Workshop - CSMN, University of Oslo
2Two Questions about Altruism
- Intrinsic motive for altruism
- Cognitive based on knowledge, thought or reason
- Affective based on moods, feelings or emotions
- Subject of much empirical and theoretical
research - Economics mostly inferred from behavior
- Psychology mostly studied through self-reports
- Extrinsic purpose of altruism
- Conditional altruism conditioned on moral norms
- Unconditional altruism not conditioned on any
norms, although often implicitly depends on
personal relationships
3 The sentiment or affection of the heart from
which any action proceeds may be considered
under two different aspects, or in two different
relations first, in relation to the cause which
excites it, or the motive which gives occasion to
it and secondly, in relation to the end which it
proposes, or the effect which it tends to
produce. Adam Smith, The Theory
of Moral Sentiments
4Goals of the current study
- Construct simple models of altruism and generate
behavioral predictions from those models - Employ a parallel experimental design to
discriminate behavior predicted by the alternate
theories - Collect data on short run (or transient) feelings
and relate to altruistic behavior first
economics experiment to do so - Formulate a theory of conditional altruism to
reconcile results inconsistent with theories of
unconditional altruism
5Unconditional Altruism
- Economic theories of unconditional altruism
- Pure altruism (Becker 1974)
- Preference for anothers material or psychic
well-being - Cognitive, unselfish concern for others
- Warm glow (Andreoni 1989, Harbaugh 1998)
- Good feeling from giving
- Selfish concern for ones own happiness
- Impure altruism (Andreoni 1989, 1990)
- Combination of pure altruism and warm glow
- Psychological literature on altruism
- Cognitive (Cialdini) Identification and merging
with others, so selfishly help others as one
would oneself - Affective (Batson) Selfless empathy with those
in need
6Behavioral Implications Crowding Out
- Crowding out
- Do increased contributions to a public good
(e.g., charity) by others reduce (or crowd out) a
donors own transfers? - Pure altruism
- Individual since the donor only cares about the
total benefit to a recipient, a one dollar
increase in other contributions will reduce his
voluntary donations by one dollar - Public policy public spending on public goods
will crowd out private spending dollar-for-dollar
(crowding out is complete) - Impure altruism
- Individual a one dollar increase in other
contributions will reduce the donors giving but
by less than one dollar, because he takes
pleasure in giving per se - Public policy one dollar in public spending will
reduce private donations by less than one dollar
(crowding out is incomplete)
7Evidence on Crowding Out
- Crowding out appears to be incomplete
- Field studies of actual charitable giving (e.g.,
Kingma 1989, Payne 1998) - Public goods experiments (Andreoni 1993, Palfrey
and Prisbey 1996, 1997) subjects voluntarily
contribute to a fund shared by all - Limitations of these studies
- Imperfect information about public spending
- Selfish concern for status or prestige
- Results from public goods experiments potentially
confounded by subject confusion, expectations or
strategic considerations
8Affective Motivation
- Evidence
- Mere possibility of recipients expressing
emotions about level of donor transfers is
sufficient to increase transfers (Ellingsen and
Johannesson, 2008, Xiao and Houser, 2007) - Neural evidence is consistent with both pure
altruism and warm glow, i.e., impure altruism
(Harbaugh et al., 2007) - Theory
- Few studies present formal models linked to
empirical measures of happiness, or subjective
well-being as it is called in the psychology
literature (Graham and Oswald, 2008, McBride,
2008)
9Description ofBasic Experimental Design
- Dictator Game (or Dictator Experiment)
- One subject, called the dictator, is endowed
with a fixed sum of money - The dictator may share his/her endowment with an
anonymous counterpart, called the recipient,
who is in another room - Recipients have no recourse and must simply
accept whatever dictators give (even nothing),
eliminating strategic concerns on the part of
dictators
10- Simple design minimizes subject confusion
potentially present in more complex experiments,
e.g., public goods experiments - All subjects complete a questionnaire asking
about mood just before and just after the
allocation decision - Double blind procedures no one, including the
experimenter, can associate decisions or
responses with specific subjects, minimizing
self-interested reasons for giving (e.g., status,
prestige) and for misrepresenting true mood
(e.g., social desirability)
11- Previous Dictator Findings
- Tax experiment
- (Bolton and Katok 1998, Eckel, Grossman and
Johnston 2005) - Two treatments in between subjects design with
