Thiers set out to build this bridge. Bridges as Two-Sided Markets * * * Lacking both experience and theoretical knowledge, she didn’t realize that the bridge she was trying to build had the interesting properties of what economists call a two-sided market. These days, two-sided markets (sometimes called two-sided networks or two-sided platforms) are everywhere because many of today’s Internet start-ups are middlemen businesses of exactly this type: whether you’re talking about connecting homeowners with guests (Airbnb) or drivers with fares (Lyft and Uber) workers with small jobs (TaskRabbit) restaurants with diners wanting take-out meals (GrubHub, Eat24) or doctors with patients (ZocDoc), you’re describing a two-sided market. At the same time, and maybe not coincidentally, the study of two-sided markets has become a popular field among academics, with many opinions about what counts as a two-sided market.

Because buyers usually want to be where sellers are, and sellers usually want to be where buyers are, a two-sided network with an abundance of participants on one side tends to attract more comers on the other side. In the language of economics—and increasingly of tech investors—two-sided markets usually create “indirect network effects.”36 As one side grows, the network becomes more attractive to the other side, and as the other side grows, it attracts more users who want to connect with that side. This positive feedback loop promotes rapid growth once you reach critical mass. That’s why tech investors love network effects. But this same growth curve means two-sided markets are extremely hard to get off the ground, as Thiers found out firsthand: how do you get a sitter to sign up for a service that doesn’t have a single parent, and likewise, how do you get a parent to sign up for a service that has no sitters?

Rather, it’s that without both sides on board, there is no service at all. If you want to open a gift shop—a middleman business that by most definitions is not a two-sided market—you lease your retail space, you buy some inventory from a wholesaler, and you’re ready to roll: a wholesaler won’t refuse your prepaid order because you have no customers yet. But if, on the other hand, your whole value proposition is access to your network, then if you have no network, you’ve got nothing. So how can you possibly begin? The typical way out of this chicken-and-egg problem is for the middleman to subsidize one side, thus getting these initial users to sign up before there’s anything on the other side. Even after a two-sided market takes off, with plenty of users on both sides and therefore the potential to charge both sets of users, middlemen usually continue to offer the service for free to one side while making all their money from charging the other side for access, relying on these cross-subsidies for continued growth and profit.

The dense mathematics of his academic papers has served as a basis for regulatory policies on telecommunication networks. Tirole also applied himself to the question of how to regulate credit cards, which in turn led to a series of papers that aimed to understand two-sided markets more broadly: examining why they exist, what makes them different from the one-sided variety, and how competing platforms like Visa and Amex vie for customers on both sides of their respective markets, and providing some guiding principles for builders of two-sided markets and the authorities that regulate them. Much of Tirole’s work on platforms takes as its starting point that a two-sided market is one where participants on either side couldn’t simply find one another and strike a bargain in the absence of the platform standing between them.13 If they could, then they wouldn’t need the services of the platform.

It just wants to sell tickets to a lot of players and make sure the game is played on its turf.7 To do so, you have to ensure that the players you let onto the field actually enhance the platform’s value, so both sides stick around to play. (Think about the value proposition at eBay if conmen dominated its sellers’ ranks.) Looking at a two-sided market through this lens—as a space where people meet and not just where trade takes place—is a new angle to understanding exchange. The difference between one-sided and two-sided markets is subtle but meaningful. It changes the way that we might approach the market as a business or a consumer. And it affects how a regulator decides whether a platform can govern itself, or if there’s a need to step in to impose some rules on the businesses using the platform. The seemingly obscure rules of platforms have a great effect in your life.

The reason is, of course, because a bigger user base allows Google to extract ever-higher revenues from the other side of the market—the advertisers, who pay for search listings. In this case, stocking Google search results with more paid ads doesn’t do much to enhance the customer experience, so there’s a wide gap between what each side of the market pays to meet on Google. This state of affairs is entirely common in the realm of two-sided markets: many credit card companies don’t charge cardholders or even give them discounts, while merchants pay through the nose; shopping malls, a two-sided market from an earlier era, charge their tenants rent, while offering free parking and other inducements to attract shoppers. Sometimes the way that platforms charge can look perverse, until you understand the logic. Shopping malls charge their larger stores less money than smaller businesses because without those anchors to draw shoppers, the mall couldn’t exist.

This makes the design of monetization models more complex, since the platform must ensure that the value it gives away to one side can be used to capture value on the other side. Significant scholarly work has been done in this area. Two of this book’s authors (Geoff Parker and Marshall Van Alstyne) were among the first scholars to lay out the theory of two-sided market pricing.2 And the theory was mentioned as part of the 2014 Nobel Prize awarded to one of the other originators of two-sided market economics, Jean Tirole.3 Achieving the right balance among the complex factors involved in two-sided market pricing isn’t easy. Netscape, one of the pioneers of the Internet era, gave away browsers for free in hopes of selling web servers. Unfortunately, there was no proprietary connection between browsers and servers that Netscape could reliably control. Anyone could just as easily use Microsoft’s web server or the free Apache web server, which meant that Netscape was never able to monetize the other side of its free browser business.

