Growth accounting identified off an official BEA deflator revision: reattributing 2.8 log points of US electricity productivity growth to capital deepening turns measured stagnation into decline.

Sun–Abraham event studies across 49 countries and 794 reforms: feed-in tariffs accelerate deployment; carbon pricing does not.

Event-study DiD with an instrument from 77% IPCC author turnover: citation raises annual visibility 67%, reallocating rather than expanding attention.

Mapping of 24,449 IPCC references matched to 476,783 secondary citations: assessment visibility tracks topical fit, not journal prestige.

Aggregates sectoral transition scenarios into economy-wide productivity, backtested on EU KLEMS: neutral for the UK, +6pp globally by 2050.

Growth accounting that identifies the direction of technical change without estimating an elasticity of substitution: on EU–US KLEMS data, fossil-saving innovation saves skilled, not unskilled, labour.

Microsimulation using French household budget surveys: lump-sum recycling halves the emissions reduction, while targeted recycling to low-income households preserves the emissions reduction.

The distributional consequences of environmental policies are a major issue for the public acceptability of energy transitions, as the Yellow-vest demonstrations highlighted. Our objective is to assess the short and mid-term distributional impacts of policy packages on firms and households – rather than of single policy instruments - including carbon taxing, technology adoption subsidies and compensating lump-sum transfers.

This paper is a micro-simulation of the adoption of compressed natural gas in heavy-duty vehicles based on real French data on industrial flows in 2018 from the automotive manufacturer Renault. We show that bio-sourced natural gas can be cost-effective for heavy-duty trucks and that detours to reach refuelling stations are key parameters for emissions. That is why fossil natural gas trucks emit more than diesel trucks in real conditions due to low-density of refuelling network.
