Bilateral Economies of Scope in International Trade
Yao Amber Li, Sichuang Xu, Stephen R. Yeaple, Tengyu Zhao, Jan 15, 2025This paper presents evidence that firms’ export and import decisions within the same foreign market are complementary, due to bilateral economies of scope that allow substantial cost savings when engaging in both activities. By quantifying these savings through a structural model, we show that bilateral economies of scope significantly enhance firms’ participation in international trade and amplify the effects of trade liberalization, offering new insights for policymakers and researchers.
Input Trade Liberalization and Firm Labor Market Power in China
Illenin O. Kondo, Yao Amber Li, Wei Qian, Jul 30, 2025More trade, more jobs? Or fewer? China’s accession to the WTO has catalyzed a rich research agenda on the labor market consequences of trade liberalization. Departing from the assumptions of perfectly competitive labor markets, we ask whether Chinese firms exercised more or less labor market power when input tariffs fell with China’s WTO accession? We show that input trade liberalization reduced labor monopsony power in China, especially for skill-intensive firms and in markets with more labor supply growth.

AI Patents in the United States and China: Measurement, Organization, and Knowledge Flows
Hanming Fang, Xian Gu, Hanyin Yan, Wu Zhu, Jun 16, 2026ebates about artificial intelligence (AI) often ask whether the United States and China are technologically decoupling. Using a new high-precision measure of AI patents, we show a more nuanced picture. AI innovation in the two countries is converging in scale and technological direction, but remains highly asymmetric in institutional organization, geographic diffusion, and cross-border knowledge dependence. Chinese AI patents rely heavily on US frontier technologies, while US reliance on Chinese innovation is more limited.
