Can the introduction of a new global standard directly impact the operations of domestically regulated banks before it is enacted through national legislation? This paper explores this question by examining the effects of the Basel III liquidity standard on liquidity creation by U.S. banks. Following the Basel Committee’s endorsement of this standard in December 2010, banks with low liquidity immediately reduced their asset-side liquidity creation by holding more liquid assets. At the same time, these banks increased their liability-side liquidity creation by attracting more deposits through higher deposit interest rates—well before the standard was implemented as domestic regulation in the U.S. These findings provide empirical evidence that enhanced global regulatory cooperation can cause newly established international standards to act as direct and immediate regulatory shocks to domestically regulated financial institutions, even in the absence of national legislation.

A distinctive feature of hedge funds is their dynamic style of trading; hedge funds may shift the investment style in their lifetime. Style shifting is a strategic decision for funds which is beyond the more traditional stock-picking and market-timing carried out at the operational level. This paper tests and validates the performance implications of style-selection skill of hedge funds. Based on the trading style identification through Probabilistic Principal Component Analysis and the measure of style-selection skill developed in this paper, we find that such skill has predictive power for future fund performance, persisting for up to one year. In addition, our findings reveal that funds exhibiting greater style-selection skill enhance the probability of survival. Furthermore, we show that smaller, solo-managed funds operated by managers with longer tenure and higher management fees tend to have greater style-selection skill. Our findings support investors’ decisions when selecting hedge funds. It also opens a new perspective for managerial skills in active money management, reflecting managers’ expertise in data processing about micro and macro information and shocks to achieve success, when considering the investment style.

We introduce a novel GARCH model that integrates two sources of uncertainty to better capture the rich, multi-component dynamics often observed in the volatility of financial assets. This model provides a quasi closed-form representation of the characteristic function for future log-returns, from which semi-analytical formulas for option pricing can be derived. A theoretical analysis is conducted to establish sufficient conditions for strict stationarity and geometric ergodicity, while also obtaining the continuous-time diffusion limit of the model. Empirical evaluations, conducted both in-sample and out-of-sample using S&P500 time series data, show that our model outperforms widely used single-factor models in predicting returns and option prices. The code for estimating the model, as well as for computing option prices, is made accessible in MATLAB language.1

This paper identifies the issue of “duplicate observations” in existing methods for analyzing mutual fund performance and proposes a solution using a novel wild bootstrap-based approach. Our proposed method preserves various characteristics of mutual fund databases, including entry/exit points for each fund (i.e., missing data) and cross-sectional information. We show that our proposed bootstrap tests have a near-optimal size and exhibit greater power compared to widely used standard bootstrap methods for evaluating mutual fund performance. Additionally, we present a new approach to picking the top-performing mutual funds. Our empirical results indicate that a measurable fraction of funds outperform the market.

This study explores how climate-related risk factors influence the European equity and fixed-income markets. We examine the effect of specific physical risk drivers, including temperature fluctuations, drought, floods, wind, and wildfire risk, on both stocks and bonds. Additionally, we assess the impact of transition risk using two potential indicators: the log-returns of futures on European Carbon Allowances and a Transition Risk Index derived from credit default spreads. We also compare them to see if they carry the same information. Our findings reveal that climate risk variables have different effects on stocks and bonds, with stock returns appearing mostly unaffected by climate-related variables. In contrast, bond z-spreads show significant statistical relationships with both physical and transition climate risks. Physical risk, on average, rewards the green bonds in the sample, and penalizes the traditional bonds. As for transition risk, the two proxies are shown to capture different types of information and to affect different bonds. This suggests that credit default swaps are pricing a transition risk that goes beyond carbon emissions.

We find that investor attention significantly increases stock price crash risk. To identify the causal effect, we employ daily repeated quasi-natural experiments where the difference of investor attention is not driven by stock fundamentals, but rather exogenous price rounding issue. This positive effect is more pronounced among firms with higher daily abnormal Baidu search index and higher abnormal small fund inflows ratio, but is mitigated for firms with more sophisticated investors, state-owned enterprise, and firms with relaxation of short-sale constraints. Additionally, we provide supporting evidence that information asymmetry triggered by noise attention serves as a channel through which investor attention amplifies stock price crash risk. Finally, we provide additional evidence illustrating the generalizability of our findings.

This study investigates the dynamic structure of intraday volatility and jump behavior in the Chinese yuan and US dollar exchange market by employing a Gumbel-distribution-based threshold derived from extreme value theory. Using five-minute high-frequency data over 2,450 trading days, we construct a daily jump probability index and examine its responsiveness to major economic shocks, including the U.S.–China trade war and the COVID-19 pandemic. Regression and simulation analyses (5,000 replications) show that the Gumbel-based jump metric provides superior explanatory power in detecting large and irregular jumps. The Gumbel distribution offers a clear and theoretically grounded thresholding mechanism, making it particularly effective in identifying episodic volatility clusters during the 2010s. Tests by Lee and Hannig (2010) and Laurent and Shi (2020) also suggest that the Gumbel jump statistic is more appropriate for capturing the frequent and discontinuous jumps in foreign exchange volatility. Furthermore, after filtering for intraday periodicity, the estimated jump probabilities significantly decline, indicating the importance of periodicity adjustment. This study also confirms that jump probabilities were notably higher during the U.S.–China trade war and the COVID-19 pandemic than in the overall sample period. Sensitivity tests on volatility filtering and simulation parameters further demonstrate the robustness of the Gumbel-based jump distribution.

This paper documents that the dividend payout ratios of larger US banks rise when interest rates increase. To account for this pattern, I develop a model of optimal investment and deposit issuance under a risk-based constraint. Smaller banks primarily generate profits from the Fed funds-deposit spread, which typically widens with higher rates. Larger banks, by contrast, hold a greater share of risky assets and keep government bonds mainly as precautionary buffers. In high-interest-rate environments, these larger banks see only a modest increase in profitability. Consequently, they have weaker incentives to expand their investments and instead opt to reduce their buffer of safe assets to distribute higher dividends. Empirical evidence on payout behavior and leverage across banks that gain different shares of income from government bonds aligns with the prediction of the model. The findings highlight the importance of monitoring banks’ payout and leverage during periods of rising interest rates.

We show that the insider trading pattern on anomaly long-short portfolio stocks can forecast anomaly returns. Specifically, we use the fraction of anomaly long-leg (short-leg) stocks being bought (sold) by insiders as a signal to extract insiders’ information on expected returns of the anomaly. Based on a composite anomaly measure that combines 11 prominent anomalies, we show that the insider trading signal significantly forecasts anomaly returns both in-sample and out-of-sample. These findings also help disentangle the risk-based and the mispricing-based explanations for anomaly returns.
