What is the right Minimum Wage? In typical Economics fashion: "It depends"

When I am asked whether or not we should have a higher minimum wage my answer is usually something like "a wage that helps all low/no skilled workers concerned and does not harm any current or future low/no skilled workers".  Admittedly not very helpful.

I put together some slides with explanations of how I try to objectively view the issue.  There maybe a sweet spot for the minimum wage.  Where that is, well, I fall back onto "it depends".  I think that is actually the best answer.

I hope this helps someone, teacher or student.  Feel free to comment.
