Yes. If you raise a price on something, you will get less of it. The question for me is whether it is durable. The case of Australia is a good example that if you raise the price, you get a reduction. The question is, what happens then? If the price is undone, then it is not durable. You need a durable incentive, and setting the price correctly helps ensure that durability. Looking for alternative ways that don't require a big price increase I think is the most durable.
