Abstract

The trial is a correspondent-based audit study among Danish child care facilities. We test whether there is evidence for ethno-religious discrimination, and whether it is based on statistical discrimination. We, in exploratory analyses, will further examine discrimination in access to child cares across facilities of different ownership (public, private nonprofit, private for-profit).

Experimental Details

Interventions

Intervention(s)

The study is based on a 2-by-2 within-subjects factorial design, resulting in 4 experimental conditions to which all facilities will be exposed. Hence, it includes a set of 4 randomly ordered emails, with a wash-out period of 15 business days (3 weeks) in between. Child care faculties will be inquired about a waitlist, and additional enrollment requirements. It will be send from fictitious parents.
The first factor includes Danish sounding names versus Muslim sounding names.
The second factor provides information about the perceived costliness of the child, either indicating that it speaks well and eats all kinds of foods (i.e., no cost signal), or no such information.

Primary Outcomes

Primary Outcomes (end points)

(1) Response rate, (2) Waiting list information, (3) Additional requirements

Primary Outcomes (explanation)

(1) – Has responded (not including automated responses) within 10 business days? (yes/no)
(2) – Information about how to get on the waiting list provided? (yes/no)
(3) – Any requirements to get on the waiting list posed? (requirements related to the kindergarten and not information about general national or municipal rules) (yes/no)

Secondary Outcomes

Secondary Outcomes (end points)

Additional exploratory outcomes will be added once data is collected but results-blind

Experimental Design

All identified child care facilities, stratified by ownership type, will be send 4 emails, each representing one of the 4 experimental conditions. Email will be send to the manager of each facility. Email order will be randomized, and there will be a wash-out period of 15 business days (3 weeks) between each email.

Experiment Characteristics

Sample size: planned number of clusters

n/a

Sample size: planned number of observations

1,931 child care facilities in total (976 public, 467 private nonprofit, and 488 private for-profit). Each child care facility will receive 4 emails.

Sample size (or number of clusters) by treatment arms

Because each child care facility will be nested in 4 emails with each representing 1 of the 4 experimental conditions, each facility will be assigned to all four experimental conditions (i.e., the temporal order of emails will be randomized). Hence the number of observations per treatment arms is the same as the planned number of observations (see above).

Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
