Title: James Konow


1
Mixed FeelingsTheories and Evidence of Warm
Glow and Altruism
  • James Konow
  • presentation to
  • The Nature and Development of Moral Norms
    Workshop
  • CSMN, University of Oslo

2
Two 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
4
Goals 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

5
Unconditional 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

6
Behavioral 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)

7
Evidence 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

8
Affective 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)

Description 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

13
Results 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

14
New 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)

15
Predictions 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.

22
Affective 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.

23
Summary 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

24
Experimental 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.

26
Notes 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.

27
Results 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

30
Summary 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.

31
Results 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)

32
Regressions 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

33
Warm Glow or Hot Sting?
34
Conclusions 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

35
Conclusions 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

36
Conditional 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

37
Model 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)

38
Conditional Altruism Term
  • xj is the gift
  • fj is the condition
  • f() is the conditional altruism preference term
    of the utility function

39
Determination 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

41
Predictions 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

44
Reconciliation 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 ?

45
Reconciliation 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?

47
Reasons 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

48
Reconciliation 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.

50
Conjectures 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).

  • 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?).

Conclusions
  • 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
