This study examines the impact of International Financial Reporting Standards (IFRS) on global accounting practices, focusing on financial reporting quality, economic outcomes, and the influence of regulatory and cultural contexts. A mixed-methods approach was employed, combining qualitative interviews with accounting professionals and quantitative analysis of financial statements from various countries. The study investigates the benefits and challenges of IFRS adoption, considering factors such as regulatory environments, cultural differences, and economic development levels. The findings reveal that IFRS’ adoption enhances financial reporting quality by increasing transparency, reducing earnings management, and improving the comparability of financial statements. These benefits are most pronounced in countries with robust regulatory frameworks. However, challenges include high costs and complexities of the transition process, especially for smaller firms and developing countries. Cultural and institutional factors significantly influence the effectiveness of IFRS adoption, with varying impacts across different economic contexts. The study's results underscore the need for supportive regulatory environments and adequate training for accounting professionals to facilitate effective IFRS adoption. Policymakers and regulators should consider tailored approaches to address different countries' challenges. Companies, particularly in developing regions, must plan and allocate resources carefully to manage the transition to IFRS. These insights offer practical guidance for enhancing the effectiveness of IFRS implementation worldwide.