Were the differences a matter of random luck, or were deeper design principles at work? What are the rules of the new economics of networks? Geoff and Marshall set about trying to answer these questions. It turned out to be a harder challenge than they expected. They ended up having to develop a new economic theory of two-sided networks. Their Harvard Business Review article “Strategies for Two-Sided Markets,” coauthored with Harvard professor Thomas R. Eisenmann, laid out what became one of the most widely taught theories of Internet business, one that is still taught in MBA programs around the world. Along with the work of other scholars, Geoff’s and Marshall’s insights helped to reshape mainstream thinking about business regulation. Later, at the MIT Initiative on the Digital Economy, they furthered their work with such firms as AT&T, Dun & Bradstreet, Cisco, IBM, Intel, Jawbone, Microsoft, Salesforce, SAP, Thomson Reuters, and many others.

See Jean-Charles Rochet and Jean Tirole, “Platform Competition in Two-Sided Markets,” Journal of the European Economic Association 1, no. 4 (2003). As is increasingly common in academic economics, their paper was widely circulated several years before it appeared in print. The term “two-sided market” has fallen out of favor, as it has become clear that two- or multisidedness is an attribute of individual businesses, not necessarily of all businesses in a market. A nontechnical discussion of this paper and other early economic papers on multisided platforms is given by Richard Schmalensee, “An Instant Classic: Rochet & Tirole, Platform Competition in Two-Sided Markets,” Competition Policy International 10, no. 2 (2014). 19. In suburban America, they even give people free parking and, often, entertainment.

Then they had the insight that these businesses, and many others that look very different on the surface, have the same underlying business model. They all facilitate direct interactions between different types of customers. And they must use nontraditional, counterintuitive strategies to make money and survive. After working out a pioneering economic model, they wrote a paper, “Platform Competition in Two-Sided Markets,” which began circulating among economists in 2000.18 Economists now call these businesses multisided platforms because some of them actually facilitate interactions between more than two types of customers, as we will soon see. Jean Tirole received the Nobel Memorial Prize in Economic Sciences in 2014 for a number of important accomplishments, including his pioneering contributions to the new economics of multisided platforms.

Most consumers of ad-supported media, for example, pay little if anything and are provided content of significant value. Transaction cost: The economists’ term for frictions; see “Friction.” Turbocharged matchmaker: A matchmaker, or multisided platform, that benefits from a significant combination of powerful computer chips, the Internet, the web, broadband communications, programming languages and operating systems, and the Cloud. Airbnb, for example, benefits from all of these technologies. Two-sided market: The original name used to refer to industries that had “two-sided platforms.” Two-sidedness is a characteristic of businesses, not always of industries, however. Two-step strategy: An ignition strategy in which the platform secures significant participation by one group and then secures participation by the other group by offering them access to the first group. Advertising-supported media typically do this by securing eyeballs first and then selling access to them to advertisers.

Platform Scale: How an Emerging Business Model Helps Startups Build Large Empires With Minimum Investment by Sangeet Paul Choudary

Hence, the platform needs to figure out a model that incentivizes the harder side to join in. 5.On-Boarding Of Two Distinct Markets. On many platforms, producers and consumers may be two distinct markets. The same user may upload and view videos on YouTube but the traveler and driver markets, on Uber, are largely distinct. The typical user, on these platforms, plays only one of the two roles. Serving two-sided markets requires reaching minimum traction on both sides. Hence, two-sided markets require building two companies, often with completely different challenges, not just building two forms of behaviors among users. FIVE DESIGN PRINCIPLES FOR SOLVING CHICKEN-AND-EGG PROBLEMS With the above characteristics in mind, a solution to any chicken-and-egg problem relies on five key design principles: 1.Finding A Compelling Bait To Start The Loop.The first step in breaking a vicious cycle is to find an inorganic bait that attracts and hooks one of the two roles without the need for the other role being present.

Over time, the platform spilled beyond the initial use case to accommodate many different use cases. MAKE A TWO-SIDED MARKET ONE-SIDED The micro-market strategy works especially well when both production and consumption functions can be performed by the same target user. On Facebook, the same user creates and consumes content. On Yelp, the same user base would create and read reviews. The platform can target a single closed market and guarantee interactions. However, this does not work as easily for platforms that need two different markets to come on board. In such cases, the best solution to the problem of getting two different roles onto a platform is to find an existing community or group of potential users that already contains both roles. Etsy, a niche marketplace for arts and crafts, figured an elegant solution to this problem. Etsy is a two-sided market of buyers and sellers.

Facebook’s launch at Harvard University, and subsequently in similar closed markets, ensured that critical mass was reached a lot faster than the many Myspace copycats that were launching globally around that time. 4.Incentivizing The Role That Is More Difficult To Attract.Some user types may require more incentive to be pulled in. Acknowledging this is important, and is counterintuitive to the principles of traditional marketing. And finally, 5.Staging The Creation Of Two-Sided Markets.In general, the nature of two-sidedness only allows us to capture such markets one side at a time. However, we do observe exceptions in the strategies that follow. Finding the bait or incentive that brings in one role and enables them to remain while we get in the other role holds the key to succeeding with this model. OpenTable used this strategy to get restaurants on board by providing restaurant management software (the bait) before any consumers signed up.

