et valuation, property, plant and equipment (PPE), goodwill, and research and development expenditure on bankruptcy risk, proxied by the Altman Z-score, among publicly listed companies in ASEAN countries. The study employs a quantitative approach using secondary data obtained from 1,354 non-financial firms listed in Indonesia, Malaysia, Thailand, Singapore, and the Philippines over the 2015–2023 period, yielding a total of 7,726 firm-year observations. Data were analyzed using a fixed-effects panel regression model. The findings reveal that asset growth and goodwill exert a positive and significant effect on the Altman Z-score, whereas research and development expenditure has a negative and significant effect. Revenue growth demonstrates a marginally positive influence, while market valuation and PPE do not exhibit a significant effect on bankruptcy risk. These results suggest that corporate financial stability is determined not only by financial factors but also by the quality of strategic resources and firms’ adaptive capabilities. The novelty of this study lies in the integration of the Resource-Based View and Dynamic Capabilities Theory perspectives into a bankruptcy prediction framework for publicly listed companies across ASEAN countries.

gn direct investment (FDI) and political stability (PS) on economic growth in member countries of the Organization of Islamic Cooperation (OIC). The study utilizes panel data from 30 OIC member countries over the period 2005–2023, sourced from the World Bank’s World Development Indicators (WDI). The analytical method employed is panel data regression using the Fixed Effect Model (FEM) to control for individual heterogeneity across countries, as well as Moderated Regression Analysis (MRA) to test the moderating role of PS in the relationship between FDI and economic growth. The estimation results show that both TO and FDI have a positive and significant impact on economic growth. However, the interaction between FDI and PS exhibits a negative and significant effect, which contradicts conventional theoretical expectations that political stability should enhance the positive impact of FDI. These findings suggest that in several OIC countries, despite relatively low political stability, FDI continues to flow in response to economic opportunities, strategic interests, or domestic market appeal. In other words, political instability does not always serve as a major barrier to foreign investment, especially when the economic potential remains high. Moreover, FDI under such conditions may serve as an important instrument to strengthen international economic cooperation, expand production capacity, and drive long-term economic growth. These findings provide strategic implications for the formulation of investment and institutional stability policies in OIC countries.
