We employ mixture convexity and sub-additivity, which capture the idea that producing \"balanced\" outputs is less costly than producing ``extreme'' ones. Our analysis leads to a novel class of cost functions that can be expressed in terms of R\\'enyi divergences between signal distributions across states. This representation allows for deviations from the standard posterior-separable cost, thereby accommodating recent experimental evidence. We also characterize two simpler special cases, which can be written as either","authors_text":"Davide Bordoli, Ryota Iijima","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"econ.TH","submitted_at":"2025-08-29T20:36:51Z","title":"Convex Cost of Information via Statistical Divergence"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2509.00229","kind":"arxiv","version":1},"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":"sha256:1a304a2d0744cf5d091a4fac94c2befb58b8bea507049358a483faf55e754410","target":"record","created_at":"2026-07-05T12:02:11Z","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":"9ed259ef6492457cd850bba39cb30964bc9219fd0a120ef5991ccfc2bd0982af","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"econ.TH","submitted_at":"2025-08-29T20:36:51Z","title_canon_sha256":"151e18623e7c6987ac2bd147bf973a436cb9a8110180228acd26332639c558f2"},"schema_version":"1.0","source":{"id":"2509.00229","kind":"arxiv","version":1}},"canonical_sha256":"7f2fbe266d13cc012b5359c3bc87bf823269a1a944913bc8b1c918945c3c8d99","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7f2fbe266d13cc012b5359c3bc87bf823269a1a944913bc8b1c918945c3c8d99","first_computed_at":"2026-07-05T12:02:11.796069Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T12:02:11.796069Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"lgPTWSu/SSR01yxYI/XAsw5gtSYLcfdxCboH2BUjSzJ8bYLBBnqmiC20hPn3QNdVJhwBkiECaXkGVA9t03KUBA==","signature_status":"signed_v1","signed_at":"2026-07-05T12:02:11.796539Z","signed_message":"canonical_sha256_bytes"},"source_id":"2509.00229","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1a304a2d0744cf5d091a4fac94c2befb58b8bea507049358a483faf55e754410","sha256:97cec2947d859b9bc4cf3facaf61f37c6d3813a9ffb5d147a66d653e3b9d84ad"],"state_sha256":"a78351f63c9a5aef9921ece48c95cfe2c2f3a809ab68a038c516fcc33dd828f8"}
