Men in same sex relationships are up to 25% less likely to secure a booking on AirBnb because of discrimination.
That's according to two Trinity economists who carried out an experiment on the holiday accommodation site.
Over 600 hosts were contacted about booking a room.
Out of four fictional couples, two gay men were 25% less likely to successfully make a booking.
However the research didn't appear show any prejudice against two women in a same sex relationship.
Co-author of the report Ronan Lyons says the discrimination wasn't put in writing, but the gay couple were more likely to have their inquiry email ignored.
