This book celebrates the contributions of David B. Audretsch, Distinguished Professor at the School of Public and Environment Affairs (SPEA) at Indiana University (USA), co-founder and co-editor of Small Business Economics, and former Director of the Entrepreneurship, Growth and Public Policy Group at the erstwhile Max Planck Institute of Economics (Jena, Germany). For his pioneering work, which explores the links between entrepreneurship, government policy, innovation, economic development, and global competitiveness, he has received the 2001 Global Award for Entrepreneurship Research from the Swedish Foundation for Small Business Research and the 2011 Schumpeter Prize from the University of Wuppertal (Germany). This volume features original contributions from over 50 leading scholars to map, analyze and evaluate the impact of Audretsch research on a broad spectrum of research fields, ranging from economics to entrepreneurship and geography. The development and evolution of key ideas which have significantly shaped theory and future research across these fields are also explored.
