RGGI linked to lower wages for unskilled energy-sector workers

{
"What the study found": "The study found that after the Regional Greenhouse Gas Initiative (RGGI, a U.S. cap-and-trade program for greenhouse gas emissions) was implemented, annual wage income fell for unskilled workers in energy-intensive sectors. The negative effect grew over time and peaked at about a 7% reduction four years after the reform.",
"Why the authors say this matters": "The authors conclude that the findings show distributional labor market effects of RGGI, with impacts concentrated among unskilled workers in energy-intensive sectors. The study suggests the policy’s labor market effects were not uniform across worker groups or sectors.",
"What the researchers tested": "The researchers used an event-study design to examine labor market outcomes in RGGI states compared with non-RGGI states. They analyzed Current Population Survey data from 2000 to 2020.",
"What worked and what didn't": "The results show a significant and immediate decline in annual wage income for unskilled workers in energy-intensive sectors after RGGI implementation. For skilled workers, wage effects were less consistent and generally not statistically significant, although some post-treatment years showed negative point estimates. The study found no significant effects on weeks worked, unemployment probability, or outcomes for workers in non-energy-intensive sectors.",
"What to keep in mind": "The abstract does not describe specific limitations beyond the comparison of RGGI and non-RGGI states and the use of Current Population Survey data. The summary provided here is limited to the outcomes reported in the abstract."

Key points

• RGGI was associated with lower annual wage income for unskilled workers in energy-intensive sectors.
• The wage decline for unskilled workers peaked at about 7% four years after implementation.
• For skilled workers, wage effects were inconsistent and generally not statistically significant.
• The study found no significant effects on weeks worked or unemployment probability.
• No significant effects were found for workers in non-energy-intensive sectors.
