Though managerial ties are substitutes for the weak market-supporting institutions in developing and emerging countries, little is known about contingent value of these credit markets. In this study, we disintegrate into political financial ties, examine their effect on access to finance. Using agency theory, propose that reduce information asymmetry between firms, politicians banks, culminatin...

Social capital and social support are two key constructs in the study of social networks and health. Despite their importance, little research has sought to examine the characteristics of those social ties by which individuals access social capital and support resources. Network diversity - a key structural feature in accessing social capital - refers to a person's broad but generally weak and ...

Ethnic Networks and Employment Outcomes We analyse the effect of strong and weak ties on the individual probability of finding a job. Using the dynamic model of Calvó-Armengol and Jackson (2004), two results are put forward: (i) the individual probability of finding a job is increasing in the number of strong and weak ties; (ii) the longer the length of ties, the lower is this effect. We approx...

In today’s globalized world, firms are increasingly seen shifting from the traditional innovation model 1 which relied on a firm’s internal R&D to the more porous open innovation paradigm which utilizes resources both internal and external to a firm to come up with innovations. However success in the open innovation paradigm is contingent upon some internal and external factors of a firm. This ...

Widely used information diffusion models such as Independent Cascade Model, Susceptible Infected Recovered (SIR) and others fail to acknowledge that information is constantly subject to modification. Some aspects of information diffusion are best explained by network structural characteristics while in some cases strong influence comes from individual decisions. We introduce reinvention, the ab...

As an invisible informal structure embedded within organization, social network is closely related to the knowledge management activities and strategies of organization. The has potential obtain right information or at time through weak ties realize effective sharing in organization with strong ties, commercialize using capital achieve economic success.

Detecting strong ties among users in social and information networks is a fundamental operation that can improve performance on a multitude of personalization and ranking tasks. There are a variety of ways a tie can be deemed “strong”, and in this work we use a data-driven (or supervised) approach by assuming that we are provided a sample set of edges labeled as strong ties in the network. Such...

Highly distributed, loosely organized, independent, informal work organizations sometimes manage both joint efforts and collective welfare at least as well as centralized bureaucracies do. This aligns closely with the view that markets are superior to bureaucracies as ways of organizing both joint efforts and collective welfare. There are other forms of work organization between perfect markets...