Companies that understand the economics of two-sided networks have prospered. For instance, credit cards provide a valuable service to both consumers and merchants. In theory, credit card issuers could charge both halves of this two-sided market. In practice, they sometimes do exactly that: charging annual fees to consumers and processing fees of 2% or more to merchants. In fact, in the early days, almost all card issuers charged their users for the privilege of using the cards. But increasingly, instead of charging the users, they give them away for free to maximize demand. That way, they make more money on merchant fees on the other half of the two-sided market. By lowering the annual fees and other user charges on their cards, credit card issuers can not only increase the market share of the cards, but also increase the attractiveness of their networks to merchants, as well as the associated processing fees.

Furthermore, platform owners can’t just focus on pricing. They have a variety of other levers to manage, including the user interface and user experience, reputation systems, marketing budgets, and core network technology. The most successful platform owners carefully curate the value that each side of the market gets from participating and aren’t too greedy. Once you understand the logic of two-sided markets, the next step is to apply it to multisided markets. Two-sided markets often become multisided markets with dozens or even thousands of distinct subgroups interacting through the platform. For instance, iTunes is a great way to get music on an iPhone. The more artists who put their music on iTunes, the more attractive it is to buy an iPhone. That’s a nice two-sided network. But the increase in iPhone sales not only makes iTunes more attractive to music artists; it also increases the value of the platform for developers Pandora, Waze, Uber, Lyft, Evernote, Clash of Clans, and every other mobile app.

This appears to be the case for rides in cars within cities. As Uber has lowered prices, first with UberX and then with UberPool (and perhaps eventually with self-driving cars), demand has expanded greatly.** Uber very much wants to satisfy this demand by charging extremely low prices, since doing so will maximize its revenue. Figure 8 Most demand curves are not straight lines. Sometimes, they have this shape. But in two-sided markets, simply working its way down the demand curve is only a small part of the story. To better understand Uber’s pricing decisions, let’s revisit some of the economics of networks first introduced in Chapter 6 when we discussed WhatsApp. Like WhatsApp, Uber benefits from network effects. But unlike WhatsApp, telephones, or faxes or many other networks, Uber is a two-sided network. Two-sidedness is at the core of many modern platforms.

Google and Facebook operate a form of what economists call “two-sided markets,” which Wikipedia defines as “economic platforms having two distinct user groups that provide each other with network benefits.” The original two-sided markets included things like credit cards where the issuer sits between vendor and customer in a single transaction. For platforms, the two sides are not part of the same transaction. Users are the source of data, as well as the product, but they do not participate in a transaction or in the economics. The advertisers are the customer and provide the market’s revenue. What makes the platforms comparable to traditional two-sided markets is that both sides depend on the success (or scale) of the market. At the scale of Facebook and Google, the two-sided market confers advantages that cannot be overcome by competitors, providing monopoly power.

FIGURE 13-1. The Inside Spread in RobertsonBooks.com Depending on the market, dealers may provide their quotes only on request, or they may quote continuous firm two-sided markets. Dealers in most corporate bond markets, and in some foreign exchange markets, quote only on request. Most organized quote-driven stock markets require that their registered dealers quote firm two-sided markets. For example, dealers in the Nasdaq Stock Market must continuously post firm prices at which they will trade. * * * ▶ The Inside Spread Charles, Cheryl, Goldie, Larry, and Teri are dealers in RobertsonBooks.com. Each quotes a two-sided market. Their quotes appear in table 13-1. Although each dealer’s bid/ask spread is 50 cents, the inside bid/ask spread is only 10 cents. Teri is the best bidder at 100.3 and Charles has the best offer at 100.4.

The realized spread is the difference between the prices at which dealers actually buy and sell. Realized spreads are usually smaller than quoted spreads because dealers occasionally trade at better prices than they quote and because they often adjust their bid and ask prices between trades. Dealers who quote both bid and ask prices quote a two-sided market. Their quotes make a market. Those who quote only one side quote a onesided market. Although most dealers will quote a two-sided market, they usually aggressively price only the side on which they would prefer to trade. For example, dealers who want to buy usually quote high (aggressive) bid prices to encourage sellers to sell to them. They also quote high uncompetitive ask prices to discourage buyers from buying from them. Dealers who want to sell quote low bid and ask prices.

Since the chooser will take the larger piece, the divider must try to divide the cake exactly in half to maximize his share. This solution is not entirely fair. The chooser has a slight advantage over the divider. If the divider cannot divide the cake exactly in half, a careful chooser will always take the bigger piece. The divider faces the adverse selection problem. When dealers quote two-sided markets, they divide the number line of possible prices into two parts. If they set their prices too low or too high, informed traders will take the more attractive side. To avoid adverse selection, dealers must set their bids below fundamental values and their offers above them. You can be confident that dealers offer fair prices when they quote tight bid/ask spreads before they know whether you want to buy or sell.


