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, 2025 We 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.
The Anatomy of Chinese Innovation: Insights on Patent Quality and Ownership Philipp Boeing, Loren Brandt, Ruochen Dai, Kevin Lim, Bettina Peters, May 07, 2025 Chinese patenting has become narrower and less innovative over time. The role of overseas knowledge has also declined sharply. These findings are salient in the context of a marked slowdown in economic growth in China and rising concerns of technological decoupling with the US.
Debt Management and Strategic Interactions in Top-down Bureaucracy: Evidence from China Xi Qu, Zhiwei Xu, Jinxiang Yu, Apr 30, 2025 The Chinese central government implemented a series of measures to establish a top-to-bottom debt ceiling management system starting in 2015. Under this regulatory framework, public debt issuance for a prefecture city is subject to a ceiling (quota) determined through a hierarchical procedure. Based on a comprehensive dataset, we investigate what factors determine the allocations of debt ceiling to prefectural cities in China after the debt management reform. We find that the distributional outcome of the debt ceilings relies on the bilateral interactions of local and their superior governments. We also estimate the effect of ceiling allocation on the real economy, as well as the potential risk associated with implicit debt accumulation.
Place Prosperity vs People Prosperity: Migration and the Intergenerational Transmission of Knowledge Carol H. Shiue, Wolfgang Keller, Apr 23, 2025 The trajectory of an economy's development can often be better understood through the historical experiences of its populace. Long before the availability of comprehensive official data, Chinese family genealogies are a valuable resource for reconstructing economic evolution over time, as the following shows.
Drive Down the Cost: Learning by Doing and Government Policies in the Global EV Battery Industry Panle Jia Barwick, Hyuk-soo Kwon, Shanjun Li, Nahim Bin Zahur, Apr 16, 2025 Electric vehicle (EV) battery costs have fallen over 90% in the last decade. This study examines how learning-by-doing (LBD) drives this decline and interacts with government policies such as consumer EV subsidies and local content requirements. Leveraging rich data on EV models and battery suppliers from 13 countries with largest EV sales that account for 95% of global EV sales, we develop a structural model of the EV industry that incorporates consumer choices and pricing strategies by EV producers and battery suppliers....
Input-Trade Liberalization, Female Skill Intensity, and Fertility in China Feng Chen, Renliang Liu, Miaojie Yu, Apr 09, 2025 The interplay between trade liberalization and demographic behavior illuminates the challenges of reconciling career and family. This paper examines how gender-specific trade liberalization influences fertility, leveraging a Bartik-style shift-share instrumental variable strategy that incorporates female skill intensity into input tariff exposure. We find that input-trade liberalization significantly reduces fertility, particularly among highly educated women, private sector employees, and first-time mothers—groups experiencing the steepest career-family trade-offs. Mechanism analysis shows that enhanced labor market prospects raise the opportunity cost of childbearing, delaying or reducing family formation. These findings underscore the socioeconomic implications of trade policy for demographic trends.
Beyond the Fundamentals: How Media-Driven Narratives Influence Cross-Border Capital Flows Isha Agarwal, Wentong Chen, Eswar Prasad, Apr 02, 2025 We provide the first empirical evidence on how media-driven narratives influence cross-border institutional investment flows. Applying natural language processing techniques to 1.5 million newspaper articles, we document substantial cross-country variation in sentiment and risk indices constructed from domestic media narratives about China in 15 countries. These narratives significantly affect portfolio flows, even after controlling for macroeconomic and financial fundamentals. This impact is smaller for investors with greater familiarity or private information about China and larger during periods of heightened uncertainty. Political and environmental narratives are as influential as economic narratives. Investors react more sharply to negative narratives than positive ones.
Banking and Banking Reforms in China in a Model of Costly State Verification Jie Luo, Cheng Wang, Mar 26, 2025 We present a macro view of China’s financial system, in which a monopolistic banking sector coexists endogenously with bonds and private loans. In equilibrium smaller firms raise finance from private lending, larger firms do so through bank loans, and the largest firms do so by issuing bonds. The model predicts that expanding credit supply increases bank loans but reduces bond finance and private lending, in absolute terms and relative to total credit. In addition, removing the interest rate ceiling on bank lending—a recent reform in China—induces larger loans and higher lending rates, lowering the share of bank loans in total credit. We present empirical evidence to support these predictions.
High-Speed Rail and China's Electric Vehicle Adoption Miracle Hanming Fang, Ming Li, Long Wang, Yang Yang, Mar 19, 2025 We investigate whether high-speed rail (HSR) connectivity influences electric vehicle (EV) adoption, using a quasi-natural experiment from China’s HSR expansion and several identification strategies. Our findings consistently show that, by alleviating range anxiety, the expansion of HSR can account for up to one third of the increase in EV market share and EV sales in China during our sample period from 2010 to 2023, with effects particularly pronounced in cities served by faster HSR lines. These results suggest that transportation infrastructure can play a complementary role in accelerating the transition to electric mobility.
