We survey 309 sample firms exhibiting behavior consistent with a residual dividend policy and their matched counterparts to learn how they set their dividend policies. The findings reveal that the sample firms are more likely than their counterparts to maintain a long-term dividend payout ratio, use long-run earnings forecasts in setting the dividend, and be unconcerned about the cost of raising external funds. Yet, firms behaving as though they follow a residual dividend policy generally do not profess to follow the policy. At best, the sample firms follow a “modified” residual policy in which they carefully manage their payout ratio and dividend trend. Although it may not be an explicit goal of such a dividend policy, consistently low free cash flow typically results.  相似文献

This paper presents and tests a model of the price dynamics that arise when investors fail to recognize the redundancy of unrealized gains and losses (“UGLs”) that are correlated with the firm’s past returns. Consistent with the predictions of our model, our experiment shows that a firm’s prices and earnings become highly volatile when correlated investment is large and correlated UGLs are made salient by comprehensive income reporting. The results suggest that including correlated UGLs in performance numbers could induce violations of weak-form efficiency that exacerbate volatility in share prices and earnings.  相似文献

We argue that high accruals are likely to be the outcome of rules with an income statement perspective, while low accruals are likely to be the outcome of rules with a balance sheet perspective, and that this has implications for the properties of earnings. Specifically, earnings persistence is affected both by the magnitude and sign of the accruals. Accruals improve the persistence of earnings relative to cash flows in high accrual firms, but reduce earnings persistence in low accrual firms. We show that the low persistence of earnings in low accrual firms is primarily driven by special items. We then show that special item-low accrual firms have higher future stock returns than other low accrual firms. This is consistent with investors misunderstanding the transitory nature of special items. Further analysis reveals that special item-low accrual firms have poor past performance and declines in investor recognition (analyst coverage and institutional holdings). Special items continue to explain future returns after controlling for these factors.  相似文献

Board composition, regulatory regime and voluntary disclosure   总被引:3,自引:0,他引:3  
This study, which examines the association between board monitoring and the level of voluntary disclosure, finds new evidence that firms with a higher proportion of independent directors on the board are associated with higher levels of voluntary disclosure. Although board size and CEO duality are not associated with voluntary disclosure, boards with a majority of independent directors have significantly higher levels of voluntary disclosure than firms with balanced boards. Notably, we find that the presence of an external governance mechanism, the regulatory environment, enhances the strength of the association between the proportion of independent directors and the level of voluntary disclosure. This association is some two to three times greater under a “disclosure-based” regulatory regime than under a “merit-based” regulatory regime.  相似文献

We examine the economic implications arising from a bank using a VaR-constrained mean-variance model for the selection of its trading portfolio as a consequence of the Basle Capital Accord. Surprisingly, we show that when a VaR constraint is imposed, it is plausible that certain banks will end up selecting ‘riskier’ portfolios than they would have chosen in the absence of the constraint. Accordingly, regulators such as the Basle Committee on Banking Supervision should be aware that allowing a bank to use VaR to determine its minimum regulatory capital may increase its fragility. Alternatives to VaR-based bank capital regulation that mitigate or even preclude its perverse implications are presented.  相似文献

This paper uses a case study of BSA to examine corporate governance in a holding company during the interwar years. Recognised as generally progressive in its policy towards financial disclosure, nevertheless BSA attracted hostile criticism from its shareholders, showed little evidence of developing administrative coordination and provided limited detailed information concerning the performance of its subsidiaries. Voice did have an effect in changing the pattern of financial reporting, but even under the pressure of its banker, when financial circumstances deteriorated in the early 1930s, BSA was only prepared to change personnel while organisational structures remained in place.  相似文献

Price bubbles provide a unique opportunity to study the financial acumen of shareholders. We focus on the 1720 South Sea episode as experienced by the Royal African Company whose stock was more speculative than other joint stocks. During 1720 the company had a new large stock issue. This paper examines the financial acumen of those women who traded senior and engrafted stock across 1720. We find that depending on the pricing regime, these women at worst broke even on their activities or had positive speculative gains. Our findings are consistent with a growing literature on the positive link between gender, capital gains and financial markets.  相似文献

On the Merits of Vertical Divestiture   总被引:1,自引:0,他引:1  
This paper demonstrates that vertical divestiture may increase consumer welfare even when the divestiture eliminates substantial scope economies and precludes only limited sabotage. More generally, the merits of vertical divestiture are shown to vary with: (1) the type and the intensity of competition in the retail market; (2) the locus of scope economies under vertical integration; and (3) the relative social values of consumers’ surplus and profit.  相似文献

This study extends research on entrepreneurial behavior by investigating the relationship between the marketing strategy innovativeness (MSI) and new product performance in technology-based new ventures in China. Specifically, premised on contingent resource-based view we argue that MSI is a firm capability that must be bundled with external managerial relationships and be deployed in the appropriate environment to ensure its success. We found that the team's extra industry relationships and market dynamism enhanced the impact of MSI on new product performance. In contrast, top management team's intraindustry relationships, financial relationships, and technology dynamism hindered the impact of MSI on new product performance.  相似文献

While there is increasing evidence that involving suppliers in new product development (NPD) is important, and for many firms even inevitable, there is also evidence that not all such efforts are successful. Firms aiming at implementing this strategy effectively have to pay close attention to several contingency factors on the organizational level and properly manage supplier involvement on the project level. The exploratory case study research underlying this article explores key issues to be considered when involving suppliers in NPD and the counter measures they can take. Our research shows that companies differentiate between so-called “know-how” and “capacity” projects, and that they manage them differently. Furthermore, this research shows that firms outside the automotive and high-tech manufacturing industries are likely to intensify supplier involvement in the future.  相似文献
