Congressman Buck’s “Third Way” report offers a compromise between the House Judiciary Committee’s majority report, which proposes sweeping new regulation of tech companies, and the status quo, which Buck argues is unfair and insufficient. But though Buck rejects many of the majority’s reports proposals, what he proposes instead would lead to virtually the same outcome via a slightly longer process. 

The most significant majority proposals that Buck rejects are the structural separation to prevent a company that runs a platform from operating on that platform “in competition with the firms dependent on its infrastructure”, and line-of-business restrictions that would confine tech companies to a small number of markets, to prevent them from preferencing their other products to the detriment of competitors.

Buck rules these out, saying that they are “regulatory in nature [and] invite unforeseen consequences and divert attention away from public interest antitrust enforcement by our antitrust agencies.” He goes on to say that “this proposal is a thinly veiled call to break up Big Tech firms.”

Instead, Buck endorses, either fully or provisionally, measures including revitalising the essential facilities doctrine, imposing data interoperability mandates on platforms, and changing antitrust law to prevent “monopoly leveraging and predatory pricing”. 

Put together, though, these would amount to the same thing that the Democratic majority report proposes: a world where platforms are basically just conduits, regulated to be neutral and open, and where the companies that run them require a regulator’s go-ahead for important decisions — a process that would be just as influenced lobbying and political considerations, and insulated from market price signals, as any other regulator’s decisions are.

Revitalizing the essential facilities doctrine

Buck describes proposals to “revitalize the essential facilities doctrine” as “common ground” that warrant further consideration. This would mean that platforms deemed to be “essential facilities” would be required to offer access to their platform to third parties at a “reasonable” price, except in exceptional circumstances. The presumption would be that these platforms were anticompetitively foreclosing third party developers and merchants by either denying them access to their platforms or by charging them “too high” prices. 

This would require the kind of regulatory oversight that Buck says he wants to avoid. He says that “conservatives should be wary of handing additional regulatory authority to agencies in an attempt to micromanage platforms’ access rules.” But there’s no way to avoid this when the “facility” — and hence its pricing and access rules — changes as frequently as any digital platform does. In practice, digital platforms would have to justify their pricing rules and decisions about exclusion of third parties to courts or a regulator as often as they make those decisions.

If Apple’s App Store were deemed an essential facility such that it is presumed to be foreclosing third party developers any time it rejected their submissions, it would have to submit to regulatory scrutiny of the “reasonableness” of its commercial decisions on, literally, a daily basis.

That would likely require price controls to prevent platforms from using pricing to de facto exclude third parties they did not want to deal with. Adjudication of “fair” pricing by courts is unlikely to be a sustainable solution. Justice Breyer, in Town of Concord v. Boston Edison Co., considered this to be outside the courts’ purview:

[H]ow is a judge or jury to determine a ‘fair price?’ Is it the price charged by other suppliers of the primary product? None exist. Is it the price that competition ‘would have set’ were the primary level not monopolized? How can the court determine this price without examining costs and demands, indeed without acting like a rate-setting regulatory agency, the rate-setting proceedings of which often last for several years? Further, how is the court to decide the proper size of the price ‘gap?’ Must it be large enough for all independent competing firms to make a ‘living profit,’ no matter how inefficient they may be? . . . And how should the court respond when costs or demands change over time, as they inevitably will?

In practice, infrastructure treated as an essential facility is usually subject to pricing control by a regulator. This has its own difficulties. The UK’s energy and water infrastructure is an example. In determining optimal access pricing, regulators must determine the price that weighs competing needs to maximise short-term output, incentivise investment by the infrastructure owner, incentivise innovation and entry by competitors (e.g., local energy grids) and, of course, avoid “excessive” pricing. 

This is a near-impossible task, and the process is often drawn out and subject to challenges even in markets where the infrastructure is relatively simple. It is even less likely that these considerations would be objectively tractable in digital markets.

Treating a service as an essential facility is based on the premise that, absent mandated access, it is impossible to compete with it. But mandating access does not, on its own, prevent it from extracting monopoly rents from consumers; it just means that other companies selling inputs can have their share of the rents. 

So you may end up with two different sets of price controls: on the consumer side, to determine how much monopoly rent can be extracted from consumers, and on the access side, to determine how the monopoly rents are divided.

The UK’s energy market has both, for example. In the case of something like an electricity network, where it may simply not be physically or economically feasible to construct a second, competing network, this might be the least-bad course of action. In such circumstances, consumer-side price regulation might make sense. 

