AS-AD MODEL: An economic model relating the price level and real production that is used to analyze business cycles, gross domestic product, unemployment, inflation, stabilization policies, and related macroeconomic phenomena. The AS-AD model, inspired by the standard market model, captures the interaction between aggregate demand (the buyers) and short-run and long-run aggregate supply (the sellers).

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.

A resource with an available quantity less than its desired use. Scarce, or economic, resources are also called factors of production and are generally classified as either labor, capital, land, or entrepreneurship. Scarce resources are the workers, equipment, raw materials, and organizers used to produce scarce goods. Like the more general society-wide condition of scarcity, a given resource falls into the scarce category because it has a limited availability in combination with greater (potentially unlimited) productive uses.
