The Effect of Carbon Taxes on Aggregate Productivity

Investment Rating - The report does not explicitly provide an investment rating for the industry analyzed. Core Insights - The implementation of a carbon tax in the Dominican Republic is expected to impact aggregate total factor productivity (TFP) through resource allocation, with varying effects depending on existing market distortions among firms [4][9][10]. - A carbon tax is more effective when applied to fuels rather than electricity, leading to productivity gains for most sectors by reallocating resources from low-productivity to high-productivity firms [4][15]. - The study emphasizes the importance of considering existing input market distortions when evaluating the impact of environmental taxes [4][10]. Summary by Sections Introduction - The Dominican Republic aims to reduce greenhouse gas emissions by 27% by 2030, and the introduction of a carbon tax is considered a potential regulatory intervention to incentivize firms to reduce fossil fuel consumption [8][9]. Theoretical Framework - The report develops a model to analyze how a carbon tax affects firms' energy input consumption and overall productivity, highlighting the heterogeneous impact based on firms' existing market distortions [12][24]. Empirical Analysis - Utilizing detailed firm-level data from 2009 to 2018, the analysis indicates that a carbon tax could generate approximately $920 million in revenue if set at$110 per ton of CO2, representing about 10% of total taxes collected in 2018 [13][32]. - The sectors most affected by the carbon tax are identified as transport, cement, and hospitality, which have significant carbon emissions footprints [13][37]. Results and Discussion - The findings suggest that the introduction of a carbon tax could shift the burden of market distortions from high productivity firms to low productivity ones, potentially increasing aggregate TFP for most sectors [4][15]. - The report concludes that the effectiveness of a carbon tax is contingent upon the existing distortions in energy consumption and the productivity levels of firms within the Dominican Republic [4][10].
