摘要：
we argue that firm-level agency conflicts not only counter the role of network structure in the propagation of shocks but they can have a significant impact on system-wide behavior that differs from those predicted based on network structure alone. this implies that corporate governance can play an important role in macro fluctuations.
we consider a collection of firms linked through equity cross-holdings whose managers can make investment decisions in response to an exogenous shock. prior work concludes that more integrated networks amplify shocks. we find that if managers are subject to default costs or limited liability, this effect is reversed because their investment decisions mitigate the spread of an initial shock. in the face of moral hazard, however, their investment choices amplify an initial shock. in particular, when the network is fully diversified, the aggregate effect of idiosyncratic shocks does not diminish as received wisdom would suggest.
