A COMPARISON OF THE EFFECTS OF ONLINE SOCIAL
INTERACTIONS ON THE CONSUMERS DECISION
MOTIVATION TO STUDY
•
Psychological background
•
Customers decision making process is not optimal
•
Gap in existing literature
Research questions:
•
“To what extent do consumers rely on observational learning (OL) cues in an online
decision making process for annuities, compared to regular durable goods?”
•
“To what extent do consumers rely on electronic word of mouth (eWOM) in an online
decision making process for annuities, compared to regular durable goods?”
CONCEPTUAL
MODEL
• SOCIAL INTERACTIONS
• OBSERVATIONAL LEARNING
• ELECTRONIC WORD OF MOUTH
MAIN FINDINGS
•
The analysis shows that the two product types do differ on its characteristics.
•
According to the literature this also leads to different sequence of steps in the
decision making processes. In addition, persuasion will be determined by different
kinds of information.
•
The main effects of social interaction slightly differs for annuities compared to
regular durable goods.
•
However, for both product types the moderating effects turned out to be only
marginally significant and only for a couple of social interaction valences.
•
Overall: Useful insights for managers and consumers on the effects of online social

Regular durable good
(Digital camera)
Annuity
(Health insurance)
Payment is made once Payments are made over time within the accumulation phase
Relatively short term oriented (< 5 years)
Long term oriented Price is determined, and value is only
changing due to deprecation
Price is fluctuating due to inflation and value depends on the accumulation phase The moment of delivery of the product is
the same as the moment of buying
The moment of delivery (i.e. annuitization phase) of the product is delayed to a later
moment in time

RESULTS – MAIN EFFECTS
OBSERVATIONAL LEARNING
•
Positive OL has positive influence
•
Negative OL has negative influence
•
No OL also has a negative influence
ELECTRONIC WORD OF MOUTH
•
Positive eWOM has a positive influence
•
Negative eWOM has a negative
influence
•
Neutral eWOM has a positive influence
•
No eWOM has a negative influence
• Combining the models (predefined segmentation)• Covariates: Education level and Experience • Checking Model fit and validity
RESULTS – MAIN EFFECTS: COMPARISON
12 • Comparison between the two product types:
• Electronic word of mouth is ranked first for both product types, but the relative importance is higher in the digital camera setting.
• Observational learning is ranked second for both product types, but the relative importance is higher in the digital camera setting.
RESULTS – INTERACTION EFFECTS
• The model without interaction effect will make better prediction of the preferences of the respondents than a model with an interaction between OL and eWOM valence.
• However, to check the hypotheses according to this interaction it was necessary to include the interaction effects.
• Only three moderating effect are significant, and only on a 0.10 significance level.
Supported
• “Positive OL has a weaker effect on product preference when displayed with positive eWOM.” • “Positive OL has a weaker effect on product preference when displayed with negative eWOM.”
Rejected

DISCUSSION
• THEORETICAL IMPLICATIONS
• MANAGERIAL IMPLICATIONS
• LIMITATIONS
THEORETICAL IMPLICATIONS (I)
16
•
The relative attribute importance of e-WOM for a digital camera is even higher than
for a health insurance.
• The reason for this can be found in the decision making process where the need to make a more well considerate decision for a health insurance is more important than for a digital camera. This can explain the relatively more equally divided importance across all the
different attributes.
• Another explanation can be, that customers of annuities are more likely to choose to follow a more credible source of information (OL) instead of information with the highest
diagnosticity (eWOM).
•
No OL cue seems to be less preferred than negative OL
• A possible reason for this remarkable finding can be that people do not trust an OL signal
that only indicates “Unknown”, and therefore prefer a product with a negative OL cue
THEORETICAL IMPLICATIONS (II)
•
The impact of negative eWOM for health insurances indeed turned out to have a
bigger impact than positive eWOM. However, for digital cameras this was not the
case, since the magnitude of negative signals is smaller, compared to positive signals.
• A possible reason for this can be that digital cameras are not associated with a high level
of risk. And therefore the effect of negative reviews will be weaker.
•
It should be kept in mind that the findings according to the interaction effects did
only become significant at a ten per cent significance level. Moreover, the impact of
the interaction effects within this research are rather small.
• Therefore, one should be careful with the interpretation of this interaction effect.
PRACTICAL IMPLICATIONS AND LIMITATIONS
18
•
Managers – I would recommend managers to experiment with OL cues on their own
webpage or in other online settings.
• Since the positive effect of positive OL are relatively larger compared to negative OL. The possible gains turned out to be larger than the possible losses.
•
Managers – Be careful with presentation of eWOM.
• The relative high importance is also the result of the large downside of eWOM. Negative eWOM can hurt the preference for your products significantly.
• “The negative impact of negative reviews comes quickly and goes slowly” (Tirunillai & Tellis, 2012).
•
Limitations: number-of-level effect, number of respondents.
