From Vivian
Hoffmann of Cornell University, via Tom Foster:
This paper reports results from a field experiment in Uganda. Whether a mosquito
net was purchased or received for free affected who within the household used
the net. Free nets were more likely to be allocated to those members of the
household most vulnerable to malaria, whereas purchased nets tended to be
used by the household’s main income earners. The effect was strongest for
free nets received by the mother, increasing the probability that all children
five and younger slept under nets by 26 percent relative to when nets had
been purchased by either parent or given to the father.
