Macro-EconomicsThe Big Picture
Macroeconomics is the study of the large economy as a whole. It is the study of the big picture.
• Instead of analyzing one consumer, we analyze everyone. • Instead of one business we study all businesses.
What is Macroeconomics?
Why study the whole economy?• The field of macroeconomics was born during
the Great Depression. • Government didn’t understand how to fix a depressed economy with 25% unemployment.
• Macro was created to:1. Measure the health of the whole economy.2. Guide government policies to fix problems.

The Three Goals of Macro Economic Policy
• Economic Growth:– Is the economy increasing its capability to
produce more goods and services?• Full-Employment:
– Is the economy providing jobs for those who want to be employed?
• Price Stability:– Prices are signals that help us coordinate the
resources of the economy. In order to be most efficient we must get clear and dependable signals. Without price stability, consumers and producers are less likely to make good decisions that will benefit the overall economy.
