Nobel laureate Solow shows how Kenneth J. Arrow's classic paper "The Economic Implications of Learning by Doing" fits into the modern theory of economic growth, and uses it as a springboard for a critical consideration of spectacular recent developments that have made growth theory a dynamic topic today.

Robert M. Solow is Emeritus Institute Professor of Economics at the Massachusetts Institute of Technology. He is the author of several books, most recently A Critical Essay in Modern Macroeconomic Theory (with F. Hahn).