differing endowments of dictators and recipients - Treatment Dictator Recipient
- Tax 18/2 18 2
- Tax 15/5 15 5
- Tax experiment because it is as if the dictator
were subject to an involuntary tax that is given
to the recipient - Every subject participates in only one treatment
as dictator - After decisions, one of the two subjects in a
pair is randomly chosen to be dictator for actual
allocation (strategy method) - Predictions of the model are summarized in
Proposition 1
12- Proposition 1
- Under unconditional altruism, crowding out in the
Tax experiment is partial or complete - Pure altruism Dictators care only about the
final distribution and not whether their gifts
are voluntary or involuntary, thus, crowding out
is complete - The more heavily taxed dictators give a full 3
less in the 15/5 treatment compared to the 18/2
treatment - Warm-glow Dictators value the gift itself, and
crowding out is partial (i.e., incomplete) - Dictators give less in the 15/5 treatment than
in the 18/2 treatment but this difference is less
than 3 - Impure altruism Crowding out is incomplete and
intermediate to pure altruism and warm glow - Pure altruism motivates a larger reduction than
with warm glow alone, but warm glow prevents this
from being complete
13Results and Limitations
- Results
- Dictators give less in the 15/15 treatment than
the 18/2 treatment - This difference is less than 3, indicative of
incomplete crowding out - Limitations of design
- This design does not allow one to differentiate
warm glow and impure altruism incomplete
crowding out is consistent with both hypotheses - Subjects roles having subjects play both roles
differs from much real world giving and might
affect the level of transfers - Strategy method some studies suggest decisions
differ when each decision is actually paid out,
especially when social preferences are at issue
14New Experiments
- Subjects are always in only one role, dictator or
recipient - All decisions are actually paid
- Dictators are always student subjects with 10
endowments - Treatments differ with respect to recipient
identity, recipient endowments or possible
transfers - Subsidy Experiment
- Recipients are all fellow students whose initial
endowments vary across treatments - All endowments are common knowledge
- Two treatments
- Standard treatment Recipients are unendowed
- Subsidy treatment Recipients are endowed with 4
(like subsidizing dictator gifts to recipients)
15Predictions for Subsidy Experiment
- Proposition 2
- With unconditional altruism, crowding out in the
Subsidy experiment is partial or zero - Warm glow Crowding out is zero, since transfers
are motivated solely by the act of giving - Dictator transfers are the same in the Standard
and Subsidy treatments - Pure altruism Crowding out occurs, since
dictators care about the recipients total
allocation and, therefore, are lower in the
Subsidy treatment than in the Standard treatment - Crowding out, however, is incomplete the
recipients endowment reduces the marginal
benefit of giving to him - Impure altruism Crowding out is partial but
smaller than in the case of pure altruism
16- Charity experiment
- Recipients are always unendowed
- Treatments differ with respect to whether
recipients are students or charitable
organizations - Two treatments
- Charity treatment Recipients are one of two
obscure charities, Childreach or Children
International, one of which each dictator must
choose if he/she gives anything - Standard treatment Recipients are fellow
students whom subjects have seen at start of
experiment
17- Eckel and Grossman (1996) found donations to Red
Cross significantly greater than those to
anonymous students and conclude - Familiarity Hypothesis
- Donors are more generous toward recipients about
whom they have more information, ceteris paribus. - The current experiment reverses the information
conditions such that average gifts to the
relatively unknown charities in the Charity
treatment should be less than those to known
students in the Standard treatment
18- Preference-based crowding out is
- ambiguous in Charity experiment
- If experimental frame takes, there is no
obvious preference-based reason for dictator
transfers to differ across treatments - If dictators interject own assumptions about the
recipients endowments external to experiment,
however, transfers might be lower in Standard
treatment than Charity treatment (although this
difference is also consistent with an alternate
hypothesis discussed later)
19- Matching grant charity manipulation
- On about one-half of forms for subjects in the
Charity treatment, a statement is added that
indicates that donating 1 to Childreach will
make available an additional 3 through a
matching grant program. - In other words, the benefit to the recipient for
every dollar given, or matching grant multiplier,
equals 4.
