Experimental Tests of an Allocation Mechanism for Private, Public or Externality Goods
通过十一组三部分实验，检验了一种自愿、一致同意的投标机制（EXTERN）在私有品、公共品和外部性商品分配中的表现，发现私有品实验均达成一致，公共品实验九组成效，且私有品需求揭示程度低于公共品。
The results of eleven three-part experiments provide data on the performance of a voluntary, unanimity, bidding mechanism (EXTERN) for private, public and externality goods. The important feature of this mechanism is that all of its information requirements are endogenous. All of the private and externality good experiments reached unanimity agreement; nine of the public good experiments reached agreement. Measures of demand revelation tended to be lower for the private good than the public good. This tendency carried over into the private and public components of the externality experiments which lowered allocative efficiency.
