A correcting formula for the estimation of harmonics-to-noise ratios (HNR) based on ensemble-averaging techniques is derived. The original method yields a biased approximation which is more accurate as the number of averaged pulses (N) increases. However, the method treats gradual waveform changes incorrectly as noise, which is worsened for large values of(More)
This article deals with efficiency improvement and how to identify appropriate benchmarks for inefficient firms to imitate. We argue that the most relevant benchmark is the most similar efficient firm. Having interpreted similarity in terms of input endowments, the problem reduces to find the closest reference firm on the efficient subset of the isoquant.(More)
