Abstract: Although many studies have documented the presence of discrimination, there is very little research identifying the sources of discrimination. To better understand the sources of discrimination, we introduce a novel allocation game that aims to identify two possible sources of religious discrimination: taste-based and statistical. We implement lab-in-the-field experiments in two cities (Chandigarh and New Delhi) among 183 childcare workers (known as Anganwadi workers) in India. We do not find evidence of either taste-based discrimination or statistical discrimination among these caregivers, and our results indicate that workers in our sample are primarily motivated by welfare based criteria in making their allocation decisions; religious identities do not influence choices of our subjects.

1. Introduction
Discrimination has a long-standing history in society and has manifested itself through a
myriad of identities such as religion, race, caste, gender, and wealth.1 Social identities can
influence choices and economic activities crucially (Akerlof and Kranton 2010; Gangadharan
et al. forthcoming), and sustained discrimination based on identity often leads to violent
conflicts and imposes huge economic costs on society. Recent civil wars such as those in
Syria, Iraq, Central African Republic, and Sri Lanka were all fought along sectarian lines.
Although there exist theoretical foundations characterizing the sources of
discrimination—taste-based and statistical—there is relatively little empirical work that
focuses on identifying these different sources of discrimination. Taste-based discrimination is
a result of intrinsic preferences for a particular group or observable characteristic such as
religion, caste, color, or gender, and typically practiced towards the minority group (Becker
1971). Statistical discrimination on the other hand occurs where identities such as race, caste,
or gender serve as a proxy for other less easily observable characteristics such as ability,
productivity, and delinquency (see Arrow 1972; Phelps 1972).
Traditionally, cross-sectional regressions have been used to identify discriminatory
behavior. These regressions control for observable characteristics such as education, parental
income, age, location, and other socioeconomic factors, and additionally include an indicator
for identity such as being Black in the USA, or being a woman, or belonging to a lower caste
in India (see Altonji and Blank 1999 for a review); a significant coefficient on the identity
variable is used to indicate the presence of discrimination. The drawback of such a regression
is that identity could also serve as a proxy for unobserved characteristics (such as risk
preference, competition, social preference, productivity, ability) and consequently suffers 1 See, for example, Hoff and Pandey (2004), List (2004), Hanna and Linden (2012), Bertrand and Mullainathan (2004), and Banerjee et al.
(2009).

