In our paper with Tony Shorrocks (http://www.citeulike.org/user/ctacmo/article/86251), we assumed the distributions were lognormal. That way, you can find all the inequality measures (as functions of the variance of logs), and poverty measures are some normal cdfs or other relatively simple functions. Generally it's rather hard to come up with meaningful ways to play with distributions... especially if you want to control for both inequality and the mean.
