Abstract
Low-income households in the Philippines lack sufficient access to affordable and resilient housing to protect them from the physical and economic damages brought by increasingly frequent extreme weather events, such as typhoons and floods. We partner with a large microfinance NGO and an NGO focused on housing for low-income households, to evaluate a new housing microfinance product. We will run a 2x2 randomized evaluation that cross-randomizes a high-touch education component (versus no education) and the new housing loan terms (versus being offered the old housing loan terms), against a control group. The main outcomes are short-term impacts on perceptions of climate risk and resilience, knowledge and plans for house construction, and other measures of resilience. The study will create new knowledge about how to support low-income households in obtaining housing that is resilient to extreme weather events, which is relevant across a number of developing countries that are vulnerable to climate change.

Randomization is at the microfinance client-group level (954), stratified by branch (12), by loan officer (70).
Was the treatment clustered?
Yes

Experiment Characteristics

Sample size: planned number of clusters
954 microfinance client groups, stratified across 12 MFI branches and 70 loan officers.
Sample size: planned number of observations
There are 22,244 clients divided across 954 microfinance client groups, stratified across 12 MFI branches and 70 loan officers. We will attempt to collect the mini-survey and administrative data from as many clients as will consent. For more details on this, and the endline survey sampling, please see the attached analysis plan.
Sample size (or number of clusters) by treatment arms
Each treatment arm, and the control, have about 190 clients groups. For more details on this, and the allocation of endline surveys to treatment arms, please see the attached analysis plan.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
Please see the attached analysis plan.
