SOCIAL CHOICE FROM AN n‐DIMENSIONAL EUCLIDEAN SPACE: A SHORT IMPOSSIBILITY PROOF

Most presentations of social choice theory are difficult for a non‐specialist to follow. This paper attempts to provide some feel for what is going on by providing a short proof of an impossibility theorem in terms of the techniques that are familiar to political‐economists. We illustrate the advantages of this approach with a short proof of an impossibility theorem.     

Blockholder Trading,Market Efficiency,and Managerial Myopia

This paper analyzes how blockholders can exert governance even if they cannot intervene in a firm's operations. Blockholders have strong incentives to monitor the firm's fundamental value because they can sell their stakes upon negative information. By trading on private information (following the “Wall Street Rule”), they cause prices to reflect fundamental value rather than current earnings. This in turn encourages managers to invest for long‐run growth rather than short‐term profits. Contrary to the view that the U.S.'s liquid markets and transient shareholders exacerbate myopia, I show that they can encourage investment by impounding its effects into prices.     

Diversification and top management team complementarity: is performance improved by merging similar or dissimilar teams?

This study examines the impact of complementary top management teams (defined as differences in functional backgrounds between the acquiring and acquired firm managers) on post-acquisition performance. Based on a sample of 147 acquisitions completed during 1986–88, we find that complementary backgrounds have a positive impact on postacquisition performance in both related and unrelated acquisitions. Another major finding is that complementarity is negatively related to top management team turnover among acquired managers, suggesting that differences in functional backgrounds are more easily integrated into the new organization. Finally, top management team turnover among acquired managers is negatively related to postacquisition performance. These findings highlight the importance of examining complementarity in terms of differences, and reinforce the notion that differences have the potential to create unique value for the organization. © 1997 by John Wiley & Sons, Ltd.     

Asymmetry in Stock Returns Following Block Trades on the Australian Stock Exchange: A Note

A number of recent US. studies have examined the price impact of large (block) trades using intraday data. A major finding is that the price movement following block trades continues upwards following purchases but reverses following sales. This asymmetry in price behaviour, which suggests that block sellers pay a liquidity premium while block buyers do not, has been described as 'intriguing' and a 'key puzzle'. The purpose of this note is to determine whether the phenomenon exists on the Australian Stock Exchange. Evidence consistent with the 'puzzling' asymmetry is shown to exist when returns are measured from the block trade until the close of trade. Contrary to US. findings, which have shown that prices appear to reverse following both block purchases and sales in transaction time analysis, the asymmetry in price behaviour is also demonstrated to exist in transaction returns for the ASX. All results are found to be robust to a number of research design innovations and data partitions.     

How Big is the Tax Advantage to Debt?

This paper uses an option valuation model of the firm to answer the question, “What magnitude tax advantage to debt is consistent with the range of observed corporate debt ratios?” We incorporate into the model differential personal tax rates on capital gains and ordinary income. We conclude that variations in the magnitude of bankruptcy costs across firms can not by itself account for the simultaneous existence of levered and unlevered firms. When it is possible for the value of the underlying assets to jump discretely to zero, differences across firms in the probability of this jump can account for the simultaneous existence of levered and unlevered firms. Moreover, if the tax advantage to debt is small, the annual rate of return advantage offered by optimal leverage may be so small as to make the firm indifferent about debt policy over a wide range of debt-to-firm value ratios.     

Stock Return Predictability and The Role of Monetary Policy

This article examines whether shifts in the stance of monetary policy can account for the observed predictability in excess stock returns. Using long-horizon regressions and short-horizon vector autoregressions, the article concludes that monetary policy variables are significant predictors of future returns, although they cannot fully account for observed stock return predictability. I undertake variance decompositions to investigate how monetary policy affects the individual components of excess returns (risk-free discount rates, risk premia, or cash flows).     

On interim information and the information content of firm earnings: A state variable approach*

