  • 详情 Emotions and Fund Flows: Evidence from Managers' Live Streams
    Do investors respond to what fund managers say, or how they look saying it? Using 2,000 live-streamed sessions by Chinese ETF managers and multimodal machine learning, we show that managers’ facial expressions, not their words, drive fund flows. A one-standard-deviation increase in positive facial affect raises next-day flows by 0.17pp (260% of mean). Vocal tone shows weak effects; textual sentiment shows none. Critically, facial expressions predict flows but not returns, indicating pure persuasion rather than information transmission. Effects strengthen when investors are emotionally vulnerable (down markets, retail-heavy funds) and persist 2-3 weeks before dissipating. Our findings challenge the emphasis on textual disclosure in finance and raise questions about investor protection as video communication proliferates.
  • 详情 The Hidden Cost of a Government Contract in China: How VAT Cuts Squeeze Local Fiscal Capacity and Erode Firm Value
    This paper investigates how government fiscal constraints transmit to the private sector through procurement. We exploit three rounds of VAT rate cuts in China (2017–2019) as exogenous shocks to local government revenues. Combining city-level fiscal pressure measures with 9,189 procurement contracts from A-share listed firms, we construct a firm-year exposure index weighted by procurement volumes across cities. We find that exposure to fiscally stressed government buyers significantly depresses firm valuation: a one-standard-deviation increase reduces Tobin's Q and price-to-sales ratios by 5.3% and 4.3%, respectively. This effect concentrates among private firms, those lacking industrial policy support, and firms with lower rent-seeking expenditures—precisely those with weaker bargaining power against government counterparties. Beyond valuation, such exposure leads to a subsequent deterioration in firm fundamentals, characterized by tightened liquidity constraints, reduced investment and financing, and worse information disclosure over a three-year horizon. Land finance partially buffers these effects. Our findings highlight an unintended micro-level consequence of macro fiscal policy: expansionary tax cuts designed to stimulate the private sector may inadvertently harm firms by weakening the government's capacity to fulfill procurement payments.
  • 详情 Financial Information Sources, Trust, and the Ostrich Effect: Evidence from Chinese Stock Investors during a Market Crisis
    Periods of market crisis are often accompanied by heightened fear and information overload, which can induce information avoidance behaviors such as the ostrich effect. While prior research has documented investors’ tendency to avoid unfavorable information, little is known about how different information sources—and trust in those sources—jointly shape such behavior under extreme uncertainty. Drawing on Granular Interaction Thinking Theory (GITT) and employing Bayesian Mindsponge Framework (BMF) analytics, this study examines how investors’ regular securities-related information sources is associated with the ostrich effect during the 2022 market downturn in China, and how these associations are conditioned by trust. Using survey data from 1,451 Chinese individual stock investors, we model investors’ recalled frequency of temporarily disengaging from stock investing as an indicator of information avoidance. The results show that regularly consulting professional sources, financial newspapers, and online forums is associated with information avoidance, whereas reliance on personal relationships and company disclosures is not. Importantly, trust moderates these relationships in distinct ways. Higher trust in professional sources is associated with reduced information avoidance, while higher trust in financial newspapers and online forums amplifies avoidance behavior. Among all sources, the interaction between trust and information referral is strongest for financial newspapers. These findings suggest that trust does not uniformly mitigate fear-driven avoidance. Instead, when combined with high-entropy information sources, trust can exacerbate cognitive and emotional strain, increasing investors’ propensity to disengage. By highlighting the joint roles of informational entropy and trust, this study advances behavioral finance research and offers practical insights for investors, policymakers, and regulators seeking to improve decision-making resilience during periods of market crisis.
  • 详情 Does Auction Design Facilitate Collusion?
    This paper examines how auction design can unintentionally facilitate bidder collusion in land market. Departing from the dominant view that attributes low land concession revenues to corruption, we highlight how features of auction structure enable bidder-side collusion, suppressing sale prices. Using a dataset of land auctions from 15 Chinese cities (2006–2016), we find that two-stage (listing) auctions are significantly more susceptible to collusion than one-stage formats. Empirical evidence shows that sales concluding at the (secret) reserve price occur disproportionately in two-stage auctions, even after controlling for land and market characteristics. We argue that the transparency and sequencing of two-stage auctions, while designed to enhance fairness, inadvertently reduce monitoring costs and facilitate tacit bidder coordination. Our findings underscore the need to jointly consider auction format and reserve price policy in designing land sales to enhance market efficiency and mitigate collusion risks.
