This paper examines how the geographical locations of shareholders in mutual fund management companies influence fund investment decisions and performance in China. Using a hand-collected sample comprises 3610 mutual funds managed by 143 fund management companies from 2010 to 2021, we employ a double-clustering methodology to demonstrate that mutual funds are significantly more likely to hold and overweight stocks from regions where their management company's shareholders are located. These regionally aligned holdings generate superior returns and contribute meaningfully to overall fund performance, particularly in stocks with high information asymmetry. The findings suggest that shareholders provide informational advantages that shape portfolio choices, offering new insights into the origins and consequences of local bias in institutional investment.

Contagion risk has garnered widespread attention with the major occurrence of financial crises. However, existing literature has mainly focused on the characteristics analysis of risk contagion, while ignoring the prediction of contagion risk. Therefore, considering the importance of time series charts, a framework for contagion risk prediction is proposed by comprehensively mining the features of technical charts and technical indicators. In detail, correlation and centrality of the financial network are extracted to specify the contagion risk. Then, time series charts are converted to graphs by the chart similarity, and each node in the graph is assigned with technical indicators. Finally, a Chart Graph Convolutional Network (Chart GCN) is used to extract the features in the graph and predict the contagion risk. Based on the 28 sectors of the Chinese stock market, we specify the contagion risk and verify its consistency with the occurrence of financial crisis. In addition, our model proves the effectiveness of mining time series chart features in stock market contagion risk prediction. These results are essential for risk management in the financial market.

This paper proposes an explainable machine learning model for consumer credit scoring in Mexico, an emerging economy. We develop an extreme gradient boosting (XGBoost) model using non-traditional data from the Financial Inclusion National Survey. To address the black box problem, we explore the feature importance by estimating the Shapley values that measure the average marginal contributions across all possible subsets of features. The key drivers of consumer credit defaults include the adverse economic effects due to the COVID-19 pandemic and financial attitudes and behaviors. By exploring the distributions of the Shapley values by age and income, we find evidence of non-linearity in the feature explanations.

We examine the relationship between net revaluations of foreign currency-denominated assets and liabilities and banks' liquidity creation. Our findings reveal a significant effect on FX-USD liquidity creation: revaluations enhance liquidity creation on the asset side but diminish it on the liability side, leading to a total neutral effect. Subsample analysis reveals that banks with positive FX mismatches face liquidity destruction in FX-USD liabilities during exchange rate shocks, whereas negatively FX-mismatched banks use these shocks to extend long-term FX loans, balancing total liquidity creation. For accounts denominated in the domestic currency, no significant effects of net revaluations are observed for liquidity creation on the full sample. For positively FX-mismatched banks net revaluations enhance total liquidity creation, while for negatively FX-mismatched banks reduce it, resulting in an overall neutral outcome for domestic currency liquidity creation. Furthermore, regulatory capital moderates the impact of revaluations on liquidity creation through the financial fragility mechanism. These results underscore the complex interplay of currency risks, balance sheet FX mismatches, and regulatory dynamics in influencing liquidity creation in emerging markets.

The energy transition and the climate policies accompanying it represent one of the major challenges for the Russian economy. Using a CGE model and a firm-level financial model, we evaluate transition risks for Russia's financial system. Our analysis reveals that the main costs to Russia from global net-zero efforts are largely exogenous, stemming from a decline in the value of its energy products rather than from domestic climate policies. Moreover, the effects of global climate actions in the Net Zero scenario exceed those of implementing a domestic emissions trading system aligned with Russia's low-carbon development strategy. The granular data in the satelite financial models makes it possible to evaluate the concentration of sectoral debt burden and estimate the impact of climate regulations on sectors' equity valuations.

This study examines Polish households with variable-rate domestic currency mortgages during the 2022 - mid-2023 interest rate shock. Using a unique dataset and econometric modelling, it identifies financial-economic, socio-demographic, and attitudinal characteristics of households that experienced delayed instalment repayments. These difficulties were primarily associated with households' financial-economic features, particularly broader financial constraints and deteriorated living standards. A strong association with the Mortgage Service-to-Income (MStDI) ratio underscores its relevance as a key indicator of financial vulnerability among the analysed households under stress. The findings offer directions for further research and institutional reflection aimed at developing consumer protection policy.

The Limited Partnership Agreement (LPA) enables flexible ownership structures for actual controllers. This study examines the impact of the LPA structure on labor investment efficiency among Chinese listed firms from 2014 to 2021. We find that firms with LPA structure exhibit 21.53% higher inefficient labor investment compared to those without LPA structure, with the effect driven by principal-agent conflicts and information asymmetry. More specifically, we find that the impact of the LPA structure on labor investment efficiency is manifested through staffing imbalances. In addition, the negative effect is more pronounced among firms with weaker corporate governance, higher labor adjustment costs, and higher human capital intensity. Our results also reveal that the LPA structure increases the stickiness of labor costs. Overall, the findings indicate the governance risks of partnership-based ownership and provide practical guidance for optimizing labor investment through ownership design.

This study estimates the causal effect of housing wealth appreciation on happiness by exploiting a policy-induced discontinuity in housing value based on house size. Using regression discontinuity analysis of nationally representative household survey data, we find that housing wealth appreciation significantly improves individual happiness. We also find the impact is more pronounced among females, stronger for young households than older ones, and more significant for liquidity-constrained households. These findings highlight housing wealth as a key determinant of happiness, offering important insights for policymakers seeking to improve citizen well-being through housing market policies.

Recent research on the tax avoidance preferences of family firms has yielded mixed results. We address this by examining tax avoidance behaviour in the Indian market, a unique setting characterised by concentrated family ownership and comparatively weak investor protections. Our findings show that family firms engage in less tax avoidance than non-family firms, particularly when descendant family members serve as chairpersons or CEOs. We further identify a U-shaped association between family ownership and tax avoidance: moderate family ownership reduces avoidance through alignment effects, whereas very high ownership fosters entrenchment and greater avoidance. Subsample analyses reveal that the negative association between family ownership and tax avoidance holds only under low competition and limited market growth. In highly competitive and high-growth environments, external pressures outweigh family-specific concerns. Overall, our findings enrich the understanding of family firms' tax behaviour in emerging markets and offer important implications for governance, investor protection, and tax policy.

Marriage can profoundly shape a chairperson's risk preferences and managerial capabilities. Drawing on social network theory and the theory of diversity cascades across organizational hierarchies, we investigate the impact of intra-country migrant marriage on family firms' research and development (R&D) investment. Analyzing panel data from Chinese family firms spanning 2008 to 2020 reveals that intra-country migrant marriage significantly increases R&D investment. However, this effect weakens under high market and policy uncertainties. Mechanism analysis supports both a direct effect through expanded social networks and an indirect effect via top management team diversity. Heterogeneity analysis further reveals that the effect weakens only when the chairperson's blood relatives are involved in the firm's management or in regions with well-developed labor markets, whereas it is more pronounced in regions characterized by advanced technology markets.
