Double jeopardy in Kuwait banks: a focus on mutual funds.
Pleshko, Larry P. ; Wugayan, Adel Al-
INTRODUCTION
A company needs to focus at least a proportion of marketing efforts
on the development, maintenance, or enhancement of customer loyalty
(Dick and Basu, 1994). This emphasis is important because a company with
a large number of brand loyal buyers will be more secure in its markets
and should have a higher market share than other firms without this
vital customer asset (Raj, 1985; Robinson, 1979; Smith and Basu, 2002).
Competitors are at a disadvantage when some firms have a larger number
of brand loyal buyers than they have. The many advantages of relatively
higher numbers of brand loyal buyers include: a greater response to
advertising (Raj, 1982), larger purchase quantities per occasion
(Tellis, 1988), and reduced marketing costs (Rosenberg and Czepial,
1983). The advantages garnered from loyalty are especially important
since, as markets become more mature, increases in share become more
expensive and improvements in the loyalty base might be a viable means
of increasing and maintaining share (Gounaris and Stathakopoulos, 2004).
The fact that competitive markets oftentimes exhibit similar market
structure characteristics (market share), which in turn was found to be
correlated with the number of brand loyal buyers, was first noticed by
McPhee (1963). This observance that brands with large market shares
usually had the most brand loyal buyers (and vice versa) was termed
"doublejeopardy" (DJ) because it seemed unfair for smaller
brands to suffer in both ways. Previous research related to DJ suggests
its' applicability to a variety of consumer brands and setting.
Additionally, other consumer-specific variables exhibit a similar
relationship to market share as does consumer loyalty (Ehrenberg et al,
1990).
This study applies the aspects of DJ to the area of mutual fund
services in Kuwait. The setting is relevant because few have
investigated the DJ phenomenon in Asia (Yang et al, 2005). Plus, only
one investigation to this point has studied double jeopardy in the
Kuwait market (Pleshko and Al-Wugayan, 2008). Nor have there been many
studies in the retail services industries. Most research has focused on
brand-level relationships rather than service-level or store-level
relationships, as would be necessary in retailing or banking
(Meyer-Waarden and Benavent, 2006, Rafiq and Fulford, 2005).
Additionally, the DJ topic is extremely relevant to the banking
sector in the Middle East, where markets are opening to global
competition as a result of the Arabian Gulf coast country (GCC) members
joining the WTO. The presence or absence of the DJ phenomenon in
financial services may be critical to companies' decision making,
since it would be difficult for small-share firms to grow and show long
term success with evidence of a strong DJ effect. Additionally, it may
be difficult for foreign or other new firms to enter a geographical
market with strong DJ effects. The authors attempt to identify whether
the DJ phenomenon is evident through a survey of investors in Kuwait by
analyzing the relationship of loyalty to market share as they pertain to
mutual funds.
THE DOUBLE JEOPARDY PHENOMENON
A firm's long-term success depends on both its ability to
attract customers and its capability to retain these customers (McDowell
and Dick, 2001). Jones (1990) points to this fact by stating that
manufacturers should regard sales volume and market share as keys to the
future, given that both involve sources of repeat business and scale
economies. McDowell and Dick (2001) rightfully remind us that a
brand's market performance is driven by both the number of
individuals buying a particular brand and the frequency of repeat
purchases from these customers. The ability to manage these two factors
determines the extent to which a firm maintains and sustains its
customer base, as well as its market share. Indeed, Robinson (1979) and
Raj (1985) state that the larger the number of loyal customers, the more
secure will be the brand's market share. Therefore, as a priority,
all companies must both find ways to attract new customers to an
existing user base and to retain these buyers over the long term. So, it
must be that firms constantly battle with competitors to maintain or
increase both the number of buyers and the loyalty of these customers.
When a firm fails to hold a strong relative competitive position, it
runs the risk of a widespread phenomenon called "double
jeopardy" (DJ).
