The informational role of prices
扩展了价格框架，将其应用于公共物品和自然资源等非标准市场环境，论证了价格接受行为能提升价格的信息价值，并有助于政策制定。
The paper extends the framework of prices beyond the standard market setting to incorporate public goods and natural resources. These are settings where one does not usually think of market solutions. Core theory has established that price-taking behaviour by both suppliers and consumers, i.e. the absence of strategic considerations, greatly improves the informational value of prices, and hence of economic equilibria. This also holds when using market-like institutions to allocate resources for public goods. Policy effectiveness in many areas can be improved when agents are induced to reveal, voluntarily and truthfully, their willingness-to-pay or production costs.
