Given a poverty line, a person who is non-poor (poor) currently may not be treated as non-poor (poor) in a vulnerable situation. The poverty line is adjusted in the presence of vulnerability such that the utility of a person at the current poverty line and that at the adjusted poverty line become identical. Using an additive model of vulnerability, it is shown that if the utility function obeys constant Arrow-Pratt absolute risk aversion, then the harmonized poverty line is a simple absolute augmentation of the current poverty line.

Their findings were first published online in the Proceedings of the National Academy of Sciences on 15 April 2013.
