Permit prices, since they would be more volatile over time than a specified tax trajectory, would mask the critical long - term signal that carbon will always be more expensive next year than it is today; that is, unavoidable volatility in permit prices would raise the economic cost of any climate target by clouding investment decisions with another source of uncertainty.

The price bounces around and that adds a little bit of uncertainty, potentially a lot of uncertainty...
