Which of the following statements about the importance of each competitive factor $($but especially such highly influential factors as selling prices, S$/$Q ratings, and number of models$/$styles offered$)$ in determining company sales volumes and market shares in a particular geographic region is false?

In the rare instance that all companies should happen to charge the same wholesale price to retailers in a region and the same online retail price at their websites, then price becomes a total competitive nonfactor and has zero impact on buyer appeal for one company's brand versus another.

Tiny cross$-$company differences on a highly influential competitive factor $($like selling prices, or S$/$Q ratings or models$/$styles$)$ nearly always have a bigger impact on company sales$/$market shares in a region than do large differences on less influential competitive factors like mail$-$in rebates or expenditures for retailer support.

How much company selling prices matter in determining each company's unit sales$/$market share in a region is not a fixed amount but rather is an amount that varies from "big" $($when price differences are also "big"$)$ to "small" $($when prices differences are "small"$)$ to "zero" $($when the prices of rivals are identical$).$

Big company$-$to$-$company price differences in a region weigh heavily in accounting for company$-$to$-$company differences in branded pairs sold and market share in all four geographic regions.

As the spread between the highest$-$priced company and the lowest$-$priced company becomes smaller and smaller, the weaker is the unit sales$/$market share impact of the price differences among competing companies.