20- Predictions regarding matching grant
- If warm glow is the sole motive, there should be
no difference in the percentage of subjects
choosing Childreach over Children International
because of a matching grant. - Any shift, however, toward Childreach in the
version with the matching grant indicates some
concern for the well-being of recipients,
consistent with pure or impure altruism.
21- Proposition 3
- An unconditionally altruistic donors gift to a
charity is nondecreasing in that charitys
matching grant multiplier. Specifically, the
effect on giving of a matching grant multiplier
of 4 is - Warm glow zero
- Pure altruism positive
- Impure altruism positive but less than with pure
altruism - Conclusion A matching grant increases giving
with pure or impure altruism but has no effect on
giving if altruism is motivated solely by warm
glow.
22Affective Evidence onWarm-glow
- Measures of changes in mood
- Identify self-reported changes in mood, or short
run affect (SRA), of dictators by comparing
measure of mood just after the allocation
decision with mood just before decision (SRAD). - Compare the mood changes of more generous
dictators in each treatment with those of two
other groups - Less generous dictators in the corresponding
treatment (Standard, Subsidy or Charity) - Control treatment Dictators are paired with
unendowed student recipients but are prevented
from transferring any of their endowment the
endowments and procedures are common knowledge.
23Summary of Experimental Design
- Four treatments differ as follows
- Standard Recipients are unendowed students 47
pairs of dictators and recipients - Subsidy Recipients are students endowed with 4
58 pairs of dictators and recipients - Charity Recipients are one of two unendowed
charitable organizations 47 dictators plus 24
from pilot study sometimes used - Control Recipients are unendowed students and
they remain so dictators have no opportunity to
give any of their 10 endowment to recipients 45
pairs of dictators and recipients
24Experimental Procedures
- Recruitment subjects were required to
participate in an experiment to satisfy course
requirement addresses possible self-selection
bias and generates more variance - Show-up fee of 5 plus salient earnings
- After being paid, 96 indicated they would be
willing to participate again in economics
experiment - Initially show up to common room and then
dictators and recipients randomly assigned to
separate rooms - Double blind procedures no one can associate
decisions with a specific subject, including the
experimenter - Short run affect score (SRA) derived from
responses on nine-point scales to good mood-bad
mood and depressed-elated item change in SRA
(SRAD) equals SRA after the allocation minus SRA
before the allocation decision (or announcement
of payment in Charity treatment)
25- Sequence of steps
- All subjects complete a questionnaire that
includes short run affect questions. - Each dictator then chooses how many of their ten
1 bills to pass along to a recipient. - Everyone completes another questionnaire that
repeats the short run affect questions. - All forms and gifts are put in a single packet.
- Later follow-up questions ask anonymous
demographic questions that cannot be associated
with the earlier decisions. - Charity treatment is the same except
- Dictators choose to give to one of two charities
or to neither from brief descriptions. - Follow-up questions also ask whether they had
previously heard of these charities.
26Notes on Deviations from Benchmark Cases
- Subsidy A few dictators in these sessions did
not properly process the 4 gift based on the
post-experimental questionnaire, so we also
consider a Subsidy Subset that excludes six
confused subjects. - Charity The four basic Charity sessions used
same procedures as other treatments two Charity
pilot sessions differed (e.g., they excluded
short run affect measures), but allocations in
the pilots do not differ significantly from basic
charity sessions, so they are also reported in
those instances as Pooled Charity.
