ZERO SLOPE: A horizontal line in which the numerical value of the slope, calculated as the change in the variable on the vertical axis divided by a change in the variable on the horizontal axis, is zero. In other words, the Y-axis variable is fixed, or constant, for any and all values of the X-axis variable.

- At one end of the elasticity continuum is perfectly elastic:
- Perfectly elastic is an elasticity alternative in which infinitesimally small changes in one variable (price) cause infinitely large changes in another variable (quantity).
- 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 elastic demand and supply are represented by horizontal demand and supply curves.

ADVERSE SELECTION An inefficient, bad, or adverse outcome of a market exchange that results because buyers and/or sellers make decisions based on asymmetric information. This commonly results in a market that exchanges a lesser quality good, what is termed the market for lemons. Two related problems resulting from asymmetric information are moral hazard and the principal-agent problem. Two methods of lessoning the problem of adverse selection are signalling and screening.
