We examine the impact of China's economic stimulus plan in 2008 on the total factor productivity (TFP) of China's listed firms. We hypothesize that firms operating in regions characterized by greater resource misallocation would experience a more pronounced decline in TFP following the implementation of the stimulus plan. To gauge the extent of resource misallocation, we employ the proportion of state‐owned...
In this paper, an efficient algorithm to deal with convolutive blind source separation of communication signals in frequency domain is presented. The classical JADE algorithm is adopted to perform linear complex-valued ICA in each frequency bin. To solve the permutation ambiguity problem, a new permutation technique based on high-order statistics is proposed. Then, a post processing procedure called...
