What is it?
The idea of PJEM was born from the observation that few Ph.D. students/juniors at our University work on experimental economics. Thus, we had the idea to organize informal seminars to discuss experimental designs and projects and create a community of junior experimentalists in Paris and its suburbs: Paris Junior Experimentalists Meetings (PJEM). The idea is to meet at a bar and to present and talk informally, over a drink, about your ongoing research. You can present your paper at any stage, even if you only want to present your experimental design, or if you already have run your sessions and you want to talk about the results.
If you want to present your work or just attend the presentations, subscribe to our mailing list!

Perceptions of inequality: When the grass is less green on the other side
Claire Mollier (Prague University of Economics and Business)
Abstract:
This study explores how individuals perceive and respond to wealth inequalities based on intergroup comparisons. Specifically, we examine whether individuals tend to minimize the inequalities they experience when they observe more pronounced disparities in another group. To investigate this, a laboratory experiment is conducted where participants are matched into groups of two players. Subjects receive different allocations within their group and different types of information regarding the other group: no information, the wealthiest’s allocation, the poorest’s allocation, both allocations, and the actions to not reduce inequalities within the group. Data shows that disclosing both the other group’s members allocations, and hence their (higher) level of inequality, negatively impacts the willingness to move towards a more equal situation. Revealing the allocation of the wealthiest or the other group’s decision not to redistribute enhance the perceived fairness of the allocation received.
