While reading this recent article on The Economist (https://www.economist.com/finance-and-economics/2026/08/31/the-extraordinary-rise-of-miamis-economy), Miami’s fiscal setting caught my attention.
On a Friday night in Miami, a $50 million house changes hands. Somewhere nearby, another tower rises above Brickell. A hedge fund announces another expansion. A family office arrives from New York. A technology company opens an office. A private-equity firm moves south. The money arrives first. The cranes follow. Then come the headlines.
Miami is booming.
It is becoming Wall Street South. It is attracting the wealthy, the ambitious, the mobile and the globally connected. Its economy has expanded rapidly, its skyline has changed almost beyond recognition, and the city has become one of the clearest symbols of America’s post-pandemic geographic reshuffling.
The numbers are real, but they can tell two stories at once.
Between 2020 and 2024, the Miami metropolitan area’s GDP increased by roughly 23%, compared with about 13% for the United States as a whole. By 2024, the Miami–Fort Lauderdale–West Palm Beach metropolitan economy was worth roughly $575 billion.
That is extraordinary growth. It is also not, by itself, proof of what caused it. And this distinction matters. Because there are at least two very different ways for a place to become richer. The first is development. The second is capture.
Call them Mechanism A and Mechanism B.
Mechanism A — the big push: investment creates new productive capacity. Infrastructure arrives. Firms appear. Workers follow. Agglomeration effects develop. The productive frontier moves outward.
Mechanism B — capital capture: mobile capital, firms and high-income households relocate toward an attractive jurisdiction. Economic activity moves geographically. The destination becomes richer, at least on paper, while some of the activity it gains is activity another place has lost.
The distinction is not semantic. It is the difference between creating a bigger pie and moving pieces of the pie around the table.
The economics literature has spent decades wrestling with exactly this problem. Kline and Moretti’s work on the Tennessee Valley Authority provides perhaps the clearest example of a genuine big push: coordinated public investment generated manufacturing agglomeration effects that persisted after the original subsidies disappeared. But the same literature warns that local gains from place-based policies can be offset by losses elsewhere. Miami is interesting because the current story looks much more like B dressed as A. And once that possibility is considered, the city’s extraordinary rise begins to look rather different.
The Motif Stated
Miami has done this before.
The city that now markets itself as a global financial centre once became famous for a rather different kind of capital.
In the early 1980s, Miami was described as the Wall Street of an underground economy. Banks along Brickell Boulevard received enormous quantities of so-called “flight capital” from Latin America, while the cocaine trade turned South Florida into a major node in an international illicit economy. Contemporary reporting described the extraordinary volume of cash entering the city’s financial system.
At almost exactly the same moment, another enormous movement was reshaping the city.
In 1980, more than 100,000 Cubans arrived in the United States through the Mariel Boatlift. Miami absorbed a labour-force shock equivalent to roughly 7% of its labour force. David Card’s famous study subsequently found remarkably little effect on the wages or unemployment of less-skilled workers, partly because Miami had already developed an unusually flexible labour market capable of absorbing large immigrant inflows.
The details matter because they reveal something fundamental about Miami. The city has repeatedly functioned as an absorber of mobility.
People move through it. Capital moves through it. Money moves through it. Industries move through it. The city itself becomes the infrastructure through which these movements are converted into buildings, employment, consumption and eventually urban identity. The 1980s version was chaotic, violent and frequently illegal. The twenty-first-century version is legal, institutional and considerably better dressed. The mechanism, however, has an uncomfortable resemblance. Something valuable arrives from elsewhere. Miami absorbs it, the city grows.
And eventually the question becomes:
Who actually captures the gains?
The Motif Returns
The modern migration is easier to photograph.
The cocaine cowboys have been replaced by hedge-fund managers.
Brickell is now populated by investment firms, law firms, technology companies, family offices and private-equity firms. Citadel itself announced Miami as its global headquarters in 2022 and is developing a new headquarters in Brickell.
