FuelWatch: evidence-based-policy or policy based evidence?

Abstract

Experience from the United Kingdom and the United States suggests that expert evidence is often reshaped and repackaged by governments so that it supports existing policy rather than informing policy decisions. The Australian government based its decision to introduce FuelWatch on evidence in the form of econometric work by the ACCC. This paper asks two questions about that decision. First, was the policy shaped by the economet- ric evidence or was the government�s presentation of the evidence shaped by the pre-determined policy? Second, is the econometric evidence sufficiently robust as to support the FuelWatch policy? I find that some of the facts suggest that evidence was reshaped and repackaged to support the FuelWatch policy. I also find that the ACCC analysis was not robust. Specifically, they study the nominal retail margin when economic theory suggests that analysis should focus on the real retail margin to producers. Using data digitized from a graph in the ACCC report I redo the econometric analysis and find that the evidence no longer unambiguously supports the FuelWatch policy. The ACCC claim that their analysis is robust because it has been subject to scrutiny within the ACCC and by Treasury but such claims of robustness cannot be verified because they refuse to release the data for public scrutiny. Publication of data and analysis underpinning government decisions and independent review of econometric work provides a more credible evidence base for future policy decisions.
