Background: The concept of Brand loyalty has been defined in a number of ways by different academics and practitioners. Brand loyalty has been largely defined and measured in either behavioral or attitudinal terms (Mellens et al., 1996). Most researchers agree that loyalty is a very complex construct (Javalgi and Moberg, 1997) and most utilize the composite definition of brand loyalty which was originally proposed by Jacoby (1971). According to Jacoby's concept definition brand loyalty can be defined as:

The biased (non-random) behavioral response (purchase) expressed over time by some decision-making unit with respect to one or more alternative brands out of a set of brands and is a function of psychological processes. Brand loyalty has not, however been uniquely defined and operationlised in the marketing literature. For example, brand loyalty has been defined as a repeat purchase, preference and commitment, and as retention and allegiance. Brand loyalty has also been defined as a special case of programmed decision making when customers adopt a decision strategy of giving all or most of their patronage to a particular brand. '(Runyon 1980p. 355). Lawrence defined loyalty to a new brand as four purchases in a row (Lawrence, 1969,pp.137-144). However Blattberg and Sen used a proportion of purchases rather than a sequence as an indication of loyalty to national and private label brands (Blattberg & Sen, 1976, pp.34-35). Yet to consider a consumers sequence of purchases as an indication of their loyalty towards a brand may be misleading. 'Repeat purchase of the brand may not represent commitment, it may merely represent acceptance of the brand.' (Assael, 1998,p.134). Indeed repeat purchase may also occur in a monopoly situation as well as when little choice is available.

Brand loyalty has been viewed from three different, albeit complementary, perspectives, namely: the behavioral, the attitudinal and the reasoned action perspectives. More specifically the behavioral perspective has conceptualized brand loyalty in terms of repeated purchases (for example, Cunningham and Kahn et al.). In fact several models have been proposed in the literature in order to study brand loyalty from the behavioral perspective, the Dirichlet model being one of the most prominent. These approaches model the consumers' faithful enactment of a promise to consistently purchase only one brand, although they fail to model the reason(s) behind this behavior. One possible insight could be found in the attitudinal perspective in conceptualizing loyalty. According to this perspective, brand loyalty consists of a strong internal disposition towards a brand leading to repeated purchases. As such the attitudinal approach conceives brand loyalty based on stated preferences, commitment, or purchase intentions. Attitudinal and behavioral brand loyalty are positively correlated. The theory of reasoned action states that the consumers behavior may be influenced by social pressures, thus explaining how a consumer's brand attitude may be unfavorable, while the consumer repeats the purchases of a particular brand. In such a case the consumer's brand loyalty would be superficial. According to the reasoned action paradigm - based on the theory of reasoned action, introduced by Fishbein - brand loyalty is conceived as a notion that is dependent on normative influences (such as influences deriving from social peers). These influences, in turn, are reflected in the behavioral consequences of loyalty. According to this view, one may hold a favorable attitude towards a brand but still not purchase it because of not being able to afford it, a partner disliking the brand, or for many other reasons. Such an individual, although having never actually purchased the brand, promotes it in public, recommends it, and compels others to buy it. This situation is similar to the theoretical discussion by Oliver of the loyalty phrases, and particularly the cognitive phase, where loyalty is based merely on 'brand benefit' and not on brand experience.

The importance of brand loyalty has been recognized in the marketing literature for at least three decades (Howard and Sheth 1969, p.232). Brand loyalty is infact a part of the Basic model of the consumer behavior. Aaker (1991) has discussed the role of loyalty in the brand equity process and has specifically noted that brand loyalty leads to certain marketing advantages such as:

* Reduced marketing costs

* More new customers

* Greater trade leverage

In addition, Dick and Basu (1994) suggest other loyalty-related marketing advantages, such as:

* Favorable word of mouth

* Greater resistance among loyal customers to competitive strategies

Brand loyalty gives sellers some protection from competition and greater control in planning their marketing programs.' (Kotler, 1994,p.448). A significant proportion of the consumer preference choices can also be explained by brand loyalty. It has been researched that recruiting a new customer can be five times more costly than selling to an existing one. A base of loyal customers will be advantageous for an organization as loyalty can be capitalized on through strategies such as brand extension and market penetration. Finally a large number of loyal customers is an asset for a brand, and has been identified as major determinant of brand equity (Dekimpe et al., 1997). While most loyalty research has focused on frequently purchased consumer goods, the loyalty concept is also important for industrial goods (vendor loyalty), services (often referred to as services loyalty in marketing literature) and retail establishments (store loyalty).

A review of the loyalty literature has revealed that the measurement of brand loyalty is different for consumable, durable and services markets. This difference is largely attributable to the difference in market characteristics, namely brand switching, purchase frequency, appropriateness of loyalty types for measurement, share of category, proportion of sole buyers, commitment, intention to purchase, perceived risk, inertia, habit, satisfaction and involvement. The categories of consumables, durables and services are mutually exclusive categories as the market characteristics differ between each market type.

Nature of loyalty: There are many competing opinions about the nature of loyalty. One of the most interesting debates on this topic is that between William Neal , president of SDR inc- a marketing research firm and Randall Brandt, researcher at burke inc. In his June 5, 2000 article in marketing news "When measuring loyalty satisfactorily, don't measure CS" Neal says "Loyalty is a behavior. If I purchase in a product category 10 times in one year, and I purchase the same brand all 10 times, I am 100% loyal. If I purchase the brand only five out of 10 times, I am 50% loyal. It's that simple. It doesn't matter whether I am exhibiting that loyalty because I'm truly dedicated to the brand, or it has some performance characteristic that I want or need, or whether I don't have a choice in the matter. I exhibit behavioral loyalty. And that is the point-loyalty is a behavior." Literature reviews suggest that 3 attitudinal and behavioral elements can measure loyalty: product satisfaction, recommendation intention and repurchase intention. Neal suggests all three may measure satisfaction. Pointing to their intercorrelation, he says they "usually are measuring the same thing-- satisfaction with the product or service." This implies a reflective measurement model shown in Figure 1 where all three items "reflect" (arrows pointing outward) a single underlying latent construct: customer satisfaction. "

Neal goes on to say that satisfaction may not always result in loyalty. He says "Value drives loyalty, not satisfaction. Satisfaction is a necessary but not sufficient component of loyalty. If I am not satisfied with my experience with a brand, I won't consider that brand again unless I don't have a choice in the matter. However, just because I am highly satisfied with a brand's performance doesn't mean I will necessarily repurchase that brand at the next opportunity. It simply means it will probably be in my consideration set. I will evaluate the brands in my consideration ...
