Abstract

Introduction/Main Objectives: This paper examines the relationship between market uncertainty and asymmetric information in the Indonesian energy sector from 2021 to 2024, using the World Uncertainty Index (WUI) as a measure of global economic and political uncertainty. Background Problems: The study is driven by heightened uncertainty due to major global events such as the COVID-19 pandemic and the Russia-Ukraine conflict, which have introduced significant volatility into the market. Novelty: This research uniquely focuses on the Indonesian energy sector, an underexplored area in global finance, and uses the World Uncertainty Index (WUI) to link global uncertainties with the performance of Indonesia's developing energy market. Research Methods: Employing a regression model, the study investigates the causal relationship between stock market volatility and asymmetric information. Results: The findings reveal that increased volatility negatively impacts market efficiency, indicating that uncertainty and information gaps hinder the market’s ability to fully reflect available information. Conclusion: the study highlights the significant impact of market uncertainty and asymmetric information on stock market volatility and efficiency in Indonesia’s energy sector, offering valuable insights for improving investment strategies and policy formulation in a volatile global environment

Abstract

This study analyzes the effect of green innovation on the default risk of non-financial companies in Indonesia and China during the period 2018–2024. Both countries were selected because they have banking-based financial systems but face different environmental challenges. Default risk is measured using a combined accounting-based approach, namely Altman's Z”-Score, and Zmijewski's ZM-Score. The estimation results using the Fixed Effect Model show that in aggregate, green innovation has no significant relationship with default risk. However, when analyzed per country, the effect of green innovation is proven to be significant and negative on default risk in companies in China, while in Indonesia the relationship is not statistically significant. These findings indicate that the effectiveness of green innovation as a financial risk mitigation strategy is greatly influenced by institutional readiness and national policies. This study provides important insights for policymakers and market players in developing countries regarding the importance of supporting the green innovation ecosystem to strengthen financial stability.
