A General Equilibrium Model Incorporating Social Concerns

Andrew Postlewaite宾夕法尼亚大学SBR-9511952 私家侦探建议将正在进行的研究扩展到“婚姻模式”，其中有一个预先匹配的投资/储蓄的选择，影响所产生的盈余匹配对将分享。 该提案有八个相关的分项目：（1）解决了有储蓄的婚姻模型中均衡存在性的技术问题，（2）证明了在配对中有效分割剩余的不可能性，（3）证明了在非常一般的假设下弱承诺均衡的存在性，（4）将婚姻模型扩展到只有一个“性别”的情况，“（5）将婚姻模式扩展到两个以上群体的情况。(6)解释投资中的羊群行为，（7）扩展以前关于“混合”均衡的工作，（8）研究政治过程为相对财富提供非市场利益的模型。

Andrew Postlewaite University of Pennsylvania SBR-9511952 The P.I. proposes to extend on-going research into "marriage models" in which there is a pre-match choice of investment/savings that affects the resulting surplus the matched pair will share. The proposal has eight related sub-projects: (1) resolve technical questions on the existence of equilibrium in marriage models with savings, (2) demonstrate the impossibility of efficiently dividing the surplus in matched pairs, (3) demonstrate the existence of weak-commitment equilibrium under very general assumptions, (4) extend the marriage model to the case of only one "sex," (5) extend the marriage model to the case of more than two groups., (6) explain herd behavior in investment, (7) extend previous work on "hybrid" equilibria, and (8) investigate models in which a political process provides a nonmarket benefit to relative wealth.
