Abstract. In this article, we examine several techniques that allow for the construction
of bounds estimates based on instrumental variables, even when the instruments
are not valid. We introduce the plausexog and imperfectiv
commands, which implement methods described by Conley, Hansen, and Rossi (2012,
Review of Economics and Statistics 94: 260–272) and Nevo and Rosen
(2012b, Review of Economics and Statistics 94: 659–671). We
examine the performance of these bounds under a range of circumstances, which
leads to several practical results related to the informativeness of the bounds
in different situations.
