Karl Shell (born May 10, 1938) is an American theoretical economist, specializing in macroeconomics and monetary economics.

Shell received an A.B. in mathematics from Princeton University in 1960. He earned his Ph.D. in economics in 1965 at Stanford University, where he studied under Nobel Prize in Economics winner Kenneth Arrow and Hirofumi Uzawa.

Shell is currently Robert Julius Thorne Professor of Economics at Cornell University (succeeding notable economist and airline deregulator Alfred E. Kahn in the Thorne chair). He previously served on the economics faculty at MIT and the University of Pennsylvania.

Shell has been editor of the Journal of Economic Theory, generally regarded as the leading journal in theoretical economics, since its inception in 1968.

While Shell has published academic articles on numerous topics in economics, he is primarily known for his contributions in three areas.

Between 1966 and 1973, Shell published three papers on inventive activity, increasing returns to scale, industrial organization, and economic growth. This contribution was important in its day, and later influenced the development of "new growth theory." Among others, Paul Romer cited and heavily built upon Shell's work in his seminal papers on endogenous growth theory.
