Abstract
This study investigates the effects of brand equity on customer satisfaction after
service failures. We posit that the effects of brand equity are contingent upon the attributions
customers make about the firm’s controllability over a service failure. Two competing
hypotheses are examined and reconciled. The “love is blind” hypothesis posits that when low
controllability is inferred, the satisfaction reduction after a service failure (compared to
satisfaction before a service failure) will be smaller for high-equity brand than for low-equity
brand. On the other hand, the “love becomes hate” hypothesis specifies that when high
controllability is inferred, the satisfaction reduction after a service failure will be stronger for
high-equity brand than for low-equity brand. The hypotheses are tested with a scenario
methodology and this study conducted research in two service industries: hair salons and
restaurants.

Chapter 1 Introduction 1.1 Research Background
No one in the service industry can entirely escape failure (Fisk, Brown, & Bitner, 1993).
Although service firms try to offer a high level of quality in their activities, they are unlikely
to be able to eliminate all service failures (Miller et al. 2000; Lewis & Spyrakopoulos, 2001).
The very personal and intangible characteristics of service delivery frequently produces
situations in which customer needs are misjudged or mishandled, resulting in customer
dissatisfaction. Even well-respected and highly esteemed brands sometimes fail their
customers. Most of us have had the experience of purchasing a venerable brand, but
eventually finding that after-sales service is quite disappointing. When a failed brand
possesses high a priori equity, how customers react is a very important issue. We need to
examine the relationship between brand equity and consumer response to service failure.
Branding theory suggests that the benefit of positive associations enjoyed by a
high-equity brands predisposes favorable responses to it (Keller, 1998). Previous research has
stressed that high-equity brands are more profitable because customers shop more regularly,
spend more per visit (Wulf, Odekerken-Schroder, & Iacobucci, 2001) and are willing to pay a
premium on the products and services they buy (Dowling & Uncles, 1997). Brand equity
represents a key asset for service firms, but it also is at risk of a failed service experience.
of a high-equity brand. First, according to the disconfirmation paradigm (Richard L. Oliver,
1981), customers’ expectations serve as a salient reference point when evaluating the current
consumption experience. Therefore, as frustration is compounded by the high expectations
attached to brands of strong stature, consumers’ adverse reactions may escalate. Second, other
researchers have found that high brand equity provides an important buffer to service firms
when service failures occur, resulting in less dissatisfaction (Goodman, Fichman, Lerch, &
Snyder, 1995; Hess Jr, Ganesan, & Klein, 2003; Kelley & Davis, 1994).
Therefore, it is imperative that managers should carefully consider what conditions
might “soften the blow”, or may mitigate customers’ negative responses toward the failure of
a high-equity brand. This issue is at the center of this research.
1.2 Research Motivation
Service failures are the leading cause of customer switching behaviors (Keaveney, 1995).
For decades researchers have studied branding theory and service failures. Understanding
how brand equity affects customer responses to service failure is important because service
failures have the potential to switch loyal customers to “enemies”. The consequences are very
serious for a firm’s reputation and long-term profitability. Therefore, we focus on the effects
of brand equity upon customers’ negative emotions and satisfaction after service failures.
In addition, integrating the contributions of brand equity and the investigation into
about the causes of service failures (causal attributions) moderate the relationship between
brand equity and satisfaction. This is an issue that has not been sufficiently studied to date.
Finally, this study offers a framework that reconciles these two competing explanations:
the “love is blind” versus the “love becomes hate” effects.
1.3 Research Objectives
In view of the above, the research aims to find:
1. The differences of customer responses to service failures by high-equity brands and
low-equity brands.
2. Whether the role of causal attributions (controllability) would moderate the effect of

Chapter 2 Literature Review
This research posits that the effects of brand equity on customers’ responses depend on
the attributions customers make about a firm’s control over failures.
First, we need to know that when services or products fail, people tend to engage in
causal attributions (Weiner, 2000). Typically, causal attributions can result in three types of
blame: customers think it was the service firm's fault, they don't know exactly who to blame,
or they become aware that they are partly to blame (Laufer, David, & Mayer, 2005). If the
failure is perceived to be partly attributable to the customer, or if the service firm's ability to
control the failure is ambiguous, the negative effect is lessened. Conversely, if the firm is seen
as having had control over the failure but did not prevent it, then customer reactions are
highly negative (Sunmee C & Mattila, 2006). Attributions about controllability are important
in this research because they are thought to increase the customers’ negative emotions and
dissatisfaction toward a firm after service failures (Folkes, 1988).
