Traditional growth theory emphasizes the incentives for capital accumulation rather than technological progress. Innovation is treated as an exogenous process or a by-product of investment in machinery and equipment. Grossman and Helpman develop a unique approach in which innovation is viewed as a deliberate outgrowth of investments in industrial research by forward-looking, profit-seeking agents.

Gene Grossman and Elhanan Helpman are widely acclaimed for their pioneering theoretical studies of how special interest groups seek to influence the policymaking process in democratic societies. This collection of eight of their previously published articles is a companion to their recent monograph, Special Interest Politics. It clarifies the origins of some of the key ideas in their monograph and shows how their methods can be used to illuminate policymaking in a critical area.

Why are some societies but not others able to encourage investments in places, people, and productivity?

The answer, the book argues, lies to a large extent in institutional differences across societies. Such institutions are wide-ranging and include formal constitutional arrangements, the role of economic and...

The Organization of Firms in a Global Economy presents a new research program that is transforming the study of international trade.

It addresses such questions as why only a small proportion of firms in a given industry export and why an even smaller proportion invest abroad; why exporters tend to be more productive than nonexporters; why almost one-third of international trade takes place...

Far more than an intellectual puzzle for pundits, economists, and policymakers, economic growth--its makings and workings--is a subject that affects the well-being of billions of people around the globe. In The Mystery of Economic Growth, Elhanan Helpman discusses the vast research that has revolutionized understanding of this subject in recent years, and summarizes and explains its critical messages in clear, concise, and accessible terms.

The tale of growth economics, as Helpman tells it, is organized around a number of themes: the importance of the accumulation of physical...
