1. Introduction
Customers are increasingly using multiple channels, as they have become familiar
with using various interface technologies. In the last years we have witnessed the rise of the
web-based shopping platform, while more recently we observed the birth of the mobile-based
channel. Given these new developments, retailers hope to maximize their profits by pursuing
the optimal multichannel retailing strategy. However little is known about how firms should
manage the customer’s use of the different channels. It is often the case that the customer’s preferred purchasing channel does not coincide with what the retailer sees as the optimal
shopping channel. To overcome this undesired situation, the firm can offer monetary
incentives to itscustomers to “smoothen” their migration to the channel preferred by the firm.
We explore which are the most common monetary incentives used in literature and develop
hypotheses with respect to the effectiveness of the incentives in convincing customers to
migrate to the desired channel.
The aim of the current study is to identify if companies can convince customers to
switch shopping channels and what is the optimal framing of the monetary incentives offered
to customers, in the context of right-channeling them. In an experiment, we present
participants with four different framings of the monetary incentives: absolute-price-reduction,
relative-price-reduction, gift and price-reduction-for-future-purchases, and then measure the
participants’ attitudes towards the retailer and the intention to switch channels, in the context of purchasing a laptop (setting 1) and a touristic package (setting 2). We argue that the
framing of the incentive offered to customers to switch shopping channels influences the
attitude towards the retailer and the customers’ purchase intention. More specifically, we hypothesize that an absolute-price-reduction will lead to better outcomes in comparison to a
relative-price-reduction. Furthermore, we suggest that a gift offered as incentive to customers
relative-5
price-reductions, in terms of customer response. Finally, a
price-reduction-for-future-purchases would have the worst outcomes of all the four framings used in our research design.
The relevance and timeliness of our study stem from the important increase in the
number of channels that a company can use to sell its products and services. However, the
profitability often varies considerably across the different channels. After identifying the most
profitable distribution channel, firms face the daunting process of convincing their customers
to migrate to the channel preferred by the firm. Our research will contribute to the
multichannel marketing literature by investigating if it is possible to persuade customers to
change their shopping channel, and by identifying whether there are differences in the
attitudes and intentions of customers, as a result of different framing of the incentives used by
firms in order to optimize their customers’ channel migration. The findings of our research support marketing managers by providing them with a set of guidelines on how to persuade
customers to buy from the desired channel (what is the optimal framing), in what context this
is possible (boundary conditions), and what are the expected success rates, with implications
on the resource and communication management of firms.
In the following sections of the paper we firstly present several examples of academic
papers focusing on channel migration and comparisons between different channels in terms of
customer-related consequences. Secondly, we look at incentives and review the academic
literature which investigates the use of different framings for monetary incentives on which
our study is focused. Thirdly, we identify gaps in the literature, we formulate our research
question and then develop the hypotheses. In the subsequent section we outline the
methodology used in our study. Finally, we wrap up by giving a preview of the potential

