Agricultural Economics—Without Apology
My article titled “On the Measurement of Food Waste,” written with University of Minnesota colleagues Metin Çakir, Hikaru Hanawa Peterson, Lindsey Novak, and Jeta Rudi became available online a few weeks ago as an advanced access article on the American Journal of Agricultural Economics website.
Since I was traveling then, I didn’t get much of a chance to sit down and blog about it, but here goes.
In case you missed my earlier posts on the topic, here is the abstract:
Back in January, I wrote two posts about dealing with imperfect instruments. One went over Conley et al. (2012), which deals with instruments that the authors deem plausibly exogenous; the other went over Nevo and Rosen (2012), which deals with instruments that the authors deem imperfect.
In a new working paper, Damian Clarke and Benjamin Matta discuss both methods, and they present the Stata commands –plausexog– and –imperfectiv– they created to implement them.
If you are dealing with an instrumental variable that can sort of, kind of meet the exclusion restriction but might not (in other words, almost any observational IV), I suggest checking out their working paper and, if you use Stata, the add-on commands they wrote.
