On the timeliness of tax reform

This paper analyzes efficient government reactions to unanticipated tax avoidance. Quickly reforming tax laws to reduce the effectiveness of new tax avoidance techniques prevents widespread adoption, but indirectly encourages the rapid development of new avoidance methods if prior users are permitted to retain their tax benefits. Tax reforms that immediately prevent new avoidance mean that innovators need not fear imitation by competitors, and cannot rely on copying the innovations of others. Such an activist reform agenda diverts greater resources into tax avoidance activity, and might thereby lead to a faster rate of tax base erosion, than would a less reactive government strategy. Efficient government policy therefore entails either the retroactive elimination of tax savings, with possible associated costs, or else a deliberate pace of tax reform in response to taxpayer innovation.     

Tax avoidance and ex ante cost of capital

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.     

Personal service companies and the public sector

Off-payroll workers in the UK, including personal service companies (PSCs), engaged by the public sector have been giving ‘assurance’ of their tax position to departments in the sector since 2012. Departments must be satisfied with the assurance. For PSCs this requires awareness of complex tax legislation (IR35), which is aimed at preventing tax avoidance. Costs may be incurred in attaining the necessary knowledge. This may bring into question costs incurred in protecting tax revenue. No similar obligation exists in the private sector.     

The effect of tax avoidance crackdown on corporate innovation

To constrain the use of intangible assets in tax-motivated state income shifting, many U.S. state governments adopted addback statutes. Addback statutes reduce the tax benefits that firms can gain from creating intangible assets such as patents. Using a sample of U.S. public firms, we examine the effect of addback statutes on corporate innovation behavior. First, the adoption of addback statutes leads to a 4.77 percentage point decrease in the number of patents and a 5.12 percentage point decrease in the number of patent citations. Second, the “disappearing patents” resulting from addback statutes have significant economic value. Third, after a state adopts an addback statute, a firm with material subsidiaries in that state assigns fewer patents to subsidiaries in zero-tax states, whereas the number of patents assigned to the other states does not change. Overall, our findings suggest that addback statutes impede corporate innovation.     

公司税收规避、税率持续性与股票收益波动率

从税率平稳性角度看,避税活动是否会增加税率波动性进而给企业带来高风险是一个值得探讨的重要问题。从动态视角研究发现,避税是一种策略性行为,低实际税率的企业相比高实际税率的企业,其税率在长时期内能够保持平稳。此外,避税活动并不一定会带来未来税率和股票收益的波动性。这说明公司通常采用持续、稳定的税收策略,不会带来公司风险的激增。进一步研究发现：节税率的波动性与公司未来股票收益波动存在着显著正相关,即当避税引起税率波动较大时,会带来公司股票收益风险的增加。     

How coviewing reduces the effectiveness of TV advertising

In the present study – a naturalistic laboratory experiment – coviewing of TV commercials reduced their effectiveness (delayed proven ad recall) from 63%, obtained by single viewers, to 43%, for both coviewers. During coviewing, the ‘mere presence of another’ apparently distracts each coviewer's attention from the screen. The reduction in TV ads' effectiveness due to coviewing is equivalent to the loss from channel-change zapping, which reduces ad recall to 45%. More deleterious but less prevalent modes of digital video recorder-enabled ad avoidance are skip-button zapping, which reduces recall to 35%, and moderately fast zipping ( × 8 fast forward), which reduces ad effectiveness almost entirely, leaving only 6% recall. This study concludes with some practical suggestions for improving the effectiveness of TV commercials seen by a coviewing audience.     

基于多维频谱地图的干扰规避

针对复杂电磁环境下卫星移动通信系统可靠通信需求,利用频谱地图多维数据呈现优势,提出了基于多维频谱地图的干扰规避方法。通过建立卫星移动通信系统波束、时隙、子频带、干扰强度等多维信息关联的频谱地图,利用数据挖掘方法对频谱可用情况进行预测,基于预测结果及用户QoS(Quality of Service)需求生成干扰规避策略,通过星地联合频谱资源调配实现系统干扰规避。该方法为卫星移动通信系统干扰规避提供了一种全新的思路,可提升卫星移动通信系统干扰防护能力。     

基层商业银行操作风险的防范控制与规避

近年来,由于基层商业银行缺乏管理操作风险的有效组织架构和流程安排,导致操作风险管理职能缺失,由此而引发的损失和金融腐败现象呈上升趋势。为了防范基层商业银行的操作风险。应建立和完善有效的内部控制系统和持续性经营管理机制。强化基层商业银行风险控制的文化建设,从根本上减少操作风险发生的可能性。     

跨国公司转让定价避税与反避税研究

转让定价是跨国公司实施的最主要的转移利润的手法。随着越来越多的跨国公司将在中国设立并发展,对于部分跨国公司通过国际转让定价对我国税基造成的损害,更应该引起重视。从税务当局的角度研究转让定价与反避税问题,成为税收研究和企业管理的一个重要课题。     

Consumers as legitimating agents: How consumer‐citizens challenge marketer legitimacy on social media

Previous research has shown that consumers increasingly challenge the legitimacy of marketers and unsolicited marketing communication in online contexts. Based on a qualitative study, this article examines how and for what reasons consumers challenge marketer legitimacy—the perceived appropriateness of marketers and their activities—in the empirical context of Reddit, a popular social news and community website. The study suggests that consumers challenge or accept marketer legitimacy in online communities based on particular, community and situation specific, legitimacy criteria that reflect and reproduce the values and norms of the community. In doing so, it is argued, consumers play a role as legitimating agents—consumer‐citizens that have the power to confer or deny legitimacy in the context of business‐society relations. Overall, the study advances knowledge in the field of consumer studies in two ways. First, it builds a symbolic interactionist perspective on consumer‐citizens as legitimating agents who enact their active citizenship role in the marketplace by assessing and constructing marketer legitimacy in online communities. Second, it offers an empirically grounded account of how and for what reasons consumer‐citizens challenge or accept the legitimacy of marketers and unsolicited marketing communication in online communities.
