The study aims to investigate the reasons behind the low take-up rate of the Desenrola program, a debt renegotiation initiative designed for millions of lower-income individuals in Brazil. The program utilizes state guarantees to facilitate the restructuring of debts and alleviate financial burdens among the target population. The Desenrola program operates in a digital format, and the study seeks to contribute to the recent literature on the implementation of digital programs, particularly those aimed at economically vulnerable populations.

Experimental Design

Experimental Design
Our project involves two approaches aimed at understanding and addressing the low take-up rate of the digitally delivered program among lower-income individuals. The first approach is a comprehensive survey to analyze barriers hindering program access. It includes investigating issues such as a lack of information on accessing the program, difficulties with platform navigation, and a general lack of interest among potential beneficiaries. The survey will collect data on specific challenges individuals face in accessing the Desenrola program. The goal is to identify key obstacles and effectively tailor interventions to address these barriers. The second approach is an intervention targeted at a subsample of potential beneficiaries. This intervention will provide information on how to access the online platform and about guidance on procedures for viewing and accepting program offers.
