We examine how word-of-mouth learning may lead to uniform and possibly inefficient actions in finite time among a network of agents. In our model, agents are identically informed a priori and observe network neighbors’ actions as well as the payoffs of some or all of those actions (a...

Church and King (1993) develops a model of bilingualism, in which they talk about multihoming in language networks. Doganoglu and Wright (2006) talks of multihoming in the presence of price competition. As per the literature available in the public domain, we have not come across any theoretical...

Information can be easily spread through social connections by targeting central individuals in the network. Different standard centrality measures (SCMs) are used to select these central nodes. The SCMs, however, are based on the network topology—shaped only by the number of connections—...

The development of stochastic models for the analysis of social networks is an important growth area in contemporary statistics. The last few decades have witnessed the rapid development of a variety of statistical models capable of representing the global structure of an observed network in...

Social networking sites make it easier for people to form, maintain, and identify relationships. Yet, building social capital also involves strengthening weaker ties. Can social networking sites help people strengthen pre-existing ties with others? In this paper, we theorize and test two...

This paper estimates a dynamic model of user behavior in a social network site using unique data on the daily login activity of a sample of members of MySpace.com. We view a social network as a stock of capital that yields a flow of utilities over time by creating interactions between the site...

As a common practice, various firms initially make information and access to their products/services scarce within a social network; identifying influential players that facilitate information dissemination emerges as a pivotal step for their success. In this paper, we tackle this problem using...

Social networks are not only a tool for communication. It is turned into a socio-political asset in the struggle for the specific interests of a group of people who can acquire and/or manage this asset. In the paper we use data of communities of the Russian-Ukrainian segment of the social...
