The improved statistical fit using average revenue as the price variable was shown to be an artifact of the unitary elastic identity created when monthly rate schedules contain a fixed fee. When the fixed fee was purged from the data, average price was not significant, but marginal price remained significant. In the preferred double-log marginal price model, estimated price elasticity was –0.3, and conservation programs had no significant effect on water use. (JEL Q25)
