摘要本文利用Gabaix(Eonometrica 2011)最近提出的一种方法，首次研究了对最大企业的特质冲击在制造业企业进口动态中的作用。对于德国，我们发现了进口呈幂分布的证据，以及进口在行业中的分布可以被描述为厚尾分布的证据。结果表明，对超大型企业的特殊冲击对2010/2011年的进口动态是重要的，但在2009/2010年不是。
Abstract This paper uses an approach recently suggested by Gabaix (Eonometrica 2011) to investigate for the first time the role of idiosyncratic shocks to the largest firms in the dynamics of imports by firms from manufacturing industries. For Germany we find evidence that imports are power-law distributed and that the distribution of imports in the industries can be characterised as fat-tailed. Results show that idiosyncratic shocks to very large firms are important for the import dynamics in 2010/2011 but not in 2009/2010.
