Marketplace Liquidity: How Side Switching Can Help in Online Education

In the world of marketplaces, achieving liquidity is crucial for success. Liquidity refers to the critical mass of demand and supply within a marketplace. It is easier for one-sided networks, such as social networks like Facebook, to achieve liquidity because the same users represent both demand (content consumption) and supply (content creation). The liquidity of any network is determined by the number of users and the density of connections between them.

For marketplaces, these connections link demand with supply, and therefore, liquidity depends on the number of suppliers that can be matched with a given customer request. Supply density, which can be measured by the ratio of match-able supply to demand within a region or category, plays a significant role in achieving liquidity.

Different marketplaces have different characteristics that affect their liquidity. Hyperlocal marketplaces, like Uber, need to maintain a specific supply to demand ratio within a small radius to achieve their targeted wait time. This requires significant investments in field operations. On the other hand, marketplaces like Airbnb, which have cross-border network effects, need to maintain a specific supply to demand ratio within a destination, but can spread it across a larger geographic area.

Supply density also varies based on the nature of supply. Uber has commoditized or interchangeable supply, where riders are looking for on-demand transportation and are not sensitive to the brand or identity of the driver. This makes it easier for Uber to acquire a critical mass of supply across a few categories. However, marketplaces with differentiated supply, like Airbnb, face challenges in acquiring a critical mass of supply across numerous categories. This complexity makes Airbnb more defensible but also poses liquidity challenges.

The characteristics that make marketplaces defensible and scalable also impact their ease of reaching critical mass. Marketplaces with commoditized supply and cross-border network effects face the lowest hurdles to liquidity, while hyperlocal marketplaces with differentiated supply face the most challenges.

In the absence of deep pockets, hyperlocal marketplaces with differentiated supply have two options to achieve liquidity. One approach is to use a "come for the tool, stay for the network" strategy. Another approach is to rely on "side switching," where marketplace participants can switch between being buyers and sellers. This is similar to what happens on social networks, where users act as both demand and supply.

To maximize the liquidity advantage from side switching, marketplaces need users to switch frequently between the demand and supply sides. This requires embedding side switching as a core part of the marketplace's value proposition. Poshmark is an example of a marketplace that has successfully implemented side switching.

Moving beyond marketplaces, the concept of content generation has taken a different turn in the realm of online education. More access to cheap and abundant content does not necessarily translate to more engagement or better learning outcomes. Massive open online courses (MOOCs), which offer recorded videos with a defined syllabus, have low completion rates.

This has led to the rise of cohort-based courses (CBCs) in online education. CBCs are interactive online courses where a group of students advances through the material together, with hands-on, feedback-based learning at the core. CBCs focus on higher-order skills and provide accountability through bi-directional learning between instructors and students.

Studies have shown that interactive processing, where students engage in interaction with partners or teammates over the content, is the most powerful approach to comprehension and retention. Cohort-based courses provide this interactive processing and create a sense of accountability through knowledge exchange between instructors and students.

Another effective learning approach is interleaving, where instructors mix different topics, ideas, and activities together during study. This forces students to switch between them intentionally, resulting in better learning outcomes.

Cohort-based courses also provide an opportunity for creators to monetize their expertise directly and without requiring a large volume of content creation. Traditional social platforms often create a division between monetization activities and community building. Cohort-based courses offer a way for creators to monetize their expertise while also building a community. This productized offering provides leverage in terms of creator time and effort.

In conclusion, achieving liquidity is crucial for marketplaces and cohort-based courses alike. Marketplaces can benefit from side switching to increase liquidity, while cohort-based courses offer a more engaging and accountable learning experience. By understanding the unique challenges and strategies of each, marketplaces and online education platforms can optimize their approaches to achieve success.

Actionable advice:

1. For marketplace startups with hyperlocal and differentiated supply, consider implementing a "come for the tool, stay for the network" approach or leveraging side switching to bootstrap liquidity.
2. For online education platforms, explore the potential of cohort-based courses to provide interactive and accountable learning experiences that go beyond content consumption.
3. Incorporate interleaving and interactive processing techniques in online education to enhance comprehension and retention for students.
