摘要翻译:
本文通过对日本工业生产数据的分析,探讨了经济周期的成因。方法有谱分析法和因子分析法。利用随机矩阵理论,我们证明了两个最大特征值是显著的。利用分类数据所揭示的信息,我们确定第一个主导因素是总需求,第二个因素是库存调整。它们不能被合理地解释为技术冲击。我们还证明,就两个主导因素而言,出货量领先生产四个月。此外,样本外检验表明,即使在2008-09年经济衰退的情况下,该模型也仍然有效。由于2008-09年期间的产出下降是由外生出口下降造成的,因此它为确定第一个主导因素是总需求提供了另一个理由。所有的发现都表明,商业周期的主要原因是实际需求冲击。

英文摘要:
We explore what causes business cycles by analyzing the Japanese industrial production data. The methods are spectral analysis and factor analysis. Using the random matrix theory, we show that two largest eigenvalues are significant. Taking advantage of the information revealed by disaggregated data, we identify the first dominant factor as the aggregate demand, and the second factor as inventory adjustment. They cannot be reasonably interpreted as technological shocks. We also demonstrate that in terms of two dominant factors, shipments lead production by four months. Furthermore, out-of-sample test demonstrates that the model holds up even under the 2008-09 recession. Because a fall of output during 2008-09 was caused by an exogenous drop in exports, it provides another justification for identifying the first dominant factor as the aggregate demand. All the findings suggest that the major cause of business cycles is real demand shocks.
