A comprehensive, rigorous, and up-to-date introduction to growth economics that presents all the major growth paradigms and shows how they can be used to analyze the growth process and growth policy design.

This comprehensive introduction to economic growth presents the main facts and puzzles about growth, proposes simple methods and models needed to explain these facts, acquaints the reader with the most recent theoretical and empirical developments, and provides tools with which to analyze policy design. The treatment of growth theory is fully accessible to students with a background no more advanced than elementary calculus and probability theory; the reader need not master all the subtleties of dynamic programming and stochastic processes to learn what is essential about such issues as cross-country convergence, the effects of financial development on growth, and the consequences of globalization. The book, which grew out of courses taught by the authors at Harvard and Brown universities, can be used both by advanced undergraduate and graduate students, and as a reference for professional economists in government or international financial organizations.

The Economics of Growth first presents the main growth paradigms: the neoclassical model, the AK model, Romer's product variety model, and the Schumpeterian model. The text then builds on the main paradigms to shed light on the dynamic process of growth and development, discussing such topics as club convergence, directed technical change, the transition from Malthusian stagnation to sustained growth, general purpose technologies, and the recent debate over institutions versus human capital as the primary factor in cross-country income differences. Finally, the book focuses on growth policies—analyzing the effects of liberalizing market competition and entry, education policy, trade liberalization, environmental and resource constraints, and stabilization policy—and the methodology of growth policy design. All chapters include literature reviews and problem sets. An appendix covers basic concepts of econometrics.


Advanced economies have experienced a tremendous increase in material well- being since the industrial revolution. Modern innovations such as personal computers, laser surgery, jet airplanes, and satellite communication have made us rich and transformed the way we live and work. But technological change has also brought with it a variety of social problems. It has been blamed at various times for increasing wage and income inequality, unemployment, obsolescence of physical and human capital, environmental deterioration, and prolonged recessions.To understand the contradictory effects of technological change on the economy, one must delve into structural details of the innovation process to analyze how laws, institutions, customs, and regulations affect peoples' incentive and ability to create new knowledge and profit from it. To show how this can be done, Philippe Aghion and Peter Howitt make use of Schumpeter's concept of creative destruction, the competitive process whereby entrepreneurs constantly seek new ideas that will render their rivals' ideas obsolete.Whereas other books on endogenous growth stress a particular aspect, such as trade or convergence, this book provides a comprehensive survey of the theoretical and empirical debates raised by modern growth theory.
It develops a powerful engine of analysis that sheds light not only on economic growth per se, but on the many other phenomena that interact with growth, such as inequality, unemployment, capital accumulation, education, competition, natural resources, international trade, economic cycles, and public policy.
