Understanding Market Dynamics in Multi-Sided Platforms
The episode highlights the key concepts in E. Glenn Weil's paper on pricing in multi-sided platforms, emphasizing the idea that these platforms are not merely matchmakers, but also active market shapers. Weil challenges the common assumption that platforms solely benefit from network effects, arguing that monopolies can distort these effects through their pricing strategies.

This critical insight pushes researchers and practitioners to consider the diverse characteristics of platform users when discussing market dynamics.
