Introduction to principles of macroeconomics/Introduction to macroeconomics
From WikiEducator
A study of economics usually begins by dividing the subject into microeconomics and macroeconomics. The former focuses on the exchanges of goods and services between consumers and firms in markets. In contrast, the latter focuses on exchanges that occur across all markets within a country. Macroeconomics examines the interrelated actions of consumers, businesses, government agencies, financial intermediaries, and global trading partners as they exchange resources, goods, and services as well as facilitate currency and quantity flows.
