摘要
双重合约的内外合约就是,没有参与特定相关合约(称为内部合约)的其他人,对于内部合约产生了(外部性)影响,则上述其他人一定是同内部合约参与人达成了另外的其他合约即外部合约。双重合约是一个普遍的存在,婚姻就是其中的一种。双重合约的内、外合约既具有统一联系又存在区别。内外合约可以是排他性质不同的合约,其中一定程度内公外私性质的双重合约,是包括婚姻在内的一般组织的基本特征。根据合作博弈与讨价还价理论,可以建立双重合约下的婚姻稳定模型,其中包括合约效用、会计成本、机会成本、交易成本等重要变量。分析这些变量随社会经济条件的变化,可以解释人类婚姻规模、形式和稳定性的历史演变。
A dual contract is both an internal and external contract, whereby other people, not involved in the specific contract （the internal contract）, exert influence on the internal contract （externality）. Then such other people must have reached another contract, that is, external contract, with the participants of the internal contract. The dual contract is a universal existence, marriage being one of such contracts. There are unified relationship and difference between the internal and external contract of the dual contract. The internal and external contract can be a contract of different exclusive nature, and to some extent, the dual contract with the internal public and external private nature is the basic feature of the general organization, including marriage. In accordance with the theories of cooperative game playing and bargaining, a marriage stabilization model can be established under the dual contract, involving such vital variables as contract effect, accounting cost, opportunity cost and transaction cost, etc. The analysis of such variables which evolve with the change of socioeconomic conditions may help to explain the historical revolution of marriage scale, marriage form, and andmarriage stability.