Double jeopardy is broadly characterized as a phenomenon whereby
small-share brands attract somewhat fewer loyal consumers, who tend to
buy the brand in smaller quantities, while larger-share brands are
purchased more often by customers who exhibit more loyalty (Ehrenberg
and Goodhardt, 2002; Badinger and Robinson, 1997, Donthu, 1994; Martin,
1973; Michael and Smith, 1999). Thus, less popular brands are punished
twice: (i) they have fewer buyers who show (ii) less loyalty to the
brands they buy. McPhee (1963) explained that DJ occurs when consumers
select between two brands of equal merit, one having a larger market
share and the other having a smaller market share. This does not
necessarily signify a weak small brand or a strong large brand. Rather,
it reveals that the smaller share brand is less popular than the larger
share brand for some reason (Pleshko and Souiden, 2007, Ehrenberg and
Goodhardt, 2002, Ehrenberg et al, 1990).
Although long established, the DJ phenomenon has a variety of
issues as yet unsettled (Ehrenberg and Goodhardt, 2002). For instance,
though previous research has found an obvious relationship between brand
share and loyalty in many instances, whether loyalty is a cause or a
result of high share remains unclear (McDowell and Dick, 2001).
Likewise, previous research has focused mainly on the issue of DJ for
the product brand while the relevancy for the company brand, the retail
brand, or the service brand is rarely discussed. Thus, the main
issue--'why two equally regarded brands or products differ in their
relative shares of the market?'--is still not truly defined in most
settings. Three possibilities may be drawn from the literature as
explanations for double jeopardy: (i) a familiarity effect, where buyers
are loyal to popular brands (c.f. Ehrenberg et al, 1990; McPhee, 1963),
(ii) an experience effect, where satisfied customers develop loyalty
(c.f. Tellis, 1988; Raj, 1982; Brown and Wildt, 1992; Johnson and
Lehman, 1997; Narayana and Markin, 1975; Nedungadi, 1990; Pleshko and
Souiden, 2007), and (iii) a design effect, where the better product wins
(c.f. Ehrenberg et al, 1990; Keith, 1960). Of these three, which are
most relevant will depend on the industry and circumstances.
DATA COLLECTION AND SAMPLE
The data for the current study are gathered from a group of
consumers who are mutual fund investors at banks in the state of Kuwait.
It was important to select a type of service that would add to the study
of double jeopardy, as we would expect to find differences based on
product-classes (Chaudhuri and Holbrook, 2002). In most cases, financial
services may be considered a shopping product because consumers make
decisions about these services using extended decision-making to choose
between many similar offerings (c.f. Murphy and Enis, 1986).
The sample, comprised of bank customers in the State of Kuwait, is
derived from a sampling frame provided by the Ministry of Planning. The
data are from self-administered questionnaires collected from visits to
households of both local citizens and foreign residents. This process
results in a total of seven hundred and seventy respondents, of which
three hundred and thirty are mutual fund investors and thus included in
the study. Note that the sampling methods employed a multi- stage
approach in order to ensure the sample proportions closely matched the
actual proportions of bank users in Kuwait. The sample also reflects the
distribution of residence over the six districts of Kuwait. Non-Response
was lower than ten percent, a seemingly acceptable number given the
sensitive nature of the information gathered. The quality of data was
ensured by the field data collectors who disqualified respondents
unwilling to share information about their banking activities.
Additionally, all questionnaires in Kuwait must be approved by a
government ministry, thus lending credibility to the research and
enhancing response rates.
Many financial services companies exist in Kuwait in a variety of
categories; however, only those companies offering mutual funds are
investigated in this study. At the time of this study, foreign banks
were not permitted to operate in the market and are therefore not
included in the study. Currently there are thirty-six companies offering
mutual fund services, with most of the activity handled through the ten
major banks of Kuwait. Thus, the ten banks are each included in the
study as individual entities, while the remaining twenty-six providers
are grouped together into an 'other' category due to the small
market shares. Therefore, there are eleven 'banks' that will
be included in the analyses regarding mutual fund investors; the ten
major banks by market share, along with an 'other' category
which includes the averages of twenty-six banks and financial services
companies. Table 1 summarizes the banks and investors data derived from
the respondents.
