designed an experiment in the city of
designed an experiment in the city of Chandigarh in 2010 and
and there were three components to this
and there were three components to this experiment the first component was a

don’t increase the fluid intake in their children when their child has diarrhea
children when their child has diarrhea
children when their child has diarrhea this is against the recommendation of
this is against the recommendation of
this is against the recommendation of the World Health Organization so we
the World Health Organization so we
the World Health Organization so we designed a recipe book in collaboration
designed a recipe book in collaboration
designed a recipe book in collaboration with the local food and nutrition board
with the local food and nutrition board
with the local food and nutrition board that contained 10 simple easy to make
that contained 10 simple easy to make
that contained 10 simple easy to make nutritious delicious calorific recipes
nutritious delicious calorific recipes
nutritious delicious calorific recipes all of them contained local ingredients
all of them contained local ingredients
all of them contained local ingredients and we said that what if we just give
and we said that what if we just give
and we said that what if we just give this to the mothers this would solve the
this to the mothers this would solve the
this to the mothers this would solve the maternal knowledge problem hopefully and
maternal knowledge problem hopefully and
maternal knowledge problem hopefully and that could improve the health of the
that could improve the health of the
that could improve the health of the kids now remember that the mother had
kids now remember that the mother had
kids now remember that the mother had blamed the state so we had to also think
blamed the state so we had to also think
blamed the state so we had to also think about ways to motivate the worker and

when we had spoken with the workers
when we had spoken with the workers workers were obviously they they were
workers were obviously they they were

not satisfied with their wages they
not satisfied with their wages they wanted their wages to go up for the
wanted their wages to go up for the
wanted their wages to go up for the amount of work that they were putting in
amount of work that they were putting in
amount of work that they were putting in so we thought of an incentive scheme
so we thought of an incentive scheme
so we thought of an incentive scheme wherein the worker would get a

wherein the worker would get a performance-based bonus and the
performance-based bonus and the
performance-based bonus and the performance would be based on the
performance would be based on the
performance would be based on the decline in malnutrition that would
decline in malnutrition that would
decline in malnutrition that would happen in her Center so she would get
happen in her Center so she would get
happen in her Center so she would get three dollars for every child that
three dollars for every child that
three dollars for every child that improved a grade of malnutrition so if a
improved a grade of malnutrition so if a
improved a grade of malnutrition so if a child went from severely malnourished to
child went from severely malnourished to
child went from severely malnourished to moderately malnourished that’s one great
moderately malnourished that’s one great
moderately malnourished that’s one great improvement or from moderate to mild
improvement or from moderate to mild
improvement or from moderate to mild that’s another great improvement so the
that’s another great improvement so the
that’s another great improvement so the worker would get three dollars for
worker would get three dollars for
worker would get three dollars for nutritional great improvements and then
nutritional great improvements and then
nutritional great improvements and then we’d also subtract from the total bonus
we’d also subtract from the total bonus
we’d also subtract from the total bonus if there were kids who declined in the
if there were kids who declined in the
if there were kids who declined in the nutritional status so for instance if
nutritional status so for instance if
nutritional status so for instance if three kids went up and one kid went down
three kids went up and one kid went down
three kids went up and one kid went down then the total payout to the worker
then the total payout to the worker
then the total payout to the worker would be six dollars 4101 children were

spend a dollar today on implementing the combined treatment over a long enough
combined treatment over a long enough

governments and NGOs
governments and NGOs and communities to actually implement
and communities to actually implement
and communities to actually implement policies that have high benefit cost
policies that have high benefit cost