27Results of Allocation Decisions
- Gifts are most generous in the Charity treatment,
followed by Standard and then Subsidy. - Modal gifts of Givers create equal splits in all
cases save Charity Standard 5, Subsidy 3 (also
in earlier Tax 15/5 5 and Tax 18/2 8, not shown
here).
28- Formally test crowding out using three parametric
and nonparametric tests of differences in giving
(differences in means, Mann-Whitney and
Kolmogorov-Smirnov) - According to most tests, crowding out occurs but
is incomplete (Table 4) - Giving is significantly greater in the Charity
treatment than in the Standard treatment,
contrary to the Familiarity Hypothesis
29- The results of the Charity experiment cannot be
attributed to differences in the familiarity of
subjects with recipients, since mean gifts do not
differ based on level of familiarity
30Summary of Matching Grant Results(Table 6)
- Results on choice of charity
- The proportion of dictators choosing the matching
grant charity counts against warm glow and for
pure or impure altruism. - In the normal version in which the grant is not
mentioned, subjects choose Childreach and
Children International in about the same
proportion, but Childreach with the matching
grant is chosen significantly more often than
Childreach without the grant or than Children
International. - Results on level of giving
- Evidence on the level of giving, however, is
inconsistent with pure or impure altruism. - Dictators should give more to Childreach with the
matching grant, but they do not indeed they give
less significantly so in one case.
31Results on Affective Motivation
- Sample in each treatment is bifurcated into
dictators whose gifts are at or above that of the
median Giver, or High gifts, and those below
this, or Low gifts (Table 5) - Compare changes in mood (SRAD)
- Standard and Subsidy treatments
- Those who give less are significantly happier
(have a bigger boost in SRA after allocation
decisions) than those who give more - Charity treatment
- Dictators who give more are somewhat happier,
although this is marginally significant - Control
- Dictators in Control are significantly happier
after being told they will keep all than before
being told - Relative to Control, dictators are less happier
who give more in the Subsidy treatment and less
in the Charity treatment (Standard not
significant)
32Regressions Results on SRAD
- OLS regression of SRAD on Gift
- SRAD a ßGift e
- These regressions substantiate results with means
- Weak evidence of warm glow in the Charity
treatment for the normal case but not for the
matching grant case
33Warm Glow or Hot Sting?
34Conclusions about Warm Glow
- Reject warm glow in the Standard and Subsidy
treatments at statistically significant levels - People have mixed feelings generosity has an
unfavorable effect on short run feelings when
ones recipients are students, but a possibly
favorable one when they are charities - These effects are not due to self-selection, as
evidenced by comparison to the Control Chosen
levels of giving in the other treatments can at
best match the SRAD in the Control treatment
35Conclusions aboutUnconditional Altruism
- The results on feelings add to the previously
noted findings on allocation decisions that often
conflict with warm glow, pure altruism and/or
impure altruism - Collectively, there are numerous inconsistencies
in the evidence on allocation decisions and
feelings with the various theories of
unconditional altruism
36Conditional Altruism
- Theory of conditional altruism is an alternate
approach that reconciles evidence of allocation
decisions and feelings inconsistent with theories
of unconditional altruism - Introduces moral norms as in more general social
preference literature, which includes
considerations of fairness, need, efficiency,
reciprocity, etc. - Moral norms depend on context (e.g., Bicchieri,
2006) here employ context dependent distributive
norms - Happiness is also related to different norms that
depend on the context (e.g., Railton, 2006) here
focus on short run happiness
37Model of Conditional Altruism
- Conditional altruism incorporates a simple, but
important, consideration in decisions about
giving a condition (f) that a donor believes to
be the right gift to the recipient - To be more exact, the condition is the right
benefit that the gift should produce (the two are
the same in this study, except in the case of the
matching grant charity where the benefit
generated is four times the gift) - Utility (preferences) are a function of ones own
