Collusion and Price Dispersion [PDF]
SSRN Electronic Journal, 2005 While there are suggestions in applied cartel studies that price dispersion changes when cartelization of a market occurs, there are few theoretical or empirical analyses of this effect. This article surveys the thin economic literature on the link between overt collusion and price dispersion. Formal theories and observation of cartel behaviour suggest

American Journal of Political Science, EarlyView.Abstract In divided societies, can museums contribute to healing and recovery? While efforts to memorialize past violence typically aim to promote tolerance and reconciliation, remembering could exacerbate divisions in recovering societies where the past is deeply contested. We examine a transitional justice museum exhibit in Northern Ireland.

American Journal of Political Science, EarlyView.Abstract Building a strong and effective state requires revenue. Yet, in many low‐income countries, citizens do not make formal payments to the state or forego engaging with the state altogether due to vulnerability to opportunistic demands by state agents. We study two randomized interventions in Kinshasa, Democratic Republic of the Congo, designed to

On a decentralized trustless pseudo-random number generation algorithm
Journal of Mathematical Cryptology, 2017 We construct an algorithm that permits a large group of individuals to reach consensus on a random number, without having to rely on any third parties. The algorithm works with high probability if there are less than 50 of colluding parties in the group.

Efficient collusion in optimal auctions [PDF]
We study collusion in an IPV auction with binary type spaces. Collusion is organized by a third-party than can manipulate participation decisions. We characterize the optimal response of the seller to different threats of collusion among the bidders.
