It is increasingly understood that entrepreneurship plays a critical role in economic growth and well-being. But which policies can governments develop to release its benefits? This publication offers guidance and inspiration. It identifies the range of entrepreneurship policies being pursued internationally, the problems the policies seek to solve and how they are designed and implemented. The focus is on how to create a broad base of start-ups with the potential for sustainability and growth by building a pipeline of new entrepreneurs, supporting start-ups to overcome barriers in areas such as skills, finance and innovation and stimulating vibrant entrepreneurial ecosystems. The publication examines the rationale for entrepreneurship policy, presents a typology of policy approaches and highlights principles for policy success. The points are illustrated by 16 case studies of inspiring practice policies from 12 OECD countries. These cases span policies for regulations and taxation, entrepreneurship education and training, advice and coaching, access to finance, internationalisation, innovation, and holistic packages for ecosystem building. Helpful summary tables guide readers to the information that will respond to their questions. The publication will give readers an overview of key entrepreneurship policy interventions and tips on entrepreneurship policy success.
