Welfare Economics of Decision Making with Changing Preferences
研究决策树需具备什么性质才能保证，当所有代理人完全短视时，不存在偏好使得精明均衡被帕累托占优。结果表明只有最平凡的问题才满足此性质，并推广到非完全短视的代理人，用工会与股东冲突的例子说明。
The paper considers the properties a decision tree needs to guarantee that there are no preferences such that the sophisticated equilibrium is Pareto dominated when all agents act completely myopically. It shows that the only decision trees with this property are the most trivial problems. The analysis is generalized to agents who are not completely myopic and gives an example of union and shareholder conflict to illustrate the results.
