　　不確定條件下的個(gè)人決策貝葉斯理論規(guī)定，個(gè)人斷定一個(gè)實(shí)用功能，在事件的概率分布，并評(píng)估其期望效用的基礎(chǔ)上，每一幕。我們?cè)噲D推廣這種模式，社會(huì)決策。我們所考慮的聚集規(guī)則要求社會(huì)的信仰和價(jià)值觀分別為個(gè)人的信仰和價(jià)值觀的仿射聚集。它是公知的，標(biāo)準(zhǔn)的帕累托條件是不與這些單獨(dú)的聚合規(guī)則兼容。兩個(gè)自然延伸帕累托條件的話建議。內(nèi)Anscome-奧曼框架，我們表明，不變帕累托條件等價(jià)于分開(kāi)的聚集(定理1和2)，而套頭帕累托條件是等效于野蠻框架(定理3)內(nèi)的單獨(dú)聚合。

　　原文：Bayesian theory for individual decision-making under uncertainty prescribes that individuals posit a utility function, a probability　distribution over events and evaluate each act on the basis of its　expected utility. We attempt to generalize this model to social　decision-making. The aggregation rules we consider require society's　beliefs and values to be respectively the affine aggregation of　individuals beliefs and values. It is well-known that the standard　Pareto condition is not compatible with such separate aggregation　rules. Two natural extended Pareto condition are then suggested.　Within the Anscome-Aumann framework, we show that the Invariant Pareto　condition is equivalent to separate aggregation (Theorems 1 and 2)　while the Hedging Pareto condition is equivalent to separate　aggregation within the Savage framework (Theorem 3).
