In this paper we study a statistical method of implementing quasi-Bayes estimators for nonlinear and nonseparable GMM models, that is motivated by the ideas proposed in Chernozhukov and Hong (2003) and Creel and Kristensen (2011) and that combines simulation with nonparametric regression in the...

There are currently about two dozen Lorenz models available in the literature for fitting grouped income distribution data. A general method to construct parametric Lorenz models of the weighted product form is offered in this paper. First, a general result to describe the conditions for the...

We present two new Lorenz curve families by using the basic model proposed by Sarabia, Castillo and Slottje (1999). We present estimations which show that the models in our new families are very efficient when applied to data on income distribution for a range of countries from Shorrocks (1983).
