The introduction motivates the question with the scale of benchmark-referenced OTC markets. It then previews three welfare channels (entry, matching, search costs), cases where a benchmark lowers welfare, an optimal-mechanism result, and dealers' incentives to introduce benchmarks. A brief literature comparison and a roadmap follow. An institutional section describes how benchmarks are used. The core search model with homogeneous dealer costs compares equilibria with and without a benchmark, derives the welfare comparison and dealer incentives, and characterizes the optimal mechanism. An extension adds heterogeneous dealer costs to study matching efficiency. A short discussion of manipulation precedes a conclusion with policy remarks. Proofs are in the appendices.",222 "writing_profile_keywords": [223 "search model",224 "OTC markets",225 "price transparency",226 "mechanism design",227 "welfare comparison",228 "proposition-proof structure",229 "policy relevance"230 ],231 "confidence": 0.88,232 "notes": "Purely theoretical; there are no tables or empirical estimates.
