I'm hoping those two things are not the same to you, or to your readers; else you are all part of why our profession is less like chemistry, more like alchemy.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7464708.post-11597061023879341372015-10-03T11:38:09.219-04:002015-10-03T11:38:09.219-04:00Thank you for absolving me.

I was wondering why some professors insist their students use it. I have read a lot about it, and my take away is that IV is a neat idea (or method), but rarely useful in practice. Thank you for taking such a strong stance. We, graduate students often want to hear dissenting opinions.sbikhttps://www.blogger.com/profile/04145436991903927426noreply@blogger.comtag:blogger.com,1999:blog-7464708.post-8993321268248403032015-10-03T09:00:40.478-04:002015-10-03T09:00:40.478-04:00There are tests for instruments when the endogenou...There are tests for instruments when the endogenous X is discrete, see https://en.wikipedia.org/wiki/Instrumental_variable#Non-parametric_analysisJulian Schuesslernoreply@blogger.comtag:blogger.com,1999:blog-7464708.post-32798479433969742262015-09-30T14:02:27.693-04:002015-09-30T14:02:27.693-04:00This problem is only going to get worse.
