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...

We study cooperation in an environment where public good providers face the decision to accept a newcomer to their group. A bottom-up process for accepting new members to social groups reveals individual preferences to include newcomers. Alternatively, inclusion can be decided in a top-down...

This research is inspired by in-kind donations that have the capacity to increase the marginal benefit (productivity) in provision of public goods, for example by providing critical infrastructure that increases the productivity of resources utilized by local public good providers. We provide...

Think tanks and political leaders have raised concerns about the implications that the Covid-19 response and reconstruction might have on other social objectives that were setting the international agenda before the Covid-19 pandemic. We present experimental evidence for eight consecutive weeks...

We examine social preferences of Swedish and Austrian children and adolescents using the experimental design of Charness and Rabin (2002). We find that difference aversion decreases while social-welfare preferences increase with age.

Social preferences have been shown to be an important determinant of economic decision making for many adults. We present a large-scale experiment with 883 children and adolescents, aged eight to seventeen years. Participants make decisions in eight simple, one-shot allocation tasks, allowing us...

We compare experimentally the revealed distributional preferences of individuals and teams in allocation tasks. We find that teams are significantly more benevolent than individuals in the domain of disadvantageous inequality while the benevolence in the domain of advantageous inequality is...

This paper reports the results of experiments designed to isolate the impact of various combinations of the following motives on trustworthiness: (i) unconditional other-regarding preferences - like altruism, inequality aversion, quasi-maximin, etc.; (ii) deal-responsiveness - reacting to...

We study in a sample of 1,070 primary school children, aged seven to eleven years, how altruism in a donation experiment is related to children's risk attitudes and intertemporal choices. Examining such a relationship is motivated by theories of reciprocal altruism that provide a cornerstone for...

We investigate if decision makers exploit moral wiggle room in green market settings. We therefore implement a laboratory experiment in which subjects purchase products associated with externalities. In six between-subjects treatments, we alter the availability of information on the...
