Approximating Combinatorial Contracts with Arbitrary Costs

We study single-agent combinatorial contracts under linear payments. Under a reward share $\alpha\in[0,1]$, an agent chooses a subset $S$ of $n$ hidden actions, generating reward $f(S)$ at cost $c(S)$, to maximize $\alpha f(S)-c(S)$, while the principal receives $(1-\alpha)f(S)$. For nonnegative additive rewards and mo...
