摘要翻译：
我们发展了一个信息获取的公理理论，它抓住了信息生产中边际成本不变的思想：产生两个独立信号的成本是它们的成本之和，以一半的概率产生一个信号的成本是其原始成本的一半。这些公理与Blackwell单调性和连续性条件一起决定了信号直到参数向量的代价。这些参数有明确的经济解释，决定了区分状态的难度。我们认为，这个成本函数是一个多功能的建模工具，导致比互信息更现实的预测。

英文摘要：
We develop an axiomatic theory of information acquisition that captures the idea of constant marginal costs in information production: the cost of generating two independent signals is the sum of their costs, and generating a signal with probability half costs half its original cost. Together with Blackwell monotonicity and a continuity condition, these axioms determine the cost of a signal up to a vector of parameters. These parameters have a clear economic interpretation and determine the difficulty of distinguishing states. We argue that this cost function is a versatile modeling tool that leads to more realistic predictions than mutual information.
