Sustainability Reporting and Investors' Perception: Evidence from Selected Sectors in Nigeria

Sat, 07 Feb 2026 22:59:02 +0000

Purpose: The study aimed to investigate the effect of sustainability reporting on investors’ perceptions in Nigeria, specifically examining how environmental, social, and governance (ESG) disclosures influence the Price Earnings (P/E) ratio of listed firms.

Method: An ex-post facto research design was employed using panel data from ten listed firms in the oil and gas and industrial goods sectors between 2015 and 2024. Data were collected from annual reports, sustainability reports, and NGX sources. ESG disclosure indices were constructed and normalized. Panel regression techniques were applied, with the Hausman test supporting the use of fixed effects.

Findings: The results revealed that environmental, social, and governance disclosures had a positive and significant effect on the P/E ratio. The combined ESG model explained 34.56% of the variation in P/E ratios, indicating that sustainability reporting is value-relevant for investors.

Implication: The study recommends that firms enhance the quality of ESG disclosures and that regulators promote standardized reporting practices. Such measures would improve market transparency and strengthen investor confidence in Nigeria’s capital market.

Originality: This research provides empirical evidence from Nigeria, highlighting the direct link between sustainability reporting and investor valuation metrics. It contributes to the literature by demonstrating the relevance of ESG disclosures in shaping investor perceptions in emerging markets.

Purpose: This paper explores the development of accounting information systems (AIS) and the adoption of eXtensible Business Reporting Language (XBRL) in South Korea, with particular attention to their implications for corporate reporting and business sustainability.

Method: A qualitative literature review was undertaken, drawing on scholarly articles and institutional reports identified through targeted keywords. The selected sources encompass empirical studies on XBRL implementation in the Korean capital market, research on AIS development in both large firms and SMEs, and recent works that connect AIS quality with sustainability outcomes.

Findings: South Korea was among the earliest countries to mandate XBRL-based electronic filing through the DART system. Empirical evidence demonstrates that XBRL adoption reduces information asymmetry, lowers equity financing costs, and shortens reporting delays, especially for early adopters. Moreover, Korean firms are modernizing AIS by integrating cloud computing, big data, and artificial intelligence, which enhances efficiency and organizational performance. In addition, recent studies highlight that high-quality AIS contributes positively to sustainability performance through improved information reliability, user satisfaction, and system utilization.

Implication: The convergence of advanced AIS and XBRL reporting establishes a strong digital infrastructure that fosters transparency, accountability, and long-term sustainability. This experience provides valuable insights for other countries, including Indonesia, in developing digital reporting ecosystems.

Originality: By synthesizing diverse strands of literature on AIS and XBRL in South Korea and explicitly linking them to sustainability perspectives, this paper offers an integrated analysis that is useful for students, researchers, and policymakers.

Determinants of Information System Success in the Public Sector: The Moderating Role of Management Support, Tax Complexity, and Locus of Control

Diah Hari Suryaningrum, Pipit Dwi Saraswati — Fri, 15 May 2026 00:00:00 +0000

Purpose: This study aims to examine and analyze the influence of user participation in information system development on system success. Furthermore, it evaluates the role of three contingency factors—top management support, task complexity, and locus of control—as moderating variables influencing this relationship in the context of public services in Indonesia.

Method: The research employs a quantitative approach focusing on employees of the tax service office in Malang Regency. A sample of 50 respondents was selected using a simple random sampling technique via the Slovin method. Data were collected through questionnaires and analyzed using Moderated Regression Analysis (MRA) and subgroup analysis to determine the type of moderating variables.

Findings: The findings indicate that user participation has a significant positive relationship with information system success. All three contingency factors (management support, task complexity, and locus of control) were proven to act as quasi-moderators. Specifically, high management support and an internal locus of control strengthen the relationship between participation and system success. However, unlike previous studies, lower task complexity showed a greater influence on the relationship in this specific study.

Implication: Practically, public sector managers should consider situational factors and individual characteristics before involving users in system development. User participation is not the sole determinant of success; active top management support and an understanding of employees' self-control orientation are crucial for ensuring effective information system implementation to improve public service.

Originality: This study provides empirical evidence on the implementation of New Public Management in Indonesia, particularly within tax service offices. The novelty lies in the finding that task complexity in certain public sector organizations may exhibit different influence patterns on IT success compared to the private sector or organizations in other countries.