Trading Risk: Enhanced Profitability Through Risk Control by Kenneth L. Grant

For example, a portfolio that has a long position in corn and a short position in wheat is likely to be less risky, on a unit basis, than one that features dual longs or shorts in these same commodities. Similarly, an account that is long IBM and short Microsoft is likely to carry less exposure than one that contains the same securities held on the same side of the market. As portfolios scale up in size, the need to operate on both sides of a given market becomes more pronounced, and I strongly urge this kind of two-sided market orientation as being one of the best means of maximizing risk-adjusted profitability. However, I should tell you that this challenge is, in my experience, one of the most difficult in advanced portfolio management. This is because most traders and, indeed, most markets lend themselves more directly toward a single-sided market orientation. For example, it was plainly easier to trade the long side of the stock market in the last half of the 1990s, first, because the market enjoyed a sustained rally for the entire period; second, because the equity markets are structurally organized under all market conditions to favor long bets through such mechanisms as the “uptick rule” for short sales, the rather complicated “borrowing-based” mechanics of short selling, the rules that compel large institutional portfolios to operate exclusively on the long side of the market, and other factors.

As indicated earlier, by doing so, you reduce your exposure to broad-based market events, such as crashes. A portfolio that is entirely on one side of the market is exposed to the full fury of these episodes, which, as we have already discussed, are likely to cause all securities to move in lockstep with one another. Perhaps as important, Adjusting Portfolio Exposure (Rule 2) 137 the presence of some well-adapted two-sided market exposure will greatly enhance your ability to stay with your best ideas—across all market cycles—and thus capitalize in those situations when you feel a high level of conviction that a certain scenario will play out but less sure as to the precise timing. Let’s take a moment to more closely examine my assertion that a long/short position orientation also reduces the need to be absolutely accurate in terms of market timing, shall we?

Failing this, there’s always the opportunity to sell broad-based indexes, such as Standard & Poor’s (S&P) 500 futures, which will protect your position in some, if not all, of the types of situations that might otherwise force you to sell XTC before its time. If you are able to hold XTC through the approval process, you can call it a victory—irrespective of whether you liquidate your LSD, DRG, or S&Ps at a profit or at a loss. When viewed at a safely objective distance from the actual portfolio management process, it is easy to see how a two-sided market orientation, with one side serving largely as instruments of risk control, could offer better risk-adjusted returns than one that focused exclusively on either longs or shorts. Moreover, in these circumstances, it would be logical (and perhaps even in some cases desirable) that the aggregate P/L for the hedging side of the market would be negative. However, in my experience, these factors offer little direct solace to many portfolio managers who often feel the pain of losses on the hedging side much more acutely than they do when the ideas for which they have the highest level of conviction liquidate to negative P/L.

Firms like Google, Facebook and Amazon - and new ‘sharing-economy' firms like Airbnb and Uber - like to define themselves as ‘platforms'. They don't face a traditional market, in which the firm produces a good or service and sells it to a population of potential consumers. They operate, instead, in what economists call two-sided markets, developing the supply and demand sides of the market as the lynchpin, connector or gatekeeper between them. On the one side, there is a service offering to users. On the other side, there is a market offering to other firms - from sales to advertising space to information on users' behaviour. Firms have long operated in more than one market. The peculiarity of two-sided markets, however, lies in how the two sides are connected. As the number of users on one side of the market (using a search engine or joining a social network) rises, clicks on ads and information on consumers' behaviour also increases, boosting profitability in the other side of the market.

Rather, it is users who provide Google with necessary inputs for its production process: their looks on ads and, most importantly, their personal data. In return, they obtain online searches and other services. The bulk of Google's profits come from selling advertising space and users' data to firms. If something is free online, you are not the customer, you are the product.64 Facebook's and Google's business models are built on the commodification of personal data, transforming through the alchemy of a two-sided market our friendships, interests, beliefs and preferences into sellable propositions. The so-called ‘sharing economy' is based on the same idea. For all the hype about ‘sharing', it is less about altruism and more about allowing market exchange to reach into areas of our lives - our homes, our vehicles, even our private relationships - that were previously beyond its scope and to commodify them.65 As Evgeny Morozov has warned, it risks turning us all into ‘perpetual hustlers',66 with all of our lives up for sale, while at the same time undermining the basis for stable employment and a good standard of living.

Six firms (Facebook, Google, Yahoo, AOL, Twitter and Amazon) account for around 53 per cent of the digital advertising market (with just Google and Facebook making up 39 per cent).71 Such dominance implies that online giants can impose their conditions on users and customer firms. Many book publishers, for example, are unhappy with the conditions Amazon insists upon and are asking for better ones. But they have no leverage at all, because - as Evgeny Morozov puts it - ‘there is no second Amazon they can turn to'.72 The powerful network effects in the two-sided market have entrenched these companies' position. Companies like Google are de facto monopolies.73 But they are not recognized as such and have not attracted the kind of anti-trust legislation that large companies in more traditional industries - tobacco, autos, food - have done. The dominant position of a platform provider in core markets can then be used to favour their products and services in satellite markets, further extending the company's reach.

If, after reading Chapter 7, you’ve concluded that you’re running this kind of company, here’s what you need to know. In this model, the company makes money when a buyer and seller come together to complete a transaction. While eBay is undoubtedly the most famous example of a two-sided marketplace, the underlying pattern is fairly common. Consider the following business models, all of which have an aspect of a two-sided market: Real estate listing services allow prospective buyers to identify properties by a wide range of criteria, and then extract a fee for setting up the transaction, either as a one-time cost or a percentage. Indiegogo lets artists list projects and collect the support of backers. Backers are able to browse projects and find those they want to support. The site takes a percentage of monies raised.

