What the study found
The study found that the Regional Greenhouse Gas Initiative (RGGI), a cap-and-trade program for greenhouse gas emissions, was associated with a decline in annual wage income for unskilled workers in energy-intensive sectors. The wage effect was immediate and grew over time, reaching about a 7% reduction four years after the policy change.
Why the authors say this matters
The authors suggest the findings show that climate policy can have uneven labor market effects across worker groups. They conclude that the results are relevant for understanding how emissions policy may affect wages in different sectors and skill levels.
What the researchers tested
The researchers used an event-study design and data from the Current Population Survey covering 2000 to 2020. They compared labor market outcomes in RGGI states with those in non-RGGI states before and after RGGI implementation.
What worked and what didn't
For unskilled workers in energy-intensive sectors, the study found a significant and immediate drop in annual wage income, with the negative effect becoming larger over time. For skilled workers, the 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 summary does not describe additional limitations beyond the comparison of RGGI and non-RGGI states and the use of Current Population Survey data. The findings are limited to the outcomes and groups reported in the abstract.
Key points
- RGGI was associated with lower annual wage income for unskilled workers in energy-intensive sectors.
- The wage decline was immediate and grew over time, peaking at about 7% four years after reform.
- Skilled workers showed less consistent wage effects, and most were 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.
