Coordination in Games with Strategic Complementarities: An Experiment on Fixed vs. Random Matching

In this article, we study behavior in a series of two‐player supply chain game experiments. Each player simultaneously chooses a capacity before demand is realized, and sales are given by the minimum of realized demand and chosen capacities. We focus on the differences in behavior under fixed pairs and random rematching. Intuition suggests that long‐run relations should lead to more profitable outcomes. However, our results go against this intuition. While subjects' capacity choices are better aligned (i.e., closer together) under fixed pairs, average profits are more variable. Moreover, learning is slower under fixed pairs—so much so that over the last five periods, average profits are actually higher under random rematching. The underlying cause for this finding appears to be a “first‐impressions” bias, present only under fixed matching, in which the greater the misalignment in initial choices, the lower are average profits.

企业能力理论体系及其内在逻辑关联

企业能力理论从企业内部探寻决定企业成长的动力,它的发展经历了资源基础观和能力基础观两种流派。能力是基于人力资本能动作用形成的对资源的配置过程,而能力观又包含核心能力和动态能力两个研究分支,其中,核心能力是企业能力概念在组织实践层面上集中于技术和技能关键能力的更深入界定,动态能力则是对核心能力动态发展演化的深入诠释。

Who Lacks Support and Why? An Examination of Mothers' Personal Safety Nets

We use data from the Fragile Families and Child Wellbeing Study (N = 12,140 person-waves) to identify characteristics associated with mothers' having or lacking "personal safety net" support from family and friends. We focus on characteristics that are likely to increase the importance of having support available but may also interfere with the maintenance of supportive ties: poverty, poor physical and mental health, and challenging child rearing responsibilities. By capitalizing on distinctions among these types of personal disadvantages and among types of personal safety nets (financial, housing, child care, and emotional), we help to explain why personal disadvantages are associated with weaker support. Our paper contributes to the literature emphasizing the importance of reciprocity in support relationships and introduces the idea that families that are more difficult to help will have less support available.     

Senior centers in the era of the “Third Age:” Country clubs, community centers, or something else?

This study explored how senior center employees conceptualize their work and organizational mission. Unstructured interviews with multiple service providers (N = 32) and participant observation in one center reveal a growing emphasis on selling individualized lifestyles to young, healthy, and active seniors, as opposed to a more communal, intergenerational approach. In interviews, service providers talked about “community” in vague and ambiguous terms. At the same time, the philosophy of some providers was informed by a well-developed discourse of individual choice. In discussing needed resources and future goals, service providers spoke to the difficulty of appealing to different cohorts of seniors, but focused primarily on the needs of young seniors and expressed a desire to combat the “image problem” of senior centers. These trends have potentially negative implications for intergenerational community and the developmental passages of seniors. Nevertheless, centers offer many opportunities for seniors to forge connections and bridge differences, and the study concludes with some suggestions for building on these existing resources.