2. Literature review
2.1. Channel choice. Channel migration
Multichannel retailing is “the set of activities involved in selling merchandise or
services to consumers through more than one channel” (Levy & Weitz, 2009). Over the past decade, multichannel retailing environments have grown in variety, scope, and sophistication
(Dholakia et al., 2010). Therefore there is an increasing need to optimize the multichannel
environment, through multichannel customer management, which can be defined as “the design, deployment, and evaluation of channels to enhance customer value through effective
customer acquisition, retention, and development” (Neslin et al., 2006).
Customers frequently use different channels at different stages of their
decision-making and purchase processes. To give an example, it is not unusual that customers look for
deals on the internet, urgent purchases in stores, place customized and complex orders by
telephones, and offer gifts through catalogs. Previous research (Balasubramanian et al., 2005;
Dholakia et al., 2010) shows that customers use channels to satisfy the following goals:
economic goals (obtaining a good deal), self-affirmation goals (demonstrating expertise in
channel selection and use), symbolic meaning goals (being thoughtful and thorough during
the shopping process), socialization and experiential goals (being part of social world and a
stimulating environment), and routine or script maintenance goals (achieving regularity and
familiarity in the shopping process). Channel choice can also be driven by customers' price
expectations, the category of product being purchased, perceptions of switching costs,
efficiency concerns, risk aversion, and demographic characteristics (Dholakia et al., 2010;
Inman, Shankar, & Ferraro, 2004). In their study of Dutch consumers, Konuş, Verhoef, and
Neslin (2008) identify three separate multichannel segments. The first segment is labeled as
7
channels covered in the study (i.e. stores, the internet, and catalogs), high innovativeness and
see shopping as a pleasant experience. The members of the second segment, the
“store-focused consumers”, are inclined towards brick and mortar stores and have high levels of
brand and channel loyalty. Finally, the third segment, the “uninvolved shoppers” includes
shoppers that have little interest in any of the channels and their shopping involvement is low.
Channel choice is not static since it changes over time, as customers migrate from one
channel to another. Next, we present several examples of academic papers which focus on
channel migration and comparisons between different channels in terms of customer-related
consequences. Ansari, Mela, and Neslin (2008) analyze the migration of customers across
various channels and find that a significant segment migrated from traditional channels to the
Internet and subsequently purchased less when compared to other segments. They explained
this finding by suggesting that migration to the internet lowered customers' switching costs,
and the attendant lack of personal contact reduced customers' loyalty to the retailer. In their
2004 study, Gupta, Su, and Walter reveal that 52% of multichannel shopper migrated from
offline to online channels across different product categories. Their channel migration
behavior was predicted by channel risk perceptions, price search intentions, evaluation effort,
and waiting time, but unrelated to customer demographics.
Channel migration can also be driven by the vendor firm. Sullivan and Thomas's
(2004) study of customer channel migration across stores, catalog, and Internet shopping,
show that analyses can be conducted to enhance the targeting and management of customers
in a multichannel context with the goal of forecasting shifting channel choices over time.
Building on their study, we aim to identify how companies can convince customers to switch
shopping channels by offering them monetary incentives, in the following section of our
8
we review the literature which compares the effectiveness of the different framings for
monetary incentives.
2.2. Incentives in customer management
An incentive is something that motivates an individual to perform an action. Oliver
(1984) makes a distinction between positive and negative incentives. In inducing collective
action as a group, positive incentives are defined as “if everyone cooperates, everyone should be rewarded”, whereas negative incentives are the opposite “if everyone cooperates, no-one gets punished, but if everyone defects, everyone will be punished”. In the context of dilemma games, Oliver (1980) shows that punishments, not rewards, are predicted to be effective for
enforcing cooperation, however, many players experienced harmful effects of punishment by
increasing the risk of retaliatory spirals. Moreover Oliver (1984), reviewing the literature,
arrives to the same conclusion: punishments are more effective than rewards for producing
cooperation by a group of subjects. However, as inducements for individual compliance, there
is no difference between rewards and punishments.
Andreoni, Harbaugh, and Vesterlund (2003) suggest that less cooperation is expected
in societies where positive behavior is rewarded than in those where negative behavior is
punished, however, for maximum efficiency, reward and punishment should be used
simultaneously as incentives. The same authors, support their statement by giving real live
examples: “some universities now use a combination of raises and differential teaching loads to encourage good performance. Similarly, procurement and production contracts and
government regulations in areas ranging from meat inspection to sulphur dioxide pollution
often include both bonuses for good performance and various sorts of clawbacks for bad
9
According to Dollman (1996) incentives can be monetary rewards – usually money,
solidary rewards (e.g. socializing, camaraderie), status rewards (e.g. prestige, recognition) and
purposive rewards (e.g. a sense of group mission). In the context of choice experiments,
Beattie and Loomes (1997) posit that monetary incentives are very powerful so that, instead
of using the simpler approach of dealing with each decision in turn, subjects undertake the
demanding task of processing large sets of problems simultaneously.
Customer management literature has focused mainly on monetary incentives. We refer
to monetary incentives when there is an agent (i.e. the customer) that expect some form of
material reward – especially money – in exchange for acting in a particular way (i.e. migrate
from one channel to another). In our study we use equivalent monetary incentives with
different framings: absolute-price-reduction, relative-price-reduction, gift and
price-reduction-for-future purchases.
2.3. Monetary Incentives: The Effect of Framing
The fact that cognitive judgments are influenced by the way in which decision
problems are framed is well established (Kahneman & Tversky, 1984). As Sinha and Smith
(2000) point out, customers often exhibit economically non-rational behaviors as a result of
contextual cues, including semantic cues, they derive from price offers. In other words, the
way in which price offers are framed influences the customer’s response to them.
Framing is "the way the story is written or produced, including the orienting headlines,
the specific words choices and the rhetorical devices employed” (Druckman, 2001). Framings
often have an important role in shaping the decision-making process. The equivalency
10
employment vs. 5% unemployment or, 97% fat-free vs. 3% fat) cause individuals to change
their preferences.
Framing may affect customers' estimates of the received value and, hence, choice also
in the context of assessing a monetary incentive (i.e. price promotion) (DelVecchio, Krishnan,
& Smith, 2007). The framing of price promotion may affect whether customers calculate the
revised price. It appears that some customers, but not all, calculate the revised price stemming
from a price reduction. Framing is likely to influence the chance of a discount being
transformed into a revised price rather than being perceived in general terms or ignored
altogether. When customers are exposed to a discount, the likelihood that they will compute
the new price is expected to be a function of the ease of calculating that price. Calculating the
new price resulting from absolute-price-reduction requires a customer to read the regular
price, to read the discount, and then to subtract the discount from the regular price.
Subtraction is a relatively easy task that results in a high level of accuracy compared to
calculating percentages. Given the computational ease, customers are likely to calculate the
price associated with an absolute-price-reduction and should be accurate in their calculations.
In contrast to an absolute-price-reduction, a relative-price-reduction requires an additional
processing step; the percentage must be multiplied by the base price to find the value of the
discount. Beyond requiring an additional step, the multiplication process required is relatively
difficult, which makes relative-price-reductions harder to calculate than
absolute-price-reductions. Such difficulty should make customers less likely to compute the revised price
and, even if they perform the calculation, they may be uncertain of the resulting price because
of the higher difficulty. Hence, when discounts are framed in terms of
relative-price-reduction, both failing to calculate the revised price and lower confidence in the accuracy of
the calculation should result in less weight being placed on the perceived price resulting from
11
Interestingly, when consumers are asked to provide their general sense (without
engaging in any calculations) of whether a promotion is large or small, they tend to perceive
relative-price-reductions as larger than equivalent absolute-price-reductions (Krishna et al.
2002). Thus, when customers do not calculate the value of a promotion,
relative-price-reductions should lead to greater choice (DelVecchio et al., 2007). However, when customers
are motivated to calculate its value, the difficulty of estimating the value of a
relative-price-reductions should result in uncertainty regarding the resulting price. Therefore, customers
should be more influenced by an absolute-price-reduction more than a relative-price-reduction
when they are motivated to calculate the discounted value.
Das (1992) found that the “mere phrasing” of a deal influences the deal’s evaluation and purchase intention. Generally, the “2 for $x” and “Buy 1, get 1 at half price” framings
produced higher deal evaluation and higher purchase intentions. These effects were
moderated by price. At a high price, the “save $n on purchase of 2” was equally effective as the two volume discounts, suggesting that customers’ reaction to semantic cues is also
dependent on the total financial implication of the deal.
In a later study, Sinha and Smith (2000) show that consumer perceptions of
transaction value varies across economically equivalent price promotions. In a laboratory
experiment involving US college students, Sinha and Smith (2000) concluded that, overall, a
relative-price-reduction (“50 per cent off”) was more attractive than a volume promotion
(“buy one get one free”), which in turn was more attractive than a mixed promotion (“buy 2, get 50 per cent off”; equivalent to “two for the price of one”).
In their study, Chen et al. (1998) hypothesized that, for high-priced items, customers
will see a price reduction framed as absolute-price-reduction as more significant than a
relative-price-reduction, and that the opposite would be true for low-priced products. Their
12
higher for higher priced products, whereas, for a given absolute price discount, the relative
percentage reduction is higher for lower-priced products. Chen et al. (1998) tested this
proposition in a study that used a $1595 computer, a $7.95 box of floppy disks and a 10%
discount at each price level. The study confirmed the authors’ hypothesis. However, while the
framing of the price discounts influenced the respondents’ evaluation of these discounts it did not have a significant influence on purchase intentions. Similar results were found by Gendall
et al. (2006) who show that for high priced items, such as stereos and computers, framing a
discount as absolute-price-reduction was significantly more effective than expressing it as
relative-price-reduction.
2.4. Literature gap
Customers are increasingly shopping across multiple channels of the same retailer.
While many retailers recognize that these multichannel shoppers are the most profitable, little
is understood about how firms should optimize the customers’ use of the different channels. The presumption of a customer segmentation multichannel strategy, and even of a
cost-reduction strategy, is that certain customers should use certain channels (Neslin et al., 2006).
In the ideal situation, the firm simply provides a list of potential channels and the customer
can self-select itself into the appropriate channel. The problem is that customers may not
naturally use the channel that the retailer sees as optimal. Hence, the question that arises is
should customers be encouraged to use certain channels? Moreover, how can the firm
accomplish this? The main danger is that customers may be turned off by being forced into
using channels contrary to their preferences. In order to avoid this, the firm can provide
13
By reviewing the existing literature in the field of channel migration, optimization of
the multichannel strategies and use of different incentives, we fail to identify any study that
focuses on what a company should do in order to move its customers to the channel preferred
by the company, which type of incentive should it use and which is the recommended framing
for that specific incentive. Furthermore, no previous study focuses on the optimization of
marketing communication and marketing resources by using the best incentives in firm driven
channel migration setting. In order to overcome this gap we aim we investigate how
customers respond to equivalent monetary incentives with different framings, in the context of
convincing customers to shop from the internet site instead of the classical brick-and-mortar
store.
The reason why we focus on web-based shopping as the preferred channel is that it has
been observed that the web-oriented “migration” segment has the highest sales volume
(Ansari, Mela, & Neslin, 2008). The setting that we use in our experimental design is
relevant, since numerous firms try to shift the channel use behavior of their customers by
using incentives. The results of our research have the potential to support marketing managers
by providing them with the optimal framing that they should use for the monetary incentives
in the context of persuading customers to switch shopping channels.
2.5. Hypotheses development
Framings often have an important role in shaping the decision-making process.
Framing of decision problems influence cognitive judgments (Kahneman & Tversky, 1984).
Often, the framing of different, but equivalent, words or phrases causes individuals to change
their preferences. The way the incentives based on reduced price are framed induce
14
way in which price offers are framed influences the customer’s response to them. Following
this rationale we formulate the following hypotheses:
H1a: The framing of the incentive offered to customers to switch shopping channels
influences the attitude towards the retailer.
H1b: The framing of the incentive offered to customers to switch shopping channels
influences switching rate to the desired channel (web-store).
Because customers, being faced with a price reduction, calculate the revised price of
the product or service, the ease with which they do this calculation influences the estimation
of the revised price (DelVecchio et al., 2007). Calculating the revised price resulting from
absolute-price-reduction requires a customer to read the regular price, read the discount, and
then subtract the discount from the regular price. These multiple and sometimes complex
operations, increase the uncertainty felt by the customers, because they fear that their
calculation is not accurate. In contrast, given the computational ease, customers much more
easily calculate the revised price associated with an absolute-price-reduction and should be
accurate in their calculations. Hence, absolute-price-reductions should be more effective in
comparison to relative-price-reductions.
H2a: In the context of equivalent monetary incentives, an absolute-price-reduction (vs.
a relative-price-reduction) will lead to a better attitude towards the retailer.
H2b: In the context of equivalent monetary incentives, an absolute-price-reduction (vs.
15
Campbell and Diamond (1990) argue that monetary promotions were more noticeable
to consumers than nonmonetary promotions. They provide an example in which they show
that a $5 discount offered by Kodak for the purchase of a new camera is more noticeable than
an offer of two free rolls of film that can even have a higher value than $5. A possible
explanation of this is that gifts offered as incentives are perceived as suboptimal by the
customer. With money they can purchase whatever they wish, but by receiving a gift of the
same value, they are bound to not having a choice. Building on this reasoning we hypothesize
that:
H3a: In the context of equivalent monetary incentives, a gift offered as incentive to
customers to switch shopping channels (vs. absolute-price-reduction and
relative-price-reduction incentives) negatively influences the attitude towards the retailer.
H3b: In the context of equivalent monetary incentives, a gift offered as incentive to
customers to switch shopping channels (vs. absolute-price-reduction and
relative-price-reduction incentives) negatively influences the switching rate to the desired channel.
Munger and Grewal (2001) state that “retailers and marketers need to be aware of the extent to which perceptions of the time and effort are involved in redeeming different types of
discounts”. Indeed, customers value their time. The time and effort involved with redeeming the price-reduction-for-future-purchases is likely to have a negative effect of customer
perceptions and reduce their purchase intentions. Research done by Folkes and Wheat (1995)
suggests that because of the temporal distance involved in getting the discounts associated
with the future purchases customers are likely to evoke price perceptions similar to regular
prices than discounts. Furthermore, consumers tend to see future outcomes less favorable then
immediate outcomes. Thus, price-reduction-for-future-purchases are likely to be viewed as
16
H4a: In the context of equivalent monetary incentives, a
price-reduction-for-future-purchases (vs. other incentives) negatively influences the attitude towards the retailer.
H4b: In the context of equivalent monetary incentives, a
price-reduction-for-future-purchases (vs. other incentives) negatively influences the switching rate to the desired
channel.

