<title>Abstract</title> Collective action problems emerge when individual incentives and group interests are misaligned, as in the case of climate change<sup>1–5</sup>. Individuals involved in collective action problems are often considered to have two options: contribute towards a public solution or free-ride. But they might also choose a third option of investing in a private solution such as local climate change adaptation<sup>6–8</sup>. Here we introduce a collective action game featuring wealth inequality caused by luck or merit and both public and private solutions with participants from 34 countries. We show that the joint existence of wealth inequality and private solutions has a consistent effect across countries: participants endowed with higher income choose the private solution almost twice as often as those endowed with lower income; and this finding cannot be explained by different sources of wealth (luck vs. merit) or by cultural or economic factors. We also show that preferences for private solutions undermine support for public solutions, resulting in wealth inequality increasing in every country. In contrast, we identify two universal pathways to successful public solution provision: early contributions to public solutions and conditional cooperation. Our findings highlight the ubiquity of the ‘private solution problem’ and its potential consequences for global collective action problems.

The baking of preferences throughout the high school
(2024) Antonio Alfonso; Pablo Brañas‐Garza; Diego Jorrat; Benjamin Prissé; María José Vázquez de Francisco
The purpose of this study is to examine whether girls and boys exhibit different risk and time preferences and how this difference evolves during the critical phase of adolescence. To achieve this, we use a large and powered sample of 4830 non-self-selected teenagers from 207 classes across 22 Spanish schools with very different socioeconomic backgrounds. Alongside time and risk preferences, we also collected additional information about class attributes, social network measures, students' characteristics, and the average level of economic preferences of friends. These measures enable us to account for potentially omitted variables that were not considered in previous studies. The results indicate that there are no significant gender differences in time and risk preferences, but older subjects exhibit more sophisticated time preferences and higher risk aversion. We also perform an exploratory heterogeneity analysis, which unveils two important results: first, cognitive abilities play a critical role in the development of time and risk preferences; second, interaction within the class social network does matter.

Triadic influence as a proxy for compatibility in social relationships
(European Organization for Nuclear Research, 2023) Miguel Ruíz-García; Juan Ozaita; María Pereda; Antonio Alfonso; Pablo Brañas‐Garza; José A. Cuesta; Anxo Sánchez Sánchez
This dataset contains valuable information that allows for the recreation of the paper "Triadic influence as a proxy for compatibility in social relationships" which was published in PNAS. The dataset comprises 13 high school networks that represent the diverse social relationships that exist between students within each school. To construct each of these networks, you can utilize the "Edges_i.csv" and "Nodes_i.csv" files, which are available for download in the files section. The edges files provide data on weighted edges, where the weight varies between -2, -1, +1, and +2. The sign indicates the nature of the friendship, while the number corresponds to its intensity. On the other hand, the node files contain information about the age level, group, sex, and psychological attributes such as CRT and prosociality.
