Macroeconomics, like microeconomics before, is much more simple than it sounds. While microeconomics dealt with economic decisions on an individual level, macroeconomics applies the same economic principles to an entire society. Essentially, we’re switching from a business class to a social studies class. (If microeconomics were psychology, then macroeconomics would be sociology). Macroeconomics focuses on national issues like taxes, unemployment, inflation, the banking system, the printing of money, etc. If you’ve ever wondered why gas prices keep changing, a dollar bill is worth less than it was yesterday, or how the government bailout of companies like AIG or GM affects you, than you’ll enjoy a quick study of macroeconomics.
