AmosWEB means Economics with a Touch of Whimsy!

A POSTERIORI: A conclusion reached through logical reasoning based on facts and observations about the real world. This notion is closely related to the scientific verification of hypotheses and the identification of principles. A similar sounding, but opposite term is a prior, which is a unverified presumption made before an analysis is undertaken. For example, in the study of economics of crime you might assume, a priori, that people are basically "good", and conclude, a posteriori, that people are more likely to commit crimes when the threat of capture and conviction is lower.

Lesson 4: Production Possibilities | Unit 3: The Curve Page: 9 of 24

Topic: Plot <=PAGE BACK | PAGE NEXT=>

We can transform the schedule of production possibility numbers into a graph.
  • Each bundle can be represented by a point in two dimensional production possibilities space.
  • The two dimensions of the space are clock calibrators on the horizontal axis and jogging shoes on the vertical axis.
  • The horizontal axis is measured between 0 and 11 calibrators.
  • The vertical axis is measured between 0 and 500 jogging shoes.
  • The two axis are joined at the origin.
  • The plotted bundles form a semi-circle pattern.
  • If these were stars in the night sky we might name it the arc of production. But it's not, so we won't.

MARGINAL UTILITY AND DEMAND

An explanation of the law of demand and the negatively-sloped demand curve based on utility analysis and the law of diminishing marginal utility. The law of diminishing marginal utility states that marginal utility declines as consumption increases. Because demand price depends on the marginal utility obtained from a good, price also declines as consumption increases, meaning price and quantity demanded are inversely related, which is the law of demand.

[What's This?]

Today, you are likely to spend a great deal of time looking for the new strip mall out on the highway looking to buy either a birthday gift for your aunt or a pair of leather sandals that won't cause blisters. Be on the lookout for florescent light bulbs that hum folk songs from the sixties.

This isn't me! What am I?
