Abstract
This survey experiment will study whether presenting vignettes on China’s rising aid presence in the Pacific changes views about aid policy in Australia (currently the major donor country to the region).

Experimental Details
Interventions
Intervention(s)
In addition to the control group, two types of ‘information interventions’ will be provided in the survey experiment.

(T1) The ‘just the facts’ treatment group – that will receive a factually-accurate vignette on China’s rise as an aid donor to the region, in which facts are accompanied by matter of fact commentary.

(T2) The ‘emphasis’ treatment group – that will receive a factually accurate vignette on China’s rise in the region, which presents facts and commentary in a manner designed to place heightened emphasis on China’s rise and the risks it brings.

Primary Outcomes
Primary Outcomes (end points)
There are three main outcomes of interest. These are:
1) Desire for level of Australian aid spending to be changed.
2) What the purpose of Australian aid should be (helping developing countries or advancing Australia’s interests).
3) Whether Australian aid to the Pacific should increase as a share of Australian aid spending.

Experimental Design
Experimental Design
The effect of China’s increased aid presence in the Pacific on Australians’ views about aid will be evaluated via an online survey of a nationally representative (on age and gender) sample of the Australian population.

Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
Power calculations have been conducted to estimate the sample size required based upon the average effect size and treatment group size of similar studies on this topic (e.g. Hoy & Wood (2018)). The minimum detectable effect size on the primary question of interest (Desire for level of aid spending to be changed) is around 7 percentage points (with power 0.8 and alpha 0.05) with a sample size of 667 individuals in each group.
