Book excerpt: Industrial policy is making a comeback in the United States. It is more urgent than ever to understand how and whether industrial policy has worked to strengthen the US economy. This study analyzes and scores 18 US industrial policy episodes implemented between 1970 and 2020, in an effort to assess what went right and what went wrong—and how the current initiatives might fare.
