18. What Are the Major Advances in Growth Theory since Solow?
Chair Michael Spence, Philip H. Knight Professor Emeritus, Stanford University, and Recipient of the 2001 Nobel Memorial Prize in Economic Sciences, posed two questions for the speakers: What have we learned from the past 50 years of growth? What has been accomplished and what still needs to be done regarding economic development and growth in the modern world?. Daron Acemoglu, Professor of Applied Economics, Massachusetts Institute of Technology, noted that the richest nations today are 30 to 40 times as rich as the poorest. He asked why this is so, what can be done about it, and what the future holds. After noting Solow’s contributions, he identified two conceptual revolutions in economic thinking about growth and development process as a unity. He also identified a need for a more micro understanding of processes that lead to macro outcomes. Philippe Aghion, Professor, Department of Economics, Harvard University, used three endogenous growth paradigms developed in response to Solow to discuss aspects of growth policy. Audience questions provoked discussion on the product variety model, intervention with firms, and political power.
