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 replication tests the strength of the conclusions of the original paper and confirms the main findings.
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.
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.
Maira Reimão conducted a replication of a 2011 study, Cash or condition? Evidence from a cash transfer experiment, by Baird and colleagues, which is one of the few studies that empirically compares the impact of unconditional cash transfers to that of conditional cash transfers.