But if a service could, in fact, be competed with by others, treating it as an essential facility may be affirmatively harmful to competition and consumers if it diverts investment and time away from that potential competitor by allowing other companies to acquire some of the incumbent’s rents themselves.

The HJC report assumes that Apple is a monopolist, because, among people who own iPhones, the App Store is the only way to install third-party software. Treating the App Store as an essential facility may mean a ban on Apple charging “excessive prices” to companies like Spotify or Epic that would like to use it, or on Apple blocking them for offering users alternative in-app ways of buying their services.

If it were impossible for users to switch from iPhones, or for app developers to earn revenue through other mechanisms, this logic might be sound. But it would still not change the fact that the App Store platform was able to charge users monopoly prices; it would just mean that Epic and Spotify could capture some of those monopoly rents for themselves. Nice for them, but not for consumers. And since both companies have already grown to be pretty big and profitable with the constraints they object to in place, it seems difficult to argue that they cannot compete with these in place and sounds more like they’d just like a bigger share of the pie.

And, in fact, it is possible to switch away from the iPhone to Android. I have personally switched back and forth several times over the past few years, for example. And so have many others — despite what some claim, it’s really not that hard, especially now that most important data is stored on cloud-based services, and both companies offer an app to switch from the other. Apple also does not act like a monopolist — its Bionic chips are vastly better than any competitor’s and it continues to invest in and develop them.

So in practice, users switching from iPhone to Android if Epic’s games and Spotify’s music are not available constrains Apple, to some extent. If Apple did drive those services permanently off their platform, it would make Android relatively more attractive, and some users would move away — Apple would bear some of the costs of its ecosystem becoming worse. 

Assuming away this kind of competition, as Buck and the majority report do, is implausible. Not only that, but Buck and the majority believe that competition in this market is impossible — no policy or antitrust action could change things, and all that’s left is to regulate the market like it’s an electricity grid. 

And it means that platforms could often face situations where they could not expect to make themselves profitable after building their markets, since they could not control the supply side in order to earn revenues. That would make it harder to build platforms, and weaken competition, especially competition faced by incumbents.

Mandating interoperability

Interoperability mandates, which Buck supports, require platforms to make their products open and interoperable with third party software. If Twitter were required to be interoperable, for example, it would have to provide a mechanism (probably a set of open APIs) by which third party software could tweet and read its feeds, upload photos, send and receive DMs, and so on. 

Obviously, what interoperability actually involves differs from service to service, and involves decisions about design that are specific to each service. These variations are relevant because they mean interoperability requires discretionary regulation, including about product design, and can’t just be covered by a simple piece of legislation or a court order. 

To give an example: interoperability means a heightened security risk, perhaps from people unwittingly authorising a bad actor to access their private messages. How much is it appropriate to warn users about this, and how tight should your security controls be? It is probably excessive to require that users provide a sworn affidavit with witnesses, and even some written warnings about the risks may be so over the top as to scare off virtually any interested user. But some level of warning and user authentication is appropriate. So how much? 

Similarly, a company that has been required to offer its customers’ data through an API, but doesn’t really want to, can make life miserable for third party services that want to use it. Changing the API without warning, or letting its service drop or slow down, can break other services, and few users will be likely to want to use a third-party service that is unreliable. But some outages are inevitable, and some changes to the API and service are desirable. How do you decide how much?

These are not abstract examples. Open Banking in the UK, which requires interoperability of personal and small business current accounts, is the most developed example of interoperability in the world. It has been cited by former Chair of the Council of Economic Advisors, Jason Furman, among others, as a model for interoperability in tech. It has faced all of these questions: one bank, for instance, required that customers pass through twelve warning screens to approve a third party app to access their banking details.

To address problems like this, Open Banking has needed an “implementation entity” to design many of its most important elements. This is a de facto regulator, and it has taken years of difficult design decisions to arrive at Open Banking’s current form. 

Having helped write the UK’s industry review into Open Banking, I am cautiously optimistic about what it might be able to do for banking in Britain, not least because that market is already heavily regulated and lacking in competition. But it has been a huge undertaking, and has related to a relatively narrow set of data (its core is just two different things — the ability to read an account’s balance and transaction history, and the ability to initiate payments) in a sector that is not known for rapidly changing technology. Here, the costs of regulation may be outweighed by the benefits.

