- Determinants of R&D investment under Uncertainty: An Empirical Study of Saudi FirmsPublication . Saif, Abdullah Abdulhafedh Abdullah; An, Nguyen Ngoc Minh; Mohammed, Mohammed Abdeulglel Mansoor; Abduljalil, Abdullah Mohammed Abdulnoor; Altahery , Akram Ali Abdullah; Abdullah, Adam Ali Ahmed; Dawood, Mariam Mourise Saad GhattasThis study aims to examine the financial determinants of research and development (R&D) investment in Saudi industrial firms, with particular emphasis on periods of economic crises. The 2008 Global Financial Crisis and the COVID-19 pandemic are employed as representative examples of major economic shocks to assess firms’ innovation responses. To achieve this objective, the analysis incorporates firm-specific variables using panel data for a sample of thirty industrial firms over the period 2007–2020. The sample selection is based on firms’ strategic engagement in R&D activities and the critical contribution of the industrial sector to the national economy. The dataset, covering fourteen years, was compiled from audited financial statements of the selected firms, obtained from their official websites. The study adopts a purposive sampling approach and an explanatory (causal) research design, employing quantitative data within a multiple regression framework. Using STATA for empirical analysis, the study utilizes one dependent variable R&D investment, measured as the ratio of R&D expenditure to total assets and eight independent variables: cash , sales growth rate, gross profit from sales, return on assets, return on equity, internal financing rate, external financing rate, and the debt-to-equity ratio. The results reveal a statistically significant positive relationship between sales growth rate, gross profit from sales, return on assets, and internal financing, and R&D investment. Conversely, the findings indicate a negative relationship between cash holdings, return on equity, external financing, and the debt-to-equity ratio, and R&D investment.Although crises explains only a small share of R&D variation (R² ≈ 13%), financial variables consistently demonstrate far greater explanatory power ( 87%), confirming that firms’ financial conditions are the key drivers of R&D investment in times of economic turmoil. Finally, the study recommends that Saudi industrial firms adopt optimal business portfolio diversification strategies to reduce exposure to crisis-related risks and mitigate their adverse effects. To enhance their investment portfolios, firms should move beyond traditional income sources and diversify into alternative, non-interest-based revenue streams.
- The Impact of Risk Management Strategies on the Financial Performance of Yemeni Banks under Economic Turbulence: Evidence from 2014–2024Publication . Saif, Abdullah Abdulhafedh Abdullah; Al-mafleh, Mohammed Qasem; Mohammed, Mohammed Abdeulglel Mansoor; Abduljalil, Abdullah Mohammed Abdulnoor; Altahery, Akram Ali Abdullah; IADITIThe prolonged economic turbulence in Yemen has posed significant challenges to the stability and resilience of its banking sector, highlighting the critical need for effective risk governance mechanisms. In this context, the study examines how liquidity, market, credit, and operational risks the core dimensions of risk management affect return on assets (ROA). A balanced panel dataset was constructed from the annual reports of ten banks covering the period 2014 to 2024, selected based on data availability. The analysis employs pooled OLS, fixed-effects, and random-effects estimations, followed by Feasible Generalized Least Squares (FGLS) to ensure robustness. Correlation results indicate positive associations between all risk dimensions and ROA, with operational risk management showing the strongest relationship, followed by market and liquidity risk management, while credit risk exhibits a weaker link. Regression findings consistently confirm that operational, market, and liquidity risk management significantly enhance profitability, with operational risk management exerting the largest effect. Credit risk management demonstrates a positive but statistically insignificant influence, suggesting a more gradual or delayed impact on financial performance. Collectively, these findings highlight that integrated and well-coordinated risk management practices are essential for sustaining profitability in economically fragile environments.
