Internet market strategies: Antecedents and implications

The Web is a new market channel that has become a serious alternative to traditional channels. At present, there is little strategy analysis available to guide a company's decision about its involvement in the internet market. In this paper, we differentiate between the internet and traditional market channels and define two fundamental strategies for operating on the internet as: pure and mixed. Based on models of competition in microeconomic theory and resource-based perspectives, we develop a conceptual model for channel selection. We discuss the results and their implications for companies operating on the internet.     

回归理性、充满希望的2002年宽带市场

2002年中国宽带接入市场呈现出相对理性的高速发展态势,跟踪研究表明,宽带接入业务具有如下特征:①整体发展环境有利,业务发展仍面临挑战;②市场趋于理性,竞争格局变化;③市场总量仍小,发展保持高速;④业务收入仍低,ARPU下降过快;⑤市场策略单一,业务整合不够;⑥市场仍需培育,前景依然光明。随着宽带接入业务泡沫的逐步缩减,盈利模式的成熟,价值链的重构,这项“问题”类业务,有望成为新的“明星”。     

基于理性指标的马尔可夫链股市态势预测方法

由于股票市场存在人为扰动性,使得基于情绪的股市预测算法效果不佳。针对股市的诱多诱空问题,提出一种基于理性指标的马尔可夫链股市态势预测算法（RI_MCA）。提取股市的主要理性特征,并对这些理性特征进行量化;通过主成分分析将这些理性特征融合成理性指标,并利用理性指标获取股市的买卖点;将买卖点所对应的股市状态引入到马尔可夫链中,实现股市态势预测。在理性指标和股市状态相背离情况下会降低买卖点的可靠性,因而通过将特征背离引入到RI_MCA算法中提出了RICD_MCA算法,RICD_MCA算法根据特征背离程度对RI_MCA算法的结果进行调整优化。在上证指数上的实验比较与分析结果表明,RICD_MCA算法具有更高的预测精度。

Self-control,organizational context,and rational choice in Internet abuses at work

Cyber criminals use the Internet as a major platform to launch malware and social engineering attacks. Employees’ violation of Internet use policy (IUP) elevates a firm’s security risks from cyber-attacks. In the literature, such deviant behavior is generally considered to be the result of a cost-benefit calculus. However, this study shows that dispositional factors such as self-control and procedural justice moderate the cost-benefit calculus. We conclude that self-control and procedural justice need to be integrated with the Rational Choice Theory to better explain Internet abuses at work.     

Synthesis with rational environments

Synthesis is the automated construction of a system from its specification. The system has to satisfy its specification in all possible environments. The environment often consists of agents that have objectives of their own. Thus, it makes sense to soften the universal quantification on the behavior of the environment and take the objectives of its underlying agents into an account. Fisman et al. introduced rational synthesis: the problem of synthesis in the context of rational agents. The input to the problem consists of temporal logic formulas specifying the objectives of the system and the agents that constitute the environment, and a solution concept (e.g., Nash equilibrium). The output is a profile of strategies, for the system and the agents, such that the objective of the system is satisfied in the computation that is the outcome of the strategies, and the profile is stable according to the solution concept; that is, the agents that constitute the environment have no incentive to deviate from the strategies suggested to them. In this paper we continue to study rational synthesis. First, we suggest an alternative definition to rational synthesis, in which the agents are rational but not cooperative. We call such problem strong rational synthesis. In the strong rational synthesis setting, one cannot assume that the agents that constitute the environment take into account the strategies suggested to them. Accordingly, the output is a strategy for the system only, and the objective of the system has to be satisfied in all the compositions that are the outcome of a stable profile in which the system follows this strategy. We show that strong rational synthesis is 2ExpTime-complete, thus it is not more complex than traditional synthesis or rational synthesis. Second, we study a richer specification formalism, where the objectives of the system and the agents are not Boolean but quantitative. In this setting, the objective of the system and the agents is to maximize their outcome. The quantitative setting significantly extends the scope of rational synthesis, making the game-theoretic approach much more relevant. Finally, we enrich the setting to one that allows coalitions of agents that constitute the system or the environment.