2.1. Brand equity
After the term “Brand Equity” appeared in the 1980s, it became more and more popular
in marketing theory and practice. Aaker (1991) noted that brand equity is a set of brand assets
and liabilities linked to a brand, its name and symbol, which add to or subtract from the value
provided by a product or service to a firm and to that firm’s customers.
brand equity, including brand associations, brand awareness, perceived quality and loyalty
(Aaker, 1991). The concept of brand equity is shown in Figure 2.
Figure 2 Composition of Brand Equity
Zeithaml (1988) defines perceived quality as “the consumer’s judgment about a
product’s overall excellence or superiority”. High perceived quality means that, through the
long-term experience related to a brand, consumers recognize the differentiation and
superiority of the brand. They are confident that a brand is dependable and can be relied on to
serve them well. Therefore, high perceived quality would drive a consumer to choose a
particular brand rather than other, competing brands.
Brand loyalty makes consumers purchase a brand routinely and resist switching to
another brand. Loyal consumers show more favorable responses to a brand than non-loyal or
switching consumers do. They love to maintain their relationship with a firm.
Brand awareness can provide familiarity with a brand and a signal of substantiality and Brand Equity Asset Customer Consciousness Customer Action Brand Associations Brand Awareness Perceived Quality Brand Loyalty Other Proprietary Brand Assets
promise. If customers know the brand, they usually select familiar products when making
purchase decision.
Brand associations are complicated and connected to one another, and consist of multiple
ideas, episodes, instances and facts that establish a solid ground of brand knowledge. Brand
association can assist a customer to deal with or memorize information. The information
becomes the basis of product differentiation and product extension, and which will provide a
purchasing reason for customers, and give rise to positive feeling.
According to the literature, brand equity is a multidimensional concept. The appraisal of
brand equity can be assessed from the viewpoint of the manufacturer, distributor or customer.
This study focus on a “customer-based” conceptualization of brand equity to characterize
high-equity brands as those for which consumers have substantial knowledge structures that
often include associations that are both readily accessible and positive in valence (Aaker,
1991, 1996; Keller, 1993, 1998). By these criteria, Disney would constitute an example of a
brand with strong equity for many consumers, because favorable associations may be
available in long-term memory as a result of personal experience or exposure to heavy
advertising campaigns and other communications about the very prominent Disney brand.
Branding theory suggests that a cache of positive associations enjoyed by a high-equity brand
predisposes favorable responses to it (Keller, 1998).
access relatively few positive associations, may experience comparatively little change in the
wake of a performance failure. Knowing fairly little about a brand prior to interaction with it,
may suggest little in the way of performance expectations that could be mismatched by a
failure. Disappointment may thus be comparatively minimal, and evaluations of the brand
may change only negligibly as a result of the failed engagement.
2.2 Two rival explanations: “Love is blind” versus “Love becomes hate”
When customers are confronted with service failures of high-equity brands, two rival
explanations exist for the effects of brand equity on customers’ responses: the “love is blind”
versus the “love becomes hate” effect.
2.2.1 Love is blind
The “love is blind” effect argues that customers are more reluctant to hurt a valued
service partner or to terminate a meaningful relationship with high-equity brand (Lind & Tyler,
1988). These customers are more likely to forgive a service failure of a high-equity brand.
Hence, when the failed brand is a high-equity brand, the reduction of consumer satisfaction
will be smaller compared to that for a low-equity brand. It suggests that high-equity brands
provide an important buffer to service firms when service failures occur (Goodman et al.,
1995; Hess Jr et al., 2003; Kelley & Davis, 1994). This effect finds support in the literature on
assimilation bias (Herr, Sherman, & Fazio, 1983) and interpretation bias (Ahluwalia, 2000).
performance will be minimized or assimilated by the consumer adjusting his/her perception of
the product so as to be more consistent with the expectations. In an ambiguous situation, an
assimilation bias leads customers to overlook or underweigh information that is inconsistent
with their positive priors because of their strong connection and trust with the firm.
