Burt and Coleman Networks in Electronic Intermediation

Two predominant network forms, Burt and Coleman, are delineated to identify the underlying structure and dynamics of electronic intermediation models. Basic differentiating characteristics between the two network types, including nodes, structures, products, transactions, market maturity, and technology improvement, are identified. Two comparative cases are analyzed to illustrate the utility of the constructs. The analysis shows that while both Burt and Coleman networks are viable strategies for electronic intermediation, Burt rents are easier to obtain and difficult to maintain, whereas Coleman rents are more difficult to obtain, but easier to defend. Accordingly, we find a tendency for intermediaries in Burt networks to attempt to affect Coleman rents as a long-term strategy

Internet sales as a new mode of internationalization

The way that organizations explore the Internet has been the focus of a substantial body of scientific studies and non-academic reflection. The main goal of this study is to analyze the potential of the internet as a mode of internationalization and the factors that influence the results of the adoption of this mean to access foreign markets. For this purpose, we examine the determinants of the level of international sales made via internet estimating an ordered probit model. The results show that the importance of previous experience in using the internet and developing international activity, together with the level of internet marketing budget , the level of investment on internet sophistication, the firm dimension, the business age and the type pf activity are variables that determine the results obtain in the international sales trough the internet.info:eu-repo/semantics/publishedVersio

Peer-to-Peer Lending: An Empirical Study

Online peer-to-peer (P2P) lending, where individual investors provide unsecured loans directly to individual borrowers without the intermediation of banks, has experienced rapid growth in recent years. One of its defining features is the presence of social networks, which could provide important credit information about borrowers. Drawing on the literature in finance and social networks, I study whether and how network metrics affect the outcome of financial transaction in this market, and whether such credit-worthiness is supported ex post through loan performance data. Results show that relational aspects of the online social network help mitigate information asymmetry in the lending process, and that a critical success factor of the industry is to better reveal and utilize the soft credit information embedded in social networks

Innovation, Learning and Cluster Dynamics

This chapter offers a theory and an analytical framework for the analysis of cluster dynamics, i.e. the innovative performance and evolution of clusters.It develops three types of embedding: institutional embedding, structural embedding (network structure), and relational embedding (type and strength of ties).The analysis is conducted from a perspective of both competence (learning) arising from relations and governance of relational risk, which includes risk of lock-in and risk of spillover.A basic proposition is that innovative clusters face the challenge of combining exploration and exploitation.Hypotheses are specified concerning differences between networks for exploration and exploitation, and concerning combinations and transitions between them.Arguments are presented that in some important respects go against the thesis of the strength of weak ties .Some empirical evidence is presented from recent studies.innovation;organizational learning;clusters;industrial districts;networks

The Small Worlds of Wikipedia: Implications for Growth, Quality and Sustainability of Collaborative Knowledge Networks

This work is a longitudinal network analysis of the interaction networks of Wikipedia, a free, user-led collaborativelygenerated online encyclopedia. Making a case for representing Wikipedia as a knowledge network, and using the lens of contemporary graph theory, we attempt to unravel its knowledge creation process and growth dynamics over time. Typical small-world characteristics of short path-length and high clustering have important theoretical implications for knowledge networks. We show Wikipedia’s small-world nature to be increasing over time, while also uncovering power laws and assortative mixing. Investigating the process by which an apparently un-coordinated, diversely motivated swarm of assorted contributors, create and maintain remarkably high quality content, we find an association between Quality and Structural Holes. We find that a few key high degree, cluster spanning nodes - ‘hubs’ - hold the growing network together, and discuss implications for the networks’ growth and emergent quality

The Structure of Intra-Group Ties: Innovation in Taiwanese Business Groups

Business groups are a network form of multi-business firm that play central economic and technological roles in many emerging economies. We draw from the technology studies literature, complemented by concepts from studies of organizational networks, to investigate how equity, director, and operating ties between firms within groups shape their innovation opportunities. Technology studies suggest that such ties create both opportunities and constraints that influence innovative activity by affiliates and, in aggregate, by a group as a whole - opportunities that arise from access to information, people, money, and other resources, but also constraints that arise from entrenched relationships among different actors. The network literature, in turn, suggests that centrality and density of ties between firms within a group will shape the benefits and constraints. We find that the overall density and individual centrality of the three types of ties affects affiliate and group innovativeness among about 2,000 firms within 263 business groups in Taiwan between 1982 and 2000. Groups that offer affiliates focused access to financial resources and operating knowledge, coupled with autonomy from intra-group competition and strategic interference, often generate fertile opportunities for innovative activity by some of their members. The results also offer implications for multi-business firm innovativeness.

