Exporting and Pollution Abatement Expenditure: Evidence from Firm-Level Data
The relevance of analyzing whether exporting firms engage in greater pollution abatement cannot be overemphasized. For instance, the question relates to the possibility of export promotion policies being environmentally beneficial. In fact, the issue is especially relevant for developing countries typically characterized by ineffective environmental regulation. However, despite the significance of the topic, the extant literature examining the environmental consequences of firm-level trade is skewed toward developed countries. Moreover, the existing contributions rarely attend to concerns ...

Pollution Taxes and Clean Subsidies in an Open Economy
In open economies, the effectiveness of carbon taxes is diminished by “pollution leakage,” where some polluting activity shifts abroad because of the tax. This paper shows that the same conditions that lead to pollution leakage enhance the efficacy of clean subsidies. As a result, the optimal policy in an open economy combines a pollution tax and a clean subsidy, the balance of which depends on the leakage rate. Furthermore, efficient policy sets the sum of the tax and subsidy rates, a measure of policy ambition, equal to the marginal damages from pollution, and does not depend on the ...

President's perspective
Mexico's long-awaited energy reform should, if carefaully and deliberately implemented, increase oil and gas production and reverse a nine-year trend of declining output.

Firms’ Supply Chain Adaptation to Carbon Taxes
This paper studies how firms adjust input sourcing in response to climate policy. Using the EU Emissions Trading System (ETS) as a natural experiment and French product-level import and production data, we show that firms increasingly shifted imports of ETS-regulated inputs to non-EU countries over the 2010s as the policy became more stringent, indicating carbon leakage. This leakage is economically significant: the share of ETS-regulated products sourced from outside the EU rose by 4.3 percentage points after the ETS was implemented. Motivated by these empirical findings, we estimate a ...

What Can Undermine a Carbon Tax?
Several countries have implemented a carbon tax or cap-and-trade system to establish high carbon prices and create a disincentive for the use of fossil fuels. Essentially, the tax encourages firms to substitute toward low carbon emission energy. Costs also rise for firms down the supply chain that use production inputs with high-emission content, so the total impact of a carbon tax can be large. In practice, however, firms also have an incentive to find an offset to a carbon tax. In this post, based on our recent work, we present evidence of one such adaptation strategy. We show that French ...

What Is a Carbon Tariff and Why Is the EU Imposing One?
The European Union has been an early adopter of carbon policies, with the introduction of the EU Emissions Trading System (ETS) in 2005. This scheme sets a common price for carbon and is applied to the most polluting manufacturing sectors. By increasing the cost of emissions-intensive production, the system incentivizes firms to decrease their use of fossil fuels. However, as we show in a companion post, the policy’s impact was moderated by firms increasing their reliance on high-emissions imports. To eliminate this workaround, the EU will expand the ETS to imports in 2026, through the ...
