Regarding the secrecy in pricing: At that elite level of the 'high' contemporary art world, it is essentially a practice of unregulated insider trading, a Ponzi scheme for the chosen few, protecting and increasing the demand and value of their portfolio of exclusive artists as long as the bubble lasts. I don't think those power brokers want to open it up to all-access market expansion.
Thanks for this article. I will follow. Who else on Medium is writing about the contemporary art world, or "art industry" as I relunctantly, but more accurately, perfer to call it?
