Carbon Rollercoaster: A Historical Analysis of Decarbonization in the United States
Abstract:
This paper documents the evolution of US carbon emissions and discusses the main factors that contributed to the historical carbon emissions rollercoaster. We divide the discussion into four periods – up to 1920, 1920-1960, 1960-2005 and after 2005. For each period, we discuss the main drivers of national carbon emissions. We then discuss trends in carbon emissions in the electricity sector. Electricity sector emissions were initially very small, but would become the largest source of US carbon emissions over the period 1980-2015, and the largest contributor to decarbonization since 2007. In the final section, we distill lessons from the U.S. experience that may inform decarbonization strategies in developing economies.

Extreme Temperatures and Non-Work at Work
Abstract:
Understanding the determinants of worker effort is central, as even small changes in productivity can have significant implications for economic growth and labor market performance. This study examines the relationship between extreme temperatures and work effort—proxied by non-work time while at the workplace—using the ATUS 2003–2019. Results indicate that extremely hot days (? 100ºF) are related to increased time spent at work not working, particularly among women in non-supervised occupations. On these days, women in non-supervised occupations spend 6.79 more minutes at work not working compared to comfortable temperature days. Men, by contrast, do not exhibit significant changes in non-work time at work. Furthermore, the results align with increased worker bargaining power during economic expansions, which facilitates labor supply adjustments on extremely hot days, and with hypotheses regarding adaptation and acclimation to high temperatures in warmer counties. These find ings underscore the relevance of temperature as a determinant of worker effort, reveal a previously overlooked margin of labor adjustment, and highlight the moderating role of occupational supervision in shaping behavioral responses to environmental stressors.

The Social Lifecycle Impacts of Power Plant Siting in the Historical United States
Abstract:
This paper examines the relative contributions of siting decisions and post-siting demographic shifts to current disparities in exposure to polluting fossil-fuel plants in the United States. Our analysis leverages newly digitized data on power plant siting and operations from 1900-2020, combined with spatially resolved demographics and population data from the U.S Census from 1870-2020. We find little evidence that fossil-fuel plants were disproportionately sited in counties with higher Black population shares on average. However, event study estimates indicate that Black population share grows in the decades after the first fossil-fuel plant is built in a county, with average increases in Black population share of 4 percentage points in the 50-70 years after first siting. These long-run demographic shifts are driven by counties that first hosted a fossil-fuel plant between 1900-1949. We close by exploring how these long-run demographic shifts were shaped by the Great Migrati on, differential sorting in response to pollution, and other factors. Our findings highlight that the equity implications of siting long-lived infrastructure can differ dramatically depending on the time span considered.
