Final answer:
The 2008 Oregon health insurance experiment studied the difference in medical care utilization between individuals with complete insurance and those with cost-sharing measures. It found that deductibles and co-payments reduced the level of moral hazard, leading to a decrease in health care consumption. However, this decrease did not affect the health status of the individuals.
Step-by-step explanation:
The 2008 Oregon health insurance experiment effectively examined the effects of health insurance coverage by studying the difference in medical care utilization between individuals with complete insurance and no out-of-pocket costs, and individuals with deductibles and co-payments. The study found that individuals with cost-sharing measures consumed about one-third less health care, suggesting that deductibles and co-payments reduced the level of moral hazard. However, despite consuming less health care, those individuals did not appear to have any difference in health status.
