Wonky, but I assume that's your goal.
Might not hold when non-market goods or market goods with additional non-market benefits or costs are considered.
@Adam -- such as?
How about instead: Solutions that conflict with price signals lead down the path of unintended consequences
GHGs. Price higher than private marginal costs of production signals producers to produce more. Externalities not being accounted for leads to higher than socially optimal production. Solution is to produce less but price signals to produce more.
@Kristoffer -- that's longer!@Adam -- No, the goal is to produce less. What's your SOLUTION to that?
I would definitely call producing less "the solution". I think that I think that "mechanisms" is a better word to use, as in market mechanisms for example.
...so the solution is often to change the price signals, e.g., through policy...
