Perfect Information
In the parlance of economics, perfect information (AKA “no hidden information”) is a feature of perfect competition where the consumer and producers have the same instantaneous knowledge of crucial market information at any given time.
While in #Game Theory, a sequential game is considered perfect information (not to be confused with Complete information) if each player are perfectly informed of all the events that have occurred or is occuring, e.g. chess.
On the other hand, a situation where some events are not available to other participants is an example of an imperfect information game, e.g. poker.
