Strict Fairness at What Cost? Envy-Free Contracts with Subsidies
Matteo Castiglioni, Junjie Chen, Yingkai Li
We study algorithmic fair contract design, where a principal designs task-level contracts and fairly delegates a set of tasks to a set of agents. Prior work reveals a fairness-reve…
Algorithmic Fair Contracts
Matteo Castiglioni, Junjie Chen, Yingkai Li
We initiate the algorithmic study of fair contract design. A principal assigns multiple tasks to heterogeneous agents and chooses task-level linear contracts; agents differ in cost…
Fair Team Contracts
Matteo Castiglioni, Junjie Chen, Yingkai Li
A principal selects a team of agents for collaborating on a joint project. The principal aims to design a revenue-optimal contract that incentivizes the team of agents to exert cos…