from omitted variables bias. These regression-based approaches neither measure market
discrimination nor disentangle the relative importance of animus versus statistical
discrimination (Guryan and Charles, 2013). The resumé audit methodology, often used in
studying discrimination in labor and housing markets (Anderson et al. 2012; Banerjee et al.
2009; Bertrand and Mullainathan 2004; Siddique 2009) is an improvement over controlling
for observables. Here, fictitious resumés are sent out for the same job with identical
qualifications but differing in characteristics such as gender, ethnicity, and race. These
studies capture how the response rate from the supply-side depends upon applicant
characteristics and can often unearth evidence of taste-based discrimination. More recently,
the resume audit methodology has also been used to comment on statistical discrimination
(see Kaas and Manger 2012).
Since laboratory experiments facilitate greater control over more difficult to observe
information, psychologists, and more recently, economists, have used them to elicit
discriminatory behavior. Laboratory experiments in psychology, which are almost
exclusively based on hypothetical incentives for choices, typically find a substantial in-group
bias and distinct favoritism towards groups designated as superior, or groups sharing the
same attitude/preferences as the decision-maker (Vaughn, Tajfel and Williams (1981), Billig
and Tajfel (1973) , Diehl (1988), Devine (1989), Turner and Brown (1978), Klein and Azzazi
(2001). This experimental literature also indicates that subtle cues can influence how people
process information where implicit associations seem to be prevalent and powerful. In
contrast to the psychology experiments, economics experiments on discrimination primarily
have monetary incentives for choice consequences. Some of the early economic experiments
find that subjects with randomly assigned and laboratory created status groups behave
differently compared to those without such status (Ball, Eckel, Grossman & Zame (2001),
Ball and Eckel (1996), Fershtman and Gneezy 2001). However, Lane (2015) in a recent
3
review and meta analysis comprising 77 experimental studies, points out that despite an
increase in the number of studies that examine discrimination using lab experiments, results
indicate only a moderate tendency towards out-group discrimination. In fact he notes that the
majority of results are found to be null results across the literature. Lane further clarifies that
the strength of discrimination against out-group members, if present, depends crucially on the
group identity being used in the experiments – it is stronger when identity is artificially
induced in the laboratory as compared to cases where subjects are divided by existing
ethnicity or nationality dimensions. Additionally, Berge et al. (2015), and Habyarimana et al.
(2007) suggest that in their lab-in-the-field settings, a lack of discriminatory behavior along
ethnic lines can stem from mechanisms different from that due to commonly attributed social
biases.
However, in all these experiments there are very few experiments that attempt to
distinguish between statistical and taste-based sources of discrimination by design (Lane
2015). Our focus is to contribute to this growing literature by designing an experiment that
attempts to separate out statistical discrimination from taste based discrimination in the
context of religious majority-minority groups in India. Islam is the second-largest religion in
Hindu-majority India, making up 14.9% of the country's population with about 180 million
adherents (2011 census). Majority and minority religious groups have been shown to play
important roles in economic choices in the Indian sub-continent (Gupta et al. 2016) and hence
studying discrimination along religious lines remains important for India. In this paper we
specifically test for discrimination against Muslim children by Hindu childcare workers (also
known as Anganwadi workers). Anganwadi workers in India are in an important position to
influence health and learning outcomes for children under six years of age. Hence evaluating
the presence, and sources of discrimination has important policy implications for over 3
million pre-school age children in India. In this context, we seek to separate out
4
discrimination that arises from preferences for religion only (taste-based discrimination) from
discrimination that comes from preferences for an unobserved characteristic for which
religion only serves as a proxy (statistical discrimination). We design a novel allocation game
where each Anganwadi worker decides how to allocate their endowments between mothers
of two randomly chosen children under three different information treatments. Findings from
choices under the three treatments provide no evidence of taste-based discrimination or
statistical discrimination among the child caregivers. We follow up with a complementary set
of experimental games to find that Anganwadi workers’ sharing decisions are instead
influenced by the poverty level and welfare of the recipients.
Our paper contributes to the discrimination literature in important ways. First, we
address Lane’s (2015) concern about the absence of experiments distinguishing the two types
of discrimination. We specifically design an experiment to identify and distinguish between
taste-based and statistical sources of religious discrimination. Second, we implement our
experiment among actual caregivers in the public health sector in India allowing us to
provide greater external validity, in contrast to typical framed experiments run among student
subjects.2 Third, we introduce a new allocation game to study discrimination where the cost
to the allocator is fixed, allowing us to completely control over selfish payoff maximizing
choices (in contrast to existing allocation games used by Fershtman and Gneezy 2001; List
2004). The game allows us to focus exclusively on altruistic preferences (or the lack of them)
towards different groups where the allocations provide a direct measure of any existing
preference bias. Fourth, common sense view suggests that childcare workers are not solely
motivated by financial incentives. We examine that by comparing their decisions in
incentivized and non-incentivized contexts. One of the limitations of the experiment is that it
2 Framed allocation games involving student subjects have allowed researchers to elicit choices and decisions under very different
environments such as health care, organ donation, charity, etc. (Kass et al. 2013; Leonard et al. 2013).

