| Abstract: | Incremental mortality and cost effects of intensive procedures for treating heart attacts among the elderly are estimated by using panel instrumental variables techniques. Incremental effects are identified by comparing trends in procedure use, hospital costs and mortality between hospitals that adopt intensive technologies to corresponding trends at nonadoptive hospitals. The identification assumptions required for "difference-in-differences" estimation are formalized and empirical evidence on their validity is presented. |
