The Economic
Development Fiction

Thirty years of independent research, more than 130 studies, and one finding repeated every time — and why public officials keep accepting projections that economists know to be wrong

Every stadium subsidy negotiation produces the same document: an economic impact study projecting thousands of jobs, hundreds of millions in new spending, and transformative development for the surrounding community. The projections are almost always wrong. The independent academic literature has said so consistently since 1990. This post examines what the research actually shows, why the projections are structurally designed to overstate benefits — and why, despite three decades of evidence, the fiction persists.

In 1997, Roger Noll and Andrew Zimbalist edited a volume published by the Brookings Institution titled Sports, Jobs, and Taxes: The Economic Impact of Sports Teams and Stadiums. It contained fifteen chapters of independent economic analysis examining whether stadiums produce the economic benefits their advocates claim. The conclusion, stated plainly in the book's preface: sports teams and stadiums are not a source of local economic growth and employment.

That was 1997. The comprehensive review of the academic literature published in the Journal of Economic Surveys in 2023 — covering more than 130 studies spanning more than 30 years — reached the same conclusion. Though findings have become more nuanced at the sub-local level, the review states, they "continue to confirm the decades-old consensus of very limited economic impacts of professional sports teams and stadiums."

Thirty years. More than 130 studies. The same finding.

The stadium subsidies continue.

What the Independent Research Shows

THE ACADEMIC RECORD — KEY FINDINGS ACROSS 30 YEARS

Baade and Dye (1990) — The Founding Study Robert Baade, Lake Forest College Examined stadium construction and metropolitan economic development across multiple cities. Found no statistically significant positive correlation between sports facility construction and local economic development. Established the baseline finding that the subsequent literature has consistently confirmed for three decades.

Noll and Zimbalist (1997) — The Policy Benchmark Roger Noll, Stanford; Andrew Zimbalist, Smith College — Brookings Institution Press Fifteen-chapter volume examining case studies across Baltimore, Chicago, Cincinnati, Cleveland, Indianapolis, San Francisco, and the Twin Cities. Primary conclusion: sports teams and stadiums are not a source of local economic growth and employment. The net subsidy exceeds the financial benefit of a new stadium. Cities likely subsidize sports teams because of intense popular support, not economic merit.

Coates and Humphreys (1999) — The Negative Finding Dennis Coates, UMBC; Brad Humphreys, University of Alberta Analyzed all US metropolitan statistical areas hosting major-league teams from the late 1960s through the mid-1990s. Finding: the presence of new stadiums and sports teams was associated with a NEGATIVE correlation with per capita personal income. Not zero — negative. Authors postulate this reflects residents accepting lower incomes in return for the nonpecuniary benefit of hosting a franchise, and the opportunity cost of public investment with higher returns elsewhere.

Siegfried and Zimbalist (2000) — The Consensus Statement Journal of Economic Perspectives Comprehensive review finding that independent work on stadiums and arenas has "uniformly found no statistically significant positive correlation between sports facility construction and economic development." The word "uniformly" is the operative term — not most studies, not the majority: uniform.

Coates (2015) — The 15-Year Update Dennis Coates, Mercatus Center Extended the Coates-Humphreys (1999) dataset by 17 years, covering 1969-2011 across all US metropolitan areas including NHL. Finding: no effects on wages or income. The additional 17 years of data produced no change in the conclusion.

Bradbury, Coates, Humphreys (2023) — The Comprehensive Survey Journal of Economic Surveys — 130+ studies, 30-year literature review Most comprehensive review of the literature available. Covers more than 130 studies across three decades. Conclusion: "Though findings have become more nuanced, recent analyses continue to confirm the decades-old consensus of very limited economic impacts of professional sports teams and stadiums." The consensus has not moved. The evidence base has grown substantially. The finding is the same.

Why the Projections Are Wrong — The Structural Explanation

The gap between what economic impact studies project and what independent research finds is not random error. It is structural. The projections are produced by consultants hired by the teams or the cities seeking to justify deals already under negotiation. These consultants use methodological choices that are individually defensible but collectively produce systematic overstatement.

The substitution effect is ignored. Fans have limited entertainment budgets. Money spent at a stadium on a given Saturday is money not spent at a restaurant, a movie theater, or a bowling alley in the same metropolitan area. The new spending is mostly displaced spending — not new economic activity. Impact studies that count gross stadium spending as new regional income are counting the same dollars twice.

The multiplier is applied to gross spending. Economic multiplier analysis estimates how many times a dollar circulates through a local economy before leaving it. Impact studies routinely apply high multipliers to total stadium spending — including the displaced entertainment spending that was already circulating in the local economy before the stadium existed. Applying a multiplier to gross spending rather than net new spending produces projections that are structurally inflated.

Leakage is excluded. A significant portion of stadium-related spending leaves the local economy immediately. Nationally contracted vendors, broadcast rights holders, visiting team payrolls, and out-of-market spending all reduce the local economic footprint of a stadium. Impact studies typically minimize or ignore these leakages.

NFL games are counted at full impact eight times a year. An NFL team plays eight regular-season home games annually. A department store is open 365 days. Independent economists have noted that a single mid-sized retail establishment generates more consistent local economic activity than a professional football franchise. The concentrated nature of stadium activity — heavy usage for a small number of days, minimal economic presence in the off-season — makes stadium-adjacent economic development projections structurally unreliable.

