However, prior studies of indirect reciprocity are often limited to a snapshot view of individual interactions in social environments. This paper analyzes indirect reciprocity from a dynamic perspective in the context of a peer-to-peer music sharing network. We have two main findings. First, we reveal that indirect reciprocity is a dynamic social force. An individual's likelihood of contribution changes with the social environment, particularly with others' contribution levels in the network. The individual increases her contribution probability when she observes an increase in the number of contributors while decreases her contribution probability when she observes an increase in the number of free riders. Second, we find that indirect reciprocity is a social norm that is voluntarily enforced by contributors in the network. They do so through the setting of servers to discriminate downloaders. When the number of free riders increases, a contributor is more likely to change the server settings to provide preferential services to other contributors and lesser services to free riders. Our results indicate that indirect reciprocity plays a key role in sustaining private contributions to social networks.","PeriodicalId":343564,"journal":{"name":"Economics of Networks","volume":"24 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132500786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we show that the estimation of consumers' social inter-correlations can be significantly affected by the sampling method used for the study and the topology of the consumers' social network. Specifically, from the estimations results of a spatial model on 14,400 simulated data sets generated with various sampling procedures and network topology, we find that the magnitude of social inter-correlations in consumer networks tend to be underestimated if samples of the networks are taken for conducting the estimations. We further demonstrate that snowball sampling performs better than simple random sampling in estimating the magnitude of social inter-correlations, but the advantage of snowball sampling over simple random sampling reduces in networks characterized with the scale-free power-law distribution for the number of connections of each member. In general, the downward bias in the estimation of social inter-correlations worsens in networks following the scale-free power-law degree distribution when snowball sampling is used. We also discuss the intuitions behind those findings as well as the implications and limitations of them in the paper.","PeriodicalId":343564,"journal":{"name":"Economics of Networks","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126699266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hogan","doi":"10.2139/ssrn.1331029","DOIUrl":"https://doi.org/10.2139/ssrn.1331029","url":null,"abstract":"Social Network Sites (SNS) are a part of everyday social activity for millions around the world (boyd and Ellison, 2007). Sites vary in their affordances, audiences and scope. While some sites cater to specific interest group audiences and 'niche' networks, others, such as Facebook, LinkedIn and MySpace are designed to be general purpose 'social utilities'. Are these sites in fact general purpose social utilities? If so, we should expect to find not only an overlap between the pre-existing personal network and the Facebook network, but also a logic that can connect the two. At present, a host of studies are emerging that take Facebook networks as a stand-in for the 'real' social networks of individuals. The study of community structure through Facebook is meant to signify actual community structure (Traud, Kelsic, Mucha, and Porter, 2008). The study of taste on Facebook is meant to signify actual differences and clusters in taste (Lewis, Kaufman, Gonzalez, Wimmer, and Christakis, 2008). These studies, by virtue of their research design, do not actually measure or examine the personal network. Instead, they capture a slice of Facebook's database and assert that for the group in question (generally college students), it is a reliable proxy for the network of active ties. However, if we are to continue down this road, it is important to connect these networks to the pre-existing studies of personal networks and networking. This enables researchers to leverage past insights on personal networks (such as theories of foci, closure, multiplexity and so forth, c.f., Fischer, 1982) and because it is an important validity check on these online networks. This paper is a research outline and a preliminary quantitative autoanalysis of the relationship between the personal network and one's Facebook network. Insofar as Facebook is the most popular social utility for individuals in the United Kingdom and Canada, it is an ideal candidate to examine how personal networks manifest themselves online (or to the extent that they do so).","PeriodicalId":343564,"journal":{"name":"Economics of Networks","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117291670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Engineering, managing, and leveraging knowledge (individual-, group-, and organizational-level knowledge) are becoming strategic activities in many organizations for achieving competitive advantage.In this context, building organizational capabilities to acquire, create, and disseminate knowledge on a continual basis has become a key challenge for strategy and organizational design experts. While the research and practice in this regard has focused extensively on Information Technology (IT) capabilities for building knowledge communities, the process dimension of learning, knowledge creation, and dissemination has received less attention.This paper articulates the need for cultivating the various learning as well as sociocognitive routines to create and leverage knowledge and suggests how this approach would help formulate better strategies and enhance employees' commitment.This article also highlights the importance of a dynamic approach to managing organizational cognition, a critical factor in organization survival. We further discuss the implications for strategic management and organization development practices.","PeriodicalId":343564,"journal":{"name":"Economics of Networks","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124050549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
