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.

Why Study: Price Controls
|
|
|
- Price controls take one of two forms -- price ceiling and price floor:
- A price ceiling is a legally mandated maximum price imposed on a market. Buyers and sellers are prevented from exchanging the good at any price above the legal maximum.
- A price floor is a legally mandated minimum price imposed on a market. Buyers and sellers are prevented from exchanging the good at any price below the legal minimum.
- Both types of price controls tend to be more effective for inelastic demand and supply

AVERAGE FIXED COST Total fixed cost per unit of output, found by dividing total fixed cost by the quantity of output. When compared with price (per unit revenue), average fixed cost (AFC) indicates whether or not a profit-maximizing firm should shutdown production in the short run. Average fixed cost is one of three average cost concepts important to short-run production analysis. The other two are average total cost and average variable cost. A related concept is marginal cost.
