这是1968年欧洲计量经济学学会欧洲大会上阅读的一篇法语原文的英文修订版。它回顾了调查的结果，在不完全知识下评估了几个著名的决策标准。(平均收入最大化，弗洛因德-马科维茨准则，安全第一计划，机会约束，焦点损失约束，与自然博弈。)概述了两个主要观点：(1)在理论层面上，所进行的实验支持这样的观点，即，除非提供给被代表的决策者的可能性范围尽可能大，并且考虑到与手头决策相关的任何决策可能性，否则像弗洛因德这样的模型没有得到充分的检验。与此相关的一个特别特点是，只有在允许土地收购的情况下，才有可能区分债务、风险挂钩和非挂钩模式。(2)这一理论发现的实际对应物是，在应用任何风险决策标准之前，有必要仔细开发风险厌恶系数的使用，如果这种联系被适当地表达出来，那么在这些标准中选择一个标准的影响相对较小。然而，只有一次相当粗糙的实验就得出了这样的结果。因此，在进行任何概括之前，必须对它们进行证实。为此目的，必须进行进一步的实验，从目前的研究中得到的主要教训可能是有兴趣在这一方向上作出努力。A.abr.
This is a revised English version of an original French paper read at the European Congress of the Econometric Society, 1968. It reviews the results of investigations appraising several well known decision criteria under imperfect knowledge. (Maximizing average income,Freund-Markowitzcriterion, safety first programme, chance constraint, focus-loss constraint, game against nature.) Two main ideas are outlined: (1) On a theoretical plane the experiments carried out support the opinion that a model such asFreund'sis not sufficiently tested unless the possibilities range that was offered to the represented decision maker is as large as possible, and makes allowance for any decision possibility in connection with the decision at hand. Related to this and especially characteristic is the fact that the separation between indebtedness risk-linked and unlinked models is possible only when land acquisition is allowed. (2) The practical counterpart of that theoretical finding is the necessity to develop the use of risk aversion coefficients carefully before applying any risk decision criterion, and the comparatively small impontance of the choice of one criterion among those proposed, if this linkage is suitably expressed. However, such results have been yielded by only one rather crude experiment. Consequently, they have to be corroborated before any generalization. Further experiments must be undertaken for this purpose, and the main lesson to be drawn from the present research is perhaps an interest in pursuing efforts in that direction. A. abr.
