Abstract

We analyze how a potential CO₂eq-tax on the most emission-intensive agricultural goods in Germany affects CO₂eq-emissions and the income distribution.Based on data from the German survey of income and expenditure, we use a linear approximated Exact Affine Stone Index demand system to estimate own-price and cross-price elasticities for meat, dairy goods and eggs. These elasticities allow us to obtain demand changes and thus emission reductions following the introduction of a CO₂eq-weighted carbon tax based on the social cost of carbon. We find that it can reduce annual agricultural emissions in Germany by more than 15.3 MtCO₂eq or about 22.5%. The tax generates an annual revenue of more than 8.2 billion EUR. Since the carbon tax is regressive, we consider the distributional effects of a per capita lump-sum compensation scheme. We show that this “fee and dividend” approach has a slightly progressive effect on the distribution of income.

对农产品征收二氧化碳排放税的排放和分配效应——以德国为例

我们分析了德国对排放最密集的农产品征收二氧化碳排放税的可能性如何影响二氧化碳排放和收入分配。基于德国收入和支出调查的数据，我们使用线性近似的精确仿射石指数需求系统来估计肉类、乳制品和蛋类的自身价格和交叉价格弹性。这些弹性使我们能够获得需求变化，从而在引入基于碳的社会成本的二氧化碳当量加权碳税后减少排放量。我们发现，它可以减少德国每年1530多万吨二氧化碳当量的农业排放量，约为22.5%。这项税收每年产生超过82亿欧元的收入。由于碳税是递减的，我们考虑了人均一次性补偿方案的分配效应。我们表明，这种“费用和股息”的方法对收入分配有轻微的渐进影响。

期刊介绍： Food Policy is a multidisciplinary journal publishing original research and novel evidence on issues in the formulation, implementation, and evaluation of policies for the food sector in developing, transition, and advanced economies. Our main focus is on the economic and social aspect of food policy, and we prioritize empirical studies informing international food policy debates. Provided that articles make a clear and explicit contribution to food policy debates of international interest, we consider papers from any of the social sciences. Papers from other disciplines (e.g., law) will be considered only if they provide a key policy contribution, and are written in a style which is accessible to a social science readership.
