Outstanding. In a time when government action of any kind is ideologically suspect and entrepreneurship is undeniably glorified, the importance of this book cannot be overstated. According to popular belief, innovation should best be left to the dynamic entrepreneurs of the private sector, and the government should hold back. But what if all of that was wrong? What if the public sector, from Silicon Valley to medical breakthroughs, was the boldest and most valuable risk-taker of all? A brilliant book, Martin Wolf, Financial Times. One of the most insightful economics books in years, Jeff Madrick, New York Review of Books. Mazzucato is right to argue that the state has played a central role in creating groundbreaking innovations, Economist. Read her book. It will challenge your way of thinking, Forbes.
