Hierarchies of Processors with Endogenous Capacity
研究处理器能力可选择的层级结构，发现高效层级具有三个简单特征：同层能力一致、高层能力更高、无跨级汇报。
Capacity is defined as the number of information items a processor can handle in a given time. This note studies the properties of a hierarchy of processors in which the capacities of processors are choice variables. The hierarchy must pay each processor it decides to employ a wage which is an increasing function of the processor's capacity. It is shown that efficient hierarchies tend to be characterized by three simple properties: (i) within any given level, capacity is uniform, (ii) across levels, the higher the level, the higher the capacity, and (iii) no skip-level reporting occurs.Journal of Economic LiteratureClassification Numbers: D21, J31, L23.
