This study investigated environmental efficiency considering heterogeneity for 192 thermal
power plants in the Yangtze River Delta of China from 2009 to 2011. We evaluated …

Market distortions can generate resource misallocations across heterogeneous firms and
reduce aggregate productivity. This paper measures market distortions and aggregate …

В работе рассматривается вопрос об оценивании эффективности фирм отрасли. В
настоящий момент наиболее известными эмпирическими подходами для анализа …

In this paper, we analyze the technical efficiency and CO 2 reduction potentials of German
power and heat plants, using a non-parametric sequential Data Envelopment Analysis. We …

Separation of vertical integrated electricity sector and removal of entry barriers for power
generation investment were advocated by China's electricity market reform in 2002. While …

Our paper investigates productivity, output growth and total factor productivity (TFP) growth
using a novel single-index smooth-coefficient stochastic frontier approach and two firm-level …

This paper examines TFP (total factor productivity) growth and economies of scale of Korean
fossil-fuel power GENCOs (generation companies) between 2001 and 2012. For this …

We propose a semiparametric estimator for varying coefficient models when the regressors
in the nonparametric components are measured with error. Varying coefficient models are …

The authors propose to estimate a varying coefficient panel data model with different
smoothing variables and fixed effects using a two-step approach. The pilot step estimates …

This paper proposes a constrained nonparametric method of estimating an input distance
function. A regression function is estimated via kernel methods without functional form …
