Editing Mere addition paradox (section)

==Alternative usage==
An alternative use of the term ''mere addition paradox'' was presented in a paper by Hassoun in 2010.<ref>{{cite book |url=http://www.wider.unu.edu/publications/working-papers/2010/en_GB/wp2010-120/ |title=Another Mere Addition Paradox? Some Reflections on Variable Population Poverty Measurement |publisher=UNU-WIDER |date=November 2010 |accessdate=31 March 2015 |isbn=978-92-9230-358-7}}</ref> It identifies paradoxical reasoning that occurs when certain statistical measures are used to calculate results over a population. For example, if a group of 100 people together control $100 worth of resources, the average wealth per capita is $1. If a single rich person then arrives with 1 million dollars, then the total group of 101 people controls $1,000,100, making average wealth per capita $9,901, implying a drastic shift away from poverty even though nothing has changed for the original 100 people. Hassoun defines a ''no mere addition axiom'' to be used for judging such statistical measures: "merely adding a rich person to a population should not decrease poverty" (although acknowledging that in actual practice adding rich people to a population may provide some benefit to the whole population).
