SHORT-RUN SUPPLY CURVE: For a perfectly competitive firm, the marginal cost curve that lies above the average variable cost curve. This segment of the marginal cost guides a perfectly competitive firm's profit maximizing production as it equates price to marginal cost. Because the marginal cost curve is positively sloped (due to the law of diminishing marginal returns), each firm's supply curve and the market supply curve are also positively sloped. The law of diminishing marginal returns thus provides an explanation for the law of supply. However, this only works for firms with NO market control. Monopoly, monopolistic competition, and oligopoly, with market control, do not achieve the same result.

INFORMATION The transfer of knowledge from one person to another. Information is a flow concept. It requires someone (or something) to do the sending and someone to do the receiving. Information is a valuable commodity that provides benefits, but also incurs an opportunity cost to produce, meaning information is never perfect or complete. The existence of asymmetric information (some have more information than others) gives rise to the problems of adverse selection, moral hazard, and the principal-agent problem.

The Sick State Of HEALTH CAREOur pedestrian's guide to the economy would be remiss if we failed to stroll past the Shady Valley Memorial Hospital and my very own physician's place of business, the Dr. Dowrimple T. Bedside Family Clinic, to examine the considerable controversy over health care.
