A constructive contribution follows: correction formulas, extrapolation methods and sufficient identifying conditions. The introduction closes with extended literature positioning against Lucas, tax-investment papers and Keane-Wolpin. The body develops the model, then the shock-response propositions, identifying assumptions, external validity/extrapolation, a calibrated tax example and alternative technologies. The conclusion restates the theory-evidence gap and the constructive prescription; proofs are in the appendix.",262 "writing_profile_keywords": [263 "methodological critique",264 "analytical propositions",265 "comparative statics versus shock responses",266 "model as laboratory",267 "bias correction formulas",268 "external validity",269 "dynamic uncertainty",270 "numerical illustration",271 "quotation-driven motivation"272 ],273 "confidence": 0.8,274 "notes": "Genre is borderline between theoretical and methodological; classified as methodological because the purpose is inference guidance for empiricists.