E vs. G: Environmental Policy and Earnings Management in China Darwin Choi, Feifei Lai, Mar 12, 2025 We examine the conflict between environmental and governance issues arising from China’s automatic air pollutant monitoring system, introduced in 2012. Our findings suggest that polluting firms engage in downward earnings management to potentially minimize regulatory attention, with factors such as firm size, profitability, and market conditions influencing the extent of this behavior. This study highlights the unintended consequences of environmental policies.

How Liberalizing Trade with China Led to a Boom in International Students in the US Gaurav Khanna, Kevin Shih, Ariel Weinberger, Mingzhi Xu, Miaojie Yu, Aug 16, 2023 Focusing on China’s accession to the World Trade Organization, we show that Chinese cities with more exposure to trade liberalization sent more students to US universities.
Regional Variation of GDP per Head within China, 1080–1850: Implications for the Great Divergence Debate Stephen Broadberry, Hanhui Guan, Sep 28, 2022 We provide the first regional breakdown of GDP per head for China from the Song dynasty to the Qing, so that regions of similar size can be compared between Europe and Asia to establish the timing of the Great Divergence of living standards.
Combating Cross-Border Externalities Shiyi Chen, Joshua Graff-Zivin, Huanhuan Wang, Jiaxin Xiong, Sep 21, 2022 China implemented a pioneering policy in 2011, the Ecological Compensation Initiative (ECI), which establishes side payments between upstream and downstream provinces in the Xin’an River Basin.
Assessing and Addressing the Coronavirus-Induced Economic Crisis: Evidence from 1.5 Billion Sales Invoice Zhuo Chen, Pengfei Li, Li Liao, Zhengwei Wang, Aug 31, 2022 We probe the effects of the COVID-19 pandemic and the subsequent containment policies on business activities in China by exploiting big data on 1.5 billion sales invoices. The average drop in sales was between 23% and 35%, depending on firm size, for the 12-week period after the Wuhan lockdown.
Industrial Land Discount in China: A Public Finance Perspective Zhiguo He, Scott Nelson, Yang Su, Anthony Lee Zhang, Fudong Zhang, Jul 25, 2022 Local governments, which serve as monopolistic land sellers in China, face a trade-off when deciding to supply residential land versus industrial land. This trade-off is determined by the different time profiles of revenues from industrial and residential land sales, local governments’ financial constraints, and the extent of local governments’ tax revenue sharing with other levels of government.
Industry/Policy View Omnia Juncta in Uno: Foreign Powers and Trademark Protection in Shanghai’s Concession Era Laura Alfaro, Cathy Ge Bao, Maggie X. Chen, Junjie Hong, Claudia Steinwender, Jul 20, 2022 Trademarks, which identify the source of goods and services, account for the majority of intellectual property filings worldwide. We investigate how firms adapt to the introduction of trademark institutions by exploring a historical precedent: China’s trademark law of 1923, an unanticipated and disapproved response to end foreign privileges in China.
Dollar Funding Stresses in China Laura Kodres, Leslie Sheng Shen, Darrell Duffie, Jul 13, 2022 The need for US dollar funding during the financial stresses of March 2020, as the COVID-19 pandemic shocked markets, was evident in a number of countries (Avdjiev, Eren, and McGuire 2020; Bahaj and Reis 2020).
Serial Entrepreneurship in China Loren Brandt, Ruochen Dai, Gueorgui Kambourov, Kjetil Storesletten, Xiaobo Zhang, Jul 06, 2022 New firms have been an important engine of growth in the Chinese economy (Brandt, Van Biesebroeck, and Zhang 2012). Drawing on data on the universe of all firms in China, we study entrepreneurship and the creation of new firms in China through the lens of entrepreneurs who operate a series of firms over their lifetime, i.e., serial entrepreneurs (SE).
An Empirical Overview of Chinese Capital Market Grace Xing Hu, Jun Pan, Jiang Wang, Jun 29, 2022 We provide an empirical review of the Chinese capital market, focusing on the basic return and risk characteristics of its major asset classes, as well as a comparison to the US market. All major asset classes in China have significant higher volatilities than their counterparts in the US market, but they do not always yield larger returns. Small-company stocks, short-, medium-, and long-term treasury bonds outperform their US counterparts, while large stocks underperform and long-term enterprise bonds yield similar returns.
Mapping U.S.-China Technology Decoupling, Innovation, and Firm Performance Pengfei Han, Wei Jiang, Danqing Mei, Dec 01, 2021 We develop measures for technology decoupling and dependence between the U.S. and China based on combined patent data. The first two decades of the century witnessed a steady increase in technology integration (or less decoupling), but China’s dependence on the U.S. increased (decreased) during the first (second) decade. Decoupling in a technology field predicts China’s growing dependence on U.S. technology, which, in turn, predicts less decoupling further down the road...
