摘要：Our study provides the first causal test of classical and behavioral asset pricing models that incorporate skewness pricing. In line with these models, our experimental markets show that skewness is systematically priced. Our findings also reveal that positively skewed assets available in small supply exhibit negative expected returns, which is consistent with prospect theory, but not with expected utility models. Furthermore, in line with the mechanism underlying prospect theory, we show that...

摘要：Using confidential microdata, we show that shocks to primary dealers' constraints have significant effects on the U.S. Treasury securities market. We consider two types of constraints: the supplementary leverage ratio and trading desk value-at-risk constraints. In response to tighter constraints, dealers reduce their Treasury positions, triggering a reduction in aggregate turnover and an increase in dealer intermediation margin. Impaired intermediation also amplifies the yield response to net ...

摘要：This paper studies how public information, such as proxy advice, affects shareholder voting and, thus, corporate decision-making. We find that while public information improves the voting decisions of uninformed shareholders, it also induces privately informed shareholders to exit rather than to exercise their voice (vote). As a result, public information impairs information aggregation by voting but improves information aggregation by trading. Overall, public information can undermine corpora...

摘要：Investors face reduced incentives to finance technological change that devalues their legacy investments. We formalize this asset overhang and apply our framework to the climate-banking nexus. Leveraging (1) firm-level data on green innovation and diffusion and (2) the sets of product and technology market peers, we implement a shift-share design that identifies banks' credit facilities impacted by green firm activities. We find that green firms imposing an asset overhang across all lenders ar...

摘要：I study the effect of bond investor demand on the financing and investment decisions of nonfinancial firms using granular data on the bond transactions of insurance companies. Liquidity inflows from insurance premiums combined with insurers' persistent investment preferences identify bond demand shifts in the secondary market. These raise bond prices and reduce firms' financing costs. In response, firms issue more bonds, especially when they have well-connected bond underwriters. The proceeds ...

摘要：We build a novel data set of time-stamped corporate decarbonization commitments-green pledges-for U.S. public firms by classifying news articles with large language models and human validation. Firms announcing green pledges tend to be larger and browner than other firms, both within and across industries. Green pledges significantly raise stock prices, consistent with a reduction in the carbon premium, and predict sizable declines in future carbon emissions and emission intensities. These eff...

摘要：Using a novel measure of investment companies' reliance on generative artificial intelligence (GenAI), we document a sharp increase in GenAI usage by hedge funds after ChatGPT's 2022 launch. A difference-in-differences test shows that hedge funds adopting GenAI earn 2-4% higher annualized abnormal returns than nonadopters, while non-hedge funds do not benefit. The outperformance originates from funds' AI talent and ChatGPT's strength in analyzing firm-specific information. We conduct a new sur...

摘要：This study examines whether mutual fund managers generate alpha through thematic investment strategies that select stocks poised to benefit from specific themes. Using textual analysis of 10-K filings, we identify stocks' thematic exposures and construct each fund's thematic concentration index (TCI) from its holdings. High-TCI funds significantly outperform, with a top-minus-bottom decile spread of 4.26% in annualized four-factor alpha. Managers' thematic expertise is related to their undergr...

摘要：In a monetary union, the risk-free rate cannot adjust to country-level fiscal positions, leaving only default spreads and convenience yields to respond. Empirically, we find that convenience yields explain a large share of the variation in eurozone (EZ) sovereign bond yields. EZ sovereign bonds earn larger convenience yields when their governments run larger surpluses. Since convenience yields generate substantial seigniorage revenue from debt issuance, our estimates imply economically large f...

摘要：Fraud indicators within the Paycheck Protection Program (PPP), a major COVID relief program, are highly geographically concentrated. ZIP codes and counties with high rates of suspicious PPP loans are strongly socially connected, with evidence that fraud spreads spatially over time through social networks. Individuals in suspicious social media groups have higher rates of PPP fraud, and socially connected ZIP codes frequently use the same specific FinTech lenders, consistent with social network...
