【摘要】：传统理论认为,外部性是市场失灵的一种重要表现,导致了资源配置非帕累托最优。内生外部性理论研究表明,外部性仅仅是合约外效应表现,根源于产权界定模糊不清或交易费用过高;合约内总效应与合约外总效应边际值相等时,即可实现资源配置帕累托最优。将外部性作为内生要素纳入签约行为之中,是有效实现外部性内部化的重要前提,庇古税仅仅是内生外部性理论分析范式中的一个特例。通过研究外部性与签约时机、未签约代理人数量、博弈方式、签约信息分布的关系,可以明晰外部性内生化过程机理。通过设计分而治之策略、定价方案、Shapley值法、菜单式合约与第三方合约,可以有效实现外部性内生化。
[Abstract]:According to traditional theory, externality is an important manifestation of market failure, which leads to non-Pareto optimal allocation of resources. The theoretical study of endogenous externality shows that externality is only the manifestation of extracontractual effect, which originates from vague definition of property rights or high transaction costs. The Pareto optimal resource allocation can be realized when the marginal value of the total effect within the contract and the total effect outside the contract is equal. It is an important premise to bring externality into the contract behavior as an endogenous factor. Pigoux tax is only a special case in the theoretical analysis paradigm of endogenous externality. By studying the relationship between externality and signing opportunity, the number of unsigned agents, the game mode and the distribution of contract information, the mechanism of externality endogenous biochemical process can be clarified. By designing divide-and-conquer strategy, pricing scheme, Shapley value method, menu contract and third party contract, externality internalization can be realized effectively.
