LUXURY GOOD: In general, a good (or service) that is not essential but makes like more enjoyable. Luxury goods are often more expensive and primarily purchased by people with more wealth and income. Using more precise, technical language, a luxury good exists if the income elasticity of demand is positive and greater than one. In other words, as people receive more income, they devote an increasingly larger share of income to the purchase of luxury goods.

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.

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.
