What is Macroeconomics? Macroeconomicsis the study of issues that affect the economy as a whole. Examples are the effects of inflation, and unemployment on economic growth and economic well-being.
Divisions of Macroeconomics • The scienceof macroeconomics is positive economics: the study of economic facts and theories and how they work. • Policy practice of macroeconomics is concerned with policies to achieve goals.
Normative Macroeconomic Goals • High growth • Avoiding large swings in economic output • Low unemployment • Low inflation • Low income inequality • No poverty
Why These Goals? • High growth • Avoiding large swings in economic output • Low unemployment • Low inflation • Income distribution • Poverty
Normative Economic Goals • Economic policy is dependent on normative economic goals. • Political processes determine which goals have the highest priority. • Once priority has been established, macroeconomics deals with the ways to achieve those goals

Goals: Unemployment • The unemployment rate is the percentage of the labor force looking for work, but unable to find it.
U.S. Unemployment Each one-point increase in the unemployment rate is associated with: • 920 more suicides • 650 more homicides • 4000 more people admitted to state mental institutions • 3300 more people sent to state prisons • 37,000 more deaths • Increases in domestic violence and homelessness
Goals: Inflation • Inflation is the continual increase in the average price of goods and services. • Inflation usually increases as actual output rises above potential output and usually decreases if output falls below potential output. • Policymakers may face a trade-off between high inflation and low unemployment.
