In economics, private information refers to knowledge that is not available to all market participants. When consumers possess specific insights about the quality of a product, it can influence their purchasing decisions and affect the overall market outcome.

For instance, if certain consumers know that a product is of exceptionally high quality, they may be willing to pay a premium for it, potentially creating a market where the prices reflect this hidden information. Conversely, if other consumers lack this knowledge, they may undervalue the product, leading to distortions in the price and quantity sold in the market. This situation creates an information asymmetry, where one party has an advantage (those who know the product quality) over the other (those who do not), which can lead to market inefficiencies and affect competition among sellers.

In contrast, when all firms know their competitors' prices, or if everyone has access to the same sales data, there is a level of transparency in the market that does not permit private information to exert the same influence. Likewise, government regulations applying uniformly across industries would standardize the playing field, minimizing the impact of