Consequently, customers of high-equity brands are less likely to feel unhappy by a service
failure. In order to maintain consistency between their positive priors and the current
perceptions of being involved in a service failure, customers may reduce the weight and the
spillover effects of the inconvenience occurred by high-equity brand. Because of these
cognitive biases, they are more likely to forgive a service failure by a high-equity brand.
In addition, customers of high-equity brands may feel reluctant to hurt a valued exchange
partner with whom they feel connected and whom they trust. For those customers, the
connections with high-equity brands are so important that they become reluctant to hurt the
firm because, by doing so, they create negative reflection of their self-esteem and how they
define themselves (Bhattacharya, Rao, & Glynn, 1995).
2.2.2 Love becomes hate
The “love becomes hate” effect posits that a high-equity brand’s favorable associations
lead customers to expect strong utilitarian benefits (Chandon, Wansink, & Laurent, 2000). A
failure by such a brand may engender particularly keen disappointment. When this occurs, a
performance disruption. This, in turn, may tarnish the consumer’s view of the formerly
admired brand. As such, a service failure by a high-equity brand represents a sharper contrast
with the customers’ expectations, and as result customers see a service failure as an act of
betrayal and result in more negative satisfactions and emotions (Robinson, 1996).
In this study, this explanation suggests that customers experience more dissatisfaction
from high-equity brand than low-equity brand in service failure contexts. This effect finds
support in the literatures on contrast effect (Herr et al., 1983). When expectations are not
matched by actual product performance, contrast theory suggests that the surprise effect or
contrast between expectations and outcome will cause the consumer to exaggerate the
difference between the what the product delivered and what was expected from the product,
i.e., if the objective performance of the product fails to meet a customer’s expectations, the
customer will evaluate the product less favorably than if he/she had no prior expectations of it.
Contrast is thus the opposite of assimilation. Since a high-equity brand’s favorable
associations lead customers to expect strong benefits, customers have higher expectations
about high-equity brand service than they believe they deserve. Being involved in a service
failure sharply contrasts with their expectations, and may result in more negative responses
(Brockner, Tyler, & Cooper-Schneider, 1992). A similar contrast effect has been observed in
the information processing literature, when individuals face extreme examples that conflict
In addition, customers of high-equity brands are more likely to feel betrayed than
customers of low-equity brands after service failure. Because of high-equity brand, customers
have more confidence in a firm, a service failure may generate feelings of broken trust and
will therefore be viewed as an act of betrayal (Robinson, 1996). A feeling of betrayal will lead
customers to be even more dissatisfied.
2.3 Firm’s controllability over failure
When services or products fail, people tend to engage in causal attribution (Weiner,
2000). Causal attribution theory suggests that consumers make inferences about the causes of
failure in the delivery of services (Heider 1958). These inferences have three dimensions
(Weiner 1985, 1986): locus of causality, stability and control. Locus of causality refers to
whether the consumer believes the cause of the service failure is related to the firm or to the
consumer. Stability is the extent to which a cause is viewed as temporary (expected to vary
over time), or predictable and permanent (expected to persist over time). Control attribution
involves the consumers’ belief about whether the firm could prevent a failure from occurring,
or alternatively it is the situation that forces the firm to follow a certain course of action.
Heider (1958) argued that consumers often use consistency principles to form attributions. An
excellent service organization should have less tolerance for stable failures. Thus, consumers
who have experienced excellent quality past service performance are less likely to make
less likely to attribute failures to stable causes, and they can be very beneficial for a firm
(Hess et al. 2003; Bagozzi et al. 2002). In this study the focus is restricted to control
attributions because they are thought to affect customer satisfaction toward a firm after
service failures (Folkes, 1984).
Control attribution deals with the perception that the firm could have controlled the
outcome (Hui, Tse, & Zhou, 2006; Weiner, 1985, 2000). If a failure is seen to be partly
attributable to a customer, or if a service firm's controllability over the failure is ambiguous,
the negative effect is lessened. Conversely, if a firm is seen as having had control over a
failure but did not prevent it, then customer reactions tend to be highly negative (Sunmee C &
Mattila, 2006). Formally, the attributions of a firm’s controlling ability are defined as
customer assessment of the degree to which the firm had control over a service failure and can
be blamed for its occurrence (Folkes, 1984).