3. Methodology
3.1. Experimental design. Manipulation.
In order to test our hypotheses we performed a single factor between-subjects
experimental design in which we manipulate the monetary incentives. We chose the
experiment as our research strategy because have four different, but value-equivalent,
framings and we intend test them in a controlled environment. We want to make sure that the
variance in the dependent variables is a consequence of the experimental manipulation, and,
thus, we can draw a clear causality between the manipulated variable and the dependent
variables.
We conducted this experiment in two different settings, as dictated by the different
scenarios used. The only difference between the two settings is that in setting 1, participants
are faced with the context of buying a laptop, whereas in setting 2, participants are purchasing
a touristic package. This allows us to make infer whether products differ from services in how
customers react to the different framings of the monetary incentives. In both settings, the four
different types of monetary incentives represent the experimental conditions:
absolute-price-reduction vs. relative-price-absolute-price-reduction vs. gift vs. price-absolute-price-reduction-for-future-purchases. These
monetary incentives are equivalent in value. The context of the manipulation is the purchase
of a laptop at the store price of 500 euro in setting 1, and a touristic package with a store price
of 900 euro in setting 2. Different incentives (each is the basis of one the 4 different
experimental conditions) are offered to participants in order to persuade them into shopping
for the produc/service using the online platform. Participants in the absolute-price-reduction
condition are offered a 25 euro discount (45 euro in setting 2), participants in the
relative-price-reduction are offered a 5% discount on the store price, participants in the gift condition
18
price-reduction-for-future-purchases condition are offered a discount of 25 euros at the next
order from the retailer (45 euro in setting 2).
3.2. Participants
Because of the limited resources allocated to this project and also because its main
purpose is didactic, the participants in these scenario-based experiment are students who were
asked to fill in an online questionnaire. The participants were randomly assigned in the 4
experimental conditions. The participants are Facebook users who are acquaintances of the
researcher, mostly students. In setting 1, 85 participants (38% male; Mage = 25.9, SD = 4.7;
Romanian 87%, Dutch 8%, other nationalities 5%) filled in the questionnaire. In setting 2, 94
participants (50% male; Mage = 23.7, SD = 2.9; Romanian 46%, Dutch 24%, other
nationalities 30%) filled in the questionnaire. The nature of the online questionnaire did not
allow missing data.
3.3. Procedure
Both settings of the experiment were based on online questionnaires. Upon following
the link to the experimental web site, participants were welcomed and told that the data
collected through the questionnaire will be treated anonymously and for statistical purposes
only. Subsequently, the participants were presented with a scenario. The begin by asking
participants to imagine that they are in a shopping setting in a brick-and-mortar store and that
they have found a laptop (a touristic package in setting 2) that they want to purchase. The
participants are further instructed that when they approach the selling personnel in the store,
they are told that the retailer has an offer for them, if they agree to purchase the laptop
(touristic package in setting 2) from the online shop of the same retailer. The nature of the
offer represents the manipulation. Each participant will only receive one of the four offers,
19
participant has received the offer, they are asked to respond to the items measuring the
customers’ switching rate and the attitude towards the retailer. After this, the participants fill in the control variables. Finally, participants are thanked for their participation.
3.4. Dependent variables
We measured the effect of the monetary incentives (the manipulated independent
variable) on the customers’ switching rate to the desired channel and on the attitude towards the retailer (dependent variables). The switching rate was measured using two separate items:
Would you agree to purchase the laptop from the (name of retailer) online shop, after
receiving the offer? “Yes” or “No”
How likely is that you buy the laptop from the online shop? 1 Not likely at all – 7 Very much
likely
The attitude towards the retailer (referred from now on as “Attitude”) was measured using a
scale with four items adapted from Fiore, Kim, & Lee (2005):
How did this affect your attitude towards (name of retailer)? 1 very negative – 7 very positive
(name of retailer) offers good services. 1 I Strongly disagree – 7 I Strongly agree
How favorable is your overall evaluation of (name of retailer)? 1 Very bad – 7 Very good
I would recommend (name of retailer) to my friends. 1 Not likely – 7 Very likely
3.5. Control variables
The control variables measured in our experiment are impulsiveness, time pressure,
online shopping behavior and the socio-demographical variables gender, age, nationality and
years of formal education. For detailed measures, please consult the questionnaires (Appendix

