This article documents the long-horizon mean reverting character of annual earnings and tests the implications of such mean reversion for security valuation. First, both theory-based and nonparametric measures of earnings persistence decrease as the estimation order increases, revealing 40 percent less long-horizon persistence than expected under the commonly used random walk model. Second, the return responses to the earnings shocks are more closely related across firms to the higher-order measures of persistence that reflect significant long-horizon mean reversion. Third, the persistence measure derived from classical valuation theory outperforms the generic measure in explaining the return responses. Taken as a whole, these results provide evidence for significant mean reversion in the higher-order properties of earnings and for the stock market incorporating these properties in a manner consistent with classical valuation theory. 相似文献

The argument of the "Invisible Hand" is that the system of free enterprise benefits society in general even though it is not the aim of any particular economic agent to do that. This article proposes an analysis of why this is so. The key is that the morality of the market forbids only force and fraud; it does not require people to do good to others. Nevertheless, when all transactions are voluntary to both parties, that is exactly what we can expect to happen. This is both because the sum of the benefits of innumerable transactions, which are beneficial to both parties, is very great, but also and especially because of Positive Externalities. People use the particular products and services they get in market exchanges in ways that benefit others in ways not at all foreseen by the agents to those transactions at the time. These externalities range from the benefits of invention and ingenuity to the exercise of charity and philanthropy, all of which flourish in developed capitalist societies. 相似文献

This paper responds to recent research by Ruland et al. [Ruland, W., Shon, J., Zhou, P., 2007. Effective controls for research in international accounting. Journal of Accounting and Public Policy, 26(1), 96–116.] that addresses the effectiveness of experimental controls for research in international accounting, with focus on Ndubizu and Sanchez [Ndubizu, G.A., Sanchez, M.H., 2006. The valuation properties of earnings and book value prepared under US GAAP in Chile and IAS in Peru. Journal of Accounting and Public Policy 25 (2)]. We attempt to remove some misconceptions about effective experimental controls that have surfaced in the debate. We argue that theory and refined proxies alleviate many of the control issues that have surfaced in the literature. 相似文献
