Prior works use spatial autoregression models (SARs) which implicitly assume that each individual in the network has the same peer effects on others. Mechanically, they conclude the key player in the network to be the one with the highest centrality. However, when some individuals are more influential than others, centrality may fail to be a good measure. I develop a model that allows for individual-specific endogenous effects and propose a two-stage LASSO procedure to identify influential individuals in a network","authors_text":"Sida Peng","cross_cats":["stat.AP","stat.ME"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"econ.EM","submitted_at":"2019-08-02T00:05:05Z","title":"Heterogeneous Endogenous Effects in Networks"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1908.00663","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:e965d1959b694b27ba523dfc4cfdfb618fdb59541398f572572a6a26d88df8e0","target":"record","created_at":"2026-07-04T23:51:07Z","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":"6b4feecedc138489f38aa3137a52b81161a5e0f198daa574e84180a6871fa326","cross_cats_sorted":["stat.AP","stat.ME"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"econ.EM","submitted_at":"2019-08-02T00:05:05Z","title_canon_sha256":"cf25c140a7e4cfcf1f64719d80c9dfa8ccdf378d7068a279ce51947517c77197"},"schema_version":"1.0","source":{"id":"1908.00663","kind":"arxiv","version":1}},"canonical_sha256":"ec8027f5a95d0c67f42ab2230921fe98e67f943e47287ee983efeb38a27bf360","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ec8027f5a95d0c67f42ab2230921fe98e67f943e47287ee983efeb38a27bf360","first_computed_at":"2026-07-04T23:51:07.942495Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T23:51:07.942495Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"zNj8MGhnUpw8ZFtZv4Ih8NXbqvVNtLjzDek4qAiNfi/jjyNBDrXr7IExFQIllVh6e26n2Y8A5nZX+cMbSXo3Bw==","signature_status":"signed_v1","signed_at":"2026-07-04T23:51:07.942881Z","signed_message":"canonical_sha256_bytes"},"source_id":"1908.00663","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e965d1959b694b27ba523dfc4cfdfb618fdb59541398f572572a6a26d88df8e0","sha256:ba67e454ea597ef54e7ce41331719341e6b017fd41e7f05e28907d6ad62e0765"],"state_sha256":"dce68ab0ccdb834bbac6b6944735f97a60d8b504827d563480ccb70fd4fe66f3"}
