Chapter Summary

There is a circular flow of spending in the economy in which households supply resources in resource markets.  Businesses demand resources to produce goods and services which they sell in product markets to households.  In an economy without any leakages or injections, total spending will equal total output and there never would be any unemployment.

Leakages from the spending stream include savings, taxes and imports.  Injections include investment spending, government spending and exports.  When leakages equal injections, total spending will equal total output and the macroeconomy will be in equilibrium.  If leakages exceed injections, then total output exceeds total spending and the level of national output (GDP) will fall.  If injections exceeds leakages, then total spending exceeds total output and the level of national output will rise. Equilibrium may be reached at a level of GDP in which there is unemployment.  If there is too much spending, GDP may reach equilibrium at a level in which there is inflation.

Economic policy is used to affect the levels of output, employment, and prices in the economy.  There are two types of demand management policies: fiscal policy and monetary policy. Fiscal policy is conducted by Congress and the President and involves changes in government spending and/or taxes.  In a recession, government spending is raised and taxes are lowered.  Both lead to more spending in the economy and help to increase GDP.  In an inflation, government spending is decreased and taxes are increased in an attempt to reduce spending in the economy. Monetary policy is conducted by the Federal Reserve System.  The money supply is increased in a recession and reduced in an inflation.
