Solving the Arctic Product-Mix Auction
Elizabeth Baldwin, Paul Klemperer, Edwin Lock
Arctic product-mix auctions allow budget-constrained bidders to express preferences over multiple substitute goods. We give the first strongly polynomial algorithm to find the comp…
Combinatorial Contracts Through Demand Types
Elizabeth Baldwin, Paul Duetting, Michal Feldman +1
In the combinatorial action model of contract design, a principal delegates a complex project to an agent, incentivizing a subset of actions from a ground set of actions, via a…
The Equilibrium Existence Duality: Equilibrium with Indivisibilities & Income Effects
Elizabeth Baldwin, Omer Edhan, Ravi Jagadeesan +2
We show that, with indivisible goods, the existence of competitive equilibrium fundamentally depends on agents' substitution effects, not their income effects. Our Equilibrium Exis…
Solving Strong-Substitutes Product-Mix Auctions
Elizabeth Baldwin, Paul W. Goldberg, Paul Klemperer +1
This paper develops algorithms to solve strong-substitutes product-mix auctions. That is, it finds competitive equilibrium prices and quantities for agents who use this auction's b…
