We study the evolution of the social norm of "cooperation" in a dynamic environment. Each agent lives for two periods … completely drives equilibrium play, leading to a social norm of high or low cooperation. In intermediate cases, the impact of … leverage their greater visibility to influence expectations of future agents and overturn social norms of low cooperation. We …

financial institutions. Focusing on a multi sector economy linked through a supply network, we show how structural properties of … the supply network determine both whether aggregate volatility disappears as the number of sectors increases (i … aggregate output from its mean) to sector-specific volatility and to the structural properties of the supply network …

We study the direct and spillover effects of local state capacity using the network of Colombian municipalities. We … model the determination of local and national state capacity as a network game in which each municipality, anticipating the … (using GMM, simulated GMM or maximum likelihood). To do so we exploit both the structure of the network of municipalities …

We develop a theoretical model of security investments in a network of interconnected agents. Network connections … strategic substitutes. In a general (non-symmetric) network, this implies that underinvestment by some agents will encourage … symmetric or locally tree-like. We also characterize the impact of network structure on equilibrium and optimal investments …

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 …
