Two hundred years ago, the first Industrial Revolution sparked a dramatic acceleration in the quantity of goods and services available to the average citizen--a trend of steadily increasing real income per capita that continues to this day. Since that time, economists have struggled to develop systematic explanations for what caused the sudden, rapid increase, why the economy keeps growing, and why the rate of growth varies in different time periods and nations. In this book, F. M. Scherer traces the evolution of economic growth theory from the Industrial Revolution to the present. Emphasizing technological change as the most crucial dynamic force for growth, Scherer analyzes early hypotheses that paid little attention to new technologies, follows the emergence of theories that increasingly emphasized technological change, and reviews the current state of economic growth theory. Pointing out a lack of solid microbehavioral foundations to support contemporary ""new growth"" ideas, Scherer then supplies some foundational ""bricks"" concerning financial investment and human capital, and concludes by exploring the prospects for sustaining rapid growth into the next century.