"If stadiums are poor investments, why, in the era of limited government skepticism about the nature of public construction projects, are expensive stadiums still being subsidized?" — Roger Noll and Andrew Zimbalist, Sports, Jobs, and Taxes (1997) — Brookings Institution Press

Noll and Zimbalist asked this question in 1997. The answer they offered then — and the answer the subsequent literature has confirmed — is that cities likely subsidize stadiums not because the economics justify it, but because of concentrated political pressure from organized franchise advocates against diffuse, unorganized taxpayer opposition. The economics are the justification. The politics are the cause.

The Advocacy Report vs. the Independent Study

There is a documented and consistent gap between economic impact figures produced by advocacy reports — commissioned by teams, leagues, or host-city boosters — and figures produced by independent academic research using the same underlying data.

The NFL routinely claims economic impacts from Super Bowls in the range of $400 million per event. Independent economists using post-event data have found actual measurable impacts substantially below these projections in virtually every case studied. Baade and Matheson's examination of the 1984 Los Angeles Olympics and the 1996 Atlanta Olympics found that even the most favorable independent estimate of Atlanta's economic impact was approximately one-third of what the host committee claimed.

The pattern is not specific to the NFL or to any particular city. The 2023 Bradbury-Coates-Humphreys survey notes that press release statements from stadium boosters are routinely quoted in news coverage without external validation of their credibility — and that economic impact estimates from advocacy reports may be repeated in public discourse without the methodological context that would allow readers to evaluate them.

The MLB Lobbying Memo — Primary Source Confirmation

The clearest primary source documentation of the architecture's self-awareness about the economic development argument is a document that appeared not in a court case or a legislative hearing, but in an internal MLB communication obtained and published by academic researchers.

PRIMARY SOURCE — MLB INTERNAL MEMO, DECEMBER 2017 In December 2017, during Congressional negotiations over the Tax Cuts and Jobs Act, the House of Representatives included a provision that would have prohibited cities from using tax-exempt bonds to finance new professional sports stadiums. Major League Baseball sent a memo to team owners describing the league's lobbying response. The memo stated, in part, that MLB had engaged in a "substantial lobbying effort" to remove the provision. It described "numerous calls by our Owners to House and Senate Leadership, key members of the Senate Finance and House Ways and Means Committees, and others." The House provision was removed from the final bill. The tax-exempt stadium bond mechanism survived. The memo is available in the academic literature through Bradbury, Coates, and Zimbalist's published research on stadium economics.

The memo is significant for what it confirms structurally. The leagues are not passive beneficiaries of the tax-exempt bond mechanism. They actively lobby to preserve it when Congress threatens to remove it — deploying franchise owners directly to committee members to protect a subsidy mechanism whose economic justification their own advocacy materials claim is self-evident. If the economic development benefits were as large as the projections claim, the lobbying would be unnecessary. The public would demand the subsidies on its own.

The Franchise Departure Experiment

The economic impact literature contains a natural experiment that is rarely discussed in public stadium negotiations: what happens to a city's economy when a franchise leaves?

If professional sports teams generate the economic activity their advocates claim, cities that lose franchises should experience measurable economic decline. Independent research has found no such effect. Coates and Humphreys's analysis of franchise departures found they were not associated with negative economic outcomes in host cities. The economic activity attributed to the franchise in the projections does not appear in the data when the franchise is gone.

Oakland lost the Raiders in 2020. The city's economic trajectory — challenged by housing costs, employment trends, and the departure of multiple major corporate anchors — was not measurably affected by the Raiders' departure in the direction the economic development argument would predict. The stadium was not an economic driver. Its absence was not an economic loss, in the quantitative terms the projections use.

FSA CHAIN · THE ECONOMIC DEVELOPMENT FICTION Source Political Necessity — Justification Required Public officials cannot openly approve large transfers of public wealth to private franchise owners without justification. Economic development is the justification the architecture requires. ↓ Conduit Commissioned Advocacy Studies Consultants hired by teams or cities produce projections using methodological choices (gross multipliers, ignored substitution, excluded leakage) that systematically overstate benefits. The studies are technically defensible individually. The aggregate bias is structural. ↓ Conversion Media Repetition Without Validation Press release figures enter news coverage as established facts. Independent academic findings — which contradict the projections — appear in peer-reviewed journals that public officials and local media rarely consult during stadium negotiations. ↓ Insulation Active Lobbying to Preserve the Mechanism When Congress threatens the tax-exempt bond subsidy, franchise owners make direct calls to committee members. The economic justification is deployed publicly. The lobbying operates privately. The mechanism survives because the people who benefit from it are organized and the people who pay for it are not.

CHAIN READING: The economic development argument is not a finding. It is a function. The architecture requires public justification for private subsidy. The advocacy study produces that justification on demand. The independent literature has contradicted it for thirty years. The subsidies continue because the political economy of concentrated benefits and diffuse costs makes the contradiction irrelevant to the outcome.

What FSA Cannot Determine

FSA WALL Whether specific economic impact studies were produced in bad faith, with deliberate methodological manipulation intended to mislead, is not established by available primary sources. The structural bias in the projections is documented. The intent of individual consultants or commissioners is beyond FSA's evidentiary reach. Whether stadiums produce nonpecuniary benefits — civic pride, quality of life, intangible community value — that justify subsidies independent of measurable economic impact is a legitimate values question that the economic literature acknowledges but cannot resolve. The Noll-Zimbalist literature explicitly notes that cities may rationally subsidize franchises for noneconomic reasons. FSA documents the economic argument's empirical failure. It does not adjudicate whether other reasons are sufficient. That is a political question, not an analytical one. The wall is here.
