Optimal Digital Rights Management with Uncertain Piracy

Many firms that sell digital copies of copyrighted materials online face a common dilemma: the use of digital rights management (DRM) to impede pirates can impose restrictions on legitimate use. We introduce a two‐period model in which the use of DRM in the first period affects the probability that a consumer finds a pirated copy in the second period; the threat of legal action reduces consumers’ consumption of pirated copies; and firms choose whether to sell, and at what prices, either strongly or weakly DRM‐protected products, or both. Furthermore, we incorporate the role of uncertainty concerning future levels of piracy. Using a two‐period model with uncertainty, we investigate a firm's optimal DRM strategies and present the optimal pricing strategy as well as product launch strategy under different market conditions. We find that one important characteristic of the optimal strategy is that it is optimal to maintain the same product line configuration strategy for both periods. We also characterize the conditions under which each strategy is optimal.

The Impact of Personal Finance Education Delivered in High School and College Courses

This study investigates the impact of personal finance education delivered in high school and college. Outcomes of interest were investment knowledge and household savings rates measured years after the financial education was delivered. A web-based survey with questions about participation in financial education, financial experiences, income and inheritances, and demographic characteristics was administered to 1,039 alumni from a large midwestern university. Participation in a college level personal finance course was associated with higher levels of investment knowledge. Experience with financial instruments appeared to explain more of the variance in both investment knowledge and savings rates. No significant relationship between taking a high school course and investment knowledge was found. Financial experiences were found to be positively associated with savings rates.

The potential of online social networking data for augmenting the study of high-risk personal networks among young men who have sex with men at-risk for HIV

Capturing dynamics in high-risk personal networks is essential for preventing HIV transmission. Online social networking data offer incentive to augment traditional selfreported approaches for network enumeration. To explore what online networks reveal about dynamics among high-risk associates, we examine the relationship between egocentric confidant and sex networks and personal Facebook friendship networks of a cohort of young Black men who have sex with men. Although overlap exists between self-reported and Facebook associates, the stabilities of each were unrelated. Confidants who were also Facebook friends with a respondent were, however, more likely to be retained. Thus, Facebook networks contain stable confidants.

分红型寿险产品保单红利所得税税制研究

目前,对分红险的保单红利是否应该征收个人所得税;在保险业界和税务部门以及学术界都存在争议。文章在借鉴国外分红脸保单红利个人所得税税制的基础上,结合我国分红脸的发展特点,提出应该适时建立分红险保单红利所得税税制。该税制的设计应遵循公平和效率原则,采用税延型的代扣代缴方式予以征税,征税范围应为超出保险成本部分、利差部分以及保单红利的生息部分。最后文章从税务机关的主张和文章的建议税制两个方面对开征保单红利所得税对寿险业的影响进行了比较分析,得出了文章的建议税制在保单持有人的保单收益和税务机关的征税总额方面优势明显的结论。

数字化的哲学局限与美学悖论

对数字化技术的价值探析，需要有人文理性的意义维度，以廓清其与人类预设的文化命意和精神旨趣相协同的可能限度，即数字化技术方式背后的哲学局限与艺术美学悖论。前者表现为数字标准化对事物个性意义体认的限制，数字平面化对事物深度认知复杂性的限制和数字的知识化对意志自由的限制；后者则蕴含了数字虚拟与艺术真实、文学在线与文学性消散、个体中心与主体边缘、精神临场与身体缺席等方面的对立与统一。
