This paper reports an experimental investigation on two mechanisms for the so-called King Solomon Dilemma, where one of them fails to implement the social choice rule dynamically. We compare the two mechanisms in terms of their welfare, incentive and learning properties. Copyright...

We consider a model of social interactions in which agents are assumed to acquire information from others through a certain sampling process that generates an influence network. These networks comprise a wide array of options depending on the level of correlation assumed between agents' in and...

We study a setting in which individual players choose their partners as well as a mode of behavior in 2×2 anti-coordination games – games where a player’s best response is to choose an action unlike that of her partner. We characterize the equilibrium networks as well as study the effects...

The objective of this work is to analyze how social networks coevolve with other dimensions of agents' choice. We present a model where agents choose their neighbors as well as a mode of behavior in 2 × 2 anti-coordination games, i.e. games where an individual's best response is to behave...

We propose a model where agents located in a social network decide whether or not to exert effort to provide a local public good. We assume that they have strong incentives to free-ride on their neighbors’ effort decisions. We characterize the equilibria of the induced game. We also study a...

This paper studies how a behavior spreads in a population. We consider a network of interacting agents whose actions are determined by the actions of their neighbors, according to a simple diffusion rule. We find, using a mean-field approach, the threshold for the spreading rate above which the...

Some behaviors, ideas or technologies spread and become persistent in society, whereas others vanish. This paper analyzes the role of social influence in determining such distinct collective outcomes. Agents are assumed to acquire information from others through a certain sampling process, that...
