LAW OF DIMINISHING MARGINAL UTILITY: The principle stating that as more of a good is consumed, eventually each additional unit of the good provides less additional utility--that is, marginal utility decreases. Each subsequent unit of a good is valued less than the previous one. The law of diminishing marginal utility helps explain the negative slope of the demand curve and the law of demand.

Topic: Two Runs: Short And Long <=PAGE BACK | PAGE NEXT=>

  • The two key time production periods.

  • The short run is a production time period in which at least one input is variable and at least one input is fixed.
  • The key is that firms produce and supply output on a day-to-day basis by adding variable inputs to fixed inputs.

  • The long run is a production time period in which all inputs are variable.
  • The long run is a period long enough to alter the quantities of ALL inputs, especially changing the amount of capital or the size of a factory.

LONG-RUN INDUSTRY SUPPLY CURVE

The relation between market price and the quantity supplied by all firms in a perfectly competitive industry after the industry has completed its long-run adjustment. The long-run industry supply curve effectively traces out a series of equilibrium prices and quantities that reflect long-run adjustments of a perfectly competitive industry to demand shocks. This long-run adjustment can take one of three paths, indicating an increasing-cost industry, a decreasing-cost industry, and a constant-cost industry.
