Tina just passed three years as a MegaCorp employee and reacts to having health insurance by taking up several dangerous sports because now she knows that the insurance plan will pay for any injuries that she may sustain.

b. Asymmetric information.

c. The moral hazard problem.

d. The personal mandate.
