The assertion that a better value proposition reduces marketing effort is:

A better value proposition is indeed associated with a reduction in the required marketing effort. This stems from the premise that a strong value proposition clearly articulates the unique benefits and advantages a product or service offers to its target audience. When consumers easily understand how a product meets their needs or solves their problems, they are more likely to be inclined to purchase without requiring extensive persuasion.

This effectiveness contributes to more efficient marketing strategies, as the brand can rely more on the inherent appeal of its value proposition rather than investing heavily in aggressive promotional tactics. Essentially, a well-defined and compelling value proposition can lead to organic word-of-mouth referrals, enhance customer loyalty, and create a competitive advantage, all of which can significantly reduce the need for additional marketing resources and efforts.
