The irrational feedback trading behavior in the crude oil markets remains puzzling for academic communities and market professionals. This study explores the time-varying features of feedback trading in the four major crude oil futures markets. We find the popularity of positive feedback trading in the WTI, Brent and DME Oman futures markets, and that of negative feedback trading in the China SIEE futures market. However, substantial oscillations of feedback trading strategies occur over time, where positive and negative feedback trading strategies cluster during miscella- neous market crises. Further, risk aversion plays a dominant role in the dynamic mean and volatility transmissions with feedback trading in most of the crude oil markets. The dominance of risk aver- sion is more pronounced during the tumultuous periods such as GFC and COVID-19 pandemic. Our findings render important implications for investors on containing irrational feedback trading.

In Chinese culture, the Zodiac Year (“Benmingnian”) is widely regarded as inauspicious, reflecting a deep-rooted superstition that shapes risk perception and decision-making. Using data on 2,194 Chinese listed firms between 2003 and 2022, this study investigates whether chairpersons’ Zodiac Year superstition affects outward foreign direct investment (OFDI) strategies. We find that firms pursue more conservative OFDI strategies during the chairperson’s Zodiac Year—diversifying across more projects while reducing the size of individual investments—consistent with heightened risk aversion. The effect is amplified under greater operational uncertainty but weakens in firms with stronger formal institutional constraints, such as state ownership or political connections. It also weakens in regions more deeply shaped by Confucian traditions—a rational informal institution that curbs superstitious tendencies—and varies systematically with managerial characteristics such as gender and education. Overall, the findings reveal how culturally embedded, nonrational beliefs shape strategic decision-making in international business.

Whether risk aversion is time varying and countercyclical is central to modern asset pricing, yet evidence remains limited and is based mainly on experimental, survey, or aggregate stock market data. We provide individual-level evidence from 10 million Chinese auto insurance contracts from 2011 to 2017, estimating policyholders’ risk aversion from deductible choices. We find that risk aversion is time varying and countercyclical. The estimates are negatively related to lottery and stock trading, positively related to insurance sales and bond trading, and vary with psychological factors, including seasonal mood, “zodiac year,” and calendar events.

This paper utilizes the COVID-19 pandemic as an exogenous shock to investor uncertainty and examines the effect of uncertainty on stock liquidity. Analyzing data from Chinese listed firms, we find that stock liquidity dries up significantly in response to an increase in uncertainty resulting from regional pandemic exposure. The underlying reason for the decline in stock liquidity during the pandemic is a combination of earnings and information uncertainty. Funding constraints, market panic, risk aversion, inattention rationales, and macroeconomics factors are considered in our study. Our findings corroborate the substantial impact of uncertainty on market efficiency, and also add to the discussions on the pandemic effect on financial markets.

This paper develops an SOE (small open economy) dynamic general equilibrium model to study the impact of climate change on the current account. By calibrating the model to Chinese economy, we find the following results. First, the current account-output ratio improves in the first decade following an increase in global temperature caused by climate change. It then deteriorates in the following next three decades. Second, the overall current account-output ratio dynamics in response to climate change is neither affected by the types and stringency of climate policies, nor by the levels and growth rates of temperature increases. Third, the impact of an increase in temperature from 1.28 ℃ to 1.5 ℃ relative to the pre-industrial periods (1850-1900) on the current account-output ratio is equivalent to that of an approximate 0.14% permanent decline in TFP. Finally, although the current account-output ratio is likely to deteriorate in the first year when temperature increases instantly, it might not be true if the coefficient of relative risk aversion, or interest rate premium is larger, or debt sensitivity to interest rate is smaller.

Using data from Chinese A-share listed firms from 2015 to 2022, we employ a difference-in-differences model to empirically examine the impact of bankruptcy regimes, marked by the establishment of bankruptcy courts, on firms’ total factor productivity (TFP). The results show a significant decline in TFP among firms in regions following the establishment of bankruptcy courts. This finding remains valid after a series of robustness tests. Mechanism tests reveal that establishing bankruptcy courts increases firms’ risk aversion incentives by endowing creditors with excessive rights. Consequently, firms tend to reduce liabilities, curtail R&D investment, and accumulate liquid assets as coping measures, ultimately contributing to a decline in TFP. Furthermore, this effect is more pronounced for firms with high financial risk. However, the improvement of the market mechanism can alleviate the negative impact of bankruptcy courts excessively strengthening creditor protection. Specifically, when firms are located in regions with weak government intervention and strong financial development, as well as in market environments with low uncertainty and strong competition, this negative impact can be mitigated. These findings provide fresh insights into the dual nature of creditor protection and offer valuable references for governments to improve the bankruptcy legal system.

This study explores the relationship between board chairs' early-life experience in the Great Chinese Famine and the debt maturity choices made by Chinese listed firms between 2000 and 2017. Our findings indicate that board chairs with famine experience exhibit a propensity towards long-term debt usage. We argue that this finding can be attributed to a risk-averse rather than altruistic orientation among board chairs who have experienced famine. Our results are particularly salient for firms with lower asset redeployability, higher distress risk, no political affiliations, and those that are not stateowned enterprises. Furthermore, this study provides three analyses to support the risk aversion traits: (1) board chairs with disaster experience underestimate their company's profit potential, (2) board chairs located in areas with higher mortality rates exhibit more obvious risk aversion behavior, and (3) extending the debt maturity date, board chairs can effectively increase company investment and mitigate the underinvestment problem.

Starting from the change in decision-makers’ risk attitude, which suggests “an increase in risk leads to a heightened tendency for risk aversion”, this study explores the nonlinear relationship between idiosyncratic risk and corporate cash holdings. Empirical analysis results indicate that, with the enhancement of decision-makers’ risk-averse degree, the marginal increase in corporate cash holdings presents an upward trend as idiosyncratic risk rises. Associated with the changes in managers’ risk attitude, the nonlinear relationship between idiosyncratic risk and corporate cash holdings becomes insignificant when the firm purchases directors’ liability insurance or is located in regions with better business environments. However, if the executives are older or hold academic titles, the increase in corporate cash holdings with the rise of idiosyncratic risk is more rapid.
