Abstract
The Fair Housing Act, through Department of Housing and Urban Development (HUD), “prohibits discrimination in housing because of: race, color, national origin, religion, sex, familial status, [and] disability.” This list notably excludes gender identity, to the extent that such identity is not inherent to “sex.” Using a well-worn correspondence methodology with a novel treatment, this study aims to identify how market behavior is affected by (a) the decision to disclose one's gender identity, and (b) whether the disclosed gender identity matches the individual's biological (chromosomal) sex.

Primary Outcomes

Primary Outcomes (end points)
Identify feelings with regards to explicitly stated gender identity and trans people.
Primary Outcomes (explanation)
"Feelings" (as used above) are proxied by the average willingness of landlords to invite applicants to the next stage of the rental process, when the unit being rented is an ADU located on their property. These types of units are being specifically selected due to their intimacy with either the landlord (should they live in the "main house" on the property) or with another tenant (should the "main house" also be rented). As such, this study will not identify (nor does it aim to identify) the typical experiences of people in the housing market, but rather the willingness of landlords to accept certain people into such "intimate" living arrangements.

Experimental Design

Experimental Design
A correspondence study in a subset of the California rental housing market (the market for rental ADUs).
Experimental Design Details
Not available
Randomization Method
Control and treatment are randomly assigned by computer (rando number generator within Google Sheets).
Randomization Unit
ADU apartment listings.
Was the treatment clustered?
No

Experiment Characteristics

Sample size: planned number of clusters
At least 600 ADU listings
Sample size: planned number of observations
At least 600 ADU listings
Sample size (or number of clusters) by treatment arms
At least 200 for the control, and at least 200 for each of the 2 treatments (so at least 600). Should the sample size grow beyond 600, given that treatment and control are assigned randomly, it is expected to grow proportionately (i.e. 1/3 control, 1/3 treatment 1, 1/3 treatment 2).
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
Response rates are the key outcome variable and are measured as a % of landlords responding to applicants within a given treatment or control. Based upon previous literature, the expected response rate will be somewhere between 60% and 80%. There is little precedent on which to base expected differences in this outcome variable for this particular treatment, so I'll run through a few power calculations (where p1 = response rate to the control group, delta = difference in response rate between control and treatment, assuming alpha = 0.05, power = 0.80, n_control = 200, and n_treatment = 200) [1] If p1 = 0.80, minimum detectable delta = 0.123 [2] If p1 = 0.75, minimum detectable delta = 0.130 [3] if P1 = 0.70, minimum detectable delta = 0.135 [4] if p1 = 0.65, minimum detectable delta = 0.138 [5] if p1 = 0.60, minimum detectable delta = 0.14
