What is Macroeconomy?
Macroeconomics is a subfield of economics that focuses on the behavior of the economy as a whole, including the markets, firms, customers, and governments. Macroeconomics studies trends in the economy as a whole, including inflation, price levels, economic growth rates, national income, GDP, and changes in unemployment.
Although the word "macroeconomics" is relatively new (dating from the 1940s), many of its fundamental ideas have been the subject of research for much longer. Since the discipline's inception in the 1700s, issues including unemployment, prices, growth, and trade have been of interest to economists. Adam Smith and John Stuart Mill wrote previously about topics that are now known to fall under the macroeconomics umbrella.