4. Results
4.1. Manipulation Check
The manipulation check was tested using the question “What kind of incentive was
offered to you in order to convince you to buy from the online shop?” with multiple choice
response. The choices represent the four different framings used for the equivalent monetary
incentives. In the first setting, only 46% of the participants mentioned in the manipulation
check variable the correct framing that they received at the beginning of the questionnaire. In
the second setting, 71% of the participants have passed the manipulation check. The subjects
that failed the manipulation check were removed from further analyses, thus the remaining
sample sizes are 39 for the first setting and 67 for the second setting; somewhat low numbers
taking into account the 4 experimental conditions. In this context, the study is slightly
underpowered, which may lead to type 2 errors.
4.2. Hypotheses testing for experimental setting 1
Table 1. Descriptive statistics and correlation matrix of the dependent variables, for experimental setting 1 Variable Descriptive statistics Correlation with 1 Correlation with 2 Correlation with 3
1. Attitude towards retailer M = 4.96, SD = 1.1 - 0.4 0.25
2. Purchase intention (Likert) M = 5.23, SD = 1.6 0.4 - 0.62
3. Purchase intention (dichotomous) Yes 87%, No 13% 0.25 0.62 -
Before we proceed to hypothesis testing, we computed the (unweighted) scale mean
for Attitude, by averaging the scores of the 4 items that constitute the scale. The reliability of
the scale is Cronbach’s Alpha = 0.864, hence we can consider the Attitude scale as reliable.
In the above table we can see the correlation coefficients between the dependent
21
significant at the 1% significance level, the 0.4 correlation coefficient between attitude
towards retailer and purchase intentions measured with the Likert scale is significant at the
5% significance level, while the 0.25 correlation coefficient between attitude towards retailer
and purchase intentions measured with the dichotomous scale is not significant.

