Abstract
This study examines how people's perceptions on the governmental role of providing public goods affect their policy preferences for the government size. To this end, we conduct an online survey experiment where the information regarding the governmental role of providing public goods is randomly assigned.

Primary Outcomes

Primary Outcomes (end points)
Policy preferences for taxation and public spending
Primary Outcomes (explanation)
Policy preferences for taxation and public spending. Outcomes include preferences for the government size (e.g., whether one agrees to increase tax rates), preferences for the desirable tax system (e.g., progressive vs. uniform vs. lump-sum), and preferences for public spending (e.g., whether it should be used for helping the poor).

Secondary Outcomes

Secondary Outcomes (end points)
Manipulation check: the perception on the governmental role of providing public goods.
Another outcome: level of political trust
Secondary Outcomes (explanation)

Experimental Design

Experimental Design
We conduct an online survey experiment where the information emphasizing the governmental role of providing public goods is randomly assigned.
Experimental Design Details
We conduct an online survey experiment where the information emphasizing the governmental role of providing public goods is randomly assigned. We look at the treatment effect of this information on preferences for taxation and providing public goods.
Randomization Method
Randomization is done by a computer.
Randomization Unit
individual
Was the treatment clustered?
No

Experiment Characteristics

Sample size: planned number of clusters
one country
Sample size: planned number of observations
3000 individuals
Sample size (or number of clusters) by treatment arms
1500 individuals control, 1500 individuals treatment.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
Significance level: 5%, Power: 80% For a binary outcome where the average of the control is 0.5, the minimum detectable effect size is around 0.05 (5%).