The Italian Corporate Network, 1952-1983: New Evidence Using the Interlocking Directorates Technique

The paper explores the structure of the Italian corporate network by focusing on the relationships between financial - banks, insurances and holdings - and industrial firms in Italy during the period 1952-83 through the analysis of the interlocks that existed between them. By an interlock is meant the link created between two firms when an induvidual belongs to the board of directors of both. The analysis is based on a database - Imita.db - containing data on over 130,000 directors of Italian joint stock companies for the years 1952, 1960, 1972 and 1983. After showing a descriptive statistics of the companies and the directors included in the database, the paper develops a network connectivity analysis of the system. This is integrated by a prosopographic study about the big linkers, defined as those directors cumulating the highest number of offices in each benchmark year. The paper confirms that the Italian corporate network maintained substantial peculiarities in the period investigated. In particular, it argues that interlocks played an important role in guaranteeing the stability of the positions of control of the major private companies and their connections with State-owned enterprises. In 1952 and 1960, the system, centred on the larger electrical companies, showed the highest degree of cohesion. That centre dissolved after the nationalisation of the electricity industry in 1962 and was replaced by a less strong and cohesive one, hinged on banks, insurances and the major finance companies. At the beginning of the 1980s the centre appeared to have been further reshaped with the marginalisation of state-owned enterprises.Italy; Corporate Network; Interlocking directorates; Network Analysis; Big Linkers; Private and State-owned Enterprises

Contacts, Social Capital and Market Institutions - A Theory of Development

This paper links two concepts of social capital to economic development. Social Capital (SC) appears in the litrature, on the individual level, as the number contacts of an agent has and his ability to raise contacts and, on the community level, as norms that help a society to function. In our economy, sold output increases with the creation of business contacts (Relational Capital as one aspect of SC). The cost of creating contacts is determined by community level social capital (CSC) and Market Institutions (MI). We argue that innovation needs the purposeful destruction of old contacts. Policies can provide disincentives to break old contacts and hence affect innovation. High levels of CSC and MI increase the contact rate, i.e. the labour costs of making RC. The former two also decrease the cost of breaking up contacts. Simulations show that our model is able to explain empirical observations regarding social capital.

A Conceptual Model for Enhancing Intra-Group Knowledge Sharing

Knowledge sharing is a social action involving the collective behavior of a group of people. However, prior research on knowledge predominately focused on individual behavior. Furthermore, previous studies did not capture the multiple facets of this group behavior. In this research, we propose and justify a framework for the explanation of knowledge sharing in organization context as a social action, integrating multiple theories, i.e., social capital theory, institutional theory, and adaptive technology structuration theory. A series of propositions are proposed and discussed

Informal networks and knowledge sharing in organizations: case study of GR Group

In the era where knowledge and technology have been advancing, knowledge, together with capital and human resources, has become an essential productive factor, playing a vital role in economic growth and enterprise development. Moreover, knowledge-based economic growth relies principally on enterprise knowledge and technological innovation. Nowadays, communication channels have been evolving so rapidly that the types of knowledge sharing have transferred from traditional administrative orders to diversified, multi-channel and informal ways. From the perspective of networks, social platforms and social capital, more attention has been paid to employee behavior in the past few years. Compared to technology and knowledge innovation of the whole organization, growing emphasis has been placed on knowledge sharing of informal networks built by individual employees. As a supplement to formal organization system, informal network is characterized by versatility, background similarity and excellent communicability, defining its positive effect on knowledge sharing and interaction. Consequently, informal network is the key variable in the innovation performance of modern enterprises. Nevertheless, studies on the informal network of knowledge sharing mainly focus on the overall network instead of on network segmentation. Accordingly, knowledge sharing ways and channels is a research gap now. Therefore, it is essential to further delve deeper into informal networks as a closer scrutiny of such topic is of theoretical value and practical significance.Na era em que o conhecimento e a tecnologia avançam, o conhecimento, juntamente com o capital e os recursos humanos, tornaram-se um fator produtivo essencial, desempenhando um papel extraordinariamente vital no crescimento econômico e no desenvolvimento empresarial. Além disso, o crescimento econômico baseado no conhecimento depende principalmente do conhecimento empresarial e da inovação tecnológica. Atualmente, os canais de comunicação estão evoluindo tão rapidamente que os tipos de partilha de conhecimento foram transferidos das formas administrativas tradicionais para formas diversificadas, multicanais e informais. Do ponto de vista de redes, plataformas sociais e capital social, mais atenção tem sido dada ao comportamento dos colaboradores nos últimos anos. Para compreendermos melhor a inovação nas organizações precisamos de estudar a partilha de conhecimento nas redes informais construídas pelos colaboradores. Como complemento aos sistemas formais da organização, a rede informal caracteriza-se pela sua versatilidade, pela comunicabilidade excelente, provocando um efeito positivo na partilha do conhecimento e na interação entre as pessoas. Consequentemente, as redes informais são as variáveis chave no desempenho de inovação das empresas modernas. No entanto, os estudos sobre as redea informais de partilha de conhecimento concentram-se principalmente na rede geral, e não na segmentação da rede
