How Law Creates Capital: A Dialogue with Katharina Pistor

In the fall of 2020, on behalf of Zhejiang University International Business School's (ZIBS) "Meet the Author" lecture series, I invited Columbia Law School Professor Katharina Pistor for an in-depth dialogue. Professor Pistor is a pioneer in the study of law and capital. Her book The Code of Capital: How the Law Creates Wealth and Inequality (Princeton University Press) puts forward a groundbreaking argument: capital is not a naturally occurring economic resource, but rather a product of legal "coding" — it is the legal system that transforms ordinary assets into wealth-generating machines, and those who wield these coding tools are the fundamental beneficiaries of global inequality.

I. "The Code of Capital" — Law as the Invisible Architect of Wealth

At the outset of our dialogue, Professor Pistor opened with a fundamental question: What is capital? She noted that economists typically view capital as one of the factors of production — alongside labor and land. But this definition obscures a critical fact: whether the same piece of land, the same technology, or the same debt can become "capital" depends on whether law has endowed it with specific attributes.

Professor Pistor proposed four key legal attributes of capital — this was the most theoretically original framework presented during our entire conversation:

1. Priority — Law grants certain rights holders precedence over others. When multiple parties claim rights to the same asset, priority determines who gets paid first.
2. Durability — Law enables property rights to persist across time, even beyond the natural lifespan of the rights holder. Trust law provides the most classic example: assets are passed down through generations, shielded from the debts of individual heirs.
3. Universality — Law elevates what was originally an agreement between two parties into a right enforceable against the entire world (erga omnes). This means your property right is not merely a matter between you and your counterparty, but a legal fact that everyone must respect.
4. Convertibility — Law allows asset holders to convert their assets into safer forms during a crisis. This is particularly critical in financial crises: whether one can convert assets into cash or government bonds often determines the survival of wealth.

Professor Pistor's core insight is this: these four attributes are not inherent qualities of the assets themselves, but rather bestowed by the legal system. Whoever can mobilize legal tools to "code" their assets can transform ordinary assets into capital — and this is precisely the role of lawyers as "master coders of capital."^[1]

II. The Six Legal Modules: The Capital Coding Toolkit

Professor Pistor further elaborated on the six legal modules that enable capital coding, each of which serves as a core tool for transforming ordinary assets into wealth-generating machines:

1. Property Law — The oldest coding tool, granting holders exclusive control over assets. From the Enclosure Movement of the Middle Ages to colonial-era land registration, the history of property law is a history of wealth creation and distribution.
2. Collateral Law — Allows asset holders to pledge their property as security for borrowing, thereby leveraging legal protection for credit.
3. Trust Law — A unique invention of the common law tradition, separating the control of assets from the beneficial interest, creating an "asset pool" independent of any individual, enabling wealth to be transmitted across generations.
4. Corporate Law — Shapes enterprises as "legal persons," granting them assets independent of shareholders and achieving the separation of personal risk from business capital.
5. Bankruptcy Law — A law that ostensibly protects debtors but in reality provides institutional safeguards for capital's priority by establishing the order of creditor repayment.
6. Contract Law — The most flexible coding tool, allowing private parties to replicate and even surpass the functions of all the above legal modules through contractual arrangements.

The interplay of these six modules constitutes the legal infrastructure of modern capitalism. Professor Pistor illustrated this with a compelling example: how California home mortgages, through securitization — using layered combinations of trust law, corporate law, and contract law — are transformed from immovable physical assets into financial instruments traded on global markets, ultimately held by Chinese sovereign wealth funds or German regional banks.^[2]

III. The Empire of Legal Globalization: Why Anglo-American Lawyers Dominate World Capital

One of the most striking passages in our dialogue was Professor Pistor's analysis of legal globalization. She pointed out that virtually all of the top one hundred global law firms are British or American — and this is no coincidence.

The reason is that the "coding" of global capital primarily relies on two legal systems: English law and New York State law. London and New York are not merely global financial centers but also global "legal centers" — the governing law of international financial contracts overwhelmingly designates English law or New York law. This means that regardless of where the transacting parties are located, the legal architecture of capital is dominated by Anglo-American legal professionals.

Professor Pistor introduced a thought-provoking concept: this is not an "empire by law" but rather an "empire of law" — the Anglo-American legal system, through the expansion of global law firm networks, has achieved dominance over the rules governing global capital operations without the need for military or political force. Courts in various countries voluntarily recognize and enforce rights created under these legal systems, thereby extending the effectiveness of legal coding across national borders.^[3]

IV. The Legal Nature of Disruptive Innovation: The True Weapon of the Ubers of the World

During the discussion, I posed a question to Professor Pistor about the "disruptive innovation" of technology companies: firms like Uber and FinTech startups seem to always act first and comply later — how does this relate to the logic of legal coding?

