Part I:The contribution of religion to social trust (i):
What is religion? Very difficult to define
Three elements commonly cited – none either necessary or sufficient
Belief in the existence of invisible spirits that intervene causally in the world and that can be influenced by appropriate appeals from human subjectsImportance of ritual activities, both collective and individualA distinction between the sacred and the profane

The contribution of religion to social trust (ii):
Religions potentially have characteristics that enable their members to have more mutual trust
Opportunities to observe the behavior of others; sharing of informationSanctions (exclusion etc) in case of breaches of trustFaith as a signal of belief in the presence of supernatural norms and sanctions

The contribution of religion to social trust (iii):
5
How to avoid hypocrisy? The answer: costly signaling
The genuinely trustworthy must be more willing than others to pay the cost of religious membership
Three kinds of mechanismPayments for membership (tithes etc)Behavioral restrictions (diet, lifestyle)Supernatural beliefs, genuinely held and impacting individual decisions
![Page 6: A Micro level study on Investment in Haiti](https://reader033.fdocuments.us/reader033/viewer/2022042908/58ed44461a28ab36088b458d/html5/thumbnails/6.jpg)
The contribution of religion to social trust (iv):
What can an experimental study contribute to understanding religion? The answer: studying genuine beliefs
Religious belief and practice in real life are complicated, multi-dimensional activitiesDifficult to disentangle genuine beliefs from behavior intended to be observed by othersAn experimental setting can distinguished genuine (truly anonymous) choices from those observed by others

The contribution of religion to social trust (v):
Empirical questions: Can we tell genuine from non-genuine religious adherents?Are genuine religious adherents more trustworthy than non-adherents? If so:Does religion change individual behavior or does it attract more trustworthy people?Are they more trustworthy towards everyone or just towards their co-religionists?

If religious adherents are more trustworthy than other people, four possible cases:
Religions lead their adherents to behave in a more trustworthy way than they would otherwise
Religions attract adherents who behave in a more trustowrthy way in most contexts
Religious adherents are more trustworthy just towards co-religionists
Theory of clubs Theory of coevolution of altruism and xenophobia
Religious adherents are more generally trustworthy, not just towards co-religionists
Theory of social norms sustained by natural or supernatural sanctions
Theory of costly signaling

Religion in the Haitian context
Traditionally Catholic country in which protestant denominations have made large advances in recent years. Strong competition between denominations
Voodoo practices quite common among both Catholics and Protestants, but still shrouded in secrecy
Practices repressed by both indigenous and foreign authorities, denounced by churches, only accepted in last 10 years
Great pragmatism of both adherents and practitioners..

Part II: the purpose of our study
To study the role of religion in building social trust; Haiti is a country with low levels of social trust, poorly developed financial institutions and weak civil society outside religion
More specifically, to test experimentally the theory that religion is a costly signal of trustworthy behavior the theory that religion helps to reduce moral hazardthe theory that religion is a club good
Additionallyto find ways of diagnosing some characteristics of genuine religious beliefto see whether religion is associated with an ability to facilitate economic exchanges

Two phases of the study:
Phase 1 (April-July 2012): Questionnaire study250 subjects interviewed in 11 localities in 3 regions (in kreyol)Questions on economic activities and interactions, important life-cycle eventsUse of principal components analysis to understand beliefs and exchanges
Phase 2 (December 2012 - February 2013): Economic experiments
832 participants, 35 sessions, 6 regions; all experiments conducted in kreyolTwo experiments: lotteries and trust games Classic baseline versions and treatment with (costly) images Questions on social-economical-religious activities of the participants 12

Main differences between the phases
Phase 2 subjects contained fewer women, fewer illiterates, fewer elderly
More students, Protestants, owners of mobile phones and those with access to internet
Does this introduce bias? Maybe, but hard to see in which direction
![Page 17: A Micro level study on Investment in Haiti](https://reader033.fdocuments.us/reader033/viewer/2022042908/58ed44461a28ab36088b458d/html5/thumbnails/17.jpg)
Second phase of the study: ‘Field lab’
Subjects participated in sessions lasting 2-3 hours with 17 to 25 subjects per session; sessions in schools or village halls (not in religious institutions); recruitment by word of mouth via mayors etc
Anonymity among participants and towards the experimenters
Order of lottery and trust game varied across sessions, also order of image treatments. No influence of game order on results.
Closed answers questionnaires after the experiments were performed.
Payments based on points accumulated, totals between c.90-250 gourdes (€1.80 to €5)

Description of the experiments:
Lottery: Each subject has 10 tokensCan gamble 1 to 10 tokens, with probability 60% the stake is doubledA neutral baseline game, then three games with 7 or 8 tokens plus one image (price and image order randomized by session)A last game where subjects can choose which to play again
Trust game:Each subject has 5 tokens and can send to a trustee a sum that is tripled Trustees can keep sum or send a proportion back to the sender Neutral game as sender then receiver, plus one game with choice of image as sender Two games with images as receiver, 6 and 12 tokens, random image