cannot distinguish between the various sources of statistical-based discrimination, which can
result over time from taste-based discrimination initially (Neilson and Ying, 2016).
Section 2 provides an overview of the context. Section 3 describes the experiment and
provides an analytical sketch of worker behavior. Section 4 discusses the results and
concluding remarks follow in Section 5.
2. Scope of Religious Discrimination
Health and nutrition outcomes matter not only for lowering child mortality but it is well
documented that poor nutrition under 5 years is strongly related to adult height and affects
completed grades of schooling, grade progression, test scores, and adult income (Behrman et
al. 2009; Maluccio et al. 2009; Mani 2012; Stein et al. 2003, 2008; Victora et al. 2008). ICDS
is the largest Early Childhood Development (ECD) program in the world, encompassing 1.3
million day care centers where child caregivers (Anganwadi workers) are responsible for
improving children’s nutritional status as well as pre-school readiness in India. Consequently,
Anganwadi workers in India are in an important position to influence health and learning
outcomes for children under six years of age.
These workers are responsible for distributing the government-funded mid-day meals aimed
towards improving nutrition among children. The workers can improve child health through
two main channels: first, through the distribution of mid-day meals and second, through
nutrition counselling to mothers. Both these tasks involve time and effort on which the
Anganwadi worker is constrained. A World Bank report by Gragnolati et al. (2005) found
both to be limited, with children not getting adequate nutrition in centers and almost no
effective communication between workers and mothers. Singh (2015) provides further
evidence on the leakages and inefficiencies in the ICDS program in India. In this paper, we
focus on constraints on monetary resources, and in particular evaluate how workers allocate
6
their fixed monetary resources between children of two different religions (Hindu and
Muslim).
In a seminal paper, Bhalotra et al. (2010) document that Muslim children in India face
significantly lower mortality risks in India as compared to Hindu children, despite being from
more socio-economically disadvantaged backgrounds and receiving less antenatal care.
However, Brainerd and Menon (2015) find that a corresponding Muslim advantage in health
outcomes exists only during infancy. Children from Hindu households become significantly
taller and heavier than Muslim children between the ages of 1 and 5 years across the Indian
subcontinent. The reversal of health fortunes that the authors find does not go away despite
controlling for maternal health, education, age at marriage, disease environment, birth order,
sanitation, prenatal care, breastfeeding, or household assets. Thus, even though demand-side
factors cannot explain the Hindu advantage post infancy, supply-side factors such as the
quantity and quality of child care centers, and the effort of the child caregivers might be
responsible for the reversal of health between Muslim and Hindu children.
This may especially be possible as the responsibility for child care and nutrition
intake shifts (during the day) from the mother to the Anganwadi worker. In fact when we
used health data collected in this setting in 2010, to run a simple regression of malnutrition
status on child observables (age, gender) and mother’s characteristics (education, income,
assets, occupation), we are only able to explain 2 percent of the variation in malnutrition.
Adding Anganwadi fixed effects increases the R-squared to 10 percent, suggesting that the
day care environment may be a significant correlate in determining the health status of a
child.3 This suggests the importance of Anganwadi workers in influencing the health status,
and in particular the potential detrimental effect on health if they are not conscientious

enough or strategically choose whom to help and whom to ignore. For example, Anganwadi
workers might not always allocate greater effort towards those who are more malnourished,
but instead exert greater effort towards supporting religious in-group members opening up
the possibility of religious discrimination (Singh and Mitra forthcoming).4
Our interest here is to evaluate and elicit whether workers have preferences for
members of the same religious group. If they do, it might provide a supply side explanation
to unequal health outcomes among children of the two religious groups. Moreover, religious
background could also serve as a proxy for other unobservables such as child’s nutritional
status or socioeconomic background that may induce workers to change their own behavior
towards the two groups inducing statistical discrimination. In the paper, we distinguish
between the two sources of discrimination and the games are designed to elicit both. We
focus exclusively on Anganwadi workers who are Hindu, especially since almost all (97.8%)
of the health care workers in our sample are Hindus. We are not in a position to evaluate
discriminatory attitudes of Muslim health care workers towards Hindu children due to the
lack of observations on Muslim workers in our sample.
3. Experiment
3.1 The Discrimination Game
We designed an allocation game (the Discrimination Game) where each health care
worker5 (Anganwadi worker) allocated a fixed sum of money between mothers of two
4 In Chandigarh, 80.8 per cent of the population is Hindu and 4.9% is Muslim. In Delhi, 81.2% of the population is Hindu and 12.9% is
Muslim (Census of India 2011).
5 We use the terms Anganwadi worker, child caregiver, and health worker interchangeably throughout the paper.

