Networks are the problem : confronting the social capital consensus
Too many ties : divergent interests with the falling costs of digital networking
Ties too weak : insufficient firm-specific social investments to mobilize diversity
Entrenched brokers and ossified bridges : monopolies of information and control
Scale too free : negative externalities of inequality in social capital
Persistence : managerial intervention transience and the reemergence of agency problems
Agentic function of the executive : strategic social capital and the work-from-home experiment
Network governance : reinterpreting organizational design and boundaries
Network agency over the lifecycle : entrepreneurship and innovation ecosystems
A research agenda : more cases, more models, more experiments.
