This study examines how localized carbon reduction policies affect corporate green productivity. Leveraging a quasi-experiment from China’s low-carbon pilot rollout across cities, we find that these interventions significantly increased polluting firms’ green productivity. The gains persisted over time and were greater for firms with higher financial constraints, lower market competition, and lower capital intensity. Textual analysis reveals enhanced executive environmental cognition as a plausible channel. Overall, the results provide robust evidence that well-designed local regulations can achieve a win-win outcome of lower emissions and higher efficiency.

We present a novel methodology for constructing portfolios to hedge economic and financial risks arising from climate change. We utilize ChatGPT-4 to identify climate-related conversations during earnings conference calls and connect these time-stamped transcripts with high-frequency stock price data pinpointed to the conversation level. This approach allows us to assess a company’s dynamic exposure to climate change risks by analyzing real-time stock price responses to discussions about climate issues between managers and analysts. Our proposed portfolio, constructed by taking long (short) positions in stocks with positive (negative) market responses to climate conversations, appreciates in value during future periods with negative aggregate climate news shocks. Compared to portfolios constructed using alternative methods, our real-time market response-based portfolios demonstrate superior out-of-sample hedge performance. A key advantage of our approach is its ability to capture time-series and cross-sectional variations in stocks’ rapidly-evolving exposures to climate risk, relying on the timing of when climate-related issues become salient topics that warrant conference call discussions and real-time market responses to such conversations. Additionally, we showcase the versatility of our approach in hedging other types of dynamic risks: namely political risk and pandemic risk.

This study investigates the relationship between investors’ prior gains or losses and their adoption of extrapolative beliefs. Our findings indicate that investors facing prior losses tend to rely on optimistic extrapolative beliefs, whereas those experiencing prior gains adopt pessimistic extrapolative beliefs. These results support the theory of motivated beliefs. The interaction between the capital gain overhang and extrapolative beliefs results in noteworthy mispricing, yielding monthly returns of approximately 1%. Motivated extrapolative beliefs comove with investors’ survey expectations and trading behavior, and help explain momentum anomalies. Additionally, households are susceptible to this belief distortion. Institutional investors can avoid overpriced stocks associated with motivated (over-)optimistic extrapolative beliefs.

This paper examines the impact of collateral shocks on corporate financialization using a sample of Chinese-listed firms from 2008 to 2021. We find a statistically and economically significant positive effect of collateral appreciation on financialization, consistent with profit-chasing motives, even after addressing endogeneity concerns. Additional tests reveal the effects are more pronounced among financially constrained, bank-dependent, and high-agency-cost firms. Financialization also elevates the risktaking and financial risks of firms. Overall, we provide novel evidence that collateral shocks stimulate corporate financialization, with implications for incentives, regulation, and systemic risk monitoring.

Based on the expected utility under uncertain probability distribution, we explore whether the ambiguity of individual stocks is priced in China’s A-share market and the mechanism behind the ambiguity premium phenomenon. Theoretically, when the asset price is in a specific price range, investors with ambiguity aversion do not participate in the transaction of the asset. As the ambiguity of assets increases, investors with high ambiguity aversion withdraw from the market, and investors with low ambiguity aversion remain in the market (the limited market participation phenomenon); investors who remain in the market due to lower ambiguity aversion are also willing to accept a low ambiguity premium. Empirically, we use "the volatility of the distributions of daily stock returns within a month" to measure monthly ambiguity; and find that (1) the equal-weighted average returns of the most ambiguous portfolios (top 20%) are significantly lower 1.38% than those of the least ambiguous portfolios (bottom 20%); (2) ambiguity still significantly negatively affects the cross-sectional stock return after controlling for common firm characteristics; (3) the higher the ambiguity, the lower the future trading activity, the empirical results are consistent to the theoretical predictions. Those findings reveal the mechanism of the negative ambiguity premium in the A-share market, provide new ideas for further building a factor pricing model suitable for the A-share market, and provide a fresh perspective for preventing systemic financial risk.

