An econometric analysis of the role of knowledge in economic performance

We conduct a regression analysis of the effects of knowledge on aggregate economic performance using data from the United Nations Development Program (UNDP) and the World Bank for four groups of countries during 1995-2001. Our results indicate that knowledge is a key driver of economic growth for each group of countries. More importantly, we find that variation in economic performance among these groups may be related to the timing of investment in education, R&D, and information technology, as well as economic policies that affect trade and foreign direct investment. © Springer Science + Business Media, Inc. 2006.