allocation (material utility), conditional
altruism that relates the gifts benefit to f
(like inequity aversion) and a term that depends
solely on giving (like warm glow)
38Conditional Altruism Term
- xj is the gift
- fj is the condition
- f() is the conditional altruism preference term
of the utility function
39Determination of the Condition (f)
- In the context of this study, the two most
salient distributive standards are - Equity
- In contextually simple studies like this one,
equity corresponds to equal splits - Equity applies in Standard, Tax and Subsidy
treatments with student cohorts - Need
- This principle calls for satisfaction of basic
needs and requires a larger transfer than equity,
when basic needs are not satisfied with equal
splits - Need applies in Charity treatment with
organizations that serve needy recipients
40- Stylized facts from numerous previous studies
- Dictators who are stakeholders exhibit, on
average, a self-centered bias in their
allocations and in their beliefs about right
allocations in comparison to impartial third
party spectators who have no stakes - Nevertheless, a majority of stakeholder dictators
who give anything at all (the Givers) allocate
the same impartial amount chosen by spectators
this permits one to infer the impartial f from
the modal decisions of stakeholders - The formal analysis is qualitatively the same
using the impartial standard or the biased belief
for f, but acknowledging possible differences
between impartial gifts and biased beliefs help
explain certain patterns in the results later
41Predictions of Conditional Altruism
- Proposition 4
- Assuming conditional altruism, crowding out in
the Tax experiment is partial - This is similar to the case of impure altruism
- Proposition 5
- With conditional altruism, crowding out in the
Subsidy experiment is partial, specifically, less
than one-half - Together, these propositions are more specific
than unconditional altruism and also imply that
crowding out in the Tax experiment is less than
one-half that in the Subsidy experiment
42- Proposition 6
- A conditionally altruistic donors gift changes
in direct relationship to, but by less than, any
change in the amount the donor believes to be
right, i.e., if the condition rises by 1, the
donor will increase his gift but by less than 1 - Comparing the Charity and Standard treatments,
this means dictator gifts will be greater in the
former versus the latter treatment, but by less
than the difference in f - This would be true, even if preferences did not
depend on the size of the gift per se
43- Proposition 7
- Under conditional altruism, the effect of a
matching grant program on gifts to that program
is ambiguous. A sufficient condition for the
optimal gift with matching grant to be lower,
however, is that the optimal gift in the normal
case without the matching grant be greater than
or equal to f divided by the matching grant
multiplier (4) - Example To take the extreme case, if f is the
maximum of 10, and giving in the normal version
is no less than 2.50 (10/4), giving in the
matching grant version will be lower than in the
normal version
44Reconciliation of Conditional Altruism
withActual Allocation Decisions
- Modal gifts of Givers are consistent with
hypotheses about motives in each respective
treatment 5 in Standard, 3 in Subsidy, 5 in
Tax 15/5, 8 in Tax 18/2 create equal splits of
total modal transfer in Charity implies a f of
10 - Partial crowding out in Tax and Subsidy
treatments is consistent with Propositions 4 and
5 (and impure altruism), but not with pure
altruism or warm glow - Relative magnitudes of crowding out in Tax versus
Subsidy experiments are consistent with
conditional altruism, but not predicted by any
theory of unconditional altruism crowding out is
48 in the Tax experiment and 18 (less than
one-half) in the Subsidy experiment - Gifts in Charity treatment are larger than in
Standard treatment, but by less than 5
difference in ?
45Reconciliation with Matching Grant Results
- Choice of charity
- Increased proportion of dictators choosing
matching grant charity is consistent with
conditional altruism, and also pure or impure
altruism, but not warm glow - Level of giving
- Pattern of mean gifts in the Charity experiment
is consistent with conditional altruism but not
any theory of unconditional altruism - Mean gifts in Childreach (match) version are less
than Childreach (normal) and Children
International (when given the choice of
Childreach with match).
