Several studies show that financial vulnerability is not determined solely by low levels of wealth, but also by behavioural and social factors that shape financial behaviour. From this perspective, the social environment and financial knowledge can influence how investors evaluate their investment experiences. However, most of the literature has focused on how these aspects affect participation in financial markets, rather than on how they shape perceptions of the investment experience itself. This study explores how interactions with one’s social environment and both objective and subjective levels of financial knowledge contribute to how people evaluate the outcomes of their investments. To do so, we analyse a sample of undergraduate students using multivariate regression and Oaxaca–Blinder decompositions across three social environments—family, workplace, and banking advisors—and three types of financial assets: stocks, investment funds, and pension funds. The results show that perceptions of investment experience are shaped not only by individual factors but also by financial knowledge and the social environment—and these effects differ between men and women. There are also differences across types of financial assets, suggesting varying levels of vulnerability. These findings highlight the importance of personal characteristics, financial knowledge, and social context in explaining investment perceptions and differences in financial vulnerability.

This study investigates the roles gold and the US dollar play as safe-haven, hedging, or diversifier assets relating to six important financial stock market indices: the S&P 500, FTSE 100, Hang Seng, CAC 40 (Paris), Shanghai Composite Index, and Nikkei 225. This paper applies the bivariate dynamic copula technique and the DCC-GARCH econometric advanced methods from January 2013 to July 2024 by focusing on four serious market crashes: the Chinese stock market meltdown (2015–2016), the trade war between the US and China (2018–2020), the COVID-19 pandemic (2020–2022), and the conflict between Russia and Ukraine (2022–2024). The results show that the US dollar displays reliable hedging and safe-haven characteristics with strong evidence mainly for its role as a safe-haven asset against the FTSE 100, Hang Seng, and S&P 500. Our findings support the idea that the US dollar serves consistently as a safe-haven asset. In contrast, gold showcased a twofold function, serving as a hedge for the FTSE 100 and the S&P 500 during crisis times and acting as a diversifier for the CAC 40 and the Shanghai Composite Index in times of market stability. This dynamic was specifically noticeable in the COVID-19 period, when gold’s hedging properties were outstanding and its role as a diversifier became more pronounced in the Paris and Shanghai markets. Our results suggest that the consistent reliability of the US dollar as a safe-haven asset combined with gold’s dual role presents a compelling argument for including both in well-diversified portfolios. This strategy enables investors to mitigate risk and safeguard their wealth, especially during periods of financial market volatility. Full article

This study investigates the relationship between stock returns and income inequality in South Africa, a country marked by persistently high levels of income disparities and a sophisticated and structurally unique financial market. Despite the Johannesburg Stock Exchange (JSE) being one of the most developed and liquid markets in Africa, stock ownership remains limited to a small segment of the population, often reinforcing pre-existing income inequalities. This study determines the relationship between stock returns and income distribution using the ARDL bound test methodology. Using time series data from 1975 to 2024, the study examines the extent to which stock market returns influence income distribution. The findings of the study suggest a positive relationship between stock returns and income distribution. This relationship suggests that higher stock market development disproportionately benefits capital holders. The long-term relationship seems to have limited feedback from inequality to stock returns. The findings aim to inform policies on inclusive financial participation and broad-based wealth generation to address South Africa’s structural inequalities. Full article

This study analyzes the relationship between family control and the internationalization of family firms in Mexico. Grounded in the resource-based view and socioemotional wealth theory, it addresses the theoretical problem of how familiness and governance mechanisms influence strategic decisions in emerging markets. Based on 326 observations of family businesses (51) listed on the Mexican Stock Exchange (BMV) from 2009 to 2016, and using a probit regression model, five hypotheses are tested regarding the effects of family directors, board independence, CEO duality, tenure, and ownership concentration on internationalization. The results show that board independence and chair tenure foster internationalization, while ownership concentration and family directors discourage it. The findings contribute to understanding the need for governance reforms that promote more independence and leadership stability to foment internationalization strategies among family businesses in emerging markets.

To address the need for robust investment strategies in an increasingly uncertain global market, this study focuses on an ambiguity-averse insurer facing exchange rate uncertainty while investing in a foreign stock market. The insurer’s surplus is modeled via a classical compound Poisson process, and exchange rate dynamics are captured using an Ornstein–Uhlenbeck process for the drift component. Within the framework of maximizing expected exponential utility of terminal wealth, we derive and solve the Hamilton–Jacobi–Bellman equation to characterize the optimal investment strategy and the associated value function. Finally, a numerical example illustrates how varying model parameters influences the insurer’s optimal investment behavior. Full article

This study examines the portfolio optimization problem of an insurance company that issues an annuity, receives the associated premiums as a lump sum, and invests in a financial market. The insurer’s objective is to determine an investment strategy that minimizes the likelihood of defaulting on annuity payments before ceasing operations, where default occurs if the portfolio value, net of the annuity liability, becomes negative. Unlike the previous work, here the mortality intensity is stochastic and follows a Cox–Ingersoll–Ross (CIR) process. Dynamic programming is employed, and the value function is characterized by a Hamilton–Jacobi–Bellman (HJB) equation, and the former is linearized through the Legendre transform. Numerical results show that default probability declines with higher initial wealth and mortality intensity, while stochastic mortality volatility has little impact—though slightly higher volatility marginally reduces default risk. Optimal stock investment falls with increasing wealth and mortality intensity, and is nearly constant for low wealth levels. Mortality volatility has minimal influence, but a higher Sharpe ratio raises optimal investment, underscoring the role of risk-adjusted returns. Full article