randomly chosen pre-school age children.6 Each worker’s allocation decision was observed
under the following three treatments: (1) information and no-identity (INFO-NOID), (2)
information and identity (INFO-ID), (3) no-information and identity (NOINFO-ID).7 In
each treatment, the worker received Rs. 120, to divide between two mothers.8 She had to
choose from one of the four allocation options listed in Table 1. Since we wanted to elicit
workers’ distributional preferences for children with different religious identities, we
purposely kept the amount the worker can allocate to herself fixed in all choices to control for
selfish payoff-maximizing preferences across the treatments and focus exclusively on
distribution attitudes towards others.9 Subject instructions are provided in Appendix A2.
In the INFO-NOID treatment, the worker had no information on the child’s religious
identity. She was only told that both children suffer from grade 2 malnutrition or moderate
levels of undernutrition as measured by weight-for-age z-scores (see instructions for Task 1,
Appendix A2).10 Observed choices in this treatment allowed us to rule out any irrational
behavior among our subjects when they are not provided any information on the recipients’
religious identities. We should expect the modal choice to be the equal split.
In the INFO-ID treatment, the worker was provided with the names of the two
children where child 1 had a Muslim name and child 2 had a Hindu name. Further, she was
provided the information that both children suffer from moderate levels of undernutrition as
6 Lane (2015) in his meta analysis notes that the extent of discrimination against the out-group is strongest when the decision making
subject is asked to allocate payoffs between inactive players belonging to the in-group and out-group, it is stronger than in any other
decision-making context.
7 Fershtman and Gneezy (2001) and List (2004) both use a dictator game where the amount transferred by player A (dictator) to player B
(receiver), if affected by player B’s background characteristic, is a strong indication of taste-based discrimination.
8 Rs. 120 is equivalent to 2 USD at the prevailing exchange rate at the time.
9 This is in contrast to other papers that also allow the dictator to keep the money for themselves, allowing them to exploit their dictator
position (Fershtman and Gneezy 2001; List 2004).
10 In the context of the weight-for-age z-score measure used by Anganwadis, moderate malnutrition is defined as the child being between 2
and 3 standard deviations below the WHO specified mean for the reference population of the same age and sex. In Chandigarh, about 41 per
cent of the children enrolled in these centers were malnourished in July 2014 (Singh and Masters 2016).

measured by weight-for-age z-scores (see instructions for Task 2, Appendix A2). Since both
children suffer from equal degrees of malnutrition, unequal allocations in favor of the Hindu
(or the Muslim) child would indicate taste-based discrimination. 11 It is important to note here
that to minimize experimenter demand effects, we avoided providing explicit information on
religious identity. So instead of stating “mother of Hindu child” or “mother of Muslim child”,
we provided the child’s name. Here we made use of the fact that Muslim and Hindu children
generally have easily distinguishable names (see for example Banerjee et al. (2009) who
suggest that, “Muslim names were universally recognized as such”). Additionally, we
provided the decision maker with other information such as the health status of the child to
obfuscate experiment demand effects further (see discussion in Berge et al. 2015). In March,
2017 we followed up with a phone survey to verify whether our participants can actually
identify the religion and the gender of the children based on the names we had used. We
found that 100% of our sample that could be surveyed on the phone could correctly identify
the religion and the gender correctly.12 Finally, note that the main results reported in Table 4
continue to hold for the sample of women who participated in our phone survey (see
Appendix Table A2).
In the NOINFO-ID treatment, there was no information on the child’s nutritional
status. The workers only received information about the child’s name. In this treatment,
unequal allocation in favor of the Hindu (or the Muslim) child would indicate the presence of
11 In the lab-in-the-field experiments conducted in Chandigarh, workers were making choices over actual Hindu and Muslim children living
in another part of the city.
12 We thank Daniel Houser for this useful suggestion. We targeted all 75 Anganwadi workers who participated in our incentivized
experiments in Chandigarh via phone and were able to reach out 90.67% of these women. In New Delhi, we targeted 99 of the 108 workers
for whom contact numbers were available and were able to reach out 92% of these women. We find the response rates to be similar across
treatments in both Chandigarh and New Delhi. In Chandigarh, 89% of the workers in the INFOID treatment and 92% of the workers in the
NOINFO-ID and INFO-NOID treatments participated in the phone surveys. This difference is not significantly different (p-value = 0.72). In
New Delhi, 93% of the workers in the INFOID treatment and 91% of the workers in the NOINFO-ID and INFO-NOID treatments
participated in the phone surveys. This difference is also not significantly different (p-value = 0.71).

discrimination that can accrue to taste or statistical sources (see instructions for Task 3,
Appendix A2). We subtract the differences in allocations between the recipient mothers of
the two children in INFO-ID treatment from the differences in allocations between the two
children in the NOINFO-ID treatment to disentangle the presence (if any) of statistical
discrimination from taste-based discrimination.

