This study examines the association between tax avoidance and ex ante cost of equity capital. Based on prior research, we develop two proxies for investors’ expectations of tax avoidance and explore whether deviations from those expectations result in higher ex ante cost of equity capital. We find that the ex ante cost of equity capital increases with tax avoidance that is either below or above investor expectations and that the increase is larger for tax avoidance that exceeds investors’ expectations. We then examine whether firms that alter their future tax avoidance exhibit a lowering of their ex ante cost of equity capital and find that tax avoidance decreases (increases) from the prior year for firms that were above (below) investors’ expectations in the prior year. These results are consistent with the trade‐off suggested by the Scholes and Wolfson framework and reinforce the notion that balancing tax benefits and non‐tax costs is an important feature of firms’ tax planning.  相似文献

Honey is one of the important non-timber forest products consumed in the Democratic Republic of Congo (DRC) and, as such, an important source of income for many households. However, poor knowledge of buyers’ preferences in the marketing of honey presents a major challenge to the profitability of the honey enterprises. The research presented in this article identifies key consumer characteristics that influence the preferences of honey consumers in the DRC. The primary data source used in this analysis is drawn from a survey of 214 consumers. Results show that consumers who are married and have reached at least the level of secondary education have a strong preference for local forest and savannah honey. Those between the ages of 30 and 50 do not prefer honey from beekeeping, but would rather have it imported. We conclude that segmentation of the honey market and increasing consumer awareness must go in tandem in order to develop a good marketing strategy.  相似文献

After more than 50 years of self‐regulation of the US auditing profession, the Sarbanes‐Oxley Act of 2002 (SOX) created the Public Company Accounting Oversight Board (PCAOB) as a quasi‐governmental entity with statutory authority to inspect accounting firms that audit public clients. The frequency of this inspection is annual or triennial, based upon the number of public clients the firm audits. We examine the effects of these two levels of inspection frequency on financial reporting quality and audit fees for clients of small and midsize public accounting firms. Our findings provide evidence of significantly higher audit quality and audit fees for clients of annually inspected firms relative to clients of triennially inspected firms. These findings are robust to auditor‐client alignment analyses, propensity score matching, time‐series analyses, examination of firms that have changed from triennial to annual inspection, and particular examination of firms with inspection deficiencies. Overall, our study suggests that the two‐tier frequency system of PCAOB inspection may have also resulted in two‐tier audit quality and audit fee systems for small and midsize public accounting firms, with more frequent inspection leading to more rigorous and informed auditor decisions. We discuss the implications of our results for the Board and the profession at large.  相似文献

Brand pages in social media are a great way to foster consumer gathering around a brand, but it can be challenging to keep fans engaged and coming back to see updated content. Brands with millions of fans on Facebook have seen organic reach fall below 2% of their base. In this article, we describe how the creation of virtual brand communities can help brand managers increase fan engagement. We suggest the steps, conditions, advantages, and limitations involved in nurturing a brand page as an online social gathering that assumes some of the characteristics of a virtual brand community. The results of our study show that a brand page can have some of the characteristics of a virtual brand community—topical information exchange, identity communication, and establishment and internalization of cultural norms. We also show the importance of having celebrities among fans in order to foster social interactions and legitimate social practices on brand pages.  相似文献

Establishing, maintaining, and enhancing relationships over the Internet have progressively gained global attention. Nevertheless, the dawn of this modernization draws many theoretical debates and practical concerns, some of which have received little research attention, especially within the Sub-Saharan region of Africa. On this premise, we explored the contemporary practice, challenges, and benefits of Internet-based relationship marketing (RM) within the Ghanaian telecommunication industry. Expert interviews with 12 employees from four telecommunication firms elicited a wealth of experiential data analyzed thematically to understand the practice, challenges, and emerging benefits of Internet-based RM. Our findings suggest that issues of privacy concerns, erosion of face-to-face communication, and the tendency of unsolicited communication do not necessarily militate Internet-based RM within the Ghanaian telecommunication industry. We also identified emerging benefits, including online “virality,” a discovery environment, and improved firm reputation. We suggest enhancing online personalization through empathy, creating value with analytic information and managerial openness, and supporting enhanced knowledge development within the area. Directions for future studies include the possibility of comparative studies across service industries and examining the role of content marketing in Internet-based relationships. The challenge of exploring Internet-based RM was similar to hitting a moving target, as the use of the Internet for relationship marketing activities is constantly evolving. Additionally, our findings and conclusion are confined to the knowledge contribution of the experts interviewed. As one of the few studies within the Sub-Saharan region, we expand contributions from the Sub-Saharan domain. The findings of this study also bring to light new insights for establishing, maintaining, and enhancing Internet-based relationships.  相似文献