JLL, whose business is deeply connected to commercial real estate, has highlighted the arrival or expansion of firms including Blackstone, Citadel, Spotify, Thoma Bravo and Marsh in South Florida. That is useful evidence of the relocation trend, although it should also be read with the obvious understanding that JLL has a commercial interest in Miami real estate.
Florida’s fiscal proposition is equally straightforward.
The state imposes no individual income tax. For somebody earning $10 million a year, geography is not merely geography, it is arithmetic. A wealthy household can change its address and materially change its tax burden without changing its profession, its portfolio, or even its social world very much. The incentive is therefore obvious. The question is what happens next.
Does the arrival of capital create a new productive ecosystem?
Or does it primarily bid up the value of an existing one?
The answer is probably somewhere in between.
Miami clearly has genuine economic expansion. Its metropolitan payroll increased by approximately 42,600 jobs between June 2024 and June 2025, a 1.5% increase. But the composition of those jobs is revealing. Education and health services added approximately 13,400 jobs; trade, transportation and utilities added around 10,300; professional and business services added 6,600. Financial activities added only about 700 jobs, or 0.3%. This does not mean finance is irrelevant.
It means that the financial-centre narrative is not the same thing as the employment narrative.
The skyscrapers are real. The financial firms are real. The capital is real. But the economy underneath them is much broader. And that raises a more difficult question than whether Miami is growing. It asks what kind of growth is occurring.
The Inconvenient Finding
Here the story begins to reverse.
The Miami metropolitan area did not simply gain residents during the boom. It also lost them.
Between July 2024 and July 2025, Miami recorded approximately 113,700 net domestic out-migrants, according to Census estimates cited in analyses of the 2025 population data (note: this is a Census-based metro domestic-migration figure, while the IRS figure is Miami-Dade County tax-return migration. They are different geographies and concepts. That distinction is careful and explicit). The important word is domestic: Miami was simultaneously capable of attracting international migrants while losing residents to other parts of the United States.
This produces a peculiar demographic arithmetic. People are leaving. Capital is arriving. And the city is becoming more valuable. These things are not necessarily contradictory. They may actually be connected. The housing market provides the bridge.
In April 2026, WalletHub ranked Miami 182nd out of 182 U.S. cities for rental affordability. Its methodology compared median annual gross rent with median household income, and Miami’s ratio was approximately 33.77%.
That figure is already uncomfortable. The deeper point however is not that Miami has expensive apartments. It is that the price of participating in the local economy is being determined by a market increasingly connected to people whose incomes are not generated by the local median wage structure.
This is what happens when a city’s asset market becomes internationally tradable while its labour market remains local. The penthouse does not care what the schoolteacher earns. The hedge fund manager does not price a condominium according to the salary of the restaurant worker downstairs. The property market clears according to whoever is willing and able to pay. And so the city can become richer while becoming less accessible to the people who make the city function.
This is not uniquely Miami’s problem.
Hsieh and Moretti’s work on housing constraints makes the broader point: when productive cities restrict the ability of workers to access them, labour becomes spatially misallocated and aggregate economic growth suffers. The irony is almost too neat. A city can attract productive people while simultaneously pricing productive people out.
The Counter-Subject
This is where the story becomes more interesting than a simple “Miami is expensive” narrative.
The IRS’s migration data allow us to look not merely at how many people move, but at the income attached to those movements.
For 2022–2023, Miami-Dade County recorded roughly 43,900 inbound tax returns and 65,300 outbound returns, producing a net loss of about 21,400 filing households.
Yet the county recorded approximately $484 million in net adjusted gross income inflow. In other words: fewer households, more income. That is the incidence story in miniature. A place does not need to gain people in order to gain income. It needs to gain the right people.
The result is a city in which demographic and fiscal indicators can point in opposite directions. The population churn says: people are leaving. The income flow says: income is arriving. The GDP says: the economy is growing. The rent data says: access is becoming harder. None of these statements contradicts the others.
