The terms microeconomics and macroeconomics were coined by Professor Ragnar Frisch of Oslo University for the first time in 1933 and since then they gained popularity and were widely used by other economists. Now they have become an integral part of economic terminology. Ragnar Anton Kittil Frisch was a Norwegian economist and the co-winner with Jan Tinbergen of the first Nobel Memorial Prize in Economic Sciences in 1969. Frisch was one of the founders of economics as a modern science. He made a number of significant advances in the field of economics and coined a number of new words.
