What does information density refer to?

Information density refers to the total amount of information available to all market participants. This concept emphasizes the extent and richness of information in a given context, particularly in markets where consumers and producers can access a wide range of data about products, pricing, and services. Information density is significant in digital commerce and information technology, as it enables participants to make more informed decisions, fostering competition and enhancing the efficiency of the market. The greater the information density, the more consumers can understand their options and the market dynamics, which often leads to better choices and outcomes.

In contrast, while the complexity and content of a message is important in communication, it specifically addresses how rigorous or nuanced a piece of information is, rather than the breadth of information available. The total amount of information delivered by merchants focuses more narrowly on specific transactions or communications rather than the overarching landscape of available market information. Lastly, although reducing price transparency is a valid concern in some market contexts, it relates more to the application and effects of information rather than the concept of information density as a measure of the total available data.
