Giving and sorting among friends: Evidence from a lab-in-the-field experiment

- We examine dictator giving in a lab-in-the-field experiment in Cairo.
- Giving to a stranger and to a friend is positively correlated.
- More altruistic dictators increase their giving less under nonanonymity.
- Friends' altruistic preferences are not significantly correlated.
- Friendships may be valued differently when financial dependence on them is high.

We examine dictator giving in a lab-in-the-field experiment in Cairo. Giving to a stranger and to a friend is positively correlated, and more altruistic dictators increase their giving less under non-anonymity. However, friends' altruistic preferences are not significantly correlated.
