The Taxi Licence That Cost More Than a House

Turning a Restriction Into an Asset

A city that limits the number of taxis has created a shortage. If permits are not transferable that shortage produces higher fares and increased income for drivers and nothing more

If the permissions are transferable something different happens. The right to operate can be bought and sold and its price reflects the present value of the excess income produced by the restriction. The regulatory limit has become a private asset

The New York medallions were the most famous example whose prices rose over the decades to exceed $1 million for a single permit a remarkable valuation for a piece of metal that confers permission to drive a car

Transferability is the whole hinge and it's worth noting that it seems like an administrative detail when enacted. Allowing a permit holder to sell to a qualified buyer seems like flexibility for the permit holder. What it actually does is create a market and a market creates a price and a price is something that people can borrow insure inherit and build businesses around

Why the Price Kept Rising

Several forces came together. The number of medallions was essentially fixed for decades as the city's population and economy grew so travel demand increased in the face of fixed supply

The permits were financeable and specialized lenders including credit unions created businesses that lent against them. That financing was self-reinforcing: Available credit increased what buyers could pay higher prices raised the value of the collateral and greater value of the collateral supported more loans

The city itself participated periodically auctioning off new medallions and receiving substantial revenue which gave it a direct fiscal interest in the high prices

The Arithmetic of a Capitalised Restriction

It's helpful to see how a stream of additional profits turns into a seven-figure price because the calculation reveals what the buyer was actually paying. The figures below are illustrative and round

Suppose that having a medal allows an operator to earn more each year than the same person could earn driving in an unrestricted market. Call that excess $50,000 a year. That premium exists only because other people are prohibited from competing

To convert a perpetual annual flow into a price divide it by the return a buyer requires. Ask for 5 percent and the flow will be worth 50,000 divided by 0.05 which is $1,000,000. There is a million-dollar permit and nothing exotic was needed to produce it

Now change just the required return and watch what happens. It demands 10 percent and the same 50,000 a year is worth 500,000. It demands 20 percent and it's worth 250,000. Profits never moved. The price fell three-quarters

That sensitivity is the point. A required return is when a buyer expresses how confident he is and the dominant risk here is not whether people will continue to take taxis. The question is whether the restriction will still be there

So a buyer paying a million dollars was not simply assessing the profit. They claimed that the limit would remain in place indefinitely because only near-absolute certainty justified a discount at a rate low enough to reach that figure. The permanence of a municipal rule was built into the price as an assumption and no one was obligated to write it down or defend it

Which also explains why the final drop was so severe. A price built on the assumption that a restriction is permanent has no floor once that assumption is questioned since every layer of the valuation is based on it

What the Asset Actually Was

It is worth clearly stating what the buyer was purchasing. The medallion did not produce any results. It generated income only because the city prohibited others from providing the same service

Therefore the value was entirely a claim on a regulatory decision to keep the restriction in place. There was nothing physical to support it and no cash flow existed independent of the ban

Such assets exist in various markets including agricultural production quotas and certain fishing rights and share the same ownership: the value is a capitalized regulation and survives only as long as the regulation survives

Why the Borrowing Was the Real Exposure

A price collapse is painful. A debt-financed price collapse is a different category of event and the distinction explains why this episode ruined people rather than simply disappointing them

Consider a homeowner who bought outright with their own money. The price drops about ninety percent and they have lost about ninety percent of what they invested.That is a serious result and it is limited. They still have the permit they can still drive and no one can ask them for more

Now consider a homeowner who borrowed most of the purchase price. His equity is a small portion of the total so it disappears after a modest drop long before ninety percent is reached. Everything that follows is negative equity that is debt against an asset that is worth less than the loan. When the loan had a personal guarantee the risk does not end with the granting of permission. It follows the borrower

There's a second flaw underneath and it's the one the lenders overlooked. Ask what services the loan offers. The driver's income. Ask what that income depends on. The shortage created by the cap. Now ask what the collateral backs up. The same shortage

Therefore the borrower's ability to pay and the value of the security depended on an identical variable. This is the opposite of what secured loans are supposed to achieve since the entire premise of accepting collateral is that it has value when the borrower cannot pay

If we extend that to an entire portfolio of loans the situation is even more stark. A lender with thousands of medallion loans did not have a diversified portfolio of small loans. This was a concentrated bet on a single municipal rule written thousands of times. Every loan in the book was correlated with all the other loans essentially 100 percent which is why the institutions did not suffer large losses when the limit was no longer binding. They failed

