Compared to previous literature on external FinTech, this paper is more interested in the role played by bank FinTech. Based on panel data from Chinese commercial banks spanning 2010 to 2021, this paper investigates the impact of digital transformation on bank soundness and its potential mechanisms. The empirical findings demonstrate a positive association between digital transformation and bank soundness, driven primarily by strategic and management digitization. Mechanistic analysis indicates that digital transformation improves bank soundness by mitigating risk-taking behavior and promoting diversification. The positive effect of digital transformation is more pronounced in state-owned and joint-stock banks, banks with higher liquidity mismatch as well as in sub-samples with greater levels in external FinTech development and economic policies uncertainty. Additional analysis suggests that digital transformation can still enhance bank soundness even in the presence of relatively easy monetary and macroprudential policies, highlighting the harmonization and complementarity between internal innovation from digital transformation and external regulatory policies in maintaining banking stability. Overall, this paper contributes to the literature on bank FinTech, factors influencing bank stability. And it also provides a novel explanation for the relationship between financial innovation and financial stability.

Biodiversity conservation incurs substantial economic costs. We investigate how financial markets price the risks such costs induce, exploiting the “Green Shield Action,” a major regulatory initiative launched in China in 2017 to enforce biodiversity preservation rules in national nature reserves. While improving biodiversity, the initiative led to significant increases in bond yields for municipalities with these reserves. The effects are driven by increases in local governments’ fiscal risk due to expected increases in transition costs resulting from shutting down illegal economic activities within reserves and additional public spending on biodiversity. Investors show little non-financial consideration towards endeavors counteracting biodiversity loss.

This paper analyzes the amplification characteristics of risk propagation in multi-layer financial networks from the perspective of network topologies. The research finds that, even without feedback pathways, cross-layer links alone can lead to more severe risk contagion than in single-layer networks. More importantly, with increasing connectivity, the formation of cyclic structures in multi-layer networks will significantly exacerbate the systemic risk.

In the pursuit of knowledge, research philosophy serves as the uncharted compass guiding scholars through intellectual terrain. This meticulously crafted review paper embarks on an enthralling odyssey through the annals of history and the corridors of thought. We trace the origins of research philosophy in ancient civilizations, witness the dynamic interplay of faith and reason during the medieval and Renaissance periods, and explore the Enlightenment era's embrace of reason and empiricism. The ascent of positivism in the 19th and 20th centuries reshapes the landscape, followed by the seismic shifts of postmodern critiques and paradigm shifts. As we journey through time, we also embrace the contemporary and cross-disciplinary influences that enrich the philosophical fabric of modern research. This narrative underscores the profound impact of philosophy on research practices, offering readers a captivating tapestry interwoven with intellectual discoveries. Join us on this voyage through the epochs and ideologies that have shaped the pursuit of knowledge.

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.

We examine how Federal Open Market Committee (FOMC) meetings influence international stock returns, highlighting that the standard Fed news channel creates an even-week pattern in the United States and other highly integrated developed markets. By analyzing the Chinese market, we demonstrate that the news channel contributes to higher returns, operating in non-US countries even without international equity flows. Additionally, we identify an uncertainty channel that produces a contrasting odd-week pattern. Placebo tests indicate that the effectiveness of the uncertainty channel may depend on the financial market’s openness. Overall, our research enriches and extends the existing view on how the Federal Reserve, as the leader of central banks, shapes international stock market returns throughout the entire FOMC cycle.

We examined reference point adaptation following gains or losses in security trading using participants from China, Korea, and the US. In both questionnaire studies and trading experiments with real money incentives, reference point adaptation was larger for Asians than for Americans. Subjects in all countries adapted their reference points more after a gain than after an equal-sized loss. When we introduced a forced sale intervention that is designed to close the mental account for a prior outcome, Americans showed greater adaptation toward the new price than their Asian counterparts. We offer possible explanations both for the cross-cultural similarities and the cross-cultural differences.

This paper explores the factors that influence redistributive preferences in the context of significant economic transformation, focusing on the transition premium and growth. Using an online survey experiment with a nationally representative sample from China, we find that priming getting rich via relatively less meritocratic, yet representative ways under market transition in post-reform China reduces redistributive support, specifically for policies that aim to take from the rich and the belief in the government’s duty to redistribute, indicating the presence of a set of fairness views in China that deviate from the conventional meritocratic paradigm. Heterogeneous treatment effects analyses reveal that such non-meritocratic fairness views are a general phenomenon, and self-interest in the form of subjective economic pressure only serves as a secondary concern. While people feel that the rich are more deserving and demand less redistribution regardless of subjective economic pressure, only those under less economic pressure exhibit decreased support for policies that aim to help the poor. These representative ways of getting rich under market transition are similarly fair compared to winning a lottery, far less fair than a self-made entrepreneur, but much more legitimate than acquiring wealth through corruption. Priming China’s growth story does not result in statistically significant changes in redistributive support. Additionally, we rule out the influence of three relevant confounders: low tax salience, preference falsification under authoritarianism, and misperceptions about relative income positions and intergenerational occupational mobility. We argue that such non-meritocratic fairness views are particularly salient in societies that break away from a centrally-planned economic system in the past and transition towards a high-growth market economy, where economic opportunities are becoming more inclusive.

Based on 31 provinces, municipalities, and autonomous regions in mainland China, this paper explores the temporal and spillover effects of the provincial COVID19 pandemic on stock returns. The results show that stock returns are significantly and negatively correlated both with the pandemic in the firm’s headquartered province (referred to as, local province), and the pandemics in other provinces (referred to as, non-local provinces). By multiple time dimensions analysis, we find that at the weekly (monthly) level, the impact of the pandemic in local province on stock returns is larger (weaker) than the pandemics in non-local provinces, showing the temporal (spillover) effects. Mechanism analysis shows that COVID-19 can quickly reduce investors’ attention to stock market. The heterogeneity analysis shows that firms owned by state, with bad CSR, or a higher proportion of shares held by the largest shareholder are more affected by COVID-19. After replacing samples and time intervals, the results remain robust.

Quantum theory provides a comprehensive framework for quantifying uncertainty, often applied in quantum finance to explore the stochastic nature of asset returns. This perspective likens returns to microscopic particle motion, governed by quantum probabilities akin to physical laws. However, such approaches presuppose specific microscopic quantum effects in return changes, a premise criticized for lack of guarantee. This paper diverges by asserting that quantum probability is a mathematical extension of classical probability to complex numbers. It isn’t exclusively tied to microscopic quantum phenomena, bypassing the need for quantum effects in returns.By directly linking quantum probability’s mathematical structure to traders’ decisions and market behaviors, it avoids assuming quantum effects for returns and invoking the wave function. The complex phase of quantum probability, capturing transitions between long and short decisions while considering information interaction among traders, offers an inherent advantage over classical probability in characterizing the multimodal distribution of asset returns.Utilizing Fourier decomposition, we derive a Schr¨odinger-like trading equation, where each term explicitly corresponds to implications of market trading. The equation indicates discrete energy levels in financial trading, with returns following a normal distribution at the lowest level. As the market transitions to higher trading levels, a phase shift occurs in the return distribution, leading to multimodality and fat tails. Empirical research on the Chinese stock market supports the existence of energy levels and multimodal distributions derived from this quantum probability asset returns model.
