Is it safe to drink the water? Mostly yes, and more so than 20 years ago. Enjoyed talking with @davidkeiserecon.bsky.social and @margaretwalls1.bsky.social on @rff.org's Resources Radio about 266 million pollution readings, federal water loans, and costs/benefits. www.resources.org/resources-ra...

Cool new AER paper uses data from Clean Air Act offset markets to assess the efficiency of air pollution regulation. The analysis finds that marginal benefits of abatement exceed mean offset prices more than ten-fold, across most regions and pollutants.

Stunning chart from a great paper by @joseph-s-shapiro.bsky.social: the IRA’s “leasing loophole” - which let foreign-made EVs qualify for tax credits - sent US leasing numbers soaring. EU exporters were likely among the main winners - and will be among the first to feel the hit as the IRA unravels.

Funny how words shape perception. I called our research finding that repealing Inflation Reduction Act subsidies would cut EV sales by 27% 'not trivial.' Yahoo Finance called it 'massive.' Same number, opposite vibes. finance.yahoo.com/news/not-tri...

For the automotive industry, reports that President-elect Donald Trump and his team are looking to repeal the $7,500 federal tax credit are not surprising. However, the effect of a potential repeal co...

Much media interest today in how repealing electric vehicle tax credits under the Inflation Reduction Act will affect EV sales e.g. www.bloomberg.com/news/article... One estimate: 27 percent decrease in sales relative to counterfactual, from Table 5 of joseph-s-shapiro.com/research/EVT...
