Does It Pay to Know Prices in Health Care?
利用获取新价格信息的时间差异，研究发现消费者在了解价格后支付的医疗费用显著降低，但保险覆盖抑制了价格信息的利用。
Consumers rarely know the price of medical care before they consume it. I use variation in the timing of access to a new source of price information to show how access to and search for price information leads consumers to pay significantly less for care. I provide suggestive evidence that insurance coverage inhibits the use of price information, rationalizing the relatively low rates of search. The results indicate that availability of price information could have large impacts on prices even in the absence of general equilibrium effects.
