Energy, Emissions and the Product Mix: Understanding the Role of Product Portfolio Choices in the Green Transformation 1: ZEW Mannheim, Germany; 2: University of Mannheim, Germany Understanding what leads firms to reduce their greenhouse gas emissions is crucial to manage the green industrial transformation. Aggregate evidence suggests that a shift towards cleaner product portfolios is an important channel through which firms decrease their emissions. But using German administrative micro-data, we show that firm-level product portfolio choices do not follow predictions of existing theory: We observe a re-shuffling within the most emissions-intensive products rather than a shift away from them. We also find that firms with wider product scopes are more emissions-intensive than others – even though they should be the most productive firms according to existing theory. To make sense of these findings, we extend the canonical model of product portfolio choice to include energy as a factor of production. In our model framework, heterogeneous energy prices between firms (e.g. due to differences in regulation or fuel composition) can explain the unexpected empirical patterns we observe. This has important implications for the design of green industrial policy. | |
