Production Smoothing Evidence from Physical-Product Data
用38个行业或产品组别的实物数据重新检验生产平滑模型,发现约三分之二的组别中生产比发货更平滑,但欧拉方程估计的成本参数通常不精确且符号与模型预测不符。
The authors reconsider the paradox that the variance of production often exceeds the variance of shipments, a result that casts doubt on the production smoothing model of inventory behavior. Most studies of production smoothing have analyzed two-digit SIC dollar-value data from Commerce Department surveys. In contrast, this paper reexamines disaggregated physical-product data and finds that production is smoother than shipments in about two-thirds of the thirty-eight industry or product groupings considered. However, doubts about the model persist; most notably, Euler equation estimates of the model's cost parameters are usually imprecise and often do not have the signs postulated by production smoothing models.
