The introduction opens with historical motivation about bubbles and resale speculation, then contrasts the classic Harrison-Kreps assumptions (no shorting, constant carry costs) with the paper's model, which uses asymmetric quadratic carry costs. It sketches the HJB characterization and previews comparative-statics and planner results. Two paragraphs position the paper against heterogeneous-belief and search-friction literatures, followed by a roadmap. The body proceeds from existence and the PDE, to comparative statics and limiting cases, to resale and delay options illustrated with examples, to a planner interpretation. The conclusion restates the contribution and applies it to synthetic CDOs and the subprime bubble. Extensions and proofs are placed in appendices.",231  "writing_profile_keywords": [232   "continuous-time model",233   "heterogeneous beliefs",234   "short selling",235   "HJB equation",236   "resale option",237   "delay option",238   "comparative statics",239   "planner's problem",240   "proofs in appendix",241   "historical motivation"242  ],243  "confidence": 0.85,244  "notes": "Purely theoretical paper with no tables or figures.
