The 2020 Global Award for Entrepreneurship Research has been awarded to Professor John Haltiwanger. John Haltiwanger has made significant contributions to the field of entrepreneurship by improving our understanding of job creation and destruction, productivity growth, and the role of small- and medium-sized firms (SMEs) in economic development. He has played a major role in the careful development of large, longitudinal firm-level datasets, and introduced a novel and widely adopted measure of firm growth that addresses previous statistical biases. His work has influenced public policy and national statistical offices around the world.
