Abstract
This project examines a government form that is used to apply for an income support payment. BETA has conducted user testing and reviewed existing literature in order to draft updates to the form. This survey experiment will evaluate how the updates to the form influence the allocation of the payment. We will compare the existing form with two ‘active choice’ treatment conditions. The efficacy of the updated forms will be judged by how much of the payment participants allocate to one member of a (fictional) couple. BETA’s survey experiment will sit in a broader survey being run by a university for a government agency. Findings from this research will be shared with relevant government agencies to guide future updates to the form. Findings will also be published on the BETA website.

Experimental Details

Interventions

Intervention(s)
This survey experiment has been designed as a stratified 3-arm randomised controlled trial (RCT). We will be simulating the decision of how to divide up a government payment between two people. This design includes one control group and two interventions:
1. Control
The control condition will simulate the current income support application form.
2. Active choice
In this condition, participants will be required to make an active choice when deciding how they want to divide their income support payment. The active choice condition aims to make the choice architecture surrounding the payment allocation question as neutral as possible.
3. Active choice + extra information
In this condition, participants will be presented with the active choice condition, as described above, as well as information on the benefits of dividing the payment more equally.

Experiment Characteristics

Sample size: planned number of clusters
N/A
Sample size: planned number of observations
1500
Sample size (or number of clusters) by treatment arms
around 500 per arm
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
The experiment will have 95% power to detect a difference of 2 days, when comparing each treatment condition to the control condition separately.