Absolute Percent Mean Attitude Purchase Intentions (Likert) Purchase Intentions - Yes (dichotomous) 1 - absolute-price-reduction 11 28.2 4.8636 5.00 82% 2 - relative-price-reduction 13 33.3 4.8462 5.31 92% 3 - gift 8 20.5 4.9688 5.50 88% 4 - price-reduction-for-future-purchases 7 17.9 5.2857 5.14 86%
In testing the hypotheses, several statistical analyses were performed. Some of our
hypotheses involve differences in means of variables such as attitude towards the retailer and
purchase intention measured with the Likert scale. These hypotheses were tested with the
t-test when only two conditions were compared and with ANOVA when more than two groups
were compared. Other hypotheses refer to the effect of the framing of incentives on purchase
intentions measured dichotomously. Such hypotheses were tested with the Chi-Squared test
and with logistic regression (which, in contrast to the Chi-Square test, allows control
variables).
4.2.1. Testing hypothesis 1a
An ANOVA (F(3,35) = 0.26, p = ns) was performed on Attitude, therefore the
hypothesis that framing of the incentive offered to customers to switch shopping channels
22 4.2.2. Testing hypothesis 1b
An ANOVA (F(3,35) = 0.15, p = ns) was performed on purchase intention (Likert),
therefore the hypothesis that framing of the incentive offered to customers to switch shopping
channels influences purchase intentions is not supported. These results are consistent with
testing this hypothesis using the depend variable measured dichotomously, as shown by the
Chi-Square test (Chi-Square(3) = 0.6, p = ns). Next, we test the hypothesis, by performing a
logistic regression on the dependent variable purchase intention, measured dichotomously.
The independent variable is framing of monetary incentives while gender, frequency of online
purchases (number of online purchases in the last 30 days), impulsiveness and time pressure

