Great point, the leakage issue is indeed important. I am not sure that all the assessed studies include ‘well-functioning’ programs, especially since some were newly-established. But besides that, with cash you definitely don't need to manage and organize a supply chain, fair enough. Yet there are counterarguments to your legitimate points. For example, one should not assume that cash transfer schemes may be immune or less prone to leakages – that depends very much on how such programs are set-up, the infrastructure underpinning them, and local administrative capacity. Also, the use of technology to enhance accountability throughout food supply chains may reduce the leakages you mentioned: how much they would do so, and how would that compare against cash transfers, is an empirical question worth exploring. So there may be at least as much scope to improving an existing program as there is to considering alternatives. The point is that the use of cash transfers could well be a more efficient solution, but this should be the outcome of an informed discussion around why leakages exist, where they exist, and how to address them, including considering ways to improve available modalities versus replacing them (by the way, one may also consider vouchers...). Cash transfers may not be a panacea for leakages – ‘how’ transfers are managed is key, not necessarily ‘what’ is provided.
