Abstract
This study aims to explore barriers to enrollment in health insurance programs – the health insurance exchanges established by the Affordable Care Act and Medicaid - and to assess the efficacy of several interventions in raising participation rates. This project will use a mail-based randomized field experiment to evaluate the importance of several likely barriers to take-up - imperfect information, transaction costs, and behavioral biases such as limited attention and procrastination

Experimental Design Details
Please see attached.
Randomization Method
Randomization done in office by computer. See attached document for more details.
Randomization Unit
Census blocks, aggregated to at least 25 households when necessary.
Was the treatment clustered?
Yes
Experiment Characteristics
Sample size: planned number of clusters
924 adjusted Census blocks.
Sample size: planned number of observations
37,663 household addresses
Sample size (or number of clusters) by treatment arms
Target 2000 in each information treatment (A1, A2) and each salience treatment (C1, C2), and 1250 in each gift card treatment (B1, B2). Randomization process will mean some deviation from these targets.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
