Efficiently Restructuring Sovereign Debt via Arctic Auctions with Convex Costs
Jugal Garg, Edwin Lock, Vijay V. Vazirani
We study the problem of computing competitive equilibria in the Arctic product-mix auction, originally developed for the Icelandic government for exchanging blocked financial accou…
Decentralized Trading Networks: Equilibria and Fairness
Simon Finster, Paul W. Goldberg, Edwin Lock +1
We explore stability and fairness considerations in decentralized networked markets with bilateral contracts, building on the trading networks framework [Hatfield et al., 2013]. In…
The Computational Intractability of Not Worst Responding
Mete Åeref Ahunbay, Paul W. Goldberg, Edwin Lock +3
Finding, counting, or determining the existence of Nash equilibria, where players must play optimally given each others' actions, are known to be computational intractable problems…
Decentralized Convergence to Equilibrium Prices in Trading Networks
Edwin Lock, Benjamin Patrick Evans, Eleonora Kreacic +4
We propose a decentralized market model in which agents can negotiate bilateral contracts. This builds on a similar, but centralized, model of trading networks introduced by Hatfie…
