Experimental Design (Public)

Before
We use a non-matched pair randomized controlled trial (correspondence test, between-subjects design) to test for ethnic discrimination in the shared housing market in Germany. To do so, we randomly vary the name of the applicant, which signals an ethnic minority or ethnic majority. The ethnic minority (majority) is signaled by the most average (in terms of callbacks) Turkish-(German-)sounding male name from the previous study (see AEARCTR-0007627). In addition, we create four social media profiles, two with additional information signaling cultural identification and religious beliefs, which address typical Turkish stereotypes (as held by the ethnic majority), and two without (Turkish) stereotypical images, representing an average student social media profile from the previous study. The submitted applications are similar in all aspects except for the parts that (a) signal the applicant's ethnicity, (b) whether it contains a link to the social media profile, and (c) the content of the profile (2x3 design).

After
We use a non-matched pair randomized controlled trial (correspondence test, between-subjects design) to test for ethnic discrimination in the shared housing market in Germany. To do so, we randomly vary the name of the applicant, which signals an ethnic minority or ethnic majority. The ethnic minority (majority) is signaled by the most average (in terms of callbacks) Turkish-(German-)sounding male name from the previous study (see AEARCTR-0007627). In addition, we create four social media profiles, two with additional information signaling cultural identification and religious beliefs, which address typical Turkish stereotypes (as held by the ethnic majority), and two without (Turkish) stereotypical images, representing an average student social media profile from the previous study. The submitted applications are similar in all aspects except for the parts that (a) signal the applicant's ethnicity, (b) whether it contains a link to the social media profile, and (c) the content of the profile (2x3 design).
Update (2023-10-27): Due to a design change on the platform during the trial, we add another variation with paid premium accounts that increase the visibility of applications from premium users. Thus, in addition to randomly varying (a) ethnicity, (b) social media profile link, (c) social media profile content (with/without Turkish stereotypical images), (d) we randomly vary whether the application is sent from a premium account (2x2x3 design). With this, we aim to investigate how increased visibility of applications (due to the platform design change) affects callback rates by ethnicity, and how providing additional information (social media*with/without Turkish stereotypical images) moderates this effect – compared to applications from non-premium users with lower visibility.

Planned Number of Observations
|
Before
3,500-4,000
|
After
3,500-4,000 (Update (2023-10-27): Due to a platform design change, we add another variation (premium/non-premium) and increase the number of planned observations by roughly 800-1,200.)
