I was pleased to learn from a new Productivity Commission report on Regulatory Impact Analysis that the new Queensland Office of Best Practice Regulation is intending to require the publication of all final regulation impact statements (RISs), which for some odd reason we now call regulatory assessment statements (RASs) (see p. 221). This will be a large improvement on the historical record, as revealed by this chart from the Commission’s report:

Obviously publication of RISs is important so the public can judge the merits of studies informing Government decision making.