Together, they tell us what the boom actually looks like. The city is becoming more valuable to capital faster than it is becoming affordable to labour. And that is the leitmotif.
The Price of the Dream
There is another number worth taking seriously.
The Bureau of Economic Analysis estimates the Miami metropolitan area’s 2024 Regional Price Parity at approximately 114.2: in broad terms, the area’s prices were around 14% above the national price level. New York’s metropolitan RPP was approximately 112.6.
The popular story used to be simple:
Leave New York.
Move to Florida.
Pay less.
Keep more.
But once enough people follow that logic, the destination changes.
The arbitrage disappears. The capital inflow itself bids up the scarce assets. The tax advantage remains. The cheapness does not. That is one of the oldest mechanisms in economics.
If everybody discovers the same bargain, the bargain stops being a bargain. Miami may therefore have become a victim of its own success.
The very characteristics that made it attractive – sunshine, international connectivity, taxation, lifestyle, relatively limited state taxation, global capital access – became inputs into an asset-price mechanism.
And assets are not infinitely expandable. The coastline is not. Prime land is not. The most desirable neighbourhoods are not. Neither is the ability of infrastructure to absorb additional demand. So the adjustment appears somewhere. Increasingly, it appears in the price paid by residents.
Variations in Other Keys
Miami is not unique. The same basic experiment has been attempted in different forms elsewhere.
Dublin built the International Financial Services Centre and used taxation, institutional design and international integration to turn a relatively small city into a major European financial and corporate hub. Dubai constructed the Dubai International Financial Centre as a specialised legal and financial enclave designed specifically to attract internationally mobile capital. Bilbao pursued something different: infrastructure, cultural investment and urban redevelopment, using the Guggenheim and a much broader regeneration strategy as part of a deliberate transformation from industrial decline toward a service-oriented urban economy. Warsaw’s rise has been driven by another combination again: EU integration, foreign direct investment, human capital and the concentration of business services in a rapidly expanding metropolitan economy. These cases should not be collapsed into one category. They are not interchangeable. And that is precisely the point.
There are successful examples of place-making, but place-making requires more than attracting wealthy people. It requires institutions. Infrastructure. Housing. Human capital. Productive firms. Local linkages. And, crucially, mechanisms through which the benefits of external capital become embedded in the local economy.
The big question is therefore not:
Can a city attract capital?
Almost any sufficiently attractive jurisdiction can do that.
The question is:
Can it convert mobile capital into immobile productive capacity?
That is a much harder task.
The Deferred Bill
There is one final bill that Miami cannot relocate away from.
The weather.
Florida’s property-insurance market has become one of the clearest expressions of this problem.
The Florida Office of Insurance Regulation’s January 2025 data showed average homeowners premiums of approximately $6,045 in Miami-Dade County, $6,614 in Palm Beach County, and $9,058 in Monroe County.
These are not merely numbers on an insurance statement. They are prices attached to physical risk. And unlike a tax differential, they cannot simply be eliminated by moving a headquarters from Chicago to Miami. The risk remains attached to the asset. Climate remains attached to the coastline. Storm exposure remains attached to the building.
This is where Miami’s story begins to rhyme with The Fiscal Sanitarium.
There, the problem was capital flowing into systems whose vulnerabilities were temporarily hidden by favourable conditions. Here, capital flows into a city whose physical vulnerability cannot ultimately be negotiated away.
The financial market can move. The hedge fund can move. The family office can move. The resident can move. The building cannot.
Florida has also had to impose stronger structural-inspection and reserve requirements on older condominium buildings following the Surfside disaster. Current law requires milestone inspections for qualifying condominium and cooperative buildings and structural-integrity reserve studies for covered properties.
That is economically significant. For years, the apparent affordability of some condominium ownership depended partly on the ability to defer maintenance. Now the bill is arriving. Reserve funds must be rebuilt. Buildings must be inspected. Repairs must be financed. Insurance must be purchased. The deferred costs are becoming current costs. Again, the leitmotif returns. The capital arrives first.
The bill arrives later.
