RIVAL CONSUMPTION: Consumption of a good by one person imposes a cost on, or prevents consumption of the good by, another person. Some goods, like food, have extremely rival consumption. One person, and only one person, gets the benefit. Other goods, like national defense, have no consumption rivalry, everyone can benefit simultaneously without imposing a cost on others. This is one of the two key characteristics of a good (the other is excludability) that distinguishes between common-property goods, near-public goods, private goods, and public goods.

ASSUMPTIONS, KEYNESIAN ECONOMICS The macroeconomic study of Keynesian economics relies on three key assumptions--rigid prices, effective demand, and savings-investment determinants.

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.