I am deeply sceptical that the same would be the case in most digital markets, where products do change rapidly, where new entrants frequently attempt to enter the market (and often succeed), where the security trade-offs are even more difficult to adjudicate, and where the economics are less straightforward, given that many services are provided at least in part because of the access to customer data they provide. 

Even if I am wrong, it is unavoidable that interoperability in digital markets would require an equivalent body to make and implement decisions when trade-offs are involved. This, again, would require a regulator like the UK’s implementation entity, and one that was enormous, given the number and diversity of services that it would have to oversee. And it would likely have to make important and difficult design decisions to which there is no clear answer. 

Banning self-preferencing

Buck’s Third Way would also ban digital platforms from self-preferencing. This typically involves an incumbent that can provide a good more cheaply than its third-party competitors — whether it’s through use of data that those third parties do not have access to, reputational advantages that mean customers will be more likely to use their products, or through scale efficiencies that allow it to provide goods to a larger customer base for a cheaper price. 

Although many people criticise self-preferencing as being unfair on competitors, “self-preferencing” is an inherent part of almost every business. When a company employs its own in-house accountants, cleaners or lawyers, instead of contracting out for them, it is engaged in internal self-preferencing. Any firm that is vertically integrated to any extent, instead of contracting externally for every single ancillary service other than the one it sells in the market, is self-preferencing. Coase’s theory of the firm is all about why this kind of behaviour happens, instead of every worker contracting on the open market for everything they do. His answer is that transaction costs make it cheaper to bring certain business relationships in-house than to contract externally for them. Virtually everyone agrees that this is desirable to some extent.

Nor does it somehow become a problem when the self-preferencing takes place on the consumer product side. Any firm that offers any bundle of products — like a smartphone that can run only the manufacturer’s operating system — is engaged in self-preferencing, because users cannot construct their own bundle with that company’s hardware and another’s operating system. But the efficiency benefits often outweigh the lack of choice.

Self-preferencing in digital platforms occurs, for example, when Google includes relevant Shopping or Maps results at the top of its general Search results, or when Amazon gives its own store-brand products (like the AmazonBasics range) a prominent place in the results listing.

There are good reasons to think that both of these are good for competition and consumer welfare. Google making Shopping results easily visible makes it a stronger competitor to Amazon, and including Maps results when you search for a restaurant just makes it more convenient to get the information you’re looking for.

Amazon sells its own private label products partially because doing so is profitable (even when undercutting rivals), partially to fill holes in product lines (like clothing, where 11% of listings were Amazon private label as of November 2018), and partially because it increases users’ likelihood to use Amazon if they expect to find a reliable product from a brand they trust. According to Amazon, they account for less than 1% of its annual retail sales, in contrast to the 19% of revenues ($54 billion) Amazon makes from third party seller services, which includes Marketplace commissions. Any analysis that ignores that Amazon has to balance those sources of revenue, and so has to tread carefully, is deficient. 

With “commodity” products (like, say, batteries and USB cables), where multiple sellers are offering very similar or identical versions of the same thing, private label competition works well for both Amazon and consumers. By Amazon’s own rules it can enter this market using aggregated data, but this doesn’t give it a significant advantage, because that data is easily obtainable from multiple sources, including Amazon itself, which makes detailed aggregated sales data freely available to third-party retailers

Amazon does profit from sales of these products, of course. And other merchants suffer by having to cut their prices to compete. That’s precisely what competition involves — competition is incompatible with a quiet life for businesses. But consumers benefit, and the biggest benefit to Amazon is that it assures its potential customers that when they visit they will be able to find a product that is cheap and reliable, so they keep coming back.

It is even hard to argue that in aggregate this practice is damaging to third-party sellers: many, like Anker, have built successful businesses on Amazon despite private-label competition precisely because the value of the platform increases for all parties as user trust and confidence in it does.

In these cases and in others, platforms act to solve market failures on the markets they host, as Andrei Hagiu has argued. To maximize profits, digital platforms need to strike a balance between being an attractive place for third-party merchants to sell their goods and being attractive to consumers by offering low prices. The latter will frequently clash with the former — and that’s the difficulty of managing a platform. 

To mistake this pro-competitive behaviour with an absence of competition is misguided. But that is a key conclusion of Buck’s Third Way: that the damage to competitors makes this behaviour harmful overall, and that it should be curtailed with “non-discrimination” rules. 

