Symmetric Positive Equilibrium Problem: A Framework for Rationalizing Economic Behavior with Limited Information
扩展了PMP方法，提出对称正均衡问题框架，用于分析多经济单位、异质性行为和多种限制性投入，并通过意大利农场案例展示其在复杂政策下的应用。
Abstract The PMP methodology is extended to deal with many economic units, self‐selection arising from heterogeneous economic behavior, and multiple limiting inputs. The novel structure for the analysis of this type of problems acquires the name “symmetric positive equilibrium problem.” This methodology is articulated in three phases that parallel those one of positive mathematical programming. The recovery of a cost function that calibrates the base‐year decisions of each economic unit is realized within a maximum entropy framework. The methodology is illustrated by the analysis of a sample of Italian farms that operate under the complex policy mandates of the European Union.
