COMMUNICATION: The process by which ideas, thoughts, and subsequent feedback is accomplished through encoding, sending, and decoding. In order for effective communication to occur the sender must understand the target audience and encode the message in a way that will be understood. This message is sent in various forms and can be distorted by interference prior to reaching the receiver. Receiver then interprets the message and performs required action and gives necessary feedback to the sender. Utilizing this process correctly is an integral part of the promotion element in the marketing mix.

- It's quite useful to identify or measure the degree of concentration in an oligopoly market. This is generally accomplished in one of three ways.

- Concentration Ratio: This measure of concentration combines the market shares for the largest number of firms in an industry to indicate the degree of market concentration.
- Herfindahl Index: The Herfindahl index includes the market shares of all firms in the market.
- Consideration and analysis of concentration using either of these three measures is really only relevant for oligopoly.
