In particular, we consider the setting of selling to $n$ bidders whose values are drawn from $n$ independent but not necessarily identical distributions. We work in the robust auction design regime, where we assume the seller has no knowledge of the bidders' value distributions and must design a mechanism that is prior-independent. While there have been many strong results on prior-independent auction design in the i.i.d. setting, not much is known for the heterogeneous setting, even though the latter is","authors_text":"Aranyak Mehta, Di Wang, Guru Guruganesh, Kangning Wang","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.GT","submitted_at":"2022-07-19T17:42:24Z","title":"Prior-Independent Auctions for Heterogeneous Bidders"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2207.09429","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:128463d12580561c4e6a22a173f4fe782f0d240257e3abbb716d1f516068d3b8","target":"record","created_at":"2026-07-05T07:09:43Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"de3f7c20ce5eda08b18f967e36553d359f241b057a0e07f5bd653d53e2903e3e","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.GT","submitted_at":"2022-07-19T17:42:24Z","title_canon_sha256":"e4736083e39f6adf164824efae168f8ba3dbfd79db1d08ac14b03ad4b3fee5d4"},"schema_version":"1.0","source":{"id":"2207.09429","kind":"arxiv","version":2}},"canonical_sha256":"74fbd94ba59a7b0c58c368b3ed80dd72314302d744b9493c5e7207dcc7b64396","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"74fbd94ba59a7b0c58c368b3ed80dd72314302d744b9493c5e7207dcc7b64396","first_computed_at":"2026-07-05T07:09:43.181419Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T07:09:43.181419Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"zx5MAwMV82LFwynCnWAV/Hd8QVAN1qzqpbwJx6bQQ4ovMg0T2KYQW/53R0+hydI1ld/qtu1z5rfwDPdXHNNABA==","signature_status":"signed_v1","signed_at":"2026-07-05T07:09:43.181918Z","signed_message":"canonical_sha256_bytes"},"source_id":"2207.09429","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:128463d12580561c4e6a22a173f4fe782f0d240257e3abbb716d1f516068d3b8","sha256:274e946d74b13c40826c1811ec368a5286c6be82d5a9569abb51f20f8e3f142f"],"state_sha256":"c7d30dbc3973b0e523da6c21344730d9bec170e4d300321c24dee0cd2d3b01d9"}
