A PRIORI: A presumption made before an analysis is undertaken, often based on experiences, beliefs, or deductions from seemingly self-evident propositions about how the world works. This is a Latin for assumption or axiom. A similar sounding, but opposite term is a posteriori, which is derived from observation or facts. For example, in the study of economics of crime you might assume, a priori, that people are basically "good", because that just seems to be part of human nature, and conclude, a posteriori, that people are more likely to commit crimes when the threat of capture and conviction is lower.

EFFECTIVE DEMAND: The notion that the actual demand for aggregate output in the macroeconomy is based on the actual income or other existing economic conditions and not on income and conditions existing in equilibrium. The idea of effective demand plays a key role in Keynesian economics and how the macroeconomy can have extended periods of unemployment. Effective demand is in direct contrast to the view underlying classical economics that demand is that existing in equilibrium.

MARKET CONTROL

The ability of buyers or sellers to exert influence over the price or quantity of a good, service, or commodity exchanged in a market. Market control largely depends on the number of competitors on each side of the market. If a market has relatively few buyers, but many sellers, then limited competition on the demand-side of the market means buyers tend to have relatively more market control than sellers. The converse occurs if a market has many buyers, but relatively few sellers. This is also termed market power.