This paper employs a difference-in-differences approach to study whether a Chinese audit firm improves its competencies through organizational learning after one of its audit teams has a client cross-listed in the US. Among a group of companies that are only listed in China, we define those audited by Chinese audit firms that are not international Big 4 affiliates and have cross-listed clients as the treatment group, and companies audited by other audit firms as the control group. We find an improvement in audit quality for the treatment group after their audit firms have cross-listed client experience in the US, and this improvement is not attributable to the effect of joining an international accounting firm network, registration with the PCAOB, or the consolidation in the audit market. A survey of auditors corroborates these findings and provides evidence on audit firms’ specific actions to facilitate learning. Our findings shed light on the benefits of auditing cross-listed clients in the US and its positive externality on improving the audit quality of non-US-listed companies in China.

We develop novel high-frequency indices that measure climate attention, covering a wide range of both developed and emerging economies. This is achieved by analyzing the text of over 23 million tweets published by leading national newspapers on Twitter during the period from 2014 to 2022. Our findings reveal that a country experiencing more severe climate news shocks tends to see both an inflow of capital and an appreciation of its currency. In addition, brown stocks in highly exposed countries experience large and persistent negative returns after a global climate news shock. These outcomes align with the predictions of a risk-sharing model in which investors price climate news shocks and trade consumption and investment goods in global markets

Using a comprehensive factor zoo, we document a notable factor MAX premium in the Chinese market. Factors with high maximum daily returns consistently outperform those with low maximum returns by 0.82% per month in the future, on a risk-adjusted basis. This premium remains robust controlling for various factor characteristics, and is not sensitive to the selection of factors. The factor MAX anomaly stands apart from lottery-type stock anomalies and contributes to elucidate most of these anomalies. The factor MAX premium concentrates in high-eigenvalue principal component factors, shedding light on the prevalent lottery preferences for factor investing in China’s A-share market. We document pronounced existence of factor MAX anomaly in the United States and other G7 countries.

This paper focuses on how Chinese and global economic policy uncertainties (CNEPU and GEPU) and geopolitical risks (CNGPR and GGPR) affect the growth of inbound tourism in China using ARDL and NARDL models as well as monthly series of Chinese inbound tourism revenue and arrivals. Firstly, we find significant effects of CNGPR and GGPR as well as GEPU on the growth of inbound tourism in Hainan Province and even in China nationwide, while the impact of CNEPU is limited. Among them, GEPU always has a significant long-term negative impact on inbound tourism growth (both inbound tourism revenue and inbound tourism arrivals). However, CNGPR has a significant short-term negative impact on inbound tourism growth in China nationwide but it has a significant long-term negative impact on inbound tourism growth in Hainan Province. Besides, estimation results of NARDL model further show the significant short-term effects of GEPU and GGPR on the growth of inbound tourism arrivals in Hainan Province and even in China nationwide, and such short-term effects are always significantly asymmetric. Among them, the negative components of GGPR can always more influence the growth of inbound tourism arrivals. However, the positive components of GEPU can more influence the growth inbound tourism arrivals in Hainan Province, but the negative components of GEPU can more influence the growth of inbound tourism arrivals in China nationwide.

本文探究了财政赤字货币化政策在中短期内提振总需求、促进经济增长的有效性，而银行体系的准备金规模状态是影响财政赤字货币化政策效果的关键因素。本文将财政赤字货币化政策定义为融资方式依赖于货币政策工具协调配合的扩张性财政政策，将准备金规模状态划分为稀缺准备金和充足准备金状态，并依据超额准备金数量相对流动性需求的充足程度对准备金规模状态进行了严格定义。依托包含银行体系和财政货币政策互动机制的动态随机一般均衡模型，本文解析和定量地研究了不同准备金规模状态下各类财政赤字货币化政策的效果，并以理论模型蕴含的检验标准为依据，分析和预测了我国当前准备金规模状态及未来变化趋势。研究结果表明，稀缺准备金状态下依赖准备金数量工具和充足准备金状态下依赖超额准备金利率工具配合的财政赤字货币化政策能够提升扩张性财政政策的有效性。我国银行体系当前处于稀缺准备金状态，但正在逐步向充足准备金状态靠近。现阶段政策当局可以考虑通过中央银行购买国债实施财政赤字货币化政策。
