| Jun 5, 2012 at 20:45 | comment | added | Stephan Sturm | As you may assume wlog '$U(\infty)>0$', it should follow directly from the asymptotic elasicity condition (2), no? As this inequality holds for $x$ sufficiently large, you can just separate the domain of integration and use for the second part the inequality... | |
