This provides ...

The disease model is susceptible-infected-susceptible (SIS), and adaptation is rewiring of links bet...

First, we characterize the equilibrium use of information: complementarity heightens the sensitivity of equilibrium actions to public information, raising aggregate volatility, whereas substitutability heigh...