Professor Pistor's response was incisive: what these companies are doing is essentially legal coding. She noted that Uber's core strategy is not technological innovation per se, but rather legal arbitrage — exploiting the flexibility of contract law to redefine what would otherwise be employment relationships governed by labor law as "independent contractor" relationships, thereby circumventing obligations such as minimum wage and social insurance.

"When they are small, regulators don't care. But once they grow large enough, they say: We are already here, and if you regulate us now, it will affect the livelihoods of millions." Professor Pistor pointed out that this is precisely the power logic of legal coding: first create a fait accompli, then leverage the social impact of that fact to resist legal constraints.

This analysis gave me a profound realization: in discussions about fintech regulation, we cannot think solely from a technological perspective; we must also understand the legal coding strategies behind emerging business models — which is precisely the core theme I have been exploring in joint executive education programs at Cambridge and Zhejiang University.^[4]

V. Common Law vs. Civil Law: Capital Coding Capacity Across Two Legal Traditions

I further asked Professor Pistor: is there a systematic difference in capital coding capacity between the two major legal traditions — Common Law and Civil Law?

Professor Pistor's answer was highly illuminating. She noted that the common law system grants private parties and their lawyers enormous flexibility to "create new rights using legal materials" — lawyers can continually innovate within the framework of case law, devising unprecedented legal structures. In civil law systems, judges function more like members of a bureaucratic apparatus, tending to strictly apply codified provisions, leaving relatively limited space for private innovation of legal instruments.

However, she also pointed out that artificial intelligence and digital technology are blurring this distinction. The algorithmic decision-making systems created by digital platforms are acquiring something akin to "quasi-sovereign power" — they determine who can obtain a loan, who gets hired, and whose content is visible. Regardless of which legal tradition we operate under, we need to rethink how to use legal tools to constrain these new forms of private power.^[5]

VI. COVID-19 and the Crisis Moment of Legal Coding

In the final question of our dialogue, I asked Professor Pistor to comment on the impact of the COVID-19 pandemic on the legal coding of capital. Her response was profoundly insightful: "The pandemic did not create new inequalities — it exposed and reinforced the structures of inequality that law had already created."

She illustrated this point with specific policy choices: amid the pandemic's impact, central banks decided to bail out certain institutions but not others; governments decided whether to suspend tenant evictions and whether to delay debt enforcement. These decisions were essentially choices made within legal frameworks — whose legal rights are protected first, and whose rights are temporarily frozen, determines who bears the cost of the crisis.

Professor Pistor emphasized that crises are often catalysts for legal change. After every major economic crisis, the rules of legal coding undergo adjustment — the question is whether the adjustment reinforces existing power structures or evolves toward greater fairness. This depends on society's understanding of the nature of law: if we continue to view law as a "neutral technical tool," it will continue to serve the few who possess coding capabilities; only by recognizing that law is the core mechanism for creating both wealth and inequality can we drive genuine institutional reform.

VII. Reflections: Implications of Legal Thinking for Policy Design and Education

This dialogue with Professor Pistor opened a completely new window of thought for me. As someone trained in legal studies at the doctoral level who later moved into business education and technology policy research, I am deeply struck by the power of this analytical framework.

In fintech regulation, Professor Pistor's legal coding theory provides a path of thinking that transcends the binary opposition of "regulation vs. innovation." The key is not whether to regulate, but understanding how emerging technology companies use legal tools to redefine rights and obligations — only by grasping this can regulators design institutional frameworks that both promote innovation and safeguard fairness.

In global governance, the concept of the "empire of law" profoundly reveals the invisible structure of the international economic order. When we discuss "de-globalization" or "decoupling," what is really happening is the fracturing of mutual recognition and mutual trust among national legal systems — and this is more destructive than trade barriers.

In educational philosophy, this dialogue reinforces my long-held conviction: business education cannot be divorced from legal literacy. The creation and distribution of wealth is not merely the result of market forces but also the product of legal institutional design. In my teaching at the business school, I have always emphasized interdisciplinary thinking — and Professor Pistor's work represents the most brilliant intersection of law and economics.

As Professor Pistor's core argument throughout our dialogue makes clear: the code of capital is written in law. Understanding this code is not only the key to understanding inequality but also the prerequisite for participating in institutional reform. In an era when legal coding capabilities are increasingly concentrated in the hands of a few, democratizing this knowledge — enabling more people to understand how law creates wealth and inequality — is perhaps the most important mission of public education.
