Simple random sampling has been assumed in most statistical inference procedures developed to test Lorenz dominance and other partial ordering conditions. This note, using the Bahadur representation, derives the (asymptotic) covariance structures of the Lorenz and generalized Lorenz ordinates...

Spatial units typically vary over many of their characteristics, introducing potential unobserved heterogeneity which invalidates commonly used homoskedasticity conditions. In the presence of unobserved heteroskedasticity, standard methods based on the (quasi-)likelihood function generally...

In recent years, the econometrics literature has shown a growing interest in the study of partially identified models … of partial identification analysis. This review introduces the fundamental tools of the theory of random sets, which … brings together elements of topology, convex geometry, and probability theory to develop a coherent mathematical framework to …