  • 详情 Technological Momentum in China: Large Language Model Meets Simple Classifications
    This study applies large language models (LLMs) to measure technological links and examines its predictive power in the Chinese stock market. Using the BAAI General Embedding (BGE) model, we extract semantic information from patent textual data to construct the technological momentum measure. As a comparison, the measure based on traditional International Patent Classification (IPC) is also considered. Empirical analysis shows that both measures significantly predict stock returns and they capture complementary dimensions of technological links. Further investigation through stratified analysis reveals the critical role of investor inattention in explaining their differential performance: in stocks with low investor inattention, IPC-based measure loses its predictive power while BGE-based measure remains significant, indicating that straightforward information is fully priced in while complex semantic relationships require greater cognitive processing; in stocks with high investor inattention, both measures exhibit predictability, with BGE-based measure showing stronger effects. These findings support behavioral finance theories suggesting that complex information diffuses more slowly in markets, especially under significant cognitive constraints, and demonstrate LLMs’ advantage in uncovering subtle technological connections that traditional methods overlook.
  • 详情 Incentives Innovation in Listed Companies: Empirical Evidence from China's Economic Value-Added Reform
    Innovation is crucial for long-term corporate value and competitive advantage; however, it can misalign the interests of managers and investors. Balancing managers’ short- and long-term goals is a pivotal challenge in promoting innovation incentives. Therefore, this study examines innovative incentives for managers of publicly traded firms to address the issue of agency problems. The study focuses on economic value-added (EVA) reform implemented by China’s State-Owned Assets Supervision and Administration Commission (SASAC), which encourages EVA-driven R&D investments as the primary management metric. The policy effectively motivates key corporate managers by reducing capital costs and stimulating increased innovation. Following this policy’s implementation, notable innovation disparities exist between state-owned enterprises and firms not subject to the reform. Furthermore, innovation incentives significantly affect overconfident company managers, yielding positive effects on innovation.
  • 详情 China International Conference on Insurance and Risk Management

The conference is organized by the China Center for Insurance and Risk Management, School of Economics and Management, Tsinghua University, and co-organized by the School of Finance, Yunnan University of Finance and Economics.
  • 详情 Urban Riparian Exposure, Climate Change, and Public Financing Costs in China
    We construct a new geospatial measure using high-resolution river vector data from National Geomatics Center of China (NGCC) to study how urban riparian exposure shapes local government debt financing costs. Our base-line results show that cities with higher riparian exposures have significantly lower credit spreads, with a one-standard-deviation increase in riparian exposure reducing credit spreads by approximately 12 basis points. By comparing cities crossed by natural rivers with those intersected by artificial canals, we disentangle the dual role of riparian zones as sources of natural capital benefits (e.g., enhanced transportation capacity) versus climate risks (e.g., flood vulnerability). We find that climate change has amplified the impact of natural disasters, such as floods and droughts, particularly in riparian zones, thus weakening the cost-reducing effect of riparian exposure on bond financing. In contrast, improved water infrastructure and flood-control facilities strengthen the cost-reduction effect. Our findings contribute to the literature on natural capital and government financing, offering valuable implications for public finance and risk management.
  • 详情 Positive Press, Greener Progress: The Role of ESG Media Reputation in Corporate Energy Innovation
    The growing emphasis on Environmental, Social, and Governance (ESG) principles, particularly in corporate sectors, shapes investment trends and operational strategies, whose shift is supported by the increasing role of media in monitoring and influencing corporate ESG performance, thereby driving the energy innovation. Therefore, based on reported events from Baidu News and patent text information of Chinese A-share listed companies from 2012 to 2022, this study innovatively applied machine learning and text analysis to measure ESG news sentiment and corporate energy innovation indicators. Combing with reputation, stakeholder, and agency theories, we find that a good reputation conveyed by positive ESG textual sentiments in the media significantly promotes corporate energy innovation, and the effect is mainly realized through alleviating financing constraints and agency problems and promoting green investment. Further analysis shows that ESG news sentiment promotes corporate energy innovation mainly among private firms, non-growth-stage firms, high-energy-consuming firms, and regions with better green finance development and higher ESG governance intensity. From the perspective of ESG news content and information content, greater ESG news attention can also exert an energy innovation incentive effect, in which the incentive effect exerted by positive media sentiment in the environmental (E) and social (S) dimensions, as well as excellent attention, is more robust. This study provides new insights for promoting green and low-carbon development and understanding the external governance role of media in corporate ESG development.
