I think the BIG is an interesting idea, but I'd like to see some hard evidence that it works before we implemented something this large nationwide. The government should do a controlled test. You could go somewhere like India, randomly select a bunch of small cities, give half of them a BIG, and see what it did to work incentive and the local economy. It would only cost a few million, and you'd have better, more reliable data than economists' un-tested theories.
