This might be an odd question, but maybe someone here can help.
I remember a quote, I think it was in the Garrison, Noreen, and Brewer text on managerial accounting. It was an executive of some company explaining that they've assumed a certain carbon tax will be imposed in the future, and they use that number in their planning. He acknowledges that the number is a guess, and will be wrong, but says that other companies who assume no carbon tax will be more wrong.
But I can't seem to find it. Does that sound familiar to anyone?
