This replication study re-examines some of the limited existing research on how quality of housing affects health and socioeconomic outcomes, including household measures of health for children and mothers. The replication researchers, María Pía Basurto, Ramiro Burga, José Luis Flor Toro and César Huaroto, reproduce the published findings in their pure replication. They then extend their analysis to explore alternative definitions and measurement strategies in their measurement and estimation analysis (MEA) and look at possible heterogeneous impacts in their theory of change analysis (TCA).
The original study, Housing, Health and Happiness by Cattaneo et al. (2009), is a quasi-experimental impact evaluation of Piso Firme, a government intervention to replace dirt floors with cement flooring in Mexican households. The replication researchers find very similar results as the original study in their pure replication, with the introduction of cement floors increasing health measurements in both children and adults. The results remain generally robust to the alternative strategies introduced in the MEA. In their TCA results, the replication researchers found that households with initial high levels of cement floor coverage benefited less from this intervention than those with lower level of cement flooring at the beginning of the intervention.
The authors of this paper replicated a landmark study by Hayes and colleagues (2019) on the HPTN 071 (PoPART) trial, which examined if a universal test and treatment program, along with a combination prevention intervention, could reduce HIV incidence in Zambia and South Africa.
Eric Djimeu and Eleanor G Dickens conduct a replication of the HPTN 052 study by Cohen and colleagues that evaluates the impact of early initiation of antiretroviral therapy on rates of sexual transmission of HIV-1.
The National Rural Employment Guarantee Scheme and Social Security Pension are two of the largest employment programmes in Andhra Pradesh. Muralidharan and colleagues (2016) investigated the impacts of biometrically-authenticated payment infrastructure (Smartcards) on beneficiaries of the two employment programmes.
This replication study starts with the twin strategies of push-button and pure replications of the original study. It then followed this up with various consistency and
robustness checks, such as propensity score matching and the Tobit model specification.
