The control function approach which employs an instrumental variable excluded from the
outcome equation is a very common solution to deal with the problem of endogeneity in …

Control variables provide an important means of controlling for endogeneity in econometric
models with nonseparable and/or multidimensional heterogeneity. We allow for discrete …

This paper studies a class of linear panel models with random coefficients. We do not restrict
the joint distribution of the time-invariant unobserved heterogeneity and the covariates. We …

The first three chapters of this thesis study some random coefficients models. The third
chapter, being also a data combination problem, draws the link with the fourth one. The fifth …

Abstract Models with a discrete endogenous variable and an instrument that takes on fewer
values are common in economics. This paper presents a new method that matches pairs of …
