There is obviously an economic impact from not paying workers a living wage, irrespective of how certain arguments can be parsed. There is also obviously an economic cost associated with paying a living wage.
The alternatives to the minimum wage that you listed are pretty much variations on the mimimum wage in that they seek to achieve the same goals and also have attendant costs. They are, essentially, no more or less moral vs. economic in nature than is the minimum wage, though their invocation may be less charged at present.
The latter point is evidenced by your juxtaposition of the "moral" minimum wage with its presumably amoral (and thus economics-based) alternatives. But, in truth, if any of these have valid economic arguments, then so does the minimum wage.
