The Impact of Mandated Cash Flow Disclosure on Bid‐Ask Spreads
研究发现澳大利亚强制要求披露现金流量表后，公司股票买卖价差缩小，尤其对现金流估算不准的公司效果更明显，说明强制披露降低了市场信息不对称。
Abstract: This study provides evidence that mandatory cash flow disclosure required by Approved Australian Accounting Standard AASB 1026, Statement of Cash Flows (June 1992) was associated with a decline in bid‐ask spreads following the introduction of the regulation, even after controlling for changes in trading volume and price volatility. More pronounced decreases in bid‐ask spreads were associated with firms having lower correlations between reported CFO and estimates of CFO using balance sheet reconstructions. We conclude that mandatory cash flow disclosure reduces information asymmetry across market participants.