The greater the perception of past service quality, the more likely consumers will
attribute high levels of competence and effort to avoid service failures to the service
organization (Narayandas 1998). As Hess et al. (2003) find, when a service failure occurs in
the context of high-quality past service performance, consumers are likely to infer that the
organization is highly competent and had little control over the failure, which would
2.4 Negative emotions
The literature on consumer behavior (Folkes 1988; Oliver & DeSarbo 1988; Spreng et al.
1996; Oliver 1997) suggests that individuals’ emotional responses to a service failure are
influenced by their causal explanation for the failure and that causal attributions about the
problem imply negative affective reactions. Specifically, it is argued that consumers express
more negative emotions (e.g. anger) after a service failure when the firm has control over the
problem.
This attribution–emotion relationship is also consistent with Bagozzi et al. (1999)
contribution from Cognitive Appraisal Theory. These authors point out that “emotions arise in
response to appraisals one makes for something of relevance to one’s wellbeing” (p. 185). In other words, it is not the service failure that creates the emotions, but rather the evaluations
that individuals make about the causes of the problems in the service. Additionally, several
empirical studies from other research areas, such as customer satisfaction (Mattila & Wirtz
2000; Oliver et al. 1997) and perceived justice with service recovery (Schoefer & Ennew
2005; Chebat & Slusarczyk 2005), provide support for the argument that cognitive elements
explain individuals’ emotions.
Therefore, the sequence of events after a service failure would be as follows: first the
customer makes attributions about the control of the causes of the service failure; then, the
subsequently will have a negative effect on satisfaction. In this study, customer negative
emotions are the first dependent variable.
2.5 Satisfaction Reduction
Consumer satisfaction has been discussed for several decades since Cardozo (1965) first
brought it up, and has various definitions in the literature. From a consumer’s perspective,
satisfaction represents a pleasurable consumption experience. It can influence a consumer’s
attitude towards a product and his intention to repurchase (R. L. Oliver, 1980). From a firm’s
perspective, satisfaction considerably contributes to the increase of its profitability. Research
has supported the existence of a positive relationship between customer satisfaction and
financial performance (Anderson, Fornell, 1997).
Customer satisfaction could be characterized as an evaluative judgment, with an
evaluation being made between expectation and product or service performance, after a
purchase has been completed (R. L. Oliver, 1980). Expectancy-disconfirmation theory is one
of the most influential topics in customer satisfaction studies (Zwick, Pieters, & Baumgartner,
1995), and in which consumer satisfaction can be specified as a function of initial standard
judgment which is compared to the level of perceived performance (Westbrook & Oliver,
1991). Consumers are assumed to assess a product before actually purchasing it. If
performance exceeds expectation, a positive disconfirmation will be expected and people will
disconfirmation when performance does not meet their expectations (Zwick et al., 1995).
Cognitive dissonance theory suggests that individuals will adopt a dissonance reduction
strategy if they experience disconfirmation consumption (Tse & Wilton, 1988). People may
distort their cognition of how the service is performed and assimilate their judgments into
their initial expectations if they don’t want to admit the difference between expected and
actual experience (Anderson, 1973). When consumers experience dissonance after
consumption, they will align their assessments with their expectations.
Maxham & Netemeyer (2002) examined overall firm satisfaction as a customer’s
cumulative satisfaction after multiple experiences, transactions and encounters with a service
organization (Maxham & Netemeyer, 2002; Smith & Bolton, 1998). Since some customers
may view a service failure as a single specific experience which may result in slight
differences in overall firm satisfaction, this study examines two kinds of satisfaction
constructs: overall satisfaction before a service failure, and satisfaction after service failure.
The difference between the satisfaction based on the past experience and the consumer
satisfaction after service failure as satisfaction reduction is used, to see the effect of a single
service failure. This is the dependent variable in this study.
2.6 Patronage Reduction
Satisfaction literature strongly supports the idea that increased satisfaction with a service
same service provider (Harris, Grewal, Mohr, & Bernhardt, 2006). After service failure,
customers dissatisfaction and negative emotions should influence customers’ intentions and
behavior (Fishbein & Ajzen, 1975; Perugini & Bagozzi, 2001), such as the intent to
repurchase from the firm.
