[A] remarkably wise and perceptive collection of essays… [Nelson] provides an accessible introduction to growth theory. In unraveling the mystery of economic growth, Nelson argues that the keys are usually the things that the standard economic models leave out or take for granted: history, corporate cultures and political institutions. At the center of it is innovation, new technology, new ways of doing business—and how these ideas are dispersed through a firm, from one firm to another, from one country to another… Nelson resists the allure of simple formulas or sweeping prescriptions, sticking to his fundamental observation that growth is a dynamic process that takes many different forms and results from the interplay of lots of different factors.
