摘要翻译：
从序贯信息成本最小化的角度研究了信息的间接成本。一个关键的次可加性条件与单调性等价地刻画了由任何直接信息成本生成的间接成本函数类。增加一个额外的（均匀的）后验可分性条件等价地表征了从任何直接成本产生的间接成本，有利于增量证据。给出了先验独立的直接成本生成后验可分的间接成本的充要条件。

英文摘要：
  We study the indirect cost of information from sequential information cost minimization. A key sub-additivity condition, together with monotonicity equivalently characterizes the class of indirect cost functions generated from any direct information cost. Adding an extra (uniform) posterior separability condition equivalently characterizes the indirect cost generated from any direct cost favoring incremental evidences. We also provide the necessary and sufficient condition when prior independent direct cost generates posterior separable indirect cost.
