He coined a number of new words including econometrics and macroeconomics. He helped set up Neo-Walrasian research. He formalized production theory. In econometrics he worked on time series and linear regression analysis. With Frederick Waugh, he introduced the celebrated Frisch-Waugh theorem (Econometrica1933) (sometimes referred to as the Frisch-Waugh-Lovell theorem). His 1933 work on impulse-propagation business cycles became one of the principles of modern New Classical business cycle theory.
