Using a mixed-methods approach, Charles R. Hankla draws upon archival research and interviews from France and India as well as quantitative models of sixteen countries across six decades. He finds that when state and private actors are aligned in their institutional structures, which can happen in both corporatist and pluralist systems, industrial policy tends to be more effective. It is when the state or the private sector independently dominates industrial policy that poor outcomes are most likely. As In Pursuit of Prosperity shows, rather than being fixed characteristics of countries, policymaking styles vary across time and across sectors of the economy, reflecting the changing power dynamics and organizational resources of stakeholders. The book sheds light on how industrial policy--which is experiencing a comeback in the United States and beyond--can best be harnessed for upgrading. It offers a valuable contribution to our understanding of the complex relationship between state politics and economic performance in the modern globalized world.
