Elements of value exchange

PLATFORM

A PLATFORM: • Is a nexus of rules and

architecture• Is open, allowing regulated

participation• Actively promotes (positive)

interactions among different partners in a multi-sided market

• Scales much faster than a pipeline business because it does not necessarily bear the costs of external production.

• Businesses can be very complex• Rapid growth may preclude trial-and-error• Network effects = winner often takes most/all

• Successes: Windows, Adobe, iPod/iPhone, Alibaba, LinkedIn, Facebook, etc.• Failures: Betamax, IBM OS/2, Amazon auctions, eBay Japan, MusicNet, N-Gage,

Blackberry, etc.

Distinctive Challenges


• Network effects are demand-side scale economies. Rising network effects increase existing and prospective users’ willingness-to-pay (willingness-to-participate)

• Supply-side scale economies are realized when firms reduce unit costs by leveraging fixed costs or experience effects. With high fixed costs and low unit costs, average costs decline with volume.

• Many businesses that exhibit network effects also enjoy strong supply-side scale economies • However, demand-side and supply-side economies are conceptually distinct: unit cost reductions

that result from network growth should not be labeled network effects

A TWO-SIDED NETWORK HAS FOUR NETWORK EFFECTS

Side1

PLATFORM

• A same-side effect for each side, i.e., preference regarding number of other users on own side

• A cross-side effect in each direction, i.e., preference regarding number of users on other side

A TWO-SIDED NETWORK HAS FOUR NETWORK EFFECTS. THESE CAN BE POSITIVE OR NEGATIVE.

Side2

Side1

PLATFORM

+ same-side : Player-to-player contact in Xbox MMOG, end-user PDF sharing.

+ cross-side : merchants & consumers for Visa, developers & end-users for Windows

- same-side : competing suppliers in Covisint auction, competing dates on Match.com

- cross-side : Digital Rights Management costs to consumers. Advertising clutter to viewers.

You must manage all such interactions

1. Large Supply/Demand Effects (Utilities & Facebook vs Consulting). Costs fall or value rises with volume.

2. Large Multi-Homing Costs (OS vs credit cards). Consumers tend to choose just one

3. Niche specialization is low (geographically unrestricted courses vs geographically restricted courses). Differentiation creates protected markets not swamped by scale economies.

TO PRICE A PLATFORM WITH NETWORK EFFECTS, WHO GETS THE SUBSIDY?Answer: The side that is the stronger attractant (or that creates more value)

The Story of Acrobat Reader/WriterAdobe first tried to sell PDF readers and writers but no one wanted to buy readers when there was no content to read. And, no one wanted to buy writers when no one had readers. Adobe broke the logjam by giving PDF readers away.

Adobe Acrobat: SUBSIDIZE CONSUMERS

Making PDF readers free dramatically increased the value of PDF writers, shifting producer demand out and to the right. Here, Adobe subsidized consumers. Profit lost on one side of market is more than made up by profit gain on other side of market.

Operating Systems: Subsidize Developers

Making System Development Toolkits (SDKs) free dramatically increased the value of operating systems, shifting consumer demand out and to the right. Here, Microsoft subsidized producers. Profit lost on one side of market is more than made up by profit gain on other side.

WHEN DOES FREE MAKE SENSE?

1) People understand the razors & blades strategy (same as cellphones & minutes, printers & ink)

Give away one thing, charge for anotherThe SAME person gets both items

2) People often misunderstand 2-sided network pricingSubsidize one party in order to attract then charge another partySubsidy side and money side of the market are DIFFERENT parties (like women & men on ladies’ nights)

3) Monetization is trickier for 2-sided networksCharging the wrong side (or both) reduces growth and network effects

ISSUES

Q: Why is price more important in network markets?A: The entire demand curve can change with price.

Q: Why is price more strategic in 2-sided networks?A: Imagine competing on the subsidy side – you need a source of subsidy at least as great.


TAKEAWAYS FROM CHAPTER TWONetwork effects are the main source of value creation and competitive advantage in a platform business—and, increasingly, in today’s economy. Whereas giant industrial-era firms were made possible by supply economies of scale, today’s giants are made possible by demand economies of scale—expressed as network effects.

Network effects are not the same as price effects, brand effects, or other familiar growth-building tools.Frictionless entry and other features of scalability maximize the value-building impact of network effects.A two-sided market (with both producers and consumers) gives rise to four kinds of network effects: same-side effects (consumer-to-consumer, producer-to-producer) and cross-side effects (consumer-to-producer, producer-to-consumer). Polarity on any of these can also be positive or negative. A growing platform business must manage all four.The key to minimizing most negative network effects is quality curation and minimizing congestion, which increases the chances of a happy match between producer and consumer.
