Purpose: This paper studies the relationship between network ties (NT) and transactive memory systems (TMS), observed through three dimensions—specialization (TMSS), credibility (TMSCR), and coordination (TMSCO)—in the presence of leadership (LDR) as a moderating variable, in university...

With the embedding of internet technology, the entrepreneurial model has been gradually developing from traditional single linear channel into network platform with symbiotic multi-platform. Platform leadership is the most important part of the new one and has been caught greatest attention....

In this paper we test the celebrated `Strength of weak ties' theory of Granovetter (1973). We test two hypotheses on the network structure in a data set of collaborating economists. While we find support for the hypothesis of transitivity of strong ties, we reject the hypothesis that weak ties...

It is a challenging task to understand the complex dependency structures in an ultra-high dimensional network, especially when one concentrates on the tail dependency. To tackle this problem, we consider a network quantile autoregres- sion model (NQAR) to characterize the dynamic quantile...