From Table 1 many items are noted regarding the sample: (i) the
banks are identified in the first column, (ii) the number of investors
for each bank from the sample are shown in the second column, (iii) the
number of investors from the sample pertaining to the banks where the
investors have the largest proportion of money invested is shown in
column three, (iv) the total number of mutual fund accounts held by the
investors in the sample is shown in column four, and finally (v) the
total mutual funds investments in Kuwaiti dinars (Kd) is revealed in
column five. It is noteworthy to see that investors may have more than
one mutual fund investment account. Additionally, the investors may have
mutual fund investments at more than one bank. Thus, the numbers will
show that there are more investors (column two) and accounts (column
four) than total investors. However, column three shows the bank where
the customer has the majority of their investment money and those
numbers will add approximately to the number of respondents (330): two
hundred forty seven (three not grouped) associated with the ten major
banks and eighty with the other banks.
When one considers investments with multiple banks, the three
hundred thirty respondents in the study count as five hundred and thirty
investors across the thirty six banks (see Table 1, column two).
Additionally, these investors have a total of seven hundred and
thirty-two mutual fund investments in Kuwait (see Table 1, column four).
These mutual fund investments total approximately Kd16,538,179.
Eighty-four percent are associated with the ten major banks and the
remaining sixteen percent invested in the other twenty-six banks.
MEASUREMENT
The study includes a variety of constructs pertaining to market
share and consumer loyalty. The overall numbers for the three market
share indicators and the single loyalty indicator are derived by summing
across the respondents to arrive at aggregate sample totals for each
bank. These overall measures are percentages for the market shares and a
frequency for loyalty. The indicators are described below and are
derived from research in other industries where similar measures are
shown to be reliable and valid for aggregate measures within services
retailers (Pleshko, 2006). The aggregate market share and loyalty
indictors are revealed in Table 2 for each of the banks. Note that these
are the data used in the DJ analyses to be described later. Note that to
gather the data, the respondents were asked to write the bank,
investment amount, and year initiated for each mutual fund investment.
The first market-share indicator (MSFI) refers to the share of
investors that each bank holds. As previously noted, there are more
investors than sample respondents due to multiple accounts held by each
investor (see column two, Table 1); the total investors are actually
five hundred and thirty. Thus, MSFI is calculated as follows: MSFIi =
Si/530, where 'S' refers to the data from column two in Table
1 and 'i' refers to the specific bank. So, regarding Bank 33
for example: MSFI33 = 74/530 = 13.96%. From Table 2, it is noted that
the range of MSFI is from a low of 0.78% for 'other' banks to
a high of 17.74% for Bank 17.
The second market-share indicator (MSFA) refers to the share of
mutual fund accounts/investments that each bank holds. As noted
previously, there are more accounts than respondents (see column four,
Table 1); the total accounts are seven hundred thirty-two. Thus, MSFA is
calculated as follows: MSFAi = [T.sub.i]/732, where 'T' refers
to the data from column four in Table 1 and 'i' refers to the
specific bank. So, regarding Bank 33 for example: [MSFA.sub.33] = 99/732
= 13.52%. From Table 2, it is noted that the range of MSFA is from a low
of 0.76% for 'other' banks to a high of 19.13% for Bank 17.
The third market-share indicator (MSVA) refers to the share of
money invested that each bank holds. Recall from the previous paragraphs
that the total value of the respondents' investments in mutual
funds is Kd16,538,179. Thus, MSVA is calculated as follows: [MSVA.sub.i]
= [Z.sub.i]/16,538,179, where 'Z' refers to the data from
column five in Table 1 and 'i' refers to the specific bank.
So, regarding Bank 33 for example: [MSVA.sub.33] = 3,083,503/16,538,179
= 18.64%. From Table 2, it is noted that the range of MSVA is from a low
of 0.61% for 'other' banks to a high of 23.61% for Bank 17.
