The larger the number of firms and the less the degree of product differentiation, the greater will be the elasticity of a monopolistically competitive seller's demand curve.

Product Differentiation

A marketing strategy that businesses use to distinguish their product from similar offerings in the market, through variations in quality, features, style, or branding.

Monopolistically Competitive

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

Elasticity

A measure of how much the quantity demanded or supplied of a good responds to a change in one of its determinants, such as price.
