LONG-RUN MARGINAL COST CURVE: A graphical representation of the relationship between long-run marginal cost and the quantity of output produced. Like other marginal curves, the long-run marginal cost curve follows the average-marginal rule relative to the long-run average cost curve. In all outward appearance, the long-run marginal cost curve looks very much like the short-run marginal cost, that is, it is U-shaped. However, the U-shape is attributable to returns to scale rather than increasing and decreasing marginal returns.

Getting Your Share Of FARM SUBSIDIES

Our pedestrian excursion through the economy has helped me work up a ferocious appetite. I vote for a quick stop at the Mr. Market Super Food Discount Store where we can purchase a loaf of bread, assorted meats, and some cheese -- all for a luncheon tribute to the Earl of Sandwich. While a self-made tribute to the Earl is less expensive than any purchased from Manny Mustard's House of Sandwich, the ingredients from Mr. Market Super Food Discount Store still carry a hefty price tag. If you're hungry and have limited cash on hand, you might wonder whether food prices are higher than they need to be.

[What's This?]

Today, you are likely to spend a great deal of time wandering around the shopping mall hoping to buy either a birthday greeting card for your grandfather or a weathervane with a cow on top. Be on the lookout for empty parking spaces that appear to be near the entrance to a store.
