SERVICES: Activities that provide direct satisfaction of wants and needs without the production of tangible products or goods. Examples include information, entertainment, and education. This term service should be contrasted with the term good, which involves the satisfaction of wants and needs with tangible items. You're likely to see the plural combination of these two into a single phrase, "goods and services," to indicate the wide assortment of economic production from the economy's scarce resources.

- At the other end of the elasticity continuum is perfectly inelastic:
- Perfectly inelastic is an elasticity alternative in which an infinitely large change in one variable (price) is needed to cause an infinitesimally small change in another variable (quantity).
- Once again, this works for both the price elasticity of demand and the price elasticity of supply, because the negative value of the price elasticity of demand is ignored.
- Perfectly inelastic demand and supply are represented by vertical demand and supply curves.

Of course, these are only estimates because such activity, by definition, goes unreported. If activity in the underground economy is added to official activity in the "overground" economy, then gross domestic product could be boosted by as much as 25 percent to 50 percent, or more. Inclusion of employment in the underground economy is also likely reduce the official unemployment rate by a few percentage points.
