The literature of private provision of public goods suggests that incentive to contribute is inversely related to group size. This paper empirically tests this relationship using field data from Chinese Wikipedia, an online encyclopedia. We exploit an exogenous reduction in group size as a...

Abstract: We study the capacity of business associations - private, formal, noncommercial organizations designed to promote the common business interests of their members - to support contract enforcement and collective action. Inspired by recent empirical literature, our theoretical framework...

This paper introduces an extended definition of service networks. The service network definition, which can be used for classifying service networks, comprises two parts: the service network declaration and the service network specification. The service network specification consists of the...

IT service businesses can achieve economies of scale and scope faster than in traditional product businesses. In particular, as IT service platforms will become the founding infrastructure of our economies, the analysis and understanding of the value that a service platform can generate is of...

Based on the promising developments in Cloud Computing technologies in recent years, commercial computing resource services (e.g. Amazon EC2) or software-as-a-service offerings (e.g. Salesforce.com) came into existence. However, the relatively weak business exploitation, participation, and...

One of the most important properties of self-organized networks is their scale-free property. Prior research proved empirically and theoretically that scale-free networks emerge under the preferential attachment rule. However, a few empirical studies also show that empirical networks diverge...

Web2.0 users can create new services by combining existing Web2.0 services that offer open programming interfaces. This system of service composition forms a network, which we call the Web2.0 service network. A node of the Web2.0 service network represents a service. A link between two nodes...

One of the important characteristics of Web2.0 is the collaboration between Web2.0 service providers. They allow users (i.e., providers, developers, consumers) to combine their services. The prerequisite for this collaboration is openness of the Web2.0 service system. Although the Web2.0...

We construct the topology of business networks across the population of firms in an emerging economy, Pakistan, and estimate the value that membership in large yet diffuse networks brings in terms of access to bank credit and improving financial viability. We link two firms if they have a common...

Using an exhaustive database on academic publications in mathematics, we study the patterns of productivity by world mathematicians over the period 1984-2006. We uncover some surprising facts, such as the absence of age related decline in productivity and the relative symmetry of international...