Focus on the number of listings per seller and whether that’s growing, as well as the completeness of those listings (are sellers completing the description of their offering?). A bigger inventory means more searches are likely to yield results. If you start to saturate your marketplace (i.e., if most of the sellers in your market have already become members), then your growth will come from increasing their listings and the effectiveness of those listings. Buyer Searches In many two-sided markets, searches are the primary way in which buyers find sellers. You need to track the number of searches that return no results—this is a lost sales opportunity. For example, you might track the change in daily searches, new listings, and result counts, which will show you whether you’re growing the business (see Table 13-7). Table 13-7. Buyer searches month over month Feb Mar Apr May Jun Change in daily searches per buyer 103.3% 92.2% 116.4% 56.6% 80.6% Change in new listings per day 184.2% 139.6% 96.1% 69.6% 208.3% Change in average result count per search 147.6% 109.7% 123.5% 123.8% 175.0% In this example, buyers performed fewer daily searches in May and June than beforehand, relatively speaking.

The seller may set the minimum price, as well as a “Buy now” value, but the final price is what the market is willing to pay. If this is your model, you’ll need to analyze how many sales failed to receive a bid (indicating overpricing), how many sold for the “Buy now” price (indicating underpricing), and the duration and outcome of auctions. You might use this information to improve the prices your sellers set—and your resulting revenues. Key Takeaways Two-sided markets come in all shapes and sizes. Early on, the big challenge is solving the “chicken and egg” problem of finding enough buyers and sellers. It’s usually good to focus on the people who have money to spend first. Since sellers are inventory, you need to track the growth of that inventory and how well it fits what buyers are looking for. While many marketplaces take a percentage of transactions, you may be able to make money in other ways, by helping sellers promote their products or charging a listing fee.

Elimination of Stub Quotes The SEC did eliminate stub quotes, which were essentially placeholders for market makers that wanted only to quote one side of a market. Typically, stub quotes were placed far away from the market, often as low as one penny for a bid. For example, if a market maker wanted to place an offer to only sell stock, he would have to place a stub quote as a bid to create a two-sided market. When Accenture traded at $0.01 during the Flash Crash, the bid that was hit was a stub quote. According to the SEC Flash Crash report, “Executions against stub quotes represented a significant proportion of broken trades on May 6.”14 Eliminating stub quotes was a no-brainer in our opinion. What is needed, however, are more stringent market maker obligations. Currently, market makers need to quote within only 8% of the NBBO for most securities.

33 Kaufman was eerily prescient when he said in early autumn 2009, “Moreover, unlike specialists and traditional market-makers that are regulated, some of these new high frequency traders are unregulated, though they are acting in a market-maker capacity. They have no requirements to ‘maintain a fair and orderly’ market. They trade when it benefits them. If we experience another shock to the financial system, will this new (and dominant) type of pseudo market maker act in the interest of the markets when we really need them? Will they step up and maintain a two-sided market, or will they simply shut off the machines and walk away? Even worse, will they seek even further profit and exacerbate the downside?”34 Zero Hedge was relentless, publishing scores if not hundreds of posts in the year leading up to the crash criticizing HFT and the stock market and predicting a high-speed market meltdown. A few weeks before the crash, on April 16, 2010, I submitted a comment letter on the SEC’s Concept Release.35 I wrote that “Formal and informal market makers in the equities markets today have few or none of the responsibilities of the old dealers...firms shed responsibility for price continuity, quote size, meaningful quote continuity or quote depth...

Stocks would have to be traded by real market makers with obligations to supply capital at all times. These market makers would have affirmative and negative obligations. They would have to supply real liquidity, not phantom liquidity, and they should not interfere when the market is working without their assistance. 2. There must be minimum quote sizes based on the market cap of the stock and a minimum order life on all orders. 3. To reward market makers for creating a more stable two-sided market, there also needs to be a minimum spread that is wider than a penny. No doubt, our critics will claim that this alternative is going in the wrong direction. They will say it is a step backward and will bring back all the problems that we had with the old NYSE specialist and NASDAQ market maker systems. They will say that technology has moved us forward and made the markets more efficient.

Of course, there may be other traditional economies of scale that could lead to the eventual dominance of one or two firms because of several circumstances—by getting drivers to sign on and retaining them; or learning by doing in launching in a new market; or learning by doing in dealing with local regulators. 26. A transcript (from panel 4) of the workshop, titled “The ‘Sharing’ Economy: Issues Facing Platforms, Participants, and Regulators,” is available at https://www.ftc.gov/system/files/documents/videos/sharing-economy-workshop-part-4/ftc_sharing_economy_workshop_-_transcript_segment_4.pdf.

This is because unlike local transport, short-term accommodation is sought primarily by travelers rather than by local residents. You favor a platform that can get you accommodation anywhere in the world, rather than one that specializes in one city. Thus, on the Airbnb platform, network effects are more resilient. In a sense, the “fractal” structure of the network effects in both these examples makes their economics more complex than those of traditional two-sided markets, potentially making them either stronger or weaker. As I discuss in chapter 6, there are a number of new regulatory challenges raised by the emergence of the sharing economy. One that I do not discuss relates to the question of market power. This is because deepening our understanding the nature of these new network effects, or asking the question framed by Professor Maurice Stucke when he spoke at a June 2015 Federal Trade Commission panel about regulating the sharing economy—“Do I have the analytical tools to assess what the impact would be?”