This paper investigates the predictability of stock returns in the Chinese market through the lens of consumption–wealth dynamics within a broader financial system. We focus on two key state variables derived from modern consumption-based asset pricing models: the ratio of log surplus consumption (scr), from the habit-formation framework, and the log consumption–wealth ratio (cay), from the long-run cointegration framework. Using quarterly data from the CSI 300 index between 2012Q1 and 2018Q4, our system-based analysis reveals a horizon-dependent pattern of predictability. The results show that scr is a strong short-term predictor of excess stock returns, reflecting cyclical changes in risk aversion, whereas cay demonstrates superior predictive power over mid- to long-term horizons, consistent with its role as a proxy for long-run expectations. Interestingly, combining scr and cay does not improve predictive performance, suggesting that the economic mechanisms they capture are distinct rather than complementary in the Chinese market. These findings provide evidence on how interconnected macro-financial variables shape stock return dynamics, highlighting the importance of considering temporal horizons when modeling financial systems.

This paper investigates an infinite-horizon optimal consumption and investment problem for an agent who consumes two types of goods: necessities and luxuries. The agent derives utility from both goods but faces a ratcheting constraint on luxury consumption, which prohibits any decline in its level over time. This constraint captures the irreversible nature of high living standards or luxury habits often observed in real economies. We formulate the problem in a complete financial market with a risk-free asset and a risky stock and solve it analytically using the dual–martingale method. The dual problem is shown to reduce to a family of optimal stopping problems, from which we derive explicit closed-form solutions for the value function and optimal policies. Our results reveal that the ratcheting constraint generates asymmetric consumption dynamics: necessities adjust freely, whereas luxuries exhibit downward rigidity. As a consequence, the marginal propensity to consume necessities declines with wealth, while luxury consumption and portfolio risk exposure increase more sharply compared to the benchmark case without ratcheting. The model provides a continuous-time microfoundation for persistent high consumption levels and greater risk-taking among wealthy individuals. Full article

This paper develops a dynamic asset allocation strategy for defined contribution pension funds using a stochastic control framework under the Heston stochastic volatility model. By solving the associated Hamilton–Jacobi–Bellman partial differential equation, we derive optimal equity allocations that adapt to changing market volatility and investor risk aversion using a constant relative risk aversion utility function (parameter $\gamma$). The strategy increases equity exposure during stable periods and reduces it during volatile regimes, capturing both myopic and intertemporal hedging demands. We test the model using historical U.S. data from 2006 to 2025 and benchmark its performance against a traditional static 60/40 stock–bond portfolio, as well as rule-based strategies such as volatility targeting and constant proportion portfolio insurance. Our results show that with moderate risk aversion, the dynamic strategy achieves long-term wealth comparable to the 60/40 benchmark while substantially reducing drawdown risk. As risk aversion increases, drawdown risk is further reduced and risk-adjusted returns remain competitive. Although higher aversion yields lower final wealth, certainty-equivalent returns are highest at moderate aversion levels. These results demonstrate that volatility responsive dynamic policies grounded in realistic stochastic volatility modeling can substantially enhance downside protection and risk-adjusted utility, especially for long-horizon, risk-averse pension participants.

This paper shows that a common form of external habit persistence, despite having much success in asset pricing, implies an extreme degree of conformity in investors’ portfolio choice. If an investor with this utility function uses US aggregate consumption as her external habit benchmark, she has to hold all non-redundant securities contained in the US aggregate wealth portfolio. Even for an investor who uses the average consumption of a more narrowly-defined community as her benchmark, she is still required to hold non-zero positions in all (non-redundant) individual stocks held by any other member of the community. If markets are incomplete, even if an individual investor holds a financial portfolio that conforms perfectly with that associated with the external habit benchmark, it is still impossible for the investor to ensure that consumption exceeds habit in all states of the world. Because of this implication, this form of external habit is unlikely to describe the preferences of individual investors—notwithstanding its success as a model for the representative agent in asset pricing.

Exploring the factors and mechanisms influencing farmers’ participation behavior in formal financial markets is of great significance for improving the rural financial service system and comprehensively promoting the development of rural inclusive finance. Based on the data from the 2020 China Rural Revitalization Survey (CRRS), this paper explores the impact and mechanism of digital skills on farmers’ participation in formal financial markets through the theories of feasibility information, social capital, and technology acceptance. The research results show that digital skills significantly promote farmers’ likelihood and extent of participation in formal financial markets, including stocks, bonds, and wealth management products. This is because digital skills enhance farmers’ information acquisition and online transaction capabilities and broaden their social networks. Heterogeneity analysis reveals that digital skills exert a greater influence on both the likelihood and extent of participation of farmers with lower educational level, farmers in the middle-aged and elderly cohorts, and farmers with low income in formal financial markets. Further research reveals that participating in formal financial markets can significantly increase farmers’ annual income. Therefore, training should be strengthened to enhance farmers’ digital skills. Open information platforms should be established to broaden channels, gradually enabling farmers to freely acquire information, reducing the cost of maintaining social networks for farmers, and improving the convenience of farmers’ online transactions. In addition, efforts should be made to promote the development of inclusive finance, focus on the differentiation issues of farmers in information and wealth, and thereby more widely enhance farmers’ participation in formal financial markets.