In this section, we examine complaint behavior examined in service failure literature
(Singh, 1988). i.e. patronage reduction. Customers can remove the benefits that their future
patronage would have generated. More specifically, patronage reduction is defined as a
customer’s efforts to reduce the frequency of his or her visits, spend less per visit, and to
frequent competitors more intensively (Wulf et al., 2001). Customer could decide to avoid a
firm because he or she does not want to repeat a negative experience.
2.7 Hypotheses
In this research, it is hypothesized that the “love is blind” versus the “love becomes hate”
effects are contingent upon the attributions made by customers about a firm’s ability to
control the service failure. Controllability attributions reflect the customers' beliefs that the
service firm could have prevented the failure (Folkes, 1984; Hamilton, 1980; Hess Jr et al.,
2003; Weiner, 2000). Attributions about a firm’s controllability are defined as customers’
judgments of the degree to which the firm had control over a service failure and can be
blamed for its occurrence (Folkes, 1984).
effect explains the influence of brand equity on customer responses to service failures.
Consistent with the logic supporting this effect, customers of high-equity brands, compared to
low-equity brands, experience smaller satisfaction reductions for two reasons. First, their
perceptions of high-equity brands bias the way they assimilate and interpret information
related to the service failure. For high-equity brands, customers overlook or reduce the effect
of the inconvenience associated with an uncontrollable service failure. Second, dissatisfaction
and negative images seem contrary to maintaining a strong and positive psychological
connection, especially when the service failure is beyond the control of the firm. In this
context, customers of high-equity brands experienced smaller satisfaction reductions for a
firm they trust and with which they strongly identify. In addition, when customers believe that
the firm did not have the ability to do anything, or when external forces caused the failure
(Folkes et al., 1987), their negative emotions are less intense (Folkes, 1984). Last, patronage
reduction is defined as a customer’s efforts to reduce the frequency of his or her visits, spend
less per visit, and to frequent competitors more intensively (Wulf et al., 2001). However,
when attributions of low controllability are made, customers of high-equity brand may feel
reluctant to hurt a valued exchange partner to whom they feel connected and in whom they
trusted. Then:
Hypothesis 1a: When customers attribute a service failure to a low controllable
than toward low-equity brands (i.e., “love is blind” effect).
Hypothesis 1b: When customers attribute a service failure to a low controllable
cause, their satisfaction reductions after a service failure (compared to satisfaction before a service failure) will be smaller for high-equity brands than for low-equity brands (i.e., “love is blind” effect).
Hypothesis 1c: When customers attribute a service failure to a low controllable
cause, their patronage reductions will be significantly smaller for high-equity brands than for low-equity brands (i.e., “love is blind” effect).
On the other hand, when customers infer that a firm had control over the service failure;
the “love becomes hate” effect explains the effect of service failures by high-equity brands.
Compared to low-equity brands, customers of high-equity brands experience greater
satisfaction reduction for two reasons. First, customers of high-equity brands have higher
expectations about the service they believe they deserve, and therefore a controllable service
failure more sharply contrasts with their expectations. In addition, they are more likely to feel
betrayed by the actions of a high-equity brand than low-equity brand (Robinson, 1996). Also,
controllable service failures are likely to be viewed as grounds for anger because a deliberate
act is a more significant breach of trust for customers who have a strong belief in and
connections with the firm. When customers believe that the firm had the ability to do but
Formally:
Hypothesis 2a: When customers attribute a service failure to a high controllable
cause, their negative emotions toward high-equity brands will be significantly stronger than toward low-equity brands (i.e., “love becomes hate” effect).
Hypothesis 2b: When customers attribute a service failure to a high controllable
cause, their satisfaction reductions after a service failure (compared to satisfaction before a service failure) will be greater for high-equity brands than for low-equity brands (i.e., “love becomes hate” effect).
Hypothesis 2c: When customers attribute a service failure to a high controllable
cause, their patronage reductions will be significantly greater for high-equity brands than for low-equity brands (i.e., “love becomes hate” effect).
2.8 Research Framework
The major focuses of this study is to identify (1) the contingency effect of a firm’s
controllability and (2) the interaction between brand equity and firm’s controllability. The
Figure 3 Research Framework (1)
Depending on the attributions made about a firm’s controllability, this study posits that
customers experience a smaller or a greater reduction of satisfaction of high-equity brands
than do customers of low-equity brands. The two components of hypothesis 1 and 2 are
represented in Figure 4.

