PERFECT COMPETITION AND SHORT-RUN SUPPLY CURVE: A perfectly competitive firm's supply curve is that portion of its' marginal cost curve that lies above the minimum of the average variable cost curve. A perfectly competitive firm maximizes profit by producing the quantity of output that equates price and marginal cost. As such, the firm moves along it's marginal cost curve in response to alternative prices. Because the marginal cost curve is positively sloped due to the law of diminishing marginal returns, the firm's supply curve is also positively sloped.

REAL-BALANCE EFFECT A change in aggregate expenditures on real production made by the household, business, government, and foreign sectors that results because a change in the price level alters the purchasing power of money. This is one of three effects underlying the negative slope of the aggregate demand curve associated with a movement along the aggregate demand curve and a change in aggregate expenditures. The other two are interest-rate effect and net-export effect. The real-balance effect is somewhat analogous to the income effect underlying the negative slope of the market demand curve.
