Topic: Inefficiency <=PAGE BACK | PAGE NEXT=>

Inefficient use of resources can result from:
  • The fourth rule of competition-with less competition buyers or sellers control the price. The quantity is too little and the demand price is greater than the supply price.
  • The seventh rule of complexity-costs or benefits external to the market (externalities) cause differences between the value of goods produced and goods not produced, even though market demand and supply prices are equal.
  • The fifth rule of imperfection-markets are not perfect.
    • Scarcity implies the lack of competition.
    • Complexity implies externalities.
Efficiency is a goal, not a perpetual state of the world.

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.
