Last year, the Productivity Commission ran an event on the topic ‘Strengthening Evidence-based Policy in the Australian Federation’, of which I was one of the participants (my contribution was titled: ‘Evidence-based policy: summon the randomistas?’). The PC has now produced a mighty two-volume set, which is also available on their website. If you’re short on time, go to the background report (volume two), which is likely to become a standard reference for anyone thinking about evidence-based policy in Australia. We’ll see if George Pell gets around to reading Appendix A.