Moving beyond Gross Domestic Product (GDP) as the sole measure of economic performance is increasingly critical for addressing the complex challenges of sustainable development. The Inclusive Wealth Index (IWI) offers a more comprehensive framework for assessing long-term sustainability by accounting for changes in produced, human, and natural capital. This paper contributes to this debate by examining the comparative dynamics of these three forms of capital in Greece in relation to European Union averages. Specifically, we employ a repeated-measures design and the mixed ANOVA method to analyse their interactions over time (1990–2020) and across regional contexts. The novelty is to cover the research gap on how the different capitals interact, with Greece serving as a critical case given its environmental vulnerabilities, economic challenges, and position within the European sustainability agenda. The empirical results demonstrate a consistent hierarchy (human > produced > natural), significant growth over time, and pronounced regional disparities, with Western and Northern Europe outperforming Eastern and Southern Europe in overall capital stocks. Moreover, human, produced, and natural capital differed significantly (${\eta }_p^2=0.967)$, with the EU-27 dominated by human and produced capital, while Greece lagged substantially (${\eta }_p^2=0.71$). A robust interaction effect indicated structural divergence (${\eta }_p^2=0.811$). The pairwise comparisons confirmed these results with very large effect sizes (Cohen’s d = 2.3–11.2 in the 95% CI). These findings underscore the importance of moving beyond GDP and highlight the policy relevance of inclusive wealth accounting for ensuring resilience and intergenerational equity. Full article

Determining the optimal portfolio is important in the investment process because it includes the selection of appropriate fund allocation to manage financial risk effectively. Although risk cannot be entirely eliminated, it is managed through strategic allocation based on investor preferences. Therefore, this research aimed to use mathematical models, including the power utility function, the natural logarithm utility function, and a combination of both, to capture varying degrees of risk aversion. The optimal allocation was obtained by analytically maximizing the expected end-of-period wealth utility under each specification, where the investor level of risk aversion was derived by determining the constant. The utility function that failed to produce closed-form solutions was solved through the use of a numerical method to approximate the optimal portfolio weight. Furthermore, numerical simulations were performed using data from two stocks in the e-commerce sector to prove the impact of parameter changes on investment decisions. The result showed explicit analytical values for each utility function, providing investors with a structured framework for determining optimal portfolio weights consistent with their risk profile.

Mainstream strategies for protecting wealth from inflation involve diversification into traditional assets like common stocks, gold, fixed-income securities, and real estate. However, a significant contributor to inflation has been the rising energy prices, which have been the main underlying cause of several past recessions and high inflation periods. Investments in distributed generation with solar photovoltaics (PV) present a promising opportunity to hedge against inflation, considering non-taxed profits from PV energy generation. To investigate that potential, this study quantifies the return on investment (ROI), internal rate of return (IRR), payback period, net present cost, and levelized cost of energy of PV by running Solar Alone Multi-Objective Advisor (SAMA) simulations on grid-connected PV systems across different regions with varying inflation scenarios. The case studies are San Diego, California; Boston, Massachusetts; Santiago, Chile; and Buenos Aires, Argentina. Historical inflation data are also imposed on San Diego to assess PV system potential in dynamic inflammatory conditions, while Boston and Santiago additionally analyze hybrid PV-battery systems to understand battery impacts under increasing inflation rates. Net metering credits vary by location. The results showed that PV could be used as an effective inflation hedge in any region where PV started economically and provided increasingly attractive returns as inflation increased, particularly when taxes were considered. The varying values of the ROI and IRR underscore the importance of region-specific financial planning and the need to consider inflation when evaluating the long-term viability of PV systems. Finally, more capital-intensive PV systems with battery storage can become profitable in an inflationary economy. Full article

This study examines the impact of ESG rating disclosures on the stock performance of highly rated semiconductor companies in Taiwan from 2017 to 2023. The findings reveal significant abnormal returns surrounding ESG rating releases, with positive returns before the event reflecting investor optimism and negative returns afterward indicating market reassessment. The analysis highlights varied effects of ESG dimensions: environmental performance benefits lower-performing firms, social initiatives show negative impacts on high-performing firms, and governance practices demonstrate both short-term costs and long-term benefits. Policy continuity emerges as a critical factor in moderating the financial impacts of ESG performance. Stable and supportive policies enhance the positive effects of ESG initiatives, while inconsistent frameworks exacerbate inefficiencies. These results emphasize the importance of aligning ESG strategies with consistent policy environments to maximize shareholder wealth, offering valuable insights for investors, corporate managers, and policymakers.
