Brand equity is the value consumers associate with the brand name itself, rather than the specific product or service. Put in layman's terms, would you rather wear a plain white T-shirt or the same T-shirt with a Nike logo on it? You'd probably agree that most people would prefer the Nike T-shirt. And they'd be willing to pay more for it.

There are two good reasons why marketers want to increase equity in their brands: (1) better bottom-line results, and (2) greater customer loyalty.

But to increase equity, you must first be able to measure it. And most measurement approaches are complicated and involve complex models.

BRX has an easier way

BRX founder Dr. Joel Axelrod developed Brand Equity Systems to accurately measure brand equity. It's a proprietary system that's not only simple to understand and use . . . but also helps marketers know what they can do to increase brand equity.

Brand Equity SystemsSM uses an operational definition of brand equity that relates the value of a brand to the bottom line (or really, the consumer's wallet):

Brand equity is measured by gauging demand for a product in relation to competitive products. We're really seeking to understand price sensitivity for a product — and judging how much product demand may decrease as price increases. A brand with strong equity will continue to be in demand even as its price increases.

To demonstrate how this system works, we'll look at three studies:

  • A college looking to measure the impact of increased tuition on application rates
  • A manufacturer of a new storage shed who wanted to find out what price consumers would pay for its product
  • An international tire manufacturer wanting to measure the effects of advertising

As part of its Brand Equity Systems,SM BRX has devised an ingenious method for eliciting a truer picture of respondents' price sensitivity and purchase preference among a range of brands, including the "Test Brands" in question.

This is important because respondents often give rational and expected responses because they understand "the game" and these rational answers often encourage marketers to keep the price low. However, they often don't behave rationally. So the challenge, when conducting this type of research, is to not let respondents know that price sensitivity is what's being measured.

Variations on a demand curve

By averaging the purchase preference points for the Test Brand at different price levels, a demand curve can be determined. Typically, we find variations of three different demand curves:

  • Price sensitive
  • Price insensitive
  • Premium quality

The following charts show how price-sensitivity measurement typically works:

Table 1 illustrates a typical price-sensitive curve, where demand increases as price decreases.


Price sensitivity information provides the basis for calculating brand equity. Our basic assumption is that the more resistant the consumer is to price increases, the greater the brand equity.


How much is a good education worth?

Earlier this year, Time magazine ranked Geneseo as one of the 10 best college bargains nationwide, based on the caliber of its students and its above-average graduation rates. With this kind of endorsement, it's hard not to wonder how much a student would pay for an education at SUNY Geneseo. How high could it go without affecting admission application rates?


In Table 2, the price-insensitive curve shows demand holds steady as price increases. This is a definite sign of brand equity.

Our research measurement shows that the number of admission applicants remained stable even as tuition increased. Even though Geneseo has no plans to increase tuition, it can now use this valuable information as a student recruitment tool to tout its educational superiority at rock-bottom tuition prices.

Pricing a new product does not have to be like throwing a dart in the dark

All manufacturers face the challenge of pricing a new product. They know what it costs to make it, but what will a consumer be willing to pay for it?

A manufacturer of Premium Storage Sheds brought this very challenge to BRX. The manufacturer believed they had a new product that the marketplace would readily embrace. And they knew what they wanted to charge for it. The challenge was to see if the two were compatible.


The first part of the study focused on whether the public really wanted the product. The second part was designed to find out if the public would pay the price the manufacturer wanted to charge.

The results are illustrated in Table 3. They clearly show that demand can actually increase as price goes up. Presumably, that's because of quality concerns. The curve also shows the point where the product is no longer viewed as a good value, and subsequently demand starts to drop off.

Our study definitely proved there was market appeal for the new product and the manufacturer had set the right price.

The final result: The Storage Sheds entered the market at a price that's appealing to consumers and that the company can deliver with maximum profitability.

We all ask the question, "What impact does my advertising really have?"

Up to this point, we've described how Brand Equity SystemsSM measures equity. Another application of the system is to provide answers to marketing questions, such as:

"What specific product attribute has the most value to customers?"

"Will sales increase if we lower prices?" (They may not!)

"If we raise our price and lose some customers, which brands will they switch to — another of our brands or a competitor's?"

Brand equity is a strategic goal. It's the very reason companies spend billions of dollars every year on advertising. Imagine being able to really measure the impact of your advertising — and not just by looking at market share.

An international tire manufacturer used Brand Equity SystemsSM to measure their advertising efforts on a quarterly basis.

Using the system as a diagnostic tool, the manufacturer was able to determine which product attributes should be exploited in order to maximize the value of its brand-building advertising efforts. The results also helped define how it should position itself against the competition. But the most important result gained from the system was the knowledge that the marketplace changes — and that means the company's advertising efforts need to change, too.

Here's how the system works:

Brand Equity SystemsSM can be used to determine:

(1) Attribute Importance: the relative importance of product attributes

(2) Attribute Presence: the degree to which competing brands are seen as having the same attributes

Each quarter, participants in the study were asked to rate the relative importance of product attributes when choosing a brand. We know consumers evaluate many product attributes when making purchase decisions, but some attributes carry more weight than others. It's critical to determine which attributes or features are most important.

For example, we asked how much value the manufacturer's brand name carried. Would people pay more for its tires over other brands?

The manufacturer also wanted to focus on the specific product attributes that are most important to customers. While this may seem too tactical, it directly impacts the bottom-line results of advertising efforts. The advertising could zero in on the attributes that consumers felt had the most value. Because the study was quarterly, they could fine-tune as necessary.

Participants were shown several different attributes and asked to distribute a fixed number of points ("constant sum") in a way that indicated their relative importance, as shown in Table 4. For example, is tread wear more important to consumers than traction on wet roads?

Table 4
Attribute Importance
Has long tread life 8
Provides good traction on wet roads 5
Is built with latest technology 2
Gives a smooth ride 3
Has good handling at high speeds 1
Is a good value for the price 6
Stops quickly 5
Total 30

Table 4 is based on Attribute Importance — which specific attributes are most important to customers shopping for tires.

Once the manufacturer understood the relative importance of attributes, the next step was to determine the degree to which each brand was seen as having each attribute. Using a rating scale of 1 to 10 — with 1 meaning "does not describe this brand at all" and 10 meaning "describes this brand perfectly" — the company could see how it compared to the competition as shown in Table 5. Again, this information could have a definite impact on its marketing and advertising plans.

Table 5
Attribute Brand A Brand B Brand C
Has long tread life 4 5 8
Provides good traction on wet roads 6 9 7
Is built with latest technology 6 9 3
Gives a smooth ride 3 5 3
Has good handling at high speeds 7 5 4
Is a good value for the price 5 3 9
Stops quickly 8 9 6

The final results can be directly translated into advertising messages that focus on the consumer's perceived importance of those positive attributes that are seen to outperform the competition. This will build brand equity — and increase sales.

Can Brand Equity SystemsSM work for you?

Today, we're all looking for the "edge" that's going to put our products and services on top. And it's getting more and more difficult as consumers get SMsmarter and competition increases. The solutions aren't black and white. That's why Brand Equity SystemsSM is a valuable and viable tool for measuring the effectiveness of your brand-building efforts.
