Such systems should be fair and stable. Showing that traditional approaches fail to satisfy these requirements, we propose the Shapley mediator. We show that the Shapley mediator fulfills the fairness and stability requirements, runs in linear time, and is the only economically efficient mechanism satisfying these properties.","authors_text":"Moshe Tennenholtz, Omer Ben-Porat","cross_cats":["cs.IR"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.GT","submitted_at":"2018-06-04T05:08:56Z","title":"A Game-Theoretic Approach to Recommendation Systems with Strategic Content Providers"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1806.00955","kind":"arxiv","version":3},"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:f5a299fa3bc5ab5668ef72e86f4f31da190dd2718a1fdc155819813f5034390e","target":"record","created_at":"2026-05-18T00:02:53Z","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":"7b119924e10ca4c559a426779f7918e5723a9f8e82b8c4559679166387d265f6","cross_cats_sorted":["cs.IR"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.GT","submitted_at":"2018-06-04T05:08:56Z","title_canon_sha256":"6201a9d0872b7843b4585b64f449aab5869996240f17b834c644e532dd78f457"},"schema_version":"1.0","source":{"id":"1806.00955","kind":"arxiv","version":3}},"canonical_sha256":"7ec2ffa9758f3b73c299c37b6460b8da6b8af3daa005f93567ceb68ef773938c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7ec2ffa9758f3b73c299c37b6460b8da6b8af3daa005f93567ceb68ef773938c","first_computed_at":"2026-05-18T00:02:53.195149Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:02:53.195149Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"nTBfy8nOJmNSF6VG8xdUqbY0Wl45jy7maLOjCAloyjk1K+hs3o8h641n/rlW1xQQ1zkiii9tnFUEnITAIxkbDw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:02:53.195717Z","signed_message":"canonical_sha256_bytes"},"source_id":"1806.00955","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f5a299fa3bc5ab5668ef72e86f4f31da190dd2718a1fdc155819813f5034390e","sha256:b14f3fdc6a38fe488e766784cf2b00f1eca408274b8af87dba967798b4318bce"],"state_sha256":"c4f0b5d315216996eb0ef05998d28af29ab143779eccbe1d9baf37916520a8f6"}
