QUASI-PUBLIC GOOD: A good that is easy to keep nonpayers from consuming, but use of the good by one person does not prevent use by others. Also termed a near-public good,the trick with a quasi-public good is that it is easy to keep people away, and thus you can charge them a price for consuming, but there is no real good reason to do so. From an efficiency view, the more people who consume a quasi-public good, the better off society. This mixture of nearly unlimited benefits and the ability to charge a price means that some quasi-public goods are sold through markets and others are provided by government. For efficiency's sake, none should be sold through markets.

Topic: National Income <=PAGE BACK | PAGE NEXT=>

The first three related, but slightly different income measures is national income (NI), income earned by the factors of production.
  • National income is the sum of wages (W), interest (I), rent (R), profit (P) and proprietors' income (PI):

NI = W + I + R + P + PI

  • National income is also found by subtracting capital consumption allowance (CCA) and indirect business taxes (IBT) from, and adding net foreign factor income (NFFI) to, GDP:

NI = GDP - CCA - IBT + NFFI

  • And because NDP = GDP - CCA:

NI = NDP - IBT + NFFI

AVERAGE FACTOR COST AND MARGINAL FACTOR COST

A mathematical connection between average factor cost and marginal factor cost stating that the change in the average factor cost depends on a comparison between average factor cost and marginal factor cost. For perfect competition, with no market control, marginal factor cost is equal to average factor cost, and average factor cost does not change. For monopsony and other firms with market control, marginal factor cost is greater than average factor cost, and average factor cost rises.
