In the article, they say that the Ghana experiment includes a comparison to a pure cash transfer (although I'm not sure of the amount of the transfer), and "the results are forthcoming." > These positive results leave us with a number of important questions. First, is it better to deliver physical assets and support, rather than pure cash transfers? There is evidence—from an RCT evaluation of the GiveDirectly program in Kenya, which transferred on average PPP US$720 to poor households, either monthly or in one lump sum—that pure cash transfers also have positive impacts on consumption, food security, asset holdings in the short run (including productive assets), and on psychological well-being (49). Similarly, de Mel et al. (50) find that a cash (or in-kind) transfer to existing self-employed individuals in Sri Lanka has a persistent positive effect on self-employment profits 4.5 to 5.5 years later. Because it is cheaper and easier to just deliver cash rather than physical assets and training, and the initial consumption increases from Kenya seem to be higher than what we observe after 2 and 3 years, it would be useful to have a direct comparison of the effects of these programs. The Ghana experimental design does include a comparison of the Graduation program to merely an asset transfer, and the results are forthcoming. > ... > Second, how important was the training and coaching as a component in the full intervention? This is a particularly important component to test, because its costs are on average twice that of the direct transfer costs, and because operating at scale requires quality hiring, training, and staff supervision. As discussed above, we do not have experimental variation with which to test this question. Evidence from elsewhere suggests that the household visits, which are a large expenditure, may not be a cost-effective component. In Blattman et al. (33), for example, variation between zero and five household visits did not generate, after 9 months, large differences in income outcomes (but did lead to higher investment). Furthermore, a meta-analysis of self-employment training programs has found mixed but rarely transformative impacts from training (51). |
