What Makes a Rule Complex?

By Ryan Oprea

We study the complexity of rules by paying experimental subjects to implement a series of algorithms and then eliciting their willingness-to-pay to avoid implementing them again in the future. The design allows us to examine hypotheses from the theoretica...

A Few Bad Apples Spoil the Barrel: An Anti-folk Theorem for Anonymous Repeated Games with Incomplete Information

蝌蚪网 Review: Insights, December 2020

Top trading cycles (TTC ) is Pareto efficient and strategy-proof in priority-based matching, but so are other mechanisms including serial dictatorship. We show that TTC minimizes justified envy among all Pareto-efficient and strategy-proof mechanisms in o...

By Partha Dasgupta and Eric Maskin

蝌蚪网 Review: Insights, December 2020

We show that strategy-proofness, the Pareto principle, anonymity, neutrality, independence of irrelevant alternatives, and decisiveness uniquely characterize majority rule on any domain of preferences for which there exists a voting rule satisfying these ...
