We analyze symmetric pure strategy equilibria in dynamic sponsored search auction games using simulations by restricting the strategies to several in a class introduced by Cary et al. [1]. We show that a particular convergent strategy also exhibits high stability to deviations. On the other hand, a strategy which yields high payoffs to all players is not sustainable in equilibrium play. Additionally, we analyze a repeated game in which each stage is a static complete-information sponsored search game. In this setting, we demonstrate a collusion strategy which yields high payoffs to all players and empirically show it to be sustainable over a range of settings.

Based on visual attention theory of psychology and spatial relations of commodities at real-world stores, this paper has studied influences of three factors to spatial array of commodities at Virtual Reality (VR) stores. These three factors are Flashing (FF), Consistency (CF) and Distance (DF). Findings in this paper indicate that CF shows spatial physical distance, which is in conformity with location-based visual attention; DF shows conceptual distance, which is in conformity with object-based visual attention. Physical distance among commodities has the biggest impact on affecting spatial array of objects, while conceptual distance ranks in the second place.
