Accessibility of Pareto optima
研究了非试探过程与规划程序，这些动态过程能在不降低任何参与者效用的情况下实现有效分配，与仅在均衡时发生交易的传统试探过程形成对比。
Non-tâtonnement processes and planning procedures have been defined in different economic contexts, as dynamic processes to reach efficient allocations, with or without price adjustment, satisfying the property that, along the process, the utility of every agent is non-decreasing and transactions can occur, thus making a clear distinction with the study of tâtonnement processes whose goal is to reach competitive equilibria with transactions occurring only at equilibrium.
