Our findings using baseline characteristics at age 64 reveal that enrollees in Medicare Advantage are advantageously selected on multiple measures of health status such as Charlson Comorbidity Index (CCI) scores, out-of-pocket costs, utilization, while differentially selected on demographic characteristics. Furthermore, using predicted Medicare Advantage utilization based on observable characteristics, we find even stronger evidence of advantageous selection, suggesting that observable characteristics at age 64 systematically predict which enrollees would benefit most from Medicare Advantage's features, indicating forward-looking selection behavior.</p>\u0000 </div>","PeriodicalId":48105,"journal":{"name":"Journal of Policy Analysis and Management","volume":"45 2","pages":""},"PeriodicalIF":2.4,"publicationDate":"2026-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147384114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

I examine both the short- and long-term impacts of the California Green Building Standards Code (CALGreen), comparing homes constructed just before and after its implementation in 2010. The findings show that, on average, CALGreen homes use 11.7% less water than comparable pre-code homes, with savings persisting over time at approximately 10.9%. Notably, engineering-based (ex ante) estimates of water savings are nearly twice as large as the realized reductions, likely reflecting the “offsetting behavior” effect. The analysis further reveals that most water savings occur during warmer months when outdoor water use peaks. In addition, CALGreen homes exhibit lower sensitivity to temperature fluctuations, with smaller increases in use during hotter months and smaller reductions during cooler months. Finally, when accounting for compliance costs and the opportunity cost of water, the results suggest that CALGreen policy passes a cost-effectiveness test. These findings highlight the effectiveness of building codes as a durable policy tool for achieving long-term water conservation in fast-growing, semi-arid regions.</p>","PeriodicalId":48105,"journal":{"name":"Journal of Policy Analysis and Management","volume":"45 2","pages":""},"PeriodicalIF":2.4,"publicationDate":"2026-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/pam.70089","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146198770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On average, estimated treatment effects are about twice as large when outcomes are measured at the application stage as when they are measured on final benefit receipt.
