Macroeconomics activity and demand/Fluctuations in GDP

Occasional need for government intervention
Many consider the federal government to be a lender of last resort. The Great Depression is partly the consequence of many factors including, but not limited to, common thinking in the 1920s that government has no role in managing the economy, the absence of a division of the economy into microeconomics and macroeconomics, and the lack of awareness that equilibrium can occur alongside unemployment and business cycles.
