Ten Lessons for Economic Policymakers*

Economists have played a powerful role in shaping modern Australia. Drawing on my experience as an academic economist and an economic policymaker, I outline ten principles to guide economists seeking to maximise their impact. These are to (i) Focus on well‐being, not just dollars; (ii) Think comparative advantage; (iii) Ignore sunk costs; (iv) Optimise, subject to constraints; (v) Use the best evidence; (vi) Consider expected value; (vii) Think in magnitudes, not just in signs; (viii) Channel a libertarian; (ix) Remember equity; and (x) Incentives matter.
