Red = high endowment and high productivity (HH), light grey = low endowment and high productivity (LH), dark grey = high endowment and low productivity (HL), blue = low endowment and low productivity (LL). a The most popular partners (i.e., ranked as first choice) were types assigned a high endowment and a high productivity (HH) – left panel. Participants assigned a low endowment and a low productivity (LL) had the highest likelihood to not get paired with their preferred partner type (measure of rejection – right panel). b Time trend showing the development of participants’ partner type preferences (first choices), depicted separately for each participant type.
