Definitions:

Oligopoly

A market structure characterized by a small number of firms dominating the market, often leading to limited competition.

Monopolistic Competition

A market structure characterized by many firms offering products or services that are similar but not perfect substitutes, leading to each firm having some market power.

Differentiated Products

Goods or services that are distinguished from others based on quality, features, or brand, making them non-identical and often allowing for market power.

Monopolistically Competitive

A market structure where many firms sell products that are similar but not identical, allowing for some degree of market power and product differentiation.
