Time to clean up environmental liabilities reporting: disclosures, media exposure and market implications
研究了欧洲上市公司环境负债披露的多样性、与媒体关注的关系及市场影响，发现披露水平低但能降低信息不对称。
We investigate firms’ disclosures related to environmental liabilities (EL), how these vary with media exposure, and whether they have information content. Using a sample of European-listed firms reporting under IFRS from 2005 to 2016, we observe diversity in disclosure practices across industries and regions. Although there is an increasing disclosure trend, the level of disclosure of key inputs used to estimate EL (i.e. discount rates and horizons) remains low, with only 35% of firm-years with material EL containing disclosures of both inputs. Furthermore, we test and find that firms facing more media exposure related to environmental matters provide disclosures that are more specific and are more likely to disclose discount rates. Finally, we show that EL disclosure specificity is associated with lower bid-ask spreads following the filing of the annual report and reduced analyst forecast error and dispersion, suggesting specific disclosure reduces information asymmetry.
