This is the isoelastic utility function (https://en.wikipedia.org/wiki/Isoelastic_utility)

Value of doubling consumption according to this utility function

equals
12
Value of consumption increase

Note that consumption increases are more valuable below $258 for isoelastic utility and less valuable after $258. This is true for eta (t) > 1, and is the opposite when eta < 1. Because GiveDirectly's transfers are always smaller than doubling consumption, this means isoelastic utility values these transers more than logarithmic utility.
