Note: This table presents results from three multinomial logit regressions. All three regressions model the choice between traditional Medicare (TM, the omitted category), Medicare Advantage (MA) HMO/PPO plans, and MA private fee-for-service (PFFS) plans. The first regression was run on a 5% sample of beneficiaries aged 65 and above, and included county-level fixed effects. The second model was run on a 20% sample beneficiaries aged 66 and above, and included condition category indicator variables. The third model was run on beneficiaries aged 65 and 67, and included county-level fixed effects. The coefficient estimates are suppressed for the county fixed effects and condition category terms. Standard errors are clustered at the county level.
