Which of the following is true of an information good or service?

Consider a situation where an insurance contract has a negative expected value for the
purchaser. Under this insurance policy, the premium paid exceeds the expected payout.
Is it rational to buy this insurance? Give explanation with reason.
A large health insurance plan pays for 90% of the cost of emergency room and other
hospital visits but only 20% of the cost of an individual's purchases of prescription
drugs. How might this affect the individual's health-care decisions? Why might the
result lead to high health-care spending?

At her current per-day consulting fee, a freelance marketing consultant finds herself
with as many jobs as she can handle. In fact, over the past six months, she has been
hired by nine of the ten clients who have made queries about her services. At her

work. Evaluate the consultant's pricing strategy.
