  • 详情 "Green Tax Reform and the Cost of Equity: Evidence from China’s “Fee-to-Tax” Reform"
    Taking China’s environmental “fee-to-tax” reform as a quasi-natural experiment, this paper employs a difference-in-differences (DID) approach to examine the impact of the green tax reform on firms’ cost of equity on a sample of A-share listed firms from 2012 to 2023. The results show that the implementation of the Environmental Protection Tax Law significantly reduced the cost of equity for heavily polluting firms. This finding remains robust after a series of robustness checks. Analyses of the underlying mechanisms reveal that the green tax reform lowered the cost of equity primarily through the channel of “Porter effect.” Moreover, the effect is more pronounced among firms located in the eastern China, those with stronger internal governance, and those operating in a stricter external monitoring environment.
  • 详情 "The Evolution of China’s Education Finance Structure and Its Implications for Educational Equity"
    In recent years, despite China’s sustained expansion of public investment in education, pronounced regional disparities in educational development persist, revealing the practical constraints of the existing fiscal sharing structure in advancing equity objectives. In particular, the mechanism through which the allocation of fiscal responsibilities between central and local governments influences educational equity performance remains insufficiently examined in a systematic and empirical manner. From the perspective of fiscal structure, this study seeks to identify and explicate the evolutionary trajectory of educational fiscal equity in China, as well as its underlying institutional determinants. To this end, the study constructs a fiscal performance evaluation framework comprising seven core indicators. Objective weights are assigned using the entropy method, and the TOPSIS model is subsequently employed to conduct a comparative ranking analysis of national education fiscal performance over the period from 2013 to 2023. The results indicate that educational fiscal equity has exhibited an overall upward trend during the study period; however, its evolution displays clear stage-specific characteristics. In the initial phase, improvements in equity were primarily driven by fiscal expansion, leading to rapid gains. In the subsequent period, progress became increasingly constrained by structural optimization bottlenecks, with fiscal performance gradually stabilizing at a plateau in more recent years. Further analysis reveals that the persistently heavy fiscal burden borne by local governments, coupled with the relatively limited regulatory and equalization capacity of the central government, constitutes a key structural impediment to the sustained improvement of educational equity. By elucidating the internal mechanism through which the allocation of fiscal responsibilities shapes educational equity performance, this study provides both theoretical grounding and quantitative support for deepening fiscal system reform and optimizing policies related to the allocation of educational resources.
  • 详情 Commodity Risk Mispricing and the Cross-Section of Equity Returns
    We study whether commodity risk is efficiently priced in the cross-section of US equities. We first provide novel evidence on firm-level risk exposure to up to 42 individual commodities. We then construct a mispricing measure as the realized return less the commodity-risk-implied return, and find that it strongly predicts next-month return reversal beyond the traditional short-term reversal. This commodity-risk-mispricing reversal is substantially stronger among small, less analyst- or media-covered stocks, is weakly associated with investor sentiment, and is less prevalent among firms that engage in commodity hedging. In particular, underpricing among these hedgers often remains persistent and even intensifies after the 2004 financialization of commodity markets. This implies that despite the overall decline in mispricing, financialization has likely introduced more costs than benefits for corporate risk management.
  • 详情 Agentic AI Predicts Stock Returns in Real Time
    Can fully agentic artificial intelligence predict equity returns in real time? We build a novel dataset of daily AI-generated attractiveness scores spanning the entire Russell 1000 universe, continuously updated since April 2025. Each trading day, the model freely searches the live internet and produces quantitative scores for every constituent stock before the next market open, eliminating both look-ahead bias and attribution bias. A daily value-weighted portfolio of the 20 highest-ranked stocks earns a Fama-French six-factor alpha of 16.5 basis points per day (41.5% per annum), with an average bid-ask spread of 1.92 basis points. Predictability is sharply asymmetric: the model reliably identifies future outperformers but not future underperformers. The evidence points to stock picking rather than market timing: performance is strongest on down-market days, and the alpha does not come from betting on aggregate market direction. The AI’s reasoning traces help explain this predictability. Alpha is concentrated in traces with richer live-web evidence and stronger analytical structure. In the theme attribution, most active alpha reflects firm selection under an investment lens, not broad theme choice.
  • 详情 Mispricing Factor in China
    This study constructs a new mispricing factor for the Chinese equity market. We propose two-, three-, and four-factor models that incorporate this factor alongside the market, size, and value factors. Our models, especially the two-factor version, consistently outperform the Fama and French models and perform as well as other leading models in explaining Chinese anomalies. This study advances asset pricing literature specific to China and offers a promising new framework for analyzing mispricing in emerging markets.
  • 详情 Macroeconomic Expectations and Expected Returns: Evidence from China
    This paper examines whether subjective macroeconomic expectations predict equity risk premia in China. Using professional macro forecasts from the Wind database over 2011- 2023, we construct a composite macroeconomic expectation index via PLS. We find that the index significantly and positively predicts future equity premia both in-sample and out-ofsample, implying a countercyclical equity premium. The predictive power is robust to a wide range of macro-financial controls and delivers economically meaningful gains in portfolio allocation. Further analysis shows that controlling for forecast errors does not attenuate predictability, and the subjective index largely subsumes the information in realized macro variables, suggesting that it captures forward-looking macroeconomic conditions rather than belief bias. Cross-sectional and long-horizon results reinforce this interpretation.
