This research examines the impact of data centre expansion on US electricity prices. Findings indicate that entry between 2010 and 2024 increased average retail rates by 2.7%. These costs are concentrated among investor-owned utilities and pronounced in deregulated markets or regions with limited spare capacity.

This research examines the governance of dual-class firms, documenting a significant rise in their prevalence among US initial public offerings between 2000 and 2025. It identifies that these structures are increasingly concentrated in founder-led, venture-backed technology companies, while empirical evidence suggests they do not necessarily lead to CEO entrenchment.

Occupational Safety and Health Administration inspections significantly reduce injuries at nearby, uninspected workplaces. An inspection reduces injuries at same-ZIP-code establishments by 11 per cent, preventing six times more injuries through spillovers than direct effects. These findings suggest conventional evaluations substantially understate the social returns to regulatory enforcement.

This NBER working paper examines the impact of air pollution on 10 million US high school students. It finds that moderate pollution levels reduce annual learning by 19 per cent. Disadvantaged students experience three times more harm, significantly widening racial and socio-economic achievement gaps.

This research examines GSE fee waivers for lower-income first-time homebuyers, revealing that lenders pass through less than 40% of these savings. Intermediaries captured over 60% of the $1.5 billion benefit. High-cost loan officers and non-banks show the lowest pass-through, highlighting significant market power and search frictions.

A longitudinal database tracking voluntary climate commitments and greenhouse gas targets for U.S. public companies in the Russell 3000 index from 2000 to 2024.

This research explores the emergence of partisan corporate governance, focusing on Texas as a conservative competitor to Delaware. It examines legislative changes to limit shareholder litigation and influence, the regulation of proxy advisors, and the resulting legal and political risks for corporations navigating an increasingly politicised regulatory environment.

This research examines "reverse capture", where government actors pressure large asset managers to advance political agendas. It analyses how expanding presidential power and market concentration enable this dynamic, using the ESG retreat as an illustration. The authors recommend narrowing fiduciary duties to insulate investment stewardship from political interference.

This report investigates the influence of fossil fuel companies and trade associations on US carbon market regulations. It details extensive lobbying in California and representative roles at the federal level, arguing that these efforts maintain low-quality credits to delay genuine decarbonisation and enable greenwashing.

The Global Climate Policy Project is a collaborative research initiative between Harvard University and the Massachusetts Institute of Technology that focuses on international climate policy and energy economics.

A framework and diagnostic tool developed by the American Society of Adaptation Professionals to help climate projects move from planning to investment-ready status. It provides criteria for assessing project maturity, equity, and financial feasibility.

This research examines the environmental and social impacts of rapid data centre expansion in the United States. It highlights how generative AI infrastructure disproportionately burdens marginalised communities through pollution, increased utility costs, and resource depletion. The authors call for a "more human pace" centred on environmental justice.

The Clean Investment Monitor: US Update is a benchmark series providing a comprehensive database of clean energy and transportation investment across the United States. Produced by Rhodium Group and MIT-CEEPR, it tracks the manufacture and deployment of greenhouse gas emission-reducing technologies across manufacturing, energy and industry, and retail segments.

This research examines shareholder pressure on US fossil fuel firms’ climate strategies. Using NLP to analyse 10-K filings and SEC regulatory changes, it finds limited impact on substantive reforms. Firms often employ symbolic disclosures or procedural tactics to resist decarbonisation, suggesting that mandatory policy is required for transition.

A dataset and analysis by Climate Central tracking fire weather trends across the U.S. from 1973 to 2025. It helps users understand the increasing frequency of high heat and low humidity conditions that drive wildfire risk.

This research examines AI diffusion through US firms, distinguishing between organisational adoption and worker-level use. While adoption is growing, it remains concentrated in large, knowledge-intensive sectors. Findings indicate AI primarily augments worker tasks, with capital substitution being more prevalent than labour displacement at this stage of technological integration.
