TABLE IV.
Intervention Impacts for 2008 Wisconsin Follow-up Survey Respondents, by Outcome
| A. Consumer costs in dollars | |
| Predicted 2007 consumer cost (2007 plan) | −111* (48) |
| Actual 2007 consumer cost (2007 plan) | −137 (217) |
| Predicted 2008 consumer cost (2008 plan) | −93 (169) |
| Predicted 2009 consumer cost (2008 plan) | −159 (170) |
| B. Quality | |
| Proportion dissatisfied with quality, non-cost features | 0.032 (0.033) |
| Proportion rating overall plan as fair or poor | −0.026 (0.041) |
Notes. All estimates are of the coefficient on the intervention indicator from linear regression based on equation (4), as described in the text, using the same vector of covariates as in Table III. Costs are differences from Yb, the predicted 2007 consumer cost of the 2006 baseline plan. Predicted 2007 costs are based on drugs reported in the baseline 2006 survey. Predicted 2008 and 2009 costs are based on drugs reported in the 2008 follow-up survey. Sample size is 285 in rows 1–3, 241 in row 4, and 302 in rows 5–6. Standard errors are in parentheses.
