A timely investigation of the potential economic effects, both realized and unrealized, of artificial intelligence within the United States healthcare system. In sweeping conversations about the impact of artificial intelligence on many sectors of the economy, healthcare has received relatively little attention. Yet it seems unlikely that an industry that represents nearly one-fifth of the economy could escape the efficiency and cost-driven disruptions of AI. The Economics of Artificial Intelligence: Health Care Challenges brings together contributions from health economists, physicians, philosophers, and scholars in law, public health, and machine learning to identify the primary barriers to entry of AI in the healthcare sector. Across original papers and in wide-ranging responses, the contributors analyze barriers of four types: incentives, management, data availability, and regulation. They also suggest that AI has the potential to improve outcomes and lower costs. Understanding both the benefits of and barriers to AI adoption is essential for designing policies that will affect the evolution of the healthcare system.

The Brookings Papers on Economic Activity (BPEA) is a semi-annual academic conference and journal that pairs rigorous research with real-time policy analysis to address the most urgent economic challenges of the day. Working drafts of the papers are presented at the conference typically held twice each year. The final papers and discussant remarks from each conference are subsequently published in the journal several months later.

“Deep, informed, and reeks of common sense.” —Norman Ornstein “It is now beyond debate that rising inequality is not only leaving millions of Americans living on a sharp edge but also is threatening our democracy...For activists and scholars alike who are struggling to create a more equitable society, this is an essential read.” —David Gergen We are in an age of crisis. That much we can agree on. But a crisis of what, exactly? And how do we get out of it? In a follow up to their influential and much debated Death by a Thousand Cuts, Michael Graetz and Ian Shapiro focus on what really worries people: not what the rich are making or the government is taking from them but their own insecurity. Americans are worried about losing their jobs, their status, and the safety of their communities. They fear the wolf at the door. The solution is not protectionism or class warfare but better jobs, higher wages, greater protection for families suffering from unemployment, better health insurance, and higher quality childcare. And it turns out those goals are more achievable than you might think. The Wolf at the Door is one of those rare books that doesn’t just diagnose our problems, it shows how to address them. “This is a terrific book, original, erudite, and superbly well-informed, and full of new wisdom about what might and what might not help the majority of Americans who have not shared in our growing prosperity, but are left facing the wolf at the door...Everyone interested in public policy should read this book.” —Angus Deaton, Princeton University “Graetz and Shapiro wrestle with a fundamental question of our day: How do we address a system that makes too many Americans anxious that economic security is slipping out of reach? Their cogent call for sensible and achievable policies...should be read by progressives and conservatives alike.” —Jacob J. Lew, former Secretary of the Treasury