Abstract. This paper uses a state variable characterization of firm earnings to develop an economic model of interim information and its effects on the information role of announced earnings. The model provides a simple yet rigorous approach for assessing, both theoretically and empirically, the potential effects of interim information about non firm-specific state variables on the information role of announced earnings. It is shown that, under appropriate conditions, uncertainty about firm earnings can be decomposed into uncertainty about firm-specific and non firm-specific state variables. This decomposition provides economic structure to the meaning of interim information. It is demonstrated, both in the theoretical and empirical analyses, that the interim revelation of industry-wide state variables diminishes the information role of announced earnings. Résumé. L'auteur utilise une variable caractérisant la situation de l'entreprise au chapitre des bénéfices (variables d'état), en vue d'élaborer un modèle économique de l'information périodique et de ses conséquences sur le rôle informatif des bénéfices déclarés. Le modèle, simple mais rigoureux, permet d'évaluer, en théorie aussi bien qu'en pratique, les conséquences que peut avoir l'information périodique relative aux variables d'état qui ne sont pas spécifiques à l'entreprise (mais spécifiques au secteur) sur le rôle informatif des bénéfices déclarés. Il est démontré que, dans des circonstances appropriées, l'incertitude relative aux bénéfices de l'entreprise peut être décomposée en incertitude relative aux variables d'état spécifiques à l'entreprise et non spécifiques à l'entreprise. Cette décomposition donne une structure économique au sens de l'information périodique. Les études tant théoriques qu'empiriques démontrent que la communication périodique des variables d'état de tout un secteur diminue le rôle informatif des bénéfices déclarés.     

Retained ownership and the valuation of initial public offerings: Canadian evidence*

Abstract. Recent empirical work by Krinsky and Rotenberg (KR) (1989a, b) suggests that the relationship between entrepreneurial ownership retention and initial valuation of unseasoned common shares may not hold in the Canadian environment. In this study, we replicate and extend KR's tests on our more recent Canadian sample of 180 IPOs that listed on the TSE between 1984 and 1987. We find empirical evidence that initial valuation is increasing in the ownership retention signal (α), even when retention is included with various other possible managerial or firm-specific signals about future cash flows. Further, we find this result to be robust with respect to a number of different model specifications as well as across different definitions of who the entrepreneur is, different classes of common stock, and different types of offering units. Résumé. Les récents travaux empiriques de Krinsky et Rotenberg (1989a, b) donnent à penser que la relation entre la rétention par l'entrepreneur d'une participation dans l'entreprise et l'évaluation initiale d'actions ordinaires émises par une entreprise non solidement établie pourrait ne pas tenir dans le contexte canadien. Dans l'étude qui suit, les auteurs reprennent, en les élargissant, les tests de Krinsky et Rotenberg auprès d'un échantillon canadien plus récent de 180 premiers appels publics à l'épargne sur la bourse de Toronto, entre 1984 et 1987. Ils démontrent empiriquement que l'évaluation initiale des actions émises augmente au signal de rétention d'une participation (α), même lorsque la rétention fait partie de divers signaux possibles relatifs à la direction ou spécifiques à l'entreprise au sujet des flux monétaires éventuels. Les auteurs concluent en outre que la solidité de cette conclusion résiste à la modification des caractéristiques du modèle ainsi qu'à la modification des définitions de l'identité des entrepreneurs, des différentes catêgories d'actions ordinaires et des différents types d'unités émises.     

The voluntary inclusion of earnings forecasts in IPO prospectuses*

Abstract. This study examines empirically the role played by direct disclosure in the valuation of initial public offerings (IPOs). We investigate why some firms making an initial public offering in Canada include an earnings forecast in the offering prospectus and others do not, and, in particular, the role of such direct disclosures in IPO valuation. We explore several hypotheses motivated by the voluntary disclosure and signaling literatures. Our results are consistent with the hypotheses that (1) forecasters have “good news” to reveal about future earnings prospects relative to nonforecasters, (2) the earnings forecast signals are valuation relevant, and (3) the market is able to correct for expected forecast error or bias in the earnings forecast. Résumé. Les auteurs font une analyse empirique du rôle que joue la présentation directe d'information dans l'évaluation des premiers appels publics à lépargne. Ils se penchent sur les raisons pour lesquelles certaines sociétés qui font appel public à l'épargne au Canada intègrent à leur prospectus d'émission des prévisions de bénéfices, alors que d'autres ne le font pas, et ils s'intéressent en particulier au rôle de la présentation directe de ce genre d'information dans l'évaluation d'un premier appel public à l'épargne. Ils examinent plusieurs hypothèses inspirées d'ouvrages traitant de présentation volontaire d'information et d'indicateurs. Les résultats obtenus sont conformes aux hypothèses selon lesquelles 1) ceux qui font état de prévisions ont de l'information positive à communiquer au sujet des perspectives de bénéfices, contrairement à ceux qui ne font état d'aucune prévision, 2) les indicateurs que représentent les prévisions de bénéfices sont pertinents à l'évaluation et 3) le marché a la capacité de corriger l'information qu'il reçoit pour tenir compte des erreurs ou des distorsions anticipées dans les prévisions de bénéfices.