The Financial Centre That Is Not Yet One
There is perhaps no better reality check than the Global Financial Centres Index.
Miami is unquestionably becoming more important financially, but “Wall Street South” remains a metaphor rather than an established equivalence.
In GFCI 39, published in March 2026, Miami ranked 32nd globally, down from 29th in the previous edition. It remained behind New York, San Francisco, Los Angeles, Boston, Chicago and Washington among major North American centres.
That does not make Miami a failure. Quite the opposite.
Thirty-second in the world is impressive. But it does puncture the more extravagant version of the narrative. Miami is not New York in the sunshine. It is Miami.
And perhaps that is a better description of what is happening.
It is becoming a major node in a network of globally mobile capital without necessarily becoming the singular financial centre that the most enthusiastic boosters imagine. The distinction matters because a financial centre is not simply a collection of rich people and expensive buildings.
It is an ecosystem. Legal institutions. Capital markets. Specialised labour. Universities. Financial infrastructure. Information networks. Corporate headquarters. Deep professional services. And decades of accumulated relationships. Buildings can be constructed quickly. Institutions take longer.
The Question Behind the Question
So, did Miami’s boom happen because of Citadel?
No. That would be far too easy.
Citadel is an example of the phenomenon, not its causal explanation. Nor did Miami’s growth happen simply because Florida has no personal income tax. Nor because wealthy New Yorkers moved south. Nor because remote work became possible. Nor because sunshine became fashionable during the pandemic. The more convincing explanation is an interaction between several forces:
tax differentials,
remote work,
migration,
international capital,
real-estate demand,
existing infrastructure,
entrepreneurial ecosystems,
and the city’s long-established position as a gateway between the United States, Latin America and the Caribbean.
The difficult question is therefore not whether these forces produced growth. They clearly did. The difficult question is who receives the marginal benefit when they do. That is the question that turns a story about economic growth into a story about incidence.
The Leitmotif
This is why Miami belongs alongside the other subjects I have written about.
Elements of Predation asked what happens when markets are fragmented and value is captured by those best positioned to navigate them. Miami asks something similar at the urban scale: who captures the surplus when an existing place becomes more valuable?
Incessant Youth examined the economic structures that delay independence and make adulthood increasingly expensive. Miami offers the metropolitan version of the same phenomenon. A city can become wealthier while ordinary access to that city becomes harder. The Fiscal Sanitarium examined what happens when capital enters a system because its apparent conditions are attractive, only for hidden vulnerabilities to emerge later.
Miami has its own deferred bill:
insurance,
climate,
infrastructure,
maintenance,
housing.
Three different essays.
Three different subjects.
The same underlying question.
Who gets the upside, and who receives the invoice?
That, perhaps, is what makes this a leitmotif rather than a case study.
Coda
Cities have always competed for capital. They should.
Capital builds.
Capital employs.
Capital innovates.
Capital can transform places that have spent decades stagnating.
The mistake is not attracting capital. The mistake is assuming that capital inflow and development are synonymous.
They are not.
A city can attract a billion dollars and create genuine productive capacity. It can also attract a billion dollars and mostly make the land underneath it more expensive. Usually, it does some of both. The job of economic policy is to determine which dominates. That requires looking beyond GDP.
Beyond cranes. Beyond billionaire migrations. Beyond glossy towers. Beyond the number of headquarters announced in a given year.
Look instead at wages.
Employment composition.
Housing supply.
Migration by income.
Insurance.
Infrastructure.
Productivity.
Local business formation.
And the distribution of the gains.
Because a successful city should not merely become more valuable.
It should become more capable. Its residents should not have to leave in order for the balance sheet to improve. Its productive workers should not become collateral damage of its asset boom. And its prosperity should not depend upon continuously finding somebody richer to arrive next. Otherwise, the city has not escaped the old economic problem.
It has merely dressed it differently. The capital arrived. The skyline rose. The numbers improved. And somewhere below the penthouses, somebody received the bill.
The leitmotif returns.
