4		Consumption Increases					GW's 2020 write-up on moral weights	Our model accounts for changes in the natural log of consumption. The logarithmic model captures the idea that money has diminishing value as you get more and more of it. For example, our model considers a 50% increase in income as a little better than 50% as good as an 100% increase in income.

7		Averting deaths
8			Value assigned to averting the death of an individual under 5 from malaria	UoV	input	116	GW's analysis of moral weights for malaria
9			Value assigned to averting the death of an individual 5 or older from malaria	UoV	input	73	GW's analysis of moral weights for malaria
10			Value assigned to averting the death of a 6- to 59-month-old child (VAS)	UoV	input	119	GW's analysis of moral weights for vitamin A supplementation
11			Value assigned to averting the death of an individual under 5 from vaccine-preventable diseases	UoV	input	116		We use the same value we calculated for malaria because we have not attempted to calculate the age distribution of mortalities among children under 5 for all vaccine-preventable diseases. We would guess that this age distribution of mortalities is similar to the age distribution of mortalities for deaths caused by malaria among children under 5.
12			Value assigned to averting the death of an individual 5-14 years old from vaccine-preventable diseases	UoV	input	134	GW's analysis of moral weights for New Incentives
13			Value assigned to averting the death of an individual 15-49 years old from vaccine-preventable diseases	UoV	input	104	GW's analysis of moral weights for New Incentives
14			Value assigned to averting the death of an individual 50-74 years old from vaccine-preventable diseases	UoV	input	42	GW's analysis of moral weights for New Incentives
