> It controls for most things. I am not suggesting the results are one way or the other, but let's all keep in mind that given any statistical phenomenon, we can control for the change. i.e. if there is an increase in automation due to the minimum wage, which in turn displaces workers, a biased or naive researcher can "control for automation and technology trends"-- effectively eliminating the perceived effect of the price floor. I'm not saying that this is what is happening here, as I haven't read the studies, but I wouldn't be surprised if this were the case given that they are claiming the law of demand doesn't apply.
