Objective - The adoption of IFRS aims to reduce the level of information asymmetry. Prior studies conducted in developed countries prove that the adoption of IFRS enhances transparency and diminishes information asymmetry. However, in developing countries with a low level of openness, limited regulation, and more centralized ownership, the ability of IFRS to reduce information asymmetry remains unknown. To address this issue, this study aims to investigate whether IFRS adoption will reduce information asymmetry in some developing countries in South East Asia.

Methodology/Technique - This research is applied in three developing countries: Indonesia, the Philippines and Thailand. Information asymmetry is proxied by the cost of capital using the Easton model (2004) and a bid-ask spread. Listed firms from the three countries are selected as the research sample resulting in 5.313 firm-years for the period between 2007 and 2016.

Findings - This study concludes that the adoption of the IFRS decreases information asymmetry in developing countries. These finding confirm that the benefit of the adoption is the same as in developed countries, despite the level of law enforcement in developing countries being lower. Managers, standard authorities and investors must note that the IFRS conveys benefits to the market, which increases transparency by asking lower returns and valuing company stocks appropriately.

Novelty - This study examines the benefits of the adoption of the IFRS in reducing information asymmetry in some emerging countries to enhance the generalization of the results from prior studies that are mostly conducted in developed countries.
