      abstract = {Wholesale petrol prices were deregulated in August 1998.  This paper will quantify the
effect associated with the  deregulation of wholesale petrol prices on relative  retail
prices for unleaded petrol in Adelaide, Melbourne  and Sydney. This is done through
Box–Jenkins autoregressive  integrated moving average methodology coupled with
Box and  Tiao intervention analysis. Weekly price data will be used  for Adelaide,
Melbourne, and Sydney. It finds that from the  beginning of 1999, deregulation
coincided with relatively  lower retail petrol prices for all three cities. In the  absence of
any other possible alternative explanation for  the simultaneous fall in relative retail
petrol prices  across all three cities, it is concluded that this change  was most likely
associated with deregulation. These results  suggest that regulation of wholesale petrol
prices were  ineffectual in terms of constraining capital city retail  petrol prices at the
very least and may have actually  contributed towards relatively higher retail petrol
prices.  This also suggests that future policy interventions  designed to constrain prices
in the downstream petroleum  industry should be very carefully considered.},