The Collapse

Public transportation platforms entered under a different regulatory classification and were not subject to the medallion limit. The effective supply of rental vehicles multiplied and the shortage that the medallion capitalized on ceased to exist

Prices fell by approximately ninety percent. Homeowners who had gone into debt to buy at top prices had debt that far exceeded the value of the collateral and insufficient income to pay it off. Several lending institutions went bankrupt or were taken over

Later investigations documented lending practices that had made the collapse far more damaging: balloon-payment loans interest-only structures personal guarantees and inadequate assessments of the borrower's ability to pay extended to buyers with limited financial literacy and often limited English

The city eventually established a relief program to restructure the medallion debt with a backstop which was a recognition that the damage was not simply a result of the market

Circumvented, Not Repealed

The collapse mechanism deserves to be isolated because it's the part that generalizes and the part that was really hard to see coming

No one repealed the limit. No city council voted to flood the streets with taxis. The medallion limit remained exactly the same as it had always been and in a formal sense was never weakened at all

What happened is that a category appeared that the standard did not describe. Vehicles sent through an app were classified differently so the limit continued to link precisely the vehicles it had always linked while a much larger fleet operated alongside it under a separate framework

The consequence for anyone who owns the asset is serious because it nullifies the defense they would naturally have built. An owner concerned about regulatory risk protects themselves politically. They organize they lobby they cultivate the council they attend hearings. That machinery is designed to prevent a rule from being changed and the medal owners had it and used it

None of this helps against a rule that is never changed and simply stops mattering. There is no voting to win because voting never happens. By the time the effect is visible in fare revenue the competing fleet is already in circulation under a classification that was decided elsewhere

Which suggests the question worth asking about any such asset. Not whether the ban is likely to be overturned since that is the risk everyone is already seeing. Instead ask whether the same underlying activity can be performed in a way that the ban does not describe. A restriction defined by a technology or a business format rather than by the activity itself is liable to be made irrelevant by a format that no one thought to include in the definition

The General Lesson About Quota Assets

The episode illustrates a pattern that repeats itself whenever there is a transferable quota

The constraint creates value. The value is capitalized into a price. The price is financed. The financing creates an electorate with a strong interest in the constraint never being relaxed. And the eventual relaxation whether through policy change or technological circumvention destroys the wealth that individuals borrowed to acquire in good faith

At that point authorities face a real dilemma. Maintaining the restriction protects the people who paid for it and preserves inefficiency. Removing it improves the market and ruins the people who bought an asset that the government created and sold

The dilemma is more acute than the ordinary case of an industry resisting reform and the reason is that the government was a counterparty and not a spectator. It created the shortage authorized the transfers ran the auctions and collected the profits. A driver who paid the city for a permit and then watched as the city allowed a competing fleet has a complaint that is not merely economic which is the substance behind the eventual aid program

Where the Structure Still Operates

Transferable quotas are still widespread and in several applications work well. Individual transferable quotas in fisheries are credited with reducing overfishing by giving participants a stake in the long-term health of the population. Milk production quotas in some countries serve a supply management function. Emission allowances work on the same principle

The distinguishing feature of the successful ones is that the restriction serves a purpose that will not go away as a fishery really requires limits. The medallion limit was justified on congestion and quality grounds that became much weakened once dispatch technology and driver rating systems existed

The useful test is whether the shortage being sold is physical or administrative. A fish population is biologically finite and no innovation makes the limit unnecessary so a quota written against it has something durable at heart. An emissions limit is anchored to a physical quantity in the same way

The limit on the number of vehicles authorized under a given municipal framework is administrative. The congestion it was intended to address is real and the number of medallions was never a direct measure of it which is why a fleet operating outside the framework could multiply road traffic without formally touching the limit. The rule had lost touch with what it was supposed to limit long before anyone noticed the price

The Bottom Line

A transferable operating license turns a regulatory restriction into a financial asset and the asset is worth exactly as much as the restriction lasts. The medallions demonstrated the full cycle: decades of appreciation a credit industry built on it an electorate invested in permanence and a collapse when shortages were averted rather than repealed. The general caveat is that any asset whose full value is a capitalized ban carries a risk that no financial analysis of its cash flows will reveal. The cash flows were real at all times. Whatended was the phrase from a rule book that produced them
