Study Notes

Platforms: Definitions and Typology

Platforms are entities that bring together economic agents, manage network effects among them, and generate economic value.
Platforms are "managers of network effects."
Network effects arise when a product or service's value depends on other users' consumption decisions.
Positive network effects occur when a product or service becomes more valuable as more people use it.
Negative network effects occur when a product or service becomes less valuable as more people use it.
Network effects can be classified into two main categories: same-side and cross-side.
Same-side network effects occur when an agent's decisions about how much to interact on a platform affect the well-being of other agents in the same group.
Cross-side network effects occur when an agent's decisions about how much to interact on a platform affect the well-being of other agents in a different group.
Examples of same-side network effects: an increase in the number of users leads to more communication possibilities and increased value for everyone.
Examples of cross-side network effects: an increase in end-users on a platform leads to a higher value for app developers, which leads to more apps, and then a higher value for end-users.

Platform vs. Pipeline

Pipelines create value linearly with centrally employed staff and owned assets. Transactions are controlled.
Platforms create value by facilitating interactions between external providers and consumers. Transactions are enabled.
Platforms actively manage network effects, while pipelines do not.

The Importance of Network Effects

Network effects generate feedback loops: The higher the activity level of a group, the more attractive it becomes for members to increase their activity level, leading to a further increase in the group's overall activity level.
Platforms are not specific to the digital economy: Examples of digital platforms and their "brick-and-mortar" equivalents include:
- Marketplaces: Online marketplaces vs. physical markets
- Professional networks: LinkedIn vs. professional associations
- Social networks: Facebook vs. communities
Digital technologies have considerably reduced transaction costs: mainly costs associated with coordination of needs and trust issues. This has led to a significant increase in the number of platforms in the digital economy.

Examples of Platforms

Original Facebook: Platform, same-side network effects are present, actively managed.
Wikipedia: Platform, same-side network effects are present, actively managed.
Uber: Platform, cross-side network effects are present, actively managed.
Esperanto: Not a platform, same-side network effects are present, but not actively managed.
Aldi: Not a platform, no network effects are present, not actively managed.
Tesco: Potentially a platform, cross-side network effects are present, but not actively managed.
Individual blog: Not a platform, no network effects are present, not actively managed.
Group or ad-financed blog: Platform, cross-side network effects are present, actively managed.
Petrol stations: Not a platform, no network effects are present, not actively managed.

Amazon's progression from 1994-2001 to today:
- 1994-1996: Amazon was a pure reseller with no network effects, not a platform.
- 1996-2001: Amazon became a one-sided platform with same-side effects on the buyer side.
- 2001-Today: Amazon became a two-sided platform with cross-side effects between sellers and buyers.

Regulation Issues

Expectations matter! - The context and expectations surrounding platforms are important for understanding their economic impact.
Regulation issues: Existing regulation may need to be adapted to address the unique features of platforms.
