-theoretic model of attack and defense of a network in which the defender's objective is to maintain network connectivity and the … attacker's objective is to destroy a set of nodes that disconnects the network. The conflict at each node is modeled as a … which a single random [minimal] set of nodes that disconnects the network is attacked …

linked fields. Our analysis uses 1.8 million U.S. patents and their citation properties to map the innovation network and its … strength. Past innovation network structures are calculated using citation patterns across technology classes during 1975 …-1994. The interaction of this pre-existing network structure with patent growth in upstream technology fields has strong …

review is on studies that use network analysis paying special attention to those that apply complex analysis techniques …

, however, a conflict arises between efficiency and pairwise stability, due to a “size externality” not internalized by firms …

In this paper we compare the profitability of a merger to the profitability of a partial ownership arrangement and find …

When workers send applications to vacancies they create a network. Frictions arise if workers do not know where other … workers apply to (this affects network creation) and firms do not know which candidates other firms consider (this affects … network clearing). We show that those frictions and the wage mechanism are in general not independent. Equilibria that exhibit …

We explore network effects on generosity for different network dimensions. To this end we elicit multiple network … matters for friendship ties but that structural network variables are important in all network dimensions. Importantly, these … effects are not invariant across different network dimensions. We also find that individual characteristics are unrelated with …

We study upstream horizontal mergers and their potential efficiency gains. We show that an upstream horizontal merger … can give rise to two efficiency-enhancing effects when firms trade through two-part tariffs. It increases R&D investments … and decreases wholesale prices when downstream competition is not too strong. Examining whether the merger's potential …
