Ragnar Frisch is a Norwegian economist who first introduced the terms "microeconomics" and "macroeconomics" in 1933.
Microeconomics: Focuses on the actions of individuals and industries. For example, it studies the effects of minimum wages, taxes, and monopolies on individual markets.
Macroeconomics: Studies the behavior of an economy as a whole. For example, it studies the effect of monetary and fiscal policy on the economy as a whole, rather than on a specific individual or industry.
Frisch was also a co-recipient of the first Nobel Memorial Prize in Economic Sciences in 1969.
