARGINAL PHYSICAL PRODUCT The change in the quantity of total physical product resulting from a unit change in a variable input, keeping all other inputs unchanged. Marginal physical product, usually abbreviated MPP, is found by dividing the change in total physical product by the change in the variable input. Marginal physical product, which more often goes by the name marginal product (MP), is one of two measures derived from total physical product. The other is average physical product.
