Forest protection contributes to climate change mitigation and biodiversity conservation. Yet negative income shocks can induce local forest users to increase extraction in order to cope with economic hardship. We study how social norms shape collaborative forest management when communities face...

This paper studies whether alternative integration-policy framings affect cooperation in ethnically diverse groups. We conduct a lab-in-the-field experiment with 390 adolescents in mixed classrooms in Italy. Within each class, students were randomly assigned to small groups that received either...

Der Green Startup Report 2026, herausgegeben vom Borderstep Institut für Innovation und Nachhaltigkeit, analysiert die aktuelle Entwicklung der grünen Gründungslandschaft in Deutschland und setzt die seit 2013 kontinuierlich durchgeführte wissenschaftliche Beobachtung der Szene fort. Die...

This essay suggests that the evolution of human cooperation over the course of human history should be viewed as a two-layer process. A foundational layer, rooted in subsistence and ecological pressures, shaped cooperative dispositions unevenly, whereas an expansionary layer, rooted in conflict...

This paper studies whether alternative integration-policy framings affect cooperation in ethnically diverse groups. We conduct a lab-in-the-field experiment with 390 adolescents in mixed classrooms in Italy. Within each class, students were randomly assigned to small groups that received either...

This paper investigates gender-based differences in cooperativeness among French parliamentarians by analyzing legislative behaviors, such as cosponsorship and voting patterns. Using a comprehensive dataset covering all bills and amendments authored in France's Lower House between 2012 and 2022,...

We review the social science literature on trust and cooperation with application to labourmanagement relations. We begin with the neo-classical economic view of self-regarding individuals operating with perfect information and show that once one abandons the dyadic case with perfect...

Gallice and Monzón (2019) present a natural environment that sustains full cooperation in one-shot social dilemmas among a finite number of self-interested agents. They demonstrate that in a sequential public goods game, where agents lack knowledge of their position in the sequence but can...

Experiment participants in a social dilemma game choose cooperation over defection, even though neither is more beneficial. High levels of cooperation cannot be explained by favorable labels for actions, collusion, k-level reasoning, quantal response behavior, or misplaced optimism about others'...

Interrelated global crises - climate change, pandemics, loss of ecosystem services and biodiversity - pose risks that demand collective solutions. Uncertainty about others' behavior, coupled with the dependence on some to take collective efforts to mitigate risks for all (e.g. conservation of...

Living organisms expend energy to sustain survival, a process which is reliant on consuming resources - termed here as the "cost of survival". In the Prisoner's Dilemma (PD), a classic model of social interaction, individual payoffs depend on choices to either provide benefits to others at a...

With the growth of the digital economy and environmental concerns, an increasing number of manufacturing firms are leveraging digitalization to advance their green innovation and sustainable development. Although previous studies have examined the impact of digitalization on green innovation,...

This paper studies how competition between groups affects cooperation. In the control condition, pairs of subjects play an indefinitely repeated Prisoner's Dilemma game without external competition. In the treatment, two pairs compete against each other. No monetary rewards are tied to winning,...

For years, federal politicians from all established parties have categorically ruled out any cooperation with the Alternative for Germany (AfD), erecting a so-called "firewall" ("Brandmauer") against the party. Nevertheless, reports increasingly document instances where this firewall is eroding,...

Social cooperatives, which are an important pillar of the solidarity economy, have become increasingly popular and common in Hungary over the past 10 years, especially in disadvantaged settlements, where the administrative burden of public employment is outsourced to social cooperatives....

We analyze infinitely repeated multiplayer prisoner's dilemmas in continuous-time experiments. As the number of players changes, our design keeps the payoffs of the all-defection, all-cooperation, and unilateral- defection and -cooperation outcomes constant, thus controlling for the minimum...

The well-known prisoner's dilemma shows why cooperation may be difficult to achieve even when cooperation would create value for all partners. In particular, material interests conflict because reciprocity cannot be enforced, while agents give priority to their material self-interest. This paper...

WORTH Partnership Project was funded by the European Commission under COSME, the EU Programme for the competitiveness of Small and Mediumsized Enterprises. WORTH was the sole European project where designers, SMEs, manufacturers, and tech providers worked together to develop innovative,...

This paper investigates how institutional and social trust respond to crisis situations, and to what extent different kinds of trust interact in such a context. In an online survey experiment on 4,400 representative respondents from Italy, participants are exposed to a real-world flooding...

2024 was a year that saw Europe face numerous challenges, yet make significant strides in food safety. This annual report of the Alert and Cooperation Network (ACN) is an opportune moment to take stock of the evolving landscape in food and feed safety and to explore the complexity of emerging...

As Europe's closest neighbour and strategic partner, Africa shares strong ties and mutual interests with the European Union. Their partnership is evolving into a forward-looking alliance addressing critical global challenges such as climate change and clean energy transition in support of...

Human cooperation is ubiquitous and instinctive. We are among the most cooperative species on Earth. Still, research mostly focuses on why we cooperate, instead of understanding why some of us do not do so. The public goods game can be used to map human cooperation as well as to study free...

Should gender composition be taken into account when forming teams? This paper examines how the output of teams completing tasks similar to those performed in many workplaces is influenced by their gender composition. Leveraging an economics bachelor course in which students are randomly paired...
