Abstract
We email hotels from one of twelve fictitious email accounts (varying race, gender, and education) asking for local restaurant recommendations. We assess discrimination against email-senders by examining the quantity and quality of service provided.

Interventions

Intervention(s)
We sent emails to hotels in the US, asking for restaurant recommendations. Emails were identical except for two components: the 1) city of the recipient hotel and 2) email-sender’s name. The email “From” line and signature varied to reflect the race (white, black, Asian), gender (male, female), and social status (graduate degree, no graduate degree) of email-senders.
