Messy Jobs: The Work That AI Cannot Reach
Messy Jobs, by economists Luis Garicano, Jin Li, and Yanhui Wu, argues that AI will not automate most white-collar work because many jobs are inherently 'messy' — involving coordination, negotiation, and human interactions. The authors use economic reasoning to show that as intelligence becomes cheap, judgment, coordination, trust, and responsibility become more valuable. The book features endorsements from notable economists and business leaders.

From the Authors
Imagine you wake up to a message from your AI agent: “Good news. I changed your internet provider and cut your bill by 10 percent. I also found, booked, and paid for a summer house that fits your needs.” Now think about what happens next. You may live with a partner who has already changed the plans you agreed on last night, or with flatmates who didn’t do the dishes, or with children who have decided this morning that they are not going to their swimming lessons anymore. In all cases you are the manager of a tiny, fast-moving organization — deciding how to allocate scarce resources, figuring out the division of labor, and negotiating agreements. The bottleneck is not information. It is the politics of the household: making sure decisions are acceptable to everyone and implemented. Your family life, like everyone else’s, can be a mess.
All knowledge work varies along the same dimension: messiness. On one end, there is one defined task to execute — you get the payslips via email, use rules to fill out a form, and get a result. On the other end, there is a wide bundle of complex tasks: running a factory, or a family, involves work that is very hard to specify in advance and full of conflict. Along the messiness spectrum, AI has a different ability to help or replace humans. While it is easy for AI to replace simple, clean tasks, it is hard for it to replace messy jobs.
In February 2026, the head of Microsoft’s AI division told the Financial Times that most white-collar tasks could be “fully automated by an AI within the next twelve to eighteen months.” We believe these predictions are wrong. Not because we believe AI is weak. But because the people making the predictions do not understand what most white-collar workers do all day.
The future is not shaped by technology alone. Understanding the consequences of AI requires economic reasoning about scarcity, about complementarities and bottlenecks, about signaling and incentives, and about the organization of work. These are the concepts we use. Our specific examples will age — these concepts will not.

In Messy Jobs, Garicano, Li, and Wu bring the discipline of organizational economics to a question too often left to speculation: How will AI actually reshape work? They move past the usual debates about what AI can or cannot do and ask the harder questions. What shapes the incentives to adopt it? How does adoption reshape the incentives to learn? What new configuration of skills will emerge as AI advances? A rigorous, original, and engaging account of how AI will reshape organizations and labor markets, and what it will take to thrive in them.

Messy Jobs is a brilliant application of price theory. AI changes what is scarce in the economy, and therefore what is valuable. When intelligence becomes cheap, judgment, coordination, trust, and responsibility become more valuable. The authors use this simple, powerful logic to illuminate how AI will reshape work and organizations.

This is simply a must-read book if you are interested in the future of work in the age of AI. For decades, Luis Garicano has been a leading voice in how organizations morph and change with new technology and innovation. Together with Jin Li and Yanhui Wu, they have written the definitive text on how AI will affect the labor market. The book is an impressive feat of combining academic rigor with clear explanations and concrete examples. I would recommend this book to anyone interested in learning about what comes next.

This is the first book in the AI era that recognizes that most of what organizations struggle with does not involve computational problems. People in messy jobs must hold coalitions together, adjudicate between competing interests, and make change stick. These are political, diplomatic, and interpersonal challenges. As a result, these types of messy jobs will persist well into our AI future. Garicano, Li, and Wu are neither techno-utopian nor techno-dystopian. They take seriously what machines can do, what humans will do, and how jobs will be rebundled. The economics analysis is lucid and penetrating, and the book pinpoints where human agency will remain paramount. The book is hopeful and practical for anyone charting a career in the coming decade.

AI is not going to lead to mass unemployment, and this is the best book to explain why not. It also illuminates how labor markets are likely to evolve. It is short, to the point, eminently readable, and of extreme relevance.

There is a lot of woolly thinking on the topic of AI and jobs. This excellent book contains by far the most thoughtful and economically literate account that has yet been written.

This book isn't just some economist's armchair theorizing; it's a practical guide. I hope you get as much out of it as I did.

“The world is not running out of problems that need solutions.
If you bring judgment, determination, and the willingness to be held responsible for unpredictable outcomes — you will not be replaced.
You will be needed more than ever.”
