BUDGET PROPORTION: One of three elasticity determinants (time period and substitute availability are the other two) stating that the elasticity of a good tends to be greater when the proportion of the budget devoting to the good is greater. In other words, the price elasticity of demand for housing (which takes up a sizeable portion of most budgets) is greater than that for a pair of socks (which does not take up much of most budgets). Even small percentage changes in goods that constitute a sizeable share of income can be quite large in absolute terms. As such, buyers tend to more sensitive to price changes in big-budget expenditures. This elasticity determinant works primarily for the price elasticity of demand.

EXTERNALITIES: Costs or benefits that are not included in the market price of a good because they are not included in the supply price or the demand price. Pollution is an example of an externality cost if producers aren't the ones who suffer from pollution damages. Education is an example of an externality benefit when members of society other than students benefit from a more educated population. Externality is one type of market failure that causes inefficiency.

[What's This?]

Today, you are likely to spend a great deal of time watching infomercials trying to buy either a package of 3 by 5 index cards, the ones without lines or a blue mechanical pencil. Be on the lookout for telephone calls from former employers.
