Discount dividend-reinvestment and stock-purchase plans allow shareholders to capture part of the underwriting fees incurred in new stock offerings and save sponsoring firms some of the usual underwriting costs. We tested the degree to which individual investors can profitably serve this investment banking function by implementing simple investment/trading strategies designed to capture the discounts and distribute the shares in the market. The large profits earned by our strategies raise serious questions about why it takes firms so long to raise the target level of capital and why many eligible shareholders do not participate in these discount plans.
This paper examines the effects of Broad Tape news releases of earnings and dividend announcements on three aspects of intraday stock price behavior: mean returns, return variance, and serial correlation in consecutive price changes. The initial price reaction is evident in the first pair of price changes following the release (i.e., within a few minutes, at most). The returns earned by simple trading rules dissipate within five to ten minutes, although significant returns are detected in the overnight period and at the opening of trading on the next day. Disturbances in the variance and serial correlation persist for several hours and extend into the following trading day. As a class, dividend announcements induce much less activity than do earnings, although the response to dividend changes is comparable to the earnings announcement effect.
This article examines the tax‐compliance game between taxpayers, a tax‐collecting agency, and third‐party tax‐return preparers. In our model, taxpayers are uncertain about their taxable income and may hire tax practitioners to reduce tax uncertainty. We examine the viability of tax practitioners as a signaling device (taking into account the effects on the behavior of the tax‐collecting agency) and investigate the desirability of encouraging (or discouraging) the use of tax practitioners via the use of alternative tax‐crediting rules. Our study establishes that tax crediting enables legislators to deal better with the consequences of taxpayers' strategic reporting. We show that the effects of changes in crediting rates cannot be replicated by changes in tax rates or penalties; the government would generally like to “price discriminate” in subsidizing tax practitioners' involvement in the tax‐compliance process. It is suboptimal to permit all taxpayers to take a tax credit for preparers' fees; some taxpayers should be denied such a subsidy. Further, if the government is constrained to adopt an identical credit schedule for all taxpayers, it will often find that a policy allowing no tax credit Pareto dominates any uniform crediting policy. Résumé. Les auteurs examinent le jeu auquel se livrent, en matière d'observation de la législation fiscale, les contribuables, les agences de perception de l'impôt et les tiers chargés de la préparation des déclarations de revenus. Dans le modèle retenu par les auteurs, les contribuables sont incertains de leur revenu imposable et peuvent recourir aux services de fiscalistes dans le but de réduire cette incertitude. Les auteurs se penchent sur le caractère indicatif du choix du fiscaliste (en tenant compte de l'influence qu'exerce l'agence de perception sur le comportement) et se demandent s'il convient d'encourager les contribuables à recourir aux fiscalistes ou de les en dissuader au moyen de différents mécanismes de dégrèvement fiscal. L'étude démontre que le dégrèvement fiscal permet au législateur de mieux faire face aux conséquences des stratégies de déclaration des contribuables. L'on constate que la modification des taux d'imposition ou des pénalités ne livre pas les mêmes résultats que la modification des taux de dégrèvement; l'État vise généralement la ≪ discrimination en fonction du prix ≫ en subventionnant le recours aux fiscalistes dans le processus d'observation fiscale. Il ne serait pas optimal de permettre à tous les contribuables de se prévaloir d'un crédit d'impôt pour les honoraires des auteurs de leurs déclarations; une telle subvention devrait être refusée à certains contribuables. En outre, si l'État se voit contraint d'adopter un programme de dégrèvement identique pour tous les contribuables, il constatera dans bien des cas qu'une politique ne permettant aucun dégrèvement est supérieure, au sens de Pareto, à toute politique de dégrèvement uniforme.
ABSTRACT: This study examines firms' behavior with respect to the systematic intraday timing of earnings and dividend announcements. In particular, it tests the hypothesis that good news is more likely to be released when the security markets are open while bad news appears more frequently after the close of trading. Both endogenous (stock price change) and exogenous (comparison to the preceding period's earnings or dividends) classifications are used to distinguish good news from bad, and both forms support the "good news during, bad news after" hypothesis. An information content analysis using daily stock price data is then performed to illustrate how differences in disclosure timing may affect inferences about the magnitude of stock price response, announcement anticipation or news leakage, and the speed of price adjustment.
ABSTRACT: Models that characterize Pareto-efficient sharing of joint venture profits or constrained Pareto-efficient sharing of income in principal-agent contracting problems have ignored tax considerations. We extend the theory by showing that the effect of taxes on optimal contracting (both in the face of and in the absence of moral hazard problems) is related to the effect of changes in risk attitudes towards lotteries over pre-tax income. For example, optimal contracts will reflect the tax-induced demand for insurance of a risk-neutral individual who faces a progressive income tax schedule; that is, the risk-neutral individual will not bear all the risk, and in the face of moral hazard on the act selection of a risk-neutral agent, demand for monitoring will be created where none existed in the absence of the progressive tax. We also show that Pareto-optimal risk-sharing contracts do not generally result in expected tax minimization, even when taxes are modeled as a deadweight loss to the system.
