Revisiting a functional form for the Lorenz curve

In a recent paper Rohde (2009) proposes a new functional form for estimating the Lorenz curve. This paper demonstrates that the model proposed by Rohde is a reparameterization of the model proposed by Aggarwal (1984). New and important properties of the model are established.