3.2 Religious preference and behavior
We provide below a simple model to explain religious preference and plausible
behavior in our experiment design where we modify the basic setup in Berge et al. (2015) and
Cappalen et al. (2007) for our specific purposes. The allocator i, has to divide a fixed sum X
between an in-group member and a member of the out-group. Suppose he proposes an
amount xIN for the in-group member and xOUT =X – xIN for the out-group member. In our
specific context in-group members share the same religion, while out-group members do not.
We assume that the allocator i has a simple utility function of the following
form:
11
!!(!!") = !! . !!" − !! .(!!" −!!)!
2!
where !! ≥ 0 is the parameter of religious bias, !! > 0 is the parameter for fairness, and m is
the amount the allocator believes to be a norm dependent fair share in the absence of
information on religious identity. Note that our utility function differs from a typical utility
function in that there is no own payoff maximizing option. This is in line with our experiment
design where the allocator’s own payoffs are always fixed. Hence the utility comes from in-
group bias and preference for norm-dependent fairness. The norm dependent fairness can
depend on the context. For example the allocator might believe that a poor should get more
than the rich, or females should get more than males, etc. Notice then for a given value of !,
the allocator’s utility increases with an increase in the proposed share !!", and additionally,
deviations from m affect his/her utility negatively.
Given an interior solution, the optimal proposal for xIN would be
!!"∗ = !! + !! .!!
Hence the optimal proposed share depends on the norm dependent fair share along with the
sensitivity towards sharing with in-group members. Further, when the allocator has no
preference for in-group members, i.e., ! = 0, the allocator allocates based on his/her norm
dependent fair share independent of any religious favoritism. Similarly, if !! → ∞ ,
!! . !! → 0, and hence preference for socially desirably fairness norms become more
important than any in-group bias in deciding allocation amounts. In that case, even though
religious discrimination tendencies are absent, allocation outcomes can be different than an
equal split allocation based on underlying social attitudes and norms towards other social
parameters.

3.3 Design and protocol
Our experiment sessions were conducted among Anganwadi workers in Chandigarh and New
Delhi in India. In the baseline INFO-NOID treatment, we randomly chose two mothers of
pre-school age children (from Anganwadis in another geographical block) to receive the
payouts chosen by the worker in the experiment. In INFO-ID treatment and NOINFO-ID
treatments, the religious identities of the recipient mothers were disclosed by providing the
names of their children. In all treatments we chose names of males to control for any gender
preference. The recipient mothers in all treatments were chosen from a different geographical
zone to minimize the possibility of strategic interactions and/or familiarity bias.
We chose to randomly assign subjects either to a single treatment session consisting
of only treatment 2 (the information and identity treatment), or a session consisting of
treatments 1 and 3 (the information and no-identity treatment and no-information and identity
treatment).13 While we would have ideally liked to randomize subjects into one and only one
of the three treatments, we were constrained by sample size. We made the choice of assigning
treatment 1 with treatment 3 because treatment 1 was really a game to check for rational
choice since it did not include information on our main variable of interest, the religious
identity. We further reasoned that putting treatment 1 and 2 together might make subjects
more conscious of our ultimate interest as they participate in the two treatments sequentially.
This was not the case if we put treatments 1 and 3 together since they appear as eliciting
13 The power of an experimental design gives, for a given effect size and statistical significance level, the probability that we will be able to
reject the hypothesis of no treatment effects when it is false. In Figure A1 of the Appendix we show the minimum sample size required to
detect a medium effect size of 0.45 standard deviation at the 5 percent significance level. Figure A1 in the Appendix shows that we need a
total of approximately 150 workers (approximately 75 workers in each treatment) to secure an 80 percent chance of rejecting the null of zero
treatment effects when it is false. Note that our power calculations are based on pooling the two samples from Chandigarh and New Delhi.
Also note that the main results in the paper hold for the pooled sample and are available from the authors.

