The idea of a basic income - it's generally referred to as a Guaranteed Annual Income in Canada - has been floated again. My initial reaction was that this is such a good idea that it's hard to figure out why we don't have it already.
For some reason, there doesn't seem to much in the way of a formal modeling exercises that work through the general equilibrium implications of a BI (I will be happy to be corrected on this point), so I decided to set up a blog-sized version. It turns out that although the BI is still a good idea, it's not quite the slam-dunk I thought it was.
The gory details are below the fold.
