This thesis contributes to the scientific and policy debate surrounding the so-called graduation approach Γ’
an integrated development intervention that directly targets the poorest households in low-income countries
and provides them with a combination of assets at no cost. Though the components vary, they always
involve transfers (of a productive and/or monetary asset) alongside extended training and coaching
activities (intended to cultivate some intangible asset).
Randomized evaluations of the graduation approach have demonstrated poverty reduction across contexts
and in the long run. This has attracted policy attention, as training and coaching interventions could be
expanded in widespread social protection schemes that already identify low-income households and
provide them with cash transfers. The case for scaling up these intangible extensions could be strengthened
through a better understanding of whether and why the integrated approach is more cost-effective than its
constituent components, such as transfers alone.
Gaps also remain in the science of implementation. Past evaluations have been conducted mainly in
nonprofit pilot settings and may not be predictive of the at-scale effects that will materialize in the
institutional contexts of governments. Anticipating that the fidelity and impact of the intangible extensions
will tend to suffer with scale, we evaluate two innovations to protect implementation quality. One involves
the attempt to identify the most critical ingredients: all else equal, a simpler approach will be more scalable.
The other innovation involves the design of the funding agreements: when funders pay implementers as a
function of demonstrated impact, scale-up efforts will tend to accelerate where the critical success factors
happen to be in place.
We add to recent evidence underlining the potential of the integrated graduation approach. We find that it
tends to resist simplification attempts. Paying implementers as a function of demonstrated poverty impacts
comes with complications, but some of these are mitigated with scale.</p