We use the likelihood ration test to evaluate model fit. The likelihood value can be
compared between equations (intercept only model, and final model) to assess the difference
in predictive fit from one equation to another, with statistical tests for the significance of these
differences. We follow the approach presented in Hair et al. (2010). The first step is to
calculate a null model, which acts as the baseline for making comparisons of improvement in
model fit. The null model is one without any independent variables. The logic behind this
23
independent variables can he compared. The second step is to estimate the proposed model,
containing the independent variables included in the logistic regression model. Hopefully,
model fit will improve from the null model and result in a lower -2 Log Likelihood value. The
final step is to assess the statistical significance of the -2 Log Likelihood value between the
two models (null model versus proposed model). If the statistical tests support significant
differences, then we can state that the set of independent variables in the proposed model is
significant in improving model estimation fit. In the model that we tested, the model fit of the
proposed model is not significantly better than the empty model, as shown by the
Chi-Square(7) = 2.18, p = ns. This means that the predictor variables fail to explain a significant
amount of variation in the dependent variable.

As we can see in the table above, the likelihood ratio tests show that all variables

Attitude (t(22) = 0.04, p = ns), nor purchase intention (Likert) (t(22) = -0.4, p = ns). We
conclude that hypotheses 2a and 2b are not supported. Hypothesis 2b was also tested using the
dependent variable in which purchase intentions were measured dichotomously, but both the
Chi-Square test and the logistic regression failed to reject the null hypothesis.
4.2.4. Testing hypotheses 3a and 3b
In order to test hypotheses 3a and 3b, we had to build the contrast between the gift condition
and the absolute-price-reduction and relative-price-reduction conditions. We did this by
recoding the variable condition so that the gift condition is coded with 1 while both the
absolute-price-reduction and relative-price-reduction conditions are coded with -0.5. After
doing this we tested the results with ANOVA. We performed two ANOVAs, on Attitude
(F(1,30) = 0.06, p = ns) and on purchase intention (Likert) (F(1,30) = 0.23, p = ns). We
conclude that neither hypothesis 3a nor hypothesis 3b is supported. Hypothesis 3b was also
tested using the dependent variable in which purchase intentions were measured
dichotomously, but both the Chi-Square test and the logistic regression failed to reject the null
hypothesis.
4.2.5. Testing hypotheses 4a and 4b
In order to test hypotheses 4a and 4b, we had to build the contrast between the
price-reduction-for-future-purchases condition and the absolute-price-reduction,
relative-reduction and gift conditions. We did this by recoding the variable condition so that the
price-reduction-for-future-purchases condition is coded with 1 while the absolute-price-reduction,
relative-price-reduction and gift conditions are coded with -0.33. After doing this we tested
the results with ANOVA. We performed two ANOVAs, on Attitude (F(1,37) = 0.75, p = ns)
25
hypothesis 4a nor hypothesis 4b is supported. Hypothesis 4b was also tested using the
dependent variable in which purchase intentions were measured dichotomously, but both the
Chi-Square test and the logistic regression failed to reject the null hypothesis.