distribution choices under two different environments, one conditional on health status and
the other conditional on religious identities.
Chandigarh Sessions: The Anganwadi workers were paid a show-up fee of Rs. 50 for
participating in the experiment. The invitations were sent to all possible Anganwadi workers
employed in the ICDS’ Block 1 slum areas in Chandigarh. In total, over 90 per cent of the
invited workers participated. If a subject participated in the multiple treatment session we
randomly chose one of the treatments for additional payments to avoid wealth effects.
Average payout per subject in Chandigarh is Rs 120.
New Delhi Sessions: These were non-incentivized sessions. A comparison of results from the
incentivized and non-incentivized sessions allows us to comment on the substitutability of the
two design choices (Coppola 2014; Dohmen et al. 2011; Gneezy and Rustichini 2000).
Additionally, it provides insights into the role of monetary incentives among health care
workers. All session-related information is reported in Table 2.

4. Results
4.1 Main findings
14
Subject randomization into different treatments was successful. We find no significant
difference in the family background characteristics between Anganwadi workers assigned to
each of the treatments in Chandigarh as well as in New Delhi, verifying balance among
subject characteristics in each of our treatments (see Column 3, Table 3).
We categorize subjects’ behavior in the experiment into three groups: (1) equal split: subject
chooses to give equally to both mothers, (2) pro-Muslim: when the subject chooses to give
more to the mother of the Muslim child, and (3) pro-Hindu: when the subject chooses to
give more to the mother of the Hindu child. Note that by design, religious identity was not
available to the subjects for our baseline treatment (INFO-NOID). They were asked to choose
between giving more to child 1 or child 2, or an equal split. Figure 1 summarizes the average
choices made in the experiment. More than 80 per cent of the subjects chose to allocate
equally to both mothers in all three treatments.

Notes: The same subject makes decisions in treatments 1 and 3.
In the INFO-NOID treatment, where there was no information on religious identities of the
recipients, we expect the workers to allocate their resources equally between the two mothers
(barring any irrational choices or order effects). In the INFO-ID treatment, when religious
identity was provided and the two children were described to be moderately malnourished,
the presence of taste-based discrimination would suggest a choice of unequal allocation
among the two mothers. In the NOINFO-ID treatment, where only information on religious
identity was provided, but information on the children’s nutritional status was not revealed,
taste-based as well as statistical discrimination would lead to unequal allocation for the two
mothers. We set up the three hypotheses accordingly on rationality, taste-based
discrimination, and statistical discrimination in Table 4. Our findings in Table 4 establish the
following. First, with the information on the health status of the children and no other
information, the workers equally divided resources between both mothers - H1 cannot be
rejected. Second, in the presence of information on religious identity, subjects did not
discriminate on the basis of religious identity - H2 cannot be rejected. Third, there was no
evidence of statistical discrimination - H3 cannot be rejected.

Results from our experiment suggest that there is no evidence for taste-based or statistical-based
discrimination in our sample. Additionally, when we compare observed outcomes from the incentivized
experiments in Chandigarh with the non-incentivized experiments in New Delhi, we find no difference in
our conclusions for each of the hypotheses (See p-value of differences in Column 3, Table 4). Weak
evidence or absence of it for discriminatory preferences however might arise from three different sources
in our experiment. First, it might be due to low statistical power. Second, there might be a lack of saliency
across treatment conditions leading subjects to choose the same in all treatments. Third, experimenter
demand/scrutiny effects might attenuate underlying discriminatory tendencies. We try to mitigate some of
these concerns next.
4.2 Statistical power
As described in footnote 12, our study is already designed to detect medium effect sizes. However, to rule
out additional sample size related concerns, we report results from the bootstrap technique outlined in
Moffat (2016).14 We compute bootstrap standard errors using 999 replications for a two-tailed test at the
5 percent significance level. In Table 5, we replicate our main findings with bootstrap p-values. The p-
values reported in Table 5 are consistent with our main findings of no religious discrimination (either
taste-based or statistical).

14 Adèr et al. (2008) points out: “When the sample size is insufficient for straightforward statistical inference, if the underlying distribution is
well-known, bootstrapping provides a way to account for the distortions caused by the specific sample that may not be fully representative of the
population.”

