Item Corporate sustainability practices: An interplay of uncertainty, geopolitical risk and competition(Journal of Environmental Management, 2025-03) Bhue, Rajesh; Gartia, Umakanta; Panda, Ajaya Kumar; Tiwari, Aviral KumarThe present study analyses the interplay between uncertainty and sustainability investment in the line of PMC (product market competition), and its impact on the firms' sustainable practices. Based on a sample of 2533 listed companies from 2011 to 2023, it was observed that uncertainty positively influences sustainable investment, and the PMC plays a moderating role in the case of G-20 countries. Furthermore, the research indicates that sustainable investment promotes long-term investment in G-20 countries during the study period and lessens the unfavorable outcome of uncertainty on a firm's value. We employed SGMM (System-generalized method of moments) to concern about the endogeneity issues and for robustness, which was consistent with the empirical results. The study's implications help investors, managers, and policymakers integrate sustainable investment practices with uncertainty alongside pushing sustainable development goals.Item Geopolitical risk and real estate stock crash(Finance Research Letters, 2025-06) Abakah, Emmanuel Joel Aikins; Abdullah, Mohammad; Akinsomi, Omokolade; Tiwari, Aviral KumarWe investigate the effect of geopolitical risk (GPR) on real estate stock crashes while accounting for the impact of cash holdings and financial constraints in this relationship. Using a dataset from 28 countries covering the period of 2000 to 2023 from 1805 firms, we document that geopolitical risk increases real estate stock price crash risk. Our result remains consistent using an alternate proxy of geopolitical risk and even after considering endogeneity concerns using 2SLS and Entropy balanced samples. Our result shows the negative impact of GPR is stronger for firms with high cash holdings and high financial constraints.Item Novel approaches to model decomposed oil shocks, geopolitical risk, clean and fossil fuel stocks(Borsa Istanbul Review, 2025-05) Dam, Mehmet Metin; Altıntaş, Halil; Tiwari, Aviral KumarThis study examines how oil supply, demand, and risk shocks, along with geopolitical risks, impact the performance of clean and fossil fuel stocks. Using daily data from March 2014 to January 2022, advanced methods like wavelet quantile correlation (WQC), cross-quantilogram (QC), and nonparametric causality-in-quantile (NPCQ) are applied. The results reveal significant volatility linkages between clean and fossil fuel stocks, with oil shocks and geopolitical risks influencing financial markets. Demand and risk shocks act as transmitters, while supply and geopolitical risks are receivers of spillovers. Clean energy stocks are net transmitters of spillovers, while fossil fuel stocks show mixed profiles. Fossil fuel stocks act as safe havens in the medium term, while clean energy stocks exhibit this in the long term. Geopolitical risks have little effect on clean energy stocks, indicating their resilience. The study highlights the importance of real-time monitoring for managing market fluctuations.
