THE IMPACT OF UTILITY DEREGULATION IN ARIZONA

This analysis assesses Arizona's short-run price response to utility energy deregulation in the commercial and industrial sectors and the long-term response to deregulated industrial utility prices. Using a standard utility industry approach, ordinary least squares regression confirms commercial/industrial utility prices remain inelastic and Arizona's deregulation efforts have not effectively promoted short-run price competition. Moreover, widening differences in utility rates could be a response to a stronger long-run price elastic effect across states. The findings suggest states not aggressively deregulating utility price to narrow artificial comparative price advantages could be at a competitive disadvantage for interstate manufacturing investment.
