QUASI-PUBLIC GOOD: A good that is easy to keep nonpayers from consuming, but use of the good by one person does not prevent use by others. Also termed a near-public good,the trick with a quasi-public good is that it is easy to keep people away, and thus you can charge them a price for consuming, but there is no real good reason to do so. From an efficiency view, the more people who consume a quasi-public good, the better off society. This mixture of nearly unlimited benefits and the ability to charge a price means that some quasi-public goods are sold through markets and others are provided by government. For efficiency's sake, none should be sold through markets.

KEYNESIAN MODEL A macroeconomic model based on the principles of Keynesian economics that is used to identify the equilibrium level of, and analyze disruptions to, aggregate production and income. This model identifies equilibrium aggregate production and income as the intersection of the aggregate expenditures line and the 45-degree line. The Keynesian model comes in three basic variations designated by the number of macroeconomic sectors included--two-sector, three-sector, and four sector. The Keynesian model is also commonly presented in the form of injections and leakages in addition to the standard aggregate expenditures format. This model is used to analyze several important topics and issues, including multipliers, business cycles, fiscal policy, and monetary policy.
