Food Aid is worth just 11% of its Cash Cost to the Poor?

That's what a study by Jesse M. Cunha, Giacomo De Giorgi, Seema Jayachandran suggests (Chris Blattman via Beata):

Both types of transfers increase the demand for normal goods, but only in-kind transfers also increase supply. Hence, in-kind transfers should lead to lower prices than cash transfers, which helps consumers at the expense of local producers.

We test and confirm this prediction using a program in Mexico that randomly assigned villages to receive boxes of food (trucked into the village), equivalently-valued cash transfers, or no transfers. The pecuniary benefit to consumers of in-kind transfers, relative to cash transfers, equals 11% of the direct transfer.