Chapter 3 Methodology 3.1 Conceptual Research Framework
3.2 Experimental Design
This study set out to determine how the attributions customers make about a firm’s
control over failures influences the effects of brand equity on customers’ responses, when they
are confronted with service failures. To increase generalizability, this study conducted
research in two service industries: hair salons and restaurants. Hair salons and restaurants
were ideal for the study because both are commonly used by and familiar to a wide range of
consumers, which should provide a diverse group of respondents who could meaningfully
complete the survey. In addition, both service industries maintain a strong presence in
high-equity brand contexts
Testing the model in these two services therefore should have implications for existing
theories and for managers of high-equity brands.
3.2.1 Experiment Procedure
This study constructed scenarios to manipulate the brand equity and firm’s controllability
over service failure across the two service industries with a completely randomized full
factorial design. The participants were randomly assigned to one of the four cells in a 2 × 2
(firm’s controllability over the failure: low or high × brand equity: high versus low)
Table 1 Experimental design
Firm’s Controllability Over the Failure
Brand Equity Low High Low
High
Low: partial blame to other customers or who to blame is unknown;
High: the firm is perceived to have had the ability to prevent the failure but did not.
Written scenarios were used to create the four experimental conditions in the two service
industries. A scenario methodology was chosen for the study, in which subjects were asked to
imagine themselves in the scenarios presented. Scenario methodology has been used in
previous studies of customer reaction to service failure. There is strong evidence that
individuals respond to an experimental scenario in the same manner as they would respond to
a similar, actual experience (Maxham & III, 2001).
Initially, respondents learned that they would participate in one study about the service
experiences. In the scenarios, participants were asked to recall an actual hair salon (restaurant)
where they received service before. In both service industries, participants were randomly
assigned to two brand equity conditions, to complete the brand equity scales and the customer
satisfaction scales depending on the quality of past experiences.
Respondents first read a short description of a firm. In the case of the hair salons,
respondents were told to imagine that they had already made an appointment to get their hair
cut. However, when they arrived on time, the respondents find out that they have to wait for
In the restaurant scenario, respondents were asked to imagine that they had already made
an appointment for dinner. Then the respondents subsequently learn that they have to wait for
35 minutes to become seated. Next, both groups of respondents read scenarios describing one
of two controllability manipulations. Last, respondents were asked to complete the customers’
satisfaction scales again after service failure in order to examine the intensity of their negative
emotions, and the degree of satisfaction reductions was analyzed. In addition, patronage
reduction was used to exam the customers’ response after service.
3.2.2 Stimulus Development
Manipulation of brand equity
To manipulate brand equity, the study selected some pictures for different brand equities.
There were three exclusive and luxurious hair salon pictures for a high-equity brand
manipulation and three pictures of university-affiliated haircut service for a low-equity brand
(Appendix A). In addition, this study provided a description about the service and the quality
of the hair salon corresponding to the pictures in order to induce customers to recall one hair
salon that he/she has been to (Appendix A). In this study, we used perceived quality, which is
one dimension of brand equity to do the manipulation check since it is the most obvious and
external concept to evaluate brand equity. Therefore, consistent with well-established
measures of brand equity (e.g., Aaker and Keller 1990; Smith and Park 1992), we considered
quality reflects a global brand evaluation (DelVecchio, Jarvis, Klink, & Dineen, 2007). For
the purpose of a manipulation check, participants were asked to report the name of the hair
salon he chooses and to complete the brand equity scale adapted from Yoo & Donthu (2001).
Examples included, “The likely quality of this hair salon is extremely high.” and “This hair
salon’s quality appears to be reliable.” (1 = “strongly disagree,” 7 = “strongly agree”). Results
supported the high- and low-equity brands’ intuitive designations. In addition, the pictures and
description that represents high equity was rated significantly higher on the brand-equity scale
than the low-equity hair salon brand. The results of the manipulation will be reported in
Chapter 4.
Manipulation of a firm’s controllability over failure
A service failure scenario was designed to stimulate participaants into an unsatisfactory
service experience due to an unnecessarily long wait. The respondents were randomly
assigned to two scenarios about the firm’s controllability over failure.
