First Experiences with a Ranking Method for Portfolio Selection in Applied Research

Abstract— Starting from the premise that commercial research aims to maximize the expected profitability for a given expenditure on research, a Profitability Index is derived based on a decision tree concept. The practical application of this Profitability Index at the British Petroleum Company Limited's Sunbury Research Centre in the context of research sponsored by several departments is then described.     

Disclosure and Recognition Requirements: Corporate Investment Decisions with Externalities*

This paper examines the effects of disclosure and recognition requirements on investment decisions when shareholders have limited liability. Firms' investment projects have either high initial pollution prevention costs or high subsequent clean‐up costs, and their liability for clean‐up costs may be either individual or joint and several. Even with individual liability for clean‐up costs, shareholders' limited liability creates an incentive to select the latter project type and to impose costs on the rest of the economy. This tendency is exacerbated when clean‐up liability is joint and several. We show that a disclosure requirement cannot have an unambiguous effect on the selection of the “cleaner” project. However, an accrual requirement, together with an accounting‐based dividend restriction, is shown to promote choice of the project that imposes lower expected costs on the rest of the economy. Moreover, we find that it is possible for a recognition requirement to have a greater impact in a joint‐and‐several liability regime than in an individual liability regime.     

Why Do Large Firms' Prices Anticipate Earnings Earlier than Small Firms' Prices?*

This paper presents evidence that the positive association between firm size and price leads of earnings is not solely a function of private search incentives for firm‐specific information. Specifically, we find that small‐firm prices also lag large‐firm prices with respect to industry‐wide information. Our empirical analysis extends Collins, Kothari, and Rayburn 1987 and Freeman 1987, who document that security‐price leads of earnings are positively associated with market capitalization. In particular, we examine the association between firm size and the timing of security returns for two components of annual earnings changes: the average change for a firm's industry and the firm's idiosyncratic change. We find that large firms' prices have a longer lead than small firms' prices with respect to both components. Large firms' early lead on industry‐wide earnings suggests that returns of large firms predict returns of same‐industry small firms. To test this implication, we construct a portfolio of long (short) positions in small firms when the prior month's returns of large firms in their industry are above (below) average for large firms in other industries. This zero investment portfolio earns 4.5 percent over 12 months.     

Promoting i‐Safety: Effects of Privacy Warnings and Privacy Seals on Risk Assessment and Online Privacy Behavior

Using social cognitive theory, this study experimentally examines the effects of explicit privacy warnings, a clear, conspicuous, and concise presentation of the benefits and risks associated with database information practices stated in a Web site’s privacy policy. Warnings increased perceptions of the risks associated with information practices and decreased disclosures, but not in the presence of a privacy seal. The effects were also moderated by consumer privacy self‐efficacy and involvement with privacy. The results support the development of privacy warnings as a part of consumer privacy self‐regulatory efforts and the use of a social cognitive paradigm for understanding consumer privacy behaviors.     

The Impact of Non-Serial Publications on Research in Accounting and Finance

This study examines the role of books and official Publications in accounting and finance research. From an analysis of thirteen leading journals for the year 1987–8 we report on the characteristics of such non-serial materials used by authors to support their research. We find that the accounting discipline in particular has become more open to influence from other disciplines. The individual perspectives of these thirteen journals can be partially revealed by their use of non-serial materials. Using cluster analysis we examine inter-journal variations in the disciplinary pattern of book citations and the distribution of citations to official bodies. Several relatively homogeneous groupings are identified.     

Primes and Scores: An Essay on Market Imperfections

This paper investigates the reported relative mispricing of primes and scores to the underlying stock. Given transaction costs, we establish arbitrage-based bounds on prime and score prices. We then develop a new nonparametric statistical technique to test whether prime and score prices violate these bounds. We find that prime and score prices do exceed stock prices, and often by a considerable amount. We demonstrate that this increased value is most likely due to the score's ability to save on the costs of dynamic hedging. We also show how short sale and trust size constraints impede the ability to arbitrage price disparities.
