EXTERNALITIES AGGREGATION IN NETWORK GAMES

We generalize the results on the monotonicity of equilibria for network games with incomplete information. We show that not only the distinction between strategic complements and strategic substitutes is important in determining the nature of the Bayesian Nash equilibria, but the nature of the statistic itself is also determinant. We show that understanding the underlying forces behind people's choices may be of fundamental importance for a policymaker that wants to incentivize efficient behavior.     

科研人员的时间分配与生活满意度--性别的视角

在各种职业群体中,专业技术人员工作时间最长,作为其子群体的科研人员工作时间长、压力大是不争的事实,但目前学术界对科研人员时间分配状况与其生活满意度的关系还没有可靠的研究。本研究利用“科技工作者时间利用状况调查”数据,分析我国科研人员时间分配状况与生活满意度的关系,并对其中的性别差异做分析。研究发现,工作时间中科研时间所占的比例与满意度负相关,家务劳动时间过长或过短都负面影响满意度,通勤时间也负面影响满意度,睡眠时间越长满意度越高,休闲娱乐时间长短对满意度的影响不明显;男性科研人员和女性科研人员时间分配与满意度关系模式不同,科研时间占比、通勤时间对男性有影响,家务时间对女性有影响。     

Cognitive Lock‐In Effects on Consumer Purchase Intentions in the Context of B2C Web Sites

The perspective of power law of practice and human capital model asserts that cognitive search costs, cognitive transaction costs, and cognitive switching costs are three lock‐in mechanisms that a business‐to‐consumer (B2C) Web site holds to retain customers. Whether the ability of customer value or the lock‐in mechanism is more dominant for retaining online shoppers has received recent attention, but remains unresolved in the literature. This study sheds light on perceived value and cognitive lock‐in to develop a research model to predict consumer purchase intentions. Empirical results obtained from a survey of customers of a B2C Web site are used to examine the proposed model. Implications of cognitive lock‐in and product cues for increasing purchase intentions are also discussed.

THE IMPACT OF ANTI‐TERRORISM EXPENDITURE ON ECONOMIC GROWTH AND WELFARE

This paper examines the effects of increasing anti‐terrorism expenditure on economic growth rate and social welfare. It is shown that: (i) spending the least amount possible on anti‐terrorism expenditure will lead to a maximum economic growth rate; and (ii) to achieve maximum social welfare, the government should allocate its budget to anti‐terrorism expenditure. The results shed light on why the US government has chosen to uphold and pursue its anti‐terrorism policies in recent years to present day.

Equity swaps in a LIBOR market model

This study extends the BGM (A. Brace, D. Gatarek, & M. Musiela, 1997) interest rate model (the London Interbank Offered Rate [LIBOR] market model) by incorporating the stock price dynamics under the martingale measure. As compared with traditional interest rate models, the extended BGM model is both appropriate for pricing equity swaps and easy to calibrate. The general framework for pricing equity swaps is proposed and applied to the pricing of floating‐for‐equity swaps with either constant or variable notional principals. The calibration procedure and the practical implementation are also discussed. © 2007 Wiley Periodicals, Inc. Jrl Fut Mark 27:893–920, 2007     

Fan-centric social media: The Xiaomi phenomenon in China

In this highly competitive century, social media offers both opportunities and challenges. The concept of social media is top of mind for many entrepreneurs today. Fans are assuming an increasingly active role in co-creating marketing content with companies and their respective brands. Based on the Xiaomi success story in China, we provide a framework for building the power of the fan base and propose a new fan-centric social media business model. We examine the best practice case study of an emerging company's successful efforts to leverage social media in order to reach an important audience of young consumers. Thereafter, we conclude with several lessons related to the integration of social media into a new firm's operation strategy. We strongly recommend that businesses, and especially startups, make good use of powerful social media to develop a business model with fan demand as the core. This is what we call the ‘fan-centric’ social media business model.
