Aims & justification
◦ 1– Is MINM moderated by self
focus?
◦ 2 – is MINM mediated by self
focus?
◦ 3 – Generalisability of MINM
5

Method
◦ 33 participants, volunteer sample
◦ Independent design
◦ Randomly allocated into ‘sad condition’ and ‘neutral condition’.
◦ Self–focusing essay
◦ Buying task
◦ Manipulation check & debriefing


Results
T-tests show that sad condition
participants spent more than
neutral condition participants.
There was a larger effect in high
self-focus group against low
self-focus group.
7

Discussion
The MINM effect only occurs when self-focus is high
Relationship between sadness and spending mediated &
moderated by self-focus
Other possible interpretations of the data:
- mood repair
- reduced self value
8
• Relevance
- James (1890)
- Contradictory evidence from Capra, Lanier & Meer (2010) – positive
mood led to overbidding during an auction task
• Future research
- Test sadness and self-focused when an object is unobtainable
- Models in clinical depression, link to compulsive buying (Black et al 1998)

Aims & Justification
◦ To see whether people were more willing to pay more when
using a credit card (credit card premium).
◦ Investigate generalisability of Feinberg (1986)’s results.
◦ Investigate influence of knowing the market price and credit card
stimuli.

Specific Aims
 Investigate necessary conditions to support credit card premiums.
 Investigate whether consumers adjusting valuations from
anchoring points is a valid explanation.

Method
 Participants selected by an opportunity sample where randomly
assigned to one of four groups, credit card / cash condition and
letters & digits / type of card
 Invited to buy a dinner certificate
 Becker De-Groot ‘incentive –compatible’ procedure


General discussion
 Authors suggest that there is no evidence that exposure to credit
card logo increases willingness-to-pay
 Authors suggest that congruence is more important
 Authors suggest liquidity constraints (access to cash) does not
explain the credit card premium.
 Authors suggest that customers adjust their valuations from
different anchoring points in the cash/credit card conditions.
16

Relevance
 Has been looked at since 1970’s
 Used real money transactions therefore more generalisable
 High value goods as usually use credit card for this purpose
 Current issue - economic crisis

Misery is not Miserly…


Overall we consider this a
good study with good
relevance, but there was a
methodological flaw with the
self-focused essay.
Does have clinical implications
which are useful for real world
applications.
Always Leave Home Without
It…

In our opinion this paper is
overcomplicated and it
contradicts itself between the
first and second experiment.

However does introduce a
new methodology and so does
contribute to future research.
