There is a rich literature in accounting that takes a critical perspective to market transparency, focusing on the nuances and boundaries. For example, some researchers question its utility (e.g. Etzioni). This also connects to the performativity of quantitative models or "reacitivity." Specific cases include transparency in the art market. There are also studies from finance that note concerns with market transparency, such as perverse effects including decreased market liquidity and increased price volatility. This is one motivation for markets that are selectively transparent, such as "dark pools".