4.3 Treatment saliency
Since we find no evidence of religious discrimination (taste or statistical) in our sample, it is
possible that workers are indifferent to the information provided in the three treatments and
consequently choose the equal split rational outcome in each treatment. However, this would
suggest that we should observe similar equal split choices in other informational conditions as
well. To rule out saliency concerns, we ran an additional experiment with a different sample of
Anganwadi workers in Chandigarh in January, 2016.
Here we test whether workers remained indifferent to other types of information. As before,
workers were asked to allocate a fixed amount between two mothers with different
characteristics: (a) mother of a moderately malnourished and mother of a healthy child, (b) a
poor and a rich mother, (c) an illiterate and a literate mother, (d) a non-working and a working
mother, (e) a mother with low household assets and one with high assets, (f) a mother with a
physically challenged child and a mother with a child without any disability, and finally (g) a
mother of a boy and a mother of a girl. Forty-nine workers participated in the experiment. Only
situation (a) was incentivized and the remainder were thought experiments along the lines of the
earlier Delhi experiment.
20
In Figure 2, we find that workers make allocation decisions based on a number of
characteristics. In particular, they provide significantly greater amounts to (a) the mother of a
moderately malnourished child, (b) the poor mother, (c) the illiterate mother, (d) the non-
working mother, (e) the mother with low assets, and (f) the mother with a physically challenged
child. Moreover, the proportions are much large for (b), (e), and (f) compared to (a) and (c),
suggesting that some social norms and attitudes towards social justice might influence the
workers more strongly. For example, workers might prefer to give more to those they think are
less able to fend for themselves and their children. For (g), we do not find significant differential
allocation by child’s gender and the sign predicts favorable treatment towards girls (See
Appendix Table A1 for related hypotheses and results). The results suggest that although
religious preferences do not affect subject choices, welfare-based and desert-based distributive
principles seem to influence workers’ allocation decisions (Feinberg 1970, Rescher 1966). Also
ruling out small sample size driving the main null findings.

4.4 Experimenter demand and scrutiny effects
Finally, as indicated earlier, our experiment is designed to minimize the experiment
demand effects in two important ways. First, instead of directly assigning religious identities
(Hindu or Muslim) we make use of names that reveal religious identity (e.g: Amit or Akbar).
Second, additional information on the children’s health status along with mothers being the
payoff recipients can help minimize the focus on religion for the decision maker.
5. Discussion
In economics generally, and development economics in particular, there has been an
intentional shift towards more evidence-based policies. Policies that address discrimination
are no exception. However, the nature of policies is likely to be very different depending
upon the sources of discrimination. For example, policies targeting intrinsic hatred towards
another group could involve either a “soft” solution like changing perceptions or a “hard”
solution like punishment for racism. On the other hand, statistical discrimination could be
attenuated by providing more information about factors for which religion is being viewed as
a proxy.
In this paper, we design an experiment and introduce a novel allocation game to
identify statistical and taste based discrimination among government-employed pre-school
caregivers in India. Our results suggest that among childcare workers in Chandigarh and New
Delhi there is no evidence of either taste-based or statistical religious discrimination.
Anganwadi workers in our sample do not seem to discriminate along religious lines; instead
they seem to exhibit a social-justice-based attitude towards the poor and the undernourished.
We also find that incentivizing decisions does not change their allocation behavior. It is
plausible that these findings may be specific to public health workers who may be
23
intrinsically motivated and are often identified as different from professionals in other
sectors.
Our elicited preferences thorough experimental tasks also seem to support findings
from primary data collected on health status of children in these geographical areas. Singh
and Masters (2016) collected data on weights of children present in the universe of 245
Anganwadis located in urban slums of Chandigarh to find that the weight-for-age
malnutrition rates are nearly identical for both Hindu and Muslim children in Chandigarh, at
37.5% and 38.2% respectively. While this is encouraging from a policy perspective, the lack
of evidence on religious discrimination does not imply that such practices are absent in other
areas of public health, or among Anganwadi workers in other states in India. Further work to
evaluate such evidence in an experimental framework can give us clues about the sources of
discrimination based on religion, skin color, ethnicity, caste or gender.

