Abstract：
Attribute-based subsidies are commonly used to promote the diffusion of energy-efficient products. These products are often manufactured in industries characterized by oligopolies with significant market power. We first develop a theoretical framework of attribute-based subsidies in the presence of market power. The model illustrates that the welfare impact of subsidies critically hinges on how firms choose product attributes and the resulting implications on environmental externalities and market power. We then develop and estimate an equilibrium model with endogenous product attributes using comprehensive data on China's vehicle market. Based on model estimates, we conduct counterfactual simulations to examine the impacts of different subsidy designs. Relative to attribute-based subsidies, uniform subsidies favor small and environmental-friendly vehicles but exacerbate the quantity distortion from market power for high-quality products. The environmental gain from a uniform subsidy is modest relative to the consumer welfare loss. In contrast, subsidies based on driving range, battery capacity or vehicle weight generate a large consumer surplus by improving product quality and mitigating market power. The capacity-based subsides induce production attributes that are valued by consumers, mitigate market power, and lead to the largest welfare gain at a moderate cost of environmental externalities. Our paper highlights the importance of incorporating attribute choice and market power considerations in designing environmental policies.

Intro to The Digital Star Seminar Series：
The Digital Star Seminar Series is co-hosted by the China Digital Economy Research Center of School of Economics, Zhejiang University, and the Zhejiang University-The Chinese University of Hong Kong Digital Economy Joint Research Center. This series of seminars will study the development of the digital economy and China's economic transformation based on the practice of China's digital transformation. We will invite domestic and overseas scholars to share and discuss the latest research on the digital economy and the Chinese economy. We hope that this academic platform can become a paradise for the study of the digital economy. More importantly, it can generate insights that significantly impact the digital economy and Chinese economy, which will help promote digital transformation and high-quality economic development in Chinese society.
