This paper studies bidder collusion with communication in repeated auctions when no side transfer is possible. It presents a simple dynamic bid rotation scheme with co-ordinates bids based on communication history and enables intertemporal transfer of bidders’ payoffs. The paper derives a sufficient condition for such a dynamic scheme to be an equilibrium and characterises the equilibrium payof...

We prove the cutoff phenomenon for random walk on n-lifts of finite weighted graphs, even when base graph G lift is not reversible. The mixing time w.h.p. tmix=h−1logn, where h a constant associated to G, namely entropy its universal cover. Moreover, this smallest possible among all G. In particular case vertex with d/2 loops, d even, we obtain d-regular graph, as did Lubetzky and Sly in (Duke ...

Abstract The literature on civility navigates the gravitational pulls of binary camps: sceptics tend to emphasize how it operates as an instrument power; optimists its emancipatory potentials. While some scholarship has attempted reconcile these perspectives by showing can be both negative and positive, such theorization tends describe this relation in terms ambivalence. approaches rightly indi...
