A group of distinguished finance academics and practitioners discuss a number of topical issues in corporate financial management: Is there such a thing as an optimal, or value‐maximizing, capital structure for a given company? What proportion of a firm's current earnings should be distributed to the firm's shareholders? And under what circumstances should such distributions take the form of stock repurchases rather than dividends? The consensus that emerges is that a company's financing and payout policies should be designed to support its business strategy. For growth companies, the emphasis is on preserving financial flexibility to carry out the business plan, which means heavy reliance on equity financing and limited payouts. But for companies in mature industries with few major investment opportunities, more aggressive use of debt and higher payouts can add value both by reducing taxes and controlling the corporate free cash flow problem. In such cases, both leveraged financing and cash distributions through dividends and stock buybacks signal management's commitment to its shareholders that the firm's excess cash will not be wasted on projects that produce low‐return growth that comes at the expense of profitability. As for the choice between dividends and stock repurchases, dividends provide a stronger commitment to pay out excess cash than open market repurchase programs. Stock buybacks, at least of the open market variety, preserve more flexibility for companies that want to be able to capitalize on unpredictable investment opportunities. But, as with the debt‐equity decision, there is an optimal level of financial flexibility: too little can mean lost investment opportunities, but too much can lead to overinvestment.  相似文献

Pets factor into the daily decision-making of many people. Importantly, various characteristics of these human–animal relationships are known to strongly influence pet owners’ risk behaviour and, consequently, their animals’ welfare during disasters. Yet, few studies have examined a range of such characteristics concurrently in order to describe risk propensity differences in these relationships. In this study, 437 Australian companion-animal (pet) owners reported human–animal relational, personality and attitudinal characteristics, to examine differences in stated tendency to act to secure their pet’s welfare whilst risking potential harm in a hypothetical disaster dilemma. Cluster analysis identified five archetypal profiles differing in relational, personality, attitude and risk-propensity characteristics, as well as in stated willingness to risk personal safety for the well-being of a pet. Results suggest that relational archetypes are an effective means of examining pet–owner risk propensity, to better understand owners’ risk-taking to protect their animals from harm during a disaster.  相似文献

This paper inquires into a recent finding that shows that proximity to the editor of a top accounting journal significantly increases one's chances of publishing in that journal. Three explanations are provided for this finding—two based on ‘rational self-interest’ and one on the ‘good-faith economy’. These explanations are further considered in light of interview data collected from individuals who worked in the same social space as these editors. While the first two of these explanations align themselves with the field's dominant methodological assumptions they alone do not fully describe actual practice in this field. Indeed, to the extent that this field's actors ignore or discount the third, good-faith explanation the field abrogates its scientific commitment to truth-seeking and objectivity, putting its faith instead in a naïve and potentially damaging vision of human behavior.  相似文献

We study the influence of market signals and agency problems on the decision to cancel an announced acquisition. We find major differences between deals involving private vs. public targets. First, controlling for the value of expected synergies, acquisitions are less likely to be cancelled when the target is private rather than public. This finding supports learning rather than the alternative common-information hypothesis. Second, better manager-shareholder interest alignment makes the cancellation of a “bad” deal more likely only when the target is a private firm. This suggests bidder agency problems have a greater influence on acquisition outcome (i.e., learning) when the target is private. Third, cancellation is more likely for private targets when their post-announcement abnormal returns are low, especially if the method of payment includes stock. This indicates that it is important to control for bidder overvaluation when testing the managerial learning hypothesis. Overall, both the learning and agency hypotheses help explain observed differences in deal completion by target type.  相似文献

This paper examines the mutual relationship between broadband penetration, financial development, and economic growth in the 22 Arab League countries for the period between 2001 and 2013. Financial development (represented by broad money supply, claims on the private sector, domestic credit to the private sector, domestic credit provided by the banking sector, market capitalization, turnover ratio, and traded stocks) is assessed both individually, and by a composite index. Our results reveal that there is a long-run equilibrium relationship between broadband penetration, financial development, and economic growth. Additionally, we use a panel vector autoregression model to reveal the nature of Granger causality between the covariates. The most important insight of this study is the presence of bidirectional causality from economic growth to broadband penetration in the long run. In addition, we find that financial development together with broadband penetration Granger-cause economic growth in the long run.  相似文献

Background Lung cancer is the most common type of cancer in the world and is associated with significant mortality. Nivolumab demonstrated statistically significant improvements in progression-free survival (PFS) and overall survival (OS) for patients with advanced squamous non-small cell lung cancer (NSCLC) who were previously treated. The cost-effectiveness of nivolumab has not been assessed in Canada. A contentious component of projecting long-term cost and outcomes in cancer relates to the modeling approach adopted, with the two most common approaches being partitioned survival (PS) and Markov models. The objectives of this analysis were to estimate the cost-utility of nivolumab and to compare the results using these alternative modeling approaches.

Methods Both PS and Markov models were developed using docetaxel and erlotinib as comparators. A three-health state model was used consisting of progression-free, progressed disease, and death. Disease progression and time to progression were estimated by identifying best-fitting survival curves from the clinical trial data for PFS and OS. Expected costs and health outcomes were calculated by combining health-state occupancy with medical resource use and quality-of-life assigned to each of the three health states. The health outcomes included in the model were survival and quality-adjusted-life-years (QALYs).

Results Nivolumab was found to have the highest expected per-patient cost, but also improved per-patient life years (LYs) and QALYs. Nivolumab cost an additional $151,560 and $140,601 per QALY gained compared to docetaxel and erlotinib, respectively, using a PS model approach. The cost-utility estimates using a Markov model were very similar ($152,229 and $141,838, respectively, per QALY gained).

Conclusions Nivolumab was found to involve a trade-off between improved patient survival and QALYs, and increased cost. It was found that the use of a PS or Markov model produced very similar estimates of expected cost, outcomes, and incremental cost-utility.  相似文献

Regulators are often faced with the challenge of both setting efficient prices and avoiding cross subsidy. Successful implementation of these goals requires estimates of both marginal costs and incremental costs. We present a methodology for estimating both marginal and incremental costs for postal products. The proposed algorithms combine micro-unit accounting data and econometric estimation of the cost structure. We apply the methodology to the U.S. Postal Service and produce estimates of marginal and incremental costs for eighteen postal products and incremental costs for another four groups of products.  相似文献

This article explores reasons behind the low take–up of training and redeployment opportunities in a three–year downsizing programme in a National Health Service (NHS) mental health hospital. It examines these from an interpretive paradigm, identifying social–psychological effects on barriers and motivation to training and redeployment. In reporting factors that inhibit the movement of staff from the hospital the findings indicate that the direction of even a well–planned and positively intentioned programme can be confounded by the responses of employees faced with an uncertain future. When drawing up restructuring programmes involving retraining and redeployment, managers need to take into account the anticipated profound reactions of those affected.  相似文献