46- Effects of matching grants on expected
revenues of charities, i.e., donations averaged
across the entire pool of donors - Average Childreach donations rise from 2.57 to
3.26 average gift per donor falls from 7.20 to
5.43 but percentage of potential donors
Childreach captures rises from 36 to 60 - Average Children International donations fall
from 2.74 to 1.66 average gift per donor rises
from 5.82 to 8.29 but capture rate falls from
47 to 20 - Across all dictators, the matching grant reduces
average giving from 5.31 to 4.91 (insignificant
difference) - Prisoners dilemma Charity offering the matching
grant benefits while aggregate charitable
donations do not rise and perhaps fall?
47Reasons for Giving
- In post-experimental questionnaires, about
two-thirds of high gifts were explained in terms
of equity/equality in the Standard and Subsidy
sessions and in terms of other peoples needs in
the Charity sessions - Low gifts were often explained by appeal to the
dictators own needs - Own needs were not borne out when analyzed based
on the reported material well-being of generous
vs. selfish dictators
48Reconciliation of Conditional Altruism with
Results on Affective Motivation
- Conditional altruism conjecture is that better
feelings are associated with gifts that comply
with (beliefs about) the relevant social norm, f. - Average dictator gifts will lie somewhere between
impartial value and more selfish allocation. - In ascending order, f is lowest in the Subsidy
treatment (with an impartial f of 3), then
Standard (impartial 5), Charity with matching
grant (infer from average gift of 5.43 that
impartial value is higher than 5), and Charity
without the matching grant (10). - Linear regression of SRAD on gifts shows
increasing slope in same order (dark lines in
Figure 2). - Conclusion Better feelings are associated with
low gifts when f is low and high gifts when f is
high.
49- Subsidy (a), Standard (b), matching version
Charity (c) and normal version Charity (d)
treatments.
50Conjectures and Suggestive Evidence forFurther
Research on Feelings and Moral Norms
- Short run feelings are associated with social
norm compliance as represented by the conditional
altruism term - Retain the term that relates to giving per se
(like warm glow) to explain incomplete crowding
out, but not assumed to be motivated by short run
affect - Long run happiness one explanation for
incomplete crowding out is relationship of giving
to long-run feelings giving is like an
investment that contributes to long-run happiness
(Konow and Earley, 2008) - Nonlinear regression of SRAD on gift (adding
squared gift term to right hand side) produces
lighter, mostly concave lines
51- Subsidy treatment (Figure 2A)
- Nonlinear regression of SRAD on gift produces
lighter, concave line for Subsidy case.
Self-serving bias suggests average f slightly
less than 3. - In other treatments, the salient values for f
differ by a wider margin. Other studies suggest
these beliefs cluster mostly around two values
the impartial f and very self-serving amounts
(0-1). Thus, the observations are partitioned
in the other treatments (by vertical lines).
52- Standard treatment (Figure 2B)
- Two clusters around 0 and 5 two outliers at
10. - Of group giving less than 3, 64 of available
responses explained based on Own Need and none
based on Equity. - Of the group giving 3 to 7, 89 referred to
fairness and none to need (no explanations
available for two 10 gifts).
53- Charity treatment with matching grant (Figure 2C)
- Concave SRAD in gifts greater than 1 maximized
at 6.25. - Anecdotal evidence on concern for efficiency 86
of dictators who gave to Childreach with the
matching grant pointed to the increased benefit
as a reason for choosing that charity.
54- Charity treatment without matching grant (Figure
2D) - Concave SRAD in gift greater than 1 maximized at
14.25 (partially explains two dictators who not
only gave their 10 endowment but also dipped
into their show up fees?).
55Conclusions
- This study provides evidence on altruism using a
design that minimizes confounding effects - Partial crowding out in the various experiments
contradicts pure altruism and warm glow alone - Unconditional altruism, including impure
altruism, is also refuted by additional evidence
on short run affect and matching grant giving - Charity experiment indicates greater generosity
to charities cannot be attributed primarily to
greater familiarity - Mixed feelings greater generosity is associated
with worse feelings in the Standard and Subsidy
treatments, and perhaps with better feelings only
in the Charity treatment - Conditional altruism offers a means to reconcile
the otherwise contradictory results on both
allocation decisions and affective motivation
across the various experiments
