Our policy question is: when is it optimal for an organization such as Give Directly to transfer money to recipients as soon as possible, and when is it better to delay giving some of the money until the recipients experience an adverse event causing a loss of income.
We've found this paper, but it only has aggregated mean/variance quantities across households and only one type of shock. Any pointers would be appreciated!
Thank you for the comment, I learned a lot from it. Would appreciate to hear what you think about my responses.
I think the first point about consumption smoothing is critical. My reading of the literature is almost the opposite - that although the poor find ingenious ways to save, their ability to smooth consumption is very limited. I wonder why that is. Maybe it's because Portfolios of the Poor focuses on Bangladesh, India and South Africa which are much more developer financially than some other countries. But we will need to think about this some more.
The point about debt is very important and well taken. We will need to consider not just income but wealth more generally. I've corrected the question.
Regarding idiosyncratic shocks, our thought was that family level income/consumption/wealth data allows us to measure the frequency of idiosyncratic shocks. In addition, an Organization like GiveDirectly must in any case have direct communication with potential recipients to be able to transfer the money, which implies family illness may be observed.
Regarding systematic shocks, out thought was that it is easier for the donor to convert cash to goods than for the affected people. So if what they need in a drought is grain and not cash, the donor could accommodate this quite easily.
