Information Asymmetry, R&D, and Insider Gains

Although researchers have documented gains from insider trading, the sources of private information leading to information asymmetry and insider gains have not been comprehensively investigated. We focus on research and development (R&D)-an increasingly important yet poorly disclosed productive input-as a potential source of insider gains. Our findings, for the period from 1985 to 1997 indicate that insider gains in R&D-intensive firms are substantially larger than insider gains in firms without R&D. Insiders also take advantage of information on planned changes in R&D budgets. R&D is thus a major contributor to information asymmetry and insider gains, raising issues concerning management compensation, incentives, and disclosure policies.

Fundamental Information Analysis

Fundamental analysis is aimed at determining the value of corporate securities by a careful examination of key value-drivers, such as earnings, risk, growth, and competitive position. In the context of such analysis, we identify below a set of financial variables (fundamentals) claimed by analysts to be useful in security valuation and examine these claims by estimating the incremental value-relevance of these variables over earnings. Our findings support the incremental value-relevance of most of the identified fundamentals; in fact, for the 1980s, the fundamentals add approximately 70%, on average, to the explanatory power of earnings with respect to excess returns. We also show that the returns-fundamentals relation is considerably strengthened when it is conditioned on macroeconomic variables, thereby demonstrating the importance of a contextual capital market analysis. For example, several fundamentals that appear only weakly value-relevant or even irrelevant in the unconditional analysis exhibit strong association with returns under specific economic conditions (e.g., the accounts receivable and the provision for doubtful receivables signals during high inflation). From a general examination of the role of fundamentals in security valuation we turn to the related issues of earnings persistence, growth, and the earnings response coefficient. We hypothesize that the funda-

Some economic determinants of time-series properties of earnings

Abstract The earnings ‘time-series literature’ in accounting focuses on the statistical characteristics of the processes which generate corporate earnings. In order to further our understanding of earnings behavior, this study investigates the question whether inter-firm differences in these statistical characteristics (autocorrelations and variances of earnings changes) can be explained by economic factors. Various relationships between economic factors and earnings behavior are derived from the economic literature and examined empirically in this study. Findings indicate that autocorrelations and variability of annual earnings and earnings over equity changes are systematically associated with the following factors: the type of product, the height of industry barriers-to-entry (a surrogate for degree of competition), the degree of capital intensity (‘operating leverage’), and the firm size.

Does corporate ownership structure affect its strategy towards diversification

We claim that there is a link between corporate control structure and managers’ strategy towards unrelated mergers and risk diversification. Companies with greater ownership concentration are less diversified. Evidence also shows that corporate diversification generally results in value loss while focussing is value increasing. This highlights the potentially detrimental effect of agency problems on corporate strategy. Copyright

The dominance of intangible assets: consequences for enterprise management and corporate reporting

Intangible assets have become important factors of value creation in today’s knowledge economy. However, individually they are often commodities and only create value in combination with other production factors. Therefore, in order to manage for performance and value, companies and their managers, as well as their investors, need a better understanding of their role as part of the entire value creation system of an organization. The article outlines possible features of an improved management and corporate reporting model. In order to objectively measure the productivity and efficiency of the entire enterprise, the article outlines how total factor productivity can be assessed in organizations as a means to better understand organizational performance.

The Persistence of the Accruals Anomaly

The accruals anomaly - the negative relationship between accounting accruals and subsequent stock returns - has been well documented in the academic and practitioner literatures for almost a decade. To the extent that this anomaly represents market inefficiency, one would expect sophisticated investors to learn about it and arbitrage the anomaly away. Yet, we show that the accruals anomaly still persists and its magnitude has not declined over time. While we find that institutional investors react promptly to accruals information, it is clear that their reaction is rather weak and is primarily characteristic of active investors who constitute a minority of institutions. The main reason: Extreme accruals firms have characteristics which are unattractive to most institutional investors. Individual investors are by and large unable to profit from trading on accruals information due to the high transaction and information costs associated with implementing a consistently profitable accruals strategy. Consequently, the accruals anomaly persists, and will probably endure.

Intangibles and intellectual capital: an introduction to a special issue

The authors believe that intangibles are the major drivers of company growth. In an economy where innovation, information and communication technologies, networks and alliances, as well as the quality of human resources and the way in which they are organized, intangibles will continue to be vital to companies, and the challenge of how to manage, measure and visualize them has to be addressed in theoretical and practical terms. As is well known, intangible assets have a value in use and in some cases also a value in exchange. Beyond their potential informativeness for external stakeholders, intellectual capital (IC) statements seem to have a fundamental function of self-analysis for the firm, forcing it to recognize both its implicit assets and the different links between the various types of capital. The relationship between IC statements and other forms of company reporting, such as social, ethical and environmental reports, should also be explored in depth, to avoid a proliferation of statements which increases the reporting burden on companies and decision-makers.

Sales Stabilization Through Export Diversification

FOLKLORE has it that foreign markets are more risky than domestic markets because of political, economic, and social instability abroad. A normative implication of this belief, sometimes mentioned in the literature, is that a firm must establish itself in the domestic market before venturing into foreign markets; otherwise, it is argued, the inherent instability associated with exports might seriously damage the firms operations. It is shown here that such implications are at variance with the diversification principle in portfolio theory. Specifically, an individual project might be very risky, yet its incorporation with other projects may decrease the overall risk of the portfolio. The overall risk of a group of projects is affected mainly by the relationships among these projects and only slightly by the individual riskiness of each. The hypothesis advanced in this study was that exports, through market diversification, tend to stabilize the firms sales, and the larger the spread of these exports over several markets the more stable the sales. This hypothesis was tested on data selected from a sample of about 500 firms in Denmark, the Netherlands, and Israel. Results of the test were consistent with the hypothesis: sales stability and diversification of exports are indeed positively correlated.

Corporate Earnings: Facts and Fiction

Manipulated earnings played a central role in the slew of corporate scandals which surfaced during the last three years. This article focuses on the vulnerability of earnings to manipulation by managers: it surveys the empirical record of manipulation, their major objectives, and the means of manipulation. It then focuses on the major source of earnings manipulation--the multitude of estimates and subjective judgments underlying the comutation of earnings. The article accordingly concludes with a proposal to curb manipulation by requiring managers to routinely compare key estimates with ex post realizations, and revise earnings in case of large deviations.

Changes in Institutional Ownership and Subsequent Earnings Announcement Abnormal Returns

This study documents an association between changes in institutional ownership during a calendar quarter and abnormal returns at the time of subsequent announcements of quarterly earnings. The result is driven by the portfolio returns of the extreme deciles of changes in institutional ownership, suggesting that institutions trade based on information about future earnings, but that such trading is not widespread. We also find that the difference between earnings announcement returns of the extreme deciles of change in institutional ownership is much greater when change in institutional ownership of a stock is driven by relatively few institutions, measured using the skewness of the distribution of change in institutional ownership of the stock. This result suggests that when fewer differentially informed investors make disproportionately large purchases or sales of stocks, a greater amount of the information on which they base their trades is not impounded in prices until the subsequent earnings announcement. Finally, we show that our results obtain for institutional investors with short-term focus, such as independent advisors, investment companies and insurance companies, but not for institutional investors with long- term focus, such as internally managed pension funds, educational institutions, and private foundations. This result further supports our conclusions regarding informed trading by institutions based on information about forthcoming earnings.
