Abstract
How people draw the moral circle that defines whom they include in their moral considerations, is at the heart of the most pressing policy challenges facing the world today and strongly related to the question of global fairness. Large inequalities between countries and an increasing number of migrants are pervasive features of the modern world that raise the profound question about who we are morally obligated to help. Do people perceive there to be particular moral obligations between citizens within a country and, if so, what are the constituents of these obligations? These questions are also of great importance in the climate debate, where it is essential to understand
which moral obligations people believe they have towards future generations.

The ambition of this research project is to study to what extent an important type of relationships, collaboration for mutual benefit, is seen to give rise to distributive obligations and to what extent such collaboration creates an asymmetry in the obligations that exist within and between
groups of individuals who collaborate.

Experimental Design

Experimental Design
We examine the distributive behavior of an independent third party, a spectator, who is asked to determine the distribution of income between two individuals. Both individuals have done the same assignment, but one of them has been unlucky and lost his or her earnings.

We will conduct four treatments that only differ with respect to whether or not the two individuals affected by the spectator's decision
is from the same group or not, and with respect to whether the individuals worked independently on the assignment or
whether they collaborated on the assignment with the others in their group. Our design thus allows us to compare inequality acceptance within and between groups and to study how inequality acceptance depends on whether the groups are minimal or collaborative.
