Abstract
|
Before
In recent years, individuals began producing air quality data (AQD) by purchasing and using air quality sensors. At a low cost to adopters, this technology can inform individual decision-making (e.g. air pollution adaptations) with real-time AQD and contribute AQD to publicly available maps. Recent research shows that socioeconomic status predicts air quality sensor adoption, potentially exacerbating existing spatial inequalities in AQD and health damages from air pollution. However, willingness to pay for this technology and its usage patterns are not yet well understood, in particular among different socioeconomic groups. We conduct a field experiment in a socioeconomically heterogeneous, high pollution setting in the United States to evaluate the adoption and use of low-cost air quality sensors.

Experimental Design (Public)
|
Before
We conduct a field study that randomly assigns households to three treatments: 1) willingness to pay elicitation type, 2) sensor offer, and 3) financial sensor use incentives.
|
After
We conduct a field study that randomly assigns households to two treatments: 1) willingness to pay elicitation type and 2) sensor offer price.

Randomization Unit
|
Before
We randomize at the individual level (WTP elicitation type and offers) and at the price group level (incentives).
|
After
We randomize at the individual level (WTP elicitation type and offer level).
