Unlocking Digital Competition — the Furman Review

Summary

Unlocking Digital Competition (March 2019) is the report of the UK's Digital Competition Expert Panel, commissioned by HM Treasury and chaired by Jason Furman (former chair of the U.S. Council of Economic Advisers), with panel members Diane Coyle, Amelia Fletcher, Philip Marsden and Derek McAuley — an interdisciplinary mix of economics, law and computer science.[1] Widely known as the Furman Review, it became one of the intellectual foundations of the UK's Digital Markets, Competition and Consumers Act and a template cited across the EU's Digital Markets Act debate.

For a Geoist reference the report is valuable on the diagnosis side of the digital-rent question — the "is it a rent?" evidence the wiki treats as genuinely contested. The Furman Review argues that many digital markets "tip" to a single dominant firm whose position is made durable by network effects and returns to scale on data, and that this durability is the core competition problem. But its prescription sits on the dissolve-the-advantage side of the Geoist menu, not the capture-the-rent side: it recommends interoperability, data mobility and tougher merger and antitrust enforcement — deliberately not a rent tax or a data dividend. That combination makes it a good source for the diagnosis and an instructive contrast on remedies.

The Diagnosis: Tipping, Network Effects and Data Returns

The Panel's guiding propositions frame concentration as often efficient but potentially durable and self-reinforcing. Its second proposition is the central one for the rent question:

"In many cases, digital markets are subject to 'tipping' in which a winner will take most of the market."[1]

Tipping, the report argues, is driven by a combination of economies of scale and scope, network externalities on either side of a platform, product/hardware integration, consumer default and prominence effects, difficulty raising capital, and brand. Crucially, the Panel judges that "competition for the market cannot be counted on, by itself" to correct this, because the forces entrenching incumbents have strengthened over time:

"network effects and returns to scale of data appear to be even more entrenched and the market seems to have stabilised quickly compared to the much larger degree of churn in the early days of the World Wide Web."[1]

It adds a forward-looking warning that if the next technological wave centres on artificial intelligence and machine learning, the firms best placed to exploit it "may well be the existing large companies because of the importance of data" — an early statement of the data-entrenchment concern the wiki tracks elsewhere (see Korinek & Ng on digital superstars). The report documents the concentration it is worried about: in December 2018 Google held over 90% of UK search and had done so "for more than a decade," and Google and Facebook dominated a £11.55 billion (2017) UK digital-advertising market.[1]

This is a careful, mainstream, non-Georgist source concluding that dominant platform positions are durable and hard to compete away — the empirical precondition for calling platform returns a rent rather than a transient lead.

The Prescription: Dissolve, Don't Capture

Where the Furman Review parts company with a rent-capture program is on remedies. Its central recommendation is a digital markets unit with three functions:

• a code of competitive conduct binding only on firms designated with "strategic market status" — enduring market power over a strategic bottleneck — to avoid burdening smaller entrants;
• personal data mobility and open standards, so users can move their data and networks between services (the report cites Open Banking and phone-number portability as precedents where regulation, not voluntary effort, achieved interoperability);
• data openness, giving entrants access to non-personal or anonymised data that forms a key barrier to entry, while protecting privacy.

It pairs these with a more forward-looking merger policy (arguing the correct economic analysis "would result in more merger enforcement," given that no acquisition by a major platform had ever been blocked) and faster antitrust tools. Chapter 3 singles out the digital-advertising value chain for a dedicated market study into whether competition is working (Strategic Recommendation E).[1] Every one of these instruments is designed to erode the durable advantage — to make the location contestable — rather than to tax the rent it throws off.

Relation to the Georgist Case — Diagnosis Strong, Remedy Off the Georgist Path

The Furman Review sits on the contested frontier of the rent gradient, and it sharpens the wiki's honesty rule in two directions.

• It strengthens the "durable position" half of the rent reading. The report's core empirical claim — that network effects and data returns tip digital markets and keep them tipped — is precisely the durability that distinguishes a rent (income from an exclusive, hard-to-reproduce position) from a transient competitive lead. That an official UK panel with no Georgist framing reaches this conclusion is meaningful outside corroboration for the platform and data rents diagnosis.
• But it explicitly reads much concentration as efficiency. The Panel is emphatic that "there is nothing inherently wrong about being a large company or a monopoly" and that dominance often "reflect[s] efficiencies and benefits for consumers." That is the quasi-rent side of the dispute the wiki refuses to flatten — the same tension carried on data-rents, the Crouzet & Eberly intangibles counter, and the steelman at taxing quasi-rents kills innovation. The report's whole method — consumer-welfare competition analysis — treats the returns as something to make contestable, not something to confiscate.
• It is the "dissolve the rent" pole of the Geoist menu, in its purest form. The wiki's treatment of digital rents lists two families of response: capture (rent-targeting taxes, data dividends — e.g. Romer's ad tax, the data-as-labor program in Radical Markets) and dissolve (interoperability, data portability, antitrust). The Furman Review is the flagship dissolve document: if data mobility and open standards let users leave with their networks, the location loses its lock-in and the rent competes away without ever being taxed. On the gradient's logic this is attractive precisely because, unlike land, a platform advantage can in principle be dissolved — land cannot be un-scarce, so it must be taxed; a data moat can be opened, so competition may substitute for capture.

The honest Geoist takeaway: the Furman Review is a strong source that platform positions are durable, and a strong reminder that on the digital frontier the right instrument may be competition policy rather than a rent tax — a choice the clean land case never has to make.

Nuances and Limits

• Not a rent-capture document, and not framed in rent terms. The report never uses the language of economic rent or rent capture; it is a competition-policy report grounded in consumer welfare. Reading it as evidence in the rent debate is the wiki's synthesis, and should be presented as such, not attributed to the Panel.
• It endorses the efficiency reading it also worries about. The Panel repeatedly credits concentration with real benefits and zero-price services, and warns regulators against their own informational disadvantages and capture. It is genuinely balanced, not a prosecution brief — cite it as a careful diagnosis, not as a finding that platform profits are unearned.
• A policy report, not peer-reviewed research. It is an expert-panel advisory document (weighty and widely cited, but institutional rather than academic), and its market-share figures rely on Statcounter and industry estimates the report itself flags as indicative rather than from a full market-definition exercise.
• Successor evidence exists. The UK Competition and Markets Authority's later digital advertising market study (2020) and the U.S. House Judiciary and Stigler Center reports develop the same diagnosis in more detail; this page covers the Furman Review specifically.
