Cash Transfer Evaluation Design in Northern Kenya
Présenté par Marta Marzi (Oxford Policy management) - Discutant: Jérémie Gignoux (Paris School of Economics - INRA)
The Hunger safety net programme (HSNP) is an unconditional cash
transfer programme that aims to reduce poverty in northern Kenya by
delivering regular cash transfers to beneficiary households or
individuals in four counties in the arid and semi-arid lands
(ASALs) of northern Kenya: Mandera, Marsabit, Turkana and Wajir.
During the pilot phase approximately 300,000 beneficiaries (60,000
households) were targeted under three different targeting
mechanisms. A consortium led by Oxford Policy Management (OPM) has
been contracted by DFID to undertake a rigorous evaluation of the
programme’s targeting effectiveness and impact based on panel data
(around 5000 households) collected over three years between August
2009 and November 2012.
The impact of the HSNP has been assessed using rigorous scientific methods. Using a randomised controlled trial approach, a number of geographical areas (sub-locations) were randomly chosen to be assessed by the evaluation. These sub-locations were then randomly assigned to be either ‘treatment’ areas, where the programme began to operate straight away, or ‘control’ areas, in which the programme did not start for two years (the duration of the impact evaluation). The programme’s selection process was implemented (prior to the baseline survey) identically in both treatment and control areas. Impact was then assessed by comparing HSNP beneficiary households in treatment areas with households in control areas that were selected for the programme but who would not come into the programme for two years.
In the presentation I will focus on the design of the evaluation and only briefly touch upon the impact evaluation results.
