Notes. Conditional logit models estimated with individual fixed effects, as in equation (6). Additional coefficients not shown in the table were estimated for the 2006 choice and for each plan; the estimation sample is therefore limited to plans selected by at least 2 individuals in the sample and to individuals choosing a plan selected by at least two individuals. 7 observations with predicted consumer costs > $20k were dropped. Column 1 uses the 2007 follow-up survey respondents, with 401 individuals, 32 plans, and 113 missing cost observations. Columns 2 and 3 use the 2008 follow-up survey respondents, with 265 individuals, 27 plans, and 54 missing cost observations. Standard errors are in parentheses.
p-value < 0.05.
