Participants are asked to write about a memory, half about a nostalgic and half about a neutral one. Then, they played the dictator game, where they have to choose how much money to give to a receiver.
Partipants who recalled a nostagic memory gave away more money tahn those who recalled a neutral one.
Feelings of nostalgia increase our willingness to spend money.
