Policy strategies to tackle rebound effects: A comparative analysis

Jaume Freire-Gonzalez et al.

Summary: Promoting energy efficiency is an effective strategy to reduce energy use, but rebound effects can undermine its effectiveness. By implementing a complex policy strategy, we can offset rebound effects and improve GDP at a low cost.

Is a fair energy transition possible? Evidence from the French low-carbon strategy

Emilien Ravigne et al.

Summary: The study aims to evaluate the short and mid-term distributional impacts of policy packages, including carbon taxing, technology adoption subsidies and compensating lump-sum transfers. By combining micro-simulation and macroeconomic modelling techniques, the study explicitly considers the heterogeneity of households' behavior and the distribution of energy-efficient durable technologies among consumers. The findings suggest that focusing technology adoptions on the largest energy consumers can reduce the discrepancy of impacts between rural and urban households, but it may worsen the regressivity of carbon taxation if households are not rebated their carbon tax payments. In the short term, recycling schemes favoring poorer households can offset the regressivity of carbon taxation.

Does a Carbon Tax Reduce CO2 Emissions? Evidence from British Columbia

Felix Pretis

Summary: By using various methods including difference-in-differences and synthetic control, the study shows that the introduction of North America's first major carbon tax has reduced transportation emissions but hasn't led to significant reductions in overall CO2 emissions. The study proposes a new method to evaluate policy effectiveness and finds that carbon pricing and trading schemes in other provinces are not detected as significant interventions. Instead, closures and efficiency improvements in untaxed provinces have resulted in reduced emissions. Overall, the study suggests that existing carbon taxes may be too low to have a significant impact.

Heterogeneous structural breaks in panel data models

Ryo Okui et al.

Summary: This paper introduces a new model and estimation procedure for panel data to identify heterogeneous structural breaks. By developing a hybrid estimation procedure that combines fixed effects approach and adaptive group fused Lasso, it can consistently identify latent group structure and demonstrate good performance in finite samples.

Difference-in-differences with variation in treatment timing

Andrew Goodman-Bacon

Summary: The paper explores the relationship between the two-way fixed effects estimator and all possible two-group/two-period DD estimators, showing that it is a weighted average. A causal interpretation of two-way fixed effects DD estimates requires meeting the parallel trends assumption and constant treatment effects over time.