The three market share indicators appear to be reliable equivalent
forms of the same concept, as they are significantly and positively
related as analyzed by the Spearman rank-order test. The relationships
are as follows: MSFI-MSFA (rho=0.97, p<.01), MSFI-MSVA (rho=0.90,
p<.01), and MSFA-MSVA (rho=0.88, p<.01).
The loyalty indicator (LOYF) refers to the number of mutual fund
investors at each bank. Specifically, LOYF is defined as the number of
investors at each bank, where the investors are assigned to a specific
bank only when they have the largest investment from their total mutual
fund monies at that bank. You may recall from previous paragraphs that
the total number of classified respondents is three hundred and
twenty-seven. So, regarding Bank 33 for example: [LOYF.sub.33] = 45,
which are 13.76% (45/327). From Table 2, it is noted that the range of
LOYF is from a low of three (0.91%) for 'other' banks to a
high of forty-six (14.06%) for Bank 17.
ANALYSIS/RESULTS
The Spearman (1904) rank correlation coefficient is used to analyze
the association between market share and the variables under
investigation. Spearman's test statistic, rho or "r", is
calculated with data taken from 'n' pairs (Xi, Yi) of
observations from the respondents on the same objects, the retail brand
outlets. In this study, market share makes up one of the observational
items in the pair, while loyalty is the other item. The observations
within each pair of variables is then ordered from smallest to largest
and assigned the respective ranks from one to n, where n refers to the
number of banks: eleven in this case. The construct values, rankings,
test statistics, and '//-values are shown for each construct of
interest in Table 2 and Table 3. Ties are assigned the average ranking
value. These "rankings pairs" are then used to calculate the
test statistic, "rho", which is also represented in this study
as "r".
To calculate the "r", the "rankings pairs" are
compared: this would include each of the market share indicators being
compared separately to customer loyalty (LOYF). The test statistic, rho,
is calculated as follows: r=1-6[Sum(d2)/n(n2-1)]. In the equation, W
equals the number of paired rankings (in this case, eleven) and 'd
equals the absolute differences between the rankings for each bank. The
test statistic ranges between +1 (perfect positive association) and -1
(perfect negative association).
In this study, two-tailed tests are performed, giving the general
hypotheses for the paired variables: Ho: independently ranked pairs (no
relationship between the rankings of loyalty and share) or Ha: related
ranked pairs (relationship between the rankings of loyalty and share.
Table 3 reveals the results of the analysis.
As noted in Table 3, the rank ordering of the loyalty indicator is
significantly related to the rank orders of all three market share
indicators. The test of LOYF-MSFI (rho=+.7932, /?<01) shows a
significant positive relationship. The test of LOYF-MSFA (rho=+.6795,
/><05) shows a significant positive relationship. Also, the test
of LOYF-MSVA (rho=+.8523, /?<01) shows a significant positive
relationship. Thus, three out of three statistical tests support the
existence of double jeopardy in Kuwait banks' mutual fund
investment services, as tested across banks.
DISCUSSION/LIMITATIONS
The findings of this study reveal that the concept of double
jeopardy (DJ) does apply to banks which are mutual fund providers in the
state of Kuwait for the given sample. The rank orders of market share
and loyalty are significantly and positively related in all three
statistical tests, revealing a strong DJ effect. The use of multiple
indicators (and thus the multiple tests) allows greater confidence in
the conclusions of the study than would be possible without multiple
equivalent measures. Thus, we can conclude that banks with larger shares
in mutual fund services also have larger percentages of loyal buyers and
vice versa.
This finding adds additional support to the relevance of Double
Jeopardy in retailing and/or service providers, which are distinct from
the brand names which they market. Regarding other retail categories,
research using similar methods has shown DJ to be strongly evident in
other banking services (consumer loans) and fast-food outlets (Pleshko
and Al-Wugayan, 2008; Pleshko et al, 2006). Thus, it appears that double
jeopardy is an important strategic issue for managers not only dealing
with FMCG products, but also for service and retail providers.