Before we proceed to hypothesis testing, we computed the (unweighted) scale mean
for Attitude, by averaging the scores of the 4 items that constitute the scale. The reliability of
the scale is Cronbach’s Alpha = 0.949, hence we can consider the Attitude scale as reliable.

An ANOVA (F(3,63) = 5.25, p < 0.01) was performed on Attitude, confirming that the
framing of the incentive offered to customers to switch shopping channels influences the
attitude towards the retailer.
4.3.2. Testing hypothesis 1b
An ANOVA (F(3,63) = 5.24, p < 0.01) was performed on purchase intention (Likert),
confirming that the framing of the incentive offered to customers to switch shopping channels
influences the purchase intention. These results are supported by testing this hypothesis using
the depend variable measured dichotomously, as shown by the Chi-Square test (Chi-Square(3)
= 7.97, p < 0.05). Next, we test the hypothesis, by performing a logistic regression on the
dependent variable purchase intention, measured dichotomously. Similar to testing this
hypothesis in the first experimental setting, the independent variable is framing of monetary
incentives while gender, frequency of online purchases, impulsiveness and time pressure are
the control variables. In this case Impulsiveness was measured with four items (description in
appendix 1) with a Cronbach’s Alpha of 0.89. Time pressure was measured with three items
(description in appendix 1) with a Cronbach’s Alpha of 0.93.

Following the same procedure as for the first experimental setting, we use the
likelihood ration test to evaluate model fit. In the model that we tested, the model fit of the
proposed model is significantly better than the empty model, as shown by the Chi-Square(7) =
28.3, p < 0.001. This means that the predictor variables explain a significant amount of
variation in the dependent variable.

As we can see in the table above, the likelihood ratio tests show that impulsiveness,
time pressure and framing have a significant influence on channel switching, while gender
and frequency of online purchases do not significantly impact purchase intentions. Analyzing
the parameter estimates (table in appendix), we observe that impulsiveness positively
influences channel switching, while time pressure has a negative influence on channel
switching. We conclude that hypothesis 1b is supported.

In order to test hypotheses 3a and 3b, we had to build the contrast between the gift
condition and the absolute-price-reduction and relative-price-reduction conditions, in the

variable condition so that the gift condition is coded with 1 while both the
absolute-price-reduction and relative-price-absolute-price-reduction conditions are coded with -0.5. After doing this we
tested the results with ANOVA. We performed two ANOVAs, on Attitude (F(1,51) = 4.4, p <
0.05) and on purchase intention (Likert) (F(1,51) = 1.1, p > 0.1). We conclude that hypothesis
3a is supported, while hypothesis 3b is not supported. Hypothesis 3b was also tested using the
dependent variable in which purchase intentions were measured dichotomously, but both the
Chi-Square test and the logistic regression failed to reject the null hypothesis.

using the depend variable measured dichotomously, as shown by the Chi-Square test
(Chi-Square(1) = 7.22, p < 0.01). Furthermore, performing a logistic regression on the dichotomous
dependent variable, we obtain a Chi-Square(1) = 6.65, p < 0.01, consistent with hypothesis
4b.

