A New Method for Estimating Product-Level Emission Intensities and Implications for EU’s Carbon Border Adjustment Mechanism
Ohyun Kwon, Hao Zhao, Min Qiang Zhao, May 14, 2025We develop a new method for estimating product-level emission intensities (PLEI) by combining firm-level emissions with firm-product output data. This methodological innovation produces highly granular emission measures that are essential for both academic research and climate policy design. Applying the method to Chinese manufacturing data, we uncover stark heterogeneity: the top 10% of emission-intensive products account for 75% of emissions but only 4% of exports. We incorporate our PLEI estimates into a general equilibrium trade model to assess the EU’s Carbon Border Adjustment Mechanism (CBAM). Our simulations demonstrate that, at the same carbon price, product-level CBAM achieves substantially greater emissions reductions than sector-level CBAM, while causing markedly less trade disruption. These results underscore the importance of product-level emission intensity data in designing targeted and cost-effective climate policies.
Visible Hands: Professional Asset Managers’ Expectations and the Stock Market in China
John Ammer, John Rogers, Gang Wang, Yang Yu, Jun 11, 2025Mutual funds have become an important type of private institutional investor in Chinese security markets, with assets under management exceeding $3 trillion. We study how Chinese fund managers’ growth expectations affect their equity investment decisions, and in turn, the effects on stock prices. We identify a strong short-run causal effect of growth expectations on stock returns. We also find that fund investment helps bring prices in line with firms’ longer-run earnings prospects.
Does Farming Culture Shape Household Financial Decisions?
Fang Yu, May 01, 2024This article discussing the collectivist culture from traditional rice farming in China leads households to prefer stock market investments and lottery purchases while reducing their need for insurance. This demonstrates the strong influence of cultural heritage on modern financial decisions and highlights the need to consider cultural factors in financial policy making.The collectivist culture from traditional rice farming in China leads households to prefer stock market investments and lottery purchases while reducing their need for insurance.

High-Speed Rail and Local Agricultural Development
Xiaoguang Chen, Binlei Gong, Zhilong Qin, Xiaoli Wang, Jan 07, 2026We study China’s extensive high-speed rail (HSR) expansions to address a key policy concern that large-scale transport infrastructure may undermine agriculture and food security. We find that HSR expansion facilitates the outflow of labor and land from agriculture, yet does not reduce agricultural output because productivity rises.