Are image choices observed?Lottery:
Subjects choose in secret (in a closed box) and place the image in an opaque mug The try hard to hide the transfer of the image, suggesting they believe their choice is genuinely secretWe interpret this choice as indicative of “genuine” belief
Trust game:Subjects choose in secret, but they know their choice will be observed by the receiver of the money sent (the ‘trustee”)They may have a motive to choose an image to influence the decision of the other to return a higher proportion to themWe interpret this choice as potentially “strategic”

Results of the experiments in brief
Lots of subjects buy images – 75% in at least one game!
Image buyers are different from non-buyers (less risk averse, more trusting)
“Genuine” image buyers are more trustworthy than everyone else – and “strategic” image buyers less trustworthy
No difference between denominations
No club good effect
![Page 27: A Micro level study on Investment in Haiti](https://reader033.fdocuments.us/reader033/viewer/2022042908/58ed44461a28ab36088b458d/html5/thumbnails/27.jpg)
Are subjects who pay for images different from subjects who don’t?
Do they gamble more than non-buyers even when playing without the presence of images? YES (though with images they gamble even more)
Do they trust more than non-buyers even without the presence of images? YES
Are they more trustworthy than non-buyers? DEPENDS ON THEIR MOTIVATION FOR BUYING THE IMAGE

Distinguish between different types who pay for images
Although 75.5% of subjects buy in at least one game, only 44.8% buy in both games
Subjects who choose same image in both games can be considered “Genuine” believers
Those who behave differently in the two games are “Strategic” buyers
Those who do not buy in either game are “Non-Buyers”
Genuine believers should reciprocate more than Strategics

Conclusions of Part II
We have tested whether individuals who show a genuine willingness to pay for religious images are more trustworthy than those who do not – we have confirmed this conjecture
This strongly confirms the costly signaling hypothesis
We have found NO support for The moral hazard hypothesisThe club goods hypothesis
![Page 40: A Micro level study on Investment in Haiti](https://reader033.fdocuments.us/reader033/viewer/2022042908/58ed44461a28ab36088b458d/html5/thumbnails/40.jpg)
Part III: Assessing external validity
We use principal components analysis to measureReligious adherence via a range of indicative practices
Participation in borrowing networks
Do measures of religious adherence predict behavior in the experiment – is the experiment capturing recognizably religious behavior?
Does adherence predict borrowing – is there a trust effect on economic outcomes?
![Page 41: A Micro level study on Investment in Haiti](https://reader033.fdocuments.us/reader033/viewer/2022042908/58ed44461a28ab36088b458d/html5/thumbnails/41.jpg)
Principal components analysis:
Useful for reducing the dimensionality of a multi-dimensional measure, on condition that there is a significant correlation between the values on the different dimensions
Consist in finding a weighting of dimensions that explains the maximum proportion of the variance between the observations.
Cannot resolve the problem of how to choose dimensions nor the “optimal” weighting of dimensions if some are more objectively important than others
But can give a measure of central tendency of multiple partial measures of a complex phenomenon, without giving a definition 41
![Page 42: A Micro level study on Investment in Haiti](https://reader033.fdocuments.us/reader033/viewer/2022042908/58ed44461a28ab36088b458d/html5/thumbnails/42.jpg)
Our measures of voodoo belief and general religiosity:24 questions on various practices related to important life events; 11 we interpreted as diagnostic of voodoo beliefs, 13 as more general religiosity
Example of voodoo question: “what do you do to protect your child against harmful magic?”, with replies “bath” or “mystical object (Djok belt etc)”
Example of general religiosity question: “do you clean the tomb of your ancestors every year?”
PCA yields 19.3% of variance due to first PC of voodoo beliefs, 43.7% due to first 317.6% of variance due to first PC of general religiosity, 39.0% due to first 3
Dimensions that are only weakly correlated with the others have little weight in the first principal component
42

How well do these measures predict image choice?

Does subject choose an image in the lottery?
If so, which image?

Now use a general measure of religiosity from PCA of all indicators
We define “overall religiosity” as sum of first three principal components of the whole set of (voodoo plus general) indicators
However, results reported in following slides are broadly robust to choice of indicator, in the sense that religiosity predicts borrowing when using
First p.c. of general religiosity (p < 5%)Second p.c. of general religiosity (p < 5%)First p.c. of voodoo belief (p < 10%)

Understanding borrowing behavior
We use a PCA of four indicators of borrowing (from friends, from neighbors, from relatives, from others)
We use overall religiosity as a regressor, plus economic controls
But religiosity may be endogenous, so we instrument with electricity, access to television, and gender (which is highly significant for religiosity but not otherwise for borrowing)
Religiosity is significant under OLS, but much more important under IV

Summary….
Our measures of religious belief have broadly plausible associations with economic variables: a likely interpretation is that religiosity captures perceived trustworthiness
Two remaining problems: Our belief measures are more effective at explaining choice between images than at choice of image versus no image
Why do people buy trust images when they do not influence behavior of receivers?
Lots of work still to do…
