Lawrence Klein

Lawrence Klein developed large-scale econometric models used to mathematically analyze national economies and forecast economic fluctuations. He was awarded the 1980 Nobel Memorial Prize in Economic Sciences for creating these computerized models. His work allowed governments to estimate the likely macroeconomic effects of specific public policies.

The Wharton Econometric Forecasting Model, developed by Lawrence Klein and his colleagues at the University of Pennsylvania, was a pioneering economic tool used to predict macroeconomic trends. It became a standard commercial product used by major corporations and government agencies. It helped launch the modern industry of macroeconomic data forecasting.

Yes, before establishing the Wharton models, Lawrence Klein spearheaded the creation of the Brookings Quarterly Econometric Model in the early 1960s. This massive collaborative project was sponsored by the Brookings Institution and involved dozens of economists. It was designed to be the first highly detailed, mathematical simulation of the entire United States economy.

Lawrence Klein's early econometric work was heavily influenced by the Keynesian macroeconomic framework. His very first book, "The Keynesian Revolution" published in 1947, sought to formalize John Maynard Keynes's theories into testable mathematical equations. He spent his career proving that Keynesian models could accurately predict economic behavior.
