Aggregation and Testing of the Production Smoothing Hypothesis
分析生产平滑模型在加总层面的含义，指出加总可能导致检验生产平滑假说的偏差，甚至使基于产量与销量相对方差的检验失效。
This paper examines the aggregate implications of the production smoothing model. The analysis indicates that aggregation can be a source of bias distorting tests of production smoothing based on the relative variance of production and sales. It is shown that, depending upon the relative variability of different types of market shocks firms face, the aggregation bias can be so severe as to render the test of the production smoothing hypothesis invalid.
