Abstract
We examine the cost-effectiveness, from the shareholders' perspective, of the accounting standards issued by the FASB during 1973-2009. We evaluate (i) the stock market reactions of firms affected by the standards surrounding events that changed the standard's probability of issuance; and (ii) whether the market reactions are related, in the cross-section, to agency problems, information asymmetry, proprietary costs, contracting costs, and changes in estimation risk. The average standard is a non-event from the investors' perspective because 104 of the 138 standards examined are associated with no change in shareholder value. 19 (15) standards are associated with a decrease (increase) in shareholder value. Surprisingly, 25 standards are associated with an increase in estimation risk. In the cross-section, firms with higher levels of information asymmetry, lower contracting costs, and a decrease in estimation risk experience most positive returns.