To manipulate the controllability variable, we depicted in two scenarios. Both scenarios
were that customers had to wait 35 minutes for their hair cuts even if they had already made
an appointment three days previously (occurrence of service failure). However, in a firm’s
high controllability over failure situation, the reason for making the customers wait was that
the salon forgot to make the appointment. In a low controllability scenario, failure happened
firm’s controllability over failure depends on how the participants attribute the service failure.
This study used the scale of attributions about the firm’s controllability developed by
Maxham and Netemeyer (2002). (e.g. “The service failure was entirely the organization’s
fault.”, on a scale from 1 = strongly disagree, to 7 = strongly agree)
3.3 Measurements
3.3.1 Brand Equity
The Scale of Brand equity adapted from Yoo & Donthu (2001) was used to check the
effect of the brand equity manipulation. It measures perceived quality of high- and low-equity
hair salon brands. The 7-point Likert scale was chosen. Seven points represents “strongly
agree”, and one point represents “strongly disagree.
Scale Items:
1. The likely service quality of this hair salon is extremely high. 2. The skill of hair stylist in this hair salon is extremely high. 3. The quality of this hair salon appears to be reliable.
3.3.2 Negative emotions
Respondents assessed the degree to which they would feel anger, shock, irritation
(Richins, 1997), regret, and betrayal. This scale has a reliability alpha of 0.883.
Scale Items:
1. I would feel very angry. 2. I would feel regret. 3. I would feel betrayed. 4. I would feel shocked. 5. I would feel irritated.
3.3.3 Satisfaction
The 7-points Likert scale was chosen. Seven points represents “strongly agree”, and one
point represents “strongly disagree. Following prior research we modified the words to fit this
study, and measured customer satisfaction after the service recovery on a three-item scale
(adapted from Maxham Ⅲ & Netemeyer (2002).
Scale Items:
1. On the whole, I am/was very satisfied with my experience with this/that service. 2. In general, I am/was happy with the service experience.
3. Overall, my positive experience outweighs/outweighed my negative experience with this/that service.
3.3.4 Patronage Reduction
Patronage Reduction was measured by a four-item, seven-point scale which was
used by Wulf et al.(2001).
Scale Items:
1. I spent less money at this business. 2. I stopped doing business with this firm.
3. I reduced frequency of interaction with the firm. 4. I took a significant part of my business to a competitor.
3.3.5 Firm’s Controllability Over Failure
Attributions about the firm’s controllability were measured with a three-item scale
developed by Maxham and Netemeyer (2002). This scale was based on semantic differential
items.
Scale Items:
1. This hair salon was entirely responsible for the problem that I experienced. 2. The problem that I encountered was solely this hair salon's fault.
3.4 Data Collection and Analysis Methods
First, an Independent-Sample T Test was employed to determine if brand equity (high vs.
low) and firm’s controllability over failure have significant differences under stimulus
manipulation. Then, ANOVA was used to determine the firm’s controllability over failure on
the effect of brand equity on the decline of satisfaction, and thus understand the influence of
moderator.
3.5 Pretest
A pilot study was conducted to test the validity and reliability of the questionnaire.
Researchers use this method to discover problems or misunderstandings in the design of the
experiment and then modify it before the official study. After our questionnaires failed and
were modified four times, the fifth edition of pilot study was successful.
The pretest was made by giving forty participants the experimental questionnaires,
telling them the research purpose was concerned with consumer behavior. There were twenty
male and twenty female participants. Twenty-two of the forty participants were students. The
reliability of customer satisfaction scales was 0.891, the reliability of the negative emotions
scales was 0.968, and the reliability of the patronage reduction scales was 0.924. All
reliabilities of scales were higher than 0.7. In addition, there was significant difference
between high-equity brand and low-equity brand (p<0.00). The difference between high and
Chapter 4 Research Analysis and Results
This chapter contains the analysis and the results of this study, including the background
of respondents, manipulation checks, reliability and validity of the results. A 2 (brand equity)
× 2 (firm’s controllability over failure) between-subjects experiment was conducted. Also, this
study conducted research in two service industries (hair salon and restaurant) to determine the
generalizability of our model. The type of service didn’t affect any dependent variables as we
expected. In other words, there was no significant difference between the service types.
However, since the scenarios are different in two service industries, this study discussed the
results separately, which has been used in previous studies of customer reaction to service
failure (DeWitt & Brady, 2003; Gremler & Gwinner, 2000 ). Therefore, this study first gave
the results of haircut scenario and then the results of restaurant scenario. Data analysis
techniques such as ANOVA, multi-comparison, and Independent-Sample T Test were
employed to test the hypotheses. The study used SPSS 12.0 to analyze the data.
