Financial reporting and firm valuation: relevance lost or relevance regained? created byLuzi Hail

In this study, I examine whether balance sheet and income statement numbers have lost or regained their relevance over the last 30 years. Institutional and macroeconomic factors like the global trend towards strengthening regulation and harmonising financial reporting, the extended use of fair values over historical cost, and the recurring occurrence of accounting scandals, market bubbles, and financial crises make it likely that the role of financial reporting for firm valuation has changed. Following prior research, I estimate four models for the concurrent relation between market value and accounting numbers, and then examine the pattern in explanatory power over time. I find that the loss in relevance of the income statement continues in recent years and is present in a large international sample, in particular in countries with strong institutions. While the overall relevance of the balance sheet remains stable, I find a downward trend during the first sample half, which reverses in the second half, especially in common law countries with strong investor protection, strict disclosure requirements, and integrated markets. Even though several caveats apply, the results suggest that changes in the economy, the institutional environment, and in how firms operate affect the relative importance of accounting information for the use in firm valuation by outside stakeholders.
