CIPS Updated L4M5 Exam Questions and Answers by nella

An adversarial style is appropriate when issues are non-negotiable, such as health and safety commitments (D). In these scenarios, compliance is required without compromise, and a firm stance may be necessary.

A monopoly exists when only one company can supply an essential product or service in a given region because of significant barriers to entry for any competitor. The barriers can be legal, regulatory, economic, or geographic. Ma Bell case is an example of monopoly. The company was broken up in 1982.

A monopsony is a market structure in which a single buyer substantially controls the market as the major purchaser of goods and services offered by many would-be sellers.

Pure or perfect competition is a theoretical market structure in which the following criteria are met:

- All firms sell an identical product (the product is a "commodity" or "homogeneous").

- All firms are price takers (they cannot influence the market price of their product).

- Market share has no influence on prices.

- Buyers have complete or "perfect" information—in the past, present and future—about the product being sold and the prices charged by each firm.

- Resources for such a labor are perfectly mobile.

- Firms can enter or exit the market without cost.

Monopolistic competition is closely related to the business strategy of brand differentiation
