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.

ASSUMPTIONS, KEYNESIAN ECONOMICS The macroeconomic study of Keynesian economics relies on three key assumptions--rigid prices, effective demand, and savings-investment determinants. First, rigid or inflexible prices prevent some markets from achieving equilibrium in the short run. Second, effective demand means that consumption expenditures are based on actual income, not full employment or equilibrium income. Lastly, important savings and investment determinants include income, expectations, and other influences beyond the interest rate. These three assumptions imply that the economy can achieve a short-run equilibrium at less than full-employment production.