4.1 Background of Participants
In the haircut scenario, from the total sample of 145 participants, 55.17% were students,
53.8% were female, 40% were between 21 and 25 years old, 57.93% have college degree,
39.31% have a graduate or higher degree, 35.86% have incomes between NT10,000 to
NT30,000.
51.2% were female, 42.4% were between 21and 25 years old, 61.8% have college degree,
37.1% have a graduate or higher degree, 47.6% have income less than NT10,000. The
demographics of all respondents are listed in Table 2.

4.2 Reliabilities
In both service industries, the reliabilities of all constructs in this research were tested
with Cronbach’s alpha. Table 3 shows that reliabilities are all above 7 across all factors,
which indicate the high internal consistency of each item of the same factor.

In the haircut scenario, there were 73 participants in the high-equity brand and 72 in the
second group, with the low-equity brand. An Independent-Sample T Test was conducted to
investigate the differences of brand equity between the two groups. It is shown that the brand
equity of low-equity brand is significant lower than high-equity brand (t-statisitcs = -8.336, p

difference of brand equity between the two groups. It was shown that the brand equity of low
controllability is significantly lower than for high controllability (t-statisitcs = -6.551, p <

4.4.2 Brand Equity with Firm’s Controllability over failure and Negative Emotions
Hypothesis 1a indicated that when attributions of low controllability are made, customers
will experience weaker negative emotions with high-equity brands than with low-equity
brands. Hypothesis 2a speculated that when attributions of high controllability are made,
customers will experience stronger negative emotions with high-equity brands than with
low-equity brands.
contains the results of ANOVA and shows that a firm’s controllability could significantly
affect customers’ negative emotions (p <0.01). Further, the interaction between brand equity
and a firm’s controllability over failure is given in Table 10 (also see Figure 5). When
attributions of a firm’s low controllability over failure are made, there were significant
differences between high-equity and low-equity brands (p < 0.01); the same results happened
when attributions of a firm’s high controllability are made.
Table 11 shows that after a service failure, when attributions of low firm’s controllability
are made, customers’ negative emotions are significantly weaker with high-equity brands than
with low-equity brands. Hypothesis 1a is supported (p <0.05). It also confirms that when
attributions of a firm’s high controllability are made, customers’ negative emotions are
significantly stronger with high-equity brands than with low-equity brands. Hypothesis 2a
was supported (p <0.05). Both service industries support hypothesis 1a and hypothesis 2a.

Figure 6 Interactions between Brand Equity and Controllability (Restaurant) 4.4.3 Brand Equity with Firm’s Controllability over failure and Satisfaction reduction
This part of the project attempts to establish whether there is an interactive effect
between brand equity and firm’s controllability over failure on the satisfaction reduction.
Hypothesis 1b speculated that when attributions of low controllability are made,
customers will experience smaller satisfaction reductions with high-equity brands than with
low-equity brands (i.e. the “love is blind” effect). Hypothesis 2b showed that when
attributions of high controllability are made, customers will experience greater satisfaction
reductions with high-equity brands than with low-equity brands (i.e. the “love becomes hate”
effect).
Table 15 shows the descriptive statistics of brand equity and controllability. Table 16

shows the results of ANOVA and that firm’s controllability could significantly affect the
reduction of customers’ satisfaction (p <0.01). Table 16 also shows the interaction between
brand equity and firm’s controllability over failure (see Figure 7 also). When attributions of
low controllability are made, there were significant differences in the reduction of satisfaction
between high-equity and low-equity brands (p < 0.01); the same results were obtained when
attributions of high firm’s controllability over failure were made (p < 0.01).
Table 17 shows that after a service failure, when attributions of low firm’s controllability
are made, the reduction of customers’ satisfaction is significantly lower with high-equity
brands than with low-equity brands. Hypothesis 1b was supported (p <0.05). It also confirms
that when attributions of high firm’s controllability over failure are made, the reduction of
customers’ satisfaction is significantly higher with high-equity brands than with low-equity
brands. Hypothesis 2b was supported (p <0.05). Both service industries support hypothesis 1b
and hypothesis 2b.