Calculating the probability of the corresponding significance point is important for finite sample sizes. However, it is difficult to evaluate this probability when the sample sizes are moderate to large. Under these circumstances, consideration of a more accurate approximation for the distribution function is extremely important. Herein, we performed a saddlepoint approximation in the upper tails for the distribution of the sum of independent non‐identically uniform random variables under finite sample sizes. Saddlepoint approximation results were compared with those for a normal approximation. Additionally, the order of errors of the saddlepoint approximation was derived. © 2014 The Authors.

The apparent success of state‐managed market economies has challenged the conventional wisdom that liberal democracy is the norm around which all capitalist countries tend to converge. If the link between democracy and development is more tenuous than we often think, the authoritarian variety of capitalism is not without its own problems, especially with respect to political legitimacy, innovation and regional development. This article explores these issues through the prism of ‘authoritarian modernization’ in Russia. We argue that this strategy is unlikely to succeed, even in its own terms, because (1) the political system fails to create favourable institutional conditions for modernization; (2) the economic system is beset by deeply embedded structural problems; and (3) the regional policy apparatus is torn between the goals of spatial equalization and spatial agglomeration. The article focuses on the Skolkovo Innovation Centre, the main symbol of Russian modernization, to demonstrate the territorial repertoire of the mega‐project, a state‐sponsored development strategy to create innovation clusters from above because they cannot emerge from below.  相似文献

Extreme value theory is concerned with the study of the asymptotic distribution of extreme events, that is to say events which are rare in frequency and huge in magnitude with respect to the majority of observations. Statistical methods derived from it have been employed increasingly in finance, especially for risk measurement. This paper surveys some of those main applications, namely for testing different distributional assumptions for the data, for Value‐at‐Risk and Expected Shortfall calculations, for asset allocation under safety‐first type constraints, and for the study of contagion and dependence across markets under conditions of stress.  相似文献

To gain a better understanding of online brand communities, this study has examined why people joined in online brand communities and whether there were some differences in the motivations of Internet users based on different cultures. Open-ended questions were asked to the community members from both South Korean Automobile Online Brand Communities (KAOBC) and American Automobile Online Brand Communities (AAOBC) in the first stage and then generated and utilized an online survey for the study. The study found that KAOBC members tended to have a stronger social network, business, and communication motivations than AAOBC members. As a primary motivation, information seeking is the strongest motivation for members of both KAOBC and AAOBC. They had a similar level of information motivation.  相似文献

Using tools from spectral analysis, singular and regular perturbation theory, we develop a systematic method for analytically computing the approximate price of a large class of derivative‐assets. The payoff of the derivative‐assets may be path‐dependent. In addition, the process underlying the derivatives may exhibit killing (i.e., jump to default) as well as combined local/nonlocal stochastic volatility. The nonlocal component of volatility may be multiscale, in the sense that it may be driven by one fast‐varying and one slow‐varying factor. The flexibility of our modeling framework is contrasted by the simplicity of our method. We reduce the derivative pricing problem to that of solving a single eigenvalue equation. Once the eigenvalue equation is solved, the approximate price of a derivative can be calculated formulaically. To illustrate our method, we calculate the approximate price of three derivative‐assets: a vanilla option on a defaultable stock, a path‐dependent option on a nondefaultable stock, and a bond in a short‐rate model.  相似文献
