The Taxi Licence That Cost More Than a House
Cities capped the number of taxis and made the permits transferable, which turned a licence to operate into an appreciating asset people borrowed against. When the cap stopped binding, the asset went to nearly nothing.
Turning a Restriction Into an Asset
A city that limits the number of taxis has created scarcity. If the permits are non transferable, that scarcity produces higher fares and higher driver incomes and nothing else.
If the permits are transferable, something different happens. The right to operate can be bought and sold, and its price reflects the present value of the excess earnings the restriction produces. The regulatory limit has been converted into a private asset.
New York medallions were the most famous example, with prices rising over decades to exceed a million dollars for a single permit, which is a remarkable valuation for a piece of metal conferring permission to drive a car.
Why the Price Kept Rising
Several forces compounded. The number of medallions was essentially fixed for decades while the city population and economy grew, so demand for rides rose against fixed supply.
The permits were financeable, and specialist lenders including credit unions built businesses lending against them. That financing was self reinforcing: available credit raised what buyers could pay, higher prices raised the collateral value, and higher collateral value supported more lending.
The city itself participated, auctioning new medallions periodically and receiving substantial revenue, which gave it a direct fiscal interest in high prices.
| Participant | Interest in High Medallion Prices |
|---|---|
| Existing owner | Asset appreciation |
| Lender | Larger loans, better collateral |
| City government | Auction proceeds and transfer taxes |
| New driver buying in | Larger debt to service |
Every party with influence over the number of permits benefited from there being few of them. That alignment is the reason such systems persist long after the original justification has weakened, and it is why the eventual correction is so violent.
What the Asset Actually Was
It is worth stating plainly what a buyer was purchasing. The medallion produced no output. It generated income only because the city prohibited others from providing the same service.
The value was therefore entirely a claim on a regulatory decision to keep the restriction in place. Nothing physical backed it and no cash flow existed independent of the prohibition.
Assets of that kind exist in several markets, including agricultural production quotas and certain fishing rights, and they share the same property: the value is a capitalised regulation and it survives only as long as the regulation does.
The Collapse
Ride hailing platforms entered under a different regulatory classification and were not subject to the medallion cap. The effective supply of for hire vehicles multiplied, and the scarcity the medallion capitalised ceased to exist.
Prices fell by roughly ninety percent. Owners who had borrowed to buy at peak prices held debt far exceeding the collateral value and income insufficient to service it. Several lending institutions failed or were absorbed.
Subsequent investigations documented lending practices that had made the collapse far more damaging: loans with balloon payments, interest only structures, personal guarantees, and inadequate assessment of borrower ability to repay, extended to buyers with limited financial literacy and, frequently, limited English.
The city eventually established a relief programme restructuring medallion debt with a backstop, which was an acknowledgement that the harm was not simply a market outcome.
The General Lesson About Quota Assets
The episode illustrates a pattern that recurs wherever a transferable quota exists.
The restriction creates value. The value gets capitalised into a price. The price gets financed. Financing creates a constituency with a strong interest in the restriction never being relaxed. And the eventual relaxation, whether by policy change or by technological circumvention, destroys wealth that individuals borrowed to acquire in good faith.
Policymakers face a genuine dilemma at that point. Maintaining the restriction protects people who paid for it and preserves an inefficiency. Removing it improves the market and ruins people who bought an asset the government created and sold.
Where the Structure Still Operates
Transferable quotas remain widespread and, in several applications, work well. Individual transferable quotas in fisheries have been credited with reducing overfishing by giving participants a stake in the long term health of the stock. Milk production quotas in some countries perform a supply management function. Emissions allowances operate on the same principle.
The distinguishing feature of the successful ones is that the restriction serves a purpose that will not disappear, since a fishery genuinely requires limits. The medallion cap was justified on congestion and quality grounds that became far weaker once dispatch technology and driver rating systems existed.
The Bottom Line
A transferable operating licence converts a regulatory restriction into a financial asset, and the asset is worth exactly as much as the restriction is durable. Medallions demonstrated the full cycle: decades of appreciation, a lending industry built on it, a constituency invested in permanence, and a collapse when the scarcity was circumvented rather than repealed. The general caution is that any asset whose entire value is a capitalised prohibition carries a risk that no financial analysis of its cash flows will reveal.
