Onions Forever! A Response to Allan Shampine
There is nothing like the provocative post from Allan Shampine to move this debate up a notch. First, I did not say that the debate over interchange fees was Onionesque. I reserved that dubious distinction to the on-the-hand-on-the-other-hand title of the GAO report. Allan is right that the stakes are huge, which is why this debate is so important. But he is wrong to think that the GAO adds much to the debate when all it can responsibly say is that any regulation of interchange fees has both costs and benefits, when it is unable to quantify or evaluate either.
