Economists have now recognized that agents' social perceptions and relations shape economic interactions. We propose a novel experiment with the objective to study whether the opposite direction is operative, namely whether the economic setting affects agents' social perceptions and potential relations with others. Our treatments exogenously vary the economic setting, and in a cross-subject study, subjects are asked their social evaluations of others in the different settings.

Primary Outcomes

Primary Outcomes (end points)
For each subject, the key outcome variables are (i) the experimental treatment he/she went trhough, (ii) the stated closeness, similarity and commonality to the matched partner, (iii) the objective commonality constructed using the answers to the Study Questionnaire of the subject and the matched partner.

Experimental Design

Experimental Design
Our experiment has 4 Parts. In the first, each subject is asked to complete a Study Questionnaire on his/her own personal attributes and preferences. In Part 2, the subject performs some tasks. In Part 3, the subject is involved in a simple economic interaction with two randomly selected subjects who previously completed the Study Questionnaire. In Part 4, the subject sees the answers to the Study Questionnaire that were given by one of these two individuals. The subject is asked to assess his/her closeness and similarity to this person, and how many profiles items in the Study Questionnaire they have in common. Our objective is to study how the economic interactions built in Parts 2 and 3 affect social perceptions elicited in Part 4.
Experimental Design Details
Randomization Method
The subjects will be recruited on the platform Prolific.
For Study 1, they will all go through the exact same survey.
For Study 2, they will be randomly assigned to one of our 4 experimental treatments (by a random number generated within Qualtrics).
Randomization Unit
Individual subject.
Was the treatment clustered?