Instructions for Task 2
Thank you for your participation. You will be paid Rs. 50 for your participation.
Each of you will participate in one task in this experiment. At the end of the task, in addition to the fixed fee, 25 per cent of you will be randomly chosen for additional payments. Here is a bag that contains tokens with all subject IDs written on them. One of the workers will be asked to pick a certain number of these tokens and announce the IDs. For example, if there are 40 participants in a session, we will pick 10 IDs and pay the participants who have those IDs. These randomly chosen participants will be paid according to their decision made on this task.
It is important that you read the instructions for the task before making a decision. If you do not understand, you will not be able to participate effectively. In case you have a question while reading the instructions, please raise your hand and we will escort you to the nearby room and clarify your query.
Each page has an ID# on it. Do not show this ID# to any other participant or allow it to be visible to anyone during or after this experiment. There should be no talking or discussion of the task amongst you while waiting for the experiment to begin. We request you to remain seated, and not do anything unless instructed by the experimenter. Also do not look at others’ responses once the experiment begins. You might be disqualified otherwise.
If you are ready, then we will proceed.
Each of you will make decisions that will decide your own payouts and the payouts of mothers of two randomly chosen pre-school children. The children will be chosen from our sample through a lottery. They belong to an Anganwadi Center in an urban slum of Chandigarh that is not in your block. Note that only mothers of children identified as “moderately malnourished/suffer from grade 2 malnourishment” are eligible to receive the payouts from the experiment.
All decisions will remain private, and no one will get to know who was matched with whom (either during, or after the experiment due to the code structure of the experiment).
In this task you have inherited Rs. 120. Your task is to decide on how much of that money you want to keep for yourself, how much of it you want to give to give to the two randomly chosen mothers of grade 2 malnourished children.
Please choose only one of the following four options: A, B, C or D. Notice that in all the options, the sum of the allocations between you, mother of child 1, and mother of child 2 should add up to Rs. 120. Note that child 1 and child 2 are both “moderately malnourished/suffer from grade 2 level of malnourishment.”
After marking your decisions please fold your response sheet and place it in front of you. The experimenter will collect them.

General Instructions for Tasks 1 and 3
Thank you for your participation. You will be paid Rs. 50 for your participation.
Each of you will participate in two tasks in this experiment. At the end of the two tasks, in addition to the fixed fee, we will randomly choose one task for which some of you will also receive additional payments.
On the table at the front of the room are 2 cards, each with 1, or 2 written on them. They are kept facing down so that the numbers are not visible. We will ask one of you to pick one of the cards and announce the number written on that card. That particular task will then be used for making the additional payments for this session. For example, if the worker picks a card with 1 written on it, task 1 will be used for making the additional payments. After a specific task has been chosen for payments, 25 per cent of you will be randomly chosen for the additional payments. Here is a bag that contains tokens with all subject IDs written on them. One of the workers will be asked to pick a certain number of these tokens and announce the IDs. For example, if there are 40 participants in a session, we will pick 10 IDs and pay the participants who have those IDs. These randomly chosen participants will be paid according to their decision made on the task that was chosen for the additional payments.
We are about to read the instructions for the two tasks. Please listen carefully. It is important that you read the instructions for the tasks before making a decision. If you do not understand, you will not be able to participate effectively. In case you have a question while reading the instructions, please raise your hand and we will escort you to the nearby room and clarify your query.
Each page has an ID# on it. Do not show this ID# to any other participant or allow it to be visible to anyone during or after this experiment. There should be no talking or discussion of the task amongst you while waiting for the experiment to begin. We request you to remain seated, and not do anything unless instructed by the experimenter. Also do not look at others’ responses once the experiment begins. You might be disqualified otherwise.
If you are ready, then we will proceed.
Instructions for Task 1
Each of you will make decisions that will decide your own payouts and the payouts of mothers of two randomly chosen pre-school children. The children will be chosen through a lottery from an Anganwadi Center in an urban slum of Chandigarh that is not in your block. Note that only mothers of children identified as “moderately malnourished/suffer from grade 2 level malnourishment” are eligible to receive the payouts from the experiment.
All decisions will remain private, and no one will get to know who was matched with whom (either during, or after the experiment due to the code structure of the experiment).

Please choose only one of the following four options: A, B, C, or D. Notice that in all the options, the sum of the allocations between you, mother of child 1, and mother of child 2 should add up to Rs. 120.
