POINT ELASTICITY: The relatively responsiveness of a change in one variable (call it B) to an infinitesimally small change in another variable (call it A). The notion of point elasticity typically comes into play when discussing the elasticity at a specific point on a curve.< P>Point elasticity can be calculated in a number of different ways. Sophisticated economists, using sophisticated mathematical techniques (better known as calculus) can calculate point elasticity by taking derivatives of equations. Derivatives is fancy calculus talk for infinitesimally small changes.

VOLUNTARY EXCHANGE: The process of willingly trading one item for another. The emphasis here is on "willingly." Voluntary exchanges are the heart and soul of market transactions, and should be contrasted with the "involuntary" exchanges mandated by government taxes, laws, and regulations. While involuntary government-forced exchanges play an important role in a mixed economy, economists really, really like voluntary market exchanges because they promote economic efficiency.

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.
