ABSTRACT
We aim to investigate the impact of the adoption of the International Financial Reporting Standards (IFRS) on a firm’s strategic voluntary disclosure decisions under different product market conditions. In the corporate world, firms tactically decide the level of voluntary disclosures considering their benefits, like resolving information asymmetry in the financial market, and costs, like providing proprietary information to their rivals. The adoption of IFRS has affected the demands in the financial market for complementary information, and therefore, it would affect the incentive to withhold corporate information in consideration of proprietary costs in the product market. Using a sample of Korean firms, we find that the likelihood of withholding management forecasts in concentrated industries is weaker in the post-IFRS adoption phase than in the pre-IFRS adoption phase. This is because there are greater demands for corporate disclosures for firms in concentrated industries in the post-IFRS adoption phase than earlier. Moreover, we find that the influence of IFRS on the decision of firms in concentrated industries to disclose management forecasts is significant only for firms with higher market power and higher financial leverage.

Notes
1 Referring to Verrecchia (Citation1983), the disclosure-related costs include the costs for preparing and disseminating information and proprietary costs.
2 Many related studies set sample periods to include one to five years before and after adopting IFRS (Ahmed, Neel, and Wang Citation2013; De George, Li, and Shivakumar Citation2016; Key and Kim Citation2020; Kwon, Na, and Park Citation2019; Li and Yang Citation2016; Rhee, Yoo, and Cha Citation2016).
3 In our sample, 13% (9% and 3%) firm-years have sales (operating income and net income) forecasts.
4 We estimated the alternative regression model, EquationEquation (2)(2)
(2) , which only includes the control variables that show the statistically significant association with the likelihood of releasing management forecasts. The test results for H1 to H3 are consistent to the results reported in subsection 4.2. The coefficients on the variable of interest, INDCON*IFRS, are overall larger than those on the main tests, and Max-rescaled R2s are slightly smaller than those of main tests.
5 We conduct the same analyses in testing H2 and H3. In testing H2, we find the supporting evidence only when the event years are set to 2011 and 2012. In testing H3, we find the supporting evidence only when the event year is set to 2011. These are untabulated for a simple documentation.
