Abstract In the presence of intersectoral linkages, sector-specific carbon tax changes can have complex general equilibrium effects. In particular, a carbon tax on the emissions of a sector can lead to an increase in aggregate emissions. We analytically characterise how incremental taxes on the emissions of any set of sectors affect aggregate emissions. We show that carbon tax reforms that target sectors based on their position in the production network can achieve a greater reduction in aggregate emissions than reforms that target sectors based on their direct emissions alone. We illustrate the effects of carbon tax reforms by calibrating our intersectoral network model to the economies of two countries.

Publisher Copyright: © 2022 The Authors We use station-level price data and a significant diesel fuel carbon tax reform to study who bears the economic burden of fuel carbon taxes. We use a difference-in-differences strategy to estimate the pass-through of the large carbon tax increase to retail prices, where we compare retail diesel prices faced by private motorists to retail gasoline prices. We find that on average fuel carbon taxes are less than fully passed through to consumer prices, which suggests that consumers and the supply chain split the burden of these taxes. Using information on station location, we match price observations with postcode-level average incomes and measures of urbanization, and show that there are significant differences in the pass-through rate across areal incomes and between rural and urban areas up to one year after the reform. The effect of fuel carbon taxes on consumer prices decreases with areal income and with the degree of urbanization. Peer reviewed

This article examines the role of environmental taxation in mitigating environmental problems and contributing to sustainability in Mexico. It focuses on environmental tax revenues and tax expenditures since the 2014 Public Financial Reform (PFR), according to pro- or anti-environmental orientation. The research carried out combines the study of the regulation of the selected tax instruments, their classification and the empirical analysis of the tax revenues and tax expenditures associated with the different taxes over the periods of validity of the taxes and benefits studied, using the databases of the CIAT and the Mexican SHCP. A critical analysis addresses the weak environmental function of environment-related taxes (IEPS, ISAN…), as well as the late implementation and reduced impact of the carbon and pesticide taxes introduced in 2014. The evolution of tax incentives and expenditure is thoroughly examined by examining both environmental measures, which have evolved positively but within a very reduced level, and the most prevalent tax expenditure measures, with harmful impacts to the environment. Based on the results obtained, long-term structural changes in the Mexican tax system are suggested. As for the short to medium term, profound changes in tax expenditure are proposed to eliminate of those tax benefits harmful to the environment, introduce of tax benefits for circular activities (e.g., repairing, reusing and remanufacturing) and broaden the carbon tax base and rates. The conclusions include recommendations for moving towards a systemic green tax reform that assists the transformation towards a sustainable economy.

RésuméNous introduisons le concept d'empreinte carbone dans un modèle d'offre globale et demande globale avec formation imparfaitement concurrentielle des prix et salaires et en examinons les propriétés de l'équilibre en présence d'une politique climatique. Nous étudions deux instruments possibles de cette politique, une taxe carbone ou un quota de permis de pollution. Nous montrons qu'à court terme, la politique climatique (ou son durcissement) constitue à la fois un choc d'offre globale négatif et, ceteris paribus, un choc de demande globale positif. Elle provoque donc des effets inflationnistes mais a un impact ambigu sur l'activité économique, l'emploi et le chômage. Ce n'est que dans une économie avec des ridigités nominales suffisantes que la politique climatique stimulera -sous certaines conditions- l'activité à court terme. Dans tous les cas de figure, elle pèsera négativement sur les salaires réels.Nous étudions encore les interactions entre la politique climatique et les politiques macroéconomiques traditionnelles de demande (stimulus budgétaire ou monétaire) et d'offre (baisse des cotisations sociales). Les effets multiplicateurs de ces politiques sont influencés par l'existence d'une politique climatique et diffèrent selon l'intrument choisi (taxe ou permis).Nous montrons les conditions sous lesquelles une réforme combinant durcissement de la politique climatique et baisse des cotisations sociales sur le travail peut atteindre le double objectif de réduire l'empreinte carbone de l'économie et le chômage, sans pénaliser les salaires réels des travailleurs. Une telle politique a toutefois des effets incertains sur le solde des finances publiques.

We demonstrate that the carbon tax imposed by the Canadian province of British Columbia caused a decline in short-run gasoline demand that is significantly greater than would be expected from an equivalent increase in the market price of gasoline. That the carbon tax is more salient, or yields a larger change in demand than equivalent market price movements, is robust to a range of specifications. Along with calculating the reduction in carbon dioxide emissions attributable to the tax, we discuss potential explanations for the differential consumer responses to the carbon tax relative to the market-determined price.

AbstractSupply of a nonrenewable resource adjusts through two margins: the rate at which new fields are opened and the rate of depletion of open fields. The paper combines these margins in a model in which there is a continuum of fields with varying capital costs. Opening a new field involves sinking a capital cost, and the date of opening is chosen to maximize the present value of the field. Depletion of each open field follows a Hotelling rule, modified by the fact that faster depletion reduces the amount that can ultimately be extracted. The paper studies the equilibrium paths of output and price. Under specific but reasonable assumptions on demand and the cost distribution of deposits it is found that the rate of growth of price is constant and independent of the rate of interest, depending instead on characteristics of demand and geology.