Treating below-cost selling as “predatory pricing”

Buck’s report equates below-cost selling with predatory pricing (“predatory pricing, also known as below-cost selling”). This is mistaken. Predatory pricing refers to a particular scenario where your price cut is temporary and designed to drive a competitor out of business, so that you can raise prices later and recoup your losses. 

It is easy to see that this does not describe the vast majority of below-cost selling. Buck’s formulation would describe all of the following as “predatory pricing”:

  • A restaurants that gives away ketchup for free;
  • An online retailer that offers free shipping and returns;
  • A grocery store that sells tins of beans for 3p a can. (This really happened when I was a child.)

The rationale for offering below-cost prices differs in each of these cases. Sometimes it’s a marketing ploy — Tesco sells those beans to get some free media, and to entice people into their stores, hoping they’ll decide to do the rest of their weekly shop there at the same time. Sometimes it’s about reducing frictions — the marginal cost of ketchup is so low that it’s simpler to just give it away. Sometimes it’s about reducing the fixed costs of transactions so more take place — allowing customers who buy your products to return them easily may mean more are willing to buy them overall, because there’s less risk for them if they don’t like what they buy. 

Obviously, none of these is “predatory”: none is done in the expectation that the below-cost selling will drive those businesses’ competitors out of business, allowing them to make monopoly profits later.

True predatory pricing is theoretically possible, but very difficult. As David Henderson describes, to successfully engage in predatory pricing means taking enormous and rising losses that grow for the “predatory” firm as customers switch to it from its competitor. And once the rival firm has exited the market, if the predatory firm raises prices above average cost (i.e., to recoup its losses), there is no guarantee that a new competitor will not enter the market selling at the previously competitive price. And the competing firm can either shut down temporarily or, in some cases, just buy up the “predatory” firm’s discounted goods to resell later. It is debatable whether the canonical predatory pricing case, Standard Oil, is itself even an example of that behaviour.

Offering a product below cost in a multi-sided market (like a digital platform) can be a way of building a customer base in order to incentivise entry on the other side of the market. When network effects exist, so additional users make the service more valuable to existing users, it can be worthwhile to subsidise the initial users until the service reaches a certain size. 

Uber subsidising drivers and riders in a new city is an example of this — riders want enough drivers on the road that they know they’ll be picked up fairly quickly if they order one, and drivers want enough riders that they know they’ll be able to earn a decent night’s fares if they use the app. This requires a certain volume of users on both sides — to get there, it can be in everyone’s interest for the platform to subsidise one or both sides of the market to reach that critical mass.

The slightly longer road to regulation

That is another reason for below-cost pricing: someone other than the user may be part-paying for a product, to build a market they hope to profit from later. Platforms must adjust pricing and their offerings to each side of their market to manage supply and demand. Epic, for example, is trying to build a desktop computer game store to rival the largest incumbent, Steam. To win over customers, it has been giving away games for free to users, who can own them on that store forever. 

That is clearly pro-competitive — Epic is hoping to get users over the habit of using Steam for all their games, in the hope that they will recoup the costs of doing so later in increased sales. And it is good for consumers to get free stuff. This kind of behaviour is very common. As well as Uber and Epic, smaller platforms do it too. 

Buck’s proposals would make this kind of behaviour much more difficult, and permitted only if a regulator or court allows it, instead of if the market can bear it. On both sides of the coin, Buck’s proposals would prevent platforms from the behaviour that allows them to grow in the first place — enticing suppliers and consumers and subsidising either side until critical mass has been reached that allows the platform to exist by itself, and the platform owner to recoup its investments. Fundamentally, both Buck and the majority take the existence of platforms as a given, ignoring the incentives to create new ones and compete with incumbents. 

In doing so, they give up on competition altogether. As described, Buck’s provisions would necessitate ongoing rule-making, including price controls, to work. It is unlikely that a court could do this, since the relevant costs would change too often for one-shot rule-making of the kind a court could do. To be effective at all, Buck’s proposals would require an extensive, active regulator, just as the majority report’s would. 

Buck nominally argues against this sort of outcome — “Conservatives should be wary of handing additional regulatory authority to agencies in an attempt to micromanage platforms’ access rules” — but it is probably unavoidable, given the changes he proposes. And because the rule changes he proposes would apply to the whole economy, not just tech, his proposals may, perversely, end up being even more extensive and interventionist than the majority’s.

Other than this, the differences in practice between Buck’s proposals and the Democrats’ proposals would be trivial. At best, Buck’s Third Way is just a longer route to the same destination.
