social network (aka Jackson那套)算比较新,但现在主要也就新在实证上 (像Acemoglu et al. (2011)这种基于network的social learning model也都是十年前就开始的东西了)。network本身(e.g., public good location)早就做烂了,旧的比如
Hansen P, Thisse JF (1981) Outcomes of voting and planning: Condorcet, Weber, and
Rawls locations. Journal of Public Economics 16:1–5
新的比如
Peters, Hans, Souvik Roy, and Soumyarup Sadhukhan (2019) Unanimous and strategy-proof probabilistic rules for single-peaked preference profiles on graphs. accepted in Mathematics of Operations Research
