Recent advances in communication technologies have altered the scope, speed, and structure by which information is exchanged among humans. These new patterns of information exchange are altering the dynamics of belief formation, with repercussions for politics, culture, and more recently, asset valuation. A recent example are so-called “meme-stocks,” whose institutional valuations are challenged by valuations driven by alternative “social media based” narratives. The rise of these alternative valuations can increase asset price volatility.

This meeting will continue a discussion that began in the 2020 SFI-UBS Risk Meeting on Beliefs, Narratives, and Market Structure. Focal topics include: (i) the dynamics through which beliefs form, (ii) new technology-driven processes through which ideas spread, and (iii) implications for asset valuation and risk.