Platform infrastructure While we will return to the concept of ‘platforms’ in detail in chapter 2, it is worth noting how important platform infrastructure is as a precondition to the gig economy. The basic idea in the architectures of platforms that mediate work is to create a digital context in which buyers of labour power are able to connect with sellers of labour power (what economists call a ‘two-sided market’). Uber’s platform connects people who want a taxi ride with people who are willing to provide taxi rides. Fiverr’s platform connects people looking for a graphic designer or video editor with people offering those services. Unlike older ways of connecting buyers and sellers of work, digital platforms make much of the process relatively seamless for both parties. On many platforms, it only takes a few minutes for a client seeking a service to issue a request through the platform, connect to a worker, and the worker to begin to perform that service.

Multiple gig economy models have emerged, ranging from general online freelancing platforms, which are necessarily limited in the amount of control that they can exert on work, to transportation and care work platforms, which are characterized by extremely high levels of explicit coordination and power asymmetry. But what all gig economy models have in common is a defining logic that seeks to shift maximal risk and minimal reward onto workers. Platform companies achieve this through technologies and infrastructures of connectivity that allow work to be organized via two-sided markets, political environments that impose few regulations, a zeitgeist that values flexibility, and a backdrop of increasing inequality that leads ever more workers to make the calculation that a bad job is better than no job. The gig economy is big, and around the world there are powerful interests who only seek to make it bigger. Yet nothing about the gig economy is inevitable. If we want to make sure that we avoid yet another industry in yet another place becoming organized by the logics of the gig economy, then we all have a part to play in resisting some of its worst characteristics.

In a speech on September 14, 2009, the anniversary of the collapse of Lehman Brothers, Ted warned of a flash crash and how HFT would fuel it: [U]nlike specialists and traditional market-makers that are regulated, some of these new high-frequency traders are unregulated, though they are acting in a market-maker capacity. They have no requirements to “maintain a fair and orderly” market. They trade when it benefits them. If we experience another shock to the financial system, will this new, and dominant, type of pseudo market maker act in the interest of the markets when we really need them? Will they step up and maintain a two-sided market, or will they simply shut off the machines and walk away? Even worse, will they seek even further profit and exacerbate the downside? One problem we faced—and one you may be experiencing as you read this chapter—is that HFT isn’t just mind-boggling. It’s mind-numbing. Senator Kay Hagan (D-NC), a fellow freshman who’d become Ted’s friend, was presiding in the chair on the day Ted gave the above speech.

Regulators’ lack of understanding of HFT strategies and the volatility they create left the markets vulnerable to a nausea-inducing plunge. For example, the SEC took for granted that high-frequency traders were the new market makers without taking into account the ways in which they differed from traditional market makers. Not only did the speed of HFT algorithms cripple the markets in a matter of minutes, but the absence of true market makers to guarantee two-sided markets in times of high volatility created an enormous liquidity shortage. Andrew Haldane, executive director for financial stability for the Bank of England, said that the flash crash demonstrates that HFT is “adding liquidity during a monsoon and absorbing it during a drought.” Although circuit breakers may make a crash less calamitous, they’re not a cure for regulatory ignorance. Third, the lack of data made identifying the causes of the flash crash a monumental task.

User scorecards determine which is the most effective. Sometimes, seemingly tiny differences can mean a lot. Something as simple as the color or size of a type font may profoundly impact the willingness of consumers to engage, triggering behavioral variations that may be worth tens of millions in revenue. Now Microsoft had to master this new approach to product design. Third, we had to be great at understanding and building two-sided markets—the economics of a new online business. On one side are the consumers who go online for search results, and on the other side are the advertisers who want their businesses to be found. Both are needed to succeed. This creates the auction effect I was describing earlier. Both sides of the business are equally important, and designing the experience for both sides is crucial. Attracting more and more searchers obviously makes it easier to attract more and more advertisers.

For example, suppose the candidates Elaine and Saeed have the following ranked list of residencies (ignore the annotating characters for now, which we discuss shortly): Elaine Saeed Harvard Cornell Johns Hopkins UC San Diego @ UC San Diego & Harvard # Baylor Johns Hopkins Based on application materials and interviews, the schools of course also have their own ranked lists of candidates, such as: Harvard UC San Diego Saeed # Roger Elaine Saeed @ Roger Elaine & Gwyneth Mary So this is a two-sided market—candidates and hospitals—and there are also capacity constraints, because each candidate can of course take only one residency, and each hospital can only take a limited number of residents (which for simplicity we’ll assume is also just one). Thus, as with dating and commuting, we once again have a large system (many thousands of applicants, and hundreds of schools) of interacting, competing preferences and would like to specify a desirable solution—and a fast algorithm for finding one.

Micropayments make the transaction about content, rather than about creators, but because there is so much freely available, highly substitutable content they create decision fatigue for consumers.362 Subscription models can operate like a freemium model, but they get even more interesting as a two-sided market. In a freemium model, a creator gives away some of their content for free, but restricts other content to those with paid subscriptions. The free content helps creators grow their reputation via public network effects. In a two-sided market, paying subscribers subsidize all of the content for nonpaying readers, under the assumption that creators aren’t actually selling content but a sense of membership and identity. Instead of charging, say, all 100,000 readers ten cents to read an article, creators can instead give away the article for free, but charge 1,000 extra-dedicated subscribers ten dollars per year.