The presence of DJ in banking services may be related to the
generally well-recognized brand names that are evident in the banking
industry. Or the DJ effect might be a result of the high involvement
levels associated with these types of services. In other words, maybe DJ
is more prevalent with shopping or specialty products than with
convenience or preference goods (Murphy and Enis, 1986). This would be
contrary to the findings of Lin and Chang (2003), who suggest the DJ
relationship to be stronger in low involvement products.
The readers must wonder if the current findings are indicative of
general tendencies or simply a characteristic of this limited study in
the Kuwaiti market. More and varied studies taken over time are probably
needed to truly identify the scope of the double jeopardy phenomenon in
banking. Additionally, this study only addressed mutual fund
investments: no evidence is provided that these findings apply to other
banking services, such as business loans or money transfers. Future
research might also include both different target respondents
(commercial banking) as well as different product-markets, both in the
banking sector and elsewhere.
IMPLICATIONS
As double jeopardy is shown to be evident in this part of the
banking sector, there are definite implications for the competitors
within the industry. As the DJ name implies, this may reveal a future
problem for the smaller Kuwaiti banks which offer investment services.
Smaller Kuwaiti banks are faced with, not only lower market shares, but
with smaller numbers of brand loyal buyers. The result of having fewer
loyal buyers is that the smaller-share banks will (theoretically)
gradually lose market share to the larger banks as time progresses. This
digression in share occurs as buyers switch among the banks from
small-share to large-share and vice versa (c.f. Bandyopadhyay et al,
2005). But with fewer buyers switching to the smaller share banks, in
the long run these small banks may end up with even smaller shares. This
long-term digression may be prevented with an active marketing program
aimed at increasing loyalty within the users of the smaller banks. In
this way, even though the banks have smaller shares, they will be able
to rely on an equally strong loyalty base for future business.
The prognosis for larger banks is the opposite. Larger share banks,
assuming continued high-quality managerial decision making, should end
up growing even larger in the long-term. The large-share banks are
facing a much better situation. Due to the advantages of having a large
share to begin with (familiarity, stronger brand names, better
performance, etc.), these larger banks do not face the digression in
market share expected with the smaller banks. On the contrary, the
large-share banks should ideally increase market share, due to gaining
switchers from the small banks and a larger share of newcomers, as long
as loyalty levels remain high relative to the smaller banks. Thus, large
banks can focus, as might normally be expected, on expanding the market
size. This focus on market size for larger-share banks should lead to a
larger percentage of growth than smaller-share banks would expect.
But this gradual movement within the industry to fewer and larger
banks might take longer than expected in other industries due to the
peculiarities of this type of service. Investment services generally
have a longer purchase cycle. Considering this purchase cycle, it might
be years before a second or third investment decision is made again and
a switching decision might occur. Thus, the medium to long terms
inherent with fund investments helps ensure that business remains with
the originally selected bank, unless a problem occurs within the market
or a specific bank. Again, these low levels of switching, once a bank
service is selected, makes it more difficult for the smaller- share
banks to gain share.
Finally, this study and the findings are particularly relevant for
the Kuwait bank sector as the market opens up to foreign competition in
line with WTO requirements. It may be that the local banks feel
confident with their current shares, due to the existence of loyal
buyers for each bank. This confidence may be folly. As the new
multinational banks enter, and upon seeing difficulty in gaining share
from the existing customer groups in current service areas, they may
well focus on expanding the market size by targeting current nonusers or
new segments of the industry. Even though DJ applies to mutual fund
services in the existing markets of Kuwait, this will most likely not be
evident in new segments of the market. Any carryover effect of DJ from
one service to another for each bank has no support at the current time
as no one is studying this issue. Therefore, local banks in the current
segments should have advantages over new-entrant foreign banks within
the current buying market. However, this DJ advantage may not be evident
within new segments. The results of large global foreign banks entering
new segments could be disastrous in the long run for not only the
smaller-share banks, but maybe even for some of the larger-share banks
as well. Therefore, while Double Jeopardy may be a viable barrier to
entry or competitive tool for current markets, there are no guarantees
that this phenomenon will protect large-share banks during future
endeavors into new markets or new service areas.
