Interesting reading, although I'm always leery of relying on a single meta-analysis of a politically charged subject. For the sake of argument, though, let's take it as given that increasing the minimum wage has no or only a small effect on employment rates. Where's the money coming from, then, and what would we expect that to do to the economy?
First option: It's a free lunch; the money would otherwise go to line the pockets of (spherical, behatted, cigar-chomping) capitalists. This is implausible to me on priors, but we can put bounds on how far we can stretch it: most businesses run on margins of 15 to 20%. I'm having a slightly harder time finding figures on personnel costs, but Google informs me that 38% is a decent payroll target; factor in benefits and such and let's call it 50% for all personnel-related expenses. This suggests that minimum wage laws could increase average wages by 10 or 20% without cutting too much into business owners' cigar budgets, although we should really be thinking on the margins here.
Second option: It's being passed on to consumers in the form of higher prices. On average people are making more but also paying more; this means inflation. There are institutions trying to control inflation, though, so the costs probably end up being taken out in lower interest rates or in subtler ways. Note that higher costs of consumer goods work a lot like a mildly regressive tax; lower-income people buy more in consumer goods as a share of income.
Third option: The balance of labor changes. Jobs that can't economically be done at the lower wage points move to places that have less stringent laws, and trainable or higher-skilled jobs move in to fill the employment gaps. I don't think I'm economist enough to analyze this fully, but it looks like we'd expect wages for those higher-skilled jobs to go down in the affected jurisdiction as a consequence of supply-and-demand issues, probably after a time lag. In any case someone's still doing crappy jobs for crappy wages; they just don't show up in the statistics. Frictional costs also arise; outsourcing isn't cheap.
Fourth option: Something's masking the effect. Either the changes are slow enough that they don't show up in the available statistics, or something I haven't thought of is going on.

My first reference above was more of a "meta-meta-analysis" since it surveys the results of several meta-analyses! At a high level, it is going to be quite difficult to argue that there really is a big impact on employment, but somehow all the analyses and meta-analyses have missed it. As I said, I found it surprising, but this is the full evidence base.

Yes, politics, boo hiss. In my defense, the topic of this post cuts across usual tribal affiliations (I write it as a liberal criticizing other liberals), and has a couple strong tie-ins with main LessWrong topics:
The issue is this: recently, I've seen a meme going around to the effect that companies like Walmart that have a large number of employees on government benefits are the "real welfare queens" or somesuch, and with the implied message that all companies have a moral obligation to pay their employees enough that they don't need government benefits. (I say mention Walmart because it's the most frequently mentioned villain in this meme, but others, like McDonalds, get mentioned.)
My initial awareness of this meme came from it being all over my Facebook feed, but when I went to Google to track down examples, I found it coming out of the mouths of some fairly prominent congresscritters. For example Alan Grayson:
Or Bernie Sanders:
Now here's why this is weird: consider Grayson's claim that each Walmart employee costs the taxpayers on average $1,000. In what sense is that true? If Walmart fired those employees, it wouldn't save the taxpayers money: if anything, it would increase the strain on public services. Conversely, it's unlikely that cutting benefits would force Walmart to pay higher wages: if anything, it would make people more desperate and willing to work for low wages. (Cf. this this excellent critique of the anti-Walmart meme).
Or consider Sanders' claim that it would be better to raise the minimum wage and spend less on government benefits. He emphasizes that Walmart could take a hit in profits to pay its employees more. It's unclear to what degree that's true (see again previous link), and unclear if there's a practical way for the government to force Walmart to do that, but ignore those issues, it's worth pointing out that you could also just raise taxes on rich people generally to increase benefits for low-wage workers. The idea seems to be that morally, Walmart employees should be primarily Walmart's moral responsibility, and not so much the moral responsibility of the (the more well-off segment of) the population in general.
But the idea that employing someone gives you a general responsibility for their welfare (beyond, say, not tricking them into working for less pay or under worse conditions than you initially promised) is also very odd. It suggests that if you want to be virtuous, you should avoid hiring people, so as to keep your hands clean and avoid the moral contagion that comes with employing low wage workers. Yet such a policy doesn't actually help the people who might want jobs from you. This is not to deny that, plausibly, wealthy onwers of Walmart stock have a moral responsibility to the poor. What's implausible is that non-Walmart stock owners have significantly less responsibility to the poor.
This meme also worries me because I lean towards thinking that the minimum wage isn't a terrible policy but we'd be better off replacing it with guaranteed basic income (or an otherwise more lavish welfare state). And guaranteed basic income could be a really important policy to have as more and more jobs are replaced by automation (again see gwern if that seems crazy to you). I worry that this anti-Walmart meme could lead to an odd left-wing resistance to GBI/more lavish welfare state, since the policy would be branded as a subsidy to Walmart.
