Key findings

  • In their initial benefit–cost analysis of the 2012–2016 standards, the agencies did not account for consumer or manufacturer behavioral responses to low gasoline prices.
  • We augment the agencies' benefit–cost framework and use recent evidence on behavior and gasoline prices to estimate the effects of low gasoline prices on benefits and costs.
  • The 25 percent reduction in future gasoline prices reduces the value of fuel savings by 22 percent, allowing for consumer changes in miles traveled and vehicle choice.
  • Lower gasoline prices raise compliance costs by about $0.5 billion per year, or about 9 percent of the total net benefits of the program.
  • Accounting for these responses does not overturn the agencies' initial conclusions that benefits exceed costs.
