An Application of the Melitz Model
Additional Document Info
When the Melitz model is implemented in practice, the industrial productivity distribution is often assumed to be of Pareto form. In this case, a fundamental relationship >-1 must hold to guarantee the convergence of the industrial average productivity, where is the concentration degree of the industrial productivity Pareto distribution and is the substitution elasticity across varieties in the industry. This paper estimates the concentration degrees of the Pareto distribution in industrial productivity and industrial substitution elasticities using firm-level data of 40 Chinese manufacturing industries between 1998 and 2007. However, the paper shows that the above fundamental assumption >-1 does not hold for nearly all the industries for Chinese firm-level data. An explanation is proposed as a result of the distorted firm size and productivity for Chinese characteristics. 2013 John Wiley & Sons Ltd.
