About the Author of Mine!

Michael A. Heller and James Salzman, the acclaimed legal scholars and authors of Mine! How the Hidden Rules of Ownership Control Our Lives, are renowned experts in property rights and ownership design.

Heller, the Lawrence A. Wien Professor of Real Estate Law at Columbia Law School, and Salzman, the Donald Bren Distinguished Professor of Environmental Law at UCLA, combine decades of academic rigor with real-world relevance. Their book—a blend of law, economics, and behavioral psychology—explores how societal rules shape ownership conflicts, from airline seat reclining to digital privacy battles.

Heller’s prior work, The Gridlock Economy, examines how fragmented ownership stifles innovation, while Salzman’s Drinking Water: A History reveals the hidden systems behind a vital resource. Both have lectured globally, appeared on platforms like EconTalk, and delivered TED-style talks dissecting ownership’s role in climate change and wealth inequality.

Mine! has been praised by Publishers Weekly for its “intriguing legal cases and historical lessons,” with Cass R. Sunstein calling it “original and compelling.” Featured in major media and academic curricula, the book reframes everyday ownership disputes through six universal stories—a framework now cited in debates on inequality and corporate power.

FAQs About Mine!

What is Mine! by Michael A. Heller about?

Mine! explores the invisible social rules governing ownership through real-world examples like airplane seat reclining disputes and HBO password sharing. Law professors Heller and Salzman argue ownership isn’t fixed but a choice shaped by six narratives we unconsciously follow. The book blends legal theory, behavioral economics, and pop culture to reveal how "mine" shapes wealth distribution, digital privacy, and climate policy.

Who should read Mine! by Michael Heller and James Salzman?

This book suits law students studying property rights, pop culture enthusiasts analyzing everyday conflicts, and readers of Freakonomics or Nudge seeking actionable insights. Its accessible storytelling appeals to anyone curious about why we claim parking spots with chairs or accept plagiarism norms but not recipe knockoffs.

What are the six hidden rules of ownership described in Mine!?

Heller and Salzman identify six ownership narratives:

• First come (dibs on seats)
• Possession (physical control)
• Labor (earning through effort)
• Attachment (emotional ties)
• Self-ownership (body autonomy)
• Government allocation (legal mandates) These frameworks determine disputes over vaccine appointments, reclining seats, and Native American land rights.

How does Mine! explain the airplane seat reclining debate?

The authors frame reclining as a clash between possession (your seat’s mechanical control) and labor (the passenger behind you working). Airlines avoid taking sides, letting social norms decide—a microcosm of how ownership rules remain intentionally vague to accommodate competing claims.

Why does HBO allow password sharing according to Mine!?

HBO tacitly permits sharing to hook viewers on shows, prioritizing attachment (emotional investment in characters) over strict possession. This strategic ambiguity boosts long-term subscriptions despite short-term revenue loss.

What criticisms does Mine! receive in reviews?

Critics praise its engaging style but note it oversimplifies systemic issues like wealth inequality. The Kenyon Review highlights its limited exploration of power imbalances in ownership rule-making, though it acknowledges the book’s actionable framework for personal disputes.

How does Mine! apply to climate change?

The authors argue carbon emissions exemplify failed government allocation rules. By reframing atmospheric ownership via labor (countries reducing emissions deserve credit) or attachment (indigenous stewardship), societies can redesign incentive structures.

What credentials do Michael Heller and James Salzman bring to Mine!?

Heller, a Columbia real estate law professor, wrote The Gridlock Economy. Salzman, a UCLA environmental law expert, authored Drinking Water. Their combined expertise in property rights and resource management grounds the book’s case studies.

How does Mine! differ from other pop economics books?

Unlike Freakonomics, it focuses solely on ownership’s social scaffolding rather than broad behavioral economics. The book offers tangible conflict-resolution tools, like choosing between competing ownership narratives during negotiations.

Can you reclaim a parking spot with a chair, according to Mine!?

In Chicago, first come norms honor chair-held spots after snowstorms. New Yorkers reject this, prioritizing labor (shoveling) or possession (continuous occupancy). The authors show how local culture dictates which ownership story prevails.

Why is Mine! relevant in 2025?

With debates over AI copyright, geoengineering rights, and micro-apartment ownership intensifying, the book’s framework helps readers navigate emerging "mine" conflicts in tech and urban policy.

What quote encapsulates Mine!’s central thesis?

“Ownership isn’t a fact—it’s a story we choose to tell.” The authors emphasize that recognizing this empowers individuals to rewrite unfair rules in daily life and policy.
