Abstract
Environmental policies have disparate effects on household well-being, pollution, and other socially important outcomes. This study investigates beliefs about and support for the choice of environmental policies and
policy instruments, considering their objective and subjective properties.

Primary Outcomes

Primary Outcomes (end points)
* Support of different policy instrument
* Perceived effect of different instruments
Primary Outcomes (explanation)
We will estimate support based on whether participants say they support a policy, based on the participants' ranking of the policies, and based on the stated environmental goal participants prefer for each policy

We will estimate the effect of each policy instrument on perceived electricity costs and inequality

Secondary Outcomes

Secondary Outcomes (end points)
Secondary Outcomes (explanation)

Experimental Design

Experimental Design
We will estimate how interventions teaching basic economic principles affect support for different environmental policy instruments.
Experimental Design Details