5. Discussion
The aim of the current study was to identify how companies can convince customers
to switch shopping channels by offering them monetary incentives. Our study investigated
how customers respond to four equivalent monetary incentives with different framings, in the
context of right-channeling them. In an experiment, we presented participants with four
different framings of the monetary incentives: absolute-price-reduction,
relative-price-reduction, gift and price-reduction-for-future-purchases, and then measure the participants’
attitudes towards the retailer and the intention to switch channels, in the context of purchasing
a laptop (setting 1) and a touristic package (setting 2). Our results confirm that the framing of
30
the retailer and switching rate to the desired channel, but this holds only in the case of the
experimental setting where a touristic package was the focal product, whereas when the focal
product was a laptop, the effects of framing were not significant. This is an indication that, at
least in the case of services being the focal product, the mere framing of the incentive to
switch shopping channel can influence the cognitive judgments and decisions made by
consumers.
For both settings (laptop and touristic package), our results failed to show the
hypothesized difference between an absolute-price-reduction and a relative-price-reduction in
terms of attitude towards the retailer and switching rate to the desired channel. We fail to
confirm the findings of previous studies (DelVecchio et al., 2007; Krishna et al. 2002). Under
the assumption that customers, being faced with a price reduction, calculate the revised price
of the product or service, calculating the revised price resulting from an
absolute-price-reduction is easier than calculating the revised price resulting from a relative-price-absolute-price-reduction.
A possible explanation is that, given the fact that both focal products in our experiment were
relatively expensive, the participants naturally engaged into calculating the revised price in
both the absolute-price-reduction and the relative-price-reduction conditions. The “round”
prices that the focal products had in our experiment made it easier for participants to calculate
the revised price; hence the difference between the two conditions was reduced.
When we used a service as the focal product, a gift offered as incentive to customers to
switch shopping channels would lower the attitude towards the retailer in comparison with an
absolute-price-reduction and a relative-price-reduction, but would not significantly reduce the
switching rate to the desired channel. A possible explanation of this effect is that gifts offered
as incentives are perceived as suboptimal by the customer. With money they can purchase
31
choice, since the gift, although it has the same monetary value, has already been chosen by the
retailer, or the options to choose from are limited.
Furthermore, our results confirmed the hypothesized negative influence of the
price-reduction-for-future-purchases framing. This framing negatively influences the attitude
towards the retailer and the switching rate to the desired channel, in comparison with the other
framings used in our study, but again this effect holds only for services (i.e. the touristic
package experimental setting) and not for products (i.e. the laptop experimental setting). This
effect indicates that the time and effort involved with redeeming the
price-reduction-for-future-purchases is likely to have a negative effect of customer perceptions and reduce their
purchase intentions. As Folkes and Wheat (1995) suggest the temporal distance involved in
getting the discounts associated with the future purchases stimulate the customers to see the
present monetary value of such an incentive as lower, hence
price-reduction-for-future-purchases are likely to be viewed as less attractive than an immediately received incentives.
6. Managerial contributions
Our study contributes to the multichannel marketing literature by showing that it is
possible to persuade customers to change their shopping channel and by identifying what
companies can do in order to facilitate the customers’ migration to the channel preferred by
the company. Besides the scientific contributions, our research also has multiple managerial
contributions, as it provides a set of guidelines on how to persuade customers to buy from the
desired channel, in what context this is possible, and what are the expected success rates.
Firstly, the results of our research have implications for the resource management of the firm.
We show that a price reduction of 5% produces a 87% change in shopping channel in the case
32
communication managers. We identify four different framings of equivalent monetary
incentives, and we compare their effects on attitude towards the retailer and switching rate to
the desired shopping channel. The absolute-price-reduction framing seems to have the best
results. Thus, our research sheds light on the process of optimizing framing of the monetary
incentives offered to customers for switching to the shopping channel preferred by the firm.
The challenge for managers of multichannel retailers will be firstly to identify which shopping
channel is the most profitable for them. Once that is sorted out, our research provides these
managers with an indication of an expected success rate of convincing their customers of
switching to the preferred shopping channel and also a recommendation regarding what
framing they should use for the monetary incentives that they offer for right-channeling their
customers. Finally, our research offers determines the boundary conditions of the effect of
framing. Differences in the effect of framing the monetary incentives were found only in the
case when a service was used as the focal product. This suggests that in the case of goods, the
framing of the monetary incentives offered to convince the customer to switch shopping
channels is less important.
7. Limitations and Further Research
Several limitations influence the accuracy and validity of our study. Firstly, the
non-probabilistic nature of our study could have led to self-selection bias. The subjects of our
experiment were found on Facebook and no incentive was offered to them to participate or to
give reliable answers. A probabilistic sample and a more limited self-selection would have
been better. Secondly, quite many of the participants failed the manipulation check (54% of
the participants in the first experimental setting and 29% in the second setting). This is an
33
manipulations were based, or they did not understand the texts that they had to read. The fact
that the experiment was in English could have caused problems, because for the vast majority
of the participants English is not their native language. Thirdly, the sample sizes which
entered the statistical analyses (39 for the first setting and 67 for the second setting) are very
low given the fact that there were 4 experimental conditions. In this context, the study is
slightly underpowered, which may lead to type 2 errors.
Future research should address the limitations of our study. Furthermore, it would be
worthwhile to investigate the channel switching rate of other type of focal products, for
example products with a lower price. In addition, we only explored the context of online
shopping, but for many retailers, it could be the case that another shopping channel is deemed
as optimal. Finally, a cross-cultural study would shed light on the cultural aspects of the
