Use of econometric models to estimate expenditure shares.


Journal Article

To investigate the use of regression models to calculate disease-specific shares of medical expenditures.Medical Expenditure Panel Survey (MEPS), 2000-2003.Theoretical investigation and secondary data analysis.Condition files used to define the presence of 10 medical conditions.Incremental effects of conditions on expenditures, expressed as a fraction of total expenditures, cannot generally be interpreted as shares. When the presence of one condition increases treatment costs for another condition, summing condition-specific shares leads to double-counting of expenditures.Condition-specific shares generated from multiplicative models should not be summed. We provide an algorithm that allows estimates based on these models to be interpreted as shares and summed across conditions.
