社交云中的资源可用性：经济学视角
Resource Availability in the Social Cloud: An Economics Perspective
摘要：
本文重点研究了社会云的形成，其中代理人参与了一个基于封闭性的条件资源共享，并建立自己的资源共享网络。本文件的目标是：（1）研究了Agent的链接添加和删除决策对其局部和全局资源可用性的影响，（2）分析了溢出效应，即一对Agent之间的链接添加对其他Agent效用的影响，（3）研究了Agent的亲密度在确定这些Agent在网络中经历何种类型的溢出效应中的作用，以及（4）对代理的选择进行建模，所述代理建议他们想要在社交云中与谁添加链接。调查结果包括以下内容。首先，代理的链接添加（删除）的决定增加（减少）他们的本地资源的可用性。然而，这些意见并不适用于全球资源供应情况。其次，在连通网络中，代理人会经历正溢出效应或负溢出效应，不存在没有溢出效应的情况。当且仅当网络是断开连接的，并且由两个以上的组件（子网络）组成时，代理人没有观察到溢出效应。此外，如果由于新添加的链接而导致代理（不参与链接添加）的接近度没有变化，则代理会经历负溢出效应。虽然为了获得积极的溢出效应，必须增加代理人之间的密切程度，但这一条件并不充分。通过关注参数，如接近度和最短距离，我们提供的条件下，代理选择添加链接，以最大限度地提高其资源的可用性。
英文摘要：
This paper focuses on social cloud formation, where agents are involved in a closeness-based conditional resource sharing and build their resource sharing network themselves. The objectives of this paper are: (1) to investigate the impact of agents' decisions of link addition and deletion on their local and global resource availability, (2) to analyze spillover effects in terms of the impact of link addition between a pair of agents on others' utility, (3) to study the role of agents' closeness in determining what type of spillover effects these agents experience in the network, and (4) to model the choices of agents that suggest with whom they want to add links in the social cloud. The findings include the following. Firstly, agents' decision of link addition (deletion) increases (decreases) their local resource availability. However, these observations do not hold in the case of global resource availability. Secondly, in a connected network, agents experience either positive or negative spillover effect and there is no case with no spillover effects. Agents observe no spillover effects if and only if the network is disconnected and consists of more than two components (sub-networks). Furthermore, if there is no change in the closeness of an agent (not involved in link addition) due to a newly added link, then the agent experiences negative spillover effect. Although an increase in the closeness of agents is necessary in order to experience positive spillover effects, the condition is not sufficient. By focusing on parameters such as closeness and shortest distances, we provide conditions under which agents choose to add links so as to maximise their resource availability.
