摘要

我们将约束集上的一个阶称为平行四边形阶,它保证了对于任何矢量,argmin{p⋅x:x∈A}在产品阶中随着A在平行四边形阶中的增加而增加。利用这一结果,我们可以描述导致正常需求的效用/生产函数,以及与之密切相关的边际成本随要素价格上升的生产函数。通过归纳超模态概念,我们还描述了要素互补的生产函数的特征。在不确定条件下的决策方面,我们的新集阶导致了多先验模型中一阶随机支配的自然概括。

Comparative Statics With Linear Objectives: Normality, Complementarity, and Ranking Multi-Prior Beliefs

Comparative Statics With Linear Objectives: Normality, Complementarity, and Ranking Multi-Prior Beliefs

We formulate an order over constraint sets , called the parallelogram order, which guarantees that argmin{p ⋅ x:x ∈ A} increases in the product order as A increases in the parallelogram order, for any vector . Using this result, we characterize the utility/production functions that lead to normal demand as well as the closely related class of production functions with marginal costs that increase with factor prices. By generalizing the concept of supermodularity, we also characterize the class of production functions for which factors are complements. In the context of decision-making under uncertainty, our new set order leads to natural generalizations of first-order stochastic dominance in multi-prior models.

期刊介绍: Econometrica publishes original articles in all branches of economics - theoretical and empirical, abstract and applied, providing wide-ranging coverage across the subject area. It promotes studies that aim at the unification of the theoretical-quantitative and the empirical-quantitative approach to economic problems and that are penetrated by constructive and rigorous thinking. It explores a unique range of topics each year - from the frontier of theoretical developments in many new and important areas, to research on current and applied economic problems, to methodologically innovative, theoretical and applied studies in econometrics. Econometrica maintains a long tradition that submitted articles are refereed carefully and that detailed and thoughtful referee reports are provided to the author as an aid to scientific research, thus ensuring the high calibre of papers found in Econometrica. An international board of editors, together with the referees it has selected, has succeeded in substantially reducing editorial turnaround time, thereby encouraging submissions of the highest quality. We strongly encourage recent Ph. D. graduates to submit their work to Econometrica. Our policy is to take into account the fact that recent graduates are less experienced in the process of writing and submitting papers.
