Weak ties and the core discussion network: Why people regularly discuss important matters with unimportant alters

Researchers have paid increasing attention to the core discussion network, the set of friends and family people turn to when discussing important matters. For nearly thirty years, social network researchers have argued that the network is composed of ego's closest or most important alters. This assumption, however, has not been tested empirically. Using original data on an online representative quota survey of 2000 respondents, I find that 45% of the core discussion network is composed of people whom respondents do not consider important to them. In fact, the core discussion network includes doctors, co-workers, spiritual leaders, and other alters whom ego confides in without feeling emotionally attached to. I examine what respondents consider important matters and why they approach weak ties to discuss these. Placing emphasis on the process through which ego mobilizes alters, I develop two theoretical perspectives, which focus on how people identify those appropriate to a topic and how they respond to opportunities in interactional contexts. Findings suggest that ego discusses important matters with non-close alters at times because they are known to be knowledgeable (targeted mobilization) and at times because they are available when important issues arise (opportune mobilization). Results suggest that recent findings about changes in the core discussion network of Americans are consistent with several different possibilities about the nature of strong ties, including those in which there has been no change at all.

基于无限次重复博弈模型的人民币升值节奏问题研究

从游资与预期的角度,利用无限次重复博弈模型研究人民币汇率升值幅度的纳什均衡问题。研究结论包括：纳什均衡汇率与游资不撤离的损失补偿正相关,与中国维持GDP高增长的概率正相关,与贴现系数负相关;在游资大量流进的条件下,人民币汇率升值幅度不仅要包括游资持有者所获得的稳定外汇收益以及损失补偿,还要求汇率调整出现＂超调＂;游资流入对经济的推动扣除风险损失后的剩余,不能小于游资持有者的机会成本加上一定比例升水。