Chien, “Patent Assertion and Startup Innovation” (Santa Clara University of Law Legal Studies Research Paper Series 26-13, 2013). 35.Chicago economists defend these anti-competitive practices by saying that these restraints are just the natural way that efficient competition takes in two-sided markets. According to these economists, two-sided markets are just a “meeting place”—today, typically an electronic platform—for two sets of agents to interact with each other. Credit cards bring together customers with stores. They argue that courts shouldn’t interfere with the workings of markets. To say that these arguments ignore the actual workings of the marketplace is an understatement. Nevertheless, with these arguments, they succeeded in persuading some courts—including the US Supreme Court in another one of its five-to-four split decisions—to allow these abuses of market power to continue. For an excellent discussion, see Benjamin E. Hermalin and Michael L. Katz, “What’s So Special About Two-Sided Markets?” in Martin Guzman, ed. Toward a Just Society (New York: Columbia University Press, 2018), 111-130. 36.The contract provisions are so strongly anticompetitive that even a firm with a small market share (like Discover Card) could and did charge exorbitant prices, far in excess of costs.

Two liquidity measures are calculated: the percentage of time that traders of each group provide two-sided liquidity, and bid–offer spread compiled on a one-second grid and averaged over 10-minute time intervals, with USD/JPY, EUR/JPY currency pairs for BOJ intervention, and EUR/CHF, USD/CHF currency pairs for SNB intervention. The BOJ intervention at 01h00 GMT on August 4, 2011, caused a sharp jump in the USD/JPY exchange rate that did not disrupt the two-sided market. MTs provided liquidity 100% of the entire intervention time, while HF traders and slow AI failed to provide two-sided liquidity only for two seconds and eight seconds, respectively.

The SNB intervention on September 6, 2011, lasted for 30 minutes, from 08h00 to 08h30 GMT. Liquidity provided by slow AI users for the USD/CHF exchange rate had notable gaps prior to the SNB intervention. The intervention briefly decreased the percentage of time for which all customer groups quoted two-way prices. HF traders were the quickest, while UHF traders were the slowest in restoring the two-sided market. HF traders were the most active in setting the bid–offer spread during and after the intervention. For the EUR/CHF exchange rate, MTs and HF traders were the best liquidity providers during the SNB intervention. While the SNB intervention affected the EUR/USD exchange rate, its liquidity was not impaired. These two events suggest that high-frequency traders can be valuable contributors to market liquidity during dramatic price moves of exchange rates, such as during central bank interventions.

Sometimes these jobs are given heft as harbingers of the “Second Machine Age” or the “Fourth Industrial Revolution” or part of a larger digital or platform economy. Other times, they’re simply, glibly called gigs.9 No employment laws capture the on-demand gig economy’s odd mix of independence from any single employer and dependency on a web-based platform. As the taskmasters of the gig economy, on-demand platforms make their money by matching those buying and selling human labor online, generating a two-sided market of myriad businesses and anonymous crowds of workers. And, importantly, as media scholar and sociologist Tarleton Gillespie points out, platforms may not create the content that they host, “but they do make important choices about it.”10 On-demand work platforms can easily become silent business partners more aligned with the interests of those willing to pay a fee to find workers than with the workers searching for jobs.

Since 2015, companies buying and selling on-demand work have tiptoed cautiously around any activity that makes them look as if they are doing anything other than providing an online meeting place and matching service between people with jobs to be filled and workers willing and able to work. On-demand ghost work platforms see themselves as neutral parties, arguing that they are the software serving as the middlemen managing what economists call a two-sided market. They connect requesters seeking workers, on one side of the platform’s marketplace, and workers seeking jobs, on the other side. And in the absence of set hours, work sites, or agreement about who’s the official boss in charge, it is difficult to gauge how much ghost work is done across this burgeoning industry, who’s paying for it, and which workers are completing the tasks. The transaction costs that economist and Nobel laureate Ronald Coase so long ago identified as the reason for the very existence of firms seemed to melt away with the new on-demand systems.

When the ability to innovate is present, the incentive to innovate is driven by the desire to appropriate financial gains associated with innovation. This economic framework is “often associated with the eminent economist Professor Joseph Schumpeter,” who suggested, “firms with market power will have the greatest incentive to innovate because of their large relative size and dominant position in a market” D. L. Weisman and R. B. Kulick, “Price Discrimination, Two-Sided Markets, and Net Neutrality Regulation,” Tulane Journal of Technology and Intellectual Property 13 (2010): 81, https://www.researchgate.net/profile/Dennis_Weisman /publication/228307995_Price _Discrimination _Two-Sided _ Markets _ and _Net _Neutrality_Regulation/links/0deec5187eadf2a5c8000000.pdf. 7.

