On Friday, the Environmental Protection Agency finalized the “air toxics rule” – a regulation mandating the reduction of toxic emissions (including mercury and arsenic) from the nation’s power plants, with some details concerning this rule made available to Washington Post. The EPA is expected to provide full information on the rule later this week.

The cost and other data on the final rule that have been released differ little from information available about the proposed rule.  It is thus very unlikely that the final Regulatory Impact Analysis (RIA) describing the expected impacts of the final rule will differ significantly from the proposed Regulatory Impact Analysis and other information released with the proposed rule in March of this year. This information makes clear that with benefits exceeding costs by at least 5-to-1, the rule is well worth doing – with up to 17,000 lives saved per year after its implementation and 850,000 additional days of work added to the economy because workers are healthier and would require fewer sick days.

Opponents of the act predictably characterized the air toxics rule as a “job-killer.” Even normall,y this is pretty bad economics – no serious economist thinks that regulatory changes on the scale of the air toxics rule have non-trivial impacts on national job growth. And during times like now – with the economy mired in a “liquidity trap” (very large amounts of productive slack persist even as short-term interest rates are stuck at zero) – this is completely upside-down economics. In today’s circumstances (with very high rates of unemployment) the jobs directly created by the need to install pollution abatement and control technologies will almost surely not be offset by rising interest rates or prices, as could happen if these regulations took effect in an economy with no productive slack.

Our own earlier research, based on the information provided with the proposed rule, indicated that it would lead to roughly 92,000 net new jobs by 2015. The nature of this estimate is likely to apply to the final rule as well. To be clear, this rule isn’t a significant jobs policy that would put a large dent in the current unemployment crisis. But, it is a very valuable rule that would only push in the correct direction in the labor market.

We will re-examine the job impacts of the final rule when full information is available.
