Peer Pressure
研究个体如何通过施加成本影响邻居行为，区分正压力（降低行动成本）和负压力（提高不行动成本），分析其对福利和帕累托最优的影响。
We present a model where agents care about their neighbors' actions and can pressure them to take certain actions. Exerting pressure is costly for the exerting agent and it can impact the pressured agents by either lowering the cost of taking the action (which we call "positive pressure") or else by raising the cost of not taking the action (which we call "negative pressure"). We show that when actions are strategic complements, agents with lower costs for taking an action pressure agents with higher costs, and that positive pressure can improve societal welfare. More generally, we detail who gains and who loses from peer pressure, and identify some circumstances under which pressure results in fully (Pareto) optimal outcomes as well as circumstances where it does not. We also point out differences between positive and negative pressure.