Josh Wright, “Price Discrimination Is Good, Part I,” Truth on the Market (November 30, 2008), http://truthonthemarket.com/2008/11/30/price -discrimination-is-good-part-i/. This approach, generally associated with Nobel laureate economist Kenneth Arrow, suggests “the increased business generated by an innovation will come mostly from sales that formerly would have gone to competitors, while monopolists may largely cannibalize their own business”; Weisman and Kulick, “Price Discrimination, Two-Sided Markets, and Net Neutrality Regulation.” 8. “The reason why price discrimination may intensify competition is that with uniform pricing, firms would only compete for ‘marginal consumers’ whereas through price discrimination, firms can compete for all customers, including those with strong loyalty to a competitor’s brand”; Papandropoulos, “How Should Price Discrimination Be Dealt with by Competition Authorities?”

In lowactivity securities, though, the potential dealer’s costs of continuously monitoring bids and offers may be too large to recover from the relatively infrequent trades. In these instances, continuous liquidity requires that a dealer be designated as such (by the market authority) and provided with additional incentives. Perhaps the best-known designated dealer is the NYSE specialist. The specialist has many roles and responsibilities, but an important one is maintaining a two-sided market when there is nothing on the limit order book and no one else on the floor bidding or offering. Establishing the proper incentives for designated dealers, though, has proven to be difficult. The issues involve measuring the liquidity that the dealers provide, determining the beneficiaries of this liquidity, allocating the costs, and balancing the rights of dealers against the public TRADING MECHANISMS users of limit orders (who are usually the dealers’ direct competitors).

There are two closely related challenges to the on-demand economy’s claim to have fostered a revolutionary culture of innovation: first, that many of its supposedly innovative elements are, in fact, simply aimed at entrench- ing existing operators against future competitors; and second, that platforms’ business models might in fact disincentivize the investment in research, development, and working conditions that spurs innovation. Pernicious Innovation Take rating algorithms as an example. The dramatic increase in information available about workers and consumers alike has gone a long way towards alleviating the information asymmetries that traditionally plague two-sided markets. The case for productivity-enhancing innovation looks straightfor- ward: extensive information allows for easy matching of supply and demand, increasing service provision for platform users, and income for workers. Upon closer inspection, however, not all is quite as it seems. As we saw in the previous chapter, two of the most important functions of algorithmic * * * 88 The Innovation Paradox ratings are to control workers—and to lock them into a particular app’s ‘eco-system’: ratings need to be built up over time and cannot be taken from one platform to another.

Instead, they ended up hosting a forty-five-year-old father from Utah, a thirty-five-year-old woman from Boston, and a thirty-year-old Indian man. Brian and Joe realized this market might be bigger than they first thought. They soon launched Air Mattress Bed & Breakfast, later Airbnb. Airbnb is among the most successful of the shared-economy companies. Unlike many traditional businesses, shared-economy companies have no single base of customers. Rather, these companies provide two-sided markets that connect sellers (or people with something to share) with buyers (who are willing to pay for the product or service)—like the transportation-network company Lyft, which connects passengers who need a ride to drivers who have a car, and TaskRabbit, an errand-outsourcing company that connects people who need something done with “taskers” who will do the job. For Airbnb, it’s connecting local residents with room to spare and travelers who need a place to stay.

Investment Insights Although track records are an essential component in making investment decisions, their routine use and superficial interpretation can lead to erroneous, and even completely misleading, conclusions. The key question an investor needs to ask is whether the implications of the past track record are pertinent for the future. It some cases, they will not be. For example, the track record of an equity hedge manager that coincides with a bull market may not be at all indicative of how the manager could be expected to fare in a more two-sided market, let alone a bear market. In some cases, a good track record may reflect excessive risk taking in a benign environment rather than manager skill. In order to assess the relevance of a past track record, an investor needs to understand the source of the past gains and the risks taken to achieve them. 1 Of course, many credit-based managers did well during 2003–2007 without taking on excessive credit risk exposure.

ITunes was an entire ecosystem of apps constructed on the capabilities built into the phone, and it boomed. Since Apple kept adding ingenious new ways to interact with the phone, including new sensors such as a camera, GPS, and an accelerometer, thousands of novel species of innovations deepened the iPhone ecology. A third generation of platforms further expanded the power of the marketplaces. Unlike traditional two-sided markets—say, a farmers’ market that enables buyers and sellers—a platform ecosystem became a multisided market. A good example of this is Facebook. The firm created some rules and protocols that formed a marketplace where independent sellers (college students) produced their own profiles, which were matched up in a marketplace with their friends. The attention of the students was sold to advertisers.

173 I imagine there would be mass protest and a slew of lawsuits. The very possibility seems antique, the fever dream of a robber baron. But in the digital realm, monopolistic cable firms are angling to impose a similar arrangement: to make Internet access cheap if paired with their own content, and pricier if used to access others’ work. Similarly, firms like Google and Amazon are in prime position to make money off both sides of a two-sided market: monetizing our data and purchases, while promoting to us their own products and ser vices, or those of “partners” who let the larger platform share in their profits. That’s one reason we need to look back to the legal principles that animated Populists and Progressives in response to America’s first Gilded Age. The great Internet companies and the physical networks that enable them are not the first private enterprises to achieve near monopolistic power over a key ser vice, and to leverage that power into windfall profits and influence.174 It happened in the nineteenth century with railroads and telegraphs.175 Like today’s search and cable companies, those fi rms controlled essential junctions of an emerging economic order.
