We develop a practical and novel method for inference on intersection bounds, namely bounds defined by either the infimum or supremum of a parametric or nonparametric function, or equivalently, the value of a linear programming problem with a potentially infinite constraint set.

This paper is concerned with developing uniform confidence bands for functions estimated nonparametrically with instrumental variables.

We study food Engel curves among the poor population targeted by a conditional cash transfer programme in Colombia.

We analyze how an entry regulation that imposes a mandatory educational standard affects entry into self-employment and occupational mobility.

This paper analyzss the effects of a ban on smoking in public places upon firms and consumers.

Econometric inequality hypotheses arise in diverse ways.