  • 详情 The Unintended Consequences of Mandatory Reserve Price to Private Equity Placement
    This paper examines whether reserve prices impact the discount on private equity placements (PEPs). Using a sample of auction-based PEPs in China, we find that reserve price discounts are positively associated with bid (offer) price discounts. This inference holds after executing several robustness checks. As extra analyses reveal, the documented impact is ascribed to bidders anchoring on reserve prices. The positive association also depends on bidder identity and anchor-target compatibility. Our evidence ultimately shows that investor wealth benefits from such anchoring biases. Altogether, these findings demonstrate that reserve prices induce bidder undervaluation, thereby resulting in lower offer prices.
  • 详情 Delegation under Risk in IPO Pricing: Evidence from China’s Subscription Reform
    This paper develops a delegation-based framework to explain how institutional design shapes pricing incentives under risk. Using China’s 2016 IPO reform—which abolished prefunding requirements and transferred payment obligations from investors to underwriters—as a natural experiment, we show that introducing subscription-payment risk (SPR) renders underwriter’s partial residual claimants with respect to unpaid allocations. Building on Baron’s (1982) delegation model, we argue that the reform amplifies information asymmetry and induces underwriters to adopt more conservative pricing strategies to manage perceived payment risk. Empirically, IPOs exposed to SPR exhibit greater underpricing and lower offer prices, particularly when investor bids reflect stronger valuation pessimism. The effect tends to be less pronounced for reputable underwriters and when foreign institutional investors participate. Overall, the evidence demonstrates how risk redistribution and institutional frictions jointly shape underwriter behavior and pricing efficiency in primary equity markets.
  • 详情 The Impact of Cross-Border Mergers and Acquisitions on Corporate Performance - Take Chinese listed companies as examples
    With the development of China's economy, more and more Chinese enterprises are active on the world stage, and cross-border M&A is the most effective and fastest way for enterprises to go abroad and make overseas investments, and it is also an important path for globalization after the enterprises have reached a certain stage of growth. Compared to domestic M&A, cross-border M&A is a more complex economic activity, requiring more factors to be considered and greater risks to be taken, with the slightest misstep often leading to operational difficulties for the acquiring company. It is important to consider whether cross-border M&A can improve business performance, the factors that influence the performance of cross-border M&A, and how to improve the performance of enterprises in cross-border M&A. This study takes 100 cross-border M&A events of Chinese listed companies in Shanghai and Shenzhen during the period of 2017-2020 as a sample, and on the basis of reviewing the research results of cross-border M&A at home and abroad, combined with the characteristics of cross-border M&A of Chinese enterprises, from different perspectives, a number of financial indicators are selected to construct comprehensive performance evaluation indicators using factor analysis, and the preliminary analysis shows that after cross-border M&A, the companies with increased performance The preliminary analysis showed that the number of companies whose performance increased after cross-border M&A increased year by year. The impact of industry relevance and transaction equity on M&A performance is not significant; the ratio ofM&A amount to current assets negatively affects firm performance in the year of M&A. Finally, based on the empirical results, relevant policy recommendations are made to encourage better development of private enterprises and improving cross-border M&A performance.
  • 详情 Financializing Compute: The Design of AI Service Trade Markets
    The global AI inference market—reaching approximately $90–100 billion annually and growing at 18% CAGR—operates without organized exchange infrastructure. We document three market failures: resource misallocation (80% of China’s newly built compute capacity sits idle), price opacity (100-fold price dispersion across providers of equivalent quality), and unhedged risk exposure (85% of enterprises miss AI cost forecasts by more than 10%). Following the market design tradition of Roth [2002] and Budish et al. [2015], we propose the AI Service Right (ASR) as a transferable property right on AI compute and the AI Service Unit (ASU) as a quality-adjusted, cross-platform unit of account grounded in hedonic price theory [Rosen, 1974]. The ASU is modality-neutral: billing prices across text, image, video, and speech modalities are unified via eq-token conversion factors (κimg ≈ 2,667 eq-tokens per image; κvid ≈ 2,667 per second of video; κspc ≈ 7 per second of audio), and modality-appropriate benchmark sets (MMLU/HumanEval for language; FID/CLIP Score for image; FVD/CLIPSIM for video; MMBench for multimodal) supply the quality in dex via PCA. We design a hybrid secondary market architecture synthesizing mechanisms from four orthogonal market traditions: foreign exchange markets (cross-platform exchange rates and PPP-analog arbitrage via the ASU); equity markets (Central Limit Order Book, market making, clearing); electricity markets (Compute Locational Marginal Pricing for spatial scarcity signals); and decentralized finance (Automated Market Maker for long-tail liquidity). We establish nine formal propositions: bilateral trading is generically inefficient; Compute Locational Marginal Pricing decomposes nodal prices into system marginal cost, capacity congestion, and bandwidth premia; no-arbitrage equi librium holds with capital constraints (extending Shleifer and Vishny 1997); the ASR market Pareto-improves over bilateral trading; market prices are more in formative under ASR; the hybrid CLOB-AMM architecture weakly dominates either mechanism alone; platform adoption admits multiple equilibria with a coordination trap; financialization may improve or reduce price informativeness depending on speculator-hedger composition; and a hedonic micro-foundation justifies the ASU definition. Calibrated agent-based simulation (500 steps, 30 Monte Carlo runs) provides computational validation: the hybrid architecture reduces price dispersion by 90% relative to bilateral trading, and order-of-magnitude welfare estimates suggest enterprise procurement cost savings of 0.2–20% (net of ASR transaction costs; see Table 7) and potential TFP gains from compute reallocation of up to $29.9 billion annually. We propose a phased implementation roadmap from shadow ledger to full financialization, and we engage critically with the concern that financialization may not reduce intermediation costs [Philippon, 2015].
